Title: Filter circuit
Inventor: YOSHIZAWA SHIGEO
IPC: H03H11/08
Filed: 1989-04-17
Abstract: PURPOSE:To obtain a stable and highly accurate filter characteristic by negatively feeding back a level fluctuation of an output signal of a 2nd gyrator type filter circuit to a circuit current supplied to the said filter circuit, and supplying a circuit current corresponding to the former circuit current to a 1st gyrator type filter circuit. CONSTITUTION:When a frequency characteristic of gyrator type filter circuits 1A, 1B is shifted toward a high frequency, since a level of an output voltage VD of an amplitude detection circuit 3 is higher than a DC reference voltage VR, an operational amplifier OP1 decreases the level of a comparison signal VC. A current source circuit 5 reduces circuit currents I1,I2 and gives the resulting current to the gyrator type filter circuits 1A, 1B respectively because the comparison signal Vc is decreased. The frequency characteristic of the gyrator type filter circuits 1A, 1B is shifted toward a low frequency when the value of the circuit currents I1,I2 is decreased and the frequency characteristic is restored. Thus, an always stable and highly accurate frequency characteristic is obtained for both the gyrator type filter circuits 1A, 1B.

Abstract: PURPOSE: To obtain inexpensive slide materials excellent in sliding characteristics such as wear resistance, etc. at high melting point, high hardness which are composed of inorganic fibrous moldings and light alloys in the given fibrous formation ratio and thickness using high pressure freezing and casting method.  
     CONSTITUTION: For example, a slipper surface 3 on a cam shaft 2 of cast iron, steel, etc. in contact with a rocker arm 1 for an internal combustion engine is allowed to be composed of a compound which fills any formed moldings of inorganic fiber like ceramic fiber of the diameter of 1W10μ and of the bulk density of 0.75W1.5g/cc with Al alloy by freezing and casting at a high pressure.

Filed: 1979-07-31
Abstract: PURPOSE: To make possible good patterning, in dry etching of aluminum-copper films by removing the film of copper or copper compound through chemical treatment on the way of etching.  
     CONSTITUTION: At the time of forming the electrodes and wirings of semiconductor devices by dry etching aluminum and copper sand, the depositing copper that hinders the etching is removed. For example, aluminum-copper films are formed to about 1μm thickness on a substrate 1 by a vapor deposition method and photoresist mask 3 is formed thereon. Next, the film 2 is etched to about 0.1μm thickness by a dry etching method. Copper fairly deposits on the surface of the film 2 to form a film 4. This is taken out and is subjected to conc. nitric acid treatment to remove the copper deposited film 4, after which it is rinsed. When it is again subjected to dry etching, good etching may be performed because there is no copper deposited film 4 that hinders the etching.
