Abstract: PURPOSE:To obtain a compound useful as an antiulcer agent and antiplasmin agent, by reducing trans-4-cyanocyclohexane-1-carboxylic acid-phenyl esters in acetic acid in the presence of Raney nickel catalyst. CONSTITUTION:A compound expressed by formula I (R is H or benzyl) is subjected to catalytic reduction in acetic acid using Raney nickel as a catalyst at ordinary pressure-100kg hydrogen pressure and 0-200 deg.C for 1-10hr to provide the aimed product expressed by formula II. The catalyst is used at an amount of 1-100wt.% based on the compound expressed by formula I and the above-mentioned reaction concentration is 0.1-100wt.%. The compound expressed by formula I is obtained by reacting trans-4-cyanocyclohexane-1- carboxylic acid chloride expressed by formula III with a compound expressed by formula IV. Thus the aimed product can be economically obtained without causing hydrolysis of phenyl ester bond and accompanying formation of by- product.

IPC: H01L21/822
Filed: 1982-11-08
Abstract: PURPOSE:To obtain the capacitor having high capacity density and small leak current by a method wherein an excessive-silicon silicon nitride film is formed on a silicon semiconductor substrate, and after a tantalum oxide film has been formed thereon, the surface of the excessive-silicon nitride film is converted into a silicon oxynitride film. CONSTITUTION:An excessive-silicon silicon nitride film 2 is formed in deposition on the surface of a silicon semiconductor substrate 1, and a tantalum oxide film 3 is coated thereon. The substrate 1 consisting of the double-layer film is heat- treated in the atmosphere of mixed gas of oxygen and nitrogen at 1,000 deg.C for three hours, and the surface part of the film 2 is converted into a tantalum oxide film 6 and the film 3 to a tantalum oxide film 7 containing nitrogen. At this time, the formation of tantalum silicide due to the working of the mutual action of film 2 with the film 3 and the substrate 1 is to be prevented. The film 4 has a relative permittivity larger than that of the silicon nitride film and reduces the leak current of the film 3. Subsequently, alumnum is coated on the films 2, 4 and 6, an electrode 7 is formed by performing a patterning, and the titled capacitor is obtained by performing a heat treatment in an N2 atmosphere at 400 deg.C.

Title: Automatic equalizer control system
Inventor: SHINADA SHIGEO
IPC: H04L25/03
Filed: 1981-12-07
Abstract: PURPOSE:To prevent a tap gain from being overregulated even if an impulsive noise is generated, by fixing the tap gain to the value at a detection point of time for a specific time when the amplitude level of an input signal exceeds a specified value. CONSTITUTION:An amplitude comparator 2 and a timer 3 are added newly to an automatic equalizer body 1. The amplitude comparator 2 detects whether the amplitude level of an input signal SIN is higher than a maximum amplitude level when there is no impulsive noise and, when detecting that, starts the timer 3. The timer 3 fixes the value of the tap gain in the automatic equalizer 1 to the value at a starting point for a specific time from the starting point. Therefore, the tap gain is never overregulated owing to an impulsive noise.
