Title: Plastic granulated substance with non-dispersive electroconductive fiber bundle
Inventor: RUISU KORUNERISU KURIJIYAA
IPC: B29K105/12
Filed: 1989-10-20
Abstract: PURPOSE: To enhance the barrier properties of an obtained molding compd. by constituting a granulated material of granules in which a specific amt. of electrically conductive fiber bundles are incorporated in a specific dispersing degree. CONSTITUTION: A plastic granulated material comprises granules in which 0.3-4 vol.% electrically conductive fiber bundles are incorporated in a dispersing degree of 0.10 or less. The dispersing degree is a reciprocal value of the vol. ratio (%) of granules occupied by electrically conductive fiber bundles containing 60-20,000 fibers and measured by a threshold value method. The selected threshold value is determined by the amt. of fibers present per a surface area of 1 mm and must be a value such that the area covered with fibers cut in a value cross section is at least 5% of the whole of the surface. The fibers have a length of 4-8 mm for example and impregnated with a resin. The plastic material is usually a thermoplastic polymer compsn.  When this plastic granulated material is used, the clogging of an extruder is avoided and, in spite of a low dispersing degree, that is, the slight distribution of fibers in granules, this material is suitable for forming a molding compd. having excellent barrier properties by processing.

While exposures over the whole range of the limit set values are calculated under the condition that a print control system is set so as to realize the maximum exposure. Thus, two tables are produced so as to calculate the exposure to the whole combination of the limit set values and the print set values. According to the results of the calculations, a calibration page is printed so as to calculate the exposure for obtaining a desired density and further the set values of a control system by measuring the densities to the set values over the whole range in order to form an output lookup table.  Printing is performed on the basis of this table.
