Abstract: In a coil component, a shield layer is provided after the unevenness of the surface of an element body is smoothened by the surface being covered with an insulating layer. A Cu layer of the shield layer is provided on a smooth surface, and thus a thickness variation can be suppressed and the Cu layer can be formed with a substantially uniform thickness. In the coil component, a point where the shield layer is thin or a point lacking the shield layer is unlikely to be generated and a functional degradation of the shield layer is effectively suppressed.

Abstract: A video signal processor, having an input receiving unit for selectively receiving either of a baseband video signal and a composite video signal are selectively input as an input video signal thereto, a 1H delay unit for delaying the selected input video signal by one line period (1H), an inter-line non-correlation component extractor for extracting inter-line non-correlation components between the input video signal and the 1H delay signal from the 1H delay unit, an inter-frame non-correlation component remover for removing inter-frame non-correlation components from the selected input video signal, a first subtractor responsive to the selection of the baseband video signal for subtracting the inter-line non-correlation component from the baseband video signal processed the inter-frame non-correlation component removal at the inter-frame non-correlation component removing means to result noise-reduced baseband video signals, a second subtractor responsive to the selection of the composite video signal the i

Abstract: A combustor inner tube 102 or a burner 101 provided on the upstream side of a tail pipe 103 having a straight or substantially straight axis is disposed at an angle with respect to the axis of tail pipe 103, by which a secondary flow is produced in combustion gas. Thereby, low-temperature gas at the outer peripheral portion is mixed with high-temperature gas at the central portion so that the gas temperature distribution is made uniform.

Abstract: In a gas turbine combustor of the present invention, a pilot fuel nozzle is composed of at least two systems with different hole diameters, and the fuel flow rate of each system can be controlled independently. Also, even if the operation of main burners is switched in accordance with high or low load, the pilot fuel is selected accordingly. Further, the pilot fuel differential pressure is kept high to effect stable supply of fuel, and stable combustion is maintained.

Abstract: A gas turbine combustor suppresses the generation of NOx by mixing a fuel and air homogeneously. A pilot nozzle is provided at the center of the gas turbine combustor. A plurality of main nozzles surround the pilot nozzle. A diverging cone projects from the vicinity of the injection port of the pilot nozzle such that the flame from the main nozzles is sustained by the pilot nozzle and NOx is suppressed. The main nozzles can be provided upstream of the injection port of the pilot nozzle in which case an annular premixing nozzle having a throttled exit end is disposed downstream of the main nozzles. The main nozzle may also be in the form of a fuel nozzle having a plurality of tubes, a gaseous fuel being injected through one of the tubes, and liquid fuel being injected into the annular premixing nozzle through the other of the tubes so that the liquid fuel is atomized to mix the fuel and air homogeneously.

Abstract: A high-voltage generator employing a piezoelectric transformer has an inverter having input and output terminals connected to input terminals of the piezoelectric transformer, respectively; a feedback resistor connected to the input terminals of the piezoelectric transformer in parallel with the inverter; and first and second capacitors. The first capacitor is connected between the input terminal of the inverter and a ground. The second capacitor is connected between the output terminal of the inverter and the ground. The inverter, feedback resistor, and capacitors form a self-exciting oscillator to drive the piezoelectric transformer so that the piezoelectric transformer produces a high-voltage output. Since the inverter, feedback resistor, and capacitors are small, thin and light, the high-voltage generator as a whole is also small, thin and light.
