The invention relates to a process cartridge, a manufacturing method of the cartridge, and an image forming apparatus. The photoreceptor assembly (10) and the developing assembly (11) are connected in such a way that the side plates of the photoreceptor assembly (10) and the developing assembly (11) The parts (10a, 11a) are in surface contact, so that the pin insertion holes (40, 46) respectively formed on the side plate parts (10a, 11a) overlap, and the connecting pins are pressed into the above-mentioned pin insertion holes, and one side plate part The fitting protrusion (47) on (11a) is elastically fitted into the fitting hole (41) on the other side plate portion (10a). The photoreceptor assembly (10) and the developing assembly (11) are connected by an inexpensive structure without increasing the number of parts such as connecting plates, and the work can be performed simply without using jigs and the like.

The invention provides a screen for effectively utilizing space. A support leg (1B) comprises: a a support leg body (6) shaped substantially like a pillar, four leg sections (7) that support upright the support leg body (6) by abutting, at each one end, a placement surface, and a connection member (8) that is attached to the support leg body (6) and connects together the other end of each of the leg sections and the support leg body. The connection member (8) pivotally supports the other end of at least any of the leg sections (7) about a shaft substantially parallel to a vertical shaft. Through causing each leg sections (7) to rotate relative the connection member (8) using a shaft parallel with the vertical shaft as a center, the angle formed between each leg sections (7) using the support leg body (6) as the center is properly changed.

The invention discloses a double-channel variable damping hydraulic cylinder. The double-channel variable damping hydraulic cylinder comprises a cylinder body, a piston rod and a stopper body, whereinthe piston rod is movably connected with the cylinder body, the stopper body is arranged in the cylinder body, the stopper body comprises a fixed stopper, a first piston and a second piston which arerespectively arranged on both sides of the fixed stopper, matching holes which are in sliding connection with the piston rod are respectively formed in the first piston and the fixed stopper, the second piston is fixedly connected to the end of the piston rod, the first piston and the second piston respectively form a first cavity and a second cavity together with the fixed stopper, the first piston and the second piston are respectively connected with a first elastic piece and a second elastic piece which are arranged on both ends of the cylinder body, a first oil way and a second oil way are formed in the fixed stopper, and adjusting mechanisms which are used for adjusting the conduction caliber of the first oil way and the second oil way are respectively arranged on the first oil way and the second oil way. The double-channel variable damping hydraulic cylinder has the advantage of simple structure, and two-way damping adjustment of extension and retraction of the piston rod can berealized, thereby adjusting the speed of the knee joint swing phase and the stability of the support phase.

The invention relates to a tablet computer support. The tablet computer support comprises a base and a gripper device arranged on the base. The base comprises a base housing and an arch-shaped rail piece arranged in the base housing. Arch-shaped slideways are arranged on the arch-shaped rail piece; an upper slide block is arranged on each arch-shaped slideway; and a lower slide block is arranged under the arch-shaped slideway. A gripper fixing seat is arranged above the upper slide block, and a blocking piece is arranged on the gripper fixing seat. A containing cavity is arranged in the center of the blocking piece, and a rotating disc is arranged in the containing cavity. The gripper device comprises a fixed gripper, a cover plate and a movable gripper arranged between the fixed gripper and the cover plate. A lock catch device and an unlocking inserting piece are mounted in the fixed gripper. The tablet computer support is simple in structure, convenient to install and capable of being used for supporting tablet computers of different sizes and specifications, can adjust the tablet computers in multiple angles, and is provided with corresponding gears to enable the supporting state of the tablet computers to be more stable.

The invention discloses a novel variable-damping hydraulic cylinder. The novel variable-damping hydraulic cylinder comprises a cylinder body, a piston rod movably connected with the cylinder body anda piston body arranged in the cylinder body, the piston body comprises a fixing piston, a first piston and a second piston, the first piston and the second piston are arranged on the two sides of thefixing piston separately, the first piston and the fixing piston are each provided with a matching hole slidably connected with the piston rod, the second piston is fixedly connected with the end of the piston rod, a first cavity is formed by the first piston and the fixing piston, a second cavity is formed by the second piston and the fixing piston, the first piston and the second piston are connected with a first elastic part and a second elastic part which are arranged at the two ends of the cylinder body respectively, the first cavity communicates with the second cavity through an oil waychannel formed in the fixing piston, and an adjusting mechanism capable of adjusting the guiding port diameter is arranged in the oil way channel. According to the novel variable-damping hydraulic cylinder, the structure is simple, piston rod extension and contraction two-way damping adjusting can be achieved, and then the speed of knee joints in the swinging period and the stability of the knee joints in the supporting period can be adjusted.

The invention discloses a pre-stressed anchor rod type steel internal support structure of a continuous arched slope protection pile and a construction method of the pre-stressed anchor rod type steel internal support structure Slope protection piles which are arrayed in a foundation pit are arranged transversely and anchorage forces of all the pre-stressed anchor rods distributed at intervals are transferred to the slope protection piles through anchor heads; the section steel internal support structure is formed by connecting an upper layer of I-steel and a lower layer of I-steel which are mutually parallel, connecting plates which are connected to the external faces of air-adjacent sides of the two I-steels, and anchor plates as well as end sealing plates which are connected to adjacent wing edges at slope-adjacent sides of the two I-steels; a vertical view of each section of the steel internal support structure is in an arch which is connected by three parts as follows: a middle part, a left part and a right part; the whole section steel internal support structure and the slope protection piles form a continuous arch; the middle part of each section of section steel support is flat as well as straight and connected with the anchor plates; the outer edge of the middle part is flushed with the air-adjacent sides of the slope protection piles; the left and right parts of each section of section steel support are located at the two sloping sides of the arch; and two external end supporting lugs of each section of section steel support are fixedly connected with left and right slope protection piles. According to the pre-stressed anchor rod type steel internal support structure and the construction method thereof disclosed by the invention, problems that the support of the external foundation pit projects out of the pile body, a foundation trench space is occupied as well as recycling and reutilization is unavailable are solved.
