Patent number: 7127229Abstract: The object of the present invention is to provide a cellular phone to be used for emergency reports that performs GPS positioning by means of remote control from an emergency report center, and transmits positional information to the emergency report center. The emergency report cellular phone according to the present invention is constituted such that when an emergency report switch thereof is depressed, a call request is made to the emergency report center. The emergency report center transmits a response signal with the result that a call link is formed between the emergency report cellular phone and the emergency report center. Following completion of the telephone call, the emergency report center transmits a position recalculation command message, by means of a DTMF signal.Type: GrantFiled: September 4, 2002Date of Patent: October 24, 2006Assignee: Uniden CorporationInventors: Yoshihiko Baba, Teruhide Kunimitsu, Kenji Sekine, Mikio Iwakuni, Katsuhiro Miyamoto, Toshiaki Yuasa, Toshihiro Takahashi, Norio Abe, Shuji Konishi, Tadashi Kogure, Jun Yoshida, Katsuya Kaneda, Isao Ohki, Masaru Akiyama, Masato Suzuki

Publication number: 20060201202Abstract: Mist of titanium element-containing liquid particles is adhered to the surface of a glass substrate having a surface compressive stress of at most 10 MPa so as to coat the surface of the glass substrate with the liquid. Next, the liquid-coated surface is heated up to a maximum temperature of from 550 to 700° C. and then cooled under a specific condition, thereby making the resulting glass sheet have a surface compressive stress of from 20 to 250 MPa. The process gives a glass sheet coated with a titanium oxide thin film having a photocatalytic function. The resulting titanium oxide thin filmhad good adhesiveness andabrasion resistance. Since its surface has a micro-roughness, the glass sheet has neither interference color nor interference fringes and has good transparency.Type: ApplicationFiled: March 24, 2003Publication date: September 14, 2006Inventors: Takeshi Nakajima, Takeshi Yuuki, Masaru Akiyama, Keizo Masada
