  • Publication number: 20240072609
    Abstract: A motor includes a bottomed cylindrical housing incorporating a rotor that rotate integrally with a shaft and a stator, and an end bell having an end plate that closes an opening of the housing and a holder that is provided between the rotor and the end plate in an axial direction and to which an electrical element is attached. The end plate has an air hole penetrating the end plate in the axial direction. The holder includes an attachment portion to which the electrical element is attached, and has an insertion hole through which the shaft is inserted. At least part, of the attachment portion, overlapping the air hole when viewed in the axial direction has a cutout portion.

  • Publication number: 20230138154
    Abstract: An electronic component includes conductor layers and insulating resin layers which are alternately stacked on a substrate. One of the insulating resin layers positioned in the lowermost layer is smaller in thickness than the insulating resin layers, and the insulating resin layers are smaller in thermal expansion coefficient than the one of the insulating resin layers. Thus, an element that requires high processing accuracy, such as a capacitor, can be embedded in the insulating resin layer positioned in the lowermost layer and having a small thickness, and an element that requires a sufficient conductor thickness, such as an inductor, can be embedded in the insulating resin layers having a large thickness. In addition, since the insulating resin layers each have a small thermal expansion coefficient, the occurrence of warpage and peeling can be suppressed.

  • Patent number: 9637146
    Abstract: A coupler system includes: a coupler main body attached to a longitudinal direction end of a carbody of a railcar so as to be rotatable in a yaw direction; a curvature information acquiring portion configured to acquire curvature information of a track, the railcar being located on the track; a control portion configured to determine a target rotation angle of the coupler main body in accordance with the acquired curvature information and output a rotation signal regarding the determined target rotation angle; and a rotation angle changing portion configured to rotate the coupler main body to the target rotation angle based on the output rotation signal. When the railcar is stopped or when the railcar is traveling at a coupling speed, the control portion outputs the rotation signal to start rotating the coupler main body.

  • Patent number: 5513433
    Abstract: A spherical bearing includes an outer ring formed integrally with a rod end, an inner ring having a spherical outer peripheral surface arranged in face-to-face relation with the inner peripheral surface of the outer ring, and a flexible lubricating sheet disposed between the inner peripheral surface of the outer ring and the spherical outer peripheral surface of the inner ring. Respective central portions in both annular areas of the flexible lubricating sheet which are respectively defined between an axial center of the outer ring and one annular end of the inner peripheral surface of the outer ring and between the axial center of the outer ring and another annular end of the inner peripheral surface of the outer ring are made to undergo plastic flow and are formed to be thinner than a remaining portion of the flexible lubricating sheet.
