Patent number: 8279043Abstract: An objective of the present invention is to provide a portable information terminal device capable of reducing excessive time and labor required in an authentication process. A sub-camera is started on the basis of operation to select “secret mode” by a user (FIG. 9(a)) and brought into a photographable state after completion of an initialization process, which is followed by automatically performing an authentication process (FIG. 9(b)). Therefore, it is possible to prevent troublesome photographing operation by waiting for a time course from the start of the sub-camera to reaching a photographable state, allowing reduction of excessive time and labor required in an authentication process.Type: GrantFiled: July 12, 2006Date of Patent: October 2, 2012Assignee: Sharp Kabushiki KaishaInventors: Masaaki Sasa, Hiroyasu Hamamura, Seiji Hamaguchi

Publication number: 20070225183Abstract: A lubricant is provided that can form a sufficiently thin one-molecule film surface even when it is highly polymerized. When used for a magnetic recording medium lubricant layer and/or a head slider lubricant layer of a magnetic recording device, it can make the film thickness of the lubricant layers very small, with the result that it can furnish an increased reliability to the magnetic recording device in a wide temperature-range environment without damaging the flying stability. This lubricant comprises a fluorine-containing polymer having a specific structure. Such a fluorine-containing polymer can be manufactured by reacting a compound having a specific structure and 1,3-butadiene diepoxide.Type: ApplicationFiled: March 22, 2007Publication date: September 27, 2007Applicant: FUJITSU LIMITEDInventors: Masaaki Sasa, Hiroshi Chiba, Makoto Okada

Publication number: 20070203037Abstract: A lubricant is provided that achieves a sufficiently small one-molecule-layer film thickness even when it has a high molecular weight, and has an increased reliability in a wide temperature range environment without losing the flying stability, by making the film thickness of a lubricant layer very small when it is used for the magnetic recording medium lubricant layer and/or head slider lubricant layer of a magnetic recording device. This lubricant comprises a fluorine-containing polymer, the lubricant having a relationship: Y<?1.4475X+2.815, wherein Y is a natural logarithm of diffusion coefficient at 23° C. (unit:?m2/s); and X is a viscosity at 20° C. (unit: Pas), or it comprises a fluorine-containing polymer having a particular structure, and with molecular chains between adjacent polar groups that have a number-average molecular weight of not less than 500.Type: ApplicationFiled: July 31, 2006Publication date: August 30, 2007Applicant: FUJITSU LIMITEDInventors: Hiroshi Chiba, Masaaki Sasa, Yukiko Oshikubo, Keiji Watanabe, Eishin Yamakawa, Takeshi Tokairin
