Title: Magnetic head support mechanism
Inventor: KOMATA KIICHI
IPC: G11B5/49
Filed: 1986-04-14
Abstract: PURPOSE:To attain the miniaturization and to improve the assembling oper ability by enclosing a magnetic head by a pocket, forming a V groove section and a taper section to the contact part between the base and the pocket, making them movable and supporting the base and pocket by an elastic body. CONSTITUTION:Since the magnetic head 11 is enclosed by the pocket 12, the insulation is facilitated and no alignment is called for, then the operability is improved. Since the pocket 12 and the base 13 are moved around a fulcrum 18, the deviation of position of the magnetic head 11 is avoided and number of components is reduced because of the simple constitution being the contact between the V groove section 15 and the taper section 14. Since the restoring movement is attained by supporting the base 13 and the pocket 12 by the elastic body 16, the magnetic head copes with a sliding face even if the object face such as a magnetic stripe traced by the magnetic head is deformed. Since the movable pocket 12 section consists of the magnetic head 11 and the pocket 12 enclosing it, the support mechanism is miniaturized.

Title: Apparatus for detecting leakage of mold for plastic
Inventor: ITOU HIROSHI
IPC: B29B13/00
Filed: 1981-06-01
Abstract: PURPOSE:To detect positively the presence of leakage of a mold by a simple apparatus, by sucking, under a certain pressure, air from a suction port of a mold, and detecting the evolution of bubbles in a liquid in a transparent container that will be caused by the sucked air. CONSTITUTION:After the molds 1 has been set, a suction apparatus 6 is actuated with an injection port 30 closed so that the air in the mold 1 is sucked via pipes 2, the closed containers 4, 5, 7 and pipes 60. As a result, the water 70 held in the closed containers 5 is transferred through pipes 3 and opened valves 51 into the closed containers 7. The sucked air in the closed containers 7 is released as bubbles through the water 70 from the ends of the pipes 2. If these is no leakage in the mold 1, the evolution of the bubbles will cease since air will not be sucked any further when the pressure in the mold 1 attains a predetermined pressure. Thus the absence of leakage in the mold 1 can be detected.
