    摘要： The present invention is directed to a hopper structure for feeding a powdery material adapted to enable gas, etc., generated in a plasticizing cylinder to escape irrespective of the state of feed of the powdery material within a hopper. To this end, the hopper structure of the present invention is arranged such that the plasticizing cylinder is formed with a material feed port for providing a communication between the interior and the exterior of the plasticizing cylinder, and that a hopper is provided for feeding a powdery material via the material feed port to the outer periphery of a screw within the plasticizing cylinder, and that a material feeding tube is mounted to the bottom of the hopper for allowing a communication between the bottom of the hopper and the vicinity of the outer periphery of the screw, with a gap for the removal of air being formed between the outer peripheral surface of the material feeding tube and the inner peripheral surface of the material feed port, the gap extending from the vicinity of the outer periphery of the screw to the exterior. The present invention is applied for the feed of a powdery molding material into the plasticizing cylinder of an in-line screw injection molding machine or of an in-line screw extrusion molding machine.

    摘要： Disclosed is a method for constructing a nucleus-implanted egg, a parthenogenetic embryo and for producing a parthenogenetic mammal each having 2 haploid genome sets originating in mammalian ova, and provides methods of constructing a nucleus-implanted egg having a haploid genome set derived from primitive ovarian follicle egg (ng ovum) and a haploid genome set from MII phase (second meiosis metaphase) egg (fg ovum), a parthenogenetic embryo and a parthenogenetic mammal, including steps (1) introducing ng ovum into a nucleus-deleted deleted germinal vesicle stage (GV) egg, developing the obtained egg to MII phase by in vitro maturing and culturing to prepare a first nucleus-implanted egg, and (2) extracting MII phase chromosome from the first nucleus-implanted egg and introducing it into other fg ovum to prepare a second nucleus-implanted egg, wherein a ng or fg ovum from which an imprinted gene undergoing epigenetic modification during sperm generation is used.
