Patent number: 7750064Abstract: An antibacterial measure using titanium oxide includes mixing titanium oxide in a resin to form a coating resin, and then coating a key surface with the coating resin. This method requires formation of a coating layer on a resin molding and thus increases the number of the production steps and cost. Furthermore, in the method, a coating film containing an antibacterial agent is scraped off light by little at each time of keying, and thus the film is finally completely removed to lose its antibacterial function. A conceivable measure against this includes directly mixing a resin and an antibacterial agent. However, titanium oxide used as an antibacterial agent degrades a raw material resin. It has recently be thought that photocatalytic apatite as a substitute for titanium oxide also causes chalking, and an antibacterial coating layer has been formed on a surface of a resin molding.Type: GrantFiled: January 5, 2006Date of Patent: July 6, 2010Assignee: Fujitsu LimitedInventors: Masato Wakamura, Noriyasu Aso

Publication number: 20090223407Abstract: A surface-conditioning composition can form a denser phosphate coating film having more satisfactory coating weight on the surface of a metal material compared to a conventional one and, therefore, can reduce the electrolytic corrosion of a metal material during a chemical conversion treatment, form a chemical conversion coating film having a satisfactory coating weight even when applied to a hardly convertible metal material (e.g., an aluminum metal material, a high tensile strength steel plate), improve the productivity rate of the chemical conversion treatment, resulting in the reduction of the time required for the chemical conversion treatment, and enables a metal phosphate particle to be dispersed in a surface-conditioning solution highly stably. This composition includes a particle of a phosphate of a bivalent or trivalent metal and has a pH value ranging from 3 to 12. The particle has a D50 value of 3 ?m or less.Type: ApplicationFiled: August 21, 2006Publication date: September 10, 2009Inventors: Toshio Inbe, Masahiko Matsukawa, Kotaro Kikuchi
