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.

Shell material for recording media

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. The power supply is adapted to supply a first power for generating cracks on the side surfaces of the cathode-ray tube to the linear heating members, and to supply, after generation of the cracks, a second power larger than the first power to the linear heating members.
