    Abstract: PURPOSE: To degauss a perfectly packed pancake by means of a fast cycle time by permitting a recording carrier to be insertable into a coil with a lift-up device in an axial line direction. CONSTITUTION: The magnetic recording carrier 8 is carried to a degaussing device 1 in an arrow direction on a conveyor belt 7. The device consists of a solenoid, providing cylindrical coil windings, and the coil windings are driven with a charged capacitor 6. When the recording carrier 8 reaches the device 1, the conveyor belt 7 is stopped, and the recording carrier 8 is lifted-up into the inner space of the device 1 by the lifting device 5. Therefore, the recording carrier 8 is coaxially arranged in the coil, the capacitor 6 discharges with the coil windings at this time and the recording carrier 8 is perfectly and efficiently degaussed by an alternating magnetic filed which occurs in a form of a damped vibration.

    Abstract: PURPOSE: To realize an excellent winding by providing tape winding hub device in which individual winding hubs have a winding surface for an individual information carrier tape and an inner gap, and an annular body has a circumferential surface of a reception part having an inner circumferential surface to be fitted to a winding spindle and an inner circumferential surface to be fitted and inserted in an internal gap of the individual winding hub to reduce or automate the attachable/detachable work. CONSTITUTION: A spring member 9 to be brought by a recessed part formed in a substantially U-shape in an upper circumferential surface edge piece and a flange part 7 of an annular body portion 6, is arranged on a circumferential surface of the reception diameter D1. A spring 11 having a hook part on a tip formed as a member 9 has an appropriate spring action stroke (a) in the radial direction, and also has a recessed part to receive the width h of an individual winding hub 10 in the axial direction. When the individual winding hub 10 is pressed onto a hook spring 11 from the right, it is held at the final position. This winding hub 10 and the annular body 5 are formed of an inexpensive thermoplastic resin in a recyclable manner, and the fitting/removing work to/from the annular body 5 of the winding hub 10 can be easily and rapidly achieved.

    Abstract: PURPOSE: To provide a core which can easily be produced at a low cost for the replacement of a less productive, high-priced coil core which is formed by injection or blow molding from a hardly-recyclable, comparatively hard synthetic resin. CONSTITUTION: In a recyclable, hollow-cylindrical supporting core which has no flange and which can be produced by injection molding for winding up a tape recording media, a plurality of arms 3, 3', 3" are provided which extend from the gating point 2 of the material for the supporting core 1 to the inside diameter of the supporting core at an opened end and which may be angled off, as material compounds for the purpose of fixing and serving as holding grips.

    Abstract: PURPOSE: To simply, effectively press a hub to a winding element and to accurately hold a tensioning means by providing a plurality of elastic elements uniformly distributed on a periphery over an inner periphery of the hub, and forming the element in a shape of a bent arm. CONSTITUTION: The hub 1 has an outer part having a cylindrical surface 12 for winding a magnetic tape, an inner cylindrical part 3 and a radial web 13 disposed therebetweeen. A plurality of elastic elements 2 are extended from the part 3 and formed in an arm-like state radially bent. Further, radially protruding protrusions 7 are provided at ends of the elements 2. The hub 1 is compressed in winding on the hub 1 of a magnetic tape. Accordingly, before winding, the hub 1 is brought into contact with the hub holder 6 only at the protrusions 7. Meanwhile, when the tape is completely wound on the hub 1, the hub 1 is held by the elements 2 and the protrusions 7, and the hub 1 is brought into contact with the winding shaft 9 or the holder 6.

    Abstract: PURPOSE: To constitute the spool for a tape, which reduces the shrinkage at the time of winding of the tape and eliminates its deviation when the tape is put one over another, without using a reinforcing material like glass fiber. CONSTITUTION: The spool consists of an outside ring 2 and an inside ring 3, which are coupled together by elastic intermediate elements 4 that are decentralized and arranged equally in the circumferential direction. In this case, the outside ring 2 is formed to an H shape in its cross section and the intermediate elements 4 are formed in a ring shape.
