Abstract: A multi-level image is encoded through dither conversion and hierarchy encoding with high image compression ratio and satisfactory image quality for low resolution images. An original multi-level image is first reduced so that a plurality of reduced images are obtained. Each reduced multi-layer image is then dithered to bi-level image, and finally each dithered bi-level image is encoded starting the smallest and the lowest resolution image to the largest and the highest resolution image. No temporary memory for reduced multi-level image is necessary, as a common multi-level line memory (LM2, LM3, LM4) doubles for storing a reduced multi-level image and a temporary memory for effecting dither conversion.

Abstract: A light-image forming material comprising a support having provided thereon a light-image forming layer comprising microcapsules containing an oxidative-developable leuco dye and a photo-oxidizing agent, and a reducing agent as essential ingredients, wherein the material also includes a covering layer or intermediate layer containing a film-forming high-molecular binder and/or an inorganic or organic pigment.

Abstract: An image-forming material comprising: (a) microcapsules, in which at least one leuco dye capable of developing a color by oxidation and at least one photooxidizing agent (preferably a combination of a lophine dimer and an organic halogeno-compound) are enclosed together, and (b) at least one reducing agent not enclosed in the microcapsules (preferably present in the form of an emulsified dispersion), thereby achieving image formation in a completely dried condition, and ensuring excellent freshness keeping property, image reproducibility and fixability.

Abstract: This invention discloses a heat sensitive recording material having a heat sensitive layer on a support; either of a color forming material or a developer which are contained in the heat sensitive layer is encased in a microcapsule. Since a plasticizer for a wall material of the microcapsule and a compound having an effect to depress the melting point of at least one member out of developers, a color forming reaction is carried out smoothly under a recording condition, therefore, a density of an obtained image is sufficient. Especially good results are obtained when a macromolecule substance selected from a group of polyurethane, polyurea, polyamide, polyester and polycarbonate is used as a wall material of the microcapsule. A coloring reaction assistant may be contained in any place of the heat sensitive layer.A preferable plasticizer can be selected from a group of phenols, alcohols, ureas, sulfonamides, carbamates and aromatic methoxy compounds.

Abstract: An encoding method for facsimile signal which is characterized by encoding data of a line selected out of the all lines of input facsimile signals in a manner of skipping over a predetermined number of lines according to a predetermined encoding method and by encoding the data of one of the thus skipped-over lines from a basic element of higher picture quality contribution judged with reference made to the data of the lines preceding of and/or subsequent to the encoding line which have already been encoded.

Abstract: A coding method for a multilevel-gradated picture signal is disclosed, in that a series of binary codes obtained by processing a multilevel-gradated original picture signal for binary representation are segmented every predetermined number n of picture elements on each scanning line to form blocks, respectively capable of assuming value "0" to "2n-1"; and the value of a block having changed its value and its position on the scanning line are encoded so as to be reproduced on the reproducing side.

Abstract: A window molding for an automobile including a leg embedded in an adhesive for fixing a peripheral edge of a window to a flange of a window opening, according to the invention comprises a lip extending from an inner surface of a head of the molding and joined to an inner peripheral wall of the window opening to inhibit any relative movement between the molding and panels of a vehicle body, thereby preventing any entrance of fine particles such as fine sand and dust therebetween to prevent coating films of the vehicle body from being damaged and any occurrence of rust in the proximity of the window opening.

Abstract: A window structure of a vehicle body comprises a wall portion forming part of the vehicle body and defining an opening therein; a window panel closing the opening and having at least one edge portion extending along and spaced apart inwardly from the wall portion for forming a gap between the wall portion and the edge portion; a resilient molding having a decorative trim portion bridging the window panel and the vehicle body for covering the gap, a stem portion integral with the decorative trim portion and extending in the gap, and a plurality of retrorse fins extending outwardly from both sides of the stem portion and angled toward the decorative trim portion for engagement with the edge portion of the window panel and the wall portion of the vehicle body; and retaining means for retaining the retrorse fins in engagement with the edge portion of the window panel and the wall portion of the vehicle body.
