Patent number: 7787915Abstract: In a folding mobile radio device, a gain is lowered considerably in its close state under such a condition that an upper case is excited directly in its open state to aim at a wide band and a high gain is used as an antenna. A folding mobile radio device includes a first case, a second case, a jointing portion for connecting the first case and the second case to open/close, a conductor element arranged in the first case, and a feeding element arranged in the second case. Then, in an open state via the jointing portion, the conductor element and the feeding element come close to each other and are coupled magnetically at a time of feeding a power whereas, in a close state via the jointing portion, the conductor element and the feeding element are apart from each other rather than the open state and are not coupled magnetically at a time of feeding a power.Type: GrantFiled: July 12, 2005Date of Patent: August 31, 2010Assignee: Panasonic CorporationInventors: Hiroyuki Uejima, Yutaka Isoda, Nobuharu Mashima, Masayoshi Hirai, Nobuhiro Iwai, Yutaka Saitoh, Kenichi Maeda

Publication number: 20080300028Abstract: In a folding type portable wireless unit, gain deteriorates sharply upon closure, in the case where an upper case is oscillated directly at the time of opening and used as an antenna in order to attain a wide band and a high gain. The folding type portable wireless unit comprises a first case, a second case, a coupling part for coupling the first and second cases to be opened/closed, a conductor element arranged in the first case, and a power supply element arranged in the second case. In the open state brought by the coupling part, the conductor element and the power supply element approach closely to each other and can be coupled electromagnetically at the time of power supply. In the closed state brought by the coupling part, the conductor element and the power supply element separate from each other as compared with the open state and they are not coupled electromagnetically at the time of power supply.Type: ApplicationFiled: July 12, 2005Publication date: December 4, 2008Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Hiroyuki Uejima, Yutaka Isoda, Nobuharu Mashima, Masayoshi Hirai, Nobuhiro Iwai, Yutaka Saitoh, Kenichi Maeda

Patent number: 5404311Abstract: The present invention relates to a delay time optimizing method of optimizing delay times and a method of optimizing delay times in an LSI equipped with latch circuits at its input and output. The method divides a plurality of logic circuits from a combinatorial circuit located among latch circuits for outputting data related to input data in response to clocks, calculates the delay time of a path between each of the latch circuits at end points and each of the latch circuits at starting points, performing the weighting related to the delay time on each of the distinguished logic circuits located between each of the starting points and each of the end points for each path, and calculates a relative index for changing the delay time for each logic circuit.Type: GrantFiled: June 15, 1993Date of Patent: April 4, 1995Assignee: Fujitsu LimitedInventor: Yutaka Isoda
