摘要： An air conditioner has a refrigeration cycle and a regulating circuit. The refrigeration cycle includes a compressor of variable exhaust amount type, a 4-way valve connected to the discharge side and suction side of the compressor, indoor-side and outdoor-side heat exchanges connected to the valve, and an expansion valve of a motor-driven tape. The regulating circuit regulates the flow rate of refrigerant into the indoor or outdoor side heat exchanger by adjusting the opening degree of the expansion valve in response to the amount of the refrigerant exhausted from the compressor, thereby setting the temperature of the refrigerant to be discharged from the compressor to a predetermined temperature responsive to the exhaust amount of the compressor.

The speech processing apparatus includes a first microphone that inputs a first mixture sound including desired speech and noise and outputs a first mixture signal, a second microphone that is opened to the same sound space as that of the first microphone, inputs a second mixture sound including the desired speech and the noise at a ratio different from the first mixture sound, and outputs a second mixture signal, a first sound collector including a concave surface that collects the first mixture sound to the first microphone, a second sound collector including a concave surface that collects the second mixture sound to the second microphone and disposed in a direction different from the first sound collector, and a noise suppression circuit that suppresses an estimated noise signal based on the first mixture signal and the second mixture signal and outputs a pseudo speech signal. With this arrangement, it is possible to, in a single sound space where desired speech and noise mix, collect the desired speech and the noise, correctly estimate the noise, and reconstruct pseudo speech close to the desired speech.

摘要： From a mixed signal in which a first signal and a second signal are mixed, the second signal is removed at low processing cost and without delay. As a result, an estimated first signal which has low residue of the second signal and low distortion is obtained.An estimated first signal is generated by subtracting a pseudo second signal which is estimated to be mixed in a first mixed signal in which a first signal and a second signal are mixed from the first mixed signal. The pseudo second signal is obtained by a first adaptive filter using a second mixed signal in which the first signal and the second signal are mixed in a different proportion from the first mixed signal. A coefficient update amount of the first adaptive filter is made smaller as compared with a case when the estimated first signal is smaller than the first mixed signal, in case the estimated first signal is larger than the first mixed signal.

摘要： A laser machine includes a laser oscillator, a cooler for cooling the laser oscillator, and a control unit for controlling the laser oscillator and the cooler. The control unit includes a controller that stops base discharge of the laser oscillator at a time when a specified time has elapsed from a stop of laser light emission by the laser oscillator. According to the laser machine, since base discharge of the laser oscillator is stopped after the specified time has elapsed from the stop of laser light emission, wasteful energy (power) consumption of the laser oscillator in a standby state can be restricted.
