摘要： Safety against error setting of a primary battery in a dedicated battery charger for secondary batteries can be assured even when the battery charger is of a timer type advantageous for cost reduction. A switching circuit (2) is connected between terminals (13, 15), and terminals (14, 16) are connected. Terminals (15, 17) are connected, and terminals (16, 18) are connected. The positive pole of a battery (3) set in position is connected to the terminal (17), and the negative pole is connected to the terminal (18). A battery discriminating circuit (4) connects to the positive pole and the negative pole of the battery (3) set in position; and judges whether the battery (3) is a primary battery or a secondary battery. Depending upon the result of the discrimination, the battery discriminating circuit (4) supplies a switching signal to the switching circuit (5) to turn it on or off. A capacitor (6) and a resistor 7 are connected in parallel between a timer circuit (9) and a ground potential. The switching circuit (5) and a resistor (8) are connected in series between the timer circuit (9) and the ground potential. Once the switching circuit (2) turns on, a constant voltage source circuit 1 supplies a charging direct current to the secondary battery.

摘要： A retransmission control apparatus for use in a radio communication system that uses an orthogonal frequency division multiplexing technique, the apparatus comprising a transmitter which transmits to a radio station a data sequence, which serves as communication data that has been transformed into a time waveform of an orthogonal frequency division multiplexing symbol; a receiver which receives from the radio station a retransmission request for retransmitting the communication data; a transformation mechanism configured to transform, in response to the retransmission request, the data sequence of the communication data to be retransmitted into an orthogonal frequency division multiplexing symbol having a time waveform different from the time waveform of the orthogonal division multiplexing symbol which had been sent before the retransmission request; and a retransmitting mechanism configured to retransmit the communication data transformed by the transformation mechanism to the radio station. Since the time waveform of the resulting OFDM data symbol after the retransmitting operation is changed from that before the retransmitting operation, it is highly likely that the average power of the transmitting signal is increased. As a result, the occurrence of errors when the data sequence is retransmitted is reduced, thereby improving the throughput.
