  • Patent number: 11685087
    Abstract: A conductive member module has a pair of conductive members formed in a plate shape and facing each other, and a sealing part. The conductive member module is produced by performing an accommodation step, a sealing step, and an extraction step. In the accommodation step, the two individual conductive members are sandwiched in the facing orientation thereof by outer support members abutting outer surfaces of the conductive members, and inner support members abutting inner surfaces of the conductive members. Outer recesses are formed in the outer surfaces by the outer support members, and inner recesses are formed in the inner surfaces by the inner support members. The outer recesses are deeper in the Z direction than the inner recesses.

  • Patent number: 11660793
    Abstract: A conductive member module has a pair of conductive members formed in a plate shape and facing each other, and a sealing part for sealing the pair of conductive members. The conductive member module is produced by performing an accommodation step, a sealing step, and an extraction step. In the sealing step, the conductive members are sealed with a resin injected into a die while a force is applied by the resin to the individual conductive members in directions to approach each other in a facing orientation of the pair of conductive members.

  • Patent number: 11623376
    Abstract: Performed are an accommodation step of accommodating a pair of conductive members in a die, a sealing step of injecting a resin to seal the conductive members, and an extraction step of extracting a conductive member module. In the sealing step, the conductive members are sealed while a force is applied by the resin injected into the die to the individual conductive members in directions away from each other, and the individual conductive members are supported by support members disposed outside.

  • Patent number: 6295487
    Abstract: A hybrid vehicle (1) including an internal combustion engine and electric motors and selectively uses them as a running drive source according to a running state. When one of wheels (5) driven by an engine (7) skids to rotate excessively, a motor (13) connected to that wheel is caused to make a regenerative operation to remedy the skid of the wheel, and running traction made insufficient due to the skid is compensated by driving another wheel (4) by a motor (12) of another wheel by using electric energy recovered by the regenerative operation.
