Title: Preparation of dl-beta-arylamino acid
Inventor: SHIYANDORU HOSUTAFUI
IPC: C07C227/26
Filed: 1985-03-12
Abstract: The invention relates to a process for the preparation of DL-β-aryl-amino acids of the general Formula.whereinR,R, and R<sub>2</sub> stand for hydrogen, halogen, C<sub>1-6</sub> alkyl, C<sub>1-6</sub> alkoxy, nitro or C<sub>1-4</sub> dialkylamino.An aqueous solution of glycine and an excess of urea is heated and the reaction mixture is subjected to acidic cyclisation. The hydantoin thus obtained is reached with an aromatic aldehyde of the general Formulain aqueous solution in the presence of an excess of ethanolamine or morpholine. The 5-arylidene hydantoin derivative of the general Formulathus obtained is reduced quantitatively in a dilute alkaline medium with a Raney-nickel or a palladium-carbon catalyst to yield the corresponding 5-aryl-methyl-hydantoin derivative of the general Formula R which is subjected to alkaline hydrolysis. The corresponding DL-β-aryl amino acid of the general Formula V is obtained in high yield and may be isolated at the isoelectric point thereof

Abstract: PURPOSE:To absorb the change of the clock duty and the variance on production by varying the extent of delay of the clock signal and data of an IC on the data reception side and discriminating whether relations between a proper delay time for each extent of delay and a setup time are proper or not. CONSTITUTION:Three kinds of data different in extent of delay, namely, data outputted from a semiconductor integrated circuit (IC) 11 and data delayed by delay circuits 31 and 32 are inputted to a multiplexer 23, and one of these data is selected and is outputted to the data terminal of a flip flop 25. Three kinds of clock signal different in extent of delay, namely, the clock signal and clock signals delayed by delay circuits 33 and 34 are inputted to a multiplexer 24, and one of these clock signals is selected and is outputted to the clock terminal of the flip flop 25. It is discriminated by a microcomputer 33 whether timing relations between the clock signal and data are proper or not. Thus, the delay time and the set-up time are arbitrarily set.

Title: Method for executing error correction in reed solomon coding and decoding operation
Inventor: ITOI TETSUSHI
IPC: H03M13/00
Filed: 1986-03-07
Abstract: PURPOSE:To improve the correcting accuracy with no wrong correction by fixing the correction method with a cross-interleaved CIRC having three correc tion capacities. CONSTITUTION:The data are stored in a data memory and then supplied to an arithmetic circuit and a deciding circuit for each syndrome operation and each coefficient operation of an error position polynomial as well as each deci sion of an error position. Then those data are stored in a memory. In an error correction mode the coincidence is studied between the error number LNO obtained by a chain method and the length un of a shift register. Both the correction and a flag are decided tentatively by a Cl decoder and the data deinterleaved by a deinterleaving circuit is supplied to a C2 decoder. The num ber of flags added by the Cl decoder is studied and the correction is inhibited to avoid a miscorrection in case the number of flags is too large.

Title: Car position display device
Inventor: MATSUDA TOSHIO
IPC: B60R21/00
Filed: 1987-03-03
Abstract: PURPOSE:To directly confirm the vehicle width or advance position at night, keeping the driving state, by displaying the indexes which instruct the width of a car, advance direction of travelling wheels, etc., by the transmission medium such as light beams, electric waves, and sound waves on a road surface or the periphery of the road surface. CONSTITUTION:The light beams irradiated from the car position display devices 7 arranged at four corners of a vehicle 6 focus a filament image on the side surface of the car or on the extension line in the longitudinal direction of a traveling vehicle. Therefore, the position such as car width and width between the traveling wheels can be directly confirmed on the road surface within the field of vision without forwardly leaning driver's body outside the car from a driver's seat. Therefore, the car width limit or the traveling wheel width can be always displayed at a constant position by allowing the indexes to be image-focused on the road surface on the extension line in the longitudinal direction of the car even if the driver's attitude or the visual angle is varied. Therefore, the car width and advance position can be directly confirmed at night, and the trouble generated by obstacles, etc., can be prevented.

Title: Manufacture of resin-sealed type semiconductor device
Inventor: NODA TOSHIO
IPC: H01L21/56
Filed: 1990-02-28
Abstract: PURPOSE:To make it possible to surely remove molded item irrespective of the characteristics of sealing resin by a method wherein resin sealing is performed under the condition that a reinforcing plate is arranged over the resin runners of a mold so as to harden the sealing resin integral with the reinforcing plate. CONSTITUTION:In resin sealing, a rectangular reinforcing plate 7 is placed onto a bottom force 1 so as to cover the runner part 3 of a mold and nearly half the base end side of the sub-runner parts 4 of the mold. After that, similarly as before, a top force and the bottom force 1 are brought into close contact with each other so as to fill resin in a cavity. As a result, the resin hardens integral with the reinforcing plate 7. The substantial strength of the resin runner part 3a after the hardening of the resin is determined by the strength of the reinforcing plate 7, irrespective of the characteristic of sealing resin. Accordingly, at the removal from the forces, the resin runner part 3a is scarcely deformed and molded item can be surely removed from the forces. Further, the reinforcing plate 7 can be made of metal material such as iron-based one, stainless steel- based one, copper-based one or the like, organic material such as polyamide resin, aramid resin, carbon fiber or the like, or the like.

Abstract: PROBLEM TO BE SOLVED: To provide a carbon powder material increased in specific surface area by adding a carbon-contained compound to an aromatic condensed polymer followed by thermal treatment. SOLUTION: An aromatic condensed polymer starts thermally decomposing at about 400 deg.C to cause a dimensional contraction, but carbon powder or carbon black causes no dimensional change in the thermal treatment of the condensed aromatic polymer since it is thermally treated. The carbon powder is formed of, for example, a one obtained by thermally treating phenol resin, polyimide, polyamide, or furfuryl alcohol resin at 700 deg.C or higher and 3000 deg.C or lower, or carbon black, 80% or more of which is preferably distributed in 0.1μm or more and 30μm or less. Such a carbon-contained compound is added to the aromatic condensed polymer followed by thermal treatment, whereby a carbon powder material increased in specific surface area can be provided.
