  • Patent number: 10947373
    Abstract: The present invention relates to a polypropylene resin composition for a microporous film which can reduce the product defect rate due to stabilization of porous formation by stabilizing film formation and also can obtain a film suitably usable for a separator, a filtration membrane, a separation membrane and a filter since the microporous film can be thinned due to high rigidity, and more specifically, relates to a polypropylene resin composition for a microporous film wherein the composition comprises 5 to 30% by weight of polypropylene resin (X) having specific MFR, molecular weight distribution Mw/Mn by GPC, melt tension (MT), branching index g? and mm fraction of the propylene unit triads by 13C-NMR, satisfying specific conditions concerning gels and having a long chain branched structure and 95 to 70% by weight of polypropylene resin (Y) having a specific MFR and excluding the polypropylene resin (X).

  • Publication number: 20030031462
    Abstract: A time stamping part and a packet storing part are separated from each other. To simplify data transfer from the time stamping part to the packet storing part, the time stamping part adds time information after a captured packet, and outputs the packet directly through a port for the packet storing part. The packet storing part captures all packets sent from the time stamping device regardless of their destinations, thereby preventing the time stamping part from performing extra processing.

  • Patent number: 5684603
    Abstract: It is sought to provide a coding apparatus which permits high efficiency coding of bi-level images with black-and-white pixels halftoned with error diffusion algorithm. An image input/pixel selection unit selects, from an input image as a bi-level image with black-and-white pixels halftoned with error diffusion algorithm, first selected pixels with respect to a pixel "?" to be coded and second selected pixels as peripheral pixels with respect to the first selected pixels. The first selected pixels are fed to a pixel pattern binary scale translator for translation into a binary number. The second selected pixels, on the other hand, is fed to a pixel value adder for counting of black pixels. The count is fed to a binary scale translator for translation into a binary number. The binary number outputs of the pixel pattern binary scale translator and the binary scale translator are combined to be input to an address input terminal of a ROM having a coding information table.

  • Patent number: 5345317
    Abstract: An original grayscale image or color image to be coded is processed by a bi-level image mingled still image coding system to produce a differential image. The original image and the differential image are compared for each pixel block. Only those of the pixel blocks for which the bi-level image mingled still image coding system will be more efficient than a natural image coding system are encoded by the bi-level image mingled still image coding system, and the other pixel blocks are encoded by the natural image coding system. The coding method of the present invention is directed to a grayscale or color image containing an area where pixel values undergo an abrupt change, such as an edge of a letter, or a document with multi-color and natural color images intermingled therein. The method of the present invention obtains a less deteriorated coded image even from an image in which the edge area is very blunt, and moreover, the invention permits high efficiency coding.
