  • Publication number: 20080289802
    Abstract: A radiator includes an inlet line and an outlet line for a coolant to be cooled, and a plurality of flow passage units each being connected to the inlet and outlet lines respectively in parallel with adjacent flow passages with a space therebetween. Due to this configuration, it is possible to attain a high cooling capability with a small flow speed of the coolant, which is enabled by increasing the number of the flow passage units with respect to a certain flow rate passing through the inlet and outlet lines. This radiator can be employed for a cooling system together with a fan blowing air toward the flow passage units of the radiator, a coolant jacket for absorbing heat from a heat source such as a CPU, and a fluid pump for circulating the coolant between the coolant jacket and the radiator.

  • Patent number: 7178922
    Abstract: A lamp has a deformed lamp reflector and a lamp front glass. The deformed lamp reflector is made by deforming an ellipsoid of revolution of a conventional lamp reflector into an aspherical reflection surface rotationally symmetrical with respect to an optical axis. The lamp front glass is obtained by deforming at least one of an incident surface and outgoing surface of a conventional lamp front glass into an aspherical lens surface rotationally symmetrical with respect to the optical axis. A light flux emitted from the center point of an illuminant is reflected by the deformed lamp reflector, and output with a uniform density through all of the outgoing surface of the lamp front lens so that the light flux is condensed at focus point.

  • Patent number: 6997565
    Abstract: A lamp has a deformed lamp reflector and a lamp front glass. The deformed lamp reflector is formed by deforming a paraboloid of revolution of a conventional lamp reflector to an aspherical reflection surface which is rotationally symmetrical with respect to an optical axis. The lamp front glass is obtained by deforming the incident plane of a conventional lamp front glass to an aspherical lens surface rotationally symmetric with respect to the optical axis. A light flux radiated from the center point of the light source of an illuminant is reflected by the deformed lamp reflector, and is output through the lens as a parallel light flux having a circular cross section equal in area to the lens.
