Patent number: 9194568Abstract: A lighting unit according to one embodiment includes a board, a support member, and a plurality of heat radiation fins. A light emitting element is disposed on a first surface of the board. The support member has an interior surface on which a second surface of the board that is opposite to the first surface is disposed to be in contact therewith to enable heat conduction from the board to the support member. The heat radiation fins are disposed on an exterior surface of the support member substantially parallel with each other and with a clearance between each other, and each having a flat shape that extends outwardly from the exterior surface.Type: GrantFiled: August 6, 2012Date of Patent: November 24, 2015Assignees: Toshiba Lighting & Technology Corporation, Kabushiki Kaisha ToshibaInventors: Takayoshi Moriyama, Junya Murata, Makoto Yamazaki, Yumi Hanyuda, Katsumi Hisano, Mitsuaki Kato, Masataka Shiratsuchi, Yuichiro Yamamoto

Patent number: 8773612Abstract: A light emitting module (1) comprises a module substrate (2), a light emitting diode string (31), and a sealing member (48). The light emitting diode string (31) includes light emitting diode elements (32) and bonding wires (37) which connect the light emitting diode elements (32). The light emitting diode element (32) has a pair of element electrodes (33, 34) and has a rectangular shape extending in a direction along which the element electrodes (33, 34) are aligned. The sealing member (48) is laminated on the module substrate (2) to seal the light emitting diode string (31). The light emitting diode elements (32) are arranged at intervals in a direction crossing the direction along which the element electrodes (33, 34) are aligned, and the element electrodes (33, 34) with the same polarity are aligned to be adjacent to each other in an arrangement direction of the light emitting diode elements (32) between the light emitting diode elements (32) adjacent to each other.Type: GrantFiled: February 26, 2010Date of Patent: July 8, 2014Assignee: Toshiba Lighting & Technology CorporationInventors: Tomohiro Sanpei, Kiyoshi Otani, Masahiro Izumi, Junya Murata, Akiko Saito, Yumiko Hayashida

Publication number: 20130250574Abstract: A lighting unit according to one embodiment includes a board, an insulating plate, an optical lens, and a positioning member. The board has a mounting surface on which a light emitting element is mounted. The insulating plate is disposed on the mounting surface of the board to control the reflection direction of light emitted from the light emitting element. The optical lens diverges or converges the light reflected by the insulating plate. The positioning member positions the insulating plate and the optical lens such that the insulating plate and the optical lens are located away from each other by a predetermined distance. A lighting device according to one embodiment includes a plurality of the lighting units fixed to the lighting device via a fixing frame.Type: ApplicationFiled: August 6, 2012Publication date: September 26, 2013Applicants: Kabushiki Kaisha Toshiba, Toshiba Lighting & Technology CorporationInventors: Takayoshi MORIYAMA, Junya MURATA, Makoto YAMAZAKI, Yumi HANYUDA, Katsumi HISANO, Mitsuaki KATO, Masataka SHIRATSUCHI, Yuichiro YAMAMOTO

Patent number: 4338844Abstract: A tone source circuit for electronic musical instruments, in which a unit phase coefficient corresponding to a note code required by a key depression is read out from a phase coefficient memory of a tone generating part for each time division channel; the unit phase coefficient is applied to an accumulator composed of an adder and an accumulated value storage register to obtain an accumulated value for each time division channel. A demultiplexer for taking out higher order bits of the accumulated value and supplying them as a sampled rectangular wave signal to a filter provided corresponding to each key, the filter eliminates a sampling pulse component from the sampled rectangular wave, and a mixing circuit then mixes the output from the filters.Type: GrantFiled: February 13, 1980Date of Patent: July 13, 1982Assignee: Kabushiki Kaisha Kawai Gakki SeisakushoInventor: Junya Murata
