Abstract: An outdoor unit of an air-conditioning apparatus includes a compressor, a heat exchanger, and a controller. The controller includes a compressor driving circuit configured to drive the compressor, a harmonic suppressing unit configured to suppress harmonics in the compressor driving circuit, and a housing containing the compressor driving circuit and the harmonic suppressing unit. The housing has a first section having ventilation holes that allow communication between the outside and the inside, and a second section constituting a frame outside the first section. The first section contains the harmonic suppressing unit and a fan configured to blow air from inside the first section to the outside through the ventilation holes. The second section contains the compressor driving circuit.

Abstract: To provide an electron gun that can improve the focus characteristics of a cathode ray tube by reducing the working area of the cathode, a cathode ray tube equipped with this electron gun that has favorable focus characteristics, and an image display device comprising this cathode ray tube that can achieve favorable images. An area on the electron emission surface of the cathode K that meets the beam hole (11A) of the first grid (11) forms an electron gun in closest proximity to the first grid (11). Provide a cathode ray tube equipped with this electron gun and further provide an image display device formed by this cathode raytube.

Abstract: The present invention provides an electron gun which is excellent in voltage-resistant characteristics and has a first electrode less deformed, and a method of manufacturing the same.

Abstract: A capacitor is disclosed having two capacitor elements of MIS structure, the capacitor elements being connected in a zigzag manner to realize a balanced parallel connection for the capacitor elements. A circuit having a pair of balanced impedance branches, the branches being bridged by the balanced parallel capacitor disclosed above, resultantly sustains the impedance branches balanced regardless of the amount of the parasitic capacity involved.
