Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To reduce a bit quantity necessary for coding while suppressing the deterioration in a picture quality in the coding of the picture. SOLUTION: A shape extraction means 2 binarizes a picture signal 1 by a prescribed threshold value to extract shape information. Next a shape coding means 4 codes this shape information by a binary picture coding technique to output as a shape coded signal. On the other hand, an off-shaped pixel substituting means 6 inputs shape information 3 and the picture signal 1 to judge the in-shape or off-shape by shape information 3 and to substitute off-shaped pixel of the picture signal 1 with such a prescribed rule as reduces high frequency components. As the result, the coding efficiency of a picture signal coding means 7 at an object area boundary part is improved.

IPC: B29C65/08
Filed: 1985-07-03
Abstract: PURPOSE:To obtain the laminate excellent in adhesive property by a method in which after a base material made of olefin family polymer and a skin material have been lapped upon each other, the skin material covers the end portion of the base material and wraps it in, and then the skin material is welded to the base material by the treatment of an ultrasonic welder.

The base material is covered with the skin material, and when they are treated with an ultrasonic welder, the base material is welded to the skin material only at its rear surface. The base material is not welded to the skin material at its front surface. Thus, by such a treatment, a welded trace does not remain on the front surface of the product. To obtain an excellent appearance without welding the front surface of the product, the process welding only its rear surface is most suitable.

Abstract: PURPOSE:To form linearly polarized light reducing the expansion of beam width and preventing the generation of uneven brightness in projected beams by using a polarizing film for reflecting either one of p-polarized component light and s-polarized component light out of light projected from a light source and for transmitting the other, a prism reflecting face, a reflector, and a synthetic prism to constitute the polarized light forming optical device. CONSTITUTION:Light from the light source 6a is converted into parallel beams by a curved mirror 6b, the parallel beams are made incident upon the polarizing film 3 and its p-polarized component is transmitted through the film 3 and refracted and projected by/from a synthetic prism string 2. On the other hand, the s-polarized component is reflected by the film 3, reflected by the prism reflecting face 4 and converted into p-polarized light, which is transmitted through the film 3, changed its direction by the reflector 5 and projected from the prism string 2. Since the light directly passed from the light source side through the film 3 and reflected light from the reflector 5 are refracted on respective small faces having respectively different inclinations and projected, respective signal directions are aligned. Since both the polarized components are uniformly mixed, the generation of unevenness in brightness or color can be prevented.

Abstract: PURPOSE:To reduce the weight, to suppress the entry of unnecessary external light and to obtain superior wearing sensation by providing a chamfered part in a specific shape which maintain a proper visual field to the peripheral part of a spectacle lens after an edge slide processing is performed. CONSTITUTION:The angle A between C and OA is <=45 deg., so light which is made incident on the chamfered part from a convex surface side and reflected by it seldom travels to the convex surface, and consequently the chamfered part is inconspicuous apparently and the influence of the incidence of reflected light on an eye from the convex surface is reduced. Further, the mean radius of curvature of the sectional curve of the chamfered part is <=30mm. and extremely large surface refracting power is obtained. The chamfered part positioned at the ear side (left side in figure) is very wide and maximum width Wmax is >=6.0mm.; and the chamfered part positioned at and below the noise side (right side in figure) is narrow and minimum width Wmin is <=1.5mm.. Namely, the chamfering effect is given priority to the effective visual field at a peripheral part distance from OC and the effective visual field is given priority to the chamfering effect at a peripheral part close to OC.

Abstract: PURPOSE:To reproduce a copy image free from ghost image, by applying an electric field of the reverse polarity of the primary charging before or after the primary charging, and forming a space charge uniformly in the photoelectric conductive layer, and removing the image memory. CONSTITUTION:Before charging a photosensitive drum 1 uniformly primarily by means of a primary charger 2, an electric field of the reverse polarity of the primary charge is applied on the photosensitive drum 1, which is made of surface insulating layer, photoelectric conductive layer, and conductive layer, in three layers in all, by means of a corona discharger 18 of negative polarity, etc., then the potential on the photoelectric conductive layer is converged in a constant saturated potential by the avalanche phenomenon by the charge charged on the drum 1. As a result, a space charge is uniformly and evenly formed in the photoelectric conductive layer, and the residual image memory of the previous photoconductive layer is erased, and the residual history on the photosensitive drum 1 is erased. Therefore, an intermediate copy image free from ghost due to remaining history on the photosensitive drum may be reproduced. Or, the same effect may be obtained when the discharger 18 is located behind the charger 2, between the charger 2 and the secondary corona discharger 3 for forming latent image by exposure.
