Patent number: 9704479Abstract: A speech recognition device starts to generate dictionary data for each type of name based on name data and paraphrase data, and executes dictionary registration of the dictionary data. The speech recognition device obtains text information same as text information for generating the dictionary data last time. When back-up data corresponding to the last time text information is generated, the speech recognition device executes the dictionary registration of the dictionary data generated as the back-up data. Further, a dictionary data generation device executes the dictionary registration of the dictionary data based on given name data every time the dictionary data generation device completes generation of the dictionary data based on the given name data.Type: GrantFiled: January 29, 2013Date of Patent: July 11, 2017Assignee: DENSO CORPORATIONInventors: Hideaki Tsuji, Satoshi Miyaguni

Patent number: 5682558Abstract: A camera having a zoom lens. The camera includes a shutter, an aperture and program exposure mode control. The program exposure control includes one or more reference program characteristics representing combinations of shutter speed and aperture corresponding to one or more of a portrait mode, a landscape mode and a close up mode. Each reference program characteristics define a predetermined aperture in a first range from a low shutter speed to a hand-induced vibration limit and defines a different aperture in a second range beyond the hand-induced vibration limit. One of the reference program characteristics is selected, wherein the hand-induced vibration limit is defined in accordance with a focal length of said zoom lens.Type: GrantFiled: April 7, 1995Date of Patent: October 28, 1997Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Tadayuki Kirigaya, Hideaki Tsuji, Isamu Hirai, Yasuyuki Haneishi, Masato Yamamoto, Masaaki Haga, Masashi Furuno, Akio Takahashi, Koji Sato
