CONSTITUTION:In case there is a big difference of coefficients of thermal expansion between  a magnetic core material and a nonmagnetic ceramic material, a magnetic core 1 is divided  into two parts. These two parts are then unified, and a winding 5 is applied at the center arm part. At the same time, a taper expanding at its lower part is applied lengthwise to the  outer face of the core 1. The core is enclosed by the nonmagnetic ceramic members 3, 4, 6  and 6' at the front and back sides in the longer direction of the core 1 and from four directions at both sides of the shorter direction. Then the core is pressed from a direction 10 and  positioned to be fixed temporarily with an organic adhesive. The faces of the members 3 and 4 which are shown by oblique lines in figure, their opposite faces and the members 6 and 6'  are adhered together by means of glass, etc. at a high temperature. In this case, the organic  adhesive sublimes. The face containing a gap 2 and its opposite face join the core to a magnetic head holding stand. Thus an assembly is possible with high precision and without adhering the core member to the members 3, 4, 6 and 6'. As a result, the deterioration is prevented for the electromagnetic converting characteristics.

Abstract: PURPOSE:To obtain the product excellent in property, injecting always the constant amount of molten resin into the cavity of a mold by a method in which even if the close timing of the check ring for preventing the back flow of the molten resin is fluctuated, it is automatically corrected. CONSTITUTION:After plasticizing measurement has been finished, the pressure in the pressure chamber 16 of a cylinder which is lower than the injection pressure of molten resin into a cavity is kept for a constant time or during the time until said pressure rises to a constant pressure, and preliminary injection is carried out, thereby retracting a check ring 23 and placing it at a back flow preventing position. The screw position at the time of the preliminary injection- finish is memorized, and the screw 12 is controlled to advance from this position by a specified distance. Consequently, because the back flow has been prevented by the check ring at the time of the screw advance, the volume by the screw advance is same as the injection amount of molten resin into the cavity. Therefore, every shot injects the same amount of the resin.
