Title: Wide band transmission system
Inventor: YAMADA KUNIHIRO
IPC: H04B3/00
Filed: 1983-03-11
Abstract: PURPOSE:To extend the sevice area in a small-scale network without requiring an equalizing amplifier by converting the first carrier frequency, which is received from a node, to the second carrier frequency in a head end so that the sum of these first and second carrier frequencies becomes a prescribed value when plural nodes use a be-directional transmission commonly. CONSTITUTION:In case of the transmission of a wide band signal form a node N 29 to a node N 53, the carrier of an inbound frequency f I is modulated with a data signal to be transmitted by a transmitter of the N 29 and is transmitted to a head end 10. A duplex filter 14 of the head end 10 outputs this received signal f I to a terminal L. A frequency converter 16 converts the frequency f I of the inputted inbound signal to a frequency fO of an outbound signal and outputs it from an output terminal OUT. The deplex filter 14 receives this outbound signal by a terminal H and transmits it to a cable C1. This signal is received by the N 53. For the purpose of performing this frequency conversion, the frequency converter 16 performs the converting operation in accordance with equation fO=fS-fI. In the equation, fS is prescribed constant value.

Abstract: PURPOSE:To attain the recording and reproduction of a picture at high speed and with miniaturized size, by providing a means for emitting a light emitting diode array with an external electric signal and a means for outputting an electric signal corresponding to the light received by a light emitting diode. CONSTITUTION:In using a light emitting diode LED array as a light source for picture formation, a mode changeover switch SW2 is turned to the GND position to bring a level of a clear terminal 3 to a drive circuit 5 to L. When the level of a chip selection terminal 4 is H, an output Ai(i=1-n) of a scanning circuit 7 goes to H sequentially at each 1CK of a clock CK inputted to a terminal 6. When a picture signal is inputted from a terminal 8, a forward current flows to an LED12-i via an FF9-i and an SW10-i to light the LED sequentially. In reading the image of an original, the SW2 is switched to the power supply side and the terminal 3 goes to H, then no LED is emitted and a charge is given. When the level of the terminal 4 goes to H and the CK is given to the terminal 6, an SW13-i is turned on sequentially with the output Ai of the circuit 7, and when light is irradiated on the LED, the discharge current due to the charge is amplified 15 in response to the amount of light and is outputted as a picture signal.

Title: Multi-output switching regulator
Inventor: FUKUCHI TAKESHI
IPC: H02M3/28
Filed: 1989-02-22
Abstract: PURPOSE:To improve the falling characteristic by lowering the terminal voltage of a smoothing capacitor at the input side and maintaining a reference voltage in a second output circuit until the voltage drop of a first output circuit reaches to the reference voltage of the second output circuit when a power source is turned OFF, while furthermore providing a diode for blocking counter flow and a smoothing capacitor. CONSTITUTION:Since a smoothing capacitor 7 at the input side has relatively small capacity, no surge current flows upon turn ON of power source and the power factor is improved. A portion of the output voltage E1 from a first output circuit is fed to a stabilizing power source circuit 20 in order to stabilize the output voltage E2 from a second output circuit to a second reference voltage 5V. The output voltage E2 is stabilized if the output voltage E1 is higher than 5V, and since a diode D8 blocks counter flow even if E1 drops temporarily below 5V, the capacitor C8 serves as a power source thus stabilizing the output voltage until the terminal voltage drops to 5V.

Title: Memory circuit
Inventor: SATO MASA
IPC: G11C11/34
Filed: 1987-02-24
Abstract: PURPOSE:To reduce the power consumption and to improve the reliability of a memory circuit by increasing the discharge current of a word line set at the negative side together with the potential reduced for a word line set at the positive side in response to a temporary rise caused to the collector potential of a discharge detecting transistor for a period during which said transistor conducts from a time point right after a non-selection state is set. CONSTITUTION:The discharge current is concentrically supplied for a period during which the discharge of a word line 23a caused by the conduction of a transistor TRQ14 is detected after a selection state is changed to a non- selection state. Then just a slight amount of the discharge current flows in a non-selection state in a steady mode as well as in a selection state. Thus the current driving power can be reduced for a TRQ12 of a driver and the power consumption is reduced. Then the line 23a is never broken by a electromigration since a large current flows to the line 23a transiently only. Thus the reliability of a memory circuit is improved.
