A Mixer / Ejector Wind Turbine (“MEWT”) system is disclosed which routinely exceeds the efficiencies of prior wind turbines. In the preferred embodiment, Applicants' MEWT incorporates advanced flow mixing technology, ejector technology, aircraft and propulsion aerodynamics and noise abatement technologies in a unique manner to fluid-dynamically improve the operational effectiveness and efficiency of prior wind turbines, so that its operating efficiency routinely exceeds the Betz limit. Applicants' preferred MEWT embodiment comprises: a turbine shroud with a flared inlet; a ring of stator vanes; a ring of rotating blades (i.e., an impeller) in line with the stator vanes; and a mixer / ejector pump to increase the flow volume through the turbine while rapidly mixing the low energy turbine exit flow with high energy bypass wind flow. Unlike gas turbine mixers and ejectors which also mix with hot core exhaust gases, Applicants' preferred apparatus mixes only two air streams (i.e., wind): a primary air stream which rotates, and transfers energy to, the impeller while passing through the turbine; and a high energy bypass flow or “secondary” air stream which is entrained into the ejector, where the secondary air stream mixes with, and transfers energy to, the primary air stream. The MEWT can produce three or more time the power of its un-shrouded counterparts for the same frontal area, and can increase the productivity of wind farms by a factor of two or more. The same MEWT is safer and quieter providing improved wind turbine options for populated areas.

The present invention relates to an optical film for a backlight unit and a method for manufacturing the same. The optical film of the present invention comprises a light diffusion layer in which light diffusing particles are distributed, a first refraction layer which has a relatively low index of refraction and is formed integrally on a top surface of the light diffusion layer, and a second refraction layer which has an index of refraction relatively higher than that of the first refraction layer and is formed integrally on a top surface of the first refraction layer and formed with a refraction pattern on a surface thereof. According to the present invention, the loss of light can be prevented, the adsorption of foreign substances in and the resultant scratch generation on the films can be avoided during the assembly process of the backlight unit, the productivity improvement and manufacturing cost reduction can be achieved, and the brightness of the backlight unit can be adjusted.

A method of manufacturing a resin bag whereby the peripheral edge of the bag such as a resin air baa is not bulky, the bonding strength is still sufficient, and the productivity is increased, is provided. A first resin sheet 1 and a heat-resisting sheet 3 are overlaid on each other and are disposed in a cavity 13 of a mold 7. The diameter of the heat-resisting sheet 3 is smaller than that of the first resin sheet 1 so that a portion of the sheet 1 is exposed outside the heat-resisting sheet 3. After injecting resin 2' into the cavity 13 through a sprue bush end 12, the resin 2'is pressed and expanded to mold a second resin sheet 2 and bond the sheet 2 to the sheet 1 at the peripheries thereof.

To provide a bearing assembly having a temperature sensor built therein, in which the accuracy of detection of the abnormal temperature is increased, the number of component parts is reduced and the productivity can be increased, a rolling bearing assembly (1) includes a sealing member (7) secured to a stationary bearing ring and a temperature sensor (13) is secured to the sealing member (7). The stationary bearing ring is an inner race (2) if the bearing assembly (1) is of an outer race rotating type. The sealing member (7) is made up of a core metal 9 and an elastic member (10) made of a rubber or resin. The temperature sensor (13) is fixed to the core metal (9) of the sealing member (7) either by means of an insert molding of the elastic member (10) or soldering after forming the sealing member (7). The temperature sensor (13) is in the form of a chip-type laminar thermistor.

A method and apparatus for cell harvest of production scale quantities of cell cultures using single use components comprising a flexible membrane mounted on a rigid frame and is supported within a multiple use rigid centrifuge bowl, such single use components including a core with an increased diameter and an internal truncated cone shape in order to permit the system to maintain a sufficiently high angular velocity to create a settling velocity suited to efficiently processing highly concentrated cell culture streams. Features which minimize feed turbidity, and others which permit the continuous or semi-continuous discharge of cell concentrate, increase the overall production rate over the rate which can be achieved using current intermittent processing methods for large cell culture volumes. Injection of a diluent during the cell concentrate removal process permits more complete removal of viscous cell concentrates.

The aspherical lens constructed by a substrate member A and a member B having different composition formed on the substrate member A. A boundary between the substrate member A and the member B having different composition is formed by a first aspherical surface RAB, and a surface of the member B having different composition opposite to the boundary being formed by a second aspherical surface RB having higher fabrication accuracy than that of the first aspherical surface RAB, and given conditional expressions are satisfied.

A semiconductor defect inspection device and method for detecting defects of partially finished substrates (semiconductor wafers) for semiconductor devices is provided. The substrate surface is irradiated with a charged particle beam and a voltage contrast image is obtained while the charged voltage is controlled at a desired level, and the electric resistances of the irradiated area from the image are calculated to detect a defect and identify the type of defect. Further, the distribution of electric resistances on the whole surface of the substrate can be quickly worked out. The charged particle beam irradiation conditions are varied in order to bring the charged voltage of the area to a desired value. With this device / method, electric resistances of small portions at desired charged voltages and the corresponding electric resistances are measured in a non-contact manner to determine the type of defect. When this inspection method is applied to the PCB manufacturing process, defects can be detected and remedied at an early stage of the process. Consequently, in the semiconductor devices and other PCB related devices, the defect rate decreases and the productivity increase. Since the defect occurrence rate is reduced, the reliability of semiconductor devices is increased, and the efficiency in developing new products is improved.

The method of wells production rate increase which includes lowering the hydroperforator equipped with hydromonitor nozzles into the well on the pipe string; pumping liquid with abrasive material under pressure into the pipe string and hydroperforator; impacting the well elements and the stratum with the liquid with abrasive material via hydroperforator hydromonitor nozzles. When liquid with abrasive material impacts the well elements and the stratum, pressure is changed in the pipe string delivering the liquid with abrasive material. The difference is that pressure is changed over time so that pressure oscillations always include components with different frequencies, and in doing so, peak values (amplitudes) for at least some pressure oscillation components vary within the time interval Td, where Td≦Tv; Tv being the time of impact of the liquid with abrasive material on the well elements and the stratum via hydroperforator hydromonitor nozzles.
