With these compositions, it becomes possible to provide a partially-oxidizing catalyst for a hydrocarbon having superior activity and selectivity in partially oxidizing the hydrocarbon in the presence of hydrogen and oxygen. Moreover, a partially-oxidizing method for a hydrocarbon is used for partially oxidizing the hydrocarbon by using any of the above-mentioned partially-oxidizing catalysts in the presence of hydrogen and oxygen. This method makes it possible to manufacture an epoxide from a hydrocarbon of the olefin family and also to manufacture an alcohol and/or a ketone from a saturated hydrocarbon, with high selectivity and high conversion.

Granted: 2000-12-11
Abstract: The present invention relates to a method and an apparatus for optical molding in which the objective of the present invention is to provide a small-sized optical molding apparatus at low cost. An exposure head 23 is formed by preparing a number of blue color LED, connecting an optical fiber to each of them, and disposing a GRIN lens at the distal end of these optical fibers. The exposure head 23 can form images with respect to the image at the distal end face of each optical fiber on the exposure range 24 of photosetting resin as an optical spot. Although the diameter of the optical fiber 55 is 0.5 mm for example, the size of pixels 71 within the exposure region 24 is by far small, e.g. 62.5 mu m. Thus, a number of optical fibers on the exposure head 23 are arranged in a matrix displaced in staggered relation in order for each optical spots 55 to be arranged at a pitch of 62.5 mu m of the pixel 71 in the major scanning direction (Y axis). While scanning the exposure range 24 with the exposure head 23 in the ancillary scanning (X axis) direction, a multiple exposure is conducted by making all optical spots 'ON' capable of lightening the pixels relative to individual pixels 71 to be exposed within the exposure region 24.

After proceeding multiple-surface examination on the cut sheet type optical film laminate intermediate body, proceed multiple-surface trimming to obtain the laminated optical film chip. In addition, the distance of the cutting lines of the first optical film intermediate body at this time is made equal to the width of a belt like second optical film.
