摘要： Particles such as magnetic iron oxide capable of being magnetized are crushed to obtain minute magnetic particles each size of which is not larger than 10 .mu.m. The minute magnetic particles are mixed as they are dispersed with such a binding material as cobalt or nickel. Thermal spraying particles each size of which is not smaller than 10 .mu.m are obtained from the mixture. Then, the thermal spraying particles are sprayed upon such a member as a turbine shaft to form a magnetic film on the member with plasma spraying method.

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 process for forming a sintered layer on a substrate of an iron-based material containing carbon. A sheet of powders of an alloy is prepared by mixing the powders with a solution of resin and rolling the mixture into a sheet. The sheet is then heated to a sintering temperature. In order to prevent carbon content in the substrate from diffusing to the powder sheet during the sintering process, a lamina is provided beneath the powder sheet for example by a metal plating, a metal oxide layer, an intermediate alloy powder sheet, a decarbonized layer.

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.
