摘要： A rotation angle detecting device includes a signal generator, a magnetic rotor and a rotation angle calculating unit that calculates a rotation angle θ of the rotor based on the output signals of the signal generator. The signal generator includes a magnetic rotor that has a permanent magnet and a shaft connectable with the rotating object and at least three magnetic sensor elements disposed in the magnetic field to generate a plurality of output signals when the rotor rotates. The rotation angle calculating unit calculates a first candidate of the rotation angle θ from a first pair of the three output signals, examines whether the first candidate of the rotation angle θ is normal or not and calculates a next candidate of the rotation angle θ from another pair of the three output signals if the first candidate of the rotation angle θ is not normal, examines whether the next candidate of the rotation angle θ is normal or not, repeats the above two steps until a next candidate of the rotation angle θ is judged normal, and outputs one of the first and next candidates of the rotation angle θ as a formal rotation angle if it is judged normal.

The rotation angle detecting device includes a magnet unit fixed to the first member and a pair of magnetic sensors fixed to the second member to provide output signals whose phase is different from each other at 90 degrees in angle. The magnet unit includes a pair of disk plates that has the same magnetic poles at the same circumferential positions and is disposed at a prescribed axial distance and a shaft that is made of magnetic material to support the disk plates at the center thereof. The magnetic unit provides a uniform magnetic field in a space around the shaft between the pair of disk plates, and a pair of magnetic sensors is disposed in the space.

摘要： A torque sensor has a torsion bar coaxially in alignment with input and output shafts, a ring shaped magnet fixed to an axial end of the input shaft, a pair of magnetic yokes fixed to an axial end of the output shaft, and a magnetic sensor for detecting magnetic flux density generated between the pair of magnetic yokes. Each of the magnetic yokes is provided with claws, which are circumferentially spaced at constant intervals, and whose number is equal to that of each of N and S poles alternately arranged circumferentially in the magnet. Each, center of the claws coincides with a boundary between immediately adjacent N and S poles of the magnet, when the torsion bar is not twisted. The magnetic sensor is inserted into an axial gap between the pair of magnetic yokes without contacting the magnetic yokes.

摘要： A data transfer system allowing high-quality transfer of streaming data through a network having a relatively large delay variation in data delivery is disclosed. When transferring streaming data in packets from a server computer to a client computer through a repeater provided in the network, the repeater buffers a streaming packet for a set time period before forwarding it to the client computer. The set time period is determined so that a receiving time interval of packets at the client computer is substantially equal to a sending time interval of packets at the server computer.

摘要： A magnetic sensor unit includes an actuator motor and a magnetic position sensor. The actuator motor has a magnetic circuit including motor magnets. The magnetic position sensor includes a sensor magnet and a hall element for detecting magnetic flux. Magnet clearances are formed between the motor magnets. The hall element is disposed outside of the motor to detect the magnetic flux in a direction penetrating through the magnet clearances, and which is perpendicular to a direction from one of the motor magnets to the other. In this disposition of the hall element, it is restricted that the hall element detects leaking magnetic flux from the motor magnets.

摘要： In analyzing the concentration of an objective component contained in a sample gas by a gas analyzer, an output of the gas analyzer is corrected at a fixed point by applying the relationship between the concentration of a coexistent gas and a span sensitivity of the objective component to make it possible to simply correct the effect of the coexistent gas. In addition, by inputting, at the time of the calibration of the gas analyzer, the information on to what extent the base gas composition differs from the average amount of the actual sample along with the concentration amount of the objective component in the calibration gas, the sensitivity adjustment coefficient is determined by taking into account the effect amount which is previously stored in the gas analyzer, by which the effect amount of the span sensitivity by the difference of the base gas compositions in the calibration gas and the sample gas is suppressed, and the effect of the coexistent gas is canceled to the best possible extent.
