  • Patent number: 10660166
    Abstract: The microwave heating apparatus of the present invention enables microwaves to be propagated onto an object to be heated through a waveguide such that the microwaves propagate to a microwave space reduced by a wavelength controller which is arranged, as a solid-state object, to occupy a predetermined space in the waveguide. Thus, the microwave heating apparatus of the present invention heats the object to be heated which has been placed in the reduced space. The microwave heating apparatus of the present invention utilizes the effects of lengthening the wavelength of the microwaves propagating to the reduced space so as to be longer than the wavelength before entering the reduced space by a predetermined multiple depending on a near-cutoff condition.

  • Patent number: 8299710
    Abstract: A lamp and methods of forming are shown. In one example, a dielectric layer is formed over a gap between conductors in a plasma lamp. Electric arcing is reduced or eliminated, thus allowing tighter gaps and/or higher voltages. In one example a glass frit method is used to apply the dielectric layer. A lamp is shown with a barrier layer that prevents tarnish such as tarnish from sulfur exposure. The barrier layer reduces or prevents degradation of the lamp due to conversion of a conductor material to non-conductive tarnish material.
