The invention discloses a card conveying device and a card conveying method for printing codes on intelligent cards. The card conveying device comprises intermittent card conveying mechanisms, card transfer mechanisms and card moving mechanisms, wherein the card transfer mechanisms are used for conveying cards on which the codes are to be printed to code printing modules from the intermittent card conveying mechanisms and returning the cards with the codes printed on to the intermittent card conveying mechanisms, and the card moving mechanisms are used for sending the cards on which the codes are to be printed in the card transfer mechanisms into the code printing modules, returning the cards with the codes printed on to the card transfer mechanisms at the same time and then pushing the cards sent into the code printing modules for code printing in a movable mode. The card transfer mechanisms comprise driving devices, master control rotating shafts and a plurality of sets of transfer clamping bases. Each code printing module corresponds to a set of transfer clamping base, and each set of transfer clamping base comprises a card inlet transfer clamping base and a card outlet transfer clamping base which are fixedly connected onto the corresponding master control rotating shaft. The card conveying device has the advantages of being high in efficiency, simple in structure, favorable for follow-up hot-printing process and the like.

To provide a variable stator vane mechanism, for an axial flow compressor, which is excellent in durability, has a simple structure, and is realized at low cost. The variable stator vane mechanism for adjusting a mounting angle of a stator vane of an axial flow compressor includes: an arm coupled to the stator vane; a rotation ring coupled to one end portion of the arm and located at an outer surface of a casing of the axial flow compressor; a driving machine configured to rotate the rotation ring to cause the stator vane to pivot via the arm; and a friction pad mounted on the casing. The rotation ring is in frictional contact with the friction pad.

Letting a particle diameter be Dx (μm) when a cumulative particle volume cumulated from the small particle diameter side reaches x (%) of the total particle volume in a particle size distribution obtained regarding cerium oxide included in a polishing liquid using a laser diffraction / scattering method, D5 is 1 μm or less, and a difference between D95 and D5 is 3 μm or more.

The present invention provides an in vitro simulator which can simulate digestion and absorption processes of feed nutrient in the chicken alimentary tract, including maw and peptic digest chamber, small intestine digesting chamber and constant temperature system etc. The feed nutrient is completed by the maw and peptic digest chamber under the digesting course of the maw and peptic; chyme is converted to the small intestine digesting chamber continuously digested after the period of maw and peptic digestion, completing the digestion of the nutrient in the small intestine and the absorption of the digested nutrient, finally achieving the simulation of the digestion and absorption processes of the feed nutrient in the chicken alimentary tract in vitro; the constant temperature system provides heat preservation and vibrating mixture functions for the digestion course of the chyme in the maw, peptic digest chamber, small intestine digesting chamber, simulating the environment temperature of the chicken alimentary tract, gastrointestinal peristalsis and chyme mixture. The chicken in vitro simulating digestion device of the invention has a lower cost, simple operation, quick performance and better palingenesis.

Front feet are provided at a lower part of a cutting-machine main body via a foot holder. Furthermore, a slider positioned on a front side relative to the front feet is provided at the lower part. When a workpiece to be cut is to be cut by a blade, the cutting-machine main body is tilted so as to let the blade go down. When the cutting-machine main body is tilted, a state where the front feet are in contact with the workpiece is switched to a state where the slider is in contact with the workpiece. Then, by moving the cutting-machine main body forward while sliding the slider on the workpiece, the workpiece is cut by the blade. In the cutting operation, the front feet can get away from the workpiece. Therefore, damage of the front feet can be prevented, and the running cost can be suppressed.
