    摘要： A heliostat capable of collecting light with high efficiency and having reduced manufacturing and installation costs; and a method of controlling the heliostat. The heliostat includes a reflecting mirror configured to reflect sunlight; and a support mechanism configured to tiltably support the reflecting mirror. The support mechanism has a single supporting column and first and second cylinders. The reflecting mirror is supported at its back surface by a supporting column upper end of the supporting column, a first cylinder upper end of the first cylinder and a second cylinder upper end of the second cylinder in a tiltable manner, which are arranged to form a triangle on the back surface of the reflecting mirror. A gimbal bearing connects the supporting column upper end and the reflecting mirror, the gimbal bearing being configured to be tiltable in two axial directions intersecting with each other.

    摘要： A copper-based alloy includes one base phase selected from the group consisting of &agr; phase, &agr;+&bgr; phase, and &agr;+&bgr;+&ggr; phase, a component having a lower melting point than the base phase, and a component for dispersing the base phase and the low melting component to uniformly disperse the low melting component and improve the copper-based alloy in machinability. A method for producing the copper alloy in the form of a bar or plate includes the steps of compounding raw materials in predetermined ratios thereby obtaining a mixture, fusing the mixture thereby obtaining a melt, continuously casting the melt into a cast billet, or rolling the cast billet thereby obtaining a shaped mass, heat-treating the shaped mass, drawing or rolling the heat-treated shaped mass thereby obtaining a plastic mass, and subjecting the plastic mass to a heat-treatment of air cooling or furnace cooling.

    摘要： A low alloy sintered steel contains at least 0.15 percent by weight and less than 0.8 percent by weight of carbon. Its matrix is formed by a tempered martensite containing prior austenite crystal grains of not more than 15 .mu.m in mean grain size. Pores and nonmetallic inclusions contained in the matrix are not more than 50 .mu.m in maximum diameter, and the density of the low alloy sintered steel is at least 96 percent of theoretical density. A raw material powder for forming the low alloy sintered steel includes iron alloy powder which is prepared by an atomizing process, and is treated with a dry mill in an inert gas atmosphere or in the atmospheric air. Thus, dislocations are introduced into the raw material powder, and nonmetallic inclusions contained in the raw material powder are pulverized to be not more than 50 .mu.m in maximum diameter. Not only static characteristics but also dynamic characteristics, such as fatigue strength, of the low alloy sintered steel are improved.
