Title: Production of amino acid methyl ester mineral acid salt
Inventor: AJIOKA MASANOBU
IPC: C07C227/18
Filed: 1988-05-18
Abstract: PURPOSE:To obtain a mineral acid salt of an amino acid methyl ester in high yield by esterifying an amino acid with methanol in the presence of a mineral acid, removing methanol by concentration and subjecting the reaction system to azeotropic dehydration in the presence of an organic solvent. CONSTITUTION:An amino acid is esterified by leaving the acid together with methanol for several days at room temperature or heating at a temperature near the refluxing temperature of methanol in the presence of a mineral acid (e.g. hydrochloric acid). After removing excess methanol, the system is added with an organic solvent (e.g. toluene) capable of forming an azeotropic mixture with water and subjected to azeotropic dehydration at <=80 deg.C to obtain the objective compound. The objective mineral acid salt of amino acid methyl ester is useful as a synthetic intermediate for peptides, a synthetic raw material for aspartame which is a peptide-type sweetener or as a raw material for pharmaceuticals.

Abstract: PURPOSE:To suppress temperature rise due to heat generation of a winding by taking out working liquid in the inside of the winding composed of a thin heat pipe from a terminal part to the outside by a connecting pipe for circulating through a heat medium so as to cool the inside. CONSTITUTION:Working liquid inside in a primary winding 1 composed of a heat pipe is taken out into a connecting pipe 7 for being circulated through a heat exchanger 8. At this time, working liquid is cooled inside a heat exchanger 8 so as to cool the inside of a current transformer. Thereby, temperature rise in the inside due to heat generation of the primary winding is suppressed so as to prevent the generation of cracks and the deterioration due to its heat to a resin mold layer 11. Further, the resin mold layer 11 can be made to fully function as a structural material even if current density of the primary winding is not reduced.

PI control section 5 leads the winding application timing by lambda deg.so that the delay angle psi is zero. When lead angle control is carried out similarly for other phases, the power factor approaches to 1.

Abstract: PURPOSE:To make a driving device smaller in size and compacter in constitution, by driving a driven body by utilizing the impulsive force of a piezo-electric element and holding the driven body by means of the attracting force of a permanent magnet. CONSTITUTION:When a pulse voltage is applied across a piezo-electric element 6, an impulsive force is produced in the piezo-electric element 6 and a lens frame 4 is repulsed forward through a permanent magnet 8. The repulsed lens frame 4 is attracted and held by another permanent magnet 7. Therefore, the convex lens 3b of the rear group of an objective lens 3 is displaced forward together with the lens frame 4. When a pulse voltage is applied across another piezo-electric element 5 in such state, an impulsive force is produced in the piezo-electric element 5 and the lens frame 4 is repulsed backward through the permanent magnet 7 and attracted and again held by the permanent magnet 7. Therefore, the convex lens 36 of the rear group is displaced backward together with the lens frame 4. Thus the focal point of the objective lens 3 is changed.
