Patent number: 8098836Abstract: When the frequency of an engine rotation signal reaches a predetermined frequency, a comparator of a switching unit outputs a switching control signal to selectors and a filter coefficient updater. Based on the switching control signal, the selector switches from a connection between one memory and a corrector to a connection between another memory and the corrector, thereby changing the transfer characteristics C^rr of the corrector from C^11 to C^10. Based on the switching control signal, the selector switches from a connection between one ADC and a filter coefficient updater to the connection between another ADC and the filter coefficient updater, thereby supplying the filter coefficient updater with an error signal, rather than an error signal.Type: GrantFiled: December 3, 2007Date of Patent: January 17, 2012Assignees: Honda Motor Co., Ltd., Pioneer CorporationInventors: Kosuke Sakamoto, Toshio Inoue, Akira Takahashi, Yasunori Kobayashi, Kenji Yamagata, Shinji Fukumoto

Publication number: 20070190746Abstract: An SOI substrate which has a thick SOI layer is first prepared. Then, the SOI layer is thinned to a target film thickness using as a unit a predetermined thickness not more than that of one lattice. This thinning is performed by repeating a unit thinning step which includes an oxidation step of oxidizing the surface of the SOI layer by the predetermined thickness not more than that of one lattice and a removal step of selectively removing silicon oxide formed by the oxidation. The SOI layer of the SOI substrate is chemically etched by supplying a chemical solution to the SOI layer, and the film thickness of the etched SOI layer is measured. When the measured film thickness of the SOI layer has a predetermined value, a process of chemically etching the SOI layer ends.Type: ApplicationFiled: March 23, 2007Publication date: August 16, 2007Applicant: CANON KABUSHIKI KAISHAInventors: Masataka Ito, Kenji Yamagata, Yasuo Kakizaki, Kazuhito Takanashi, Hiroshi Miyabayashi, Ryuji Moriwaki, Takashi Tsuboi
