Abstract: PURPOSE:To improve the strength and weldability of a base metal and also the corrosion resistance of a composite material by heating an assembly slab at a temperature of >=1,050 deg.C, and thereafter, rolling it at a finish temperature of >=800 deg.C, and thereafter, bringing it water cooling to a temperature of <450 deg.C. CONSTITUTION:An assembly slab obtained by superposing a composite material consisting of stainless steel, and a base metal consisting of carbon steel or low alloy steel and welding its periphery is heated at a temperature of >=1,050 deg.C. In this way, a Cr carbide can be dissolved enough to stainless steel being the composite material. After this heating, said slab is rolled by setting a rolling finish temperature to >=800 deg.C. In this case, when a rolling reduction is performed in a temperature area of <800 deg.C, a corrosion resistance of stainless steel of the composite material is deteriorated. Immediately after rolling has been completed, the rolled assembly slab is brought to water cooling to a temperature of <450 deg.C. As for a stainless steel clad steel plate which has been obtained in this way, the strength of the base material rises greatly, and the weldability, especially, a characteristic of a low temperature crack resistance can be improved.

Abstract: PROBLEM TO BE SOLVED: To satisfactorily supply lubricating oil, and to prevent a ball from wearing and pitching, by forming an oil route through at least one of disk plates in parallel with an axis of the disk plate, in a device which is formed by arranging plural balls between a pair of disk plates. SOLUTION: When a differential case 1 is rotated by driving force transmitted from an engine, a ball holder 4 rotates integrally with the differential case 1, and this rotating force is transmitted to a groove 3b of each disk plate 3 through each ball 5, and to right and left driving shafts connected to each disk plated.

Filed: 1991-06-26
Abstract: PURPOSE:To enable a shortening of rising time of a heater to be realized without using any temperature sensor by a method wherein the rising state of the heater is judged in response to an electrical energization time for the heater and an elapsing time after stopping the operation of the heater and a cooling fan is operated. CONSTITUTION:A control means 103 drives a cooling fan in the case that an electrical energization for a resistance heating heater is continued for more than a specified electrical energization time or in the case that the electrical energization for the resistance heating heater is restarted before the specified stopping time elapses. Accordingly, when the heating is started, a cooling fan 104 is driven after a temperature of the heater is sufficiently increased and when the heating is restarted, the cooling fan 104 is driven before a temperature of the heater is not excessively decreased, so that a rising characteristic of temperature at the time of electrical energization of the heater is not influenced by a cooling action of the cooling fan 104. That is, in case it is judged that the heater is already risen, the cooling fan is rotated when the operation is started so as to prevent a temperature of the device from being increased and in turn when the temperature is lowered, the cooling fan is operated after a specified time from the starting of the electrical energization of the heater.
