Abstract: A shaft (270) is provided along the Z-axis on a semiconductor substrate (100), whose upper surface extends along the XY-plane, to fit a rotor (200) consisting of dielectric material. The rotor is supported by the shaft so that it can be inclined and can be rotated. The peripheral portion of the rotor constitutes weight bodies (211, 212), and stators (111, 115) consisting of conductive material are disposed at the periphery thereof. When a.c. voltages of predetermined period are delivered to the stators, the rotor is rotated while floating in accordance with the principle of the induction motor. When angular velocity .omega.x about the X-axis is applied to the substrate 100, Coriolis force Fcz in the Z-axis positive direction is applied to the weight body (211) passing through the X-axis with velocity component in the Y-axis positive direction so that it moves away from the substrate. Coriolis force -Fcz in the Z-axis negative direction is applied to the weight body (212) passing through the X-axis with velocity component in the Y-axis negative direction so that it moves close the substrate. Capacitance elements C1, C2 are formed by fixed electrodes (141AB, 142AB) on the substrate and movement electrodes (231, 232) on the rotor. Difference between electrostatic capacitance values of both the capacitance elements is obtained to detect magnitude of applied Corioli's force. The magnitude of the detected Corioli's force is outputted as a value of angular velocity .omega.x about the X-axis. Even under the environment where acceleration is applied, the acceleration component is canceled by obtaining difference.

Abstract: Upper electrodes (A1 to A5) are disposed on an upper surface of a disk-shaped piezoelectric element (10). On a lower surface of the piezoelectric element (10), an annular groove to surround origin O is formed at position corresponding to the upper electrodes (A1 to A5). At the portion where the annular groove is formed, the piezoelectric element (10) includes a flexible portion formed so as to have thin thickness. When the peripheral portion of the piezoelectric element (10) is fixed to the casing, the central portion positioned within the annular groove functions as a weight caused to hang down from the flexible portion. On the lower surface of the piezoelectric element (10), a lower electrode (B) is formed. When force is applied to the weight by acceleration, the flexible portion is bent. As a result, predetermined charges are produced in the upper electrodes (A1 to A5) with the lower electrode (B) being as a reference potential. Accordingly, applied acceleration can be detected. When a predetermined a.c. signal is delivered between the lower electrode (B) and the upper electrodes (A1 to A5), the weight is oscillated in a predetermined direction. Accordingly, angular velocity can be detected on the basis of Coriolis force applied to the weight. Thus, simple sensor capable of detecting both acceleration and angular velocity in three dimensional directions can be realized.

Abstract: An electrode layer is formed on the upper surface of a first substrate, and a processing for partially removing the substrate is carried out in order to allow the substrate to have flexibility. To the lower surface of the first substrate, a second substrate is connected. Then, by cutting the second substrate, a working body and a pedestal are formed. On the other hand, a groove is formed on a third substrate. An electrode layer is formed on the bottom surface of the groove. The third substrate is connected to the first substrate so that both the electrodes face to each other with a predetermined spacing therebetween. Finally, the first, second and third substrates are cut off every respective unit regions to form independent sensors, respectively. When an acceleration is exerted on the working body, the first substrate bends. As a result, the distance between both the electrodes changes. Thus, an acceleration exerted is detected by changes in an electrostatic capacitance between both the electrodes.

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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
