摘要： When a demodulated signal of a radio signal in Ch1 transmitted from a TPMS transmitter is acquired, a control IC controls the frequency of a signal inputted from a PLL circuit to a mixer into a frequency for converting a TPMS radio signal into an intermediate frequency signal of a specific frequency. When the demodulated signal of the radio signal transmitted from a portable unit through two frequency channels is acquired, the control IC determines a channel whose state of communication is favorable from between Ch2 and Ch3, and controls the signal frequency for conversion into a frequency for converting a keyless radio signal in the determined channel into an intermediate frequency signal.

The outer element and the inner element of the antenna apparatus respectively serve as one of a signal line and a GND line, and are supported by a retainer member to have predetermined relationship on a land formation surface. The retainer member is made of dielectric body, and the two elements respectively have a surface mount portion at one end that is to be fixed onto the substrate with electrical connection to corresponding lands. The surface mount portions are formed substantially parallel to the land formation surface.

摘要： A smart portable device transmits a keyless radio signal for a keyless entry system by two frequency channels. In an integrated tuner, a control IC determines a frequency channel having a better communication state, and controls a frequency of a signal that is input to a mixer from a PLL circuit to a frequency for converting the keyless radio signal of the determined frequency channel into an intermediate frequency signal. This configuration makes it possible to share a circuit for receiving the keyless radio signals of those two frequency channels, and to receive the keyless radio signal of the frequency channel having the better communication state to surely conduct communication.

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： 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.
