Title: Magnetic head
Inventor: KUROSAWA MAKOTO
IPC: G11B5/105
Filed: 1981-10-02
Abstract: PURPOSE:To ensure the perfect sealing and to improve the electric characteristics, by using the resin which has a small forming shrinkage factor, a small water absorbing factor and a low forming temperature to seal a magnetic head material body into a shielding case. CONSTITUTION:A magnetic head material body 7 is fitted into a shielding case 1. The head material body 7 contains magnetic cores 3 and 3 which are set into a pair of core supports 2 and 2. A coil 4 is wound around the basement of the core 3 via a bobbin 4a. The resin 6 is filled into the case 1 after the material body 7 is positioned into the case 1. Thus the body 7 is sealed to the case 1 in a body. The thermosetting resin is used for the resin 6 which contains mainly the polyester resin or the diallylphthalate resin and a reinforcing agent or a filler for example. Such resin 6 has <=0.1% forming shrinkage factor, <=0.2% water absorbing factor and <=150 deg.C forming temperature respectively. With this small forming shrinkage factor of the resin, no narrow gap is produced between the core and the case 1. This prevents the occurrence of the defective earth.

Abstract: PURPOSE:To make it possible to easily cut off the runner part of soft resin from a molded item at its gate by a method wherein the runner part of the soft resin is put on rigid resin, when the molded item having the construction consisting of two layers or rigid resin layer and soft resin layer is ejected with ejector pins. CONSTITUTION:The release of a molded item 10 is done by the simultaneous actions of ejector pins 7a and 7b caused by opening a retainer plate 1 and a movable retainer plate 2 or, concretely by the abutting of the ejector pins 7a against the runner part 4a of rigid resin and their ejection in the opening direction of a mold and by the abutting of the ejector pins 7b against the molded item 10 and their ejection in the opening direction of the mold. Since the runner part 4b of soft resin fuses integrally with the runner part 4a of the rigid resin, almost no elongation of the runner part 4b occurs even when tensile force is applied, resulting in cutting off the runner part 4b from a gate at the corner extending from said runner part 4b in the gate. Needless to say, at this time, the runner part 4a of the rigid resin is simultaneously cut off at the gate.
