Filed: 1989-09-21
Abstract: PURPOSE:To prevent vignetting resulting from skew and to satisfactorily transfer an image by providing a skew correcting means on a carrying path for a photosensitive material that is not exposed yet and a carrying path for an image receiving material and for a photosensitive material that is not superimposed. CONSTITUTION:The skew correcting device 80 includes a roller 21 carrying the photosensitive material 16 from a turning-over part 72 and a tilted, rotating shaft roller 81 which is slantwise arranged in a flapper 74 with respect to the rotary shaft of the roller 21. A side plate 82 is provided on the side of the carrying path to extend from the side of the roller 81 to the carrying roller 23 of an exposing part 21. The flapper 74 jumps upward when the photosensitive material 16 is carried by the roller 21 from the turning-over part 72 to empty a path from the roller 21 to the roller 23. The roller 81 moves the photosensitive material 16 carried by the roller 21 from the turning-over part 72 to the side 82. Since the interval between the rollers 21 and 23 is set longer than the width of the photosensitive material 16, the photosensitive material 16 has a position in which it is regulated only by the roller 81, and its side abuts on the side plate 82 to correct skew.

IPC: E02D17/20
Filed: 1994-10-07
Abstract: PURPOSE: To enhance a greening condition by using, as a greening base material to be sprayed on the face of slope or the like, a mixture of Kanuma earth and/or tuff loam of specified grain size and distribution, a fabric material, manure, seeds, and the like. CONSTITUTION: A greening base material, 2mm or less in grain size, is a mixture of Kanuma earth and/or tuff loam, partly 0.75mm or less in grain size in the 20% to 40% range, a fabric material, manure, seeds, erosion preventive, and nodulizing agent. When greening work is executed, this greening base material is charged into an agitator for agitating, and is forcibly fed by a pump and is sprayed on the face of slope or the like. In that case, since the Kanuma earth and the tuff loam exists in the stratum beneath several meters under the ground surface and is a good quality soil free from the seeds of weeds and the roots of plants, the harm of the weeds can be prevented. Further, since the range of grain sizes of the Kanuma earth and the tuff loam have been specified, the sedimentation inside a hose at the time of spray can be prevented, and also the flow value can be satisfied.  Thus, the purpose of green can be properly achieved, and also workability can be enhanced.
