IPC: H03F3/193
Filed: 1987-04-01
Abstract: PURPOSE:To attain high output without prolonging a chip size laterally by using conventional gallium arsenide field effect transistor GaAs FETs in series. CONSTITUTION:For example, sources of two GaAs FETs 1 and drains of FET 2 are connected and the drain of the FET 1 is used as a drain voltage supply terminal and a PF output terminal and a source of the FET 2 is connected to ground. The gate of each FET is connected to gate bias voltages VG1, VG2 by using resistors R1-R3.

Title: Monolithic ic circuit
Inventor: NATSUI YOSHINOBU
IPC: H01L27/04
Filed: 1980-06-17
Abstract: PURPOSE: To obtain a monolithic IC highly resistant to static breakdown by providing a transistor with the collector connected to the input terminal, the emitter to the power supply and the base open.  
     CONSTITUTION: In an IC chip 10, a transistor QI is connected as specified to by- pass electrostatic energy applied on the input terminal depending on a breakdown characteristic between C and E with the base open. Since the breakdown point at the junction between C and E is lower than that between C and B and moreover, negative in the resistance, the voltage shows a considerably low value after the final breakdown. The action of the transistor continues after the breakdown resulting in a much lower impedance than the C-B junction. This minimizes the heating of the elements themselves to protect them from destruction and provides such a low impedance thereby enabling the formation of a monolithic IC highly resistant to electrostatic breakdown and with a large capacity of absorbing electrostatic energy. Grounding through a resistor from the base permits the absorption of variance in the CEO structure. The diode DI is a parastic element.

Abstract: PURPOSE:To obtain the titled molten salt bath for modification enabling the removal of oxide scale on high Cr steel or the like by pickling in an improved state by adding KMnO4 or NaMnO4 to an NaOH-base molten salt bath contg. NaNO3 or KNO3. CONSTITUTION:Oxide scale which is difficult to remove on high Cr stainless steel, heat resistant steel or the like is modified by immersing the steel in a molten salt bath for pickling consisting of 5-40% NaNO3 and/or KNO3, 0.5-10% KMnO4 and/or NaMnO4, and the balance NaOH with impurities. The modified oxide scale is uniformly removed by the following pickling in a short time without causing surface roughening, and reduction of the thickness of the steel due to the pickling can be minimized.
