Title: Frequency division multiplex signal generator and decoder
Inventor: TAKAHASHI NOBUAKI
IPC: H04J11/00
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To obtain the frequency division multiplex signal generator by which miniaturization and light weight of a transmitter are attained by generating a frequency division multiplex signal of plural groups and controlling the polarity of the frequency division multiplex signal so as to reduce a peak power. SOLUTION: An inverse high speed Fourier transformation (IFFT) circuit 33 divides input real number part data and input imaginary number part data respectively into plural numbers, and plural arithmetic sections conduct IFFT arithmetic operation. Plural peak detection circuits 37-40 detect a peak power and a peak position of the frequency division multiplex signal outputted from the circuit 33 for each group. When a peak power of a prescribed value or over is detected, polarity control circuits 42-45 set the polarity of the frequency division multiplex signal of other groups in a direction to cancel the peak power of a prescribed value or over to suppress instantaneous power. The IFFT circuit 34 applies IFFT arithmetic operation to a polarity control signal from the data polarity discrimination circuit 41.  An adder circuit 46 adds output signals of the circuits 33, 34 to provide an output of a signal whose peak power is suppressed to a prescribed value or below to an orthogonal modulator 47.

Title: Photovoltaic power generating device
Inventor: MORISHIMA YOICHI
IPC: G05F1/67
Filed: 1985-11-27
Abstract: PURPOSE:To prevent an excess voltage protecting device from malfunction by applying voltage to the 2nd resistor during the stop of an inverter of the voltage applied to the inverter exceeds a prescribed value. CONSTITUTION:When the inverter 7 is started from its stopped state, the output voltage of a solar battery 1 is reduced in accordance with the increase of current and the voltage Vin applied to the inverter is also reduced. Since the excess voltage protecting circuit is not driven after starting the inverter 7, the time (t) is measured by a timer in a relay contact control device 8, and after the passage of the time (t), a relay 6 is closed to impress the output voltage Vop of the solar battery to the inverter 7 as it is. If the inverter 7 is stopped by any cause, the output voltage is boosted in accordance with the decrease of the output current and reached to its opened voltage Vmax. Since the relay contact control device 8 has opened the relay 6 immediately after receiving an operation stop signal from the inverter 7, the input voltage Vin of the inverter 7 is divided by resistors 4, 5 and set up to a voltage value to be applied to the resistor 5.

Title: Antenna switching circuit
Inventor: OGIWARA MAMORU
IPC: H03K17/76
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of distortion by providing a third switching diode connected to the anode side of a second switching diode and a second coil between the cathode side of the third diode and the ground. SOLUTION: At the time of transmission, the output of an Rx bias circuit 6 is turned off and the output of a Tx boas circuit 5 is turned on. Thereby diodes CR2 and CR3 on a receiving side are turned off and a diode CR1 on a transmitting side if turned on. A high frequency transmission signal inputted from a Tx terminal 2 is regarded as resistance because CR1 is in an on state, and comes in to the state of being directly connected to a coil L2. At this time, as CR2 is not biased, CR2 operates as a diode and a capacitor C3 is biased by negative voltage. At this time, some of the currents charged to C3 are charged through C3, L3 and CR2 from the ground and the other currents are charged through L4, CR3 and CR2. The currents through CR3 do not flow due to a diode characteristic.
