Title: Method for resolving clycidyl-3-nitrobenzenesulfonate into its optically active enantiomers
Inventor: JIYON KUROSUBII
IPC: C07D301/32
Filed: 1991-01-24
Abstract: PURPOSE: To optically resolve the subject compd. by bringing a supersaturated soln. of a mixture of enantiomers of glycidyl 3-nitrobenzene sulfonate into contact with a seed crystal of one enantiomer to grow a crystal and then separating the crystal.  
     CONSTITUTION: Glycidyl 3-nitrobenzenesulfonate is mixed with a polar org. solvent (e.g. a 1 to 6C alkanol) to prepare a supersaturated soln. of the mixture of enantiomers. The soln. is brought into contact with a seed crystal (seed enantiomer) of one enantiomer to form a crystal containing the excess seed enantiomer. Then the crystal containing the excess seed enantiomer is separated from the soln. for resolution. The optically active glycidyl 3- nitrobenzenesulfonate is useful as an intermediate for synthesis of an optically pure β-blocker heart drug.

Title: Token passing type data transfer system
Inventor: TAKATANI MATSUHIKO
IPC: H04L12/42
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a network by reading in each station a reset identification code and performing reset processing of a station circuit in use after transmitting a token frame so as not to destroy it. SOLUTION: A transmission control part 12 generates a transmission frame, based on the data of a transmission buffer 13b of a memory part 13, upon acquiring a token. When a frame has been received through the network LN, demodulates it, transfers data to a reception buffer and checks whether or not the frame is a normal frame. An arithmetic processing part 11 performs a processing corresponding to a program stored in a program memory part 14 and performs management of transmission/reception data or the like. Then, in an abnormality in token transmission, a reset identification code is added to the token frame and the station which acquires the token frame performs reset processing of the station circuit in use corresponding to the reset identification code after transmission to other station is completed.

Filed: 1990-01-18
Abstract: PURPOSE:To increase a critical output and to improve an allowance for a thermal limit value of a fuel by a construction wherein bumps of which the upper and lower end parts are made to communicate with the outside of a channel box are provided in the upper part of the channel box surrounding a fuel bundle. CONSTITUTION:On the downstream side of an effective heating part of a channel box (CB) 1, bumps 21 each forming a part of a cylinder are provided except for a corner angle part 1a which constitutes the center of a lattice when four fuel assemblies of one set are arranged in the shape of the lattice. A flow 15 of a liquid film in the CB 1 runs upward through the CB 1, forming a part of a two-phase flow. This flow 15 separates from the wall surface of the CB 1 on the lower side of the bumps 21. Since the inside and the outside of the CB 1 are made to communicate with each other by openings 22 made on the downstream side of the bumps 21, a pressure difference acts on a coolant inside 11 of the CB 1 indicated by an arrow 13 and a coolant outside indicated by an arrow 14, a strong turbulence 16 occurs in the vicinity of a place above the openings 22 and thereby the separating liquid film is helped to be a liquid drop.

Filed: 1982-01-21
Abstract: PURPOSE:To eliminate apparent ill effect exerted on a picture due to switching action of an antenna switch, by switching the antenna switch synchronously with a video synchronizing signal supplied from a tuner circuit. CONSTITUTION:A signal A turned on by a control circuit 10 is fed to a D type FF circuit 14 when an external control switch 13 is operated and then stored in the circuit 14 with a vertical synchronizing signal SP. Then a signal B led out of the circuit 14 is turned on and off and applied to a delaying circuit 15 to be delayed. This delayed ON output signal C is applied to an antenna switch 6. The delay time of the circuit 15 is set so that the switching time point of the switch 6 is identical with a time point which is approximate to the next signal SP. Therefore, even if noise arises at the switching time point, the noise is limited at a masked area of the CRT of a picture receiver, so that no visual problem is produced. The case when the signal A fed from the circuit is changed to OFF from ON is referred to the same.

Abstract: PURPOSE:To prevent a gate oxide film from becoming thin near a field and then to increase a dielectric strength by heat-treating a silicon substrate in an oxidizing atmosphere after heat-treating it in an atmosphere including hydrochloric acid gas, with the silicon substrate being brought into contact with silicon material. CONSTITUTION:A field oxide film 2 for element isolation is selectively formed on a silicon substrate 1. After that, the silicon substrate 1 is put on a susceptor whose surface is coated with a silicon film, with the surface of the silicon substrate 1 being brought into contact with the surface of the susceptor and then it is heat-treated in an atmosphere including hydrochloric acid. At that time, a silicon layer 3 is formed on the surface of the silicon substrate 1 due to chemical reaction between the silicon film of the susceptor, which will become a silicon source, and hydrochloric acid. Then, by oxidizing the silicon substrate 1 in an oxidizing atmosphere, the silicon layer 3 is changed to silicon oxide and then a gate oxide film 4 is formed. By this method, a dielectric strength of the gate oxide film 4 is increased.
