Abstract: PURPOSE:To prevent entering of cutting pieces or grinding powders to side of magnetic line, by a method wherein at cutting or grinding of a pole tooth in a stator, adjacent pole tooth portions of a plurality of magnetic poles are closed by a closing member. CONSTITUTION:At cutting or grinding of a pole tooth 16 in a stator 27, entering of cutting pieces or grinding powders to side of magnetic line 2 between adjacent pole tooth portions 17 can be prevented by a closing member 22 of resin 20.

Abstract: PURPOSE:To restrict a smear mixing in a signal, a pseudo-signal in a dark current and a noise of a fixed pattern by taking a differential of the first and the second signals obtained by conducting a horizontal switch element at a pulse timing and taking out the third signal. CONSTITUTION:An OY pulse is applied to a vertical gate line 3, two lines of image elements 1-1, 1-2..., 2-1, 2-2... are selected. For instance, when during a period t1, a signal of the image element 2-1, in an output out 6, an image signal S1, a noise by a smear, a noise by a dark current, and a fixed pattern noise are contained. During a period t2, the same image element 2-1 is selected again, and since the signal S1 is not accumulated, only noise is contained in an output out 7. Thereafter, the output of the out 6 is delayed by a time t1 by the use of a delay element 42. When taking a difference between the delayed output of the out 6 and the out 7 by using a differential amplifier 43, in an out 8, only a signal S1 having various noises removed is taken out.

Title: Variable relief mechanism for four-wheel steering
Inventor: HARAYOSHI MITSUHIKO
IPC: B62D7/14
Filed: 1992-09-18
Abstract: PURPOSE:To enable steering at low speed large steering angles and prevent rear wheels from being steered to large steering angles in the vicinity of the neutral position by controlling a relief valve by a piston, and providing the end face of a shaft, rotated according to a steering wheel angle, with a face cam to which a pin at one end of the piston is fitted so as to drive the piston according to rotation. CONSTITUTION:When a steering wheel is in the neutral position, the large diameter part of a cam 39 is on the left side, a poppet valve 35 is closed being brought into pressure contact with the valve seat 32 by a spring 36, and a piston 34 is at the left end. When the steering wheel is steered to the right, for instance, to rotate a shaft 43 clockwise, a shaft 37 is rotated counterclockwise, and the cam 39 is rotated. A cam groove 39a is constant in its radius during the time of a steering wheel angle being between 0 deg. and 230 deg., so that the piston 34 is not pressed to move. Upon exceeding 230 deg., the cam 39 presses a rod 34b and the piston 34 to move to the right so as to compress the spring 36. When the steering wheel angle reaches the maximum angle, relief pressure becomes the maximum pressure by the spring force of the spring 36.

Filed: 1984-11-27
Abstract: PURPOSE:To prevent the delayed return of a discharge valve after its opening by providing a valve guard portion brought into contact with the free end of the discharge valve with a back pressure hole communicating with the penetrated hole of the valve guard. CONSTITUTION:A valve guard portion 14 brought into contact with the free end 13a of a discharge valve is provided with a back pressure hole 18 communicating with a penetrated hole 14a of the valve guard 14 which has connection with a discharge path.

Abstract: PURPOSE: To set up a limit switch at the outside before its installation by installing such a unit as having both of a movable side stopper and this overrun detecting limit switch almost on the same radius, in a member being rotatable with a shaft center as the center. CONSTITUTION: When a robot body rotates with a turning shaft as the center and goes beyond the specified operating range, a lower side part 12a (or 12b) of a unit lever 12 installed in a movable member 14 comes into contact with a fixed side stopper 6 installed in a robot base 2, and thereby this lever 12 rotates in an arrow direction. With this rotation, any contact between an overrun detecting limit switch 8 of a unit and the lever 12 is taken off, detecting an overrun in the robot body, and a power supply to this body rotative driving part is cut off. Subsequently, a side face 12c (or 12d) at the limit switch side of the lever 12 hits on a working face 13a (or 13b) of a housing 13 in the unit, thereby mechanically stopping a rotation of the movable member.
