Abstract: A titanium dioxide micro-nanocontainers, corrosion-resistant waterborne epoxy coatings and preparation method thereof, including preparation steps as follows: TiO2 micro-nano spheres are synthesized by applying hydrothermal method; a polyaniline layer doped with molybdate ions is deposited on the surface of TiO2 micro-nano spheres by adopting the method of in-situ chemical polymerization, TiO2/PANI-MoO42? micro-nano-spheres are obtained, then, polydopamine is encapsulated on the surface of TiO2/PANI-MoO42? micro-nano spheres to obtain titanium dioxide micro-nanocontainers; next, antirust filler, defoamer, dispersant and thickener are added into waterborne epoxy emulsion, then titanium dioxide micro-nanocontainers are added in the waterborne epoxy emulsion for dispersing and grinding, filtering and encapsulating to obtain component A; the waterborne epoxy curing agent and deionized water are mixed in proportion to obtain component B; component A is stirred, then it is mixed with the component B in proportion,

Abstract: Electronic displays and electronic devices including such electronic displays and antennas are provided for improved transmission of signals through circuitry of the electronic display. The electronic display may include multiple power supply tiles that are separated with non-conductive gaps to reduce circulation of eddy currents induced by the transmission signals. Moreover, voltage supply routing paths within the power supply tiles may be grouped to provide non-conductive gaps within the power supply tiles. Accordingly, the antenna may provide the transmission signals through the electronic display with improved efficiency based on reducing surface currents (e.g., eddy currents) on the electronic display.

Abstract: A rotor structure for reducing a working temperature in a shaft is disclosed. The rotor structure comprises a hollow shaft body and an inner shaft sleeve, the inner shaft sleeve is assembled in the hollow shaft body, and a first thermal insulating cavity is formed between the inner shaft sleeve and the hollow shaft body. The rotor structure according to the present disclosure can be applied to the motor, and can effectively reduce the working temperature of the inner surface of the hollow shaft of the motor and ensure the reliable operation of the motor.

Abstract: An electromagnetic dog clutch is disclosed to solve the technical problem in conventional electromagnetic dog clutches that the friction is easy to occur between a bearing seat and an end cap of a movable gear sleeve. The electromagnetic dog clutch comprises a movable gear sleeve (5) and a fixed gear sleeve (12) that mesh with each other for transmission. A first end cap (6) is provided on an outer side of the movable gear sleeve (5), a bearing (1) is provided on an outer circumference of the movable gear sleeve (5), the bearing (1) is embedded in a bearing seat (7), a rear end of the bearing seat (7) is provided with a positioning surface, and a front end of the first end cap (6) is a vertical plane that matches the positioning surface of the bearing seat (7).

Abstract: The present disclosure relates to the field of shaft sealing, and particularly relates to a sealing structure of an electric-machine-shaft extension end.

Abstract: The present disclosure relates to the technical field of welding, and particularly relates to a welding method for sealing a cooling-water channel of an electric-machine housing. The method includes the steps of: 1) seal the opened ends of the cooling-water channel using the sealing parts to form an S-shaped sealed cooling water channel inside the electric-machine housing; and 2) weld each of the sealing parts and the electric-machine-housing together by using the friction-stir-welding, in one single and complete single-welding-seam mode. The present disclosure utilizes the stirring head having a larger diameter to sufficiently stir-weld each of the sealing parts and the electric-machine housing all at once, i.e., welding in the single-welding-seam mode, so that the welding can be completed at one time, which, as compared with the conventional mode of double-welding-seam mode, has a higher operation efficiency, a better stability, and reduces welding duration by ½ to ?.

Abstract: The invention provides a safety lock for zipper bags, comprising a first pull block with a locking bar and a second pull block with a locking frame. Said locking bar is inserted into the locking frame to link the first pull block with said second pull block; said second pull block is further equipped with a release unit for detaching the locking bar from the locking frame. A slot is formed between said release unit and top surface of the second pull block. In the invention, the locking bar and the locking frame can connect and lock the two pull blocks which can be unlocked by pressing the pressing portions with certain force. Children are unable to open the zipper bag easily. Therefore, the invention can prevent children from mistakenly opening the zipper bag effectively and avoids loss of important documents and accidental ingestion of medicines.
