  • Patent number: 10850132
    Abstract: A particle therapy system in which the efficiency of extracting a beam from a synchrotron can be improved and time required for therapy can be shortened is provided. The synchrotron 10 of the particle therapy system 100 extracts a charged particle beam, which circulates in the synchrotron 10, out of the synchrotron 10 by means of a slow extraction method using the resonance of a betatron oscillation, and magnetic poles 73 included in a bending magnet 12 of the synchrotron 10 have a SIM structure that generates a magnetic field distribution that makes the horizontal tune of the charged particle more closely approach a resonant line used in the slow extraction method as the amplitude of the horizontal betatron oscillation of a charged particle included in the charged particle beam becomes larger.

  • Patent number: 8354780
    Abstract: A lamp device includes: a housing formed with heat-dissipating holes; a conductive connecting head mounted on a first side of the housing; a heat-conducting member mounted on a second side of the housing opposite to the first side, and having opposite first and second side surfaces; a lighting unit thermally contacting and mounted on the first side surface of the heat-conducting member, and covered by a transparent body; and a heat-dissipating layer made of an infrared radiating material. The heat-dissipating layer is disposed on and is in thermal contact with the second side surface of the heat-conducting member. Heat generated by the lighting unit is transmitted by the first heat-conducting member to the heat-dissipating layer, and is dissipated by the heat-dissipating layer through the heat-dissipating holes in the housing.

  • Publication number: 20120161600
    Abstract: The present invention provides templating methods for replicating patterned metal films from a template substrate such as for use in plasmonic devices and metamaterials. Advantageously, the template substrate is reusable and can provide plural copies of the structure of the template substrate. Because high-quality substrates that are inherently smooth and flat are available, patterned metal films in accordance with the present invention can advantageously provide surfaces that replicate the surface characteristics of the template substrate both in the patterned regions and in the unpatterned regions.

  • Patent number: 8193688
    Abstract: An LED lamp includes a heatsink housing (2) and an alternating current LED module (1). The alternating current LED module includes a heat conducting portion (10) combined with the heatsink housing and two electrical connections (11) electrically connected with an external power supply. Thus, the heatsink housing forms a porous structure to provide a greater heatsink effect and to quickly carry away the heat produced by the alternating current LED module to enhance the heat dissipation efficiency of the alternating current LED module. In addition, the heatsink housing is directly formed to have the profile of a common lamp housing and is provided with a metallic screw base (21), an insulating gasket (22) and a power contact plate (23) so that the heatsink housing can be mounted on a traditional receptacle to replace the conventional electric bulb.
