Patent number: 10087870Abstract: A fuel injection controller is applied to a fuel injector injecting fuel to be combusted in an internal combustion engine by an open-valve operation of the valve body according to an electromagnetic suction force generated by an energization of a coil. The fuel injection controller controls an injection state of the fuel injector by controlling a coil current flowing through the coil. The fuel injection controller includes an increasing control portion which increases the coil current to a first target value, a holding control portion which holds the coil current increased by the increasing control portion to the first target value, and a changing portion which changes the first target value according to the operation state of the internal combustion engine.Type: GrantFiled: November 4, 2013Date of Patent: October 2, 2018Assignee: DENSO CORPORATIONInventors: Keita Imai, Eiji Ito

Patent number: 9970435Abstract: A high-pressure pump has an elastic member arranged in a damper chamber between a first diaphragm and a second diaphragm. The elastic member is always in contact with both diaphragms while the high-pressure pump is operated. When the diaphragms are further vibrated due to a resonance under a situation where a frequency of the pressure pulsation of low-pressure fuel is in agreement with the characteristic frequency of the diaphragms, the elastic member restricts the deformation of the diaphragms. Therefore, the resonance of the first diaphragm and the second diaphragm can be restricted.Type: GrantFiled: June 3, 2015Date of Patent: May 15, 2018Assignee: DENSO CORPORATIONInventors: Masayuki Kobayashi, Eiji Ito, Yoshitomo Oguma, Yuusuke Andou

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
