Abstract: In an ion implantation apparatus which is for use in injecting an ion beam (11) onto a wafer (12) in a predetermined direction and which comprises an electric conductor tube (14) divided into a first tube section (17) and a second tube section (18) along the predetermined direction with an insulator interposed therebetween. The first tube section is located in proximity of the wafer and is grounded while the second tube section is remote from the wafer to be used as a target section which is bombarded by primary electrons to generate secondary electrons directed to the wafer. Undesired electrons are trapped by the first tube section and flow through the ground. The electric conductor tube may further comprise a third tube section (21) which is electrically insulated from the second tube section and which is remote from the wafer in comparison with the second tube section in the predetermined direction. The first and the third tube sections are controlled so as to adjust their diameters in dependency upon a diameter of the ion beam.

Abstract: A process is described for the separation and recovery of isocyanate monomers from isocyanate concentrates which leaves a residue which is liquid and burnable. The process for the separation and recovery of isocyanate monomers from isocyanate concentrates formed in the production of isocyanates and comprising a volatile isocyanate monomer and by-products comprises the steps of: (A) preparing a mixture comprising (A-1) the isocyanate concentrate; and (A-2) an oil solution comprising; (A-2-a) a major amount of hydrocarbon oil, and (A-2-b) a minor amount of at least one ashless dispersant; and (B) heating the mixture to an elevated temperature at reduced pressure whereby isocyanate monomer is distilled and recovered leaving a liquid residue. The presence of the oil solution in the mixture facilitates the distillation of the isocyanate concentrate, generally improves the yield of distilled isocyanate monomer, results in a residue which is liquid and easily removed from the distillation apparatus, and the liquid residue can generally be burned without difficulty.
