摘要： An Amplitude Shift Keying (ASK) modulating circuit includes an oscillation circuit generating a pulse oscillation having a given frequency. A frequency divider is provided having a binary counter unit and having at least an input terminal, an output terminal and a reset terminal. The frequency divider is active and inactive when the reset terminal thereof is applied with low and high levels of a transmission signal wave, respectively, and divides the pulse oscillation while the frequency divider is active. The transmission signal wave is modulated together with a carrier frequency which is identical to the divided frequency.

摘要： A transmitter portion 14 includes a control circuit 32, a driver circuit 33, and a wave detector circuit 35. The control circuit 32 generates control signals Vp, Vn based on a pulsed transmission signal So. The driver circuit 33, which is supplied with a battery voltage Vb, generates an output signal Sa to be sent to an antenna 13 based on the control signals Vp, Vn. The wave detector circuit 35 outputs a detection signal Sk having a voltage proportional to the level of the output signal Sa (transmission power level). The control circuit 32 changes the pulse widths of the control signals Vp, Vn based on the voltage level of the detection signal Sk. As a result, electric power consumption is reduced and enlargement of an apparatus is suppressed while maintaining the transmission power level constant.

摘要： A door approach transmission apparatus comprises an outside door handle 20 having a conductor with a slit 23 disposed in the door handle surface. A slot antenna 21, 23, 24, 25 is disposed at the slit 23, and includes feeding points 24, 25 installed on the conductor. The apparatus also includes a transmitter 26 for applying voltage for radio wave oscillation to the feeding points 24, 25. The above-described door approach transmission and reception apparatus can be used in a door lock control apparatus where a search radio wave is emitted from a vehicle, a portable wireless device 10 receives the search radio wave, and returns an ID signal. An electrically driven door lock apparatus 40 is driven to unlock the door when the returned ID signal coincides with a registered ID signal. The search radio wave is irradiated from the slot antenna. Either of a transmitter 26 and a receiver 33 is selectively connected to the feeding points 24, 25. By virtue of the above-described features, the emission and reception of radio waves is realized, and in the case of a door handle made of a metal, the number of parts for emission and reception of the radio waves are reduced.
