Abstract: In this photoelectric conversion element wherein group III-IV compound semiconductor single crystals containing zinc as an impurity are used as a substrate, the substrate is increased in size without lowering conversion efficiency. A heat-resistant crucible is filled with raw material and a sealant, and the raw material and sealant are heated, thereby melting the raw material into a melt, softening the encapsulant, and covering the melt from the top with the encapsulant. The temperature inside the crucible is controlled such that the temperature of the top of the encapsulant relative to the bottom of the encapsulant becomes higher in a range that not equal or exceed the temperature of bottom of the encapsulant, and seed crystal is dipped in the melt and pulled upward with respect to the melt, thereby growing single crystals from the seed crystal.

Abstract: A choke coil including a coil (6) and a core (1) including a first core part (5) inserted into a central hole of the coil (6) and a plurality of second core parts (4) disposed along the outer periphery of the coil. The first core part (5) and the second core part (4) form a closed magnetic path. The second core parts (4) are shaped so that the total sum of the areas of cross sections thereof perpendicular to the axis of the coil is greater than the area of a cross section of the first core part (5). A gap part (G) is formed in the second core parts (4), and a ferrite magnet (7) that applies a magnetic bias is disposed in the gap part (G).

Abstract: Problem to be Solved To provide a choke coil that can apply an optimal magnetic bias even when the current increases and can be reduced in size, weight and cost. Solution The present invention provides a choke coil including a coil (6) and a core (1) including a first core part (5) inserted into a central hole of the coil (6) and a plurality of second core parts (4) disposed along the outer periphery of the coil, the first core part (5) and the second core part (4) forming a closed magnetic path, wherein the second core parts (4) are shaped so that the total sum of the areas of cross sections thereof perpendicular to the axis of the coil is greater than the area of a cross section of the first core part (5), a gap part (G) is formed in the second core parts (4), and a ferrite magnet (7) that applies a magnetic bias is disposed in the gap part (G).

Abstract: The present invention provides a choke coil capable of applying an optimum magnetic bias without causing degradation of magnetic characteristics and any adverse effect on a neighboring device which would be caused by a temperature rise, therefore capable of adequately accommodating higher current. A choke coil according to the present invention includes a toroid coil 6 and a core 1 in which a first core 5 inserted in the center of the coil and a second core 3, 4 disposed at an outer periphery of the coil form a closed magnetic circuit. A gap G is formed in the first core 5. A magnet array applying a magnetic bias is placed in the gap G. The magnet array is formed by a plurality of submagnets 7 separated in a plane perpendicular to a direction in which a magnetic flux from the first core 5 interlinks.

Abstract: A resin-coated aluminum alloy plate material good in flaw resistance, formability and/or workability, and printability, which comprises an aluminum alloy plate, whose Vickers hardness (Hv) is 30 or more, and an organic resin film having a thickness of 0.5 .mu.m or more, but 20 .mu.m or less, and containing a resin, whose glass transition temperature (Tg) is 10.degree. C. or less, and a wax and/or a fluororesin-series lubricant in an added amount of 1 to 30% by weight based on the solid content in the organic resin film, the organic resin film being coated on a surface of the aluminum alloy plate. The resin-coated aluminum alloy plate material has good flaw resistance, formability and/or workability, and printability, and can be preferably used as a shutter material of a recording medium cassette.

Abstract: A liquid-crystal polyester resin composition comprising 30 to 95 wt. % of a liquid-crystal polyester and 70 to 5 wt. % of an aluminum borate whisker.
