Title: Dummy sheet in twin roll type continuous casting and method for winding thin cast slab
Inventor: UEJIMA YOSHIYUKI
IPC: B22D11/08
Filed: 1993-11-29
Abstract: PURPOSE:To prevent the breakage without developing bending and thinning part by using a short dummy sheet having the length in the naturally hanging down condition below casting rolls at the lower end thereof until the position, in which the thickness of a thin cast slab is unsteady state, completes to pass through the casting rolls. CONSTITUTION:The lower end of the dummy sheet 8 is freely hung down until the unsteady position of the thickness of a thick solidified shell part or the thin cast slab 1 completes to pass through a kissing point 6. In this condition, a connecting part of the dummy sheet 8 and the thin cast slab 1 is stretched with the dead wt. of the dummy sheet 8, and the bending is not developed. Further, the dummy sheet 8 has length L1 as the figure is short, this dead wt. is light, and the excess tension stress is not given to the connecting part of the dummy sheet 8 and the thin cast slab 1 and the thinning part is not developed. By this method, the breakage of the thin cast slab 1 can be prevented and further, the cast slab is smoothly carried to a winding reel and can be wound.

Title: Still picture recorder and reproducing device
Inventor: HIRAUCHI YOSHIO
IPC: H04N5/91
Filed: 1990-11-02
Abstract: PURPOSE:To display a picture with picture quality suitable for a screen switching interval by using and reproducing all signals recorded on a medium when the screen switching interval is sufficiently longer than a reproduction required time of a picture from the recording medium and interpolating recursively a signal subjected to sample processing in terms of layers when shorter so as to reproduce the picture. CONSTITUTION:When a screen switching interval is longer than a time required for reading a recording signal included in all layers, all signals are transferred to a frame memory 3 in matching with a switching timing to a succeeding screen and outputted from a terminal 10. On the other hand, when the switching interval to a succeeding screen is shorter than the required reproduction time, the read is interrupted from a medium up to a layer able to be reproduced in a time closest to the screen switching interval and not in excess thereof, succeeding deficient picture elements are generated by interpolation and outputted from the terminal 10 in time of the switching timing. However, when a time margin exists till the start of reproduction of the succeeding screen, the signal read out of a higher layer is restarted and the deficient picture element is replaced with a signal read newly.

Title: Parison and blow-molded container
Inventor: OTA TAKAO
IPC: B29L22/00
Filed: 1987-11-27
Abstract: PURPOSE:To obtain a container having excellent transparency, gas- impermeability and mechanical property, by forming a parison having a special laminating structure from different raw resin materials. CONSTITUTION:A blow-molding apparatus comprises a cylinder 1 for resin A and a cylinder 2 for resin B. In order to form a multi-layer resin material, the apparatus further comprises a change-over valve 15, connecting conduit 7 and a resin laminating device 11. The change-over valve 15 is suitably switched to allow a nozzle 5 extended outwardly from the cylinder 1 to communicate with the connecting conduit. An injection pressure is simultaneously applied to both the cylinders 1 and 2, so that the resins A and B is introduced into the resin laminating device to form a multi-layer resin material which has a specially laminated structure of resin A3 and resin B4 in molten state. The multi-layer resin material is then injected into a molding cavity 14 of a plastic molder. The laminating volume ratio of resin A to resin B preferably ranges from 1:40 to 40:1. A parison thus obtained not by thoroughly mixing two sorts of resins with each other but by specially laminating these resin, is subjected to biaxial orientation blow-molding to produce a container having an improved transparency and gas-impermeability.
