Abstract: PROBLEM TO BE SOLVED: To remarkably reduce manufacturing cost and maintenance/ management cost without using a 4-high roughing mill having complicated structure by using lubricating oil for lubrication of a rolling part, using a 2-high roughing mill and making a slab into a sheet bar by executing hot rough rolling. SOLUTION: The slab 50 having the thickness of <=150mm and width of <=2300mm is hot rough rolled and made into the sheet bar 50a. The lubricating oil 11 is used for lubricating the rolling part. The coefficient of friction of the lubricating oil 11 is about μ=0.2 or smaller, as compared with the coefficient of friction of water lubrication of μ=0.3, so rolling load is reduced and rolling with the 2-high rolling millis enabled. As compared with the 4-high rolling mill, in the 2-high rolling mill 10, the diameter of the work roll 1 is approximately same and a small size. When the slab 50 is simultaneously hot-rolled with two 2-high rolling mills which are closely arranged, the slab is made into the sheet bar 50a having small camber.  A continuous casting equipment for thin slabs is developed and casting technique is progressed, so the slab whose thickness is <=150mm is manufacturable by continuous casting.

Title: Temperature detecting circuit
Inventor: NOMURA YASUHISA
IPC: G01K7/24
Filed: 1991-09-27
Abstract: PURPOSE:To detect temperature accurately regardless of stray capacitance by connecting in parallel the base and emitter to the resister of both transistors of PNP type and NPN type, and connecting the inside conductor of heat sensing wire to both base sides and an alternating current power source to both emitter sides. CONSTITUTION:The inside conductor 13 of a heat sensing wire 1 is commonly connected to the base of both transistors T1 and T2 of PNP type and NPN type and one side of an alternating current power source 7 is impressed. The other side of the power source 7 is commonly impressed to the outside conductor 11 of the heat sensing wire 1 and the collector side of transistors T1 and T2 by way of diodes D1 and D2 and resister R3 and R4. Thus, all the induction current incurred by the stray capacitance C received by the heat sensing wire 1 is relieved to the other side of the power source 7 through the conductor 11. As the operation of the transistors T1 and T2 is not affected by the induction current, zero point detection of the alternating current voltage and current wave forms is exactly done. By measuring the voltage impressed to the heat sensing wire 1 and the phase angle of the current on it, temperature signal of the heat sensing wire 1 can be obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent a short circuit of adjacent electrodes in a process of printing the electrodes around through holes, by making the thickness of a ceramic base, the diameter of the through hole, the length of a short side after division and the pitch of the through holes satisfy specific conditions. SOLUTION: A ceramic base 10 is provided with longitudinal and lateral division grooves 11 on the surface, and through holes 12 are formed in these division grooves 11. When the thickness of the ceramic base 10 is made (t), the diameter of the through hole 12ϕ, the length of a short side of a base body 13 after division (c) and the pitch of the through holes 12 (p), conditions c<=1.0mm and p<=0.5mm are satisfied. This means that a resistor is small-sized. By satisfying ϕ/c <=0.19, moreover, the diameter ϕ of the through hole 12 is lessened, while a space between the through holes 12 is widened, and thereby a short circuit at the time of formation of electrodes 21 is prevented. By satisfying t/c >=0.32, besides, the thickness (t) is enlarged and thereby impairment of the resistor at the time of packaging can be prevented.
