  • Patent number: 5474617
    Abstract: A method for regenerating an image holding-supporting member has the steps of impregnating the image holding-supporting member with a liquid including at least water molecules; the image holding-supporting member having a chartaceous material constructed by cellulose as a principal component and having a hydrophobic image formed on this chartaceous material; and separating the hydrophobic image from the chartaceous material by an image separator in an impregnating state of the liquid so that an image can be recopied and reprinted on the chartaceous material. In accordance with this reproducing method, a copy is made or a sheet of printing paper is regenerated by cleanings of a PPC copying image and a PPC printing image normally utilized in markets at present in addition to cleaning of images copied and printed on sheets of special paper such as erasable paper so that the image holding-supporting member can be reused as a paper sheet for copying or printing.

  • Patent number: 5032055
    Abstract: Supplying and receiving devices for carriers, which carry substrates for semiconductors thereon, including a pair of carrier guides with an open space; carrier holding claws pivotally provided on the carrier guides so that the claws can hold a carrier; a carrier lifter which moves up and down between the carrier guides; and claw opening pieces provided on the carrier lifter. In the carrier supplying device, the carrier lifter moves up and when the claw opening pieces come into contact with the claws and open the claws. The lowermost carrier accommodated in the carrier guides is then released from the claws and placed on the carrier lifter so that the carrier is taken out of the carrier guides and the carrier immediately above the released carrier is held by the claws.
