摘要:
Disclosed are a lyocell filament fiber and a cellulose-based tire cord. The lyocell filament fibers and the cellulose based tire cord have good dimensional stability in a highly humid state and thus the tenacity, the elongation, and the modulus are superior to common cellulose based fibers, such as rayon and so on. Their property maintaining rate at the post manufacturing process is high and the processibility is good.

Compact cosmetic case with airtight sealed structure, which has a simple construction and enhances its airtight sealed effect to prevent a leakage of cosmetics, such as powder, thus improving quality, increasing productivity and reducing the production costs. The compact cosmetic case includes a body, an inner casing to contain the powder, an inner lid hinged the inner casing and having a powder puff seat, and an outer lid hinged to the body and having a locking part. A groove is formed around an upper surface of the inner casing, with liquid rubber filling the groove to form a rubber seal. A locking hole is formed on the inner casing, while a locking lever having a locking projection is formed on the inner lid to be locked to the locking hole.

A method and system for improving a channel change rate using a conditional access table/program map table (CAT/PMT) to be transmitted in an out-of-band (OOB) band. First main data including a channel ID of a scrambled channel and Conditional access table (CAT) information corresponding thereto and defining a version is transmitted from a main program of a conditional access system (CAS) headend. Second main data including the channel ID and Program map table (PMT) information corresponding thereto and defining a version is transmitted from a main program of a demux/remux device. Third main data generated by receiving and combining the first and second main data is included in service information (SI) and is transmitted in an Out-of-band (OOB) band. After extracting only the third main data from the transmitted Service information (SI) in response to a channel change event signal, encrypted broadcast content of each channel is released and provided to a user.

A flexible PCB is provided with surplus bends so that it can be readily bent according to the repetitive movement thereof, whereby wires formed in the flexible PCB can be prevented from being severed by the bending fatigue accumulated due to the movement. The flexible PCB for use in electronic equipment acts to transmit electrical signals between two rigid PCBs and acts as a structural bridge therebetween, the two rigid PCBs being spaced away from each other and being able to relatively move. The flexible PCB includes: a plurality of wires, each functioning as a passageway for electrical signals; and a soft material-based substrate body in which the wires are formed; and being provided with surplus bends at predetermined positions so as to allow the flexible PCB to resiliently move according to the relative movement of the rigid PCBs.

The present invention discloses a method for improving uniformity and alignment accuracy of contact hole array pattern. A dummy mask pattern is added to adjacent to contact hole array mask pattern during a design of an exposure mask to maintain a uniformity of contact hole size and prevent contact hole size error and shift of the contact hole pattern.

A stacked chip package includes a substrate having an upper surface and a lower surface, a first semiconductor chip having an upper surface and a lower surface, wherein the lower surface of the first semiconductor chip is attached to the upper surface of the substrate and the upper surface of the first semiconductor chip includes a plurality of first electrode pads, and a second semiconductor chip having an upper surface and a lower surface. The lower surface of the second semiconductor chip is attached to the upper surface of the first semiconductor chip, and the lower surface of the second semiconductor chip includes trenches that correspond to the locations of the first electrode pads on the upper surface of the first semiconductor chip.
摘要:
A method of partially oxidizing an alcohol to an aldehyde or ketone comprises contacting a gas containing the alcohol with a solid catalyst containing molybdenum, preferably in a +6 oxidation state, and having a surface area of 10 m2/g or higher, preferably 100 m2/g or higher. The molybdenum is supported on a high surface area carrier. The alcohol is a primary or secondary alcohol and preferably contains from 1 to 6 carbon atoms. In a preferred embodiment, the alcohol is ethanol. NOx emissions from an internal combustion engine can be lowered by combining the product of partial oxidation with the exhaust stream before passing the exhaust mixture through a lean NOx catalyst. The partial oxidation product may be generated on board and injected into the exhaust under closed loop or open loop control
摘要:
The present invention relates to a novel polymer, an adhesive composition including the same, and a rubber reinforcing material treated with the same, and more particularly to an organic polysiloxane including a certain repeating unit, an adhesive composition including the same, and a rubber reinforcing material treated with the same.Because the organic polysiloxane and the adhesive composition including the same is superior in reactivity to a hydroxyl group, an amide group, or an amine group, and has high thermal resistance and low stiffness, the composition is preferably used for surface-treating a rubber reinforcing material such as a tire cord and make it possible to provide a rubber reinforcing material such as a tire cord having good properties.
