This invention provides a knitted slide fastener, wherein at least a part of a base structure composing respective wales (W11 to W13) of a fastener element attaching portion (EF) of a fastener tape includes a ground chain knitting yarn composed of a single structure, and a partial needle loop of a fixing chain knitting yarn composes a double base structure while being interlaced only with the needle loop of the ground chain knitting yarn of the second wale (W12), the partial needle loop of a fixing chain knitting yarn to be formed on at least the second wale (W12) at a second row from the side nearest to a coupling head portion (EH) of the fastener element attaching portion (EF) among the three or more fixing chain knitting yarns of the fastener element attaching portion (EF), the knitted slide fastener being organized at a high speed with few kinds of stitches without an excess load on a needle, an element being solidly fixed.

A facing laminate for insulation products includes: a foil or metallized polymeric film sheet layer forming an inner layer of the laminate that is adapted be bonded directly to a surface of an insulation product; a paper composite sheet layer, which may include synthetic and / or inorganic fibers, forming an outer exposed layer of the laminate; and a scrim intermediate and bonded to the foil or metallized polymeric film sheet and paper composite sheet layers. The facing laminate may include a humectant and / or a water, oil, and / or grease repellant component. The paper composite sheet layer of the laminate exhibits greater dimensional stability and reduced wrinkling when the laminate is exposed to conditions of high humidity. Insulation products to be faced with this facing laminate include pipe insulation, duct board, duct wrap insulation, metal building insulation, and other building insulation products.

The purpose of this invention is to provide an ultra-miniature aircraft which is able to perform ‘Vertical Take-off and Landing (VTOL)’ and maintaining altitude when the vehicle is moving or when the horizontal velocity of a vehicle is at 0 by getting life only from a single rotor's rotation, and without using separate stabilizers such as a tail-rotor or a gyro. To fulfill the above purpose, this invention comprises: several blades in airfoil shape that are places in calculated angle and space; hubs that connect the blade to with a body of a vehicle; a rotor which gives lifting force with its spin; a spin-able axle which its vertical hem is bound to the hubs; a rotor drive that is needed to spin the rotor; a vehicle body that is placed right under the rotor in order to fly from the lift that is obtained by revolutions of the rotor; fixed-wings that are placed in certain angle and space around the outside of the vehicle body in order to reduce a reaction torque, which affects the body to turn the opposite direction of the rotor, from the rotor's movement; and a reaction-torque-counterbalancing-system on each of the above fixed-wings that offsets the reaction torque aggressively.

A rotor that includes an impeller secured to a shaft. The impeller has a bore and a counterbore. The shaft forms an interference fit with the bore and is adhered to the counterbore. A method of manufacturing the rotor is also described.

Method and controller device for controlling a plurality of N transport paths in RANs, wherein a primary path is assigned for each type of traffic to allocate voice or data calls, comprising:measuring load of the primary path periodically,when a call is incoming, comparing the measured load with a threshold,if the load of the primary path is less than or equal to the threshold, allocating the call to the primary pathotherwise:calculating the available bandwidth of each transport path;comparing the available bandwidth of the primary path to the available bandwidths of the other transport paths and:if the available bandwidth of the primary path is greater than or equal to the available bandwidths of the others, allocating this call to the primary path;otherwise, allocating the call to a secondary path chosen from the remaining N−1 transport paths.

A split axis stage architecture is implemented as a multiple stage positioning system that is capable of vibrationally and thermally stable material transport at high speed and rates of acceleration. A split axis design decouples stage motion along two perpendicular axes lying in separate, parallel planes. A dimensionally stable substrate in the form of a granite, or other stone slab, or of ceramic material or cast iron, is used as the base for lower and upper stages. The substrate is precisely cut (“lapped”) such that its upper and lower stage surface portions are flat and parallel to each other.

The object of the present invention is to provide a nonaqueous electrolyte secondary battery which has excellent balance of general performance with respect to performance including durability, capacity, resistance, and output characteristics. Provided is a nonaqueous electrolyte battery comprising a positive electrode and a negative electrode each being capable of occluding and releasing metal ions, and a nonaqueous electrolyte solution, wherein the nonaqueous electrolyte solution contains an electrolyte, a nonaqueous solvent, and at least one compound selected from the group consisting of a compound having a fluorosulfonyl structure (—SO2F), a difluorophosphate, and an isocyanate compound, and wherein the negative electrode has a negative electrode active material containing metal particles capable of alloying with Li and graphite particles.
