Patent number: 8872808Abstract: A first receiver receives a clock. A second receiver receives a differential type image signal. An image signal receiving unit performs sampling the differential type image signal by the clock, and generates an image signal driving an electro-optic device. A third receiver receives a time multiplexed control signal. A reception buffer performs sampling of the time multiplexed control signal by the clock and the stores the time multiplexed control signal. A driving control unit performs a driving control of the electro-optic device on the basis of the stored time multiplexed control signal.Type: GrantFiled: March 9, 2012Date of Patent: October 28, 2014Assignee: Seiko Epson CorporationInventors: Katsutoshi Ueno, Akira Morita

Publication number: 20050041488Abstract: To reduce vertical crosstalk and thereby enhance or improve image quality in an electro-optical device employing time-division driving. In a predetermined period, a corrective voltage Vamd with a predetermined voltage level and time-series data voltages V(1,1) to V(3,1) are outputted to an output line DO1. The corrective voltage Vamd is applied simultaneously to data lines X1 to X3 connected to the output line DO1. The time-series data voltages V(1,1) to V(3,1) are time-divisionally separated into segments and the segmented data voltages V(1,1) to V(3,1) are allocated to any of the data lines X1 to X3.Type: ApplicationFiled: July 16, 2004Publication date: February 24, 2005Applicant: Seiko Epson CorporationInventors: Akihiko Ito, Katsutoshi Ueno

Patent number: 5783794Abstract: The present invention relates to a resistance welding method suitable for use in spot welding between a steel-base metal sheet, which has been plated for rust prevention purposes, and an aluminum-base metal sheet and aims to permit a current to flow at a high density across the plated steel sheet and the aluminum-clad steel sheet, thereby realizing high-quality welding.An aluminum-clad steel sheet comprised of a steel layer having projections and an aluminum layer is interposed between the plated steel sheet and the aluminum-base metal sheet to be welded to each other. An electrode is energized by a predetermined weld current from an alternating power supply. The current path is limited to the area of the projections, and metallic melt formed by melting of the plating is accommodated between the projections, preventing the current-carrying area from being increased.Type: GrantFiled: August 11, 1997Date of Patent: July 21, 1998Assignees: Nippon Steel Corporation, Toyota Jidosha Kabushiki KaishaInventors: Hatsuhiko Oikawa, Yasuo Takahashi, Tohru Saito, Yutaka Okuda, Kazuo Narita, Fuminori Matsuda, Katsutoshi Ueno, Goro Watanabe
