Patent number: 10704435Abstract: A breather device for an engine which prevents a blow-by gas outlet passage from being blocked due to freezing, is provided, which includes a valve holder in a cylinder head cover and a breather valve supported by the holder. The holder includes a holder body having a valve port of the breather valve, a metal outlet passage pipe having a blow-by gas outlet passage formed inside, the blow-by gas outlet passage communicating with the valve port and being located below the valve port, and a heater that heats the outlet passage pipe. An outer peripheral surface of the outlet passage pipe is wrapped with the holder body formed of a material having lower thermal conductivity than that of the outlet passage pipe. The holder body has a heater insertion port, and the heater is inserted from the heater insertion port toward a heat input wall of the outlet passage pipe.Type: GrantFiled: May 24, 2018Date of Patent: July 7, 2020Assignee: KUBOTA CorporationInventors: Gen Nakamura, Koji Okada, Tamotsu Kuno, Akihiko Kai

Patent number: 5937527Abstract: A blade holder attached to a saw handle. The saw blade includes a slot on one side, and is engaged inside the blade holder and is securely held in place by stoppers formed inside the holder's frame and by pressure applied by spring action. This spring action is created via a turning of a knob and attached pressing part and protrusion. When the knob is in a loosened position, the blade is easily removed and replaced through a holder receiving part. A new blade is received through the receiving part and by tightening the knob, the new blade is thereby secured in the holder.Type: GrantFiled: September 22, 1997Date of Patent: August 17, 1999Assignee: Kabushiki Kaisha Okada KinzokuInventor: Tamotsu Okada
