  • Publication number: 20240177894
    Abstract: A laminated varistor includes a sintered body and first to third internal electrodes provided inside the sintered body. The first internal electrode includes a first facing part facing the third internal electrode in a third direction, and a first connecting part connecting the first facing part and the first external electrode. The second internal electrode includes a second facing part facing the third internal electrode in the third direction, and a second connecting part connecting the second facing part and the second external electrode. The first connecting part includes a first connection portion connected to the first external electrode, and a first narrow part having a dimension in a second direction smaller than the first connection portion. The second connecting part includes a second connection portion connected to the second external electrode, and a second narrow part having a dimension in the second direction smaller than the second connection portion.

  • Publication number: 20240177895
    Abstract: A first internal electrode includes a pair of first connecting parts extending from a first end surface along a first direction to be connected to a first external electrode, and a first facing part provided between the pair of first connecting parts. A second internal electrode includes a pair of second connecting parts extending from a second end surface along the first direction to be connected to a second external electrode, and a second facing part provided between the pair of second connecting parts. A third internal electrode includes a third facing part disposed along the first direction. The third facing part overlaps the first facing part and the second facing part. A first end of the third facing part is disposed between the pair of first connecting parts, and a second end of the third facing part is disposed between the pair of second connecting parts.

  • Publication number: 20240151654
    Abstract: A communication hole inspection device for inspecting a communication hole in a structure, a casting surface being formed on an inner surface of the hole, said communication hole inspection device having: a light-emitting body that is arranged in a portion of the communication hole and emits a beam of light; a light-receiving body that is arranged in a different portion of the communication hole and receives the light beam from the light-emitting body; a rotation mechanism for changing the rotation angle of the light-emitting body and thereby changing the light beam received by the light-receiving body; and a determination unit for determining the open state of the communication hole at least on the basis of based on the light beam received by the light-receiving body when the rotation angle of the light-emitting body is set at a first angle, and at a second angle different from the first anile.

  • Publication number: 20240105365
    Abstract: An object of the present disclosure is to provide a multilayer varistor with the ability to reduce the chances of causing crosstalk between external terminals. Inside a sintered body having the shape of a rectangular parallelepiped, of which the longitudinal axis is aligned with a first direction, a first facing portion and a second facing portion are provided to interpose a third facing portion between themselves. At least one of a first side surface or a second side surface is provided with a first external electrode connected to the first facing portion, a second external electrode connected to the second facing portion, and a third external electrode and a fourth external electrode connected to the third facing portion. In the first direction, the first external electrode and the second external electrode are interposed between the third external electrode and the fourth external electrode.

  • Patent number: 11890638
    Abstract: A powder supply device includes a hopper accommodating powder, a cylindrical roller provided below the hopper and rotatable around a rotational axis, and a wall surface storing the powder in a space between the roller and the wall surface. The powder supply device moves the powder stored between the roller and the wall surface in a rotation direction of the roller and drops the powder by the roller rotating. A plurality of groove portions extending in an axial direction are formed in a peripheral surface of the roller. At least one of the groove portions is formed such that a capacity allowing the powder to be accommodated changes in the axial direction.
