Autor: Hitoshi Yokono, Hiroshi Yamamoto, Hiroaki Okudaira, Hiroko Takehara, Jiro Ushio, Setsuo Ando, Takashi Inoue, Toshihiko Ota
Publikováno v: Journal of the Surface Finishing Society of Japan. 49:1298-1304
The paper reports a new autocatalytic electroless gold plating bath that achieves almost neutral, low temperature bath conditions and excellent process stability without cyanide. The bath contains a thiosulfatesulfite mixed complex of Au (I) as the g

Flexural properties of moldings of rigid polyurethane made by reaction injection molding
Autor: Makoto Iida, Yasushi Miyano, Hitoshi Yokono, Masao Gotoh
Publikováno v: Polymer Engineering and Science. 26:701-707
Flexural properties of moldings made by Reaction Injection Molding (RIM), which are structural foams consisting of high density skin and low density core, were investigated by three-point bending tests. Two failure modes were observed in bending test

Highly sensitive self-developing soft X-ray resists of silicon-containing aldehyde copolymers and sensitive novolac-based composite resists containing aldehyde copolymer
Autor: Kazuo Nate, Takashi Inoue, Hitoshi Yokono, Koichi Hatada
Publikováno v: Journal of Applied Polymer Science. 35:913-921
Copolymers of aliphatic aldehydes containing a trimethylsilyl group were prepared at −78°C in toluene using diethylaluminum diphenylamide as an initiator. The copolymer depolymerized into monomeric aldehydes on exposure to soft X-rays. When the co

Large Capacity Class-H Resin Molded Transformer
Autor: R. Takeuchi, Hitoshi Yokono, S. Isobe, Y. Kihara, M. Kito Hitachi, N. Ikemoto, Shunichi Numata, K. Asakura
Publikováno v: IEEE Transactions on Electrical Insulation. :436-443
The number of dry type transformers for use in buildings and industrial plants has increased in order to meet new safety requirements in Japan which prohibit the use of PCB. Dry type transformers are grouped as conventional dry type Class-H transform

Simulation of foaming process of polyurethane integral skin foams
Autor: Susumu Tsuzuku, Yasushi Miyano, Yasuo Hira, Hitoshi Yokono, Masao Gotoh
Publikováno v: Polymer Engineering and Science. 25:959-964
This paper deals with a procedure to simulate the foaming process of polyurethane integral skin foams. The process involves heat generation by chemical reaction, heat loss through the mold, and local vaporization and condensation of the solvent. To s
