Inventor: SAKANO YOSHIKAZU
IPC: B41J2/14
Filed: 1987-11-24
Abstract: PURPOSE:To make high density and fully multiple, by a method wherein one side electrode is extended to an end part of one side main face of a substrate, and a resistor established to the other main face of the substrate and the extended electrode are electrically connected by a common electrode. CONSTITUTION:Electrodes on one side among electrodes connected to an electrothermal conversion material are respectively extended to an end part of a substrate to form a common electrode 203. Besides, a resistor 201 as a radiator 205 arranged on the other side face of the substrate is extensively electrically connected to the electrode 203 at an edge face of the substrate with a joint electrode 206. Since the radiator 205 has a short-circuit-function and a function that accumulated heat is radiated from the substrate 204, it is settled only to keep electrode density on the substrate equal to arrangement density of the electrothermal conversion material. Therefore, two times density of heating resistant array can be obtained by traditional packaging density, and said resistance can be reduced to an extent capable of being neglected by connecting the common electrode to a substrate radiation means. Wiring resistance can be decreased to one half traditional one or less, and driving becomes easy.

Filed: 1989-11-13
Abstract: PURPOSE:To increase the internal clock speed by generating a double high frequency clock signal in a frequency doubler block and doubling the resulting signal in order by a similar frequency doubler block. CONSTITUTION:n-Stages of frequency doubler blocks 5 each including a clock signal of a double frequency are provided and when a selective signal E is at the m-th stage, a multiplexer 4 outputs the output of the m-th stage of the frequency doubling block 5. As a result, a clock signal F of a frequency at a multiple of 2<m> of an input clock signal frequency is outputted to an output terminal 7 of the multiplexer 4, where the relation of 1<=m<=n exists. That is, the clock of a frequency as a multiple of 2<1>-2<n> is generated, and a frequency of the m-th (1<=m<=n) clock signal is outputted as a frequency of a multiple of 2<m>. Thus, a high speed clock signal is obtained internally without generating a high speed clock externally.

Title: X-ray gun
Inventor: KONISHI YASUO
IPC: H01J35/08
Filed: 1989-11-14
Abstract: PURPOSE:To provide an X-ray gun capable of restricting the scope of an electron beam on an anode surface sufficiently small and free from contamination of the anode due to evaporated substance from a filament by disposing a repeller electrode in an electro-optical system for converging electrons emitted from the filament onto the anode surface which repeller electrode is for deflecting the electron beam. CONSTITUTION:A repeller electrode 6 placed behind a second grounding electrode 4 is of a cup shape with an electrode emission opening 61 made at a location off the center of the bottom thereof. An anode 5 is placed behind the opening 61. A negative voltage of several hundred volts is applied to the repeller electrode 6. Therefore, an electron beam (e) which has passed from a filament 1 through the second grounding electrode 4 is repelled by the repeller electrode 6 with its locus bent and led through the electron emitting opening 61 to converge on the surface of the anode 5. Since the evaporated substance C emitted out of the filament 1 travels in a straight line, the substance C strikes the bottom surface of the repeller electrode 6 and cannot fall onto the anode 5. This provides a minute X-ray source to provide an X-ray gun free from the anode contamination due to the filament evaporation substance C.

Title: Apparatus and method for controlling rotation
Inventor: IMAMURA TADASHI
IPC: H02P29/00
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce rotational speed change and to realize an accurate rotational speed by detecting a frequency difference between a detection pulse train and a reference pulse train, detecting a phase difference between a detection pulse and a reference pulse, and increasing or decreasing a rotational speed of a rotary drive source, based on the detected frequency difference and phase difference. SOLUTION: A frequency difference detector 4 detects a frequency difference between a detection pulse output from a sensor S and a reference pulse train, and a phase difference detector 3 detects a phase difference between the detected pulse and a reference pulse. The rotational speed of a DC electric motor 9 is increased or decreased by a charge pump circuit 5 of a rotational speed increasing or decreasing means, low-pass filter 6 and a PWM circuit 7, based on its frequency difference and its phase difference. Thus, a rotational speed change can be reduced, without depending upon a flywheel. Even in the case of using a traction reduction gear having unfixed reduction gear ratio, the rotational speed of a rotor is used as a feedback signal, and hence accurate rotational speed can be realized.

Title: Power steering device
Inventor: MORI YUTAKA
IPC: B62D6/00
Filed: 1985-12-26
Abstract: PURPOSE:To facilitate such operation of a motor vehicle as backward movement and oblique backward movement, by relatively heightening a sensitivity which is the ratio of a steering assistant force to manual torque, when the vehicle is in the state of backward movement, to lighten the operation of the steering wheel thereof in that state. CONSTITUTION:During the drive of a vehicle, control coefficients alphaA, betaA, gammaA corresponding to the speed of the vehicle, the angle of steering thereof and the angular velocity of the steering are determined in a CPU 61 in accordance with a characteristic map stored in a ROM 63. It is judged from the sign of the quantity of the vehicle speed whether or not the vehicle is in the state of backward movement. When it is judged that the vehicle is in the state of backward movement (or forward movement), an electrical current control coefficient R (F:R<F) for the backward movement (or forward movement) is read as a variable M. A driving current IOA is calculated according to a formula IOA=MXalphaAXbetaAXgammaA to obtain a control signal which is applied to a flow rate control valve 40 through a solenoid drive circuit 75. The flow rate of discharge from a pump 22 is thus increased so that a sensitivity for a steering assistant force caused by a power cylinder 15 is made higher than that in the forward movement of the vehicle.

Title: Input device
Inventor: TAMURA SHINICHI
IPC: G06F3/038
Filed: 1990-10-31
Abstract: PURPOSE:To improve the operability and the operating speed of an input device and also to reduce the operating fatigue of an operator by operating a pulse changeover switch to output pulses twice the ordinary number of pulses when the input of a large number of pulses is desired by the operator. CONSTITUTION:An X pulse doubling circuit 8 and a Y pulse doubling circuit 9 produce two short pulses at the rise and the fall of the pulse produced by an X sensor 6 or a Y sensor 7 in order to obtain the double pulses. A switch to changeover the number of output pulses is turned on and then an X gate circuit 10 and a Y gate circuit 11 transmit the outputs of both circuits 8 and 9 as the X and Y sensor outputs 15 and 16 respectively. Thus the double pulses are outputted. As a result, the number of pulses are doubled and an input operation is facilitated with an input device when a large number of pulses are required.

Title: Dual-port memory
Inventor: SUGITA MITSURU
IPC: G11C11/41
Filed: 1990-10-31
Abstract: PURPOSE:To easily set the timing of the dual-port memory and, at the same time, to minimize the timing margin by arranging the decoders, selectors, and sense amplifiers of both ports at the same location. CONSTITUTION:Mask patterns of the sense amplifiers and selectors 3 and 4, y-decoders 5 and 6, and x-decoders 7 and 8 of ports A and B are arranged at the same location. Since the difference in wiring length for control signals becomes negligible between the ports A and B, the time lag between the control signals becomes smaller and, in addition, no difference is produced in delay time by the differences in lengths between word lines and between bit lines even when any one of memory cells is selected. Therefore, the timing of the control signals can be easily designed and, at the same time, the timing margin can be reduced.
