Patent number: 9778887Abstract: A printer switches between and uses plural communication units according to the operating mode, can switch the operating mode appropriately to the operating conditions, and can improve power conservation. The printer has a network control unit with a first communication unit configured to communicate in a first operating mode; and a main control unit having a second communication unit configured to communicate in a second operating mode. The main control unit limits the power supply to the first communication unit in the second operating mode; and the second communication unit determines whether or not to go to the first operating mode based on content of data received in the second operating mode.Type: GrantFiled: September 30, 2015Date of Patent: October 3, 2017Assignee: Seiko Epson CorporationInventors: Tsutomu Kasai, Susumu Shiohara

Patent number: 7986289Abstract: An object of the invention is to repair a drain signal line easily. Each region enclosed by two gate signal lines adjacent to each other and two drain signal lines adjacent to each other that are formed on the liquid-crystal-side surface of one of transparent substrates that are opposed to each other with a liquid crystal interposed in between is made a pixel region. Each pixel region is provided with a switching element that is driven being supplied with a scanning signal from one of the two gate signal lines and a pixel electrode that is supplied, via the switching element, with a video signal from one of the two drain signal lines. A repair conductive layer is formed so as to be contained in each drain signal line when viewed perpendicularly with an insulating film interposed in between.Type: GrantFiled: January 7, 2008Date of Patent: July 26, 2011Assignee: Hitachi, Ltd.Inventors: Yuuichi Hashimoto, Tsutomu Kasai
