In a method of designing a semiconductor device, a transistor included in a layout of the semiconductor device may be selected. A biasing data may be set for changing a characteristic of the selected transistor. A design rule check (DRC) process for the layout of the semiconductor device may be performed after ignoring the biasing data. An optical proximity correction (OPC) process for the layout of the semiconductor device may be performed based on the biasing data.

The invention provides a segment type diamond tool capable of improving cutting rate and reducing the amount of fine debris generated during cutting by properly arranging diamond particles in a cutting segment of the diamond tool. In the invention, the layers of diamond particles are arranged such that cutting grooves formed on a workpiece by trailing layers of diamond particles are arranged between cutting grooves formed thereon by leading layers of diamond particles, respectively, in cutting of the work piece. The cutting segment has high-concentration and low-concentration areas. The high-concentration area shows a concentration higher than an average concentration and the low concentration area shows a concentration lower than the average concentration. Also, at least one low concentration area is formed on the leading and/or trailing section of the cutting segment. The diamond tool of the invention ensures superior cutting rate and reduced amount of fine debris generated during cutting.

The present invention relates to a power factor compensation device for a motor driving inverter which can improve a power factor of a voltage and a current inputted to the inverter driving a motor. The present invention detects a zero crossing point of an utility alternating current power, and outputs a driving signal corresponding to a plurality of sine wave form voltage values stored in a memory according to a detection result, when the zero crossing point of the utility alternating current power is detected in a state where the plurality of sine wave form voltage values corresponding to a voltage of the utility alternating current power and frequencies are stored in the memory. A switching transistor is switched according to the driving signal, and the voltage applied to the inverter is switched according to the switching operation, thereby improving the power factor.

A method for manufacturing a cold rolled steel sheet for use in a shadow mask is disclosed, in which without adding an expensive alloy element, a short intermediate decarburization annealing is carried out, and despite this fact, a forming defect does not occur after the forthcoming stacked annealing. The method includes the steps of preparing a steel composed of, in weight %, 0.003% or less of C, 0.10-0.20% of Mn, 0.01-0.05% of Al, 0.004% or less of N, and a balance of Fe and other unavoidable impurities. A hot rolling is carried out on the steel at a temperature of above 910° C., and then, a first cold rolling is carried out to form a first cold rolled steel sheet. Then a decarburization is carried out on the first cold rolled steel sheet down to a carbon content of 0.0015% to form a decarburized steel sheet, and then a second cold rolling with a reduction ratio of more than 35% is carried out on the decarburized steel sheet.

摘要:
Systems and methods related to optical nanosensors comprising photoluminescent nanostructures are generally described. Generally, the nanosensors comprise a photoluminescent nanostructure and a polymer that interacts with the photoluminescent nanostructure. In some cases, the interaction between the polymer and the nanostructure can be non-covalent (e.g., via van der Waals interactions). The nanosensors comprising a polymer and a photoluminescent nanostructure may be particularly useful in determining the presence and/or concentration of relatively small molecules, in some embodiments. In addition, in some instances the nanosensors may be capable of determining relatively low concentrations of analytes, in some cases determining as little as a single molecule. In some embodiments, the interaction between the analyte and the nanosensor (e.g., between the analyte and the photoluminescent nanostructure) can be reversible, which may allow, for example, for the reuse of a nanosensor after it has been exposed to an analyte.

A cutting segment of a cutting tool for cutting or drilling a brittle work piece such as stone, bricks, concrete and asphalt, and a cutting tool. The cutting segment includes a cutting surface for cutting a work piece and a number of abrasive particles arranged in a plurality of rows. Each of the abrasive rows includes high-concentration parts and low-concentration parts. The high-concentration parts are grouped together to form a high-concentration area on the cutting surface and the low-concentration parts are grouped together to form a low-concentration area on the cutting surface. The cutting segment and the cutting tool are capable of improving cutting rate and useful life.
