Title: Display device
Inventor: FUKUSHIMA HIROMI
IPC: H01L33/00
Filed: 1994-11-14
Abstract: PURPOSE: To improve a luminance characteristic and durability, to prevent an erroneous lighting and to miniaturize a device in the display device of light emitting diodes driven with an AC voltage. CONSTITUTION: Respective light emitting parts 1a, 1b of a first and a second light emitting parts in which plural light emitting diodes are connected in series are connected in parallel so as to reversely biased each other and a protective circuit 2 in which a resistor and a capacitor are connected in series is connected to the parallelly connected light emitting parts in series and the AC voltage is impressed on them. The luminance of display lamps are improved and the reverse breakdown voltage of light emitting diodes is prevented from impressing by making either the first or the light emitting parts 1a, 1b emit lights even in the case of either positive voltage or the negative voltage of the AC voltage.  Since the instantaneous power of the resistor is set to be low by the capacitor of the protective circuit 2 by lowering the AC voltage to a forward voltage required for light emitting of plural light emitting diodes connected in series with the resistor of the protective circuit 2, the resistor is miniaturized.

Filed: 1986-12-22
Abstract: PURPOSE:To obtain a high frequency amplifier device having a sufficiently high drain-source voltage by connecting in series one piece of plural pieces of diodes so that a current flows in the forward direction, between a source of an FET and a ground. CONSTITUTION:A diode 15 for level shift is connected between the source of the FET 1 of a GaAs dual gate and the ground. To a first gate of the FET 1, a bias corresponding to a potential difference across a resistance 4 is impressed, and it is in an optimum use state. At the time of controlling the gain, the potential VAGC of a second gate of the FET 1 is lowered, but the potential of a point 16 is nearly constant by the forward voltage of the diode 15 for level, irrespective of the variation of the drain current of the FET 1. Accordingly, the potential of the point 16 can be set to the lowest potential by which the FET 1 executes pinch-off at the time of the potential VAGC=0 of the second gate, and even by a low voltage power source, a sufficiently high drain-source voltage is obtained. In such a way, a high frequency amplifier for obtaining a high output by a low voltage power source is obtained.

Title: Semiflash ad converter
Inventor: TAKAIWA KAN
IPC: H03M1/36
Filed: 1988-12-02
Abstract: PURPOSE:To attain no-linear A/D conversion by polygonal line approximation by using a linear D/A converter and a non-linear A/D converter and correcting relation between a quantization error to be generated in the former and the input range of a second A/D converter. CONSTITUTION:A non-linear A/D converter (ADC)7 outputs a digital signal, which is proportional to the 0.45th power of an input signal, and a non-linear D/A converter (DAC)8 outputs an analog signal to be proportional to the 2.2nd power of the input signal. Accordingly, the signal to be proportional to the input signal of the ADC7 is outputted from the DAC8. A reference voltage generating circuit 9 changes a reference voltage VREF of a second ADC5 in correspondence to the output signal of the ADC7. Thus, since the relation between the quantization error to be generated in the ADC7 and the ADC5 is fixed and the A/D conversion can be suitably executed regardless of the size of the input signal. The A/D conversion by 16 polygonal line approximation can be executed by a semiflash ADC.

IPC: H04N9/44
Filed: 1989-11-28
Abstract: PURPOSE:To always synchronize an external synchronizing signal without being effected with ambient environment as temperature or the like by generating a continuous signal synchronously with a color synchronizing signal from a burst color synchronizing signal separated from an output video signal, comparing the phases and applying synchronizing control of the output video signal. CONSTITUTION:A phase difference between a color synchronizing signal separated from an output video signal from a burst separation circuit 38 and a chrominance subcarrier delayed from a delay circuit 24 is always made zero by controlling the delay of a delay circuit 24 so as to make the signal delay caused in a phase shift circuit 31 to a line driver 37 the same as the delay of the delay circuit 24 at all times. Thus, an output video signal having a color synchronizing signal synchronously with the horizontal synchronizing signal of an external synchronizing signal and whose phase is coincident with the color synchronizing signal of the external synchronizing signal is obtained.

Abstract: PURPOSE:To secure such a printing recorder that is compact in size by transferring an image pattern being latensified in a recording material through heat out of a heating element, on an image receiving sheet of paper and developing and fixing it. CONSTITUTION:Since an original image pattern read by an exposure means 12 is merely performable with a photosensitive-thermosensible method alone, without requiring any pressure work, when it is transferred, the extent of pressing force in a developing means 18 can be set to smallness. In addition, since there are provided a gap holding means 20, holding a gap between the exposure means 12 and a recording material 1 at a specified space at all times, and a tension imparting means 30 giving constant tension to this recording material 1, improvement in development quality is well promoted. With this constitution, miniaturization and lightweightiness are promoted in addition to the development quality.

Title: Multi-cpu system
Inventor: MUKAI ATSUSHI
IPC: G06F15/16
Filed: 1989-11-28
Abstract: PURPOSE:To always use a data bus in its active state by adding an arbitration circuit to a CPU module containing a CPU, a local memory, and a common memory and connecting the CPU to the common memory only at the time of an access request. CONSTITUTION:A common memory 13B, etc., of each CPU module 1A, etc., usually undergoes the DMA control via a multi-CPU module and a system bus 6, and data are successively sent to the common memories of the subsequent CPU modules. Meanwhile a CPU 10 has an access to a local memory 13A. When the CPU 10 gives a write access request to an arbitration circuit 22 for the memory 13B, the circuit 22 inactivates a DMA acknowledge signal DMAACK and a DMA grant signal DMARQ and separates the bus 6 of a data bus from the memory 13B and secures the connection between the memory 13B and a local bus. Thus the bus 6 requires no floating state and can always be kept active. Then the common memory is quickly rewritten.
