Abstract: PURPOSE:To make crash destruction progress by providing a wedge means including a main layer extending along the whole length of a FRP cylindrical main body and a partial payer inside the main layer integrally therewith for causing a joint to apply an axial direction compressing load between the main layer and the partial layer and to peel these. CONSTITUTION:When an axial direction compressing load is applied to a propeller shaft, a joint 2 is pushed to a main body 1 side, a wedge 2d is pushed in between a main layer la and a partial layer 1b and a spreading distortion of a circumferential direction is generated on the main layer 1a by the function of the wedge Since spreading destruction expansion for the main layer 1a is smaller than that for the partial layer 1b, only the main layer 1a is destroyed and inter-layer peeling between the main layer 1a and the partial layer lb occurs. The destruction of the main layer 1a is greatly advanced by a projecting part 2c. However, no destruction occurs on the partial layer lb connected to the joint 2 and this moves in an axial direction in the main body 1 together with the joint 2 while destroying the main layer 1a. Thus, satisfying such basic requirements as strength, the number of dangerous revolutions and the like, destruction is surely progressed while matching the destruction of a body at the time of crash.

Title: Two-wire type contactless switch
Inventor: YAMASAKI TAKAO
IPC: H03K17/945
Filed: 1991-11-11
Abstract: PURPOSE:To prevent malfunction when a load current is decreased by inputting a detection signal of a sensor circuit to each transistor(TR) for load switching and operation display via an output control circuit. CONSTITUTION:When a resistance of a load 2 is large and a load current is small, a voltage between terminals a, b is decreased and when it decreases down to a 2nd threshold level of an output control circuit 4, a base current of a load switching TR 11 from terminal (f) is decreased, a resistance between the collector and emitter is increased to keep the input voltage of a constant voltage circuit 5 at a 2nd threshold level. When the resistance of the load 2 is further increased and even when the collector and emitter of the TR 11 are completely turned off, the voltage between the terminals a, b is decreased and when it decreases down to a threshold level of the circuit 4, a base current of the operation display TR 10 from the terminal (e) of the circuit 4 is reduced and the resistance between the collector and emitter is increased to keep the voltage between the terminals a, b at a threshold level. Thus, it continues until just before the required minimum lighting current of the light emitting element 8 cannot be kept. Thus, malfunction is prevented.

Title: Output circuit
Inventor: KUMANO MASAHIRO
IPC: H03F1/32
Filed: 1985-12-26
Abstract: PURPOSE:To supply a high frequency large output signal to the circuit of the next stage without distortion by adding a new variable current source so as to flow a required quantity of current as required in order not to increase the current of a constant current source remarkably. CONSTITUTION:An emitter 3 of a transistor (TR) 1 of an output circuit is provided with the 2nd current source 7 in addition to the 1st current source 4. The 2nd current source 7 should be a source known as a variable current source absorbing a large current Ix when an input signal impressed to a base 2 of the output TR 1 is deviated largely negatively. Since the correlation between an input signal fed to the base 2 and the current Ix of the 2nd current source 7 is as shown in figure, the power consumption is reduced in comparison with the drive by a constant current source and the distortion at a high frequency and large signal is less.

Abstract: PURPOSE:To secure safety while a stepping motor is not excited by connecting a control valve as a rotary type flow control valve to the shaft of a stepping motor, and providing a stopper for stopping the valve body in a position where the valve body is closed up, and providing a return spring for rotating the valve body in its closing direction. CONSTITUTION:When a valve body 16 is rotated clockwise through about 90 degrees with a control valve 5 full open, a throttling piece 18 blocks an outlet port 15 and an abutting piece 22 collides with a stopper 23. In accordance with the number of pulse signals of an exiting current sent from an electronic control device 6 to a stepping motor 4, the area of the passage of the outlet port 15 is varied by the throttling piece 18 to control the amount of air so as to maintain the idling speed of an engine at a predetermined value. In the event that the exiting current is cut off because of trouble with the control device 6 and the stepping motor 4 as the control valve 5 is opened, the valve body 16 is rotated clockwise by a return spring 21 having both ends stuck to the stopper 23 and the valve body 16 so that the throttling piece 18 blocks the outlet port 15. Therefore, only the air of a throttle valve 2 is supplied to the engine and so the speed of the engine is not heightened.
