Publication number: 20050042124Abstract: A circular disc shape case 11 includes a motor rotor chamber 12, a bearing chamber 13 and a gear chamber 14 piled sequentially and being communicated with each other. A suction port 15 is connected to the motor rotor chamber 12, and a discharge port 16 is connected to the gear chamber 14, which communicate with outside respectively. A rotating shaft 18 having an end positioned in the motor rotor chamber 13 and the other end extending to the gear chamber 14. A rotor 22 is fixed around the rotation shaft 18 in the motor rotor chamber 13. A first bearing 19 is provided for supporting the end of the rotating shaft 18 in radial and thrust directions. A second bearing 20 is provided in the bearing chamber 13 for supporting an intermediate portion of the rotating shaft 18 in radial direction.Type: ApplicationFiled: July 7, 2004Publication date: February 24, 2005Applicants: Naoki Miyagi, Fukui Prefecture, Fujikura Ltd.Inventors: Naoki Miyagi, Fujio Yamamoto, Yuichi Murai, Koji Miyazaki, Futoshi Matsui, Yuji Aoyagi

Patent number: 6789491Abstract: A friction reducing ship reduces frictional resistance between the external hull plate 1 and water W by ejecting air A from the external hull plate 1 into water W to generate micro-bubbles B on the surface of the external hull plate 1. A structural feature of the ship is that micro-bubbles B are generated by creating a negative pressure region in the water W admitted in the water intake opening 2a, disposed below the waterline WL in the bow section 1a, so as to eject atmospheric air above the water into the water to generate micro-bubbles B, and discharging the micro-bubbles B together with water to the water discharge opening 2b provided in the bottom section 1b.Type: GrantFiled: March 30, 2001Date of Patent: September 14, 2004Assignee: Ishikawajima-Harima Heavy Industries Co., Ltd.Inventors: Yoshiaki Takahashi, Yuichi Murai

Patent number: 5890910Abstract: A storing unit of a communication karaoke apparatus has a newly released music file storing area, an information file storing area, a necessary information file list storing area, and the like. Information files are used for displaying information such as concert information, and advertisements of stores and goods. The information files are displayed during an intermission of karaoke performances due to music-piece files. When a new release file is downloaded, a necessary information file list is simultaneously downloaded. Based on the necessary information file list, unnecessary information files are deleted from the information file storing area, and only necessary information files among the downloaded information files are written into the information file storing area. Accordingly, only necessary information files can be always stored.Type: GrantFiled: October 17, 1996Date of Patent: April 6, 1999Assignee: Yamaha CorporationInventors: Kanehisa Tsurumi, Youji Semba, Yuichi Murai

Patent number: 5833469Abstract: A karaoke network system includes a host computer and a plurality of karaoke stations connected to the host computer via a communication line. When a new karaoke station is added to the karaoke network system or when a system program to be used by each of the karaoke stations is upgraded, a new system program is distributed from the host computer to the specified karaoke stations, Each of the karaoke stations has a first storage device for storing the new system program received from the host computer, and a second storage device that stores a system program currently executed to operate each of the karaoke stations. After rebooting each of the karaoke stations and thereafter, each of the karaoke stations is operated with the newest system program.Type: GrantFiled: March 22, 1996Date of Patent: November 10, 1998Assignee: Yamaha CorporationInventors: Emi Ito, Kanehisa Tsurumi, Yuichi Murai

Patent number: 5824934Abstract: A host apparatus stores all of music-piece files and information files, and also stores lists information files (information file lists) required for a plurality of areas where communication karaoke apparatuses are located. When music-piece files are downloaded to a communication karaoke apparatus, information files are simultaneously downloaded. Information files required for the area are determined based on the area where the communication karaoke apparatus is located, and only the necessary information files are downloaded together with the music-piece files. As a result, the operation efficiency and the communication efficiency can be enhanced. At this time, a list of information files stored in the communication karaoke apparatus is requested, and only difference information files are downloaded so that the efficiencies can be further enhanced.Type: GrantFiled: October 29, 1996Date of Patent: October 20, 1998Assignee: Yamaha CorporationInventors: Kanehisa Tsurumi, Youji Semba, Yuichi Murai
