Title: Method of winding plastic film
Inventor: YASUHARA TERUYUKI
IPC: B65H18/00
Filed: 1981-12-11
Abstract: PURPOSE:To enable a plastic film to be wound in a good wound shape with the generation of selvage heightening phenomenon being suppressed by cutting both selvage parts of a plastic film into a saw-like shape and by winding it with the selvage parts being shifted. CONSTITUTION:A rod 17 is reciprocated by a crank mechanism 18 when a motor 13 is driven, and therefore, a drive shaft 11 is vibrated. Accordingly, sliters 1, 1 are also vibrated so that both selvage parts of a film 2 on advance are cut into a saw-like shape. Then, the film 2 is wound on a paper spool 5 without the selvage parts being overlaped. Thereby, the ends 6 of the film 2  have a record disk-like shape, and therefore, the selvage heightening phenomenon does not occure even if there are raised parts due to, for example, poor cutting. In order to prevent this selvage heightening phenomenon, the sliters are vibrated in such a way that its amplitude is set in a range from 1mm. to 3mm., and the value obtained from the equation: amplitude (mm.) X time period (1/min) X outer periphery of paper spool (m)/film pulling speed (m/min) is set in a range from 0.001mm. to 0.3mm., thereby a film wounded on a spool without any selvage raised part may be obtained.

Abstract: PURPOSE:To reduce noise by a method wherein the bearing of a motor shaft, to which an impeller is secured, is pinches by an air guide of split constitution arranged at the outer periphery of the impeller while the whole body including the motor is covered by a split casing. CONSTITUTION:The impeller is secured to the tip end of the motor shaft and constitutes the rotary body 22 of the fan together with a rotor 17. The casing of the motorfan is split into two of more parts and a stator 26 of the motor is held by the lower casing 24 while the bearing 18 is pinches by two sets of air guides 23. Next, the stator is covered by the upper casing 25 and, thereafter, the outer periphery of two casings 24, 25 are fixed by a clamping band 28 to constitute the motorfan.

Title: Manufacture for magnetic disc
Inventor: WATANUKI KIICHI
IPC: G11B5/842
Filed: 1983-10-24
Abstract: PURPOSE:To control simply the layer thickness of magnetic paint on a disc base by providing a process dropping a paint, a leaving process and a layer thickness measuring process so as to control the leaving period depending on the measured layer thickness. CONSTITUTION:If the viscosity of paint is changed due to secular change in coating the magnetic paint through the turning of the base, the layer thickness is changed. Then the process F1 dropping the paint, the leaving period and the process F6 measuring the paint layer thickness after the end of the drying process F5 are provided. In making the measured layer thickness thicker, the shaking off time of the shaking-off process F3 is prolonged so as to increase the amount of removal. When the layer thickness is a specified value or below, after the paint is dropped at the dropping process F1, the leaving period is taken longer. The layer thickness is controlled simply by controlling the layer thickness of the paint, not by the number of revolutions of the base but by the leaving period, i.e., drying state in this way.

Title: Emulsion paint
Inventor: KURAHASHI YOSHIO
IPC: C09D121/00
Filed: 1983-10-27
Abstract: PURPOSE:To obtain a paint in which only its coating films formed by applying it to a substrate and drying it are bonded to each other as pressure-sensitive contact films, by dispersing a film forming element composed of a rubber latex and a water-soluble adhesive in a specified ratio in water. CONSTITUTION:A film forming element composed of a water-soluble adhesive and a rubber latex in a weight ratio of adhesive to rubber latex of 0.48-1.80 is dispersed in water. The rubber latex is a component imparting adhesiveness to the paint so that only coating films formed by applying the paint are bonded to each other as pressure-sensitive contact films. The water-soluble adhesive allows a coating film to exhibit an anchor against a substrate and is solidified inside the coating film by drying to form a part which does not contribute to the adhesion of the coating film. Hence, the adhesive is a component which is effective in reducing the adhesion of the rubber latex and losing the adhesion of the coating film to other materials.
