Title: Solid-state image pickup device
Inventor: IMAIDE TAKUYA
IPC: H04N5/335
Filed: 1985-04-05
Abstract: PURPOSE:To remarkably reduce noise compared with the conventional device by providing a means which transfers temporarily a signal charge from a horizontal signal line and a vertical signal line to a smaller capacity when the signal charge is read from a photoelectric converter. CONSTITUTION:One to several lines are selected in one horizontal scanning period and positive voltage is impressed on the output phim of the corresponding vertical shift register. After that, by impressing in order the positive voltage on the outputs psi1, psi2...psi4 of a horizontal shift register, rows are selected in order and a video signal is obtained. At a time tn, psin becomes the positive voltage and the signal charge on the corresponding photodiode 1 is read to a horizontal signal line capacity Ch. After that, bias with negative charge is sent form a Co to a Ch with setting a P1 at lower potential and also with returning the P1 to high voltage, the signal charge on the Ch is transferred to the small capacity Co with the bias. After that, with setting a P2 at high potential, a transistor 6 is conducted and the signal charge on the capacity Co is amplified by a pre-amplifier 7 and it is outputted in the shape of the voltage.

IPC: H03M9/00
Filed: 1981-05-12
Abstract: PURPOSE:To increase the processing efficiency of a microcomputer, by arranging an FIFO between a data bus and a serial I/O chip and taking the FIFO as a serial I/O buffer. CONSTITUTION:In a microcomputer having a CPU, a memory and a serial I/O a data entered in a serial I/O 2 is fetched to a reception FIFO buffer 5 at each reception data ready signal RXRDY and shifted. The RXRDY is turned on at each one byte reception and turned off with the data callout at the buffer 5. Thus, even while the CPU 1 makes a different processing, the next data is fetched to the buffer 5 and the result of processing of the CPU 1 can be transmitted to a transmission FIFO buffer 6 in the system processing speed. The data given to the buffer 6 is transmitted to the I/O2 with a transmission data ready signal TXRDY and a clock and outputted at each one byte. Thus, the CPU 1 can make processing continuously independently of external devices and the total processing time can be reduced.

Title: Time division multiplex signal communication system
Inventor: HORII YUTAKA
IPC: H04J3/00
Filed: 1981-05-13
Abstract: PURPOSE:To execute transmission efficiently even in case when the quantity of a data is varied incessantly, by providing a station discriminating code in a time division multiplex signal. CONSTITUTION:A time division signal is demodulated by a demodulator 1 and is outputted to a data line 10. When a synchronizing pattern detecting part 2 has received a synchronizing pattern in a time division multiplex signal, a synchronizing pattern detecting signal is sent out to a counting part 3. The counting part counts a variation of a clock signal which is initialized by this detecting signal and corresponds to length of the time division multiplex signal. As a result, since an end of a data becomes clear, its timing is informed to a station discriminating code deciding part 5. A shift register 4 converts the time division multiplex signal received in series, to parallel, and supplies it to the deciding part 5 and a register 6. The deciding part 5 is informed of the end part of a data from the counting part 3, decides it to be a data of its own station by detecting the coincidence of contents of the register 4 and the local number, and instructs to accumulate its data, to the register 6. The data accumulated in the register 6 is processed by a data processor.

Abstract: PURPOSE:To prevent the distortion from being caused to a waveform at the reproduc tion of a recording signal by inserting a conductive member of a nonmagnetic material between a main magnetic pole and a leg of an auxiliary magnetic pole in close contact with both. CONSTITUTION:In exciting strongly a coil 9, the main magnetic pole 6 and a magnetic layer 3 of high permeability of a recording medium 1 cause magnetic saturation, a bias magnetic path 8a from an opposed wall 6B of the main magnetic pole 6 toward a leg 7A of an auxiliary magnetic pole 7 directly and a bypass magnetic path 8b from the opposed wall 6B of the main magnetic pole 6 toward the magnetizing layer 3 of the recording medium 1 are generated so as to leave the magnetism in the horizon tal direction component other than the broadwise direction to the magnetizing layer 2. In this case, since the conductive member 11 made of a nonmagnetic material is inserted between the main magnetic pole 6 and the leg 7A of the auxiliary magnetic pole 7 connected thereto, the magnetic flux through the bypass magnetic path 8b causes an eddy current 12 in parallel with a face opposed to the wall 7c of the auxilia ry magnetic pole 7 to form the magnetic path 8c, the magnetic flux passing through the bypass magnetic path 8b is reduced remarkably by the eddy current loss and no distortion is caused in the waveform at the reproduction of the reproducing signal.
