  • Publication number: 20200321858
    Abstract: An inverter apparatus includes a main circuit substrate, an EMC filter substrate, a control substrate, and a panel. The main circuit substrate is configured to convert electric power and includes an output terminal through which the electric power is output from the inverter apparatus. The EMC filter substrate is provided on the main circuit substrate and configured to reduce propagation of electromagnetic noise. The EMC filter substrate includes a first input terminal through which the electric power is input to the inverter apparatus. The control substrate is provided on the EMC filter substrate so that the EMC filter substrate is sandwiched between the main circuit substrate and the control substrate. The control substrate is configured to control the main circuit substrate. The panel is provided on the control substrate so that the control substrate is sandwiched between the EMC filter substrate and the panel.

  • Publication number: 20190136125
    Abstract: An organic compound represented by the following general formula is provided. In the above formula (1), R11 to R15 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an acyl group, or a halogen atom provided that at least one of R11, R13, and R15 represents the alkoxy group or the aryloxy group; and R11 to R15 may form a ring structure therebetween. R5 and R6 each independently represent an alkyl group, an aryl group, or an aralkyl group. In addition, R21 to R24 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an acyl group, or a halogen atom and may form a ring structure therebetween. The above groups except the acyl group may be substituted when necessary.
