摘要:
The numbers of pulses of the CW signal and the CCW signal of the optical fiber gyro during a predetermined sampling duration are detected by samplers. An abnormality determiner determines that the optical fiber gyro is normal if at least one of the pulse numbers is greater than or equal to a threshold value. If both pulse numbers are smaller than the threshold value, the abnormality determiner determines that an abnormality, such as a circuit break, a bad connection, etc., has occurred, and outputs the result of determination to an output unit. The abnormality determiner may determine an abnormality on the basis of the presence/absence of quantization noise.

An angular velocity detected by an angular velocity sensor (10) is integrated by a small angle matrix calculator (12) and a matrix adding calculator (14), and then restored as a posture angle (angular velocity posture angle) by a matrix posture angle calculator (16). A posture matrix is calculated by a tilt angle calculator (22) and an acceleration matrix calculator (24) and an acceleration detected by an acceleration sensor (20) is restored as a posture angle (acceleration posture angle) by a matrix posture angle calculator (26). Low pass filters (18, 28) each extract a low range component, the difference between the two is calculated by a differencer (30), and only the drift amount is extracted. A subtracter (32) removes the drift amount from the angular velocity posture angle and the result is output from an output device (34). In addition, a posture angle matrix calculator (36) converts the result to a posture matrix, which it feeds back to the matrix adding calculator (14).
摘要:
A structure is presented in which it is easy to adjust, to a determined value, distance between electrodes of a condenser formed in an electrostatic capacity-type displacement sensor. A displacement sensor has a conductive lower layer, an insulating layer stacked on the conductive lower layer and a conductive upper layer stacked on the insulating layer. The conductive lower layer is divided into a first lower region and a second lower region by a groove penetrating the conductive lower layer. The insulating layer is stacked on the conductive lower layer at selected portions. The conductive upper layer is stacked on the insulating layer at selected portions. The conductive upper layer has a beam connected via the insulating layer to the first lower region and the second lower region at a pair of ends of the beam. The conductive upper layer has a first upper portion forming one of electrodes of a first condenser. The first upper portion extends from a position above the first lower region to a position above the second lower region. The insulating layer is not formed between the first upper portion and the first lower region, but is formed between the first upper portion and the second lower region.

A facsimile communication managing data including transmission/reception mode, a telephone number of a called or a calling subscriber, etc. is printed out at a predetermined time interval. Each time a facsimile communication is made, the facsimile communication managing data is stored in a memory. A period of time defining a time interval at which the stored managing data are read out is set through a keyboard. An elapse of the period of time is detected and a detection signal is issued. If the detection signal is output during a non-busy state of the facsimile machine, the managing data are read out of the memory immediately after the occurrence of the detection signal and then printed in a printing station of the facsimile machine, whereas if the detection signal is output during a busy state of the facsimile machine, the managing data are read out after the facsimile machine is turned to the non-busy state and printed in the printing station thereof.

The control device controls the dot-forming elements to also effect a secondary or supplemental recording operation for recording at least one secondary line between adjacent two lines of the plurality of primary lines, according to secondary line data. The secondary line data is prepared based on at least one of the two sets of primary line data which represent the adjacent two primary lines, respectively, such that the secondary lines improve a quality of the images recorded on the recording medium.
摘要:
An attitude angles calculation device (14) calculates attitude angles of a robot from the output values of an acceleration sensor (10). An attitude angles comparison device (16) compares attitude angles in a specified attitude which have been set in a register (20) and the attitude angles which have been detected, and outputs their differences to a correction values calculation device (18). The correction values calculation device (18) outputs correction devices to a zero point correction device (26) or a sensitivity correction device (28), so as to eliminate these differences. If would also be acceptable to set the attitude angles which are set in the register (20) from an input device (22).

Upon receiving a command for changing a target facsimile machine (Yes in S103), the present facsimile machine 1 receives the new forwarding number (S105-S108). The present facsimile machine 1 changes a forwarding number stored in the EEPROM 18 to the newly inputted forwarding number. Then, the present facsimile machine 1 starts receiving incoming image information from remote facsimile machines (S111) and stores them into the RAM 16. Upon receiving a command for transmission of a status list (Yes in S113), the present facsimile machine 1 produces a status list indicating the newly-stored forwarding number (S115). Then, the present facsimile machine 1 transmits the status list to a remote facsimile machine which has transmitted the status list transmission command. The user existing at that remote facsimile machine visually confirms the newly-stored forwarding number appearing on the status list, and transmits a transmission start command to the present facsimile machine 1. Upon receiving the transmission start command (Yes in S117), the present facsimile machine 1 starts transmitting the image information presently stored in the RAM 16 (S119).
摘要:
A magnetic sensor element 1 includes a substrate 10, a conductive layer 12 of a conductive material, and a magnetic layer 11 of a magnetic material, which encloses the conductive layer 12. AC is applied to the element from a drive power source 50, and a detector 60 detects an impedance change due to an external magnetic field. The magnetic layer 11 is bestowed with magnetic anisotropy in a direction orthogonal to the direction of energization of the element 1. With the provision of the conductive layer 12 of conductive material and also with magnetic anisotropy imparted to the magnetic layer 1, the element 1 may be made a low resistivity element. A reactance change and a resistance change of the element due to an external magnetic field change, thus can be effectively detected in drive frequencies two orders of magnitude lower than in the case of a prior art magnetic sensor element. The magnetic anisotropy of the magnetic layer 11 is controlled to prevent magnetic field detection dynamic range variations with drive frequency.

A vibration-sensing device (10) with high sensitivity includes a torsion bar (16) fixed on both ends thereof to a frame, a tuning fork-shaped vibrating member (12) joined with and supported by the torsion bar (16), and first and second torsion vibrating bodies (14,15) symmetrically projected from the torsion bar (16). The torsion bar (16), the tuning fork-shaped vibrating member (12), and the torsion vibrating bodies (14,15) constitute a torsion vibrating system. The application of an angular velocity to the vibration-sensing device (10) under the condition of plane vibrations of first and second vibrating tines (12a, 12b) of the first tuning fork-shaped vibrating member (12) along an X axis generates Coriolis forces to drive torsion vibration of the first tuning fork-shaped vibrating member (12) round the torsion bar (16), thereby driving torsion vibration corresponding to the angular velocity in the torsion vibrating system. The torsion vibration is amplified by the first and second torsion vibrating bodies (14,15) and detected by torsion vibration-detecting piezoelectric elements (20a,20b) attached to the torsion vibrating bodies (14,15). An angular velocity sensor using the vibration-sensing device, and a method of adjusting the sensitivity of the device are also provided.

A torque detecting apparatus for measuring the amount of magnetostriction of a rotary magnetic material which transmits torque by means of a magnetic sensor, and detecting the transmitted torque on the basis of the measured amount of magnetostriction. The apparatus comprises a magnetic sensor for measuring the amount of magnetostriction of the rotary magnetic material, a demagnetization coil which is opposed to the rotary magnetic material so as to restore the rotary magnetic material magnetized by a disturbing magnetic field to the state of zero magnetization, a demagnetization circuit for applying an oscillating current to the demagnetization coil so as to generate in the rotary magnetic material a periodic damping oscillating magnetic field having the maximum value larger than the coercive force of the rotary magnetic material; and a trigger circuit for outputting a drive timing signal for the demagnetization circuit. The transmitted torque is detected without being influenced by a disturbing magnetic field.
