Abstract: PURPOSE:To provide a molded mask neither caught nor butted by the skin by scattering active carbon on a bulky unwoven cloth containing thermoadhesive fibers, laminating a surface layer material including thermoplastic fibers on the unwoven cloth for molding, next putting the molding between a supersonic horn and an edge-like metal mold to seal and fuse off the molding by the supersonic wave. CONSTITUTION:Active carbon is scattered on a bulky unwoven cloth including thermoadhesive fibers and then heated to fusion-weld the thermoadhesive fibers and fix the active carbon to the bulky unwoven cloth. A surface layer material including thermoplastic fibers is laminated on the unwoven cloth for molding. Next, the molding is put between a supersonic horn and edge-like metal mold to be sealed and fused off by supersonic waves. Then, the active carbon 14 is widely dispersed between the constitutional fibers of the unwoven cloth 13. Similarly, the thermoadhesive fibers adjacent to the active carbon 14 are dispersed between the constitutional fibers of the unwoven cloth 13. Thus, by heating the unwoven cloth and fusion-welding the thermoadhesive fibers, the active carbon 14 is fixed by the fusion welding of the thermoadhesive fibers dispersed adjacent to the active carbon 14, so that a molded mask with a good feeling of wearing can be provided.

IPC: G06F3/12
Filed: 1992-11-30
Abstract: PURPOSE:To attain more correct prediction, and to attain effective scheduling for plural queues by predicting the processing time of data from printing history information in the past. CONSTITUTION:A printing request managing part 8 having received a printing request predicts the data conversion processing time to format capable of being printed at printing parts 4,4'... from the printing history information in the past. It registers and holds the data processing time predicted in this way in a printing history information holding part 7. If there is no retained printing request presently, it investigates the state of printing devices 1, 1'... and the queues 5, 5'.... If there is the queue which has no processing waiting request among the queues, it loads the printing request in it, and if there is no queue which has no processing waiting request, it registers the printing request in a list holding part 9, and a retention period starts. If there is the retained printing request, it registers it in the list holding part 9, and waits for the end of the retention period while accepting other printing requests. The end of the retention period is a case that some definite time elapses or the case that one of the printing devices has no processing waiting request.

Title: Yarn end taking-out method for yarn package and its device
Inventor: KOBAYASHI NORIYUKI
IPC: B65H57/22
Filed: 1994-12-22
Abstract: PURPOSE: To safely and surely take out a yarn end which is temporarily fixed to the outer circumferencial face of a package by blowing compressed air in the releasing direction of the cut yarn from a package after cutting yarn on the other side of yarn continuing to the package and then rotating the package in the yarn winding direction. CONSTITUTION: After a suction nozzle 9 is lowered, a confounding yarn end (ya) is sucked and at the same time a package(P) is rotated in the yarn winding direction by a prescribed quantity. When yarn suction is confirmed by the suction nozzle 9, the suction nozzle 9 is raised so that the last winding yarn is made to float up from the package(P). The yarn (yb) in one side of the yarn continuing to the package(P) is cut by a cutter 14 and the cut yarn is sucked by rotating the package(P) in the yarn releasing direction. After rotating it by a prescribed quantity, the yarn on the other side is cut by a cutter 15 and at the same time compressed air is blown from the nozzle 30 in the direction that the cut yarn is released from the package(P) so that the free end of the cut yarn is trailed out in the releasing direction.  After that, the package(P) is rotated in the winding direction and the free end of the yarn is set in the hung state.
