Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a multi-carrier communication equipment that can reduce deterioration in a transmission characteristic due to transmission waveform distortion caused by a transient response of a filter even in the case of adopting the filter with high leading/trailing transient response fluctuation. SOLUTION: An IFFT section 101 applies inverse discrete Fourier transformation to a transmission signal, a guard period addition processing section 102 adds a signal denoting a time width corresponding to a transient response time of an LPF 105 to a head and an end of a multi-carrier signal of one burst obtained by the inverse discrete Fourier transformation and provides an output of the result to a ramp processing section 103. The ramp processing section 103 applies waveform shaping to reduce spurious radiation to an out-band to its output signal of the ramp processing section 103, a digital/analog converter section 104 converts the output digital signal of the ramp processing section 103 into an analog signal and the LPF 105 suppresses an excess out-band signal component from the analog signal.

Filed: 1990-11-30
Abstract: PURPOSE:To prevent blackening of zirconia by providing a control voltage fluctuating means which detects voltage, applied to a pump cell, to change a predetermined control voltage value of an electromotive force cell in the case that an absolute value of the voltage exceeds the predetermined voltage. CONSTITUTION:The fourth and fifth amplifiers A4, A5 detect pump voltage Vp, applied to a pump cell 3, to constitute a control voltage fluctuating means for changing a predetermined voltage value of an electromotive force cell 5 in the case that an absolute value of the voltage Vp exceeds the predetermined voltage. Outputs of the amplifiers A4, A5 are connected to a connection point 32 via a resistor R18 respectively through diodes D1, D2. When an absolute value of the voltage Vp, applied to the pump cell 3, is the predetermined voltage or less, the voltage is impeded by the diodes D1, D2 to generate no current to flow in the resistor R18, and when the value is increased to the predetermined voltage or more, a current is allowed to flow into the connection point 32 via the diode D1 from the amplifier A4 to increase voltage of the connection point 32. On the other hand, when the voltage is decreased to the predetermined voltage or less, a current is allowed to flow into the amplifier A5 via the diode D2 from the connection point 32 to drop the voltage of the connection point 32.

Abstract: PURPOSE:To equalize specifications of a dimmer, and set it applicable to a capacity of a lighting load by providing a time sharing change control part to actuate the dimmers cyclicly in order for every half cycle of an AC power supplied to the lighting load. CONSTITUTION:On-zones of a photo-MOS 41 of a time sharing change control part 4 are changed in such a way that triacs 11 provided at three dimmers A-C are time-sharingly ignited for every half cycle of voltage waveforms of an AC power supply 3 applied to a lighting load 2.

Ignition action is therefore performed for 1/3 duty compared to a case of a single dimmer for one triac 11. As a result, the dimmer can be formed as modules of the same specifications, and by adjusting the number of the dimmers combined with each other, to cope with a load from a small capacity to a large capacity.

Abstract: PURPOSE:To compensate atmospheric pressure by compensating suction pressure according to the rotational speed of an engine when a throttle valve is at a fully open position or near the fully open position, and taking the pressure after compensation as atmospheric pressure to restrain the rise in cost. CONSTITUTION:An electronic controller 2 takes in the rotational speed of an engine only when a power increment switch SW5 is ON, by which pressure compensation value PN is determined.

The suction pressure P detected by a pressure sensor 4 is taken in, and the value where the pressure compensation value PN is added to it is set at a prescribed address as atmospheric pressure PO. When the throttle valve 8 is operated up to the proximity to a fully open position, atmospheric pressure is detected according to the then suction pressure, and a fuel injection quantity is adjusted according to the atmospheric pressure.

Title: Discharge lamp lighting device
Inventor: TOYAMA KOICHI
IPC: H05B41/288
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To enable lamp applying power to be maintained to a required level even if the leakage current during capacitor full charging increases in a power calculation circuit. SOLUTION: Lamp applying power is controlled based on a terminal voltage Vc of a capacitor 111 to be determined by means of a time constant circuit 112 during warm-up control. Therefore, if the leakage current of the capacitor 111 during capacitor full charging increases, the terminal voltage Vc decreases by ΔV, and the lamp applying power becomes a value deviated from the required level. However, the lamp applying power is controlled based on the voltage of a specified value (as during warm-up control, the result is the terminal voltage Vc of the capacitor 111, however, the parallel circuit between resistors 117 and 113 of their low resistance values are generated due to the conductivity of a transistor 118 and the value is almost equal to a constant voltage Vcc.), therefore, the lamp applying power can be maintained to the required level.
