Patent number: 9587999Abstract: A device for measuring the state of contact of a measuring roller of a conveyor belt includes a pressure sensor provided on a rotating surface of the measuring roller, which rotates in contact with an inner peripheral surface of a conveyor belt stretched between pulleys. The pressure sensor detects resistance force acting when the conveyor belt rides over the measuring roller. A rotational position sensor detects the circumferential position, on the rotating surface, of the pressure sensor. The data detected are sequentially wirelessly transmitted to the outside of the measuring roller by a transmission unit installed on the measuring roller, and the transmitted detection data are received by a receiver.Type: GrantFiled: May 7, 2014Date of Patent: March 7, 2017Assignee: The Yokohama Rubber Co., LTD.Inventors: Atsushi Miyajima, Osamu Ozawa

Publication number: 20100151503Abstract: Disclosed are a method for detecting liver cancer capable of detecting liver cancer with high specificity and a diagnostic therefor, as well as a novel therapeutic drug for cancer having an excellent anticancer effect. The method for detecting liver cancer cells in a sample utilizes as an index the expression of dlk gene. The expression of dlk gene may be measured by immunoassay using an anti-dlk antibody or by measuring mRNA of dlk gene. The therapeutic drug for cancer comprises as an effective ingredient an antibody which undergoes antigen-antibody reaction with Dlk expressing on surfaces of cancer cells and which exerts anticancer action against the cancer cells.Type: ApplicationFiled: June 8, 2009Publication date: June 17, 2010Inventors: KOJI NAKAMURA, HIROKO ANZAI, HIROYUKI YANAI, ATSUSHI MIYAJIMA

Publication number: 20090131634Abstract: Mouse PCLP1 was identified by expression cloning with the use of a monoclonal antibody against a surface antigen of a cell line derived from mouse AGM. By fractionating PCLP1-positive/CD45-negative cells and culturing them in vitro, it was clarified that these cells differentiate into endothelial-like cells, angioblast-like cells, and hematopoietic cells. By transferring the PCLP1-positive/CD45-negative cells into a mouse defective in the hematopoietic function, the hematopoietic system was reconstructed over a long period of time. These facts indicate that the PCLP1-positive/CD45-negative cells contain mammalian hemangioblasts capable of expressing the activity as long-term repopulating hematopoietic stem cells (LTR-HSC). The present invention provides a method for preparing a cell fraction containing hemangioblasts, the cell fraction prepared by the method, and use of this cell fraction.Type: ApplicationFiled: October 17, 2008Publication date: May 21, 2009Inventors: Atsushi MIYAJIMA, Takahiko HARA
