IPC: F02M61/18
Filed: 1990-07-24
Abstract: PURPOSE:To lock a pipe to a nozzle body surely and firmly by solidifying a part of the nozzle body heated and molten and joining the nozzle body and the pipe together. CONSTITUTION:A ceramic pipe 3, having a smaller outer diameter than a diameter of a hole 4 formed in a nozzle body 1 and also having a thermal expansion coefficient equal to that of the nozzle body 1, is inserted into the hole 4. Next, only the neighboring nozzle body 1 adjacent to this pipe 3 is locally heated and melted, then a part of the heated and melted nozzle body 1 is solidified and the nozzle body 1 and the pipe 3 are joined together. With this constitution, the pipe 3 is not bitten into the nozzle body 1, while the pipe 3 is not damaged by a thermal shock, thus the pipe 3 is locked surely and firmly and, what is more, such a phenomenon that the pipe 3 is separated from the nozzle body 1 by spouting pressure at time of use is not produced at all.

Abstract: PURPOSE:To stabilize the reduction rate of rolling load and to extend the lives of a roll and a draining wiper by adjusting the pressing pressure of a draining wiper to fix the deposition efficiency of lubricant to be supplied on the surface of the roll. CONSTITUTION:In a work roll 1, a backup roll 2, a draining wiper 3, an air cylinder 3a to adjust the pressing pressure at the contact part with a roll is arranged at the rear end of this wiper 3. An arithmetic unit 5 operates the reduction rate of a rolling load by a load signal from a load cell 4 to determine the pressing pressure P of the draining wiper 3 so that a prescribed reduction rate is obtained. The cylinder 3a of the draining wiper 3 is actuated by a pressure controlling mechanism 6 in accordance with determined pressing pressure to supply lubricant through a header 7 for the work roll coolant, a header 8 for supplying lubricant. In this way, though wear of the wiper 3 advances, the deposition efficiency of the lubricant at the work roll 1 becomes fixed and the reduction efficiency of rolling load by the supply of the lubricant, is stabilized as well.

Abstract: PURPOSE:To protect an output use transistor at a high speed, and also, with high accuracy by setting the output use transistor to a non-conducting state, when a current flowing to the second emitter electrode has exceeded a prescribed value. CONSTITUTION:By heating of an output use transistor 5 which has become an overload state, a base - emitter voltage VBE of the output use transistor 5 drops because it has a negative temperature characteristic, a current mirror ratio of the output use transistor 5 and a control use transistor 8 is shifted, and as for an emitter current, the second emitter current of the output use transistor 5 flows in large quantities, and the emitter current of the control use transistor 8 decreases. As a result, when a collector current becomes below a prescribed value, a control part 9 varies and output point 9b from a 'H' level to an 'L' level, and the output use and control use transistors 5, 8 becomes a non-conducting state.
