  • Patent number: 10720258
    Abstract: A method for manufacturing a conductive wire includes conducting a continuous casting of a conductive alloy material at a casting rate of not less than 40 mm/min and not more than 200 mm/min to form a conductive wire with a primary diameter, the conductive alloy material containing not more than 1.0 mass % of an added metal element, reducing a diameter of the conductive wire with the primary diameter to form a conductive wire with a secondary diameter, heat treating the conductive wire with the secondary diameter so that tensile strength thereof is reduced to not less than 90% and less than 100% of tensile strength before the heat treating, and reducing a diameter of the conductive wire with the secondary diameter and the reduced tensile strength to generate a logarithmic strain of 7.8 to 12.0 therein to form a conductive wire with a tertiary diameter.

  • Patent number: 10704435
    Abstract: 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.

  • Patent number: 5937527
    Abstract: 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.
