Patent number: 8284224Abstract: A thermal printer allows ink ribbon replacement without interference of a hook positioned in the opened state particularly in an ink ribbon replacement operation. A thermal printer includes a head lock lever 40 which includes a hook 41 at the tip of the lever. The hook is mounted such that it can be moved in the longitudinal direction relative to a turn shaft 26 during turning of the turn shaft 26, allowing the distance between the turn shaft 26 and the hook 41 to be changed. A movement control moves the head lock lever 40 such that the distance between the turn shaft 26 and the hook 41 in the opened state in which the thermal head 12 is separated from the platen roller 11 is smaller than that in the pressed state in which the thermal head 12 is pressed into contact with the platen roller 11.Type: GrantFiled: October 6, 2008Date of Patent: October 9, 2012Assignees: Kabushiki Kaisha Sato, Kabushiki Kaisha Sato Chishiki Zaisan KenkyusyoInventor: Yasuhide Takeda

Publication number: 20120037833Abstract: A powder valve is propose which is simple in structure and small in size, which can prevent powder from getting stuck in the valve, and can withstand high feed pressure. The valve includes a valve casing 21, a valve shaft 25, and a valve body 22 mounted in the valve casing 21 and supported by the valve shaft 25. The valve body 22 has a spherical outer surface 27 configured to be brought into contact with a valve seat 23 of the valve casing 21 to close the valve. The valve body 22 is formed with a communication hole 26 extending in a direction perpendicular to the valve shaft 25 so that when the valve body 22 is rotated about the valve shaft 25 in either of two opposite directions from the closed position, the valve is configured to open through the communication hole 26. The communication hole 26 is open on the back side of the valve body 22 over the entire length thereof. With this arrangement, it is possible to ensure the advantages of a ball valve, i.e. full-bore properties and high rigidity.Type: ApplicationFiled: March 26, 2009Publication date: February 16, 2012Inventors: Takayuki Miyazaki, Yasuhide Takeda, Shigeo Fukui, Shinji Takahashi, Takashi Arai

Patent number: 6815629Abstract: In a hydraulic pressure actuating apparatus for a circuit breaker, contacts of the circuit breaker have a moving contact and a stationary contact for turning on/off current. A shaft, at an end portion of which is attached the moving contact, and at the other end of which is attached a piston, is received within a cylinder. A directional control valve exchanges oil pressure for actuating the piston. For changing over the directional control valve, pilot valves are provided. Each pilot valve has a pair of valve bodies, each opposing to each other, and springs. One of the valve bodies is able to stroke up to contact with the valve body of the other valve body, therefore giving no ill influences upon actuating time, even if drawback occurs in the pilot valves in the hydraulic pressure actuating apparatus for the circuit breaker.Type: GrantFiled: May 16, 2003Date of Patent: November 9, 2004Assignee: Hitachi, Ltd.Inventors: Shinji Seto, Yasuhide Takeda, Daisuke Ebisawa, Masayuki Uchiyama, Atsuji Watanabe, Hideo Kawamoto
