Patent JP-H0529320-A (JP)
Title: Semiconductor device
Inventor: YAGAKE TATSUO
IPC: H01L21/3205
Filed: 1991-07-24
Abstract: PURPOSE:To obtain a semiconductor device wherein an efficient current density can be obtained by a method wherein a metal-film wiring in a part requiring a large electric current out of metal-film wining is formed as a multilayer structure. CONSTITUTION:First, holes are made in an insulating film 9; windows 91 to 96 for individual electrodes of a transistor Q1 and a transistor Q2 are formed; and after that, a metal to be used as a metal-film interconnection is applied, by a vapor deposition method, on the whole surface of a semiconductor substrate 1. An excess metal film is etched and removed. Thereby, first metal-film interconnections 10 to 14 are formed. Then, a second insulating film is formed on the whole surface; after that, windows for contact-electrode extraction use are formed. At this time, holes are made in a second insulating film 15, and the film 15 is etched and removed simultaneously in such a way that the first metal-film interconnection 12 as an interconnection part requiring a large electric current is exposed. In addition, a metal film is applied again to the whole surface; the metal film in parts other than a required part is etched and removed. Thereby, a second metal-film interconnection 17 is formed. Since the metal-film interconnection only in the part requiring the large electric current is formed as a multilayer structure in this manner, there is no danger of a disconnection.

Title: Amplitude modulation circuit
Inventor: SATO HIDEO
IPC: H03C1/00
Filed: 1985-08-21
Abstract: PURPOSE:To reduce the distortion against the fluctuation of a power voltage by inserting a multiplication amplifier to an amplifier section of an input signal to control the amplitude of an amplification pulse to a constant value. CONSTITUTION:The DC fluctuation at a DC power supply input terminal 8 is compensated by a sound amplifier 3 through a sound amplifier 6 by the DC feedback from a low-pass filter 10 to keep the DC output of a pulse width amplifier 9. Further, the DC feedback is given to a multiplication amplifier 13 to vary the sound amplification factor thereby compensating the amplification factor for the change. Thus, the modulation sensitivity is kept continuously constant to attain the amplitude modulation with less distortion.

Title: Charging method of secondary battery
Inventor: TAMAI MIKITAKA
IPC: H02J7/04
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To perform full charging of a secondary battery efficiently in a short time, by sensing the ambient temperature of the charged secondary battery, and by reducing its pulse charging voltage to perform pulse charging, when its ambient temperature becomes low. SOLUTION: A constant-current and constant voltage power supply 3 limits its maximum current and its maximum voltage to respective constant values for charging a secondary battery 2. At this time, the constant current and constant voltage power supply 3 stabilizes the output current thereof to make its value constant, when the ambient temperature of the secondary battery 2 is higher than a preset temperature, and controls the output current thereof to make its value small when the ambient temperature of the secondary battery 2 is lower than the preset temperature. That is, the pulse charging voltage of the secondary battery 2 is set to a fixed voltage, when the ambient temperature of the secondary battery 2 is higher than the preset temperature, and is reduced gradually, according to the lowering of the ambient temperature of the secondary battery 2 from the preset temperature.

IPC: G11B21/10
Filed: 1982-10-21
Abstract: PURPOSE:To attain stable tracking control by interrupting a high frequency error signal while a defect is detected at the reproduced part of a disc and storing a low frequency error signal so as to make the stored value accurate. CONSTITUTION:When the disc 1 has a defect, a defect detecting means 4 detects the defect of a reproducing signal and outputs a defect detecting signal. On the other hand, an error detecting circuit 20 extracts and outputs a tracking error signal. After an error signal is divided into the high frequency error signal passing a branch comprising an analog switch 21 and a high-pass filter 12 and the low frequency error signal passing a branch comprising a low-pass filter 13 and a holding circuit 22, they are added again and applied to a driving circuit 9. When the defect detecting signal is outputted, the switch 21 interrupts the high speed error signal and the circuit 22 holds the low frequency error signal, then the signal applied to the circuit 9 is not zero at the reproduction of the defected part, but a value of the low frequency error signal stored by the circuit 22. Further, the noise at the reproduction of the defected part is decreased.
