Abstract: A thermoelectric water chiller system for cooling fluids, and including a cold sink which defines quiescent areas where convection currents are minimized to facilitate ice formation around the cold sink is provided. The cold sink cooperates with water held in a sealed tank. A cover member which covers the cold sink can be employed which would cooperate with the tank to form a fluid-tight seal therewith. Components needing periodic cleaning are preferably removable from the system, but the tank could be permanently installed. A fan-cooled thermoelectric module assembly is used to form the ice block adjacent the bottom of the tank which chills the water. A variable-speed fan and current to the thermoelectric module are controlled by a control circuit with inputs from various temperature sensors positioned on and within various portions of the chiller system, including sensors to monitor ambient air temperature about the chiller system.

Abstract: A method for controlling the injection of a die casting machine in which immediately after molten metal is injected into a cavity of metal molds at a high speed, the pressure oil in the chamber at the rod side of an injection cylinder is discharged into a tank side to commence the increase in pressure. A reference point for a switching-over position where a high speed charge is switched over to the increase in pressure is determined by computing a necessary length along the path for keeping the increased charging pressure on the basis of the supplied molten metal quantity during the previous injection process and subtracting the length from the length between the starting position and the position of limit of the forward movement at the previous injection process.
