Patent number: 11635006Abstract: A blow-by gas recirculation device that, while having a structure in which a passage for blow-by gas is in a head cover and an oil separator, an increase in size of an engine is suppressed and the risk of the freezing is mostly avoided by shortening the length of an external pipe for the blow-by gas. Therefore, the blow-by gas recirculation device guides blow-by gas from a crankcase to an intake passage through an in-cover gas passage formed inside a head cover. An oil separator that traps and removes oil from the blow-by gas is attached to the inside of the head cover. A pressure regulating valve is provided on the outlet side of the in-cover gas passage in the head cover. A separator outlet, which is an outlet for the blow-by gas in the oil separator, is overlapped on a blow-by gas inlet portion of the pressure regulating valve.Type: GrantFiled: April 14, 2020Date of Patent: April 25, 2023Assignee: KUBOTA CORPORATIONInventors: Mitsuhiro Akita, Kazuyuki Chuma, Kohei Sawada, Yukimasa Kabe, Satoshi Inayama, Junya Ikai

Publication number: 20220389355Abstract: The present invention relates to a multicellular construct that includes cells and a scaffold. The scaffold is constituted by a layered composite that comprises a gelatin nonwoven containing gelatin as a main component, and a gelatin film containing gelatin as a main component and layered on one surface of the gelatin nonwoven, and the cells are present in at least one of a region on the surface of the gelatin nonwoven and a region inside the nonwoven. The multicellular construct can be produced by arranging the scaffold in a swollen state inside the culture vessel whose inner surface is in the dry state such that the gelatin film of the scaffold is in contact with the inner bottom surface of the culture vessel, dripping a cell suspension onto the gelatin nonwoven of the scaffold, and then culturing the cells.Type: ApplicationFiled: November 17, 2020Publication date: December 8, 2022Inventors: Kohei SAWADA, Atsushi BABA, Toshiki SAOTOME, Naoki SHIMADA
