  • Patent number: 7081510
    Abstract: The invention provides a shell material for recording media comprising an alloy between an acrylonitrile-butadiene-styrene resin and recovery polyethylene terephthalate, the content of recovery polyethylene terephthalate in the total amount of the alloy being in the range of 5 to 80% by mass. The invention also provides a shell material for recording media comprising an alloy between an acrylonitrile-butadiene-styrene resin and recovery polyethylene terephthalate and having a window part. The content of recovery polyethylene terephthalate in the total amount of the alloy is in the range of 5 to 80% by mass, and the window part comprises the polyethylene terephthalate resin, a polycarbonate resin or a polyphenylene ether resin as a constituting material.

  • Patent number: 6089937
    Abstract: Disclosed are a cathode-ray tube dividing apparatus and a cathode-ray tube dividing method intended to simply and stably divide a cathode-ray tube in a shortened time. The dividing apparatus includes a positioning means for fixedly positioning the used cathode-ray tube at a specific location, and a cathode-ray tube heating means which is brought into contact with a specific portion on side surfaces of the cathode-ray tube for linearly heating the specific portions. The cathode-ray tube heating means includes linear heating members for imparting thermal strain to the side surfaces of the cathode-ray tube upon receiving a power, thereby dividing the cathode-ray tube into the panel portion and the funnel portion, and a power supply for supplying a heating power to the linear heating members.

  • Patent number: 4354092
    Abstract: An electrically heated hair curling iron includes a sheet-shaped heater with electrodes affixed to an electrically resistive layer, wrapped around an elongated cylindrical support, and capable of being rapidly heated and maintained hot by electric current available from a rechargeable storage battery. The resistive layer has a positive temperature coefficient of resistance so that its temperature is self limiting. The storage battery is contained in a handle attached to the cylindrical support, and a battery charger is disclosed which comes into electrical contact with the battery when the handle is inserted in a cavity located in the battery charger. An elongated longitudinal clip is used to retain the hair in contact with the heater; a removable cap protects the heater and clip when the iron is not in use, and also engages a switch which ensures that the iron does not remain on.
