  • Patent number: 5648233
    Abstract: Modified TCF in which one or more amino-acid residues of the wild type TCF responsible for glycosylation are substituted or deleted so that at least one N-linked oligosaccharide chain is removed. The modified TCFs have a longer biological half-lives without loss of their biological activities. The modified TCFs are therapeutically important as agents for liver diseases or as anti-cancer drugs.

  • Patent number: 5300184
    Abstract: A press roll apparatus temporarily or finally bonds two glass sheets with an adhesive intermediate film sandwiched therebetween to manufacture a laminated glass. The press roll apparatus has a plurality of drive roll units each having a pair of upper and lower presser rolls operatively coupled to a drive source and rotatable thereby for pressing the glass sheets therebetween, and a plurality of free roll units each having a pair of upper and lower presser rolls freely rotatable for pressing the glass sheets therebetween. The drive roll units and the free roll units are housed in a frame and vertically positionally adjustably supported by the frame, the frame having a pair of horizontal shafts projecting outwardly. The frame is supported on a support frame by the horizontal shafts for angular movement about the horizontal shafts, the support frame having a pair of horizontally spaced vertical support columns.

  • Patent number: 4863340
    Abstract: An automatic loading system includes an automatic loading apparatus for automatically loading, onto a pallet, a glass sheet product as it lies substantially horizontally and is delivered along a feed path to a terminal position of the feed path. The automatic loading apparatus has a suction mechanism for attracting the lower surface of the glass sheet product at the terminal position and for moving the glass sheet product to a loading position to load the glass sheet product onto the pallet. The automatic loading system also includes an apparatus for putting an interleaving sheet on an upper surface of the glass sheet product in the feed path. The interleaving sheet putting apparatus comprises a mechanism for moving an uppermost interleaving sheet of a stack of interleaving sheets over the glass sheet product, and a holder mechanism for holding the uppermost interleaving sheet against an upper surface of the glass sheet product.

  • Patent number: 4285716
    Abstract: While a heated glass sheet moves through a quenching section, the glass sheet is blown with air in the same portions so as to be quenched always in the same portions to provide on the glass surface rapidly cooled portions and uncooled portions. Thereby the residual strains on the glass surface are made different to prevent the generation of pieces or splines when the glass sheet is broken.
