Title: Production of beta-mercaptopropionic acid
Inventor: TOMIOKA TETSUZO
IPC: C07C323/52
Filed: 1990-11-19
Abstract: PURPOSE:To easily obtain the subject compound in high yield at a low cost by converting thiodipropionic acid to an alkali metal salt with an alkali metal hydroxide, reacting in a concentrated aqueous solution of an alkali metal sulfide under heating for a prescribed period and acidifying the reaction solution with a basic acid. CONSTITUTION:The objective compound of formula III useful as a raw material for a resin for lens, a crosslinking agent for acrylate polymer, a hardener of epoxy resin, etc., can be produced by using thiodipropionic acid of formula I preferably obtained as a by-product of the reaction of sodium sulfide with acrylonitrile as a starting substance, converting the substance to an alkali metal salt of formula II with an alkali metal hydroxide, adding the salt to a concentrated aqueous solution of an alkali metal sulfide such as Na2S, reacting the components with each other by heating at 110-130 deg.C for a prescribed period (1 to several hours) and acidifying the reaction solution with a basic acid such as sulfuric acid or hydrochloric acid, The use of the alkali metal hydroxide in excess is economically preferable because the consumption of expensive alkali metal sulfate can be decreased in compensation for the increase of the consumption of the inexpensive alkali metal hydroxide.

Abstract: PURPOSE:To inexpensively obtain an inductor having good shape retension and good DC superposing characteristic without influence of assembling accuracy of an inductance by employing a diaferromagnetic material or a sintered oxide similar to the diaferromagnetic material as a sheathed base. CONSTITUTION:A sintered oxide used as the sheathed base of an inductor contains as Zn ferrite series a composition of 30-52% of Fe2O3, 1-12% of CuO and 36-69% of ZnO by molar ratio. Since this is made of diaferromagnetic material or the material similar to the diaferromagnetic material, it can be preferably employed as the sheathed base, and since its electric insulating resistance is extremely larger 10<5> ohms or more than that of normal Zn ferrite, it can be preferably used in high frequency. This inductor is not sensitive in an assembling accuracy, and not affected by a stress. Further, its DC superposing characteristic is good and the inductor having high Q can be designed. Moreover, since it can be sintered at a low sintering temperature, its manufacturing cost is reduced, and a mass production is performed.

Title: Electrostatic breakdown preventive circuit
Inventor: IMAMURA KAZUO
IPC: H01L29/78
Filed: 1988-12-14
Abstract: PURPOSE:To protect an integrated circuit against electrostatic breakdown without giving any influence to an input signal even if a power terminal is grounded by a method where a parallel connection circuit composed of a condenser and a resistor is inserted between a diode and a power terminal. CONSTITUTION:When a power voltage and a signal Vi are applied to a power terminal TE and an input terminal T1 respectively, as the voltage of the signal Vi is lower than that of the power terminal TE, a diode is put in a non- conductive state, and a condenser C and a resistor R have no effect on the signal Vi applied to the input terminal Ti. On the other hand, the condenser C becomes low in impedance to a high frequency voltage such as a surge voltage or the like, so that the input terminal Ti is put in a low impedance state to the surge voltage and no surge voltage appears at the input terminal To. By this setup, an integrated circuit device of this design can be protected against electrostatic breakdown without having any influence on an input signal even if the power terminal TE is grounded.
