The invention discloses a split training device, and relates to a physical training instrument. A backrest (11) is arranged on the upper rear portion of a seat plate (14). The inner end of a rotary plate (1) on one side is hinged to the front portion of one side of the seat plate, and a knee pressing plate is arranged in the middle of the rotary plate. The inner end of a rotary plate (18) on the other side is hinged to the front portion of the other side of the seat plate, and a knee pressing plate is arranged in the middle of the rotary plate. The middle or outer end of the rotary plate on one side and the middle or outer end of the rotary plate on the other side are connected with one ends of two stay cords respectively. The middle portions of the two stay cords are located on sheaves (10) at the two ends of the backrest respectively. The outer ends of the rotary plate on one side and the rotary plate on the other side are controlled to be separated through the other ends of the two stay cords. Legs are separated through the rotary plates connected with the seat plate, bending of knees is prevented through the two knee pressing plates, and the requirement of independent practice of splitting is met.

The invention belongs to the field of a windproof observation deck for municipal engineering, and particularly to the observation deck for municipal engineering. The observation deck comprises windproof observation deck unit which are successively arranged. The windproof observation deck unit comprises a seat mechanism, a windproof moving mechanism and a windproof action mechanism. The seat mechanism is mounted above the windproof action mechanism. The windproof moving mechanism is mounted on the windproof action mechanism. The seat mechanism realizes resting of sightseeing visitors and landscape observing. Furthermore the seat mechanism can trigger motion of the windproof action mechanism, thereby driving action of the windproof moving mechanism so that a wind shield mounted on the windproof moving mechanism prevents harm of blown wind to visitors, thereby performing a windproof function.

The invention relates to a knee osteoarthritis rehabilitation bed, which comprises a bed board, a backrest, a lifting massage device and a correcting device. The right end of the bed board is connected with the angle-adjustable backrest in the hinged mode. A square hole is formed in the middle of the bed board, and supporting columns are arranged at the bottom of the bed board. The lifting massagedevice is located in the square hole formed in the middle of the bed board. The lifting and massaging device is installed on the lower end face of the bed board. The correcting device is connected with the top of the left end of the bed board. The correcting device comprises a correcting frame, a correcting sliding column, a correcting connecting column, a correcting spring, a correcting rotary frame, two correcting clamping jaws, a clamping jaw adjustment push rod and a clamping jaw positioning board. The knee joint rehabilitation device can solve the problems in the prior art that, the position of the knee cannot be automatically adjusted during rehabilitation treatment of an existing knee arthritis patient in the prior art, the knee of the patient needs to be massaged manually, the magnet therapy of the knee cannot be carried out when the knee of the patient is massaged, and the shank of the patient cannot be bent when the knee of the patient is lifted.

Pipe clip has a transverse axis (26) around which a tensioned clip band (7) is bent at a distance (DELTAR) from the middle point of ball zones (4, 5, 6). The inner radius of the bent of the tensioned clip band around the transverse axis is smaller than the outer radius of the ball zones so that the sum of the distance (DELTAR) and the inner radius of the bend is larger than the outer radius of the ball zones. An Independent claim is also included for a connecting arrangement of two pipes and the pipe clip. Preferred Features: The inner peripheral edges (30, 31) of the clip band are rounded.

The present invention provides a photographic device, having a reliable shielding component with a simple structure. The photographic device comprises the shielding component for selectively shielding an opening of a housing of an objective lens, wherein the shielding component includes a shielding piece with flexibility configured to slide on a lower side edge of the housing of the objective lens in a direction vertical to an optical axis of the objective lens; a movable component configured to make the shielding piece to move between a shielding position of shielding the opening of the housing and an opening position of baring the opening; and a guiding component configured to limit a moving path of the shielding piece, wherein the guiding component includes a horizontal guiding part configured to limit a lower moving path of the housing of the objective lens in a horizontal direction, a vertical guiding part configured to limit a moving path in a vertical direction, and a bending guiding part configured to guide the shielding piece from the vertical guiding part to the horizontal guiding part.

The invention discloses a manufacturing method for a wafer-level uniaxial strain Ge on a SiN buried insulating layer based on a silicon nitride stress thin film and scale effect. The manufacturing method is implemented by the steps of cleaning a GeOI wafer, and performing He ion implantation; depositing a SiN thin film with the pressure stress of greater than minus 1.1GPa or an SiN thin film with the tensile stress of greater than 1.1GPa on the Ge layer on the top layer of the GeOI wafer after ion implantation, and etching the SiN thin film to form a strip-shaped array; performing annealing processing on the GeOI wafer with the SiN thin film array; and etching and removing the SiN thin film array from the surface of the GeOI wafer to obtain the wafer-level uniaxial strain GeOI material. According to the manufacturing method, due to the uniaxial stretching or uniaxial compression plastic deformation of the SiN buried insulating layer under the effect of the strip-shaped SiN thin film, strain is introduced to the Ge layer on the top layer, so that the wafer-level uniaxial strain Ge can be used for manufacturing the GeOI wafers required by the ultra-high-speed, low-power-consumption and radiation-resisting semiconductor devices and chips.
