A composite nickel plated sliding surface is obtained by the formation of a composite nickel plating film on a sliding surface of an automobile part such as an engine cylinder or piston by electroless nickel plating. The plating film contains at least one member of wear resistant particles having an average particle size of 0.1 to 1.0.mu. selected from SiC, TiC, WC, BC.sub.4, TiN, Al.sub.2 O.sub.3 or the like, and also at least one member of lubricating particles having an average particle size of 1 to 10.mu. selected from BN, MoS.sub.2, and Teflon. The nickel plating bath is adjusted to have a phosphorus concentration of 0.5 to 12%. When the matrix of the nickel plating film has a phosphorus concentration of 0.5 to 5%, the film hardness is improved.

摘要:
The present invention is made for the purpose of improving beef quality and upgrading its fat marbling standard (which is called beef marbling standard, or BMS). The fat marbling state is generally called “Shimofuri” in Japanese. This purpose is achieved by vitamin C administration (L-ascorbic acid) to the cattle. The vitamin C can be administered by injection etc., but the easiest way is by oral administration. When only the vitamin C is administered orally, however, it is decomposed by microorganisms in the rumen and the desired effect cannot be obtained. For that reason, the vitamin C needs to be coated with something so that it can be absorbed by the intestinal tract after passing through the stomach. Soybean-hydrogenated oil and fat is desirable for such covering material. An appropriate daily dose of the vitamin C is approximately 20 mg to 60 mg/kg of weight. According to the result of tests conducted on the Japanese Black Cattle, in terms of the yield, there is no significant difference between the cattle given the vitamin C and those not given it. In terms of the quality of the meat, however, there are significant differences in the fat marbling (Shimofuri), luster, firmness and texture of the meat.

An object of the present invention is to provide a walk assisting apparatus which enables persons having walking difficulties due to leg paralysis or other conditions to make the alternate walk improved for unassisted walking. The walk assisting apparatus according to the present invention comprises a left and a right full length leg brace swingably connected to left and right outer coxa links, an inner coxa link interconnecting the insides of the thighs of the left and the right leg supports, a swing center of the inner crotch link substantially coinciding with a swing center of the coxa links, so that the inner coxa link allows the leg supports to make the alternate walk properly.

A light pickup 4 is adapted to receive reflected light from a disc 1 and to input a signal into a determination means 12 while moving in the radial direction of the disc 1. The determination means 12 not only determines the current position of the light pickup but also calculates the time required for the light pickup 4 to move until reaching the signal-recording inner circular end of the disc, on the basis of the signal from the light pickup. The determination means 12 determines that no disc is set when there is no reflected light from the disc. The determination means 12 determines the size of the diameter of the disc 1 on the basis of the current position of the light pickup 4. The disc player has a structure in which it is not necessary to provide a switch for detecting the signal-recording inner circular end of the disc, a sensor for detecting the size of the diameter of the disc and a sensor for detecting whether or not the disc is set.

There is provided a structure of artificial bone for use in implanting or grafting bone comprising; a sintered body of calcium phosphate compounds; and hollowed minute tubes in said sintered body, having very small diameter, and extending along with a direction of Haversian canal extension of live organism, so as to produce two dimensional close-packed structure in said body, in form of cubic or hexagonal arrangement. The arrangement has in the sintered body of calcium phosphate compounds; hollowed minute tubes having a diameter of 0.1 to 2.0 mm, and the major portions thereof extending along with a direction of the Haversian canal extension, and producing a two dimensional close packed arrangement in said body against the face vertical to said direction, and being arranged with a separation, distance of 1.0 to 5.0 mm. The structure has preferably really spherical pores having diameter of 50 to 600 micrometer, and the porosity thereof being 0.5 to 40 percent.

A sintered alumina article having an excellent flexural strength comprises numerous sintered plate crystalline corundum particles each having cleavage surface planes and accumulated on and bonded to each other in a manner such that the cleavage surface planes of the accumulated plate crystalline particles are substantially in parallel to each other and can be produced by forming the plate crystalline corundum particles into a predetermined shape so that the plate crystalline particles are accumulated in the above-mentioned manner; and by sintering the resultant precursory article at 1500.degree. C. or more under the ambient atmospheric pressure.

摘要:
A system is disclosed for controlling the speed and torque of an electric motor throughout its entire operating range from low speed operation to high speed operation, while minimizing the total loss of energy in the motor. The minimization of energy loss is facilitated by controlling the motor field current during the low running speed of the motor as well as during the high running speed.
