Publication number: 20050235313Abstract: A program information acquisition apparatus includes a program information acquisition unit, a program information accumulation unit, and a program information acquisition determining unit. In this configuration, a start of an acquisition operation by the program information acquisition unit is determined based on an information accumulation status of the program information accumulation unit. Thus, program information distributed from a desired reception target can be accumulated as the latest information as much as possible. Since unneeded program information is not acquired, program information acquisition with high energy saving effects is made possible.Type: ApplicationFiled: March 30, 2005Publication date: October 20, 2005Inventors: Akihito Yamada, Masayoshi Murayama, Hiroshi Kida, Nozomu Kikuchi, Hideyuki Uchiyama, Takanori Harada

Patent number: 6922180Abstract: A PDP driving apparatus having a resonance driver of a PDP electrode for shortening a time required to display an image since the power-up. A power collecting capacitor included in each electrode resonance driver is charged rapidly to a predetermined potential upon power-up of the PDP driving apparatus by allowing each electrode resonance driver to drive electrodes by means of excitation. Also, while the power collecting capacitor included in the row electrode pair driver is charged, charge driving pulses in-phase and of the same polarity are applied respectively to corresponding two electrodes to drive these electrodes by means of excitation.Type: GrantFiled: May 28, 2002Date of Patent: July 26, 2005Assignees: Pioneer Corporation, Pioneer Display Products CorporationInventors: Takashi Iwami, Nozomu Kikuchi

Patent number: 5726703Abstract: A stereoscopic image display system has a left/right stereoscopic image signal generator for alternately generating left-eye and right-eye image signals at every field, a screen for projecting image light, a liquid crystal shutter. The liquid crystal shutter has a response speed of 1 ms or less, and a contrast between black and white of 100 to 1 or more at a central wavelength of an emission spectrum of a CRT in both parallel and crossing modes of the polarizing plates of the shutter, and a cell gap of 3 .mu.m or less. The screen comprises a Fresnel lens and a lenticular sheet, and the lenticular sheet is disposed in a direction so that a polarizing condition does not generate a phase difference based on the lenticular sheet.Type: GrantFiled: July 12, 1996Date of Patent: March 10, 1998Assignee: Pioneer Electronic CorporationInventors: Masataka Izawa, Kazuto Sato, Nozomu Kikuchi, Ryuji Miyazaki, Hirokazu Izumi

Patent number: 5652395Abstract: A bending sensor of the invention is formed of a flexible segment, a pressure-sensitive electrically-conductive resin film formed on the flexible segment, and a pair of electrodes to be attached to the resin film. The resin film is made of pressure-sensitive electroconductive ink and coated on the segment. The resin film has a characteristic such that an electric resistance value is reduced as a pressure on the resin film increases. When the segment is bend-formed at an inflection point by receiving an outer force, the segment provides a pressure to the resin film at the inflection point to produce an inner stress in the resin film. When the segment is bent-deformed, the electrodes output a resistance change of the resin film to thereby detect bending of the flexible segment.Type: GrantFiled: May 29, 1996Date of Patent: July 29, 1997Assignee: Hirano Electronics Co. Ltd.Inventors: Teruaki Hirano, Nozomu Kikuchi, Kazumasa Saito
