  • Patent number: 8512202
    Abstract: A shift controller controls a transmission for a hybrid vehicle in which: an engine and a motor are connected together via a clutch; and the transmission is placed between the motor and driving wheels. The shift controller has: a first shift controlling unit which performs shift control on a basis of at least one of transmission efficiency of the transmission and power generation efficiency of the motor in a case where regeneration is performed with the clutch disengaged during deceleration of the hybrid vehicle; and a second shift controlling unit which performs shift control to make a transmission gear ratio of the transmission smaller than in the shift control performed by the first shift controlling unit in a case where the regeneration is performed with the clutch engaged during the deceleration of the hybrid vehicle.

  • Patent number: 7897306
    Abstract: An embodiment of the present invention will be disclosed below. A bank substrate comprising: a substrate and a bank on the substrate, wherein a surface energy of the bank is 30 to 45 mJ/m2. Further, colored pixels are present between zones of the bank, and the difference of height within a pixel of the colored pixels is 0.3 ?m or less. The colored pixels comprise colored inks, and a viscosity of the colored inks is 50 mPa·s or less.

  • Publication number: 20100085942
    Abstract: There is provided a base station having a resource assigning unit for assigning QoS resources in response to a QoS setting request and a resource securing unit for securing, when a wireless communication terminal that is communicating with a base station by setting a QoS specifies the own base station as a handoff candidate base station, QoS resources by correlating to the wireless communication terminal. The resource assigning unit assigns, in the case where there are no QoS resources available when assigning QoS resources in response to the QoS setting request, the QoS resources that have been secured by the resource securing unit by correlating to the wireless communication terminal to a wireless communication terminal that has transmitted the QoS setting request.

  • Publication number: 20090011888
    Abstract: An automatic transmission hydraulic pressure control apparatus decreases a hydraulic pressure lower limit value as much as possible without causing a non-operating zone of a solenoid valve to be included in a control region of the solenoid valve due to product variation. First and second determinations are alternately performed to determine if a solenoid command value is in a non-operating zone by alternately changing the solenoid command value to decrease and increase the actual hydraulic pressure in a step-like manner. The solenoid command value of an immediately previous cycle in which the first determining section determined that the solenoid command value was not in the non-operating zone is set as a solenoid command limit value when one of the first and second determining sections has determined that the solenoid command value is in the non-operating zone.

  • Patent number: 7359785
    Abstract: A starting device has a friction element arranged between an engine and wheels for transmitting torque between them. The engagement and disengagement of the element is shifted by press force outputted from a press force applier, which is controlled by a control unit. The control unit includes a creep demand degree judging means judging a driver's creep demand degree for starting a motor vehicle after substantial stop of the vehicle with applying brake force to the wheels and outputs a creep demand degree signal, a creep time setting means setting creep time based on the creep demand degree signal and outputs a creep time signal, and a creep torque producing means producing creep torque by controlling the press force to obtain a slipping state of the element for a period determined based on the creep time signal.
