Patent number: 11967838Abstract: An auxiliary power receiving device includes a power receiving unit, a notification unit, and a notification controlling unit. The power receiving unit receives power from a power transfer signal, which is used to supply power from a power transmitting device to a power receiving device. The notification unit may be provided on a main surface of a plate-shaped member. The notification controlling unit controls a notification performed by the notification unit in accordance with a power reception condition of the power transfer signal at the power receiving unit.Type: GrantFiled: December 8, 2022Date of Patent: April 23, 2024Assignee: TOYODA GOSEI CO., LTD.Inventors: Tomokazu Sakai, Shinichiro Fuki, Teppei Abe, Shigeo Takeda, Yuki Tokuyama

Patent number: 6295251Abstract: A timepiece dial plate comprises an upper plate (1) provided with holes (2, 4) and positioning legs (3) projecting from its lower surface so as to position the upper plate (1) relative to a movement; and a lower plate (11) provided on its upper surface with solid indices (12) to be fitted in the holes (2) of the upper plate (1) so as to protrude from an upper surface of the upper plate (1), and provided with holes (13) through which the positioning legs (3) of the upper plate (1) are extended. The upper plate (1) and the lower plate (11) are superposed so that the solid indices (12) of the lower plate (11) are fitted in the holes (2) of the upper plate (1), respectively, and protrude from the upper surface of the upper plate (1), and the positioning legs (3) of the upper plate (1) extend through the holes (13) of the lower plate (11), respectively.Type: GrantFiled: July 12, 1999Date of Patent: September 25, 2001Assignee: Seiko Kabushiki KaishaInventors: Shigeo Sakai, Katsuhiko Ishiguro, Masami Matsuzaki

Patent number: 5517757Abstract: A stacked heat exchanger includes separate flow paths 54 and 55 which are formed by corrugated inner fins 52 and 53, disposed in chambers 48 and 49 of a flat tube 41, and also separate U-shaped flow paths 56 are formed at the U-turn portion 50 to make the flow of refrigerant smooth, increase the area of flow paths, and eliminate the stagnation of refrigerant at the U-turn portion 50. The separation of refrigerant into two phases of gas and liquid due to centrifugal forces at the U-turn portion 50 is limited to the inside of each divided U-shaped flow path 56, thereby the distribution of the gas and liquid phases can be decreased. Also disclosed is a method of manufacturing a stacked heat exchanger, in which the reliability of flat tube 41 is improved, and the leakage of refrigerant is prevented.Type: GrantFiled: August 22, 1994Date of Patent: May 21, 1996Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Masateru Hayashi, Hiroshi Iokawa, Shigeo Sakai

Patent number: 5191579Abstract: A ring network switching apparatus connects a plurality of communication nodes by a duplex ring type transmission line. Respective communication nodes autonomously vary respective connection state by respective transmission line switching means based on the control data received from the control data receiving unit. Respective communication nodes transmit the control information designating a new transmission line state from the control information transmission unit. Thereby, respective communication nodes autonomously recover its failure and perform a re-construction of a network without an aid of a parent station. Further, the transmission data from the communication node is outputted to both transmission lines through a hybrid output section. Thus, respective communication nodes merely observe the state of the transmission line on the receiving side and switch the receiving switching means based on the observation.Type: GrantFiled: June 18, 1990Date of Patent: March 2, 1993Assignee: Fujitsu LimitedInventors: Akihiro Matsushita, Shinya Takemura, Toshio Watanabe, Shigeo Sakai, Nobuo Fukuda

Patent number: 4264373Abstract: A method of refining beet juice containing a colorant wherein the beet juice is contacted with an adsorbent composed of a dehydrated solid of a coprecipitated substance formed by insolubilizing metallic compounds in an aqueous solution. The adsorbent contains either a calcium or magnesium compound and also either an aluminum or iron compound. The process is conducted in a temperature range of 40.degree.-100.degree.

Patent number: 4009337Abstract: A small scale electronic telephone exchange system of stored program control type having a plurality of trunks and a central computer has been disclosed. The trunks function to process the real time operation and, therefore, the central computer does not need to operate on a real time basis. The central computer always scans the condition of the trunks and the subscriber's telephone terminals and, upon detecting the change of said condition, it analyzes said change and performs the necessary process for said change. The present exchange system provides many new services but the cost of the system is reasonable.Type: GrantFiled: October 10, 1974Date of Patent: February 22, 1977Assignee: Oki Electric Industry Company, Ltd.Inventors: Shigeo Sakai, Akira Ogishima, Akira Imada, Tetsuya Matsuno, Kazuo Suzuki, Susumu Sugou
