摘要： A voltage-command correction-value computation unit outputs a correction value for correcting a voltage command value according to a bus voltage. A multiplier calculates a voltage command value acquired by correcting the voltage command value based on the correction value. A voltage-command generation unit generates and outputs three-phase voltage command values based on the corrected voltage command value calculated by the multiplier and a phase. A PWM-signal generation unit generates six drive signals corresponding to switching elements of an inverter based on the three-phase voltage command values outputted by the voltage-command generation unit and a carrier signal. The PWM-signal generation unit outputs the generated drive signals to the corresponding switching elements of the three-phase inverter, to cause the inerter to generate a high-frequency AC voltage.

摘要： A selection unit switches between a phase θp and a phase θn different from the phase θp substantially by 180 degrees, and outputs one of them in synchronization with a carrier signal. A voltage-command generation unit generates and outputs three-phase voltage command values Vu*, Vv* and Vw* based on the phase outputted by the selection unit. A PWM-signal generation unit generates three-phase voltage command values Vu*′, Vv*′ and Vw*′ by correcting the three-phase voltage command values Vu*, Vv* and Vw* outputted by the voltage-command generation unit according to a predetermined method, and generates six drive signals corresponding to switching elements of the inverter based on the three-phase voltage command values Vu*′, Vv*′ and Vw*′ and the carrier signal. The PWM-signal generation unit outputs the generated drive signals to the corresponding switching elements of the three-phase inverter, to cause the inverter to generate a high-frequency AC voltage.

摘要： When a compressor is in a stopped state and an outside air temperature change rate Tah exceeds zero, a first heating operation is started, and a heating capacity of a compressor heating portion is set in a range not more than a heating capacity upper limit Pmax based on the outside air temperature change rate Tah. A remaining refrigerant liquid amount Ms condensed in the compressor that had not been evaporated is acquired based on the outside air temperature change rate Tah and the heating capacity. If the outside air temperature change rate Tah is zero or below and the remaining refrigerant liquid amount Ms exceeds zero while the compressor is in a stopped state, a second heating operation is started, the compressor heating portion 10 is controlled based on the remaining refrigerant liquid amount Ms, and the refrigerant condensed in the compressor 1 is evaporated.

摘要： The germination of seeds is improved by treating the seeds with a solid-form super absorbent polymer that has absorbed water. Super absorbent polymer particles that contain an amount of water such as about 5 to 7 times their weight that is significantly less than the amount of water they are able to absorb such as about 80-120 times their weight and do not substantially adhere to each other are mixed with seeds to form a mixture that may contain a volume ratio of seeds to polymer particles of 0.2 to 5:1. The mixture is stirred while supplying air or gaseous oxygen into the mixture for a time and at a temperature sufficient to cause the seeds to imbibe sufficient water to enhance their vigor for sprouting, but insufficient to cause sprouting. The mixture is sieved to obtain seeds having essentially no adhering polymer residue of the particles, after which the seeds may be dried. The polymer particles may be spherical, and before absorbing water have a size of 50 to 300 .mu.m. A fine powder of hydrophobic material such as silica, calcium stearate, magnesium stearate or barium stearate may be coated on the polymer particles before or after absorbing water in an amount of 0.1 to 5 weight percent to further prevent adhesion between the particles.

摘要： A heat pump device includes a compressor including a motor, a heat exchanger, an inverter, and an inverter control unit. The inverter control unit generates a drive signal for the inverter. When the compressor is heated, the inverter control unit applies, to the motor, a high-frequency voltage with which the motor cannot be rotationally driven; estimates a magnetic pole position indicating a stop position of a rotor of the motor; determines an amplitude and a phase of a voltage command based on an estimation result of the magnetic pole position and a necessary amount of heat, and generates a drive signal.

摘要： A heat pump device includes an inverter control unit outputting PWM signals to an inverter; a current detection unit detecting a current value flowing in the inverter and outputting the current value after reducing a current value having a first frequency or higher in detected current value; and a drive-signal stop unit that, when the current value output from the current detection unit is equal to or larger than an interruption level, stops output of PWM signals to the inverter. Particularly, the inverter control unit generates a voltage command value such that the voltage command value becomes a value equal to or larger than a lower limit determined according to the first frequency and generates PWM signals based on generated voltage command value and a carrier signal, thereby causing a voltage output time to the motor to be a predetermined time or longer.

A drive-signal generation unit, based on an output from the voltage generation unit generates drive signals corresponding to respective switching elements of an inverter, and outputs respective generated drive signals to the corresponding switching elements of the inverter, and generates a high-frequency AC voltage in the inverter.
