Publication number: 20010002757Abstract: Windmill generator sets, each including a windmill and a generator driven by the windmill, are installed on a floating body floating on water. The floating body is formed as a triangular truss structure. Each side of the triangle of the floating body is formed by a hollow beam having a rectangular cross section. The windmill generator sets are disposed on the floating body at the respective corners of the triangle. The distance between the centers of windmills, adjacent to each other, is set at a value smaller than four times, preferably smaller than two times, the diameter of the rotors of the windmills. By setting the distance between the centers of the windmills at a value smaller than four times of the rotor diameter, the construction cost of the floating body can be reduced without any accompanying reduction in the power generation efficiency of the windmill generator sets, whereby the unit power generating cost of the plant can be reduced.Type: ApplicationFiled: December 5, 2000Publication date: June 7, 2001Applicant: Mitsubishi Heavy Industries, Ltd.Inventors: Akihiro Honda, Toru Saito

Patent number: 6106681Abstract: The present invention provides an ITO sputtering target and a method of cleaning the target. ITO ground powder which is deposited on a surface of the target requires removal to increase the cleanness of the target surface. This prevents the production of nodules caused by sputtering in order to restrain abnormal discharge and prevent the production of particles. Particles deposited on a sputtered surface of an ITO sintered target are removed by subjecting the sputtered surface to multiple-oscillation ultrasonic washing, or alternatively, by sticking an adhesive tape to the sputtered surface, sufficiently rubbing the tape against the surface, and then peeling the tape off the surface. Both methods result in 400 or fewer deposited particles of 0.2 .mu.m or more average particle diameter being present in a 100 .mu.m.times.100 .mu.m area of the sputtered surface.Type: GrantFiled: October 13, 1998Date of Patent: August 22, 2000Assignee: Japan Energy CorporationInventors: Toru Saito, Yoshikazu Kumahara, Katsuya Kuboyama

Patent number: 5345053Abstract: A method of and apparatus for supplying power during EDMing in which reverse polarity pulses are used to inhibit electrolytic activity. A main voltage pulse of a certain polarity and an auxiliary voltage pulse, preceding the main voltage pulse of the same or reverse polarity, are applied across a machining gap during the on time of a main gate signal and until a discharge is detected. The ratio of the number of auxiliary voltage pulses of regular polarity to those of reverse polarity is set to a desired value depending upon machining conditions, to thereby obtain a good compromise between the conflicting requirements of achieving a high machining rate, while inhibiting undesirable electrolytic activity.Type: GrantFiled: August 25, 1993Date of Patent: September 6, 1994Assignee: Sodick Co., Ltd.Inventors: Yuji Kaneko, Shinji Ito, Toru Saito
