  • Publication number: 20130033166
    Abstract: A lighting apparatus includes a light source module, a power supply circuit section supplying power to the light source module, a heat radiating section accommodating the power supply circuit section inside and radiating the heat generated in the power supply circuit section, a base connected to an external power supply, and an insulating ring provided between the heat radiating section and the base and making electrical insulation. With regard to the lighting apparatus, the insulating ring is a thermal conductor. Since the insulating ring functions as the thermal conductor, the heat generated in the power supply circuit section is transferred to the heat radiating section and the base via the insulating ring so that the heat is radiated to outside from the heat radiating section and the base.

  • Patent number: 7775041
    Abstract: A Stirling engine, wherein the inner yoke of a linear motor is installed on the outer peripheral surface of a cylinder. To keep a proper pressure balance between a compression space on one end side of a displacer and a back pressure space on the outer peripheral side of the cylinder, a first flow passage is formed in the piston starting at the compression space side end face toward the outer peripheral surface and a second flow passage allowing the first flow passage to communicate with the back pressure space is formed in the cylinder. The second flow passage is composed of a through hole that penetrates the wall of the cylinder in a radial direction and a communication passage formed between the outer peripheral surface of the cylinder and the inner peripheral surface of the inner yoke to allow the through hole to communicate with the back pressure space.
