Abstract: The present application provides a glass fiber nozzle structure, bushing and production device. The glass fiber nozzle structure includes a nozzle body and a hole provided on the nozzle body. The hole includes an upper hole portion and a lower hole portion communicated with the upper hole portion and located below the upper hole portion. The lower hole portion has an elongated cross-section. A projection of the lower hole portion is located within a projection of the upper hole portion in a projection on a plane perpendicular to an axis line of the lower hole portion. A length and a width of the lower hole portion have a ratio of 5:1 to 12:1. The glass fiber nozzle of the present application has a simple structure and a long service cycle, and an aspect ratio of flat glass fibers produced by the nozzle structure is maintained between 2.7 and 4.2, thereby effectively improving performance of the flat glass fibers.

Abstract: A manufacturing method for mass production for a tissue or cell microarray, which is characterized in comprising: using a molding device to mold tissue particles, cultivated cells or collected exfoliated cells (such as exfoliated cells from pleural effusion and ascites), forming the tissue particles from blended fresh tissue, tissue fixed by formalin or another solvent (such as alcohol and so on) or a tissue block embedded in paraffin (blended by a tissue blender), implanting the molded tissue or cells cores in a receptor wax or adhering the molded tissue or cells cores onto a metal plate, and then slicing to obtain a tissue or cell microarray.
