Abstract: PURPOSE:To permit the stabilized production of high-quality products for a long period of time by a method wherein a component having an inner layer, whose structural material of carbon is converted into silicon carbide consisting of the principal constituent of beta-type silicon carbide, and an outer layer, coated with the deposite of silicon carbide more fine than the inner layer, is employed for the part of a hearth. CONSTITUTION:Gas, containing silicon such as SiO or the like, and the structural material of carbon are converted and reacted at the temperature of 1300-1950 deg.C to obtain a silicon carbide layer, whose principal constituent is beta-type silicon carbide. According to this method, resistance to heat shock is improved, cracks in a surface layer are never generated and the stability of the layer is increased. However, fine cavities exist and absorbs by-product gas generated from works to be treated when it is used as the component of a high-temperature heating furnace and bad affection is applied on the other products whereby the part is coated by the deposite of fine silicon carbide. In another method or CVD method, the coating of silicon carbide is formed through the heat cracking of halogenated silicon such as silicon tetrachloride or the like and an organic substance such as toluene or the like in the atmosphere of hydrogen at the temperature of 1000-1800 deg.C.

Title: Separation of cystine or cysteine and tyrosine
Inventor: ONOUE HIROTAKE
IPC: C07C313/00
Filed: 1982-04-28
Abstract: PURPOSE:To separate the titled substances from a mixture containing cystine and tyrosine, by dissolving the mixture in a mineral acid, converting the cystine in the solution to cysteine by reduction, neutralizing the solution with an alkali, separating the precipitated tyrosine by filtration, and concentrating the filtrate. CONSTITUTION:A mixture of L-cystine and L-tyrosine is dissolved in hydrochloric acid and the solution is used as the catholyte. The anolyte is 5% sulfuric acid solution, and a cation exchange membrane is used as the membrane. The catholyte is reduced by dipping platinum electrodes in the catholyte and the anolyte, and passing DC current through the membrane. After ascertaining the complete reduction of L-cystine to L-cysteine by thin-layer chromatography, the catholyte is adjusted to pH 5 by dripping ammonia water, and the precipitated crystal (L-tyrosine) is recovered by filtration. The filtrate is oxidized by adding hydrogen peroxide solution dropwise to the filtrate until the filtrate does not develop blue color by nitroprusside reagent. The oxidized filtrate is mixed with hydrochloric acid to dissolve the precipitated crystal, added ammonia water dropwise to attain 2.5pH, and the reprecipitated crystal (L-cystine) is recovered by filtration.

Title: Exothermic printing element
Inventor: YASUMI KUNIO
IPC: B41J2/335
Filed: 1978-06-12
Abstract: PURPOSE:To make the rise of heat evolution to thermographic paper faster, make the holding time of recordable temperature longer and make the time necessary for recording shorter as a whole by so constituting the exothermic printing element that currents concentrate at the surface part of resistors. CONSTITUTION:After a RuO2 base resistance layer 8 is bonded through vapor deposition, coating, etc. on an alumina substrate 1 being an insulation type substrate, gold electrodes 21, 22 and further a glass film 7 being a protecting layer are provided on the substrate 1 and layer 8. The mutually opposing end parts of the electrodes 21, 22 are formed to such a shape wherein the opposing distance is longer at the portions closer to the substrate and becomes shorter as they go further from the substrate, i.e., as they go closer to the peak part in contact with the thermographic paper, like the dotted line. Hence, the resistance between the electrodes 21, 22 is higher at the portions closer to the substrate 1 side and lower at the portions closer to the thermographic paper side. As a result, when voltage is applied between the electrodes 21, 22, currents concentrates at the peak part of the layer 8 and the evolution of heat at that portion is high and temperature rise fast.

Filed: 1989-03-24
Abstract: PURPOSE: To reduce the data amount required for transmitting a advice for bypassing by storing a place name and a bypass interval name in a storage field where they can be commonly address-designated. CONSTITUTION: A storage device 12 is provided with a storage field 16 which is selection possible via an address input side 26, and the filed 16 is provided with a storage place 20.

Title: Program-searching mechanism of video tape recorder for cassette tapes
Inventor: OGIJI KENJI
IPC: G11B15/087
Filed: 1978-06-14
Abstract: PURPOSE: To achieve simpler construction and operation by mounting a cue-signal- reproducing head in such a manner as to make contact to the back side of the magnetic tape in a cassette half.  
     CONSTITUTION: A full-width erase head 8 positioned upstream of each recording head records the program-search cue signal for a fixed time at a width wider than the width of a magnetic tape 4 at the recording operation. An audio control head 14 also operates similarly. A cue signal head 19 of a width much narrower than the recording width of the abovementioned cue signal is mounted in a cassette half 1 in the position where it makes contact to the back side of the tape 4 when the tape is not pulled outside. Hence, if a fast-feed or rewinding operation is carried out where the tape 4 is not pulled from the half 1, the head 19 accurately reproduces the cue signal even if the tape 4 travels at a high speed between the feed and take-up reels 2, 3, thereby causing the tape 4 to stop and detecting the program-search position.
