The bus bar for wind turbine is shown with a symbolic break in its length and height as illustrated with the dash-dot broken lines. The appearance of any portion of the bus bar for wind turbine between the break lines forms no part of the claimed design. In the drawings, the evenly spaced broken lines illustrate portions of the bus bar for wind turbine which form no part of the claimed design.-

摘要： A flywheel system comprises a flywheel rotor comprising a rotor disc and a rotor shaft and has a longitudinal axis extending centrally through the rotor disc and the rotor shaft. The system further comprises a journal assembly configured to facilitate rotation of the flywheel rotor. The journal assembly comprises a sleeve having an aperture extending therethrough from a first end to a second, opposite end, a rod at least partially disposed within the aperture of the sleeve, and a nut coupled to a portion of the rod. The rod has a length greater than the sleeve such that a portion of the rod extends axially beyond the first end of the sleeve. A method of forming the flywheel comprises coupling the rod to the rotor shaft and pulling the second end of the rod to tension the rod. The nut maintains the tension in the rod when coupled thereto.

摘要： A voltage matched multijunction solar cell having first and second solar cell stacks that are electrically connected parallel to each other. The first solar cell stack is optimized for absorption of incoming solar light in a first wavelength range and the second solar cell stack is optimized for absorption of incoming solar light in a second wavelength range, wherein the first and the second wavelength range do not or at most only partially overlap each other.

摘要： A flywheel energy storage system incorporates various embodiments in design and processing to achieve a very high ratio of energy stored per unit cost. The system uses a high-strength steel rotor rotating in a vacuum envelope. The rotor has a geometry that ensures high yield strength throughout its cross-section using various low-cost quenched and tempered alloy steels. Low-cost is also achieved by forging the rotor in a single piece with integral shafts. A high energy density is achieved with adequate safety margins through a pre-conditioning treatment. The bearing and suspension system utilizes an electromagnet that off-loads the rotor allowing for the use of low-cost, conventional rolling contact bearings over an operating lifetime of several years.

摘要： A method for testing the die-attach quality of a photovoltaic cell assembly, in particular, for electrical inline monitoring of a photovoltaic cell die-attach quality during the manufacturing of a concentrator photovoltaic module, comprises the steps of providing a photovoltaic cell assembly comprising at least one photovoltaic cell, in particular, a concentrator photovoltaic cell, attached to a heat sink, injecting a current into the photovoltaic cell assembly, measuring the voltage across the photovoltaic cell during the current injection, and determining the relative voltage drop over the duration of the current injection, whereby insufficiently bonded photovoltaic cell assemblies can be identified and screened.
