  • Patent number: 7309270
    Abstract: A spacer on which static electricity is restricted and an electron beam apparatus in which the spacer is provided. In the electron beam apparatus comprising an electron source provided with electron emission devices, a face plate provided with anodes and spacers installed between the electron source and the face plate, unevenness is formed on the surface of the spacer substrate, and further a thin film which has a smaller thickness than a roughness. This makes possible the restriction of incident angle multiplication coefficient for the primary electrons whose energy is lower than the second cross-point energy of a resistive film. The electron beam apparatus provided with the above spacer is excellent in display definition and long-term reliability since the display of light emission points and the creeping discharge accompanying the static electricity can be restricted due to the spacer.

  • Patent number: 7306502
    Abstract: A spark plug is provided which ensures the reliability of a weld between a noble metal chip and a ground electrode as well as higher durability and ignitability of fuel. The ground electrode is joined to a metal shell, after which the noble metal chip is laser-welded to the ground electrode. The laser welding is achieved by emitting laser beams around an interface between the noble metal chip and the ground electrode outside a given angular range within which the metal shell will be an obstruction to the traveling of the laser beams. Specifically, the laser beams are emitted without any optical interference with the metal shell. This permits the angle between the orientation of each of the laser beams and the surface of the ground electrode to be minimized regardless of the metal shell, thus ensuring a desired depth of the fused portions in the noble metal chip.
