Patent number: 7285787Abstract: A microscope has a light source that emits light to illuminate a sample, a first wavelength selection member that selectively transmits the light from the light source, a light splitter that reflects the light from the first wavelength selection member to epi-illuminate the sample and transmits the light emitted from the sample, and a second wavelength selection member that selectively transmits the light transmitted through the light splitter. The light splitter is constituted of a transparent member and a dichroic mirror coat disposed on the transparent member. The dichroic mirror coat is constituted of a stacked layer that efficiently reflects light having a wavelength selected by the first wavelength selection member and a stacked layer that reflects light on a short wavelength side from the light selected by the first wavelength selection member, light on a long wavelength side, light of the same band, or combined light.Type: GrantFiled: April 4, 2005Date of Patent: October 23, 2007Assignee: Olympus CorporationInventors: Shuhei Horigome, Tadashi Watanabe

Patent number: 7212272Abstract: An electro-optical device and an electronic apparatus are provided with reduced wiring resistance. A second wiring pattern for connecting an upper wiring connected to a mounting terminal to a first inter-substrate conducting terminal includes a base electrode. An inorganic insulating film is not attached to the sides of the base electrode. As a result, the upper wiring on each side of the base electrode and the first inter-substrate conducting terminal are electrically connected to the base electrode through the sides. The path from the mounting terminal to the first inter-substrate conducting terminal is formed in the order of upper wiring, one side of the base electrode, base electrode, the other side of the base electrode, and then the first inter-substrate conducting terminal. The second wiring pattern uses the base electrode formed of a metal film to sharply reduce wiring resistance.Type: GrantFiled: February 19, 2004Date of Patent: May 1, 2007Assignee: Seiko Epson CorporationInventors: Kazuyoshi Sakai, Tadashi Watanabe

Publication number: 20060156132Abstract: The clock cycle during the shift operation is set shorter than the clock cycle during the capture operation in the scan test circuit. For example, the clock cycle during the shift operation is set to 20 nano second, while the clock cycle during the capture operation is set to 100 nano second. The clock is fed from a LSI tester outside of the LSI through the clock terminal CLK. The cycle of the clock can be switched to synchronize with the change of the scan enable signal SCANEN by the LSI tester. The time for shift operation can be shortened in this invention, leading to the shorter scan test time.Type: ApplicationFiled: November 16, 2005Publication date: July 13, 2006Applicant: SANYO ELECTRIC CO., LTD.Inventors: Satoru Koishikawa, Tadashi Watanabe

Patent number: 6945497Abstract: A cockpit door body 10 can be opened toward a cockpit in a direction shown by arrow R1 by a crew inside a cockpit 3 by manipulating a knob on a first hinge device 40. When rapid decompression occurs in the cockpit, a mechanical pressure-sensitive device of the first hinge device 40 operates to release a bolt from a catch. By the difference in pressure between the cabin and the cockpit, the door body 10 opens in the direction of arrow R1 to thereby reduce pressure difference. When rapid decompression occurs in cabin 4, a second latch device 60 detects this pressure difference and operates mechanically to rotate a link lever 62 to release a stopper 64 from a catch 66. Flaps 30 and 32 are opened toward cabin 4 in the direction of arrow R2 by the difference in pressure between the cockpit and cabin to thereby reduce pressure difference.Type: GrantFiled: January 20, 2004Date of Patent: September 20, 2005Assignee: Jamco CorporationInventors: Fumiaki Saku, Tadashi Watanabe, Yasuo Sekikawa
