Abstract: An intermediate representation construction method is provided. The method includes: obtaining a first intermediate representation (IR), where the first IR includes a computing statement, the computing statement includes a tensor and an operator, an operation represented by the operator is performed by a computing unit, the computing unit is configured to perform an operation on data that is migrated through a first storage location and a second storage location sequentially, and the tensor is data that is used when the operation represented by the operator is performed; and generating a second IR based on the computing statement, where the second IR includes first data migration information and data segmentation information.

Abstract: A stopping device for a conveying process of an object and a conveyor system are provided. The stopping device includes: a pedestal; a driving structure rotatably connected to the pedestal through a first spindle; a stopping arm rotatably connected to the pedestal through a second spindle; and a linkage rod connected between the driving structure and the stopping arm. The driving structure is configured to drive the linkage rod to move, so that the linkage rod drives the stopping arm to rotate about the second spindle between a first position and a second position.

Abstract: A grinding head includes: a guide rail; a first grinding assembly and a second grinding assembly which are located at two ends of the guide rail respectively and can move along the guide rail; and a number of filling assemblies, which are disposed between the first grinding assembly and the second grinding assembly, wherein dimensions and/or quantity of the filling assemblies are based on a width between the first grinding assembly and the second grinding assembly, wherein the filling assemblies can cooperate with the first grinding assembly and the second grinding assembly to form an entire grinding bottom face. The width of the bottom face of the grinding head can be adjusted so that the waste of grinding cloth due to grinding a thin display is panel surface by a grinding head with a wide bottom face can be avoided and the operating efficiency can be enhanced.

Abstract: The present disclosure relates to a positioner and positioning equipment, and relates to the field of display technology. The positioner includes a bottom face and a first side face which are perpendicular and adjacent to each other, the first side face being configured to abut against a work piece to be positioned so as to position the work piece to be positioned, the bottom face being provided with a magnetic member.

Abstract: A transportation main roadway and stope branch roadways are arranged by adopting a wangeviry coal mining method. A plurality of stope branch roadways are divided into multiple mining stages, based on which the stope branch roadways are skip-mined; and coal pillars are not reserved among the stope branch roadways. The transportation main roadway is a main transportation channel, and the stope branch roadways are coal mining roadways. All the stope branch roadways are sequentially stoped in a skip-mining manner according to the designed mining sequence and are sequentially and timely filled. The coal never stoped or the filled stope branch roadways is/are used as supports for controlling roofs at the two sides of the stope branch roadways, and the stope branch roadways are sequentially stoped according to a plurality of mining stages, and finally the coal pillar-free mining is realized.
