Title: Deflection device for inline type color picture tube
Inventor: SHIYOUJI YOSHIKANE
IPC: H01J29/76
Filed: 1989-08-30
Abstract: PURPOSE:To make it possible to compensate green droop VGD generated at four corner parts of a face plate and obtain good convergence characteristics by supplying a current obtained by rectifying a horizontal deflection current by a rectifying circuit to second compensation coils. CONSTITUTION:A pair of second compensation coils 22 are connected with a horizontal deflection coil 36 through a rectifying circuit 23, and the second compensation coils 22 are serially connected with a pair of saturable coils 43a, 43b of a saturable reactor 24. Magnetic fluxes of opposite phases to each other are generated at the coil part of one horizontal saturable coil and the coil part of the other horizontal saturable coil of a saturable core 42 by vertical deflection current supplied to a vertical saturable coil 44 connected with a vertical deflection coil 34, so the current through the second compensation coils 22 are changed to be synchronous with the vertical deflection current. The vertical deflection quantity of a center beam is increased corresponding to horizontal deflection, so VGD is compensated. The convergence can thus be good for the whole range of a face plate.

Title: Torque limiter and paper feeder using it and business machine
Inventor: UMEDA ARAO
IPC: B65H3/52
Filed: 1994-09-20
Abstract: PURPOSE: To prevent transmission of torque not less than a constant value without using a coil spring. CONSTITUTION: When a motive power outputting member 3 (a housing member 6) is fitted around a motive power inputting member 2 (a friction member 5), the free end side of the housing member 6 is push-opened, and its inside diameter becomes almost the same diameter with the fixed end side. At this time, the housing member 6 fastens the friction member 5, and this fastening force generates transmission torque as frictional force between the housing member 6 and the friction member 5. When brake force acts on the housing member 6 by force exceeding the transmission torque by this friction, a slip is caused between the friction member 5 and the housing member 6, and transmission of torque is cut off.

Abstract: PURPOSE: To output a plurality of sounds with one operational amplifier and to facilitate an integrated circuit structure without any special mixing circuit by constructing a waveform generating D/A converter with a plurality of rudder resistor sets and one operational amplifier. CONSTITUTION: Data of respective amplitude value memory are respectively transmitted to amplitude D/A converters 1 and 3, and the maximum value of an amplitude voltage of the waveform is inputted into a reference voltage of a current-voltage conversion type waveform generating D/A converters 2 and 4 by a R-2R rudder resistor. The output of these two rudder resistors are connected at the input terminal of the ope-amplifier 5 to perform current mixing. That is, a point A where the output of two rudders resistances are connected is inputted into a minus input of the operational amplifier 5, when a feedback is performed with the resistance of KR, the potential of the point A is made to equal to the potential of plus input of the operational amplifier 5.  Therefore, currents flowing from respective waveform rudder are superposed as a minus terminal input current of the operational amplifier 5, and made to appear at the output terminal of the ope-amplifier 5 as an output voltage mixed respective waveforms.

Title: Optional waveform generator
Inventor: IKEGAMI TAKETOSHI
IPC: G06F1/02
Filed: 1989-08-31
Abstract: PURPOSE:To improve the resolution of an output waveform over the resolution of a DA converter by storing errors between arithmetic results and DA input data which are less than minimum resolution and determining DA input data by an arithmetic control circuit so that the stored errors are less than a half as large as the value of a minimum bit at all times. CONSTITUTION:The arithmetic control circuit 10 finds waveform data according to a waveform definition expression. The arithmetic result is converted into data D consisting of a number N of bits for the DA converter 3 (provided that N<M). Then E=M-D is calculated and a next storage error is further found. Here, EX=E(X-1)+E, where EX is a current stored error and E(X-1) is a last one. When Ex is judged and EX<=-1/2LSB, +1 is added to D and EX to obtain new values. Here, LSB is the value of the minimum bit of the DA converter. When +1/2LSB<=EX, -1 is added to D and EX to obtain new values. Said operation is repeated to obtain high-resolution waveform data.

Abstract: PURPOSE:To make it possible to forum thin film transistors (TFTs) having uniform characteristics on a glass substrate by a method wherein a local induction heating is used for an annealing of a non-single crystal semiconductor layer on the large-area glass substrate for low temperature use. CONSTITUTION:A film consisting of a high-melting point metal, such as Ni, Ta, W, Mo, Fe, Co and Cr, or its silicide, carbon or the like is selectively applied on TFT formation parts 1-3 in a non-single crystal semiconductor layer 1-2 grown on a glass substrate 1-1 for low temperature use to perform an induction heating using a high-frequency current, whereby an annealing is locally performed only on the TFT formation parts 1-3 in the layer 1-2 on the large- area glass substrate 1-1. As a result, the whole glass substrate 1-1 is not heated and the heating is limited locally. Accordingly, the glass substrate for low temperature use can be used as a substrate. Thereby, TFTs having uniform characteristics can be formed on the glass substrate 1-1.

Title: Manufacture of varistor
Inventor: NAKAYAMA AKIYOSHI
IPC: H01C7/10
Filed: 1989-08-31
Abstract: PURPOSE:To improve a nonlinear coefficient in a high-current region and to make it possible to improve surge breakdown strength to a large extent by adding a metal oxide as the raw material for a secondary component into ZnO which is the raw material of a main component, performing temporary baking and crushing at least twice, and baking the obtained molded body of the mixed raw materials. CONSTITUTION:At least one kind of metal oxide as the raw material for a secondary component is added into ZnO which is the raw material of a main component. Thereafter, temporary baking and crushing are performed at least twice. The obtained molded body of the mixed raw materials is baked. Since the temporary baking and the crushing are performed twice, the dispersing property of the raw material of the secondary component can be improved. Since defective parts are not present in a varistor, a nonlinear coefficient in a high-current region can be improved, and surge breakdown strength can be improved to a large extent. Since the occurrence of the concentration of currents can be prevented, breakdown of ceramics whose main component is ZnO and the short circuits between electrodes can be prevented.

Abstract: PURPOSE:To simplify constitution, to make the production inexpensive and to make an abrasion extremely small by abutting a thrust bearing member on the projection part of a clamp member and forming both members with a synthertic resin. CONSTITUTION:On the top of the clamp member 25 the projection part 53 is formed on which the clamp member pressing face part 55a of the thrust bearing member 55 is made to abut.
