The shutdown of a compressor (10) installed in a refrigerant circuit (2) in air conditioning or refrigeration system is controlled so as to prevent unpowered reverse rotation of the compressor. Prior to terminating electric power to the compressor drive motor (24), the pressure within the system is relieved and substantially equalized across the compressor, thereby eliminating the possibility of unpowered reverse rotation of the compressor at shutdown. Pressure relief and equalization may be achieved by reducing the operating speed of the compressor to a low forward speed for a period of time prior to deenergizing the compressor drive motor. Pressure equalization may also be achieved by driving the compressor in reverse rotation prior to deenergizing the drive motor.

There is provided a medicine feeder capable of reducing or resolving factors of stagnant medicine pieces even when there are few remaining stagnant medicine pieces. A medicine feeder 10 includes an outer rotary body 20, an inner inclined rotary body 30, a lateral width regulation mechanism 70 operable to align solid medicine pieces that have been carried onto an annular upper end surface 23 of the outer rotary body 20 from the top of the inner inclined rotary body 30, and fallen medicine detecting means 56 for detecting a fallen medicine piece discharged after being aligned. A control portion 80 determines that no medicine pieces are contained any more when a non-detection time interval reaches a final prescribed time interval while performing rotation controls. Before stopping discharge operation, vibrating rotation control for rotating the inner inclined rotary body 30 while vibrating the inner inclined rotary body 30 is performed in order to resolve stagnation of remaining medicine pieces. Further before that, the lateral width of a medicine transfer path on the annular upper end surface 23 is increased stepwise by controlling the lateral width regulation mechanism 70 in order to resolve congestion of medicine pieces.

A left atrial appendage (LAA) closure (1) and a system (6) for delivering the LAA closure are disclosed. The LAA closure (1) includes supporting struts (11), wherein the supporting struts (11) are distributed peripherally around a first hub (10) and extend outward, the supporting strut (11) bifurcates at a first position (110) into a left branch (111) and a right branch (112). The left branch (111) of each supporting strut (11) and the right branch (112) of an adjacent supporting strut join each other at a second position (113) and extend distally to form a distal end. The LAA closure further includes a supporting rod (12) between adjacent supporting struts (11) which ensures stability, absence of irregular deformation and lateral slippage, of the LAA closure (1). With the supporting rods (12) between the adjacent supporting struts (11), the LAA closure (1) forms a dense mesh which imparts high overall strength of the LAA closure (1).

The present invention claims an application of a CNSI-Fe compound preparation in preparing a tumor hyperthermia drug used in conjunction with near-infrared light. When the compound preparation is used for low-temperature hyperthermia, the administration dosage can be decreased so as to reduce the occurrence of adverse reactions; the hyperthermia using the compound preparation has a low temperature, so that the surrounding normal tissues are not liable to be damaged, and the adverse reactions during the hyperthermia using carbon nanoparticles can also be reduced. Moreover, it is further proved that the CNSI-Fe compound preparation and the near-infrared irradiation are synergic. Based on the means and technical effects of low-temperature hyperthermia, the present invention has extensive clinical significance.
