Patent number: 8675463Abstract: An optical disc driving device includes a control circuit 4 for performing a gain adjustment for each of two recording surfaces of a multilayered optical disc 1 on the basis of an FE signal in such a way as to maintain a state in which light is focused onto either of the recording surfaces, to generate a focus servo loop signal, and for generating a focus jump signal for causing either a transition from a state in which the light is focused onto one recording surface to a state in which the light is focused onto the other recording surface, or a transition in the opposite direction from a threshold set up on the basis of an amount of gain adjustment, and a focus actuator driving circuit 5 for performing either a focus jump or an operation of maintaining the state in which the light is focused.Type: GrantFiled: December 27, 2007Date of Patent: March 18, 2014Assignee: Mitsubishi Electric CorporationInventors: Hiroshi Hoshino, Nobuaki Hirai

Publication number: 20100285157Abstract: When a light and porous inorganic substance is employed in a large amount as a excipient, it is impossible in the subsequent tabletting step using a tabletting machine to supply a desired amount of the resultant powder into a mortar having a definite diameter. As a result, extremely light tablets are produced. A method of producing the tablet is characterized by including dissolving or dispersing an oily substance, a liquid substance derived from a natural product or a low-melting substance in an organic solvent, allowing a porous calcium silicate powder to adsorb and hold the solution, adding a starch and/or a saccharide thereto, granulating the obtained mixture to give granules having an appropriate loose bulk density, and then compression molding those granules to give tablets.Type: ApplicationFiled: February 20, 2007Publication date: November 11, 2010Applicant: ASAHI BREWERIES, LTDInventors: Nobuaki Hirai, Kazuyuki Ishikawa

Publication number: 20100226994Abstract: A granule comprising a carrier composed of porous calcium silicate; a functional substance which is an oily liquid or a low-melting solid and a water-soluble antioxidizing agent, which are adsorbed on the carrier; and a granulating component. The problem to be solved is to improve storage stability of a powdered or tableted functional substance, for example, vitamin A to the level causing no problem in practical use.Type: ApplicationFiled: October 3, 2008Publication date: September 9, 2010Inventors: Nobuaki Hirai, Kazuyuki Ishikawa, Yasutaka Azechi, Yoshitaka Etou

Publication number: 20040146563Abstract: Special calcium silicate and crosslinked polyvinylpyrrolidone are fed into a vessel and then a definite amount of water is added thereto. Next, the contents are agitated with an agitator attached to the vessel so that water is uniformly dispersed in the mixture of the special calcium silicate and crosslinked polyvinylpyrrolidone and is retained therein. Then the mixture is granulated while displacing the water in the mixture to a Chinese orthodox medicine extract, a crude drug extract, or an extract derived from a natural substance. Thus, a granulated product having a high content of the Chinese-orthodox medicine extract, the crude drug extract, or the extract derived from a natural substance can be obtained, which makes it possible to miniatuarize or reduce number or amount of doses of tablets each containing the Chinese orthodox medicine extract, the crude drug extract, or the extract derived from a natural substance.Type: ApplicationFiled: March 25, 2004Publication date: July 29, 2004Inventors: Nobuaki Hirai, Kazuyuki Ishikawa

Patent number: 6467678Abstract: A wire bonding method and apparatus, in which after the tail of a wire extends out of a capillary, the capillary moves to a measurement position above a tail length measuring member; the capillary descends so that the end of the tail contacts the tail length measuring member; a position of the capillary or a distance by which the capillary is lowered at the time that electrical continuity is established with the tail length measuring member is detected; and the tail length is calculated based upon a height level of the tail length measuring member, the position of the capillary before being lowered for measuring the tail, and the position of the capillary when the wire contacts the tail length measuring member, or upon the height of the capillary above the tail length measuring member before lowering the capillary for measuring the tail, and a distance the capillary is lowered.Type: GrantFiled: December 28, 2000Date of Patent: October 22, 2002Assignee: Kabushiki Kaisha ShinkawaInventors: Tooru Mochida, Tatsunari Mii, Nobuaki Hirai

Patent number: 5748585Abstract: A disc apparatus includes a readout unit, an audio signal output unit, a memory, a switch, and a controller. The readout unit reads out data from a disc wherein the data includes at least digital audio data. The audio signal output unit produces an audio signal output in accordance with the digital audio data. The memory stores the digital audio data read from the disc by the readout unit. The switch switches the digital audio data supplied to the audio signal output unit between the digital audio data stored in the memory and the digital audio data currently being read by the readout unit.Type: GrantFiled: June 17, 1994Date of Patent: May 5, 1998Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Manabu Tsukamoto, Nobuaki Hirai, Kazuhito Endo, Yoshinobu Ishida, Masayuki Ishida

Patent number: 5587978Abstract: A digital signal which is recorded on a recording medium with being encoded is duplicated to another recording medium without being decoded. An audio signal is recorded and/or reproduced using data recorded in a TOG of the recording medium. A first data signal (2-channel audio signal) is intermittently recorded on and/or reproduced from a first area of the recording medium, and a second data signal (other 2-channel audio signal) is intermittently recorded on and/or reproduced from a second area of the recording medium during a period in which the first data signal is not recorded or reproduced.Type: GrantFiled: April 15, 1993Date of Patent: December 24, 1996Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kazuhito Endo, Masayuki Ishida, Yoshinobu Ishida, Manabu Tsukamoto, Nobuaki Hirai
