Publication number: 20220163169Abstract: A maintenance apparatus for a cryocooler includes a glovebox, a container, and a lid. The glovebox is configured to be joined to a cooling subject coupled to a cylinder of the cryocooler. The glovebox defines a first glovebox chamber that accommodates a cryocooler part excluding the cylinder. The cryocooler part includes a displacer of the cryocooler dismounted from the cylinder. The container is disposed in the first glovebox chamber and configured to accommodate the cryocooler part. The lid is disposed in the first glovebox chamber. The lid is configured to disconnect a cylinder chamber of the cylinder from the first glovebox chamber when the cooling subject is joined to the glovebox.Type: ApplicationFiled: October 21, 2021Publication date: May 26, 2022Applicant: Ulvac Cryogenics IncorporatedInventors: Masamichi Saitoh, Noboru OKUYAMA, Yukihiro SHIBATA, Junpei Yuyama

Patent number: 10571127Abstract: The gas turbine combustor includes a swirler lip on the air hole plate periphery, protruding toward a chamber, and a spring seal in an area for fitting the liner and the plate/lip. The spring seal has an air hole for passage of part of the combustion air introduced in the gap between the outer periphery of the air hole plate and the liner. The swirler lip has an air hole which introduces part of the combustion air passing through the spring seal air hole into the chamber. The liner has an air hole facing the spring seal air hole, to introduce part of air from outside the liner into the gap between the outer periphery of the air hole plate and the liner. A turn guide for rectifying a combustion air flow is provided at the liner end portion on the side for fitting the liner and air hole plate.Type: GrantFiled: October 23, 2017Date of Patent: February 25, 2020Assignee: Mitsubishi Hitachi Power Sytems, Ltd.Inventors: Keisuke Miura, Yasuhiro Akiyama, Tomohiro Asai, Kazuki Abe, Mitsuhiro Karishuku, Satoshi Dodo, Akinori Hayashi, Yoshitaka Hirata, Noboru Okuyama

Patent number: 10105836Abstract: A processing apparatus with a novel structure where a tool side rotates in relation to a main body side, capable of producing excellent quality transmission of an electrical signal from the tool side to the main body side with a simpler and more compact composition, and capable of driving an ultrasonic transducer provided on the tool side more effectively. A pair of signal coils are disposed between the main body side and the tool side so as to be able to transmit an electrical signal, and a power supply frequency to the ultrasonic transducer provided to the tool side is controlled by a power supply control member. At least one of the signal coils is provided with a coil winding path that reduces noise electromotive force generated due to an effect from power coils provided to the main body side and the tool side.Type: GrantFiled: January 16, 2013Date of Patent: October 23, 2018Assignees: MIE ELECTRONICS CO., LTD., TONGTAI MACHINE & TOOL CO., LTD.Inventors: Shuhei Takazakura, Toshikazu Mukai, Noboru Okuyama, Jui-Hsiung Yen, Hsin-Pao Chen
