Patent number: 9957851Abstract: Provided are a variable valve timing mechanism, an oil pump supplying oil to a hydraulically-actuated device including the variable valve timing mechanism, and a hydraulic control valve which controls oil pressures supplied to a locking mechanism (which includes a locking member configured to fix a phase angle of a camshaft relative to a crankshaft) of the variable valve timing mechanism, an advanced angle chamber and a retarded angle chamber. While an oil pressure in a hydraulic path detected by a hydraulic sensor increases, a hydraulic control valve controller adjusts a degree of opening of a hydraulic control valve according to the detected oil pressure at a time of releasing the locking member from a locking state, to reduce the oil pressure to be supplied to the advanced angle chamber or the retarded angle chamber used to change the phase angle of the camshaft relative to the crankshaft.Type: GrantFiled: February 23, 2015Date of Patent: May 1, 2018Assignee: MAZDA MOTOR CORPORATIONInventors: Tatsuya Takahata, Keiichi Miyamoto

Patent number: 9500107Abstract: A control system for an engine is provided. The system includes a hydraulically-operated variable valve timing mechanism, a variable oil pump, and a hydraulic-pressure control valve. The variable valve timing mechanism has advance-side and retard-side operation chambers and a locking mechanism. The system includes a hydraulic-pressure sensor for detecting hydraulic pressure within a hydraulic-pressure path, and a pump control device for performing a target hydraulic-pressure control. During a change of an engine operating state in a specific operation of the engine, while an unlocking operation of a locking member of the locking mechanism is performed, the pump control device performs, instead of the target hydraulic-pressure control, a discharge amount restricting control to control the hydraulic pressure to be an upper-limit hydraulic-pressure value or lower, which is an upper limit to perform the unlocking operation.Type: GrantFiled: March 3, 2015Date of Patent: November 22, 2016Assignee: Mazda Motor CorporationInventors: Tatsuya Takahata, Keiichi Miyamoto

Patent number: 9065938Abstract: An apparatus, system, method, and a non-transitory recording medium storing an image inspection control program, each of which is capable of inspecting a printed image based on comparison between a read image read from the printed image and an inspection image. As a portion of the read image is obtained, the size of the obtained portion of the read image is corrected to match the size of the inspection image, using a magnification ratio previously obtained. After matching the sizes of the read image and the inspection image, the read image is compared with the inspection image to inspect the read image.Type: GrantFiled: March 8, 2013Date of Patent: June 23, 2015Assignee: RICOH COMPANY, LTD.Inventors: Tadashi Kitai, Hitomi Kaneko, Hiroyoshi Ishizaki, Keiji Kojima, Hiroyuki Kawamoto, Keiichi Miyamoto

Patent number: 8991347Abstract: A starting device of a spark-ignition multi-cylinder engine is provided. The device includes a multi-cylinder engine body having cylinders, fuel injection valves, ignition plugs, an intake valve drive mechanism for opening and closing intake valves, a hydraulic variable valve phase mechanism for changing a close timing of each intake valve, an engine-driven hydraulic pressure supply source for supplying a hydraulic pressure, and a start controller for controlling the fuel injection valves, the ignition plugs, and the variable valve phase mechanism. When the supplied hydraulic pressure is below a predetermined pressure, the variable valve phase mechanism locks the close timing. When an engine temperature in an engine-start is high, the start controller retards a fuel injection timing of the cylinder on intake stroke at an engine stopped timing and retards an ignition timing thereof. The start controller does not retard the close timing of the intake valve until the engine-start completes.Type: GrantFiled: January 13, 2014Date of Patent: March 31, 2015Assignee: Mazda Motor CorporationInventors: Keiichi Miyamoto, Kouji Shishime, Yoshitaka Wada, Tatsuya Takahata
