    • A callus and suspension culture cells containing taxol as an effective component, and a process for producing taxol therefrom, are provided. The callus and suspension culture cells containing taxol in a high content can be induced and proliferated by culturing a tissue of a plant belonging to the genus Taxus, particularly its female gametophyte. The process for cell culture is advantageously carried out in the presence of a particular combination of plant growth regulators known per se in a growth medium. A callus or suspension culture cells containing at least taxol as an effective component can be stably provided, making it possible to effectively produce taxol.

    • An abrasive grains classifying apparatus is used to classify abrasive grains based on their sizes that can be determined by distances between mutually opposed surfaces of the respective abrasive grains. The abrasive grains classifying apparatus is provided with: a first gap portion 35 which includes two rollers 24 and 32 disposed at a predetermined distance L2 from each other and also which classifies the abrasive grains 60 into first abrasive grains 60b and 60c capable of passing through between the rollers 24 and 32 and second abrasive grains 60a incapable of passing through between the two rollers 24 and 32; and a second gap portion 54 which includes two rollers 54 and 69 disposed at a distance L3 smaller than the distance L2 in the first gap portion 35 from each other.
    • 磨粒分级装置用于根据其各自的磨粒相互相对的表面之间的距离可确定的尺寸对磨粒进行分类。 磨粒分级装置设置有:第一间隙部分35,其包括彼此以预定距离L2设置的两个辊24和32,并且还将磨粒60分类成能够穿过第二磨粒60b和60c之间的第一磨粒60b和60c 辊24和32以及不能穿过两个辊24和32之间的第二磨料颗粒60a; 以及第二间隙部分54,其包括设置在比第一间隙部分35中的距离L2小的距离L3处的彼此相对的两个辊54和69。
