    摘要: An earthquake-proof leg support structure (10) of an electronic apparatus comprising a leg (12) vertically downwardly extending from the outer case (1) and a dish-shaped leg support seat (20) to receive the leg (12). The leg support seat (20) includes a metal element (28) having an upper surface (22) over which the leg (12) slides and a peripheral flange (24) against which the leg (12) abuts, and a plastic liner (30) having a lower flat smooth surface (26) which is slidable on the floor. The lower end surface (14) of the leg is of a convex spherical shape and the upper surface (22) of the leg support seat includes a central surface portion (22a) of a concave spherical shape and a cone-shaped slope portion (22b) arranged around and tangential to the central surface portion, with the radius of curvature of the leg (12) being smaller than that of the upper surface (22) of the leg support seat (20 ).

    摘要: A method for sheet forming a remarkably waterproof gypsum hardened body, in which a main component consisting of gypsum dihydrate, slag and calcium hydroxide and additives are added with a part of the main component coated with a hydrophobic diorganopolysiloxane fluid having a kinetic viscosity of 10-10,000 CS at 25.degree. to be sheet formed and cured. The hydrophobic diorganopolysiloxane fluid is uniformly dispersed through the sheet formed gypsum hardened body and its strong water repelling property makes the gypsum hardened body remarkably waterproof to be used suitably as both interior and outdoor construction materials.

    摘要: A process for producing a fiber-reinforced hardened body comprising mixing gypsum and slag in a ratio by weight of the former to the latter between 3:7 and 7:3 to prepare a main starting material, adding to the main starting material 1 - 30% by weight of reinforcing fiber, 0.1 - 5% by weight of alkali salt substance and 0.1 - 5% by weight of aluminum sulfate-containing substance, the respective amounts being based on the weight of the main starting material, further adding water to knead and mold the resulting starting material mixture, and curing the molded starting material mixture under normal condition or steam-curing the molded starting material mixture at 90.degree. C. or below.
