    • A carrier particle which includes a core and a coating layer formed on the surface of the core. The coating layer is made of a coating material including: an organic compound (A) having a functional group other than an Si(OR.sup.1) group, where R.sup.1 is a hydrogen atom, a lower alkyl group or an acyl group; a compound (B) and/or a hydrolytic condensation product thereof, having a functional group having reactivity with the functional group of the organic compound (A), and an Si(OR.sup.1) group; an organometallic compound (C) and/or a hydrolytic condensation product thereof; and a solvent (D). The carrier particles of the present invention, enable toner particles to be sufficiently charged even at high temperature and high humidity, so that an image with no fog can be formed. In addition, the carrier particle has high durability. There is no unnecessary attachment of the toner particles onto the carrier particles, so that the problems of carrier particle contamination and spent toner never arise.

    • Disclosed is an inverter having improved power conversion efficiency. The inverter (200) converts direct current power supplied from a plurality of direct current power supplies (V1, V2) having different voltages into alternating current power. The inverter (200) is provided with a control unit (20). The control unit (20) generates modified sine waves using a power supply voltage (E1) of the power supplied from the first direct current power supply (V1), a power supply voltage (E2) of the power supplied from the second direct current power supply (V2), and a potential difference (E1−E2) between the two power supply voltages. The control unit (20) generates the modified sine waves by controlling H bridge circuits provided for the direct current power supplies (V1, V2), respectively.
    • 公开了一种具有提高的功率转换效率的逆变器。 逆变器(200)将从具有不同电压的多个直流电源(V1,V2)提供的直流电力转换成交流电力。 逆变器(200)设置有控制单元(20)。 控制单元(20)使用从第一直流电源(V1)供给的电力的电源电压(E1),从第二直流电力供给的电力的电源电压(E2)来生成修正正弦波 电源(V2)和两个电源电压之间的电位差(E1-E2)。 控制单元(20)分别通过控制为直流电源(V1,V2)提供的H桥电路来产生修正的正弦波。
