Title: Control device for electric vehicle
Inventor: MIYASHITA ICHIROU
IPC: H02P27/08
Filed: 1981-08-31
Abstract: PURPOSE:To prevent the jump of an output current and a traction force at the time when switching is made by a speed range wherein a voltage control is conducted to a speed range in which a voltage becomes constant, by restricting a slip frequency temporarily at this time, and releasing it thereafter at a prescribed time constant. CONSTITUTION:An instruction converting circuit 10 resolves a motor torque instruction into a slip frequency instruction 102 and a primary current instruction 103. A slip frequency restricting circuit 12 generates a slip frequency instruction 112 containing a pattern which is restricted to a low level when the speed of the main motor 80 reaches a prescribed value and thereby a one-pulse mode signal 111 is given and which is returned thereafter to its original value at a prescribed time constant. A modulation circuit 60 receives a deviation signal 104 of the slip frequency instruction 112 from a motor speed signal 110 and a deviation signal 105 thereof from a primary current signal 109, and supplies an arc-igniting and arc-extinguishing signal 106.

Title: Paper feeder
Inventor: KAWAI YASUHIRO
IPC: B65H1/26
Filed: 1984-06-29
Abstract: PURPOSE:To simplify the construction of a cassette, reduce its size and weight and facilitate its handling, by making it possible that the position of at least one of a pair of cassette reception members provided on the frame of a paper feed section and having cassette reception grooves facing each other is changed in the direction of the width of the cassette. CONSTITUTION:When a paper feed cassette 3 is to be set in a paper feed section 2, the paer feed cassette is chosen depending on the size of a copy and the positions of both reception members 4, 5 are adjusted depending on the size. At that time, the operating member 71 of a locking means is turned counterclockwise to push down a clamping plate 7 to separate an elastic member 76 from the bottom of a frame 21 to unlock the reception member 4. The member 4 is then moved to a position corresponding to the size of the cassette 3. The operating member 71 is turned clockwise to pull up the clamping plate 7 to bring the elastic member 76 into pressure contact with the bottom of the frame 21 to lock the reception member 4 in a prescribed position. Since such paper feed cassettes are exclusively used for sizes of copies, respectively, an adjusting partition plate or the like does not need to be provided in each cassette. This results in simplifying the construction of each cassette, reducing its size and weight and facilitating its handling.

Title: Head positioning mechanism
Inventor: KANEKO REIZOU
IPC: F16F9/30
Filed: 1977-11-15
Abstract: PURPOSE:To rapidly attenuate the vibrations produced in carriage by filling magnetic fluids in the clearance between the carriage provided with heads and the fixing part. CONSTITUTION:A carriage 11 which is provided with heads 1... is supported by rolling bearings 3... and is moved in tracking positions along a stationary guide rail 13 by way of an actuator. Magnetic fluids 15, 15 which are prevented from flowing to the outside of the clearance by being attracted by permanent magnets 14, 14 buried in the rail 13 are filled in the narrow clearance between the top surface of the rail 13 and the opposing surface of the carriage 11. Hence, if the gravity during travel causes a change in the clearance between the carriage 11 and rail 13, the fluids 15, 15 are forced out or drawn in and this produces squeeze-out effect owing to viscosity, giving the attenuation force corresponding to the clearance changing speed to the carriage 11 and letting the vibrations attenuate rapidly. As a result, rapid and sure head tracking is effected.

Title: Rubber coupling
Inventor: TAKEMURA TOJI
IPC: F16D3/62
Filed: 1986-06-13
Abstract: PURPOSE:To obtain the torsional rigidity as desired, miniaturize the coupling, and to enlarge the scope of application, by imbedding an endless cord, which envelopes the parallel collars arranged in a circular form as the collars stand neighboring to each other, into a rubber material in such a manner that the collars corresponding to each other are in sagging. CONSTITUTION:Leaving out a central, bridged part 10 situated between collars 1 and 1 neighboring to each other, a rubber material 3 is provided with lightening hollow parts 11 and 11, which are situated between the collar 1 and the central, bridged part 10, and a pair of retaining plates 12 and 12, each of which faces to the sagging part of each endless cord 2. Both ends of these plates 12 are exposed to the corresponding, lightening hollow part 11 and are imbedded into the rubber material 3. In this case, one of the alternate collars is joined to one shaft, while the other one is joined to the other shaft by means of the bolt. Accordingly, the torsional rigidity as desired such that it is low for a small twist angle (range) but it is high for a large twist angle can be obtained. At the same time, since the size of the coupling can be reduced, we can take advantage of the merits in the strength of both bolts and bolt-joined part, thereby enlarging the scope of application of the coupling.

Title: Protective circuit for transistor amplifier
Inventor: OOTSUKI TAKASHI
IPC: H03F1/52
Filed: 1978-11-02
Abstract: PURPOSE:To secure an assured protection with a simple constitution by inserting the diode between the output middle point and the collector of the A-class amplifier transistor. CONSTITUTION:Under the normal condition, B voltage VB at the collector point of pre-driving transistor Tr7 of the A-class amplifier becomes as shown in the equation (where VA is the voltage at output middle point A and VBE is the base-emitter voltage of VBE). And diode D13 to be the protective circuit features the reverse bias state, and D13 does not affect the amplifier at all as long as the normal condition is kept. In case point A is shorted to the power source for some reason, the voltage at point A becomes VCC to be applied to the base of Tr5 of the other side  in differential amplifier circuit 1. Thus Tr5 is turned on, and accordingly inter-step  Tr6 and Tr7 are put forcedly under the conducting state. However, D13 conducts  immediately when point A is shorted, and 2nd driving Tr9 and 2nd output Tr11  become nonconductive. Thus an assured protection is attained.
