  • Patent number: 10491134
    Abstract: An electrical machine includes a first substrate, a second substrate, and a conduction support. The first substrate has a mounting surface. The second substrate is disposed in an overlay direction from the first substrate. The conduction support electrically grounds the second substrate and supports the second substrate while keeping approximately no contact with the mounting surface of the first substrate.

  • Patent number: 10135379
    Abstract: An LED indicator 4 connected to industrial machinery including an inverter 1, includes: an LED substrate 8 into which a display control signal according to a state relating to the industrial machinery is input; and a plurality of displays 31, 32, and 33 configured to display in a lighting state corresponding to a state of the industrial machinery, on the basis of the display control signal input by the LED substrate 8. The plurality of displays 31, 32, and 33 each include a partially circular-arc shape, and are generally arranged in an approximately annular shape. The plurality of displays 31, 32, and 33 include the two displays 31, 32 that generally configure a half ring at one side of the approximately annular shape, and the one display 33 that generally configures a half ring at the other side of the approximately annular shape.

  • Patent number: 10039215
    Abstract: A power converter includes a housing, a circuit element, and a cover. The housing includes a first space and a second space. In the first space, a circuit substrate is disposed. In the second space, a passage for a cooling fluid is disposed. The circuit element is disposed on the circuit substrate in the first space and protrudes into the second space. The cover covers at least a portion of the circuit element and includes a first portion and a second portion. The first portion protrudes from near the circuit substrate into the second space, and defines a first region that has a first area. The second portion protrudes from the first portion, and defines a second region that has a second area. The first area is larger than the second area as viewed from a direction in which the circuit element protrudes.
