Abstract:
A wave power generation device, including a power generation assembly, a mooring system, a floating platform, floating towers, control cabins, a connecting member, and anti-sway plates. The floating platform is a square floating box. The power generation assembly includes a swing plate, a hydraulic cylinder, an energy accumulator, a hydraulic motor, a generator, a battery, and a power generation and distribution device. The floating platform includes a main deck. The main deck includes a manhole and a support for supporting the swing plate. The swing plate is connected to the support via a first hinge. One end of the hydraulic cylinder is connected to the swing plate, and another end of the hydraulic cylinder is connected to a floating platform. The mooring system includes four anchor windlasses. A method for operating and maintaining the wave power generation device is also provided.
Abstract:
Quaternary ammonium bicarbonates are suitable for use as latent catalysts in curable epoxy compositions. The curable compositions prepared therefrom are used to prepare coated substrates, and to produce conformally sealed printed wiring boards and flexible circuits. Method for preparation and curing are also provided. Of particular utility are compositions comprising benzyltrimethyl ammonium bicarbonate. The curable epoxy composition is coated onto a substrate such as a film or sheet, to form a coated article. The cure of the epoxy can be advanced after coating.
Abstract:
A ventilation apparatus with a two-section feedback compensation control and a method for operating the same are disclosed. The ventilation apparatus includes a power conversion trait (10), a driven circuit (20), a DC motor (30), a current-sensing unit (40), a voltage compensation unit (60), and a control unit (50). The power conversion unit (10) receives and converts an AC power voltage (Vac) into a DC power voltage (Vo). The driven circuit (20) receives the DC power voltage (Vo) and outputs a driven voltage. The DC motor (30) is driven through the driven voltage. The current-sensing unit (40) senses an output current of the DC motor (30). The control unit (50) receives the output current to compare to a threshold current value, thus controlling the voltage compensation unit (60). Accordingly, the DC power voltage (Vo) is adjusted to adjust the speed of the DC motor (30).
Abstract:
A diindenothiophene derivative of the following formula (1) is disclosed: wherein each of G1, G2, G3 and G4 is independently an unsubstituted or substituted C6-C40-aromatic group or a C1-C40-aliphatic group; A is an electron-withdrawing group; and D is an electron-donating group. The inventive diindenothiophene derivatives can be used in a dye-sensitized solar cell.
Abstract:
The present invention relates to a method, apparatus and system for accessing remote files, wherein the method for accessing remote files comprising the following steps: obtaining download operation information for downloading a file in an operational system server; redirecting the download operation to a file server with safety space; saving a real copy of the downloaded file in the safety space and enumerating a corresponding virtual copy in the safety space. In the present invention, local file operations are redirected to the network file operations of network file storage system by redirecting the download operation on the file in the operational system server to the file server instead of being saved in the local user terminal to realize the “Not to local” effect for the key file. Even when it is power-off and then restarted, the data will not be saved in the local user terminal to achieve an effect close to “physical-like isolation”, which solves the safety problems of the offline key file much better.
Abstract:
Provided is a film having a thickness of less than 500 μm comprising a polymer and a plurality of surface-modified hexagonal boron nitride particles dispersed therewithin. The polymers can be polyimide or epoxy. A process for preparing the film by casting is provided.
Abstract:
A ventilator includes a base, a drive device disposed on the base, an impeller coupled to the drive device and driven by the drive device, and a cover assembled with the base to define a closed area between the cover and the base for receiving a first circuit board therein, wherein when an AC power source is input to the first circuit board to be converted, a DC power source is output to drive the drive device.
Abstract:
Provided, are multi-layer chip carriers comprising an asymmetric cross-linked polymeric dielectric film, and processes for making the chip carriers.
