Title: Production of vinyl polymer
Inventor: SHIRAI NOBUYOSHI
IPC: C08F2/00
Filed: 1983-12-23
Abstract: PURPOSE:To obtain an odorless vinyl polymer of a low content of residual vinyl monomer, by polymerizing a vinyl monomer by a suspension polymerization process and distilling off the medium and unreacted residual vinyl monomer from the polymer suspension after the reaction. CONSTITUTION:A vinyl monomer such as styrene, butadiene or ehtyl acrylate is polymerized by a suspension polymerization process in the presence of a polymerization initiator (e.g., azobisisobutyronitrile), a stabilizer (e.g., methylcellulose), etc. After completion of the polymerization reaction, the formed polymer suspension is distilled by atmospheric or vacuum distillation to remove the medium and unreacted residual vinyl monomer to thereby obtain the purpose vinyl polymer of a low content of residual vinyl monomer. The temperature in the atmospheric distillation is suitably at least Tg-50 deg.C, wherein Tg deg.C is the glass transition point of the formed vinyl polymer.

IPC: C04B37/00
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To obtain a binder for AlN sintered products, capable of highly enhancing the air tightness and binding strength of a bound portion by mixing YAG powder with AlN powder, calcining the mixture and subsequently crushing the calcination product into particles having particle diameters of a specific value or less. SOLUTION: This binder for AlN sintered products is obtained by mixing 100 pts.wt. of YAG (Y3 Al5 O12 ) powder having an average particle diameter of <=50 μm with 30-150 pts.wt. of AlN(aluminum nitride) powder in a solvent, drying the mixture, granulating the dried mixture, calcining the granules at a temperature of 1,500-1,850 deg.C in the atmosphere of nitrogen gas and subsequently crushing the calcined granules into particles having particle diameters of <=100 μm.  The AlN sintered products are bound to each other by kneading the binder in an organic solvent, coating the obtained paste on the binding portions of the AlN sintered products, or forming the binder into a sheet-like product, disposing the sheet-like product on the binding portions of the AlN sintered products, and subsequently thermally treating the superposed AlN sintered products at a temperature exceeding 1,850 deg.C in the atmosphere of nitrogen gas. The binding of the AlN sintered products with the binder gives a volume contraction coefficient of <=10% on the sintering, a porosity of <=5% in the bound portion, and a binding strength of >=50 Mpa.

IPC: H01L31/04
Filed: 1988-09-27
Abstract: PURPOSE:To restrain irregularities from occurring on the surface of a film as well as to improve it in adhesion to a substrate so as to obtain an amorphous solar cell which is high in efficiency and reproducibility by a method wherein the film in contact with the substrate is formed in an n-type two-layered film structure composed of fine crystal silicon and amorphous silicon which are formed in film in this order. CONSTITUTION:An n-type layer 7 in contact with a metal substrate 41 is composed of a fine crystal silicon layer 71 and an amorphous silicon layer 72. Therefore, the n-type layer 71 becomes thin and the irregularities of the surface can be restricted to be small, and the adhesive strength of the fine crystal silicon layer 71 to the metal substrate 41 becomes large as compared with the layer 7 formed of only amorphous silicon. As the layer 7 formed of only a thin fine crystal silicon layer 71 is insufficient in properties as a solar cell, the n-type layer 72 of amorphous silicon excellent in evenness is laminated on the fine crystal silicon layer 71 to improve the layer 7 in properties and more in evenness. Therefore, a film excellent in adhesive power and evenness can be obtained and then an amorphous solar cell excellent in efficiency and reproducibility can be obtained.

The second signal reproduced by the video tape recorder 8 is inputted directly to a television monitor device 11. Thus, while the content of video recording is reproduced and displayed on the television monitor device 11, the result of survey of the program rating and a graph representing its timewise change corresponding to the picture are displayed on the picture.
