IPC: C07C313/00
Filed: 1981-06-01
Abstract: PURPOSE: To obtain the titled compound useful as food additives, etc. in high yield while reutilizing by-products industrially and advantageously, by decomposing a reaction product between a β-halogenoalanine and a trithiocarbonate with an acid under mild conditions easily with a high volume efficiency.  
     CONSTITUTION: A β-halogenoalanine, e.g. β-chloroalanine or β-bromoalanine, is reacted with a trithiocarbonate, e.g. lithium trithiocarbonate or sodium trithiocarbonate, and the resultant mono(aminocarboxyethyl)ester salt of the trithiocarbonic acid is decomposed with an acid, e.g. HCl or H 2 SO 4 , to give the aimed DL-cysteine. The molar ratio of the raw material compounds are 1:(1W10), preferably 1:(1W5). The reaction time is about 1W3hr at 0W80°C. Carbon disulfide formed as a by-product is recovered by the distillation, and reusable for preparing the trithiocarbonate.

Title: Composite plate and its manufacture
Inventor: MORI AKIRA
IPC: H01L23/373
Filed: 1990-03-30
Abstract: PURPOSE:To attain a sufficient heat dissipation effect by forming heat transfer phases in a matrix so as to penetrate in the direction of plate thickness and disperse in the plate face. CONSTITUTION:A structure is such that heat transfer phases 3 based on copper or silver are dispersed in a matrix 2 based on molybdenum or tungsten. That is, the matrix 2 is continuous in a network form in the cross section parallel with the plate face, while the heat transfer phases 3 are severed like an island of circular cross section in the matrix 2 and each penetrates the front and back of a plate. Such a heat dissipation plate 1 has a so-called anisotropicity that qualities are different with direction along the plate thickness and the plate face. That is, each heat transfer phase 3 is continuous in the plate thickness and therefore contributes to heat transfer between both faces of the plate. But since the phases are sheared in the direction along the plate face, they are not accumulated in the plate face as the whole despite local expansion with the result that thermal expansion depends upon characteristics of the matrix 2.
