    摘要: A process for ion nitriding aluminum or an aluminum alloy as an article to be treated, in which: the article is disposed in a sealed vessel; the oxygen gas in the vessel is removed; the surface of the article is heated to a prescribed nitriding temperature; the surface of the article is activated to facilitate the formation of an aluminum nitride layer by the subsequent nitriding treatment; and thereafter the article is subjected to ion nitriding, thereby forming an aluminum nitride layer having excellent wear resistance and high hardness. This ion nitriding treatment for aluminum material can be carried out even at temperatures lower than a solution treatment temperature of aluminum material.

    摘要: A method and treating material are presented for forming a mixed-carbide layer of at least one Va-Group element and of chromium on the surface of a carbon-containing ferrous-alloy material. A molten treating bath is prepared by introducing one or more Va-Group elements in oxide form and chromium in metal or alloy form or by introducing one or more Va-Group elements in metal or alloy form and at least one chromium oxide into a molten bath composed of boric acid, of at least one borate or of a mixture thereof. An article of carbon-containing ferrous alloy is immersed and maintained in the molten treating bath until a mixed-carbide layer is formed on its surface. The mixed-carbide layer formed on the surface of the article is very smooth, wear resistant and high-temperature-oxidation resistant.

    摘要: In a control apparatus for a hydraulically operated vehicular transmission having a plurality of speed stages to be established by a selecting operation of a plurality of hydraulic clutches, when a command to downshift to G(N-2) is issued in the course of downshifting to G(N-1) and a flag FTBD is set to 1, a control is performed to accelerate the time of completion of the downshifting control to G(N-1). When that oil temperature in the transmission which is detected by an oil temperature sensor is lower than a predetermined value, the setting of FTBD to 1 is prohibited. Therefore, at the time of low oil temperature, the downshifting to G(N-1) is performed in an ordinary manner. At the time of starting of the downshifting control from G(N-1) to G(N-2), the hydraulic pressure in the hydraulic clutch for the speed stage G(N-1) is sufficiently increased. A smooth downshifting to G(N-2) can thus be smoothly performed without the occurrence of excessive engine racing.
