Patent number: 8726096Abstract: A controller and a control method for a controller can simplify application development and can improve the performance of device control processes. When a request is received from an application 1 and the received process request is an initialization request, whether or not the received request is the first initialization request received after the application 1 started running is determined. If the received initialization request is the first initialization request, the request is passed to the device driver 3 and initialization settings information describing the configuration of the device driver 3 after the initialization process ends is stored. If an error has occurred in the device driver 3 when the device driver 3 status is detected, an error handling process is executed according to the device driver 3 state. When the device driver 3 has recovered, a request for setting the device driver 3 state to the state based on the initialization settings information is asserted.Type: GrantFiled: May 6, 2013Date of Patent: May 13, 2014Assignee: Seiko Epson CorporationInventors: Nobuhiro Nishimura, Toshihiro Hagiwara, Eiji Ito, Atsushi Sakai

Publication number: 20070251380Abstract: A part of a rubber layer of the base section of a piston seal is replaced with a reinforcement ring with high rigidity, and a part of the reinforcement ring reaches the root of a seal lip. This provides the piston seal with required rigidity. Further, providing an outer diameter side radial section on a piston body secures a contact width coming into contact with a section to be pressed. A piston has a piston body (111) having a clutch pressing section (111f) provided so as to be in surface-contact with a multiple disc clutch (105), a reinforcement ring (112) fitted on the outer periphery of an outer cylinder section (111e) of the piston body, and an outer peripheral seal lip (113a) provided on the reinforcement ring and in sealing contact with the inner peripheral surface (102a) of the outer peripheral section of a housing (102).Type: ApplicationFiled: March 18, 2005Publication date: November 1, 2007Applicant: NOK CORPORATIONInventors: Yoshiyuki Kanzaki, Nobuhiro Nishimura
