Abstract: PURPOSE: To improve the reproduction of a hue fixed in a 1st base system for a television(TV) image observer. CONSTITUTION: In the TV projection method for generating the color image dots 74 of a TV image irradiated with optical signals RL', GL', BL' having respectively different wavelengths, transformation from a 1st base system to a 2nd base system is validated by a matrix expression. The shortest wavelength of the optical signals RL', GL', BL' is <=470 nm. The wavelengths of the optical signals RL', GL', BL' are determined so as to include at least the vertex of a hue range 440 of the 1st base system having wavelength larger than the shortest wavelength determined by a screen phospher. All hues generated by the transformation of the matrix array in the common range of hues in the 2nd base system are the same as hues determined by a chrominance signal in the 1st base system.

Abstract: PURPOSE:To obtain a steel bar having high ductility equivalent to the ductility of a softened stock by rolling a steel billet with a specific composition while controlling the temp. in the course from roughing to finish rolling, subjecting the rolled stock to quenching in which surface temp. is specified, and then recuperating the surface temp. CONSTITUTION:A billet of a steel having a composition consisting of, by weight, 0.10-0.60% C, <=0.35% Si, 0.30-1.70% Mn, 0.0040-0.0200% N, further 0.010-0.100% of one or more elements among Ti, Zr, Nb, and Al, and the balance Fe with inevitable impurities is heated up to 850-1000 deg.C and hot-rolled. At this time, the temp. of the steel in the course from an intermediate mill group to the inlet side of a finishing mill group is regulated to 600-750 deg.C. The temp. in the course from roughing to the conclusion of finish rolling is also regulated to 700-850 deg.C. Further, after finish rolling, the surface temp. of the steel stock is quenched down to 500-680 deg.C by means of water quenching and then the surface temp. is recuperated by means of the internally retained heat of the steel stock, followed by slow cooling. By this method, the bar steel with high ductility improved in the value of reduction of area can be obtained.

Title: Roll grinding control method and device thereof
Inventor: TANIMOTO TATEO
IPC: B24B49/00
Filed: 1986-02-19
Abstract: PURPOSE:To make a roll grindable with the desired accuracy even during strip rolling, by grinding it after controlling stock removal per unit time in the roll to be constant, and finishing the grinding at that point that time from a grinding start accords with the time required for securing the specified stock removal. CONSTITUTION:Peripheral velocity of a roll 2 during grinding operations, for example, a rolling speed is detected and calculated, and on the basis of this operation value, pressing force of a grinding wheel 1 to the roll 2 is controlled by a pressure control mechanism 9 so as to give an inversely proportional relationship to an interval between stock removal per rotation in the roll 2 and the roll peripheral velocity. With this relationship, roll grinding is carried out so as to cause the stock removal per unit time in the roll 2 to become constant. And, the pressure control mechanism 9 releases the pressing force of the grinding wheel 1 by a hydraulic cylinder 5 at a time when time from a grinding start by a pressure detecting mechanism 8 accords with the time required for securing the specified stock removal, thus grinding is over. Therefore, high processing control is no longer required, and even in such an on-line that speed varies, the roll is grindable so accurately.
