Abstract: Disclosed is a continuous process for the production of optically pure (S)-β-hydroxy-γ-butyrolactone having constantly maintained optical activity, consisting of hydrogenating 2-50 wt % of a substituted carboxylic acid derivative in a solvent using a fixed bed reactor filled with a precious metal catalyst-impregnated inorganic oxide carrier at 50-500° C. under pressure of 15-5,500 psig at weight-space-velocity of 0.1-10 h−1, in which a molar ratio of hydrogen to carboxylic acid derivative ranges from 2 to 10. The desired material can be produced in higher optical purity and at higher yield by the current process which is relatively simpler and environmentally safer than conventional processes. Additionally, increased production efficiency leads to production of the desired material on a large scale.

Abstract: A hinge apparatus includes a substantially cylindrical holder having at least one guide hole with a predetermined degree slope that extends in a longitudinal direction. A hinge shaft includes a substantially cylindrical surface configured to linearly move in the longitudinal direction of the holder. A guide pin has an end located inside the guide hole and is configured to extend through the cylindrical surface of the hinge shaft. Therefore, when the hinge shaft moves linearly in the holder, the guide pin moves along the guide hole so that the hinge shaft rotates in the holder.

Abstract: A circuit conveniently sets the width of input/output data in a semiconductor memory device. The circuit includes a test mode signal generator for generating a test mode signal which sets a WCBR mode to a special test mode; a program signal generator for generating a program signal according to the test mode signal output from the test mode signal generator and a signal transmitted through a predetermined address line; a pair of anti-fuse programmers, each having an anti-fuse for outputting a programmed output value indicative of a program status of an anti-fuse programmed according to the program signal; and a decoder for decoding the signal output from the anti-fuse programmers to change the input/output data width of the semiconductor memory device. The anti-fuses are used for resetting the input/output data width at the package level of a manufactured memory device. The decoder generates a first signal for setting an input/output data width at eight bits, if a signal input through the predetermined address line is toggled once, and generates a second signal for setting the input/output data width at four bits, if the signal input through the predetermined address line is toggled once more.
