Patent number: 8932072Abstract: A charging device starts charging a battery mounted on an electrically driven vehicle in accordance with simplified operating steps. A charging supply connector is connected to a charging port mounted on a vehicle body side. The charging supply connector includes a lock lever displaceable between a locking position, for engagement with a hook mounted on the charging port, and a lock release position where the lock lever is released from the hook. The lock lever is spring-biased to the locking position. A manipulation lever is connected to the lock lever by a link, and is operable to move the lock lever between the locking position and the lock release position. When the lock lever is at the lock release position, the lock lever, the link or the lock lever and the link interferes with an operation range of a charging start switch, to prevent operation thereof.Type: GrantFiled: March 14, 2013Date of Patent: January 13, 2015Assignee: Honda Motor Co., Ltd.Inventors: Kenji Tamaki, Hiroki Ichikawa

Patent number: 8687444Abstract: A plurality of memory cells are tested in order. Each time a defective memory cell is detected by the test, error pattern information is updated based on a relative arrangement relationship between a plurality of defective memory cells, and error address information is updated based on the addresses of at least part of the plurality of defective memory cells. According to the present invention, it is possible to significantly reduce the storage capacity of the analysis memory. This allows the implementation of the analysis memory itself in the semiconductor device, in which case external testers need not include the analysis memory.Type: GrantFiled: September 28, 2011Date of Patent: April 1, 2014Assignee: Elpida Memory, Inc.Inventors: Akira Ide, Hiroki Ichikawa

Patent number: 8249637Abstract: An object of the present invention is to provide means for eliminating a transmission delay when transmitting emergency information for the sake of relief, security, or the like in a wireless device in conformity with the wireless LAN standard in which if radio waves transmitted from peripheral devices are detected, transmission has to be stopped. In a multimode wireless communication scheme having two or more communication schemes, priorities of the communication schemes are set. A high priority or low priority regarding to a message is described in a “message type” data field of a frame of a controlling channel output from the access point side to the terminal side. When the frame of the controlling channel is decrypted on the terminal side, the message type is confirmed, so that the type of a service channel used thereafter is confirmed and the channel is coupled.Type: GrantFiled: July 16, 2010Date of Patent: August 21, 2012Assignee: Renesas Electronics CorporationInventors: Tsutomu Tsuboi, Izuru Yamada, Hiroki Ichikawa
