Title: Hammer
Inventor: SUMIYA KATSUMI
IPC: B25D1/00
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To increase striking force when a hammer is swung down so as to reduce worker's sense of fatigue in the hammer striking work by incorporating a weight having desired weight in a grip handle part from a section on striking head part side to a rear end part so as to travel and displace. SOLUTION: A slide guide hole 4 is linearly provided in a grip handle part 3 from a front head part to substantially rear end part thereof, and a weight 5 is provided in the slide guide hole 4 so as to travel and displace. When a worker grips a grip part 3b of the grip handle part 3 and swings down a hammer 1 itself from a state in which the hammer itself is swung up in the striking work by the hammer 1, the weight 5 is moved and displaced in the slide guide hole 4 of the grip handle part 3 from a rear end side to a section on a striking head part 2 side due to the motion. Since a weight (mass) of the weight 5 is added to the striking head part 2 side due to the travel and displacement of the weight 5, strong striking force can be obtained together with the striking head part 2 and swinging down force.

Title: Method for preventing wrinkle on inner surface at pipe casting
Inventor: KUBOTA KAZUO
IPC: B22D13/02
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent the development of wrinkle on the inner surface even in the case of forming pipes of large inner diameter and middle inner diameter with a centrifugal casting method by supplying a combustible material into a molten iron at the solidifying stage after pouring the necessary quantity of molten iron into a rotating metallic frame, burning it and heating the inner surface. SOLUTION: The molten iron 10 is poured into the rotating metallic frame 1 from a trough 3, after passing 0-20 sec from the completion of pouring the necessary quantity of the molten iron, coke breeze 5 is blown on at 0.10-0.20% ratio to the iron tube weight. At this time, since the metallic frame 1 is rotated and the coke breeze 5 is reflected with a back metal band 1c surface, the coke breeze is diffused as uniform dispersion state into the formed tube and burnt. Therefore, the inner surface of the tube is heated with the combustion heat of the coke breeze 5 and the solidification of the molten iron is delayed for a while.  In this way, the solidification starts from the outer surface of the tube and at the stage of progressing the solidification into the inner surface, since the inner surface is heated at the timing easily developing the wrinkle on the inner surface so as not to be solidified yet thereat, the development of the wrinkle is prevented.
