| 20090243531 | INVERTER APPARATUS - An inverter apparatus comprises an inverter circuit using pairs of switching elements. The pseudo AC voltage of each phase of this inverter circuit is controlled by pulse modulation using pulses generated by a PWM generator, and the pseudo AC voltages are applied to a power supplied load. The average voltage of respective phases of the output voltages applied to the power supplied load is detected as a virtual neutral voltage corresponding to the neutral voltage of the power supplied load by detecting the voltage at a common node where the phases of a voltage detecting circuit provided between the inverter circuit and the power supplied load are connected. The detected virtual neutral voltage is fed back for controlling the output duty of each phase by the PWM generator. Thus the output voltage of each phase from the inverter circuit is controlled so as to become a target output voltage. The target output voltage can be accurately obtained stably at all times. | 10-01-2009 |
| 20100172765 | ELECTRIC COMPRESSOR CONTROL DEVICE - Provided is a device for controlling power supply from an inverter having a semiconductor switching element to an electric compressor having a built-in motor. The device includes: means for calculating a starting current value required for starting the compressor from the pressure at the discharge side circuit of the compressor; means for calculating a permitted current value of the semiconductor switching element from the temperature of the inverter installation portion; and means for comparing the calculated compressor starting current value to the permitted current value of the semiconductor switching element so as todetermine whether to permit a start of the compressor. Thus, it is possible to appropriately start the electric compressor without using a semiconductor switching element requiring a greater current capacity than is necessary in the inverter. This reduces the size and the cost of the electric compressor. | 07-08-2010 |

| 20120015377 | METHOD AND APPARATUS FOR MEASURING BIOGENOUS BIOLOGICALLY ACTIVE SUBSTANCE - Provided is an assay method and an assay device whereby assay time can be largely shortened in the case of detecting a physiologically active substance of biological origin. The aggregation start time of a liquid mixture of an assay sample with LAL is determined. From this aggregation start time, the physiologically active substance is detected or the concentration thereof is measured. The liquid mixture of the assay sample with LAL is stirred with, for example, a magnetic stirrer to form gel particles. Next, the scattered light intensity of laser light scattered by these gel particles is measured. Then, the frequency distribution of the scattered light intensity fluctuation is obtained. Based on the temporal change in the frequency distribution shape, the aggregation start time of the liquid mixture of the assay sample with LAL is determined. | 01-19-2012 |
