Patent number: 8833335Abstract: A control device has a mechanical oil pump driven by an engine and an electric oil pump supplying oil via a check valve in an oil passage connecting the mechanical oil pump and the electric oil pump, the check valve allowing a flow of the oil from the electric oil pump side to the mechanical oil pump side while blocking a flow in an opposite direction, regardless of the pressure of the electric oil pump. When the check valve is closed under an oil pressure condition in which the electric oil pump outputs a maximum output oil pressure while the mechanical oil pump is driven by the engine at idle, the control device is configured to drive the electric oil pump during stop of the mechanical oil pump, and to stop the electric oil pump based on a load increase after start of the mechanical oil pump.Type: GrantFiled: February 15, 2011Date of Patent: September 16, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventor: Masahiro Karasawa

Patent number: 8801126Abstract: A liquid chamber receives liquid flows from a liquid receiving unit. A first urging member urges a deforming portion of the liquid chamber. A lever provided on the liquid container side increases the displacement of the deforming portion. A sensor detects the displacement. A transmitting member transmits the increased displacement to the sensor. A second urging member provided on a liquid consuming apparatus side urges the transmitting member. When the liquid container is installed in the liquid consuming apparatus, the transmitting member comes in contact with the lever member due to the urging force of the second urging member, and the lever member is pushed against the deforming portion. In this manner, it is possible to divide the liquid detection system into the liquid consuming apparatus side and the liquid container side.Type: GrantFiled: December 19, 2011Date of Patent: August 12, 2014Assignee: Seiko Epson CorporationInventors: Masahiro Karasawa, Yuji Aoki, Masaru Takahashi

Patent number: 8746862Abstract: Part of a liquid chamber communicating with a liquid storage is formed of a deformable portion which is deformed. Part of a lever is brought into abutment with the deformable portion and, when the deformable portion is deformed, the lever is rotated about a supporting portion. The liquid storage, the liquid chamber, and the lever are stored in the interior of the case having a through hole, and when the liquid container is mounted on the liquid consuming apparatus, the movable rod on the side of the liquid consuming apparatus is inserted from the through hole and is brought into abutment with the lever.Type: GrantFiled: June 13, 2012Date of Patent: June 10, 2014Assignee: Seiko Epson CorporationInventors: Masahiro Karasawa, Yuji Aoki, Masaru Takahashi

Patent number: 8668301Abstract: A cavity is provided between a supply port which supplies the liquid which is received in the liquid reception unit to the outside and the liquid reception unit, with a variable portion which is deformed between the supply port and the liquid reception unit. The variable portion is urged using an urging member from the inside of the cavity through a pressure reception member. In addition, a change in a position of the pressure reception member can be detected using a detection unit. Further, a notch is provided at a surface where the pressure reception member comes into close contact with the urging member, in which the notch extends to the outside from the inside of the contact surface.Type: GrantFiled: December 6, 2011Date of Patent: March 11, 2014Assignee: Seiko Epson CorporationInventors: Masahiro Karasawa, Yuji Aoki
