Filed: 1992-08-12
Abstract: PURPOSE:To obtain a highly finished general outside plate and a highly corrosion-resistant edge by incorporating a specified gelled fine particle into a cationic electrodeposition coating and specifying the minimum melt viscosity of the coating film obtained from the coating when the film is cured. CONSTITUTION:A material having an edge is coated with a cationic electrodeposition coating A and baked. The material is then coated with a cationic electrodeposition coating B and baked. The cationic electrodeposition coating contains a cationic electrodeposition gelled fine particle obtained by dispersing the addition product of epoxy resin and amine contg. a hydrolyzable alkoxysilane group in water and intraparticle cross-linking the addition product. The minimum melt viscosity of the coating film obtained from the coating B is controlled to 10<4>-10<8>cps when the film is cured. Consequently, the edge corrosion resistance and smoothness are attained.

Inventor: HIROSE SATOSHI
IPC: H04N5/353
Filed: 1990-09-05
Abstract: PURPOSE:To have a multiplification factor of electric charge constant independently of a stored charge amount by a method wherein a surface potential control gate electrode is provided above a semiconductor region between an avalanche photodiode and a charge storing part. CONSTITUTION:A main part which constitutes an avalanche photodiode consists of a P-N junction composed of a P-type silicon substrate 21 and an N<+>-type region 22. The potential of the N<+>-type region 22 and an N<->-type region 23 around it is fixed by a surface potential under a polycrystalline silicon gate electrode 27. A voltage higher than a voltage applied to the electrode 27 is applied to a polycrystalline silicon gate electrode 25 and the potential of a silicon region beneath the electrode 25 is low against electrons and the region functions as a charge storing region. On the other hand, as charge is not stored in a silicon region beneath the electrode 27, the surface potential of the region is not varied. With this constitution, a potential difference applied to the P-N junction is not varied and its multiplication factor is constant.
