摘要： PURPOSE:To obtain the sensor whose durability is excellent and to improve the assembly workability to a main body member and a moving body by providing a pair of detectors on the main body member, moving a magnetic flux variation member together with the moving body, and varying a magnetic flux of both the detectors by an action of this member. CONSTITUTION:By an action of a magnet 32, a magnetic flux of each coil L1, L2 increases and decreases and their inductance increases and decreases. Also, to the coils L1, L2, a high frequency of prescribed frequency and amplitude is applied in advance, and as for the high frequency after passing through the coils L1, L2, the amplitude is varied in accordance with a variance of the inductance of the coils L1, L2. The variation of the amplitude is detected by a first and second amplitude detecting parts 29, 30, respectively. When an output voltage of this detecting part 29, and an output voltage of the detecting part 30 are denoted as V1 and V2, respectively, the voltage V1 and the voltage V2 are inputted to a non-inversion input terminal of an operational amplifier 34 of a comparing/amplifying circuit 31, and its inversion input terminal, respectively, and a difference (V1 - V2) of both the voltages is amplified by a differential amplifying circuit, and outputted as an output voltage V3 from an output terminal.

摘要： PURPOSE:To easily and correctly set the zero point of a steering handle and shorten the adjusting time by providing a hysteresis between the force applied to an elastic force and an detected output, slightly applying positive and negative displacements to the steering handle, and setting the middle point of detected outputs detected by the displacements to the zero point. CONSTITUTION:When a control box 21 is connected to a program control circuit 25 with a connector 27 and a command to set an adjusting mode is given, the program control circuit 25 is switched to the zero point adjusting mode. When an elastic body 12 is moved to the positive side of backlashes (a), (a') and a detection command is given from the control box 21, the program control circuit 25 receives its value S1. When the elastic body 12 is likewise moved to the negative side, its value S2 is received. The calculation (S1+S2)/2 is performed to obtain the zero point, and it is stored in a memory means 24. The steering force generated by the rotation of a steering handle 11 in the positive or negative direction is detected with the zero point thus set used as the base point thereafter. The zero point is easily and correctly set without performing the adjusting work at the time of assembling, and the efficiency of the adjusting work is improved.

摘要： PURPOSE:To prevent a clutch from being caught during low temperature operation, by providing such an arrangement that a shape memory alloy compression spring is compressed by a bias compression spring during low temperature operation, and accordingly a stopper is drawn toward a piston so as to open a communication hole, resulting in an increase in the stroke of the piston. CONSTITUTION:A valve device is composed of a valve element 50, a bias compression spring 52 and a shape memory alloy compression spring 53. The valve element 50 is adapted to slide toward a crank-shaft 6 and its forward end 50a blocks a communication hole 15c in order to limit the stroke of a piston 16. The bias compression spring 52 urges the valve element 50 toward the piston 16. During high temperature operation, the shape memory alloy compression spring 53 retrieves its memory shape so that the valve element 50 blocks the communication hole 15c to hydraulically lock a cylinder chamber 15b in order to decrease the stroke of the piston 16. During low temperature operation, the bias compression spring 52 compresses the shape memory alloy compression spring 53 so as to move the valve element 50 toward the piston, and accordingly, the communication hole 15c is opened to increase the stroke of the piston 16.
