摘要:
An apparatus for use with an elevator car is operable to selectively lock an elevator car door. The apparatus verifies that the elevator car door is closed, locks the elevator car door, and verifies that a lock is engaged. Once conditions are met, the apparatus signals an elevator controller that the elevator car can move through a hoistway. The apparatus further ensures that passengers can safely disembark from the elevator car by detecting the position of the elevator car relative to a designated landing zone within the hoistway, and confirming the elevator car is stopped at a landing zone prior to disengaging the lock. The apparatus thus ensures that the elevator car door remains closed while the elevator car is in motion or between landing zones.

A method of making a finely textured molded article is disclosed. The method utilizes properties of the compound being molded, such as impact toughness and melt flow index. Poly(vinyl halide), particularly poly(vinyl chloride), articles can be compound-injection-molded using the method, in order to simulate the appearance of original metal, glass, or wood articles. Consumer, transportation, building construction, and other industries can benefit from durable plastic articles that simulate the more fragile articles.

A coil nailing device for finishing materials is invented that comprises a standby part for temporarily retaining and loading the nails into a muzzle. A door is installed adjacent to the standby part to check the nail supply. A door latch consists of a hook, coil spring and latch hinge shaft. The door and door latch are operated in the lateral direction, perpendicular to the axis of the main body. The muzzle consists of an adapter, lever arm and a pair of arc-shaped sliding grooves formed on both lateral surfaces. The adapter is attachable to the nose of the main body. A clearance setting device is designed to allow the use of various sizes of nails by setting the depth of the magazine depending on the loaded nail size. An interval setting device is convenient to nail a series of shingle panels by setting the panel interval while the coil nailing device is sliding along the edge of the panels.

A portable microwave plasma discharge unit receives microwaves and a gas flow via a supply line. The portable microwave plasma discharge unit generates plasma from the gas flow and the received microwaves. The portable microwave plasma discharge unit includes a gas flow tube made of a conducting and/or dielectric material and a rod-shaped conductor that is axially disposed in the gas flow tube. The rod-shaped conductor has an end configured to contact a microwave supply conductor of the supply line to receive microwaves and a tapered tip positioned adjacent the outlet portion of the gas flow tube. The tapered tip is configured to focus the microwaves received from the microwave supply conductor to generate plasma from the gas flow.

A method for developing a culture medium using genome information and in silico anlaylsis. In one implementation, the method involves developing a minimal synthetic medium, including the steps of constructing a metabolic network using genome information of prokaryotic cell or eukaryotic cell, selecting components of the minimal synthetic medium removing any one among external metabolites from the constructed metabolic network and conducting metabolic flux analysis using in silico simulation, and determining a final culture medium by actual culture.

A semiconductor device includes a device isolation structure formed on a semiconductor substrate to define an active region. A first Si-based epitaxial pattern is formed over the active region corresponding to a bit line contact region and a portion of a gate region at both sides adjacent to the bit line contact region. A second Si-based epitaxial layer is formed over the semiconductor substrate which is stepped up on the first Si-based epitaxial pattern. A stepped gate pattern is formed over the stepped second Si-based epitaxial layer.

The semiconductor device includes an active region, a stepped recess channel region including vertical channel structures, a gate insulating film, and a gate structure. The active region is defined by a device isolation structure formed in a semiconductor substrate. The stepped recess channel region is formed in the active region. The vertical silicon-on-insulator (SOI) channel structures are disposed at sidewalls of both device isolation structures in a longitudinal direction of a gate region. The gate insulating film is disposed over the active region including the stepped recess channel region. The gate structure is disposed over the stepped recess channel region of the gate region.
摘要:
The present invention relates to a composition for the prevention and treatment of diabetic complications, which contains an extract obtained by: crushing and drying any one selected from Euphorbiae radix, gingered Magnolia bark, parched Puerariae radix and Glycyrrhizae radix; extracting the dried herbal material with alcohol or aqueous alcohol solution: filtering the extract; and concentrating the filtrate under reduced pressure. Alternatively, the composition contains a mixture of extracts from Euphorbiae radix, gingered Magnolia bark, parched Puerariae radix and Glycyrrhizae radix, the amount of each of the herbal extracts being 5-85% by weight based on 100% by weight of the herbal extract mixture. Alternatively, the composition contains magnolol obtained by: extracting Magnolia bark with aqueous 80% ethanol solution at ambient temperature for 24 hours; systematically separating the extract in the order of normal-hexane, ethyl acetate and normal-butanol; selecting the normal-hexane layer and separating the selected layer into pre-fractions by normal silica gel chromatography; comparing the pre-fractions with the standard form magnolol on TLC to determine a magnolol-enriched fraction; and separating magnolol from the magnolol-enriched fraction by silica gel column chromatography.
