Title: Production of synthetic resin film
Inventor: IWASAKI KOUJI
IPC: B29C47/00
Filed: 1982-08-06
Abstract: PURPOSE:To facilitate the production of a resin film one of whose surfaces has stronger adhesiveness than the other, by forming a film from low-density polyethylene containing a small amount of low-MW polybutene and subjecting one surface of the film to corona discharge treatment. CONSTITUTION:A film is formed from a resin composition containing (A) 95- 99.5wt% low-density polyethylene (and/or ethylene/vinyl acetate copolymer of a vinyl acetate content of below 10wt%) and (B) 5-0.5wt% low-MW polybutene of a number average MW of about 500-3,000, by an inflation process, a T die process, or the like. Then, one of the surfaces of the film is subjected to corona discharge treatment. Just after the corona discharge treatment, the produced surface-treated film shows not so strong tackiness of the treated surface and, therefore, can be wound up easily, while after about 48hr or longer from the winding, the polybutene has migrated into the treated surface and gives strong tackiness to this surface.

Title: Optical variable wavelength filter, its production, and method for adjusting its wavelength characteristic
Inventor: MIZUTA SATOSHI
IPC: G02F1/125
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain wavelength characteristics which are less asymmetrical with respect to the center wavelength without requiring voltage application from the outside or the like by providing a means, which gives a distortion to an optical waveguide to correct a local difference in complex index of refraction of the optical waveguide, in the vicinity of the optical waveguide formed on a substrate. SOLUTION: The TE mode is excited in an optical waveguide 2 through an incidence polarizer 4a, and light is converted to a TM wave by a surface acoustic wave 8 excited through an interdigital electrode 5 in accordance with propagation in the waveguide 2, and it is emitted from the optical waveguide 2. If the difference in complex index of refraction in the optical waveguide 2 is not fixed but has a distribution in the light going direction in this process, wavelength characteristics of a filter are asymmetrical. The optical wavelength variable filter is provided with a distortion giving film 3, which gives an elastic distortion to the optical waveguide 2, as a correction means in addition to the interdigital electrode 5 which excites the surface acoustic wave 8 in the optical waveguide 2. Because of this distortion giving film 3, filter wavelength characteristics having a high lateral symmetry with respect to the center wavelength are obtained.

Title: Production of semiconductor wafer
Inventor: MORITA ETSURO
IPC: H01L21/324
Filed: 1994-05-26
Abstract: PURPOSE:To prevent the drop of breakdown strength caused by haze etc., by grinding slightly the surface of a semiconductor wafer after annealing the semi conductor wafer in a hydrogen atmosphere. CONSTITUTION:A semiconductor wafer is annealed in a hydrogen atmosphere. Then the surface of the semiconductor wafer is slightly ground for removal. When the semiconductor wafer is subject to heat treatment in a hydrogen atmosphere, the impurities adjacent to the wafer surface are diffused outwardly, thereby removing all causes for generating failures around its surface. Therefore the surface failures of the wafer can be greatly reduced. In addition, the drop of breakdown strength caused by haze, etc., can also be prevented by grinding the surface thereafter.
