Publication number: 20140377581Abstract: A surface treatment agent composition which contains aluminum as the coating film formation component and exhibits excellent properties for removing tin ions within a treatment bath when subjecting a tin-plated steel to electrolytic surface treatment, thereby forming a coating film exhibiting excellent corrosion resistance and yellowing resistance. This surface treatment agent composition is used for subjecting a tin-plated steel or a tin-based alloy-plated steel to electrolytic surface treatment and contains aluminum ions, fluorine ions, and polycarboxylic acid. The tin ions that eluted from the tin-plated steel are precipitated within and removed from the treatment bath by using this surface treatment agent composition.Type: ApplicationFiled: March 22, 2012Publication date: December 25, 2014Applicant: NIPPON PAINT CO., LTD.Inventors: Miwa Uchikawa, Masahiko Matsukawa, Tomio Hirano

Patent number: 6190728Abstract: A process for forming a functional ceramic thin film eliminating the need of high temperature annealing which has been indispensable in the conventional process is provided. This can be achieved by the process for forming a functional ceramic thin film having a crystal of a composite oxide consisting of two or more metal elements and oxygen, which comprises steps of alternately stacking seeding layers having the same crystalline structure as said composite oxide and formable at a temperature lower than the crystallization temperature of the composite oxide, and layers containing a larger amount of a specified metal element than said seeding layers, and then annealing the resultant layers to form an integral body.Type: GrantFiled: September 28, 1998Date of Patent: February 20, 2001Assignee: Yazaki CorporationInventors: Hisao Suzuki, Tomio Hirano, Tatsuya Wada

Patent number: 5111023Abstract: To remove pores and lattice defects in gold film plated on a substrate, the gold plating film is irradiated with a first laser beam to bring at least the surface of the film into almost melted condition, and then cooled in air. Further, it is preferable to anneal the melted gold surface by a second laser beam weaker than the first laser beam before air cooling, thus reducing the thickness of the gold film and therefore the material cost of electric contacts, for instance.Type: GrantFiled: July 25, 1990Date of Patent: May 5, 1992Assignee: Yazaki CorporationInventors: Kinya Horibe, Tomio Hirano, Minoru Ikeda, Hideaki Murata
