| 20100073796 | MAGNETIC FIELD SENSOR - A device for sensing a magnetic field is described. The device comprises first, second and third leads and a junction between the leads. The junction and leads are arranged in a plane and the junction is configured to exhibit quantum confinement in a direction perpendicular to the plane. The first lead is arranged on one side of the junction and the second and third leads are arranged on an opposite side of the junction. The first lead is configured to limit angle of spread of charge carriers entering the junction so that, when charge carriers flow into the junction from the first lead, the charge carriers form a substantially nondivergent beam. | 03-25-2010 |

| 20110000841 | Filter Cartridge and Method For Producing and Using Thereof - The group of inventions relates to liquid purifying devices and can be used for purifying drinking water and other liquids for household, medical and other purposes. A filter cartridge is filled with a filtering material and is configured in the form of an open bowl which can be closed with a lid, having side walls and a bottom with at least one outlet opening which is closed with a water-permeable material, wherein the cartridge bottom is designed such as to make it possible to use the water-permeable material which comes to the external edge of the side walls and is made of fibers with a sufficiently small diameter to allow using the filtering material containing powder particles; furthermore, the entire area between external and internal edges of the walls along the perimeter of the bottom is made of a composite based on a polymer water-permeable material. The method of producing the filtering cartridge involves placing a blank in at least a split mould, cutting it to the exact shape of a piece, filling a shaping cavity of the mould with a molted polymer material and extracting the product from the mould, wherein the cavity of the mould is filled with the molted polymer material upon placing the blank therein and the blank is cut up along a cutting zone which is formed in the purpose-made region of the mould. The filtering cartridge is used in a device for purifying liquid, substantially drinking water. | 01-06-2011 |

| 20090093868 | Laser Apparatus for Medical Treatment Using Pulse Trains - The present invention provides a laser apparatus for medical treatment using pulse trains, in which the skin is cooled to a given temperature and then one or more laser pulses are applied to a to-be-treated region at specific intervals, thereby alleviating a pain associated with a skin disease and activating a dermis layer. According to the present invention, a pain caused during the treatment process is alleviated by using laser pulse trains and a cooling unit, and heat energy is transferred to only a dermis layer of a to-be-treated region without eliminating an epidermis layer of the to-be-treated region, thereby remarkably improving the treatment recovery period and the frequency of treatments as compared to the conventional treatment method. | 04-09-2009 |
| 20100121418 | SKIN COOLING SYSTEM - The present invention provides a skin cooling system which can improve skin cooling efficiency and significantly reduce thermal damage and pain caused by heat generated during treatment, using a handpiece for injecting cold air, water, or a mixture of cold air and water. | 05-13-2010 |

| 20100150428 | METHOD AND APPARATUS FOR DETECTING MECHANICAL DEFECTS IN A SEMICONDUCTOR DEVICE, PARTICULARLY IN A SOLAR CELL ARRANGEMENT - A process detects defects in a semiconductor device, particularly a solar cell or solar cell arrangement, having at least one pn junction in a semiconductor layer of a semiconductor material with an indirect band junction. A voltage is applied to the at least one pn junction to operate it in the transmitting direction; and the radiation behavior of the semiconductor layer generated by the applied voltage, at least for partial ranges of the semiconductor layer, is optically detected and automatically examined for essentially one-dimensional intensity changes in order to detect mechanical defects. | 06-17-2010 |

| 20090107291 | Binder for the Fabrication of Diamond Tools - This invention relates to powder metallurgy, more specifically, to methods of fabricating hard alloy items. The invention can be used as an iron, cobalt or nickel base binder for the fabrication of diamond cutting tools for the construction industry and stone cutting, including segmented cutting discs of different designs and wires for reinforced concrete and asphalt cutting used in the renovation of highway pavements, runways in airports, upgrading of metallurgical plants, nuclear power plants, bridges and other structures, monolithic reinforced concrete cutting drills, as well as discs and wires for the quarry production of natural stone and large scale manufacturing of facing construction materials. This invention achieves the objective of providing binders for the fabrication of diamond tools having higher wear resistance without a significant increase in the sintering temperature, as well as higher hardness, strength and impact toughness. The achievement of these objectives by adding an iron group metal as the main component of the binder composition and alloying additives in the form of nanosized powder in accordance with this invention is illustrated with several examples of different type binders for the fabrication of diamond tools. | 04-30-2009 |
