    摘要： A composition of raw materials comprising silicon carbide, a substance containing at least one of Group IVa to VIa elements except any boride thereof, and a substance containing boron except any of the borides of Group IVa to VIa elements, and further containing, if required, carbon, or an organic compound which produces carbon as a result of thermal decomposition, or both, is fired to manufacture a silicon carbide-based material in which a boride of at least one of the elements of Groups IVa to VIa of the periodic table is dispersed. The silicon carbide-based material can be manufactured without using any of the borides of Group IVa to VIa elements as a starting material.

    摘要： A process for producing a metal boride sintered body having a density of at least 90% of the theoretical density and a raw material composition therefor. The raw material composition is composed of a metal oxide, a metal carbide, and boron carbide, the amount of boron carbide being 5 to 20% more than the amount stoichiometrically required to form a metal boride by reaction of boron in the boron carbide with the metal element(s) in the metal oxide and metal carbide. By using this composition, it is possible to produce a metal boride sintered body having high density and high hardness without adding a sintering auxiliary or carbon and using a very high pressure.

    摘要： Air-accumulating chamber of a roof air duct has a non-branched configuration and is located substantially centrally in a widthwise direction of a vehicle. Air emission port sections emit conditioned air from the air-accumulating chamber toward respective rear seats. In each of the air emission port sections, a sawtooth-like surface is formed on each port base member and a resilient locking protrusion is provided on a grill for meshing engagement with the sawtooth-like surface. Air emission port, air-conditioner operating section and room lamp are provided together as a unit on the port base member.

    摘要： A crystal-oriented ceramic has an isotropic or pseudoisotropic perovskite-type-structure of not smaller than 10% in Lotgering orientation degree. The ceramic may contain at least one of Bi, Sr and Ca. A host material, a raw material capable of producing a guest material and an additive having the ability of converting a host material into a guest material are mixed and roll-pressed, and sintered under heat to give the crystal-oriented ceramic as a large-sized and bulky material. This crystal-oriented ceramic has good crystal orientation-dependent characteristics including piezoelectricity, pyroelectricity, ionic conductivity, giant magneto-resistivity effect, etc. This crystal-oriented ceramic can be produced by orienting epitaxially the polycrystals of an isotropic or pseudoisotropic perovskite oxide according to the orientation of the crystal plane or axis of a host material. The ceramic can be applied to an inexpensive and large-sized device. The host material may be a magnetoplumbite-type-structured or Sr.sub.2 Nb.sub.2 O.sub.7 -type-structured material, and may be composed of morphologically-anisotropic grains.
