Patents by Inventor Naoki Uejima

Naoki Uejima has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12191095
    Abstract: An electromagnetic relay device includes a mover, a plunger, and a solenoid unit that causes the plunger to reciprocate. The mover includes a movable contact movable to abut onto or separate from a stationary contact. The plunger causes the mover to reciprocate to accordingly cause the movable contact to abut onto or separate from the stationary contact. A heat-resistant member is interposed between the insulator and the mover. The plunger enables indirect abutment onto the mover through the insulator and the heat-resistant member. A heat-resistant temperature of the heat-resistant member is set to be higher than that of the insulator.

  • Patent number: 12009170
    Abstract: A press-fit fixing portion fixes a drive unit and a relay unit by press-fitting a claw portion and the recess portion. A sealing member is provided on an outside of the relay unit and the drive unit. An inner cover forms a sealed space for sealing an arc-extinguishing gas together with the sealing member. An electromagnetic relay is configured to make it possible both an adjustment of a press-fitting amount of the claw portion and the recess portion and an adjustment of the gap between a ceramic insulator at an end of a shaft and a movable element by making each of the relay unit and the drive unit in a manufacturing process to the same state as in when a magnetizing coil is energized.

  • Patent number: 8254126
    Abstract: An electronic circuit device includes a bus bar, a base component and an electronic component. The bus bar has an external connector terminal capable of receiving electric power from an external power source. The base component has a metallic heat radiation portion and is disposed to oppose the bus bar. The electronic component is held between the bus bar and heat the radiation portion of the base component. The bus bar further includes fixing terminals extending toward the base component. The fixing terminals are fixed to the base component to constitute fixing portions. The fixing portions are configured to have elasticity and exert a restoring force such that a distance between the bus bar and the base component reduces. The electronic component is in pressure contact with the bus bar and the base component by the restoration force of the elasticity of the fixing portions.
