Publication number: 20190170143Abstract: Provided is a fluid machine configured such that liquid supplied to a working chamber from the outside of the fluid machine is dispersed extensively in the working chamber. This fluid machine is constituted of a screw rotor and a casing for accommodating the screw rotor and is provided with a liquid supply section for supplying liquid into a working chamber from the outside. The liquid supply section is configured so that liquid is dispersed in the longitudinal direction of the tooth groove of the screw rotor rather than in the width direction thereof.Type: ApplicationFiled: August 22, 2017Publication date: June 6, 2019Inventors: Kotaro CHIBA, Masahiko TAKANO, Toshikazu HARASHIMA, Kosuke SADAKATA, Kentaro YAMAMOTO, Takeshi TSUCHIYA, Masanao KOTANI, Ryoji KAWAI, Minako KANADA

Publication number: 20190136183Abstract: There is provided a method of inducing differentiation of bone marrow stromal cells to neural cells or skeletal muscle cells by introduction of a Notch gene. Specifically, the invention provides a method of inducing differentiation of bone marrow stromal cells to neural cells or skeletal muscle cells in vitro, which method comprises introducing a Notch gene and/or a Notch signaling related gene into the cells, wherein the finally obtained differentiated cells are the result of cell division of the bone marrow stromal cells into which the Notch gene and/or Notch signaling related gene have been introduced. The invention also provides a method of inducing further differentiation of the differentiation-induced neural cells to dopaminergic neurons or acetylcholinergic neurons. The invention yet further provides a treatment method for neurodegenerative and skeletal muscle degenerative diseases which employs neural precursor cells, neural cells or skeletal muscle cells produced by the method of the invention.Type: ApplicationFiled: January 7, 2019Publication date: May 9, 2019Applicant: SanBio, Inc.Inventors: Mari DEZAWA, Hajime SAWADA, Hiroshi KANNO, Masahiko TAKANO

Publication number: 20190128264Abstract: The objective of the present invention is to reduce loss factors that occur inside an oil-cooled screw compressor and to improve energy efficiency. In oil-cooled screw compressors, compression is carried out by reducing the volume of an operation chamber in which a gas to be compressed and an oil are mixed and contained, and when a predetermined rise in pressure is complete, a discharge port opens and the gas to be compressed and the oil are discharged. In the operation chamber, the reduction in volume continues and reaches zero, such that the operation chamber disappears, and the opening area of the discharge port also gradually decreases. Immediately before the operation chamber disappears, the ratio of the oil within the operation chamber is high and the opening area of the discharge port is small. Therefore, the discharge resistance increases and the internal pressure dramatically rises, and this has led to increases in the torque rotating the rotor.Type: ApplicationFiled: March 30, 2017Publication date: May 2, 2019Inventors: Hirotaka KAMEYA, Hideharu TANAKA, Masahiko TAKANO, Takeshi TSUCHIYA
