Title: Transmission system for plural channel video signal
Inventor: OKANO TAKASHI
IPC: H04N19/423
Filed: 1987-12-09
Abstract: PURPOSE:To reproduce a picture with smooth movement even when movement of picture exists without deterioration in the vertical resolution in case of less movement of picture by selecting two fields constituting one frame in a multiplex video signal through the combination of two fields parted by a prescribed field number in each channel. CONSTITUTION:A video signal of each channel is retarded by a period corresponding to two frames by a 2-frame delay circuit 11 and becomes an (a) input of a changeover switch 12. The changeover switch 12 selects the odd number field in two-preceding frame being an (a) input in case of an odd number field based on the discrimination output of a field discrimination circuit 13 and selects the existing field in case of an even number field. Thus, the two fields constituting one frame is the combination of the even field of the existing frame and the odd number field in two preceding frames. As a result, since the missing period of the signal is interpolated by the one field signal fetched in 2-frame period, a smooth reproduction picture not causing vibratory movement is obtained.

Title: Edible foil having pattern shape and manufacture thereof
Inventor: ASANO EIICHIRO
IPC: A23P1/08
Filed: 1987-12-10
Abstract: PURPOSE: To expand the utilization of edible foil while facilitating the handling thereof by providing wafer layers on the upper and rear surfaces of the edible foil and molding a pattern shape on the paper materials superposed on the outsides of the wafer layers. CONSTITUTION: Wafers 2 are provided on the upper and rear surfaces of gold or silver foil 1 and both of them are easily brought to a close contact state by generated static electricity and brown papers are applied to the outer surfaces of the wafers 2. If a plurality of brown papers 3 are superposed in case of necessity, the tension of surfaces is effectively enhanced. A pattern shape is formed by cutting the resulting superposed matter by acissors, a cutter or a press to form an arbitrary pattern. Since the wafer layers and the paper materials are superposed on the foil and the outermost side is the paper material, sanitariness as edible use is held and safe handling is enabled in both of transport and preservation.  At a time of use, the wafer layers are exposed by removing the paper materials and the foil can be handled by prinching the wafer layers and, since it is unnecessary to directly come into contact with the foil, the foil does not receive any effect and is not bonded itself or rounded and can be extremely easily handled.
