Abstract: A device and method for sputtering and depositing metal on the surface of magnetic powder materials utilizes a vacuum chamber, a vacuum pump set, a magnetron sputtering target, a cathode ion source, a water-cooled anode, and a sample holding component arranged in the vacuum chamber. The sample holding component is a sample roller, an axis of the sample roller is arranged in a horizontal direction, the sample roller can rotate around the axis thereof. Two ends of the sample roller are open, and the sample roller further comprises a power device capable of driving the sample roller to rotate. The cathode ion source and the magnetron sputtering target extend inwards into the sample roller from the opening in the same end of the sample roller. The water-cooled anode extends inwards into the sample roller from the opening in the other end of the sample roller.

Abstract: A system including user device of a preset administrative user, a server, and a smart device. The user device sends a binding request for the smart device to the server, the binding request being used for instructing the server to bind the smart device. The server records an administrative permission for the administrative user to the smart device in the process of binding. When a near-field communication signal from any user is received, the smart device identifies the identity of the user; and when the user is determined as the administrative user, the smart device establishes a near-field communication connection with an electronic device of the user to allow the user to configure the smart device. With the technical solution of the present disclosure, a device may be configured based on software, and accordingly, security dangers of a physical key are eliminated while configuration operations are simplified.

Abstract: An information display method is disclosed to solve a problem of tediousness and inefficiency of a process of displaying an information set corresponding to an information portal in existing technologies. The method includes: acquiring a selection instruction for an information portal; acquiring an information set corresponding to the information portal; and displaying the information set. The present disclosure further discloses an information display apparatus and a smart television.

Abstract: The present disclosure discloses an example method and device for page returning. A page scrolling processing is conducted in response to a pull-down operation of a user. When it is detected that a pull-down distance of a page content of a current page is longer than a threshold, a page returning operation is implemented. The present techniques not only cause the process of page returning interactive, playable, and terminable but also add a new universal scroll-down sliding operation to increase the usability of the returning operation.

Abstract: A high-efficiency triple-junction thin-film photovoltaic device in which the haze ratio is high and the short-circuit current values obtained from each of the photovoltaic layers are equalized. A thin-film photovoltaic device comprises a transparent electrode layer and three silicon-based photovoltaic layers stacked in sequence on a substrate. The transparent electrode layer has at least one opening formed by an etching treatment that exposes the surface of the substrate, and the haze ratio of the transparent electrode layer relative to light of a broad wavelength region is at least 60%.
