Abstract: The present disclosure provides an electromagnetic levitation train-track system. Tracks are arranged on two sides of a roadbed or track beams, and a magnetic levitation train runs on the tracks. The system includes a traction guide electromagnet horizontally arranged on supporting arms on two sides of the magnetic levitation train, a linear motor stator horizontally arranged at a relative position on the track, the linear motor stator and the traction guide electromagnet horizontally arranged in the magnetic pole directions, a core linear motor formed by the linear motor stator and the traction guide electromagnet at a certain magnetic gap, and an E-shaped cross section levitation electromagnet and a gap sensor arranged at the bottom of the magnetic levitation train and levitated below an armature plate horizontally arranged at the bottom of the track.

Abstract: In one aspect of the present invention, a sandwich-type surgical structure for joining tissue includes a movable handle portion; a body portion extending distally from the handle portion; a nail assembly operatively connected to a distal end of the body portion and a first membrane-like structure; the nail assembly includes a first member; a second member; a first group of nails; a second groups of nails, and the length of the nail of the first group is in the range of 5-95% length of the second group of nail, so that the force applying to the tissue will vary depending on the length of the nails, and the first membrane-like structure immediately contacts with the tissue contacting surface of the first member of the nail assembly.

Abstract: A sleeve type fixing method for anastomosis for tubular organs, using an anastomosis device which has an inner and an outer ring. The outer ring is made of elastic material, and the inside of the lower portion of the outer ring has an inwardly protruding ring. The protruding ring is clamped to the connecting portion of the inner ring. In operation, one intestine is sleeved and fixed on the flange of the anastomosis portion of the inner ring, and the outer ring is overturned to let the lower edge overturn. Then another intestine is sleeved and fixed on the outer ring, and both the outer ring and the intestine are overturned so that the intestine is connected in the inner edge of the outer ring. Finally the inner ring is inserted and the two intestines overlapped on the anastomosis portion of the inner and outer ring.

Abstract: The invention relates to a linear permanent magnet driving system and a permanent magnet driving maglev train rail system, the linear permanent magnet driving system comprises spiral rotors and stators, wherein at least one of the spiral rotor and the stator adopts the structure having a permanent magnet while the other one adopts the structure having the permanent magnet or a magnetizer; when the spiral rotors are driven by an engine to rotate, linear motion of the spiral rotors is achieved by means of the magnetic force between both, and speed of the linear motion of the spiral rotors can reach supersonic speed at most. By applying the linear permanent magnet driving system to the permanent magnet driving maglev train rail system, the entire rail can avoid the use of both permanent magnet and driving coil, and the construction cost of maglev train rail is equivalent to that of the current high-speed wheel/rail.
