Abstract: A resolver for detecting the displacement amount of a passive body is provided with an excitation winding or a detection winding. The detection is based on a detection signal outputted from the detection winding as a result of an excitation signal inputted to the excitation winding. The excitation winding and/or the detection winding are composed of a combination of one or more sheet coils having one or more bore portions. The sheet coils are arranged at prescribed intervals in the lengthwise direction of a magnetic core to which the sheet coils are attached. A plurality of coil-storing grooves formed in a direction perpendicular to the lengthwise direction are provided in the core surface of the magnetic core. The coil portions of at least two portions of the respective sheet coils are accommodated in the coil-storing grooves.

Abstract: A motor driving device is provided. The motor driving device includes a driving unit configured to drive a starter motor/generator that is directly connected to an engine by a rotation shaft, by performing on/off control of switching elements in a bridge circuit for driving a motor; and a driving controller configured to control a driving operation for the starter motor/generator that is performed by the driving unit. The driving unit controls a motor driving voltage for the starter motor/generator by changing ON periods of the switching elements of the bridge circuit, and turns on predetermined switching elements of the bridge circuit at a predetermined timing to perform an active freewheel operation for boosting a regenerative voltage generated by the starter motor/generator. The driving controller instructs the driving unit to control the motor driving voltage and on/off of the active freewheel operation, based on a battery voltage.

Abstract: A touch panel includes a substrate having an operation face, a sensor part provided at a sensor face of the substrate, and a wire led out from the sensor part to the sensor face to be connected to an external connection part. The sensor part and the wire are covered by an insulation layer. A cutout is provided to the insulation layer to expose a part of the wire to which the external connection part is connected. An insulation part is provided to cover the external connection part, the insulation layer and the wire located at the cutout. The touch panel can reliably prevent static electricity generated at the operation face during panel operation from entering the sensor part via the wire and the external connection part and causing electrostatic destruction of a bridge and such of the sensor part.

Abstract: This communication system has a transmitter and a receiver for repeatedly transmitting a frame of steering signal having a plurality of channels. The transmitter stores an identification data of a control parameter of a specific operation object in a first empty channel within one frame and stores a characteristic data of the control parameter of the specific operation object in a second empty channel to transmit along with steering data of other channels. Since the identification data and the characteristic data are transmitted at the same time along with the control data, the control parameters can be changed during steering of the operation object. Since the characteristic data and the identification data are transmitted in the same frame as a pair, when at least the one frame is received, the setting of the control parameter can be changed.
