Title: Dye laser apparatus oscillating in multiple wavelength
Inventor: SHIMADA MASAYOSHI
IPC: H01S3/20
Filed: 1986-01-29
Abstract: PURPOSE:To make it possible to oscillate multiple wavelengths with one set and to display power in analysis, extraction, splitting and the like, by arranging a plurality of resonators having different resonance frequencies around a coloring matter cell on different light paths, and simultaneously oscillating lasers having the different frequencies. CONSTITUTION:A coloring matter cell D is excited with external pumping light F through a condenser lens E. A four-wavelength simultaneously oscillating dye laser is composed of four resonators so as to hold the coloring matter cell. In this constitution, the resonators are arranged so that angles between them are slightly changed and so that their optical axes are not deviated from an optical active part when the pumping light is converged in the coloring matter cell D. The resonators are constituted by output mirrors G1-G4 and gratings A1-A4, respectively. Beam expanders C1-C4 for preventing thermal damage of the gratings and etalons B1-B4 for narrowing the bandwidths of the oscillated wavelengths are provided on the optical axes as required. As output lights H1-H4, oscillated lights, which are turned to wavelengths lambda1-lambda2 determined by the conditions of the respective resonators, are obtained. For the coloring matter cell (D), rhodamine 6G is used, which has wide light emitting spectrums and high oscillating efficiency.

Filed: 1989-01-25
Abstract: PURPOSE:To obtain the catalyst which has excellent heat resistance and effectively cleans the harmful components in exhaust gases by incorporating cerium dioxide and barium stannate into a catalyst component-contg. coating layer or other coating layers.

Title: Semiconductor device and its manufacture
Inventor: WATANABE TOKUO
IPC: H01L29/74
Filed: 1995-02-03
Abstract: PURPOSE: To enable high breakdown strength and large current to be obtained by making an average concentration of impurities of a third semiconductor layer in a first region less than that in a second region and making a second main electrode come into contact with the third semiconductor layer between the first region and the second region. CONSTITUTION: A first main electrode 5 is provided in a first semiconductor layer 2 and a second main electrode 7 is provided in a fourth semiconductor layer 4. With respect to a first semiconductor region A adjacent to the edge of a semiconductor substrate 10 and a second region B inside the first region A, the first region A contains less average concentration of impurities in a third semiconductor layer 3 than the second region B. Also, the second main electrode 7 comes into contact with the third semiconductor layer 3 between the first region A and the second region B. As a result, trigger sensitivity of a thyristor part in the first region A decreases. This enables the concentration of impurities of the third semiconductor layer 3 in the first region A to decrease and dielectric strength to improve.  Also dielectric strength characteristics and the characteristics of a conducting region are improved by adjusting them individually, thus simultaneously realizing high dielectric strength and large current.

Title: Coating liquid for thermal transfer sheet
Inventor: MOMOSE HIROO
IPC: B41M5/382
Filed: 1991-01-18
Abstract: PURPOSE:To provide a coating liquid for a thermal transfer sheet which enables even a thin coat to demonstrate an excellent anti-static function.

Fine wax particles, hardly compatible with a resin, are present as such in the form of particles. During drying process after application, numerous voids generate in the film of the undercoat layer due to the defoaming action of solvent vapor. Therefore, it is presumed that the static electricity can be easily discharged into the atomosphere due to the presence of air pores formed by these voids.

Title: Bonding method of film of synthetic resin, fibrin derivative, etc.
Inventor: OOSAKI TAKEO
IPC: B29C55/00
Filed: 1981-02-09
Abstract: PURPOSE: To obtain a plate sheet poor in proportion detective, short of curls and useful to computer cards, etc. by a method wherein films of synthetic resin and fibrin derivatives, etc. which are heated and oriented are laminated with low- temperature curing adhesives at a specific temperature.  
     CONSTITUTION: In laminating films of synthetic resin, fibrin derivatives, etc. which are heaed and oriented, a thoroughly uncurled plate sheet is formed when the films are treated with low-temperature curing adhesives (such as mixed solution of polyester type urethane and isocyanate, or the like) at temperature of 50°C or less. In this manner, since general-purpose oriented film of synthetic resin begins to shrink around 50°C, the films are cured with low-temperature curing adhesives almost at an ordinary temperature and an uncurled laminated sheet of synthetic resin may be obtained at a remarkably reduced proportion defective.
