Title: Air-spring type hydraulic shock absorber
Inventor: KOBAYASHI TERUO
IPC: F16F9/08
Filed: 1982-09-30
Abstract: PURPOSE:To permit a bottomed load in a large capacity to be absorbed and softened by installing an annular shock absorbing member having an inside diameter larger than a piston rod, at the opening edge of a cylinder, and increasing the pressure receiving effective diameter by setting said annular member attached onto the housing of the piston rod when said member is completely bent. CONSTITUTION:A bump stop 41 for preventing bottoming during perfect bending is installed at the opening edge at one edge of a cylinder 21 in an air spring shock absorber 20, and the inside diameter D is made larger than the outside diameter (d) of a piston rod 26. Therefore, the effective diameter for receiving the bottomed load of the bump stop 41 is increased, and the load absorbing capacity is increased to burden the bottomed load in a large capacity. Since the bump stop 41 is brought into contact springily to a housing support 30 when the bump stop 41 is bent completely, a special member for receiving the bump stop 41 is made unnecessary, and the necessary number of parts can be reduced, and the total length of the shock absorber 20 can be advantageously reduced without varying the stroke of a piston 24.

IPC: G11B7/09
Filed: 1982-09-30
Abstract: PURPOSE:To realize a stable and sufficient eccentric follow-up property by providing the first photodetector for obtaining a track shift signal and the second photodetector for detecting a moving portion of a reflected light beam, in accordance with a prescribed arrangement, and correcting a signal of the first photodetector by a signal from the second photodetector.

Accordingly, a moving portion of the beam is mixed in a track shift signal (A-B) from the first photodetector 5. On the other hand, a signal (C-E/C+E) corresponding to the moving portion of the beam is obtained by the second photodetector 6, therefore, a correct track shift signal can be obtained by compensating the signal (A-B) from the first photodetector 5 by use of this signal.

Title: Current mirror circuit
Inventor: ISHII HIDEKAZU
IPC: H03F3/343
Filed: 1981-10-28
Abstract: PURPOSE:To avoid a load at an output terminal from giving effect on other output terminals, by connecting a resistor to a base of each transistor (TR) in a current mirror circuit. CONSTITUTION:Values of resistors 10-12 are respectively selected inversely proportional to the effective emitter area of the 1st TR1 and the 1st and 2nd output TRs 3, 5. In selecting the resistance values like this, a current which is equal to a current supplied to an input terminal 2 or proportional to the current in normal operation is picked up from the 1st and 2nd output terminals 4, 6. Even if a load connected to the 1st output terminal 4 is excessive, the base current of the 1st output TR3 is not increased by the resistor 11 and a current flowing to the 2nd output TR5 is unchanged. Thus, no effect is imposed on a current picked up from the 2nd output terminal 6.

Title: Lens shifting device
Inventor: TOYODA YASUHIRO
IPC: G02B27/64
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To surely shift a lens in a perpendicular direction to an optical without backlash in an optical axis direction by providing an elastic member generating pressing force for holding 1st and 2nd balls. SOLUTION: The lens 9 is supported in parallel with a reference plane perpendicular to the optical axis where a movable frame unit 8u is provided in a supporting frame 1 by the appropriate pressing of the elastic member 18 in the optical axis direction through ball groups (steel ball) 2 and 6 and a guiding member 4 without backlash in the optical axis direction, so that it is shifted on the plane perpendicular to the optical axis. Thus, the deterioration of optical performance caused by the tilt to the optical axis and the backlash in the optical axis direction is hardly caused. Since rolling friction by the balls (steel ball) 2 and 6 having smaller resistance than frictional resistance by the sliding of a shaft and a bearing is used, shift driving force by electromagnetic driving is made weak. Since the rotation of a movable frame 8 around the optical axis is prevented by the member 4 without using restoring force by a spring member, the load from the spring member is not exerted on the unit 8u at the time of shifting, and the shift driving force by the electromagnetic driving is made weak.

Abstract: PROBLEM TO BE SOLVED: To permit a control characteristic to bear no relation to a temperature operation and a deterioration phenomenon by controlling a loop gain by excessively vibrating the actual value of a controlled variable so that it exceeds a target value by a prescribed common difference. SOLUTION: The loop gain A of a control circuit 1 is equal to the product of the transfer functions of a target value comparison means 11, a control amplifier 12A and a control section 12B and it is controlled by the change of the amplification degree of the control amplifier 12A. The comparator 20 of an amplification degree controller 2 generates a controlled variable (a) equivalent to the code of a difference between an inputted common difference value (m) and a control deviation quantity (d). An operation device 21 controlling the control amplifier 12A is constituted as an integrator stage, for example, and it generates an amplification degree controlled variable (v) required for the amplification degree of the control amplifier 12A from the controlled variable (a).  The amplification degree controller 2 is active in a specified evaluation window for evaluating the control deviation quantity (d) by a trigger signal sync and only the excess vibration of the controlled variable (x), which is caused by the positive jump of command quantity (w) is evaluated for controlling the loop gain A.

Title: Weight detector
Inventor: INOUE MASANOBU
IPC: G01G7/06
Filed: 1987-07-13
Abstract: PURPOSE:To reduce a detection error by making a contact area between a supporting rotary shaft and an elastic body smaller than the sectional area of a shaft center part. CONSTITUTION:The weight of food laced on a placing base 5 is transmitted to a weight detecting means 8 through the elastic body 7 as the displacement of the thrust-directional stroke of the supporting rotary shaft 6. Here, the contact area of the rotary shaft 6 for the elastic body 7 is made smaller than the center sectional area of the rotary shaft 6. Consequently, when the food is placed on the base 5 and the rotary shaft 6 makes one turn, the amplitude of stress variation applied to the detecting means 8 is improved to about 1/4 as large as when the contact area is equal to the center sectional area of the rotary shaft 6. Here, a weight detected value is proportional to the stress, so variance in measured value due to rotation is reduced to about 1/4. Thus, the detection error is made small.
