Abstract: A metal die device for casting of a simpler device structure by which a cast product having an undercut may directly be produced is disclosed. A casting (cavity) S is provided between a fixed die 21 and a movable die 31 as a movable core 40 having an undercut forming projection 41 is interposed between the fixed and movable dies. A swing member 54, caused to swing by a cylinder 51, is provided overlying the movable die 31. On the swing member 54, there is provided a cylinder 57 for vertically sliding the core 40. In die opening, following casting, the core 40 is vertically slid and subsequently caused to swing towards an upper outer side to release the core 40 from the cast product. Degree of freedom in metal designing is achieved without excess restriction in the shape or position of the undercut.

Abstract: Liquefied product can pass through a sterilizing apparatus at high temperature and in a short time with high efficiency of heat transfer so that sterilizing effect can be enhanced, loss of fragrant component is prevented, and at the same time fats and fibers of raw materials are homogenized. A sterilizing apparatus including heating element 16 and a cooling element concentrically including a pair of heat transfer discs having a plurality of polygonal small chambers thereon which are open at fronts thereof, in each pair the heat transfer discs being coupled to each other face to face, wherein the small chambers are alternately arranged with one another so as to communicate with one another.

Abstract: A heat exchanger for enhancing thermal efficiency between two fluids and lengthening a fluid passage so as to increase contact surfaces between heat exchanger and fluids and permitting the heat exchanger to be compact as a whole. The heat exchanger includes a combination of first and second heat exchanger units respectively comprising larger and smaller diameter discs on which small chambers, which are open at fronts thereof and communicate with one another, are provided, so as to permit the fluids to perform striking, dispersing and meandering operations.

Abstract: A stationary type mixing apparatus capable of mixing fluids having high viscosity and improving mixing efficiency of plural kinds of fluids.
