    摘要： In order to superimpose and store optical fiber ribbons in a corresponding one of spiral grooves provided in the outer circumferential surface of a spacer, an optical fiber ribbon stranding device includes: a device for advancing the spacer straight while rotating the spacer around the center axis of the spacer, the advancing device being constituted by, for example, a tension giving device and a take-up device; a device for feeding a plurality of optical fiber ribbons; a guide die for guiding the optical fiber ribbons into the corresponding one of the spiral grooves; and an alignment keeping guide disposed upstream of the guide die. A rectangular hole is provided to extend through the alignment keeping guide, and the optical fiber ribbons are passed through and superimposed by the hole. The optical fiber ribbons kept in a superimposed state by the alignment keeping guide is introduced and accommodated into the corresponding one of the grooves of the spacer through the guide die.

    摘要： An electrical device cabinet includes a cabinet body, a front panel, and a positioning mechanism. The cabinet body has an open front end. The front panel is formed by a resin molding, and is mounted to the front end of the cabinet body. The positioning mechanism includes a concave portion disposed at the cabinet body and a convex portion disposed at an inner face of the front panel. The positioning mechanism positions the front panel in a lateral direction with respect to the cabinet body by mating the concave portion and the convex portion. The convex portion is formed in a hollow shape and is covered by an outer face of the front panel from a front side of the front panel.

    摘要： A method for manufacture of a high toughness sintered body, characterized by sintering a shaped body of a mixed powder consisting essentially of from 40 to 70% by weight of a first component of powdered ZrO.sub.2 containing at least one stabilizer selected from the group consisting of Y.sub.2 O.sub.3, CaO, and MgO and having an average particle diameter of not more than 1.mu. and from 30 to 60% by weight of a second component of powdered .alpha.-Al.sub.2 O.sub.3 having an average particle diameter of not more than 1 .mu.m, which mixed powder may also contain not more than 3% by weight of SiO.sub.2, not more than 0.5% by weight of Fe.sub.2 O.sub.3, or not more than 0.5% by weight of TiO.sub.2 in a combined proportion of not more than 3% by weight at a temperature in the range of from 1400.degree. C. to 1600.degree. C. under normal pressure thereby producing a sintered body wherein at least 90% by weight of ZrO.sub.2 particles present therein are accounted for by tetragonal and cubic crystals, the ratio of said tetragonal crystals to said cubic crystals is at least 1:3, and the average crystal particle diameter of the entire sintered body is at least 3.mu..
