Teeth 43 or embossments 44, and adhesive-retaining grooves 45 are formed on inner surfaces of the metal yokes, so the transmission shaft is desirably compression-fitted into the metal yokes. Accordingly, the propeller shaft has advantages of securing improved impact, abrasion, and water resistance.Type: GrantFiled: April 30, 2003Date of Patent: March 8, 2005Assignee: Korea Advanced Institute of Science and TechnologyInventors: Dai Gil Lee, Jin Kook Kim, Hak Sung Kim, Jong Woon Kim

Patent number: 6835263Abstract: An undercritical drive shaft and a method of producing the undercritical drive shaft from fiber composite material is disclosed. The drive shaft, which is produced of fiber composite material and is to be used as an undercritically operating shaft, has a high damage tolerance with respect to resistance to torsion and the manufacturing process requires lower expenditures. For the drive shaft, the fiber composite material consists of several successively individually wound-up webs of prepreg. For the method of producing the drive shaft from fiber composite material, as the fiber material, the web-shaped prepreg is wound onto the winding spindle and this prepreg is deaerated and simultaneously compressed by the winding-on of a thermoplastic woven band which is prestressed in a defined manner. The thermoplastic woven band is unwound again and additional prepreg layers are then wound up which are then deaerated and compressed in the same manner by a thermoplastic woven band.Type: GrantFiled: April 2, 2002Date of Patent: December 28, 2004Assignee: Eurocopter Deutschland GmbHInventors: Anton Bergmann, Marinus Sedlmeier

Patent number: 6818088Abstract: An apparatus and method to fabricate a photosensitive drum for an image forming apparatus. The apparatus includes a photosensitive belt supply roll and a double-sided tape supply roll; a bonding unit to bond a photosensitive belt and a double-sided tape together; a cutting unit to cut the bonded photosensitive belt and double-sided tape at a predetermined length from a double-sided tape cover; a rotating unit to rotate the cut photosensitive belt and double-sided tape around a rotary drum having a predetermined size; and a winding unit to wind the double-sided tape cover which is separated from the photosensitive belt and the double-sided tape. An inexpensive photosensitive belt is wound on a large-sized rotary drum by applying tension. Thus, it is possible to mass-produce the photosensitive drum at a low cost.Type: GrantFiled: July 18, 2002Date of Patent: November 16, 2004Assignee: Samsung Electronics Co., Ltd.Inventor: Jin-Soo Lee

Patent number: 6767422Abstract: A golf club shaft is 35-50 percent lighter than a conventional shaft while maintaining the outer diameter and structural characteristics of conventional shafts. The shaft has at least four layers of fiber reinforced material. The fiber reinforced layers are from innermost to outermost: a first angled layer; a first straight layer; a second angled layer; and a second straight layer. The angled layers are formed by bonding together two materials, each with fibers aligned in different directions. The second angled layer maintains the proper strength and rigidity of the shaft while keeping the shaft as light weight as possible. Aligning the second layer's fibers at an angle of 35-75 degrees with respect to the longitudinal direction of the shaft ensures proper weight and strength characteristics of the shaft. The resulting shaft is light-weight and exhibits the flexural rigidity, flexural strength, torsional rigidity, torsional strength, and crushing strength of conventional shafts.Type: GrantFiled: December 28, 1999Date of Patent: July 27, 2004Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Tetsuya Atsumi, Ikuo Takiguchi, Tsutomu Ibuki, Katsumi Anai

Patent number: 6692377Abstract: An improved golf club shaft is disclosed. The golf club shaft includes a shaft body made of a composite material, such as carbon/epoxy, and a metal foil wrapped in a spiral pattern around at least a portion of the shaft body. The metal foil increases the torsional stiffness of the shaft and improves its bending stiffness, thereby enabling the first and second frequencies of a golf club employing the shaft to remain in a desired range.Type: GrantFiled: December 4, 2002Date of Patent: February 17, 2004Assignee: Callaway Golf CompanyInventor: J.

Patent number: RE38552Abstract: A frame, a drive mechanism for rotating a mandrel, at least two spindles mounted to the frame, a tensioner, and a belt extending between the first and second spindles may be used to roll pre-preg strips or similar sheets of composite materials around the mandrel. The belt travels over the spindles, and the spindles guide the belt through changes in its direction of travel. The mandrel is mounted in the drive mechanism in contact with the belt, which changes its direction of travel around the mandrel. The lower surface of the belt bears against upper portions of the spindles, and the mandrel contacts the upper surface of the belt. As the drive mechanism rotates the mandrel, pre-preg sheets are fed between the mandrel and the belt and are thereby wrapped around the mandrel. The belt presses the pre-preg sheets against the mandrel. The wrapped mandrel may then be removed from the apparatus and cured in any suitable manner known in the art to produce a composite tubular article.Type: GrantFiled: January 30, 2001Date of Patent: July 13, 2004Assignee: Revolution Composites, Inc.Inventors: David H.
