Abstract: Provided is a telescopic cylinder including a plurality of sleeves arranged in a nested configuration and having mutually parallel central axes. Each inner sleeve cooperates with an outer sleeve adjacent thereto to enable relative sliding such that each inner sleeve can extend and collapse relative to that outer sleeve. The telescopic cylinder further includes guide assemblies. Each guide assembly includes rollers and a rail that are configured as a set. The rollers are provided on left and right sidewalls and rear walls of the inner sleeves and the rails are correspondingly provided on left and right sidewalls and rear walls of the outer sleeves. The rollers and the rail in the same guide assembly are provided on an outer wall surface of the inner sleeve and an inner wall surface of the corresponding outer sleeve, respectively, thereby guiding movement of the inner sleeve relative to the outer sleeve.

Abstract: The present invention relates to a suspension system and an imaging system. The suspension system includes a rotating mechanism, a suspension column, and a carrying apparatus. The rotating mechanism includes a rotating member and a motor unit, and the motor unit is connected to the rotating member and drives the rotating member to rotate. The suspension column is provided with a first accommodating cavity, and the first accommodating cavity is used to accommodate at least a portion of the rotating mechanism. A first end of the carrying apparatus is connected to a bulb tube apparatus of an imaging device, and a second end thereof is connected to the rotating member.

Abstract: Disclosed is a low-expansion borosilicate transparent glaze, a preparation method thereof, and use thereof in preparation of a glaze product by secondary fusion-cast molding. The low-expansion borosilicate transparent glaze has raw material composition by mass percentage including: 72%-80% of SiO2, 4%-12% of B2O3, 4%-12% of Na2O, 0.1%-4% of CaO, 0.1%-6% of Al2O3, 0-0.05% of Fe2O3, 0-2% of MgO, 0-2% of K2O, 0-2% of ZnO, 0-2% of BaO, 0-2% of ZrO2, 0-0.5% of Li2O, and 0-0.5% of TiO2, wherein a sum of mass percentages of SiO2, B2O3 and Al2O3 is 85%-95%. The preparation method includes steps of: (1) after mixing dried raw materials, melting at 1400-1540° C. to obtain a high-temperature glass melt; (2) cooling the high-temperature glass melt to 1150-1230° C. to mold; and (3) annealing a molded glass at 530-600° C. to obtain the low-expansion borosilicate transparent glaze.

Abstract: The present application provides a suspension device and an X-ray imaging system. The suspension device is configured to bear a tube device of an X-ray imaging system. The suspension device includes a plurality of sleeves and a guide rail assembly. Cross-sections of the plurality of sleeves have substantially the same shape but different sizes. The plurality of sleeves are sequentially arranged. The guide rail assembly is provided between at least one sleeve and another sleeve adjacent thereto. The guide rail assembly includes a protruding member extending along a surface of the at least one sleeve and a sliding member provided on the another sleeve and engaging with the protruding member. The sliding member is capable of moving relative to the protruding member so as to drive the sleeves to move relative to each other.
