IPC: B29C45/14
Filed: 1986-02-12
Abstract: PURPOSE:To manufacture a molded product with excellent electromagnetic wave shielding property by employing a plastic sheet which is one component of a composite sheet and the heat deformation temperature of which is higher than that of a plastic to be injected over the composite sheet for molding the part. CONSTITUTION:A plastic sheet 11, onto which an electrically-conductive layer 12 is laminated in order to obtain a composite sheet 1 and the heat deformation temperature of which is higher than that of a plastic to be injected over the composite sheet for molding a part, is employed. The difference between their heat deformation temperatures is preferably 10 deg.C or more and, when the difference is 15 deg.C or more, the effect by the difference is ensured. By said difference, the phenomenon of the pushing-away of the electrically-conductive layer caused by the melting of the plastic sheet in th vicinity of a mold gate 31 due to the heat of molten plastic given off during injection molding is avoided and no destruction of continuity of the electrically-conductive layer develops. Accordingly, the electromagnetic wave shielding property of the obtained molded part is surely retained.

Title: Detector of neck part of can
Inventor: SAITO CHIYOKO
IPC: G06T7/00
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To optically detect a defect in a neck part of a can by photographing a reflected light from a mirror by a CCD camera which is provided in the upper part of a light projecting part in concentric with the light projecting part. SOLUTION: A projected light from a ring light projecting part 5 is incident on the whole circumference of a neck part 4 of a can 1. The incident light on the neck part 4 by this projecting light is reflected here, and further reflected on a reflection face 8a of a ring mirror 8 so as to be incident on the CCD camera. When the can 1 approaches to the bottom of the ring mirror 8 so as to be concentric with the mirror 8, it is photographed by the CCD camera. A recessed part 4bL in the neck 4 which is an inwardly recessed curved surface extends in the intermediate part of a projecting curved surface 4a. Therefore, the bottom end part 4b of the recessed part 4b is formed into a curved change part changing from the recessed curved surface to the projecting curved surface so that an image of this part is reflected brighter than other parts.  In a signal processing part, when a point brighter than an adjoining part is present on a circumference where the projecting curved surface 4a is reflected, it is thus detected to have a recess.
