Abstract: A cast product for an automatic transmission includes a body portion; and a projecting portion that projects from the body portion. A wall surface of the projecting portion is connected and integratedly cast with the body portion by a plurality of ribs. Among the plurality of ribs, at least one rib is integratedly joined on one side thereof with the projecting portion along the wall surface of a side edge portion of the projecting portion, while another side of the at least one rib is integratedly joined with the body portion.

Abstract: A transmission case includes a power transmission mechanism; a first case body and an adapter portion. The adapter portion includes a boss portion through which the output shaft is inserted, a first concave portion provided on an outer peripheral side of the boss portion and open rearward in the shaft direction, which is on the power output side of the power transmission mechanism, and a second concave portion open outward in a radial direction of the boss portion with the second concave portion separated in the shaft direction from the first concave portion by a separating wall.

Abstract: A powder of solid and spherical glass particles is easily manufactured by subjecting a mixed solution of a raw material oxide powder comprising a glass network-forming element, and an aqueous solution of a water-soluble compound comprising a glass-forming element other than the element of the raw material oxide powder to spray-thermal decomposition, wherein the spray-thermal decomposition temperature is set to be in a specific range according to the amount of the raw material oxide powder in the total of the amount of the raw material oxide powder and the oxide-converted amount of the water-soluble compound, as well as the average particle size of the glass powder to be manufactured.

Abstract: A separable tow of elongated polymeric filaments comprises a plurality of distinct sub-tows lightly and individually and separably joined, as by light crimping together along their edges or, if uncrimped, joined by presence of moisture, and capable of being packed into a container and later removed and separated. The filaments are preferably acrylic and have a total fineness of about 300,00-1,500,000 denier and the sub-tows each of which has a total fineness of about 50,000-250,000 denier, with a filament fineness of about 1-2 denier, and each sub-tow has a degree of entanglement of about 10-40 m−1 as measured by the hook drop test. The separable tow is made of a plurality of sub-tows, after separately drawing the sub-tows and subsequently removably joining the sub-tows into a single tow.

Abstract: An oxide having a perovskite structure, for example, barium titanate, is provided in which the particle diameter is as small as about 0.03 to 0.2 &mgr;m, the amount of OH groups in the crystal lattice is less than about 0.2% by weight, the c/a axial ratio is as large as about 1.0033 or more and sufficient ferroelectricity is exhibited. Barium titanate is produced with steps of mixing a BaCO3 powder and a TiO2 powder having a specific surface area of about 10 m2/g or more and heat-treating the mixed powder. In the heat treatment, in the case in which a partial pressure of oxygen is decreased to about 2×103 Pa or less and more than about 2×102 Pa, the heat treatment is performed at a temperature within the range of about 700 to 1100° C., and in the case in which a partial pressure of oxygen is decreased to about 2×102 Pa or less, the heat treatment is performed at a temperature within the range of about 600 to 1100° C.

Abstract: Applying a sizing agent as a water dispersed sizing agent to a continuous carbon fiber bundle consisting of 20,000 to 150,000 filaments, controlling the packing density in a range of 5,000 to 20,000 D/mm, cutting the carbon fiber bundle in a wet state of 10 to 35 wt % in solution content at the time of cutting, and drying with vibration at a solution content of 15 to 45 wt % before drying.
