Patent number: 7479252Abstract: A method for manufacturing a throwaway tip is presented in which a green compact Q obtained by press-forming raw material powder for the throwaway tip is placed and sintered on a sintering plate 8. The green compact Q is press-formed so that the density of the raw material powder is gradually decreased toward a predetermined direction R, and the direction R is oriented substantially toward the outer circumference of the sintering plate 8 in plan view. Thus, it is possible to obtain a throwaway tip having sintering accuracy.Type: GrantFiled: March 26, 2004Date of Patent: January 20, 2009Assignee: Mitsubishi Materials CorporationInventors: Yoshikazu Okada, Toru Narita, Shinsuke Fujisawa

Patent number: 6988563Abstract: A hammer drill is equipped with a connector shaft, which is rotationally driven by a motor, a spindle that transmits the rotation through a connector shaft, and a percussive impact impact mechanism that applies a percussive force in the axial direction to a drill bit held by the spindle through performing a reciprocating motion, in the axial direction, relative to a spindle that receives the rotation of the connector shaft through a motion converter mechanism. The hammer drill is provided with a percussive force converter from the percussive impact impact mechanism by changing the speed reduction ratio between the motor and the connector shaft. This makes it possible to adjust the percussive force according to the drill bit used.Type: GrantFiled: August 26, 2003Date of Patent: January 24, 2006Assignee: Matsushita Electric Works, Ltd.Inventors: Kouichi Hashimoto, Masahide Shiratani, Mineaki Yokoyama, Yoshikazu Okada
