Publication number: 20050152731Abstract: A guide wire includes a wire body having a first wire disposed at a distal end thereof and a second wire joined to a proximal end of the first wire. The first wire and the second wire are preferably joined to each other by welding, providing a layer joint therebetween. The joint is of a curved shape, particularly a convex curved shape that is convex toward the proximal end of the wire body. In the joint, at least one component (e.g., Ti) of the material of the first wire decreases toward the proximal end and at least one component (e.g., Fe) of the material of the second wire decreases toward the distal end.Type: ApplicationFiled: December 17, 2004Publication date: July 14, 2005Applicant: Terumo Kabushiki KaishaInventors: Katsuro Mishima, Yutaka Itou, Hiraku Murayama, Hideo Satou

Patent number: 6850219Abstract: A display device is constituted by a display module which determines a plurality of pieces of pixels as belonging to one block unit, selects the plurality of pixels in each block unit at the same time and displays a picture image by adding one or a plurality of specific patterns each having different spatial frequencies of each block unit; a display control unit which controls the display module; a picture image signal generation unit which generates picture image signals; and a computing circuit which generates the specific patterns each having different spatial frequencies while weighting the same based on the picture image signals for every block unit. Thereby, a display device which reduces the signal clock frequency as well as increases the signal writing time, enhances the opening rate of an LC panel and permits a highly fine display and a high speed motion picture display, is obtained.Type: GrantFiled: May 25, 2001Date of Patent: February 1, 2005Assignee: Hitachi, Ltd.Inventors: Tetsuya Aoyama, Shinichi Komura, Ikuo Hiyama, Tsunenori Yamamoto, Yoshiyuki Kaneko, Mitsuji Ikeda, Osamu Itou, Hideo Satou, Shoichi Hirota

Patent number: 6819317Abstract: A liquid crystal display wherein display is performed based on the fact that an a.c. voltage is applied to a liquid crystal layer when a switching element establishes a connection between a display electrode and a common electrode, and the a.c. voltage is not applied to the liquid crystal layer when the switching element releases the connection between the display electrode and the common electrode. A state of the switching element changes from connection between the display electrode and the common electrode to release of the connection under a condition that respective voltages of an opposite electrode, the display electrode, and the common electrode are made substantially the same, the condition being produced by stopping an a.c. voltage applied to the opposite electrode.Type: GrantFiled: October 20, 2000Date of Patent: November 16, 2004Assignee: Hitachi, Ltd.Inventors: Shinichi Komura, Yoshiro Mikami, Hideo Satou, Minoru Hoshino
