Abstract: An optical transceiver that reduces the EMI noise leaked therefrom is disclosed. The optical transceiver provides a metal housing, an optical subassembly, and an electronic circuit. The metal housing includes a first space to install the electronic circuit, and a second space to install the optical subassembly. At least the first space has inner surfaces having a corrugated shape to reduce the resonance of the electromagnetic waves.

Abstract: A barbecue grill comprising a grilling surface, a hood, a handle for opening the hood, and a lighting device interconnected with the handle. The lighting device is mounted in such a way that when the hood is opened, the lighting device can be used to illuminate the grilling surface.

Abstract: An optical transceiver that reduces the EMI noise leaked therefrom is reduced is disclosed. The optical transceiver of the invention provides a metal housing, an optical subassembly, and an electronic circuit. The metal housing includes a first space that installs the electronic circuit and a second space that installs the optical subassembly. The first space and the second space are electrically shielded to each other, in addition that both spaces are shielded from the external. In the optical transceiver of the invention, even the second space provides the optical path to the optical connector, which becomes a definite leak path for the EMI noise, the leakage from the first space to the external through the optical path is prevented.

Abstract: Applicants have invented a new low temperature method (50.degree. C. to 500.degree. C.) to deposit and grow microelectronic thin films using cold cathode electron beams to initiate and sustain both gas phase and surface chemical reactions. The new method uses electron beams generated by glow discharge electron guns. Secondary electrons are emitted from these electron guns following ion and fast neutral bombardment upon cathode surfaces and secondary electrons so formed are accelerated in the cathode sheath.Our method uses the plasma generated electron beams to decompose reactant molecules directly by electron impact and indirectly by the vacuum ultraviolet radiation generated following rare gas electron collisions in the beam region. The reactant molecules can be in the gas phase or adsorbed on substrate surfaces. The electron beams are spatially confined and excite only a localized region above the substrate so that direct plasma bombardment of the substrate is avoided.
