20110284441 | VORTEX FLOW TYPE WATER SURFACE CONTROL DEVICE FOR DRAINING DEVICE - A vortex flow type water surface control device for a draining device is provided. The vortex flow type water surface control device may include an inflow pipe, an outflow pipe, an intercepting pipe, and a separating weir that is disposed to block the intercepting pipe and the inflow pipe from the outflow pipe. The vortex flow type water surface control device may also include a control plate that is disposed between an opening of the inflow pipe and an opening of the intercepting pipe. A height of the control plate may be higher than at least a height of the separating weir. The control plate may be apart from the separating weir, and may approximately extend to a center axis of the intercepting pipe. | 11-24-2011 |

20100282558 | HYDRAULIC CONTROL DEVICE OF LOCKUP CLUTCH - A hydraulic control device for a lockup clutch prevents stagnation and accumulation of air bubbles in a torque converter when a vehicle is at a stop at low oil temperature, preventing impairment of vehicle drive performance caused by insufficient transmission torque at the time of start of the vehicle. It occurs sometimes that air-mixed hydraulic oil is supplied into a torque converter from a second oil path when a vehicle is at a stop, with a transmission set to a drive range such as a D range, at a low oil temperature in a time, for example, immediately after an engine is started. In such a case, when a lockup clutch is disengaged, in which a second line hydraulic pressure is supplied from the second oil path to the lockup clutch, a third oil path is interrupted (closed) to prohibit discharge of the hydraulic oil. As a result, despite large pipe path resistance due to low viscosity, the hydraulic oil in the torque converter is reliably discharged from a first oil path to an oil cooler via a cooler oil path. Thus, air bubbles in the torque converter are reduced with the discharge of the hydraulic oil. | 11-11-2010 |

20100095795 | Transmission - A transmission includes a case having an internal space; a first partition wall which is provided in the case and forms a boundary between a first chamber which is arranged in the case and houses a rotating object, and a second chamber which is arranged in the case, is connected to the first chamber, and maintains equal pressure between the first chamber and outside air; a second partition wall which is provided in the case and forms a boundary between the second chamber and a third chamber which is arranged in the case and stores fluid below the second chamber; and a third partition wall which is provided in the case and forms a boundary between the first chamber and the third chamber. A first hole and a second hole are formed in that order from the first chamber side in the second partition wall. | 04-22-2010 |

20090312927 | CONTROL APPARATUS AND CONTROL METHOD FOR VEHICLE MOUNTED WITH AUTOMATIC TRANSMISSION - An ECU executes a program including the steps of: determining whether or not the conditions for execution of low-temperature neutral control: the temperature of the automatic transmission hydraulic fluid is at most a threshold value; the shift position is D or R position; the vehicle speed is zero; and the brake is ON and the vehicle is stopped, are continuously satisfied for a period of time represented by a threshold value; executing the neutral control when the conditions for execution of low-temperature neutral control are continuously satisfied for at least the period represented by the threshold value; returning from the neutral control when the conditions for execution of low-temperature neutral control are not satisfied; and restricting the throttle opening position in returning from the neutral control. | 12-17-2009 |
