    摘要: A pair of magnetic recording parts are axially spaced on a rotating shaft and a pair of magnetic heads for recording and reproducing a location signal are respectively opposed to the respective magnetic recording parts. Torque of the rotating shaft is calculated based on a quantity of a phase shift of the location signals reproduced by the respective magnetic heads and rotating speed of the rotating shaft is calculated based on a reproducing frequency of the location signal reproduced by one of the magnetic heads so that the magnetic recording parts and the magnetic heads serves as a sensor for detecting both torque and rotating speed. Thus, a number of parts of the sensor is lessened, being compacted with low cost.

    摘要: A process of forming a high alloy layer on a surface of an aluminum alloy casting. The process comprises steps of providing a mixture of fine powders having an average powder size finer than 10 microns, preferably finer than 1.0 micron, of an alloying metal or an alloying alloy and an acrylic binder, shaping the mixture into a sheet, heat treating the sheet at 150.degree. to 380.degree. C. for more than 5 minutes, placing the heat treated sheet on a surface of a casting mould or a chilling block, and casting molten aluminum alloy.

    摘要: Powder which has primary particle size of not larger than 10 .mu.m and is formed of mixture of Ni powder and Cr powder added with hard particles containing carbide is mixed with Cr.sub.3 C.sub.2 powder and granulated and sintered, whereby flame spraying powder having secondary particle size of 5 to 53 .mu.m is formed. The flame spraying powder thus formed is flame-sprayed under conditions which will cause fused Ni.Cr to cover Cr.sub.3 C.sub.2 particles which are not fused, thereby binding the Cr.sub.3 C.sub.2 particles and causes the thickness of one Ni.Cr layer to be smaller than 5 .mu.m. In this manner, flame spray coating the porosity of which is not larger than 2% and the hardness of which is not lower than 700 (Hv: 200 g) can be obtained.

    摘要: A method for sealing porous metals, which comprises applying powder of a eutectic alloy containing an element having a good diffusibility in a porous metal or powder of a mixture of metals capable of forming the eutectic alloy, to the surface of a porous metal member and heating the surface applied with the powder at a temperature higher than the eutectic temperature of the eutectic alloy to thereby cause the molten eutectic alloy to intrude into pores from the surface of the porous metal member, whereby the melting point of the molten alloy in the pores is promptly increased by diffusion of the element in the porous metal member to solidify the molten metal in the pores, sealing only pores present in the vicinity of the surface of the porous metal member.
