An inexpensive rain water collecting device which is easy to manufacture. The rain water collecting device provides an effective device which is adaptable to various umbrella tip sizes and avoids any bacterial growth problems. The rain water collecting device includes at least a reservoir having a first open end and a second open end, the first open end has an opening with an inner perimeter which is substantially equal to an outer perimeter of the umbrella tip, and the second open end has an opening with a perimeter which is greater than the inner perimeter of the opening of the first open end; a ferrule formed about the opening of the first open end; and at least one flow barrier about the second open end of the reservoir. After using an umbrella in the rain, it is collapsed. The rain water on the cloth of the umbrella then drains into the reservoir of the rain water collecting device. The flow barrier(s) prevent the rain water contained in the reservoir from splashing out while the collapsed umbrella (although pointed substantially downward) is moved about.

Provided is a method of manufacturing a wire grid polarizer in which a stable color coordinate can be implemented. According to the present invention, in a process where a second grid pattern of metal pattern is formed over a first grid pattern made of resin material, metal layer is deposited in a concave portion formed between adjacent first grid patterns to form void portion and a width and a height of the second grid pattern are adjusted depending on adjustment of a width of the voids, and thereby improving a process efficiency.

The present invention relates to a wire grid polarizer capable of securing a high brightness and reducing the number of processes, a liquid crystal device including the wire grid polarizer, and a method of manufacturing the wire grid polarizer. According to the present invention, the wire grid polarizer, including first grids arranged in parallel at certain intervals over a substrate and second grids formed on the first grids, can be formed using only an imprint process, a deposition process, and a wet etch process. Accordingly, the number of processes and the process costs and time can be reduced, and high reliability can be guaranteed.

The present invention relates to a bone-regenerating composition containing angiogenin and to a bone-generating scaffold comprising the composition. Angiogenin has a superior ability to induce initial angiogenesis and bone regeneration as compared to the platelet rich plasma (PRP) which is used as a conventional element for stimulating bone regeneration, thus improving the speed of bone regeneration

The present invention relates to a bone marrow extractor. The bone marrow extractor of the present invention has an outer needle rod with a case having an upper portion and a lower portion in communication with each other. The case has a front end with a crushing blade and a rear portion with a stopper groove. An inner needle rod which has a main body having a front end with a crushing blade and a rear portion with a connector is inserted into the outer needle rod. The main body of the inner needle rod has an outer surface from which a stopper lever is protruded. The front end of the main body of the inner needle rod is protruded from the front end of the case of the outer needle rod when the stopper lever is fitted into the stopper groove. The inner needle rod and the outer needle rod cooperate with each other to crush bones through a rotation when the head of a driving means coupled to the connector operates. After bone crushing, only the inner needle rod is removed, and the outer needle rod is kept within the human body to suck and extract bone marrow in a syringe-like manner.
摘要:
A method of constructing an effective generator polynomial for error correction by which a unique set of syndromes for each error event is produced is provided. The method includes preparing a set of dominant error events from the intersymbol interference characteristics of media; and generating a codeword from the data using a non-primitive generator polynomial that produces a unique syndrome set which completely specifies each dominant error event.
摘要:
In an error correction method, a codeword is transmitted through a noisy communication channel and detected by a receiving device. An error detection code is then applied to the detected codeword to generate a syndrome. Where the syndrome is not all zero, the codeword is determined to contain some error. Accordingly, the method computes a set of potential error start positions for a plurality of error events based on a syndrome value corresponding to the syndrome. Next, a confidence value is computed for each of the plurality of error events at each of the potential error start positions in the refined set, and finally, a most likely error event in the detected codeword is corrected based on an error event and corresponding potential error start position having the highest confidence value.
