[Object] Provided are: a Zn—Si—O-based oxide sintered body, which suppresses abnormal discharge and so forth when used as a sputtering target, or suppresses a splash phenomenon when used as a tablet for vapor deposition; a method for producing the Zn—Si—O-based oxide sintered body; and the like.[Solution] The Zn—Si—O-based oxide sintered body contains zinc oxide as a main component and Si, and is characterized in that a Si content is 0.1 to 10 atomic % with an atomic ratio of Si/(Zn+Si), the Si element is contained in a wurtzite-type zinc oxide phase to form a solid solution, and the oxide sintered body does not contain a SiO2 phase and zinc silicate (Zn2SiO4) as a spinel-type composite oxide phase. In producing the sintered body by pressing a granulated powder obtained from a ZnO powder and SiO2 powder, which are raw material powders, and sintering the compact, the method for producing the sintered body is characterized by including the steps of: raising a temperature in a sintering furnace in a temperature range from 700 to 900° C. at a rate of temperature rise of 5° C./minute or more; and sintering the compact from 900° C. to 1400° C. in the sintering furnace.

A transparent electrically conductive substrate having a high photovoltaic conversion efficiency surface electrode, and a method for its manufacture, are disclosed. A thin-film solar cell and a method for its manufacture are also disclosed. An indium oxide based amorphous transparent electrically conductive film is formed on the substrate as an underlying film 21 and a zinc oxide based crystalline transparent electrically conductive film is formed on the so formed amorphous transparent electrically conductive film to form a surface electrode 2 of an optimum uneven surface structure. As a consequence, the surface electrode 2 having a high light confining effect may be provided and a thin-film solar cell 10 may be provided which exhibits higher photovoltaic conversion efficiency (FIG. 1)
摘要:
A coaxial dielectric filter comprising a straight cutoff waveguide, at least two coaxial dielectric resonators disposed coaxially or substantially coaxially and at an interval in the cutoff waveguide in its lengthwise direction, a rod-like input-side antenna whose leading end stands close, or inserted, to the inside of an input-side inner conductor of the coaxial dielectric resonator disposed on the input side, and a rod-like output-side antenna whose leading end stands close, or inserted, to the inside of an output-side inner conductor of the coaxial dielectric resonator disposed on the output side. This filter is characterized in that an adjacent-side end of at least one of coaxial dielectric resonators adjacent to each other forms a slope which is inclined with respect to the cutoff waveguide in its cross section perpendicular to the lengthwise direction.In the adjustment of distance between the coaxial dielectric resonators adjacent to each other, the distance between the coaxial dielectric resonators on their adjacent sides can be adjusted simply not only when the coaxial dielectric resonator provided with the slope is moved in the lengthwise direction of the cutoff waveguide but also when it is moved in the width direction of the cutoff waveguide.

A magnetic compensating circuit includes a magnetic sensor (1), a control circuit (2) for generating a signal for magnetic compensation, and coils (3) for magnetic compensation. The magnetic sensor has a pair of amorphous magnetic substance wires (101) arranged in parallel, coils (102) for providing the pair of amorphous magnetic substance wires with bias magnetic fields in directions opposite to each other, a high-frequency power source (105) for supplying the pair of amorphous magnetic substance wires with high-frequency currents, and circuits (106, 107, 108, 109) for outputting a potential difference derived from the output of the pair of amorphous magnetic substance wires. Thus, this magnetic compensating circuit is capable of detecting a minute external magnetic field with high accuracy.
