    摘要: The invention provides a novel and efficient method for the elimination of protecting groups, e.g. benzyloxycarbonyl group, from a protected amino acid, peptide or derivative thereof having at least one functional group protected by a protecting group, e.g. a lower alkyl ester of N-benzyloxycarbonyl-.alpha.-L-aspartyl-L-phenylalanine by catalytic hydrogen reduction to produce free amino acid, peptide or derivative thereof. In contrast to the conventional procedures in which the reaction is carried out in a solvent dissolving both the starting compound and the product compound or a solvent dissolving the starting compound but not dissolving the product compound, the inventive method utilizes a binary two-phase reaction medium composed of water and an organic solvent not freely miscible with water such as toluene. The reaction takes place in the organic phase containing the starting compound dissolved and the catalyst dispersed therein whereas the reaction product which is water-soluble is smoothly and successively transferred into the aqueous phase so that advantages are obtained in the unexpectedly high yield of the product as well as in the easiness of handling the reaction mixture after completion of the reaction.

    摘要: The reaction between L-aspartic acid and benzyloxycarbonyl chloride is carried out at a specific pH range, i.e., 12.0 to 13.5, whereby highly pure N-benzyloxycarbonyl-L-aspartic acid can be obtained in high yields, while both the by-production of N-benzyloxycarbonyl-.alpha.- or .beta.-L-aspartyl-L-aspartic acid and the decomposition of benzyloxycarbonyl chloride to benzyl alcohol are suppressed.

    摘要: A liquid crystal display system which can accept display data having a resolution different from that of a screen for the liquid crystal display and display the display data. For example, a CPU outputs display data of 1120.times.780 dots and a liquid crystal panel has a 1024.times.768-dot resolution which is smaller than the display data resolution. The display screen of the liquid crystal panel comprises a linear arrangement of pixels. A data conversion section generates display data for a new horizontal or vertical line based on display data for two horizontal or vertical lines contiguous to each other and repeats replacement of display data of the two lines with the display data of the one line for reducing the number of horizontal lines of one screen and the number of dots of one line so as to match the resolution of the display data output by the CPU with the liquid crystal display. In contrast, if the resolution of the display data is smaller than the screen resolution of the liquid crystal panel, the data conversion section inserts the display data of the new one horizontal or vertical line between the two contiguous lines for enlarging the resolution of the display data.

    摘要: An apparatus and method for separating the design and implementation of a user interface ("the user interface logic") from the design and implementation of the functional portion of a software program (the "core logic"). The present invention uses an object-oriented programming model in which one or more look and feel agents act as servers for one or more logic objects. The look and feel agent controls the appearance and behavior of the user interface, while a logic objects perform the functions of the software program. A look and feel agent does not "know" what functions constitute the core logic and the logic objects do not "know" what the user interface looks like or how it behaves.
