IPC: H04N5/85
Filed: 1989-05-18
Abstract: PURPOSE:To realize consecutive recording/reproduction in a real time between discontinuous tracks by compressing an input moving picture signal in the case of recording and expanding the compressed moving picture signal at the time of reproduction to expand the compressed signal into the original moving picture signal. CONSTITUTION:An optical disk 12 is adopted for an external recording medium and is provided with a 1st recording/reproducing sector 17 and a 2nd recording/ reproducing sector 18 which are split radially with a length of 1/2 circumference of the circle. Then a moving picture recording/reproducing means is provided, which uses an optical head 13 provided to a slider 11 to scan the areas 17, 18. An input picture signal at a period of moving recording/reproducing is compressed and the circumferential direction of a recording medium is recorded with each passing time length of the recording/reproducing areas 17, 18 resulting from split by plural number in the circumferential direction of the recording medium. Moreover, an output moving picture signal from the recording/ reproducing areas 17, 18 at reproduction is expanded to reproduce the signal at the original moving picture recording/reproducing period.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To detect a position that is brought into contact with a piezoelectric substrate or non-piezoelectric plate which is provided on it and to display information that corresponds to the position on a display screen. SOLUTION: When an electric signal is inputted from interdigital electrodes TO, TX and TY, an elastic surface wave is excited on a piezoelectric substrate 1. The elastic surface wave is converted into an electric signal that has a phase θbase and outputted by an interdigital electrode RO and also converted into electric signals EXi and EYj by interdigital electrodes RX and RY respectively, but they are not outputted. However, if they come into contact with the intersection of a position FXx and a position FYy on the substrate 1, electric signals EX-x and EY-y are outputted from interdigital electrodes RX and RY respectively.  The intersection of the positions FXx and FYy is specified from the difference between phases θX-x and θbase of the signal EX-x and the difference between phases θY-y and θbase of the signal EY-y , and information that corresponds to the intersection is shown on a display screen.

Abstract: PROBLEM TO BE SOLVED: To improve productivity and quality by applying a blow molding where a die is closed after a parison hung from a die head catches a pin shaft and a nozzle and then the air is blown into the inside through the nozzle. SOLUTION: Thermoplastic resin (vinyl chloride resin) plasticized in an extruder is pushed on as a cylindrical parison from a die head 6. The parison P hangs down to the position that its top covers a pin shaft 54 and a nozzle 53 of a holder 5. Then a right die 4a and a left die 4b are pushed together so that a blow mold B closes with the parison P holding the pin shaft 54 and the nozzle 53. After the mold is completely closed, the air is blown into the parison through the nozzle 53 of the holder designed to shape out a funnel where compressed air runs through a tube 9 into a block 51 and blows out from an air outlet. By this operation the parison P is expanded up to melt fixed to the face of a cavity 46 so as to form a shape identical to its inner face.
