Title: Production of n-formyl-alpha-l-aspartyl-l-phenylalanine
Inventor: KATO TOSHIHISA
IPC: C07K1/14
Filed: 1991-05-23
Abstract: PURPOSE:To industrially and readily obtain alpha-L-aspartyl-L-phenylalanine methyl ester hydrochloride (alpha-APM.HCl) without carrying out solid-liquid separation of an intermediate from a reaction solution of N-formyl-L-aspartic anhydride with phenylalanine methyl ester (PM) in the course of the reaction. CONSTITUTION:Water is added to a reaction solution of N-formyl-alpha-L-aspartyl-L- aspartyl-L-phenylalanine methyl ester synthesized in an organic solvent to perform extraction and separation of layers at 40-80 deg.C. The formyl group of the N-formyl-alpha-L-aspartyl-L-phenylalanine methyl ester dissolved in the separated aqueous layer is subsequently eliminated to deposit the formed alpha-L-aspartyl-L- phenylalanine methyl ester as sparingly soluble hydrochloride, which is then isolated.

Title: Semiconductor memory device and manufacture thereof
Inventor: AOKI MASAMI
IPC: H01L21/822
Filed: 1994-09-16
Abstract: PURPOSE: To inhibit a leakage current by a parasitic transistor without having an effect on the characteristics of a transfer gate by partially forming an impurity layer having an opposite conductivity type to a plate diffusion layer to the upper section of the plate diffusion layer. CONSTITUTION: A p<+> type inversion preventive layer 7 is formed onto the outer circumferential section of a trench 3 placed at the upper end of an n<+> type diffusion layer 8. Consequently, the inversion preventive layer 7 functions as a parasitic channel stopper between a source diffusion layer 151 and a plate diffusion layer 8. The n<+> type diffusion layer 7 is not formed just under a MOS transistor, thus reducing the possibility of the deterioration of a substrate bias effect, junction breakdown strength, etc. As a result, a parasitic channel leakage current can be inhibited without lowering transistor characteristics. Accordingly, A dynamic type semiconductor memory device having excellent data-holding characteristics can be realized even at the time of fining.

Title: Heat pump unit for hot water supply
Inventor: SAEGUSA KAZUNUSHI
IPC: F24D17/02
Filed: 1983-11-26
Abstract: PURPOSE:To increase the efficiency of a heat pump by preventing frequent driving and stopping of the pump, by using the heat pump by releasing the setting of the primary water level control, and by driving the heat pump only when the water level goes down to the secondary water level, when a large quantity of hot water is used at a time from a hot water tank. CONSTITUTION:When a large quantity of hot water is used, a signal 14 is manually put into a controller 13, which releases the setting of the primary water level in a water level sensor 4, and closes a solenoid valve 6. In this state, hot water is used from a hot water tank 3 without feeding new city water into the tank any more. When the water level in the tank 3 goes down lower than the secondary water level, a water level sensor 4 outputs a signal to the controller 13, which outputs a controlling signal to the solenoid valve 6 to open it, and drives a pump 8 and a heat pump 1 to restore the water level to the setting of the primary water level. By this operation, hot water is fed into the hot water tank 3 at the same time city water is being fed into the tank. The heat pump 1 is continuously driven until the water level reaches the primary water level. The heat pump is prevented from repeated and frequent driving and stopping operations, so that the efficiency of a heat pump can be increased.

Title: Drive current control method for dc brushless motor with independent winding
Inventor: GALBIATI EZIO
IPC: H02P6/28
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To control currents of respective windings individually by a method wherein the signals of two detection resistors are compared with a same reference signal to generate logic triggers and signals generated by monostable multivibrator in accordance with the logic triggers, and signals generated by phase switching are supplied to synthetic logic gates which output signals for driving respective half bridges. SOLUTION: A current which flows through a winding A is supplied by turning on transistors T1A and T4A. If the voltage drop of a detection resistor RS2 exceeds a control voltage, the output of a comparator COMP2 triggers a monostable multivibrator ONE2 to change its output to a logic value 1 for a required period. Since an Ina signal and the output signal of the monostable multivibrator ONE2 after the OR process change a gate output OR-a (= drive signal INa) to a logic value 1, the MOS transistor T4A is turned off and a MOS transistor T3A is turned on. Then, the MOS transistors T1A and T4A are turned on to start the increase of a current in the phase winding A. If the voltage drop of the detection resistor RS2 exceeds the control voltage, this cycle is repeated.

Abstract: PURPOSE:To perform the vertical deflection of an electron beam with a relatively simple structure by arranging a control means of part of an electron beam control means group on the opposite side to a luminous means for a linear electron source and using the control means as a means to deflect an electron beam. CONSTITUTION:Part of an electron beam control means group is arranged as a vertical scan deflecting electrode 1 on the opposite side to a luminous means 5. When the potential to turn the beam current to on is applied to a vertical scan deflecting electrode 1b and the potential difference is applied between 1a and 1b, for example, the potential distribution around a cathode 2 becomes asymmetrical in the vertical direction centering 1b. An electron bean 6 emitted from the cathode 2 is deflected in the vertical direction immediately after the emission, and interlacing can be performed by this action. The vertical deflection of the electron beam can be thereby performed with a relatively simple structure.
