Abstract: A power supply system for a medical X-ray imaging device is described, which includes power connector configured to be connected to a power grid. The power supply system can efficiently reduce the time for reconnecting the medical X-ray imaging device to a power supply to recover to a normal working state. In addition, the medical X-ray imaging device is also provided.

Abstract: A waste discharge pipe having: a pipe main body, provided with a waste inlet, a waste discharge port, and an overflow port, wherein the waste discharge port and the waste inlet face different directions; the waste inlet is configured to be communicated with a waste outlet of a toilet seat body; the pipe main body is configured to be capable of rotating, between an initial position and a waste discharge position, relative to the toilet seat body around the central axis of the waste inlet; and when the pipe main body is located at the initial position, the opening of the waste discharge port face upwards, and the overflow port is located at the lower side of the waste discharge port and located at the upper side of the waste inlet.

Abstract: A wall-mounted toilet system, comprising: a wall-mounted bracket (1) and an in-wall drain pipe (2); a toilet body (3), which is fixed to the wall-mounted bracket (1) and has a bowl (31) and a mounting cavity (32); and a drain device (4), which is connected to the toilet body (3), communicates with the in-wall drain pipe (2), and comprises a rotary drain pipe (41) arranged in the mounting cavity (32), wherein one end of the rotary drain pipe (41) communicates with the bowl (31), and is configured to rotate relative to the toilet body (3) between an initial position and a drain position, such that when the rotary drain pipe rotates to the initial position, a water seal is formed in the bowl (31); and when the rotary drain pipe rotates to the drain position, dirt in the bowl (31) is discharged into the in-wall drain pipe (2).

Abstract: A wall-mounted toilet bracket includes a bracket body provided with a wall body connection portion and a toilet connection portion, the wall body connection portion being configured to be connected to a wall body so as to arrange the bracket body outside the wall body and to fix the bracket body to the wall body, the toilet connection portion being configured to be connected to a toilet body so as to fix the toilet body to the bracket body, and the bracket body being configured in such a way that the projection of the bracket body on the wall body is located within the range of the projection of the toilet body on the wall body.

Abstract: A captive screw includes a sleeve and a screwing member. The sleeve includes a body portion and a positioning protrusion. The positioning protrusion protrudes from the body portion, and forms a channel. The screwing member includes a head portion, a neck portion and a threaded portion. The neck portion connects the head portion and the threaded portion. The neck portion passes through the channel. The head portion and the threaded portion are located on the positioning protrusion. The threaded portion includes a wider section and a narrower section. The wider section is connected to the neck portion. The narrower section is connected to the wider section. The diameter of the channel is less than a major diameter of the wider section. The diameter of the channel is greater than or equal to a major diameter of the narrower section and a minor diameter of the wider section.

Abstract: The present invention relates to a composite powder, preparation and use thereof. The composite powder according to the present invention is prepared by intimately mixing an irradiated or non-irradiated rubber latex with a slurry of inorganic particles in a ratio corresponding to that of rubber particles to inorganic particles in the composite powder according to the present invention, and then drying the resultant mixture. The composite powder according to the present invention comprises agglomerates composed of powdery rubber particles and inorganic particles, with inorganic particles being uniformly distributed either inside the agglomerats or both inside the agglomerates and on the surfaces thereof. The composite powder according to the present invention can be easily dispersed in plastic matrixes and thus can be compounded with plastics to produce toughened plastics and thermoplastic elastomers.
