A pumped storage facility combined with at least a seating area constructed on a bank of an upper reservoir facing a lower reservoir. The lower reservoir includes a track around the shore thereof so that spectators in the seating area can view the track. A performance area is constructed adjacent the track along the lower reservoir, and can be built over the water on piers if needed. Thus, racing events can take place on the track and be viewed by spectators in the seating area. A parking lot drains water into the lower reservoir.

The invention is based on the discovery that modified calcium carbonates can be used as fillers for the preparation of non-abrasive adhesive formulations that are useful in microelectronic applications. The modified calcium carbonate fillers possess functional groups, which form strong bonds to the thermoset matrix. Invention compositions display excellent rheological properties, in addition to a low coefficient of thermal expansion.

The invention discloses a metal fiber brush and a preparation method thereof. The brush comprises conductive metal fibers and filling metal fibers. The length of the filling metal fibers is shorter than the length of the conductive metal fibers, one end of each filling metal fiber is flush with one end of each conductive metal fiber, the conductive metal fibers and the filling metal fibers are uniformly arranged along a length direction, and after compacting molding, the filling metal fibers and the conductive metal fibers are integrally wrapped by a metal wrapping sleeve. The preparation method comprises: winding the conductive metal fibers and the filling metal fibers together on a wire reel to form a metal fiber ring; and cutting the metal fiber ring, after the compacting molding, immersing one end of the metal fiber ring in an acid solution or aqueous alkali, and dissolving the filling metal fibers to obtain the metal fiber brush. The metal fiber brush is compact and reasonable in structure, high in fiber bonding strength, simple in preparation process, large in current carrying capability, small in contact resistance, long in service life, fast in sliding speed, small in heat productivity and small in debris amount, is suitable for industrial production, can replace a conventional carbon brush or a conventional metal fiber brush, and can satisfy the application demand for a large-power high-precision conductive slip ring.

The invention provides a light stone-imitating particulate matter and a water-based stone-imitating coating prepared by adopting same, and belongs to the technical field of water-based architectural coatings. The preparation method comprises the following steps: smashing or cutting waste or a leftover material of rubber, resin and engineering plastics or reclaimed rubber into particles, coating a colored film on the surface to prepare the light stone-imitating particulate matter. The water-based stone-imitating coating prepared by adopting the stone-imitating particulate matter comprises the following ingredients in percentage by weight: 8-30% of emulsion, 30-80% of a light stone-imitating particulate matter, 1-40% of an inorganic pigment filler, 1-8% of a wetting dispersant, 0.5-8% of a thickening agent, 0.1-5% of an antifoaming agent, 0.5-5% of a film coalescing aid, 0.1-1% of a mildew inhibitor, 1-10% of an anti-freezing agent, and proper amount of water, wherein the pH value is regulated to be 8-9.5 with a pH regulator. The imitated stone is life-like, and presents strong artistic feeling. As the specific weight of the light stone-imitating particulate matter is low, the flexibility is good, and the abrasiveness to a mixing plant is low; a lot of thickening agents or anti-setting agents are not required to be added, and the prepared stone-imitating coating has high stability, long storage life, and convenience in construction. Moreover, the technology avoids black pollution such as waste tires, and is beneficial to environment protection.
