摘要:
A coil for a magnetic resonance imaging device consists of multiple coil elements arranged about an imaging space. Each coil element comprise radiating structures oriented at an angle to a tangent of the imaging space. Angling the radiating structures reduces mutual coupling between coil elements and enhances the penetration of the radio frequency field to the imaging space.

Processing instruction grouping information is provided that includes: reading addresses of machine instructions grouped by a processor at runtime from a buffer to form an address file; analyzing the address file to obtain grouping information of the machine instructions; converting the machine instructions in the address file into readable instructions; and obtaining grouping information of the readable instructions based on the grouping information of the machine instructions and the readable instructions resulted from conversion. Status of grouping and processing performed on instructions by a processor at runtime can be acquired dynamically, such that processing capability of the processor can be better utilized.

The disclosure provides a forming machine without pattern casting, including: a multi-axis motion system; a cutting system, connected with the multi-axis motion system; a driving system, driving the multi-axis motion system to move; and a machining base, wherein the machining base includes a fixing seat and a turnover mechanism, wherein the turnover mechanism is revolvably connected with the fixing seat. Since the forming machine without pattern casting of the disclosure adopts a tilting type and needs no working platform, most of the waste sand grains generated from cutting fall freely into the shakeout groove arranged below the fixing seat, and will not fly into the multi-axis motion system, and will not cause stop failure; thus the precision and service life of the forming machine without pattern casting are improved.

The disclosure provides a containerless casting forming machine, including: a multi-axis motion system which at least includes an X-axis motion system, a Y-axis motion system and a Z-axis motion system, and a workbench which is below the multi-axis motion system; and further includes: a moving platform system below the workbench, including a moving bracket which can reciprocate along the direction parallel to the X axis, a lifting device provided on the moving bracket, which is used for lifting and supporting the workbench to enable the linkage between the workbench and the moving bracket. The containerless casting forming machine of the disclosure can move the workbench without a lifting tool, and machine a casting mold with a large size and a complex cavity, and causes little pollution to the environment.

A locating beam and a robot linear motion unit having the same, wherein the locating beam comprises a first support beam and a second support beam which are parallel to each other, a crossbeam connected between the first support beam and the second support beam and is vertical to the beams, and a joints between the crossbeam and the beams is provided with a right-angle connecting piece. The robot linear motion unit includes a motion track and a transmission mechanism arranged along the extension direction of the motion track, and the motion track is arranged on a surface of the locating beam. Arranging the crossbeam and right-angle connecting pieces between the first support beam and the second support beam in the locating beam, improves the mechanical structure strength, reduces deflection deformation and twist deformation of the locating beam, and improves the impact resistance of the robot linear motion unit.
