  • Patent number: 5627650
    Abstract: An image forming apparatus has a function for recognizing a sorting mode, a function of recognizing a copy specification, a function of storing an original image, and a function of rotating this stored image. The apparatus has a function of alternately outputting sets of copy sheets in an angular difference of about 90.degree. in accordance with the copy specifications. An operator can discriminate the sets of copy sheets from each other using landscape and portrait copy sheets without using a mechanical sorter mechanism. When a binding unit is added to this image forming apparatus, the apparatus has a function of reversing the reading order of the pages of each set to reproduce the images and alternately binding and outputting the copy sheets at an angular interval of about 90.degree. in units of sets.

  • Patent number: 5277729
    Abstract: One method of manufacturing a polarizable electrode for an electric double-layer capacitor includes, in order, the steps of: preforming a kneaded substance of fine carbon powder, a polymer resin containing fluorine, and a liquid lubricant into a sheet-type preform; adjusting the content of the liquid lubricant in the sheet-type preform to 10 to 47 percent by weight; shaping the preform into a prescribed thickness, optionally but advantageously with heated rolls; and then substantially removing the liquid lubricant from the preform. In another disclosed method, first the liquid lubricant is substantially removed, and then the sheet-type preform is rolled with rollers that are heated to substantially 90.degree.-120.degree. C. In either of the above methods, the rollers are controlled to have a circumferential speed of 0.7-5 m/min and the rollers shape the preform into a sheet substantially 0.04 to 0.5 mm in thickness for serving as a polarizable electrode.
