IPC: H02H7/12
Filed: 1990-01-31
Abstract: PURPOSE:To suppress an overcurrent and a surge voltage by a simple circuit by connecting an FET on the input side of a smoothing circuit and by fixing a gate-source voltage of the FET to be a prescribed voltage, in a switching regulator or the like. CONSTITUTION:In a power source protecting circuit 1, an FET 5 etc., are connected between a rectifying circuit 3 and a smoothing circuit 2. The source of the FET 5 is connected to a switching circuit 9, while the gate thereof is connected to the grounding line 4 through a Zener diode 8. Between the source and the gate of the FET 5 a shunt regulator 7 is connected. While making currents Ia and Ib flow when a power switch 13 is made, a gate-source voltage of the FET 5 is fixed to be a prescribed voltage by the shunt regulator 7. Accordingly, an output current Io of the FET 5 is controlled to be a constant current. Although an external surge voltage is impressed on the gate of the FET 5 through a resistor 6, it is absorbed by the Zener diode 8.

Title: Speed control system for motor
Inventor: IZUMI TETSUO
IPC: H02P7/292
Filed: 1981-02-20
Abstract: PURPOSE: To obtain the responsiveness and the stability in the desired control over all load range by regulating and calculating a current and a speed when a motor current is in continuous state and regulating and calculating only the speed when the motor current is in intermittent state.  
     CONSTITUTION: To apply a firing pulse of any thyristor in a thyristor converter 1, the firing signal generating time becomes a reference time for determining the next firing signal generating time. Next firing signal is generated at the time when a time obtained by correcting the interval of 60° from the reference time with a regulated and calculated result Δm n  at each time is elapsed. When the motor current is in continuous state, the current and the speed are regulated and calculated, while when the motor current is intermittent state, only the speed is regulated and calculated.

A score adding part 3 calculates the score of a section classified by the judging part 2 at every picture element and finds out the total score of all picture elements. An authenticity discriminating part 4 compares the score threshold of the data 1d with the total score found out by the adding part 3, and when the total score is more than the threshold, the part 4 judges the medium as a true bill.  When the total score is less than the threshold, the medium is judged as a false bill.

Title: Paper sheet carrier
Inventor: SHIMIZU SABURO
IPC: B65H5/06
Filed: 1989-02-03
Abstract: PURPOSE:To construct a paper sheet carrier that can be installed in the narrow space by using a guide member provided with projections in a carrying direction of a recording paper and a paper sheet, and one or more carrier roller provided on the opposite side of the projection. CONSTITUTION:A carrier roller 3 is narrower in the width than the space of installation of a projection 1, and is arranged between each projection.

When a recording paper P is inserted between the guide member 1 and a guide plate 5, it is pushed to the surface of the carrier roller 3 by means of the 'firmness' of the paper, and is carried by means of frictional power generated in the roller surface. This very simple structure of a guide member that has a projection and of a carrier roller, with small space occupancy, can be installed as a part of a carrying passage between a supply cassette and a photosensitive drum of a copier.

Abstract: PURPOSE:To prevent the generation of vibration while to accurately by fitting a valve rod slidably into a valve rotary shaft while fitting an operationg shaft rotatably in axial direction of the valve rotary shaft thereby sliding the valve rod through rotation of operating shaft. CONSTITUTION:In order to bring a valve to closed state, a valve rotary shaft 7 is rotated through a gear 8 to bring the valve body 1 to close position thus to rotate the double face section 13 while through gearing of pinion 4 and rack 3, the valve rod 2 and valve body 1 are moved along valve rod axis 10 toward a valve seat 6 to push the valve body 1 strongly against the valve seat 6 thus to block fluid reliably. While in order to bring the valve into open state, double face section 13 is rotated in reverse derection to move the valve body 1 slightly from the valve seat 6 thus to provide micro gap between them thereafter a rotary shaft 7 is rotated to move the valve body 1 by required angle. Consequently rotary torque is low and after moving by required angle the double face section 13 is rotated again to push the valve body 1 against the valve seat 6 and fix, resulting in elimination of vibration.

Filed: 1981-02-19
Abstract: PURPOSE:To obtain a flicker-free three-dimensional TV image by using a magnetic sheet memory, and outputting signals, delayed when a right-image and a left- image signal are absent, then projecting two fields of the same image each for the left and right image. CONSTITUTION:As the output signal of a video tape recorder 10, a right-image and a left-image signal are outputted, field by field, alternately in every. The right image is projected by connecting an electronic switch 14 to a terminal (b) during a right-image output period and by inputting the signal to a TV receiver 16. During this period, the image is recorded on a one-field magnetic sheet memory 11. Then, the switch 14 is changed over to a terminal (a) to output the image during a left-image output period. Consequently, the same image from the receiver 16 is projected on a CRT18 by two fields at every time without absence. The left image is the same. For this purpose, two deflecting plates 20 and 21 having different angles of deflection are arranged in front of CRTs 18 and 19, and the images are synthesized through a half-mirror to obtain a flicker- free three-dimensional image through deflecting eyeglasses 23 and 24 conforming with the deflecting plates.
