| 20120104415 | SEMICONDUCTOR DEVICE - A semiconductor device includes: an emitter electrode formed of a silicide film, and provided on a semiconductor layer; an insulating film provided on the emitter electrode; and an electrode pad made of Al, and provided on the insulating film. | 05-03-2012 |
| 20110132019 | HEAT PUMP APPARATUS - A heat pump apparatus includes a refrigerant circuit in which a compressor, a condenser, expansion means, and an evaporator are serially connected. Condensation temperature detection means that detects a saturation temperature of the condenser, and evaporation temperature detection means that detects the saturation temperature of the evaporator are provided. Operation efficiency is estimated by a value obtained by dividing heating ability estimated from a detection value of the condensation temperature detection means by a difference between a detection value of condensation temperature detection means and that of evaporation temperature detection means or dissipation power estimated by the difference. | 06-09-2011 |
| 20110078218 | EVENT HISTORY STORAGE DEVICE, EVENT HISTORY TRACKING DEVICE, EVENT HISTORY STORAGE METHOD, EVENT HISTORY STORAGE PROGRAM, AND DATA STRUCTURE - When an instance targeted for tracking is divided or replicated to generate a new instance, ready and continuous tracking of a history of an event related to the original instance and the new instance is allowed. A behavior ID is assigned to an event for each instance, and an occurrence order of the event is managed for each instance. When a new instance has been generated from an instance due to a certain event, a new behavior ID is assigned to the new instance, with respect to that event. Then, the new identifier and an identifier assigned to the instance that is a generation source for the event are associated. | 03-31-2011 |
| 20100102146 | FUEL INJECTION VALVE - A fuel injection valve includes a valve main body of a hollow tubular shape, a needle valve provided to the valve main body in a slidable manner, a valve seat opposing the needle valve to form a seat portion and having an injection hole formed downstream of the seat portion, and a guide portion provided upstream of the seat portion to guide the needle valve. An annular passage communicating in a circumferential direction is defined between the inner peripheral surface of the valve main body and the outer peripheral surface of the guide portion and a fuel passage through which to introduce a fuel from the annular passage to the seat portion is defined. An almost cylindrical filter to trap foreign matter heading toward the fuel passage is provided to the annular passage. | 04-29-2010 |
| 20100010711 | VEHICLE CONTROL DEVICE - In the conventional vehicle control device, since a detection timing of turn is late, at the time of making the change of gear ratio based the detection timing, a sense of discomfort is brought to a driver. Moreover, steering wheel angle sensor, yaw rate sensor or lateral acceleration sensor is very expensive, resulting in the cost increase of the vehicle control devices. From information regarding a steering force that can be obtained from an electric power steering device, a turn intention of a driver is detected, and based the turning intention, the change of gear ratio is conducted. | 01-14-2010 |
| 20090265076 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - To improve accuracy of learning of a full-close reference position of a throttle valve while suppressing deterioration in startability and mechanical durability and power consumption, an ECU performs position learning processing and learning permission judgment processing as a part of opening and closing control for the throttle valve. In the learning permission judgment processing, the ECU judges whether all of a first learning permission condition, a second learning permission condition, and a third learning permission condition are satisfied. The third learning permission condition is a condition judged by the ECU as being satisfied when intake passage pressure MP exceeds a predetermined value kMP registered in the ECU in advance. The predetermined value kMP is a value for excluding an error due to negative pressure from throttle opening TP detected by a throttle opening sensor. | 10-22-2009 |
