Title: Pyroelectric detector
Inventor: FUKUDA KATSUYOSHI
IPC: G01J5/14
Filed: 1982-11-29
Abstract: PURPOSE:To reduce pulse induction by inserting a grounded gate type field effect transistor (FET) circuit in the input side of an output FET. CONSTITUTION:When a positive pulse voltage 36 is applied to the drain 29 of the 2nd FET27, its drain current is used in the saturated state to the drain voltage, so there is no variation with the pulse. A voltage, however, is applied to the gate through a feedback capacitor Cos37. The drain current varies with the gate voltage, so the drain current of the FET27 is a positive pulse current. Consequently, a positive pulse voltage is generated as a signal, but the operation never become unstable. When a negative pulse voltage is applied, a forward voltage is developed between the drain 26 and gate 25 of an FET24 and charges accumulated in the feedback capacitor Cos37 and input capacitor Cis38 of the FET27 are neutralized speedily and the FET becomes durable to external induction of pulses, etc., without being cut off.

Title: Auto-zero setting method for measuring outside diameter of rotating object having surface of discontinuity
Inventor: AOKI KAZUHISA
IPC: G01B21/10
Filed: 1995-08-17
Abstract: PROBLEM TO BE SOLVED: To automatically perform a zero setting by using a master having a surface of discontinuity which is resemble to that of an object to be measured even when the number of teeth of a gear is an odd number by providing several processes between a master setting process and correction value setting process. SOLUTION: A master 100 is set and probes 11 and 12 are positioned on nearly opposite sides of the rotating shaft of the master 100. When the master 100 is steadily rotated, the time required by the master 10 for rotating by the angle corresponding to the pitch of the discontinuous surfaces of the master 100 is inputted to a computer 30. The computer 30 reads the maximum value in each sampling period through A/D converters 22 and 23 and calculates correction values and registers 41 and 42 respectively output the correction values. The values written in the registers 41 and 42 are inputted to auto-zero circuits 18 and 19. When the values are inputted to the circuits 18 and 19, auto-zero setting operations are completed, because the maximum values held by sample hold circuits 20 and 21 are adjusted to prescribed values when the master 100 is set.

Title: Instrument with drawer-ejector of recording medium
Inventor: MANFUREETO KAMERAA
IPC: G11B15/675
Filed: 1988-08-25
Abstract: PURPOSE: To make an appliance compact and space less by constituting this appliance in such a manner that a cassette is transported to the prescribed position in the appliance by an extractor and is again brought to a take-out position by tracking the reverse moving route. CONSTITUTION: The cassette 11 glides on a steeply sloping part 15 to arrive at the prescribed position and the extractor 2 is transported together with the cassette 11 until the cassette 11 is captured by the adhesive friction of revolving rollers 8, 9 at the time of mounting. The cassette 11 is then retracted into the appliance faster than the motion of the extractor 2. The extractor 2 pushes the cassette 11 with its corner part 17 until the cassette 11 attains the perfect insertion sate. The taking out of the cassette is executed by the stages reverse, one by one, from the mounting stages up to the take-out position corresponding to start position. Then, the travel that the extractor 2 passes at the time of mounting or taking-out is much smaller than the travel of the cassette 11. As a result, the saving of the space is made possible.

The scanning of bar codes on a slip is identified by the scanner 24 and incorporated in a device 28 to record a slip number. Next, bar cord input is stopped and the load 10 is carried out to a next-step conveyor 16B. The load 10 on the conveyor 16B is moved, but when a sensor 18B set up corresponding thereto detects the load 10, the conveyor 16B is stopped. In this way, recorded data of the slip number stored formerly and a parting signal code are input to the register 34.

IPC: B66F3/26
Filed: 1989-08-16
Abstract: PURPOSE:To prevent the interference between the lower edge of a plunger and the inner surface of a cylinder by forming the projections which project from a plunger diameter at two places at the lower edge of the plunger and using the projections as stoppers and contracting the inside diameter of the cylinder by the plunger projection portion and suppressing the compression and expansion of the working oil. CONSTITUTION:In order to prevent the slip-off of a plunger 5 onto the outer periphery at the lower edge, a stopper 14 is installed, and the dimension of the stopper 14 is made equal to the conventional flange diameter and the lateral width B is set to the min. dimension as stopper. Therefore, two kinds of plays are generated between the stopper 14 and the inner surface of a cylinder 10, and the dimension of the stopper 1 can be reduced to the allowable min. limit, and the inside diameter D of the cylinder 10 can be reduced to the tangential line for the plunger, and also the working oil quantity can be reduced. When each interference is generated because of the eccentricity and curvature of the cylinder 10 and the plunger 5 due to the installation error of a hydraulic jack 4, a gap G3 is generated by shifting the direction of the projection 14 of the plunger 5 for the inner surface of the cylinder 10 by turning the plunger 5, and the vertical movement of the cage in getting-on/off operation is eliminated by suppressing the compression and expansion of the working oil, and the cage can be stopped.
