An elementary sensor for sensing a force comprises a transducer for transforming a mechanical deformation to an electric signal, and a first strain generative body (20) including a supporting portion (21) and a working portion (23) connected to the transducer so as to allow the transducer to produce a mechanical deformation on the basis of a displacement relative to the supporting portion of the working portion. By further adding a second strain generative body (30) including a fixed portion (31) fixed at least with respect to the direction of a force to be detected, and a displacement portion (33) connected to the working portion of the first strain generative body, wherein the displacement portion is constructed to produce a displacement based on a given external force relative to the fixed portion to transmit the displacement thus produced to the working portion of the first strain generative body, a force detector applicable to a wide variety of measurement ranges can be realized. Moreover, by allowing the displacement portion to be elongated, a detector suitable for measurement of both force and moment can be provided. In addition, a stylus (306) can be connected to the elementary sensor to apply it to a contact detector, and the elementary sensor can be affixed at the hand of a robot to apply it to a gripper for the robot.

An apparatus for preventing discharge of fuel vapor to the atmosphere by allowing fuel vapor in a fuel tank to be adsorbed by an adsorbing device when a fuel lid is opened. A switch is turned on by the movement of a locking member for locking and unlocking the fuel lid so as to detect the opening of the fuel lid. The arrangement facilitates adjustment of the relative positions of the switch and the locking member. In addition, the switch is turned on when the fuel lid is opened by remote control, while the switch is turned off when the fuel lid is manually closed. The discharge of fuel vapor to the atmosphere during refueling and the influx of fuel vapor into the adsorbing device after the charging of fuel are prevented.

A first substrate having a working region, a flexible region, and a fixed region is prepared. Resistance elements are formed within the flexible region on a first surface of this substrate. A portion of the first substrate is removed. Thus, the flexible region is allowed to have flexibility. A second substrate is connected to a second surface of the first substrate. The second substrate is cut later into two portions of a working portion and a pedestal. The working portion is connected to the working region of the first substrate, and the pedestal is connected to the fixed region of the first substrate. In order to control displacements in upward and downward directions of the working portion, control substrates are further connected. A force applied to the working portion by acceleration or magnetism is detected as changes in the resistance values of the resistance elements.

A small, high-stiffness torque sensor. An annular deformable body is disposed between left and right side supports. Convex sections protruding from the left side support in a rightward direction are joined to the left side surface of the annular deformable body, and convex sections protruding from the right side support in a leftward direction are joined to the right side surface of the annular deformable body. When force is applied to the right side support and torque around the Z axis acts on the left side support, the annular deformable body is elliptically deformed and the long-axis position of the inner peripheral surface of the annular deformable body moves away from the Z axis while the short-axis position moves closer to the Z axis. The acting torque is detected as a variation in the capacitance value of capacitive elements formed by displacement electrodes and fixed electrodes.

An E-mail communication apparatus relays an E-mail transmitted from a source to a destination, stores information indicating a destination and an electronic certificate of the destination in a correspondence, receives the E-mail in which an address of the source and an address of the destination are specified; refers a certificate storage unit when a transmit command for the E-mail is issued for the E-mail received by a receiving unit, determines whether or not the electronic certificate of the destination of the E-mail is stored and, when the electronic certificate is stored, encrypts the E-mail with the electronic certificate, requests the destination to transmit the electronic certificate when it is determined that the electronic certificate is not stored, and transmits the encrypted request mail to the destination.
摘要:
Static and dynamic acceleration as well as static and dynamic angular velocity are detected with a simple structure. An acceleration detecting section includes a weight body, a pedestal around the weight body, flexible plate-like bridge portions, and piezoresistive elements embedded in the upper surface of the bridge portions. An angular velocity detecting section includes a weight body, a pedestal around the weight body, flexible plate-like bridge portions, and piezoelectric elements fixed to the upper surface of the bridge portions. The pedestals are fixed to a device chassis. When the weight body is displaced by acceleration, the plate-like bridge portions are deflected, so that the acceleration is detected based on the change in the electrical resistances of the piezoresistive elements. When the weight body is displaced by a Coriolis force based on angular velocity while supplying alternating signals to the piezoelectric elements to oscillate the weight body, the plate-like bridge portions are deflected, so that the angular velocity is detected based on charge generation in the piezoelectric elements.

A sensor comprises a semiconductor pellet (10) including a working portion (11) adapted to undergo action of a force, a fixed portion (13) fixed on the sensor body, and a flexible portion (13) having flexibility formed therebetween, a working body (20) for transmitting an exerted force to the working portion, and detector means (60-63) for transforming a mechanical deformation produced in the semiconductor pellet to an electric signal to thereby detect a force exerted on the working body as an electric signal. A signal processing circuit is applied to the sensor. This circuit uses analog multipliers (101-109) and analog adders/subtracters (111-113), and has a function to cancel interference produced in different directions. Within the sensor, two portions (E3, E4-E8) located at positions opposite to each other and producing a displacement therebetween by action of a force are determined. By exerting a coulomb force between both the portions, the test of the sensor is carried out.
