Patent number: 5719077Abstract: The invention is an apparatus and method for cleaving a semiconductor bar and coating the cleaved facets within a vacuum environment. The apparatus is a fixture having at least one rotator for cleaving one or more semiconductor samples into semiconductor bars and positioning the semiconductor bars for immediate coating of their cleaved facets. The fixture is operably positioned within a processing chamber and exposed to a conventional coating medium before, during or immediately after cleaving the semiconductor sample. The fixture cleaves the semiconductor samples in a manner that reduces semiconductor sample waste and also allows the processing environment requirements to be reduced compared to other cleaving and coating techniques. A single actuation feed-through mechanism actuates the fixture from outside of the processing chamber.Type: GrantFiled: October 30, 1995Date of Patent: February 17, 1998Assignee: Lucent Technologies Inc.Inventors: Utpal Kumar Chakrabarti, Judith Francavilla de Jong, Erdmann Frederick Schubert, James Dennis Wynn, George John Zydzik

Patent number: 5699947Abstract: According to the invention, parting of the cap of the connecting rod is achieved by engaging the eye of the big end of the connecting rod with two semicylindrical fixtures, respectively a fixed fixture and a movable fixture, which are actuated by a hydraulic actuator which is interposed between them and is adapted to expand the fixtures in a diametrical direction against the inner surface of the eye of the big end of the connecting rod, subjecting the piston of the actuator to the action of a hydraulic fluid fed into the respective actuation cylinder at an optional pre-loading pressure that is in any case lower than the pressure required to reach the yield point of the material of the connecting rod, and producing an instantaneous peak in the pressure of the fluid fed to the hydraulic actuator by means of an auxiliary piston that is subjected to the momentary action of a striking mass.Type: GrantFiled: October 10, 1995Date of Patent: December 23, 1997Assignee: Vigel S.p.A.Inventors: Giorgio Cavallo, Gian Luca Giovanelli, Marco Martinis

Patent number: 5568891Abstract: Apparatus for fracturing a powder metal bearing support having stress risers to initiate cracking along a cracking plane. The apparatus has (a) a fixture assembly for holding one internal side of the bearing stationary, and (b) structure for fracturingly pulling a second internal side of the bearing away from the one internal side along a track in a direction substantially perpendicular to the cracking plane.Type: GrantFiled: May 2, 1994Date of Patent: October 29, 1996Inventors: Peter Y. Hoag, David A. Yeager

Patent number: 5495972Abstract: A method of cutting a flat tube (6) into unit pieces, which includes moving in a transverse direction rotatable disc cutters (12) with knife edges so as to cut the upper and lower walls of a flat tube to form a pair of cutting grooves (15) and fixing the flat tube at a point upstream of the cutting groove while flexing in the vertical direction a length of the flat tube downstream of the cutting grooves to break it off at the cutting grooves, thereby providing a unit piece of a predetermined length.Type: GrantFiled: November 29, 1994Date of Patent: March 5, 1996Assignee: Zexel CorporationInventors: Kunihiko Nishishita, Takashi Sugita

Patent number: 5472126Abstract: Method and apparatus is disclosed for severing flat tubing. A length of tubing is gripped at longitudinally spaced apart locations and the tubing is deeply scored by rapidly rotating circular cutters which are moved across the faces of the tubing at a predetermined linear velocity. The angular velocity of the circular cutters greatly exceeds the linear velocity of traversal. An axial force is applied to separate the tubing.Type: GrantFiled: December 16, 1993Date of Patent: December 5, 1995Assignee: Crown Unlimited Machine, Inc.Inventors: Steven L. Stroup, Sr., Steven L. Stroup, II

Patent number: 5450668Abstract: Method and apparatus for separating thin-walled flat metal tubing are disclosed. The tubing has flat upper and lower walls joined by end walls. The tubing is partially severed by providing relative movement between the tubing and opposed cutting blades having straight or slightly curved cutting edges. The relative movement is transverse to the longitudinal axis of the tubing, and the straight slicing edges, or the chords of curved slicing blades, form a small acute angle with respect to the flat faces of the tubing. The tubing is completely severed by applying an axial force to the tubing. Pressing heads follow the slicing blades to press any burrs back into the tubing.Type: GrantFiled: December 21, 1993Date of Patent: September 19, 1995Assignee: Crown Unlimited Machine, Inc.Inventor: Steven L. Stroup, Sr.
