Patent number: 5332950Abstract: A driver circuit for a display device, in which first and second clock pulse generator circuits generate first and second clock pulses to a gate circuit for allowing the first clock pulse to pass when the first and second clock pulses are a high level, and by the output of the gate circuit, a combination of a transistor and an inductance generate a high voltage pulse. The high voltage pulse is rectified in a triple voltage rectifying circuit to output a high voltage output for driving the display device such as EL elements, and the high voltage output can be reset by a low frequency pulse output from a discharge circuit. As a result, no inverter is required, and a small-sized and light-weighted driver circuit is achieved with a long luminescence life of the EL elements and without noises offensive to the ear.Type: GrantFiled: September 25, 1992Date of Patent: July 26, 1994Assignee: NEC CorporationInventors: Motoyoshi Komoda, Minoru Katsumata

Patent number: 4868816Abstract: A polling communication method which asks whether or not there is a request with data from a range of answer requesting terminals. A request is determined by a binary looking-up to terminals by a center. The center and the terminals are connected through a common signal transmission line, replying to the center that there is a request with a self-address to the requesting terminal. There is a further reducing of the range of answer requesting terminals by sequentially determining, according to a binary looking-up to specify one of the requesting terminals when a collision of the requests occurs between the terminals at the replying time. The center then asks the content of the request to the specified terminal. Thus, this method can process requests at a high speed, not only when the rate of requests of terminals is low but also when the rate of requests of terminals is high and often collide.Type: GrantFiled: January 12, 1988Date of Patent: September 19, 1989Assignees: The Furukawa Electric Co. Ltd., Pioneer Electronic CorporationInventors: Minoru Katsumata, Hisaharu Yanagawa, Kousaku Ohta, Katsuzou Inao, Koh Ichinowatari
