IPC: C07C43/20
Filed: 1993-02-16
Abstract: PURPOSE:To easily obtain the subject compound in high yield and high purity, useful as a sensitizer for heat-sensitive recording paper by reaction between an alkali metal salt of beta-naphthol and benzyl chloride in a specific polar organic solvent at specified temperature. CONSTITUTION:The objective compound can be obtained by adding respectively equivalent or somewhat excess amounts of beta-naphthol and a hydroxide, carbonate or bicarbonate of an alkali metal to a polar organic solvent selected from N,N-dimethylformamide, N,N-dimetnylacetamide and N-methyl-2-pyrrolidone followed by adding benzyl chloride to the system and then conducting a reaction at 20-130 deg.C. Preferably, the polar solvent is distilled off from the system at reduced pressures after completing the reaction to deposit a crystal component followed by addition of an organic solvent (pref. chloroform or hexane) and water to dissolve the crystal component and then the organic layer is separated, which is then concentrated and cooled, and the deposited objective crystalline compound is then separated.

Title: Schottky diode
Inventor: ICHIKAWA KATSUNORI
IPC: H01L29/872
Filed: 1989-03-01
Abstract: PURPOSE:To realize a rectification circuit having high rectification efficiency by dividing a Schottky barrier so as to form a Schottky diode out of a plurality of unit cells, and selecting the area of the Schottky barrier part and the thickness of a low concentration semiconductor layer so that the area of a high concentration semiconductor substrate may be larger than the total area of the unit cells. CONSTITUTION:A Schottky barrier 3 is divided by insulating substance, for example, SiO2 films 7 so as to put it in such structure that the Schottky diode is composed of a plurality of unit cells 8 which are formed by being divided at A and B lines. And it is so constituted that the currents from the Schottky junction of each cell 8 expands gradually within a low concentration semiconductor layer 2 and flow into a high concentration semiconductor substrate 1. And the area of a Schottky barrier part 3a and the thickness of a low concentration semiconductor layer are selected so that the unit cell may have a spread angle of about 45 deg.C in depth direction, which enables respective current lines to avoid overlapping each other between several adjacent unit cells and the currents to flow into the high concentration semiconductor substrate 1. Accordingly, the area of the Schottky barrier is made small, so the reverse currents becomes small by the area ratio of the Schottky barrier. Hereby, rectification efficiency can be improved.

Title: Resin disk
Inventor: SUENAGA JUNICHI
IPC: B29D7/00
Filed: 1985-03-11
Abstract: PURPOSE:To obtain a resin disk, the dimensional change due to temperature of which is small and consequently is applicable to precision machinery field such as high density magnetic disk, optical disk and the like by a structure wherein the titled resin disk consists of polymer enabling to form anisotropic melt and the linear expansion coefficient of the diameter of which is 10<-5>( deg.C<-1>) or less. CONSTITUTION:The titled resin disc consists of polymer enabling to form anisotropic melt with the linear expansion coefficient of the diameter of 10<-5>( deg.C<-1>) or less. The resin disc is obtained by injection-molding polymer, which enables to form anisotropic melt, by using a circular molding tool with a gate at the center. The reason why the linear expansion coefficient of the diameter of the disc is small is that the orientated liquid crystal polymer resin has not only small linear expansion coefficient in the direction of orientation but also small cubical expansion coefficient. Concretely, the linear expansion coefficient in the direction of orientation is as small as of the order of 10<-6>( deg.C<-1>) and there is a possibility that the cubical expansion coefficient is of negative value. The resin disk with extremely small linear expansion in diameter is considered to be obtained by the result of the sum of said small expansion coefficients.

Title: Method and device for seeding on direct seeding and cultivation in water-logged soil
Inventor: KANASUGI HARUKI
IPC: A01C7/00
Filed: 1989-03-01
Abstract: PURPOSE:To prevent the excess tillering and lodging of seedlings by opening a furrow in soil and press-seeding on the bottom of the furrow. CONSTITUTION:A furrow having the longitudinal cross section of a V-shape or reverse trapezoid having a depth of 1-5cm and an opening angle of 30-90 degree is opened with a furrow-making float 2, and calcium peroxide powder- coated seeds are sowed on the bottom of the furrow from a seedling pipe 4.

Title: Receiver
Inventor: KUROBE AKIO
IPC: H03M5/04
Filed: 1987-03-04
Abstract: PURPOSE:To prevent malfunction of a receiver due to impulse noise by providing additionally the titled receiver with an integration circuit integrating a unipolar RZ signal, a 2nd comparator comparing the output of the integration circuit with a reference voltage, and an OR element outputting the OR of the output signal of the 2nd comparator and the unipolar RZ signal to a reset terminal of a monostable multivibrator. CONSTITUTION:An OR signal of comparators 9, 10 and the output of a comparator 15 are ORed by an OR element 16, and outputted (G) to a reset terminal of a monostable multivibrator 12. With the reset terminal at a low L level, the time limit operation of the monostable multivibrator 12 is intermitted and the output goes to a high H level. Moreover, when the pulse width of the line is shorter than a delay time  T, the output of the OR element 15 goes to a low L level at a point of time when the pulse of the line side is lost, to reset the monostable multivibrator. Thus, the impulse noise or the like is induced at the line and the operation of the monostable multivibrator is stopped at a point of time of the pulse is lost. Then, the output is restored to the high H level momentarily, and the output of an errorneous NRZ signal is prevented.

Title: Dry etching method
Inventor: KANAMORI JIYUN
IPC: H01L21/3065
Filed: 1981-04-03
Abstract: PURPOSE:To freely adjust the speed ratio of a thermal oxide film and a PSG  film by a method wherein gas flow amount or etching pressure is controlled for etching. CONSTITUTION:A semiconductor substrate (having a thermal oxide film and a PSG film) is arranged on a parallel flat-plate electrode 3 located at the lower side of a parallel flat-plate type etching device consisting of an enclosed container 1, parallel flat-plate electrodes 2, 3, high-frequency power source 4, and exhaust port 5. Furthermore, for example, CF4 and H2 are used as gases. In this case, with H2 gas flow amount decreased, etching speed ratio will become small. Conversely, an increase in H2 gas flow amount permits the etching of the PSG film to expedite at high speed. Anisotropy can be maintained as the parallel flat-plate type etching device is used. When C2F6 gas and CHF3 gas are used, the similar result can be obtained by varying etching pressure by maintaining gas at a constant flow amount.
