Title: Manufacture of container cover
Inventor: NAKADA AKIRA
IPC: B32B7/12
Filed: 1985-05-22
Abstract: PURPOSE:To prevent metal foil from being corroded and improve the sealability of the foil by a method wherein the thermoplastic resin on the inside of a panel is softened and stretched so as to cover the edge of the panel in a container cover, the opening of the metal foil panel made of which is covered by a sealing piece. CONSTITUTION:A container cover 1 consists of a panel part 6 made of metal foil 3, onto the inside of which thermoplastic resin 4 is provided, and a sealing piece 2, which covers the opening 7 provided on the panel part 6. In the above- mentioned container cover 1, the panel part 6 and the sealing piece 2 are pressed to each other by a heating pressing means 24 and a pressing means 21 and, at the same time, the thermoplastic resin 4 on the inside of the panel is softened and stretched in a shape 14 so as to cover the opening end 8 of the panel. Because the opening end 8 is covered by the stretched part 14, no metal foil 3 exposes and consequently not only the possibility of corrosion is precluded but also the joining between the opening and the sealing piece becomes tight and the sealability of the foil is improved.

Title: Video printer
Inventor: KAWAKAMI MASATADA
IPC: H04N5/91
Filed: 1990-04-24
Abstract: PURPOSE:To reduce the print time by dividing video signal information by one pattern timewise, storing the divided information, storing it into plural memories, reading the stored information simultaneously, obtaining plural print data arranged vertically within 1H period, storing them by one line and printing out it. CONSTITUTION:After an input video signal Vi is separated into a luminance signal and a color difference signal by a YUV circuit 1, they are converted by an A/D converter 2. A memory control circuit 11 writes at first a data of an odd number field to a field memory 3a and writes a dat of an even number field to a field memory 3b after the end of storage. At printing, the picture data read from the memories 3a, 3b is latched in latch circuits 7a, 7b by the control of the control circuit 11 and stored in one line memory 9 by a print control circuit 8. Thus, two odd/even number field data are obtained for 1H period in this way, and the processing is repeated for 1V period and when all line data by one frame are stored in the memory 9, the data is fed to a print head 10, by which the data is printed out. Thus, high speed printout is attained with simple constitution.

Abstract: PURPOSE:To easily carry out the test of insulation restoring characteristics, by providing a first loop line as a non-vibratory system and a second loop line as a vibratory system to rapidly carry out the cut-off of a recurrence arc current due to a sample feeder. CONSTITUTION:A large capacity condenser 1, a making device 2, a reactor 9, a resistor 3 and a condenser 12 constitute a first loop line and constants of each elements are properly set to form a non-vibratory system. On the other hand, a second loop line constituted from the condenser 12, a reactor 10, a resistor 11 and a sample feeder 5 are set in the constants of each elements thereof so as to form a vibratory system. When the condenser 1 is charged and the making device 2 is subsequently inputted prior to testing, voltage between terminals of the sample feeder 5 is raised at a rising ratio determined by th time constant of (C4+C12).R11 but, when exceeds the voltage resistance of the sample feeder 5, recurrence arc is generated to supply a current to the second loop line. Because the second loop line is the vibratory system, a saw-tooth shaped voltage wave form is obtained by a measuring instrument 8 and, even if either one of media is used as the arc extinguishing medium of the sample feeder 5, the test of insulation restoring characteristics can be certainly carried out.

Abstract: PURPOSE:To obtain the title filter capable of rapidly separating oil and water by scooping up the water floating on the surface of oil with the sintered body constituting the filter, consisting of a resin having specified critical surface tension, and having specified porosity. CONSTITUTION:The sintered body consisting of an oil-permeable resin such as polyethylene and polypropylene having <=40dyne/cm critical surface tension is formed into the filter having 30-80% porosity shown by equation I. Consequently, when the water floating on the surface of oil is scooped up with the filter along with the oil, the oil alone permeates through the filter, the water remains on the filter, and hence a small amt. of water floating on the surface of oil can be rapidly and efficiently separated.
