    Abstract: An inverter device uses an inverter to convert DC voltage supplied from a rectifying component to AC voltage and applies the AC voltage to an inductive load. The inverter device includes a shunt resistor provided on a direct-current link interconnecting the rectifying component and the inverter, a first terminal passing current to the shunt resistor, a second terminal to which the current from the shunt resistor flows, and a printed board having a conductive pattern with first and second conductive pattern components joining the shunt resistor and the first and second terminals, respectively. The first conductive pattern component includes a first central region connecting right and left side ends of the shunt resistor to right and left side ends of the first terminal, and first right and left side protruding regions. A ratio of areas of the first left and right side protruding regions is 0.6 to 1.6.

    Abstract: A communication system includes a first device, second devices, and a communication line providing a serial connection from the first device to the second devices to establish a communication connection. An address setting device of the communication system is configured to set addresses of the second devices. The address setting device includes a communication controller. The communication controller is configured to transmit a transmission signal toward the second devices through the communication line and change at least one of an amplitude or a frequency of the transmission signal, and associate the addresses of the second devices with connection precedence of the second devices to the first device based on a reception signal received through the communication line.

    Abstract: An equipment installation support system is usable to support setting of a plurality of pieces of equipment intended to be installed in a plurality of buildings. The support system includes a plurality of recording tools, and a server. Each recording tool is assigned to one of the plurality of pieces of equipment and includes a medium having recorded information concerning the assigned one of the plurality of pieces of equipment. The server manages the plurality of pieces of equipment. A specific piece of equipment is intended to be installed in a specific building among the plurality of buildings and has a configuration to adjust a room environment of the specific building. A specific recording tool is assigned second identification information that is assigned to the specific piece of equipment and identifies the specific piece of equipment from pieces of equipment other than the specific piece of equipment.

    Abstract: A voltage detection probe includes an electrode configured to detect a voltage applied to a wire, and a clip portion freely attachable to and detachable from the wire. The clip portion has a fitting concave portion into which the wire is to be fitted, the clip portion being elastically deformable to widen an opening of the fitting concave portion. The clip portion is configured to retain, by an elastic force, the wire fitted through the opening into the fitting concave portion to cause the electrode to be disposed along an outer peripheral surface of the wire.

    Abstract: An air conditioning system includes an outdoor unit and an indoor unit connected to the outdoor unit through an air conditioning communication line. The outdoor unit includes: a control unit; a compressor; a fan; a compressor inverter; a fan inverter; a heat exchanger; and valves of various types. The control unit of the outdoor unit has a coupling capacitor and a noise-cutting transformer which are between a communication circuit and the air conditioning communication line.
