20130006452 | TRAIN SPEED CONTROL APPARATUS AND TRAIN SPEED CONTROL METHOD - To stop a train at a desired target stop position without outputting excessive brake by outputting an appropriate braking instruction in accordance with a running condition of the train. An on-train computing device causes an acceleration estimating unit to determine the presence/absence of a current acceleration of a train and to estimate the current acceleration based on train-car information obtained from a train-car performance manager unit, and causes a profile calculating unit to generate a braking instruction profile based on a presumption that the train is running at the current acceleration when the train is in an accelerating condition, and to generate the braking instruction profile based on a presumption that there is no acceleration applied to a train car of the train by a propulsion control of the train car itself when the train is in a coasting condition. | 01-03-2013 |
20120202547 | CHANNEL ALLOCATION NOTIFYING METHOD, COMMUNICATION METHOD, AND COMMUNICATION APPARATUS - The number of communication channels necessary for communication with a terminal is calculated by using type and volume of data to be transmitted. When calculated number of communication channels is one, a single communication channel is allocated based on quality information of a communication line to the terminal and, when calculated number of communication channels is more than one, then more than one communication channels are allocated based on the quality information. Allocation information used for notifying of allocated communication channels is generated based on virtual channels, which are defined in advance as channel units having a combination of a plurality of consecutive communication channels, and the allocation information is transmitted to the terminal. | 08-09-2012 |
20120176405 | IMAGE CONSTRUCTION APPARATUS AND COMPUTER-READABLE MEDIA - An image construction apparatus has functions of, based on an instruction from a user, creating a binary-coded program, creating a database, and associating the database with an image part. The use of those functions allows the user to easily construct an image including an image part associated with both the program and the database. Some embodiments enable easy association of information on an apparatus to be operated with image parts constructing an image displayed by a remote control apparatus. Some embodiments are suitable for constructing the screen of the remote control apparatus having a graphical user interface. | 07-12-2012 |
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 |
