Title: Continuous casting method by electron beam melting method
Inventor: SODO TATSUHIKO
IPC: B22D11/041
Filed: 1985-11-29
Abstract: PURPOSE:To improve cooling efficiency and productivity by disposing solid members for cooling an ingot in an ingot making chamber existing below a water-cooled cating mold and bringing the members into force contact with the solidified ingot thereby cooling the ingot. CONSTITUTION:A pair of the cooling members 8 are disposed to the boundary part wall 7a between the electron beam melting chamber 1 and the ingot making chamber 7. The members 8 are piston-like members of which the top end faces are formed of copper plates. The rod parts 8a thereof are freely slidably supported by the wall 7a. Vacuum seals are provided to the sliding parts. The members 8 are internally constructed to allow circulation of cooling water. The cooling water is connected through the inside of the rod part 8 to an outside supply source. The cooling power is thus increased without hindering the continuous casting by electron beam melting, by which the melting speed is increased.

Abstract: PROBLEM TO BE SOLVED: To find the inverse tangential arithmetic result corresponding to the input signal of multiple bits without using a high capacity ROM by applying a phase rotation to the inverse tangential arithmetic result of an inverse tangential approximate arithmetic circuit and outputting the inverse tangential arithmetic result in the original quadrant of a complex signal.

Title: Absorption refrigerator
Inventor: KANEKO TOSHIYUKI
IPC: F25B15/00
Filed: 1987-10-27
Abstract: PURPOSE: To prevent counter flow of a refrigerant liquid to a condenser by providing an overflow pipe for introducing the refrigerant liquid from the refrigerant liquid flow-down piping between the condenser and the pump delivery side of the refrigerant liquid circulation pump of an evaporator to the evaporator. CONSTITUTION: When the pressure difference between a condenser 3 and an evaporator 4 is extremely lower or higher than the delivery pressure of a refrigerant liquid pump PR at the time of starting, for example, liquid level in piping 10 increases to reach the opening O of a container A. The refrigerant liquid flows dyer the opening O and returns through piping T back to the refrigerant liquid reservoir of the evaporator 4. Consequently, cavitation of the pump PR and counter flow of nonvaporized refrigerant from the evaporator 4 to the condenser 3 is prevented and operation can be sustained stably while preventing the condenser from being filled with the refrigerant liquid to damage the function thereof significantly.  Since the refrigerant liquid flowing through the piping T into the evaporator 4 has a temperature level similar to that of the nonvaporized refrigerant, flash evaporation in the evaporator 4 is prevented and heat loss is substantially eliminated.
