Title: Production of 1,2,4-thiadiazole-5-thiol and derivative thereof
Inventor: UEDA SHINJI
IPC: C07D285/08
Filed: 1986-03-11
Abstract: PURPOSE:To carry out reaction at a low temperature and in a short time and industrially and advantageously obtain the titled high purity compound, particularly useful as a raw material for beta-lactam based antibiotic substances in simple operation, by reacting an inexpensive thiolating agent with a specific halogen derivative. CONSTITUTION:A compound expressed by formula I (R is H or lower alkyl) or salt thereof is halogenated to give a halogen derivative expressed by formula II (X is halogen) and excess nitrous acid present in the reaction solution is removed by decomposition with urea, etc., to adjust the pH of the reaction solution to an about neutral value with an alkali without isolating the halogen derivative expressed by formula II. The resultant reaction solution is then reacted with a thiolating agent at 0-50 deg.C for about 1hr. After completing the reaction, insoluble materials in the reaction solution are removed and the reaction solution is acidified with an acid, e.g. sulfuric acid, etc., to afford the aimed high-purity crystal compound expressed by formula III. Sodium hydrosulfide, Na2S, potassium hydrosulfide, etc., are used as the thiolating agent.

Title: Method and apparatus for butting for butt welding of end of steel strip
Inventor: FUJII MAMORU
IPC: B23K26/21
Filed: 1986-03-11
Abstract: PURPOSE:To enable quick butting without a gap even if steel strips are lightly gaged by attracting and holding the rear end of the preceding steel strip by means of a magnetic chuck, raising the front end of the succeeding steel strip, and directing the butt face thereof diagonally downward. CONSTITUTION:The cut preceding steel strip 1 is transferred to a welding position B by a moving device 10. One electromagnetic chuck 6 is energized to fix and magnetize the preceding steel strip in this position. The next succeeding steel strip is cut by a cutter 3 and is fed to the welding position B by pinch rolls 13, 14. A loop roll 12 is raised when the front end of the succeeding steel strip 2 passes by the roll 12. The butt face at the front end of the succeeding steel strip is consequently directed diagonally downward. The succeeding steel strip 2 is next fed to the welding position B, then the butt face at the rear end of the preceding steel strip 1 is not magnetized and therefore, the butt face of the steel strip 2 is attracted and the two butt faces are brought into tight contact with each other. The gapless butting is thus executed.

Title: Dielectric separation method of semiconductor material
Inventor: TARUI YASUO
IPC: H01L21/76
Filed: 1978-05-10
Abstract: PURPOSE: To subject an IC to dielectric separation minutely by utilizing than an oxidation speed becomes high when atom arrangement is disturbed in respect to semiconductor crystal.  
     CONSTITUTION: Epi-thin film 2 of p-type single crystal is provided on sapphire substrate 1, and ions are injected vertically through SiO 2  mask 3 to form injection layer 7 up to the approximately half depth of layer 2. Next, SiO 2  8 which reaches the surface of substrate 1 is formed by wet-type oxidation. Oxidation etching is small in the side face of an element forming layer due to oxidation speed difference, and no step is generated between the single crystal part and dielectric separation film 8, so that a flat substrate can be formed. Film 8 on the surface is removed selectively, and gate oxide film 12 is formed, and the gate electrode of poly-Si is used as a mask to form N-type layers 9 and 11. Further, the surface is covered with PSG 14 to form Al electrodes 15 and 16 selectively. Thus, an IC device can be subjected to insulation separation minutely in a simple process.

Title: Production of fiber reinforced thermoplastic resin sheet
Inventor: TABATA HIRONORI
IPC: B32B5/00
Filed: 1990-03-05
Abstract: PURPOSE:To smoothly insert a netlike facing while uniformly holding the fitting pitch of a net and to enable continuous forming by inserting the netlike facing between two sheets of fiber material impregnated with resin and heating this netlike facing and contact-bonding the netlike facing with the pinch rollers when powdery thermo plastic resin is in a semimelted state and thereafter heating the netlike facing until the powdery thermoplastic resin becomes a melted state and contact-bonding it. CONSTITUTION:For example, the admixture of vinyl chloride resin is introduced into a fluidized bed 30 at the prescribed amount. For example, eight pieces of glass roving are arrayed to the lengthwise direction and introduced into the fluidized bed 30. While the glass roving is split therein, it is blown up by air pressure and impregnated with powdery vinyl chloride resin 12 being in a floating state. Two sheets of fiber material 10a impregnated with resin are produced. When thermoplastic resin is in a semimelted state, e.g. a glass net is inserted between this two sheets of fiber material 10a impreg nated with resin. These are passed through pinch rolls 40 and thermally contact-bonded. Successively these are passed through the heated contact-bonding rolls 50 and contact- bonded by completely melting resin. While these are cooled by the cooled pinch rolls 60, these are pulled out therefrom. The fiber reinforced thermoplastic resin sheet 10 is obtained as a wound heavyweight body.

Title: Cooling type photoelectric converter
Inventor: SHINOHARA KOUJI
IPC: H01S5/022
Filed: 1980-04-24
Abstract: PURPOSE:To enable the ready prevention of the fluctuation of an optical axis of a photoelectric converter by supporting a partial optical system and hence a lens at a part of a vibrating member. CONSTITUTION:A recess part 1a and male screws 2 are formed at a copper block 1, and a laser element 3 is mounted on the block 1. A germanium (Gb) sphere 4 engaged in the recess part 1a serves as a lens for converting the dispersed light indicated by (a) and radiated from the laser element 3 into a parallel beam indicated by (b). The block 1 is mounted on a cold head in a vibrating member (not shown) using holes, and the laser element 3 is cooled by this mounting. Since the Gb sphere 4 and the laser element 3 are integrated by the block 1, the Gb sphere 4 does not serve as the flucrum of the optical axis 15, even if both vibrates together to cause the optical axis 15 to be fluctuated. Thus, the vibration of the parallel beam occurred at the remote distance of several hundreds meters does not vary from the  degree of the vibrating of the optical axis 15, and can be ignored.
