Abstract: PURPOSE: To obtain a lactam useful as a remedy for peptic ulcer, etc. and an intermediate for other medicines in high yield industrially and efficiently, by reacting a 1-benzoyl-pyrrolidin-5-one-2-carboxylic acid halide with a secondary amine.  
     CONSTITUTION: N-Benzoylglutamic acid is reacted with a phosphorus halide under mild reaction conditions to give a 1-benzoyl-pyrrolidin-5-one-2-carboxylic acid halide of formula I (X is halogen) in high yield. The resultant compound of formula I is then preferably without isolation from the reaction mixture reacted with an amine of formula II (R 1  and R 2  are 1W6C alkyl or together with the adjacent N link to form a heterocyclic ring) under mild condition in the absence of a solvent in a short time of about 1W2hr to give a lactam of formula III almost quantitatively. According to the method, the lactam of formula III can be prepared in high yield by using the conventional reactor with saved energy.

Filed: 1992-03-10
Abstract: PURPOSE:To obtain a satisfactory reduced print by making inputted print data into a multi-level code in accordance with a reduction ratio so as to execute multi-level print-out. CONSTITUTION:The light-emitting timing of a laser diode(LD) 27 is not synchronized with an image element clock and is controlled only by the voltage level of image element data so that multi-level printing within one image element in a main scanning direction is executed.

Title: Semiconductor device
Inventor: SUZUKI HIDETAKE
IPC: H01L29/812
Filed: 1978-04-28
Abstract: PURPOSE: To obtain a high-output device by increasing the dielectric strength by interposing one part of the channel layer between the buried layer and buffer layer (or the substrate), and also to prevent the gain from lowering by keeping the connecting resistance of the source sufficiently low.  
     CONSTITUTION: In contrast to the usual constitution, buried layers 4' and 5' are grown from the halfway part of the channel layer. The sufficient dielectric strength can therefore be obtained between buried layers and buffer layer 2 (substrate 1 when there is not layer 2). However, the effect of anchoring the high electric field of layer 5' lowers and the dielectric strength depending upon it also lowers, but high dielectric strength can be obtained collectively because of the improvement of the dielectric strength with layer 2. Further, the connection resistance of source 4' is very low because of the n +  buried layer and the lowering of the gain is a lettle. Onto GaAs substrate 1, semi-insulating GaAs with additive Cr, etc., and a non-additive high-resistance layer or a layer of the reverse conduction type to the channel layer are provided so as to obtain a buffer layer, so that a hihg-gain and high-output device can be obtained.

IPC: G06F15/00
Filed: 1991-03-18
Abstract: PURPOSE:To shorten time for connecting a line by calculating the sum of the character codes of received characters and analyzing the relevant character pattern when it is coincident with the constant value of a character identification table. CONSTITUTION:The total sum of the codes of the character patterns is registered on a character identification table 1, and the total sum of the codes of the received characters is stored in an arithmetic area 2. Namely, the total sum of the codes of the character patterns is calculated in advance and registered on the character identification table 1, the total sum is calculated by adding the codes of the received characters in the case of reception into the arithmetic area 2 and when the total sum stored in this arithmetic area 2 is registered on the character identification table 1 in the case of receiving the end character or the like, it is judged that the relevant character pattern is received. Therefore, since the sum of the character codes of the received characters is calculated and it is judged in the case of coincidence that the reception is successful, the number of processing steps is decreased, and it is possible to easily deal with the increase of the character patterns.

Title: Gold plating liquid
Inventor: KIKUCHI HIROSHI
IPC: C23C18/44
Filed: 1989-03-06
Abstract: PURPOSE:To allow the extremely stable use of a gold plating liquid which does not contain harmful cyanide by using sulfur oxyacid ions, nitro compd. or azo compd. or org. bromine compd. as a complexing agent for gold ions. CONSTITUTION:The sulfur oxyacid as the complexing agent can complex and dissolve the gold ions in an aq. soln. within a prescribed range. However, the oxyacid ions of sulfur having the complex formability to the gold ions are thermodynamically unstable and, therefore, decomposes of themselves in the plating liquid. The active species generated at this time reduce the gold ions and generate the fine particles of gold in the plating liquid. The nitro compd. or azo compd. or org. bromine compd. is added to the complexing agent in order to eliminate this unstability. The electrochemical active species generated by the natural decomposition of the oxyacid ions of the sulfur are, therefore, rapidly oxidized and are made harmless, by which the reduction of the gold ions is prevented.

Title: Turbo type vacuum pump exhaust system
Inventor: MASE MASAHIRO
IPC: F04D27/00
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To simplify a driving control system by driving the driving motor of a high vacuum pump and the driving motor of a low vacuum, pump by one power supply controller. SOLUTION: A high vacuum pump 28 and a low vacuum pump 27 are communicated with each other through a piping 24, both pumps 28, 27 are connected through one power supply controller 22 and a wiring 23. When a pump is started, pressure in the high vacuum pump 28 is the atmospheric pressure. When atmospheric pressure operation is continued, the high vacuum pump 28 becomes in transient load condition. Since the high vacuum pump 28 and the low vacuum pump 27 are started simultaneously, rotation is raised, and also back pressure of the high vacuum pump 28 is reduced by exhaust action of the low vacuum pump 27 so as to continue normal operation of the high vacuum pump 28. Also it is possible to miniaturize the high vacuum pump 28, and facilitate direct installation of a vacuum chamber.  It is thus possible to facilitate changes of the kinds and the numbers of the high vacuum pump, and also it is possible to carry out simple driving control since one power supply control including one low vacuum pump is arranged.
