Title: Heater device
Inventor: MIZUTANI YOICHI
IPC: B22D11/10
Filed: 1988-12-13
Abstract: PURPOSE:To restrain heat stagnation in inner part of an exothermic body by constituting a heater device of the exothermic body formed of an outer layer part having the necessary exothermic characteristic and an inner layer part having different exothermic characteristic with that of the outer layer part and an electrode part for conducting electric current to the exothermic body. CONSTITUTION:The outer layer part 20 is formed of the exothermic material and the blending ratio of magnesia and zirconia as main components is selected so as to become high resistant value. By this method, the heat generation becomes vigorous at the position coming into contact with the molten metal, and heating efficiency is improved. Further, as the inner layer part 25 is not brought into contact with molten metal, the exothermic characteristic thereof is not necessary so much as that of the outer layer part 20, or rather in order to restrain the heat stagnation in the inner part of the exothermic body 2, it is desirable to restrain the exothermic characteristic. Further, in the case of preheating, as the inner layer part 25 is not directly brought into contact with flame of a burner, the exothermic quantity may be not secured so much as the outer layer part 20 and further, plenty of consideration to erosion resistance and oxidizing resistance, etc., is unnecessary, and degree of freedom to selection of the blending ratio can be increased.

Title: Method for acceleration and deceleration control
Inventor: MISHINA KAZUHIRO
IPC: H02P29/00
Filed: 1993-12-15
Abstract: PURPOSE:To make excellent deceleration control possible by finding the quantity of decelerated movement by multiplying a unit movement quantity by a total control number, and determining a deceleration start point by subtracting the decelerated movement quantity from the total movement quantity up to a final arrival position. CONSTITUTION:How many control cycles an acceleration/deceleration time T corresponds to is found from the control cycles of an arithmetic processing circuit and a previously set acceleration/deceleration time T. Then a moving speed V is divided by an acceleration/deceleration unit to find a deceleration speed in synchronism with the control of the arithmetic processing circuit. This speed is called a speed increasing/reducing speed VD. Further, the moving speed V is divided by the speed increasing/reducing speed VD to find a speed increasing/reducing frequency. Then the number of boxes partitioned with longitudinal and lateral broken lines, i.e., the number of control boxes is found. The area of one control box indicates a movement quantity, so the speed increasing/reducing speed VD is multiplied by the control cycles to find the movement quantity. Then the unit movement quantity XU is multiplied by the number of control boxes to find the area of a part showing the deceleration period, i.e., the decelerated movement quantity X.

Title: Water supply apparatus
Inventor: NAKAMURA MAKOTO
IPC: C02F1/46
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To supply a desired amt. of effective chlorine-containing water according to a determined time and control the concn. of effective chlorine of a desired amt. of water obtained by water supply. SOLUTION: Since the emitting capacity of a pump is made variable corresponding to the water supply time and water supply quantity prescribed by a water supply command, a desired amt. of effective chlorine-containing water can be certainly supplied according to a determined time regardless of water supply quantity. Further, since the electrolytic current value applied to a pair of opposed electrode plates is variable so that effective chlorine is contained in a desired amt. of water obtained by water supply in desired concn., the concn. of effective chlorine in a desired amt. of water obtained by water supply can be accurately controlled.  Further, since tap water is electrolyzed on the way of water supply in the non-contact state with the open air within a hermetically closed electrolytic cell, formed effective chlorine can be effectively utilized to perform expected sterilization and the penetration of bacteria from the outside can be prevented to accurately avoid water pollution.
