Title: Applying method for lubricant for hot rolling tube
Inventor: NAKANISHI TETSUYA
IPC: B21B45/02
Filed: 1990-03-29
Abstract: PURPOSE:To prevent the stripping and falling-off lubricant in accordance with heating for rolling by removing a mill scale on the surface of a material to be rolled before the lubricant for hot rolling tube is applied on the surface of material to be rolled. CONSTITUTION:The lubricant for hot rolling tube which the base agent comprising essentially of metallic oxide is mixed with a binder is applyed on the surface of the material to be rolled. In such a case, the lubricant should be applied on the surface where the mill scale on the surface of the material to be rolled is removed. In this way, the surface roughness of the surface where lubricant is applied is good, adhesion when applying is excellent and also the oxidization itself of metallic part due to heating for rolling is restrained. Thus, in the case the material to be rolled is a plain steel or alloy steel which alloy components are more than a stainless steel, the falling-off of lubricant in accordance with stripping of scale is deterred and excellent lubricating effect is obtained because the sufficient quantity of lubricant for rolling is supplied.

Filed: 1995-03-16
Abstract: PURPOSE: To increase the speed of random read, and to prevent the generation of read disturbance by detecting the potential of first and second signal conductors connected to a memory cell unit and augmenting the quantity of a read signal. CONSTITUTION: A signal conductor 11 connected to a metal cell unit 30 is pre- charged to VA and a signal conductor 12 is to VB, and both signal conductors are floated. The signal conductor 11 is lowered by ΔVA from pre-charged potential VA and the signal conductor 12 is increased by ΔVB from pre-charged potential VB by the read operation of the metal cell unit 30. Since a sense amplifier 40 detects both potential changes ΔVA, ΔVB, the speed of random read can be accelerated by the augmentation of the quantity of a read signal. Since control voltage at the time of read is not built up, read disturbance is not generated either.
