Title: Hot rolling method for steel
Inventor: IZAWA MASARU
IPC: C23C22/46
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To improve a surface property of a steel as well as descaling ability by forming an oxalate film of alkaline earth metal on a steel surface, heating and hot-rolling. SOLUTION: By spraying an oxalate aq. solution of oxalic calcium, oxalic potassium, oxalic ammonium, etc., on a steel surface and brush coating or immersing the steel in the solution, an oxalate film is formed on a steel surface. A concentration of oxalic calcium in an aq. solution is desirably 5-30%. Oxalic calcium of 20-1,000 g/m<2> is desirably stuck on a steel surface. An oxalic calcium aq. solution evaporates its water content by heating to superfine particles. The oxalic calcium is heated at high temp. to calcium carbonate to effectively act as a solid lubricant. Part of the calcium carbonate is turned to calcium oxide to react with scale and to generate calcium iron oxide. Descaling ability after rolling is greatly improved.

IPC: G11B7/085
Filed: 1988-12-19
Abstract: PURPOSE:To control the vibration of an objective lens by detecting deflection information of a fine actuator from a signal when a dividing-detector detecting a tracking error has detected a mirror surface and feeding back deflection information to the driving circuit of the dense actuator in the middle of a seeking action. CONSTITUTION:When an optical head seeks an objective track, the two-dividing detector 10E detects the deflection of the fine actuator 11 from the reflected light of the mirror surface in an optical disk and feeds back the position signal in the middle of seeking. Then, the seeking action is stably performed, the signal of a low frequency component, which is detected from the reflected light obtained from the mirror surface, is supplied to a coarse actuator 10, and the optical axis of the two-dividing detector 10E is always caused to agree with the optical axis of the objective lens 11A. Thus, the vibration of the objective lens 11A can be controlled when a seeking speed is lowered near the objective track since the two-dividing detector 10E always detects the reflected light of the mirror surface, and deflection information of the objective lens 11A is detected.

Title: Motor controller
Inventor: CHIKADA SHINICHI
IPC: H02P7/29
Filed: 1991-11-08
Abstract: PURPOSE:To perform a constant-speed control of a variable target speed and to effectively and rapidly interrupt power supply at the time of locking by so controlling to negatively feed back a PWM modulation factor that a deviation between an actual rotting speed and a target rotating speed becomes zero. CONSTITUTION:A transistor 7 is turned ON, OFF by a PWM signal V6, a PWM voltage is applied to a battery 10 or a DC motor 8, which starts to be rotated. The PWM voltage rises in proportion to the rise of a modulation factor control signal V4. Then, a mean voltage V1 to be output from a differential integrator 11 also rises in proportion to the rise of the signal V4. Since the voltage V1 is fed back to a b terminal of a deviation integrator 5, a deviation input of the integrator 5 is reduced, and the rising of the voltage V1 to be output from the integrator 11 is smoothed. A difference between a command voltage V0 and the fed-back mean output V1 becomes zero, an increase in the voltage V4 is stopped, and it is stabilized at a predetermined level necessary to obtain a desired speed.
