Title: Simple production of high quality captopril
Inventor: KINOSHITA KOICHI
IPC: A61K31/40
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound having a high quality by subjecting a specific substrate compound to a hydrolysis reaction under specific conditions to release the RCO group, and subsequently isolating the product, while inhibiting the by-production of impurities difficult in their purification and removal. SOLUTION: This method for producing the captopril of formula II comprises subjecting a substrate compound of formula I (R is an alkyl, an alkoxy) to a hydrolysis reaction in the presence of a strong acid (preferably hydrochloric acid) in an aqueous medium under conditions comprising a pH of <=1 and a temperature of >=40 deg.C (preferably 50-100 deg.C) and subsequently isolating the RCO group-released product. The strong acid is preferably used in an amount of >=0.1 time molar equivalent, preferably approximately 0.2-2 times equivalent that of the compound of formula I. The substrate compound of formula I includes N-(D-α-methyl-β-acethylthiopropionyl)-L-proline. The captopril useful as an antihypertensive medicine can thereby be obtained in a high yield and at a low cost.

Then the residual basicity reserve is neutralized by at least one acid containing at least one element selected from boron, phosphorus and sulfur. In the case that such an acid is directly introduced into the reaction medium, a mineral acid is selected from orthoboric acid, metaboric acid, phosphoric acid, their derivatives, carboxylic acid containing sulfur, or the like.

Title: Production of liquid crystal cell
Inventor: TORIGOE TSUNEMITSU
IPC: G02F1/133
Filed: 1987-11-18
Abstract: PURPOSE:To prevent electric discharge between display electrodes occurring in static electricity at the time of rubbing and to improve yield by printing and forming silver paste layers on a substrate as short circuiting means. CONSTITUTION:Many transparent display electrodes 2 are patterned on the glass substrate 1 and oriented films consisting of thin dielectric films are formed on the surfaces of the respective display electrodes 2. Terminal parts 3 led out of the display electrodes 2 are formed at prescribed pitches in array shapes for each of the patterns corresponding to respective liquid crystal cells and all the terminal parts 3 on the substrate 1 are short circuited by the extremely narrow silver paste layers 4. After the silver paste layers 4 are formed by printing, the layers are subjected to a rubbing orientation treatment. Although static electricity is generated on the surface of the glass substrate 1 at the time of the rubbing, the display electrodes 2 are short circuited via the silver paste layers 4 and are, therefore, maintained at the same potential and there is no danger of the electric discharge. The discharge between the display electrodes occurring in the static electricity at the time of the rubbing is thereby prevented and the yield is improved.

Title: Hermetic motor-driven compressor
Inventor: HIRATSUKA SATOSHI
IPC: F04B39/02
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To improve reliability in response to the enlargement of a variable operation speed range accompanied by the use of an invertor in a hermetic motor-driven compressor. SOLUTION: In a joint part between a rotary shaft 7 and an oil filler cone 27, the inner circumferential surface of the cone 27 and the inner circumferential surface of a fuel oil pump 28 are matched with each other, and a step difference is eliminated. Since lubrication is not disturbed by the step difference when lubricant oil sucked up by the cone 27 is brought from the cone 27 to the pump 28, an appropriate amount of lubrication can be secured during low speed operation. A lubricating condition can be improved in each sliding part in the inside of this compressor, and occurrence of wear can be suppressed.

Title: Logon user id control system
Inventor: KOBAYASHI YUKA
IPC: G06F21/31
Filed: 1990-10-25
Abstract: PURPOSE:To control logon user ID and to improve security by inspecting user ID and a password and checking whether the user ID obtained by a terminal generating a logon request can be used or not at the time of receiving the logon request. CONSTITUTION:When an on-line terminal equipment inputs user ID and a pass word, a logon request receiving part 6 checks the validity of the user ID and the combination of the user ID and the password, when the user ID is invalid, informs the rejection of the logon request to the terminal equipment. In the case of valid ID, the user ID is informed to a logon user ID inspection part 5 and transfers control to the part 5. The inspection part 5 acquires the terminal ID name of the terminal generating the logon request and refers to a logon user ID inspection table 4 based upon the terminal ID name. Consequently, the decision of logon validity can be improved.

A silicon oxide film 8 is formed on the resistance 7, and aluminum wirings 9 are formed thereon. Transition metal such as molybdenum, tungsten, or titanium is introduced into the films 5, 8 as interlayer insulating films. With such a configuration, the films 5, 8 contacted with the resistance 7 are increased in electron collecting sectional areas by metallic atoms to become readily charged to negative. Thus, the VG dependency of ID of an MOS transistor which forms the resistance 7 is shifted in parallel in a positive direction. Accordingly, the characteristic that the ID is stable can be obtained in an available voltage range as designated by a solid line, and the ISB can be further stabilized.
