Patent number: 7560998Abstract: 1st to nth pairs of transistors (n=an odd number) are connected in parallel, and each pair of transistors has an upper transistor and a lower transistor connected in series. A point between the upper transistor and the lower transistor of a preceding pair of transistors is connected to a gate of the lower transistor of a subsequent transistor, and the point between the upper transistor and the lower transistor of nth pair of transistors is connected to the gate of the first lower transistor. A capacitor is inserted between the lower transistor and a direct power source. A current regulating circuit connected to gates of the upper transistors, wherein the current regulating circuit supplies a gate voltage to each gate of the each upper transistor.Type: GrantFiled: November 27, 2006Date of Patent: July 14, 2009Assignees: Kabushiki Kaisha Toyoto Chuo Kenkyusho, Denso CorporationInventors: Norikazu Ohta, Yoshie Ohira, Yasuaki Makino, Hiromi Ariyoshi

Patent number: 6259423Abstract: For use in a display device, a simple-matrix-drive-type luminescent panel is formed by stacking a dielectric mirror layer, a transparent electrode, a hole transport layer, a luminous layer, and a metal electrode on a glass substrate, wherein the transparent electrode is formed as a plurality of stripes equally spaced apart a specified distance from each other, and the metal electrode is formed as a plurality of stripes equally spaced apart a specified distance from each other and arranged at right angles with the transparent electrode stripes, and pixels are formed at intersections of the metal electrodes and the transparent electrodes and wherein in order for the pixels of the panel to emit light to display information, the application of a voltage to the pixels is controlled by selection of the electrodes according to information. This luminescent panel contributes to reductions in size and weight of the display device.Type: GrantFiled: August 17, 1998Date of Patent: July 10, 2001Assignee: Kabushiki Kaisha Toyoto Chuo KenkyushoInventors: Shizuo Tokito, Yasunori Taga

Patent number: 5129010Abstract: A system for measuring three-dimensional shapes and dimensions includes: an imaging unit which faces an object with shape changes on the surface and images by means of a TV camera the slit line formed on the object surface by projecting slit light from a slit light source at a fixed angle; and a surface feature extraction member for extracting features representing the shape changes of the object surface, based on the changes of the XYZ coordinate values of the object surface detected by triangulation based on the centroid position of the intensity distribution of the slit line image corresponding to the scanning lines from the TV camera. Based on features thus extracted, the surface shape of the object can be measured rapidly with high precision.Type: GrantFiled: June 15, 1990Date of Patent: July 7, 1992Assignee: Kabushiki Kaisha Toyoto Chuo KenkyushoInventors: Kazunori Higuchi, Osamu Ozeki, Shin Yamamoto

Patent number: 4902576Abstract: A high temperature sliding element is provided with a metallic film formed of any one of metals Ni, Mn, Cr, Fe and Co, and alloys of these metals on a sliding surface of a substrate of carbide ceramics or nitride ceramics in accordance with physical vapor deposition. When the substrate and a sliding counterpart ceramic member are slid in a high temperature atmosphere 500.degree. C. or higher with the metallic film intervening therebetween, wear due to sliding motion between the substrate and the counterpart ceramic member can effectively be reduced. The metallic film forms an oxidized sliding surface layer at the high temperature.Type: GrantFiled: October 16, 1986Date of Patent: February 20, 1990Assignee: Kabushiki Kaisha Toyoto Chuo KenkyushoInventors: Yoshio Shimura, Yoshiyuki Mizutani, Akio Isogai

Patent number: 4202705Abstract: A method and treating material are presented for forming a mixed carbide layer of Va-Group elements on the surface of a carbon-containing ferrous-alloy material. The molten bath is made by introducing one or more oxides of Va-Group elements and one or more metals or alloys of Va-Group elements (other than the elements forming the oxides) into a molten bath composed of boric acid, a borate or a mixture thereof. The mixed carbide layer formed on the surface of the article is very smooth, wear resistant and corrosion resistant.Type: GrantFiled: July 3, 1978Date of Patent: May 13, 1980Assignee: Kabushiki Kaisha Toyoto Chuo KenkyushoInventors: Noboru Komatsu, Tohru Arai, Hinonori Fujita
