Abstract: A radiation beam field shaping device is made from a 3D printed frame that contains and gives shape to a granular material with bulk density of at least 3 g/cm3 and composed of metal grains having a size between 1 ?m and 4 mm. The frame has a hole in the bottom with surrounding walls that defines the desired beam shape. In one implementation, the metal grains are composed of solid tungsten alloy ball bearings and/or tungsten alloy powder.

Abstract: A fine knitwear of circular knitting machines with air permeable holes is a single face fabric knitted via a circular knitting machine with knitting fineness ?24 needles/inch. Each air permeable hole includes: at least one yarn located above the air permeable hole and formed via interactive movements of a Dial sinker and a plurality of latch needles perpendicular to the Dial sinker, and a first support loop and a second support loop that are formed via interactive movements of the Dial sinker and the latch needles and symmetrical against the yarn on the left side and the right side to support and tie the transferred yarn. The fine knitwear can meet market and consumers' requirements of providing more comfortable cooling, and the width of the air permeable holes can be changed flexibly in response to different requirements in the industry.
