Abstract: A power control apparatus includes a busbar unit which supports a plurality of busbars connected to a plurality of semiconductor modules. The busbar includes a first plate shaped portion and a second plate shaped portion. The first plate shaped portion is adjacent to a cooling device in a posture facing an internal passage of the cooling device in the plate thickness direction. The second plate shaped portion is placed in a posture in which a plate thickness direction thereof intersects with a plate thickness direction of the first plate shaped portion. The second plate shaped portion has outer surfaces including a side surface having a narrower width corresponding to a plate thickness. The second plate shaped portion is placed in a posture in which the side surface faces the semiconductor module.

Abstract: A power amplifier module includes a first amplifier, a power splitter, a second amplifier, a third amplifier, a phase shifter, a combining unit, and a controller. The first amplifier amplifies a first signal and outputs a second signal. The power splitter splits the second signal into a third signal and a fourth signal. The second amplifier amplifies the third signal and outputs a fifth signal. The third amplifier amplifies the fourth signal and outputs a sixth signal. The phase shifter receives the fifth signal and shifts a phase of the fifth signal. The combining unit combines the fifth signal having the phase shifted by the phase shifter and the sixth signal and outputs an amplified signal of the second signal. The controller outputs a first control signal for controlling a power level of the sixth signal output from the third amplifier.

Abstract: Provided is a position information providing system which can reduce a time required for acquiring position information. An indoor transmitter is adapted to provide position information by using a second positioning signal compatible with a first positioning signal which is a spread spectrum signal from each of a plurality of satellites. The indoor transmitter includes an EEPROM which stores therein position data for identifying an installation location thereof, an FPGA operable to generate a second positioning signal including the position data as a spread spectrum signal, and a transmitting section operable to transmit the spread spectrum signal. The second positioning signal is generated to repeat the same content in a cycle shorter than that of the first positioning signal.

Abstract: An indoor transmitter is capable of programmably changing a format of a transmitter signal. A process to be performed by a position information providing apparatus comprises the step of acquiring a received positioning signal, and the step of identifying an emission source of the positioning signal, wherein, if the emission source of the positioning signal is an outdoor source, the process further comprises the step of acquiring a navigation message included in the positioning signal, and the step of performing a processing for calculating a position based on the signal, or, if the emission source of the positioning sign is an indoor source, the process further comprises the step of acquiring message data from the positioning signal, the step of acquiring coordinate values from the data, and the step of displaying position information based on the coordinate values.

Abstract: Positional information is provided at a place out of reach of radio wave.

Abstract: A microcomputer 12 selectively generates signals corresponding to a cancel sound and a pseudo-engine sound respectively based on a rotation number of an engine and causes a switch 23 of a subsequence attenuator ATT 16 to be in an ON condition for attenuating the signal corresponding to the cancel sound if it is generated and causes the switch 23 to be in an OFF condition for passing the signal corresponding to the pseudo-engine sound through it if it is generated.

Abstract: The invention provides an electric motor in which a cost is reduced by reducing a number of the parts, and an electric motor in which a freedom of placement is increased. A motor assembly has a yoke and a front bracket closing an open end of the yoke. The front bracket is formed in a closed-end cylindrical shape by an aluminum die casting, and a brush holder for holding a brush is received in an inner portion. A motor controller for controlling the motor assembly is formed as an electronic circuit having a communication portion, a control portion and a driver portion, and this electronic circuit is mounted on an inner peripheral surface of the front bracket. Further, the electronic circuit constituting the motor controller may be mounted on the brush holder.
