摘要： An antenna includes outer and inner elements, one of which is a signal line and the other of which is a ground line. Each of the outer and inner elements is a helical element having helical portions. The inner element is arranged inside the outer element such that the outer and inner elements are spaced from each other. An axis of the outer element is parallel to that of the inner element.

摘要： Two standard waves from a standard waveform generation circuit are output via an output gate while being interchanged by a direction selector. The switching operation of the direction selector is controlled by a direction control signal M/I. 200 cycles of the standard waveforms are counted by a 200-cycle counter. A drive counter is downcounted every 200 cycles, while the drive counter is upcounted in accordance with the number of drive pulses DRIVE. When the count value of the drive counter becomes zero, output from the output gate is thereby stopped.

摘要： A receiver to be used in a smart entry system for a vehicle is provided with an antenna device for receiving a transmission radio wave from a portable device, a receiver circuit for demodulating a receiving signal inputted from the antenna device to extract receiving data, and an AV wire mounted in a rear bumper of the vehicle. The antenna device is constructed with a built-in antenna built in the receiver for receiving a radio wave, an impedance matching circuit for performing impedance matching with the built-in antenna, and a Wilkinson combining circuit which receives input of a first receiving signal received by the built-in antenna and a second receiving signal received by the AV wire to output a signal produced by combining the inputs of the first receiving signal and second receiving signal.

摘要： In the invention, pairs of output transistors are provided. An actuator having an inductance is connected to nodes formed between the pairs of output transistors. A drive circuit for the actuator is arranged such that the actuator is driven by causing a drive current to flow into the inductance. The drive circuit has an overvoltage detection circuit for detecting whether or not a voltage appearing at the nodes of the output transistor pairs exceeds a supply voltage by a first predetermined level and whether or not the voltage becomes lower than a ground level by a second predetermined level. Output transistors connected to the nodes are activated by an output from the overvoltage detection circuit.
