20160027973 | LIGHT-EMITTING DEVICE, PRODUCTION METHOD THEREFOR, AND DEVICE USING LIGHT-EMITTING DEVICE - A light-emitting device, including: a pair of light-transmissive insulator sheets each provided with a light-transmissive electroconductive layer, or a pair of alight-transmissive insulator sheet equipped with light-transmissive electroconductive layers and alight-transmissive insulter sheet free from a light-transmissive electroconductive layer, disposed opposite to each other so as to form a region between the pair; at least one light-emitting semiconductor element each provided with a cathode and an anode which are individually and electrically connected to one of the light-transmissive electroconductive layers, and a light-transmissive elastomer, disposed between the pair of light-transmissive insulator sheets so as to fill the region in combination; wherein the light-transmissive elastomer is present at least locally between the cathode and anode, respectively, of the light-emitting semiconductor element and the light-transmissive electroconductive layers, and the light-transmissive elastomer is also present at concavities of the cathode and anode surfaces. | 01-28-2016 |
20150123537 | PLASMA EMISSION DEVICE, AND ELECTROMAGNETIC WAVE GENERATOR USED THEREIN - A plasma emission device in an embodiment includes: an electromagnetic wave generator; a waveguide transmitting an electromagnetic wave emitted from the electromagnetic wave generator, an antenna receiving the electromagnetic wave transmitted through the waveguide; an electromagnetic wave focuser which is irradiated with the electromagnetic wave from the antenna; and an electrodeless bulb disposed in the electromagnetic wave focuser. A light-emitting material filled in the electrodeless bulb is excited by the electromagnetic wave focused by the electromagnetic wave focuser to perform plasma emission. The electromagnetic wave generator includes a cathode part and an anode part. A maximum output efficiency of the electromagnetic wave to be generated with an input power of 700 W or less is 70% or more. | 05-07-2015 |
20110234093 | MAGNETRON AND MICROWAVE OVEN THEREWITH - A magnetron has an anode cylinder, ten vanes, three strap rings. The ten vanes are fixed to an inner surface of the anode cylinder and arranged in a radial pattern of which center is at an axis of the anode cylinder. Each of the three strap rings connects vanes that are alternatively arranged. A first strap ring and a third strap ring are arranged on a first end of the vanes in a direction of axis, and a second strap ring is arranged on a second end that is opposite to the first end. Outer diameter of the second strap ring is equal to inner diameter of the first strap ring and outer diameter of the third strap ring is equal to inner diameter of the second strap ring. | 09-29-2011 |
20100071198 | METHOD FOR MANUFACTURING THERMAL HEAD - A method for manufacturing a thermal head, including: forming a resistance heating element and an electrode on an insulating substrate, the resistance heating element emitting heat by a current flowing the resistance heating element, the electrode being connected to the resistance heating element; forming a corrosion prevention layer on the resistance heating element and the electrode; annealing the resistance heating element; adjusting an electrical resistance of the resistance heating element; and forming a protective layer on the corrosion prevention layer, the protective layer having glass as a main component. The annealing is implemented prior to the adjusting. The forming the corrosion prevention layer is implemented prior to the annealing. | 03-25-2010 |
