Patent number: 7658238Abstract: An impact drill for boring a workpiece includes a main frame, a motor housed in the main frame, a spindle movably supported by the main frame and rotatable by the motor and movable in its axial direction, a first ratchet positioned fixedly with respect to the spindle, a second ratchet positioned with respect to the first ratchet, a spring biasing the second ratchet toward the first ratchet. The spring has at least one of a spring constant and a biasing force which prevents the second ratchet and the spindle from abutting against the main frame at least one of when a force ranging from 15 to 25 kg is applied to the main frame for boring the workpiece and when the spindle is moved to a retracted position.Type: GrantFiled: August 6, 2004Date of Patent: February 9, 2010Assignee: Hitachi Koki Co., Ltd.Inventors: Jyunichi Toukairin, Kenji Kataoka, Kazuhide Ohzeki, Takuma Saito, Shinki Ohtsu, Shigeru Ishikawa, Hideki Watanabe

Patent number: 7648589Abstract: A method for making a ductile and porous shape memory alloy (SMA) using spark plasma sintering, and an energy absorbing structure including a ductile and porous SMA are disclosed. In an exemplary structure, an SMA spring encompasses a generally cylindrical energy absorbing material. The function of the SMA spring is to resist the bulging of the cylinder under large compressive loading, thereby increasing a buckling load that the cylindrical energy absorbing material can accommodate. The SMA spring also contributes to the resistance of the energy absorbing structure to an initial compressive loading. Preferably, the cylinder is formed of ductile, porous and super elastic SMA. A working prototype includes a NiTi spring, and a porous NiTi cylinder or rod.Type: GrantFiled: September 8, 2005Date of Patent: January 19, 2010Assignee: University of WashingtonInventors: Minoru Taya, Ying Zhao

Patent number: 7364145Abstract: The present invention relates to the design and fabrication of flexures used to guide motion in mechanical systems. A high specific stiffness flexure includes two narrow and thin flexing sections separated by a longer stiffened section. The present invention provides designs and processes for making flexures and flexure systems with monolithic high specific stiffness frame or box structures for the stiffened sections that creates relatively higher self-resonant frequencies.Type: GrantFiled: July 19, 2006Date of Patent: April 29, 2008Assignee: Equipment Solutions, IncInventors: Jeffrey G. Knirck, Paul A. Swanson

Publication number: 20080036125Abstract: In a central fastening element for an axially symmetric, vehicle gas spring, which includes a bellows that has central bores or cutouts in the region of its end faces, the fastening element being fixed to the vehicle body, protruding from the surroundings of the attachment point in a direction normal to it, and being encompassed by the bores or cutouts. The fastening element includes a shaped stud or a shaped cap, the maximum outer diameter of the stud or the cap being at least less than one fifth of the maximum outer diameter of the gas-spring bellows. A device may be provided which allows a gas spring to be installed in a simple manner and allows the spring bellows to rotate with respect to the suspension and/or the vehicle body during the initial installation and/or the initial operation.Type: ApplicationFiled: January 29, 2002Publication date: February 14, 2008Inventors: Ludger Burstedde, Michael Guse, Andreas Opara, Christian Ottawa, Hans Scheerer
