  • Publication number: 20240178110
    Abstract: A semiconductor module includes a semiconductor device and bus bar. The device includes an insulating substrate, conductive member, switching elements, and first/second input terminals. The substrate has main/back surfaces opposite in a thickness direction, with the conductive member disposed on the main surface. The switching elements are connected to the conductive member. The first input terminal, including a first terminal portion, is connected to the conductive member. The second input terminal, including a second terminal portion overlapping with the first terminal portion in the thickness direction, is connected to the switching elements. The second input terminal is separate from the first input terminal and conductive member in the thickness direction. The bus bar includes first/second terminals. The second terminal, separate from the first terminal in the thickness direction, partially overlaps with the first terminal in the thickness direction.

  • Publication number: 20230406443
    Abstract: A front fork (1) of the present invention includes: a fork main body (2) having a vehicle body side tube (3) and an axle side tube (4); a cap (5) placed in the vehicle body side tube (3); a cylinder (6) provided inside the axle side tube (4); a rod (7) inserted into the cylinder (6) so as to be movable in an axial direction; an electric device (6) mounted inside the cylinder (6); an electric wire (9) connected to the electric device (8); a suspension spring (10) biasing the fork main body (2) in an extending direction, and an adjuster (11) capable of adjusting a support position of a spring seat (12). The electric wire (9) is drawn from the cap (5) at a position misaligned from an axial center line of the fork main body (2) to an outside of the fork main body (2). An operational portion (17) of the adjuster (11) is provided in the cap (5) at a position misaligned from the axial center line (A).

  • Publication number: 20230108079
    Abstract: A shock absorber is provided with a cylinder, a piston inserted into the cylinder and demarcating an interior of the cylinder into an extension side chamber and a compression side chamber, a piston rod joined to the piston, a damping passage, provided in the piston rod, that communicates with the extension side chamber and the compression side chamber, and a damping force adjustment valve provided in the damping passage. The damping force adjustment valve includes a damping force adjustment unit and a solenoid that drives the damping force adjustment unit to adjust a flow channel resistance. The piston rod includes a yoke into which the damping force adjustment valve is inserted, and a piston holding member mounted on the yoke. The yoke includes a through-hole opening from a side of the yoke and leading to the interior, and a groove provided on a perimeter of the yoke, extending from an anti-piston end, and leading to the through-hole.
