Abstract: A spinning reel for fishing, having an improved braking drag regulating structure, which is provided with a locking stoper on the portion of a reel casing over which an operating lever is moved forward and backward, and a locking member formed on the operating lever and adapted to be engaged with the stopper and thereby lock the operating lever, either of the stopper and locking member being made movable so that these two parts can be released from the engaging force. Therefore, the range of pivotal movement of the operating lever can be changed instantly with ease from a wide range to a narrow range, and vice versa. This braking drag regulating structure can prevent the occurrence of both the breakage and the slackening of a fishline.

Abstract: A method for arc welding a very low carbon steel containing 0.005-0.06% C characterized by employing a welding material with nickel together with high carbon so as to form weld metal containing nickel. Solidification cracking on the thus welded metal can be prevented.

Abstract: A pot lid adaptable to a cookpot for boiling down foods such as fish, meat and the like. The pot lid has a plate having a contour adaptable to the cookpot, and a cover detachably installed on an upper surface of the plate. The plate has a threaded hole at its center, openings for releasing steam and grooves which extend to the circumferential end of the plate. The cover has a diameter large enough to close the openings and a rod projecting downwardly. The rod has a threaded groove at its end portion with an ungrooved portion being left above the threaded groove. The threaded groove is engageable with the threaded hole of the plate. When in use, the ungrooved portion of the rod is slidably held within the threaded hole of the plate to permit a heated broth of the boiled foods to discharge from at least the openings.

Abstract: A method and apparatus are provided for extruding a tubular article in which a mandrel, over which the article is drawn, has a groove on the outer surface thereof and an aperture in the groove. As the tubular article is drawn over the mandrel and in contact therewith, air between the tubular article and mandrel is forced into the groove and discharged through the aperture.

Abstract: An apparatus is provided, in which a vegetable is rotated whereas a blade is reciprocated under pressure on the vegetable, to form a tape-like flesh which is used for various kinds of dishes.
