    摘要： A swing prism endoscope with adjustable viewing direction includes a shaft with a proximal end and a distal end and a window of a transparent material that seals an opening on the distal end of the shaft so that it is fluid-tight. In addition the swing prism endoscope includes a pivotable prism on the distal end of the shaft for adjustable diversion of light that falls through the window into the shaft of the swing prism endoscope onto an object lens, where the pivotable prism is made of diamond.

    摘要： A photoconductive composition useful for the preparation of printing plates is disclosed. The composition comprising an organic photoconductor, a charge carrier generating material, and a binder comprising a mixture of at least two copolymers. Copolymer (a) comprises an aromatic vinyl monomer, such as styrene or a substituted styrene, and maleic acid anhydride ring opened with a first aliphatic alcohol. Copolymer (b) comprises the following monomers: CH2═CH—(CH2)n—OR, in which n is 0 or 1, and R is selected from the group consisting of hydrogen, aliphatic groups having 1 to about 10 carbon atoms, and —COR′ in which R′ is an aliphatic group having 1 to about 10 carbon atoms, such as vinyl alcohol; maleic acid anhydride ring opened by a second aliphatic alcohol; and optionally CH2═CH—R″, in which R″ is a substituted or unsubstituted aromatic residue comprising from about 6 to about 20 ring atoms selected from the group consisting of carbon, oxygen, nitrogen, and sulfur, in which not more than 3 ring atoms are selected from the group consisting of oxygen, nitrogen and sulfur.
