Patent number: 7013716Abstract: A surface capacity parameter is determined for a surface of an article having irregularities therein that can be characterized by peaks and valleys relative to a reference point. Initially, an area of interest on the surface of the article and a lateral resolution of that area of interest are determined. An apparatus generates a visual representation of the area of interest on the surface of the article. A deflection contact part factor for the article is calculated, and a bearing ratio curve level is determined based upon the calculated deflection contact part factor and the magnitude of the height or distance between the tallest peak and the lowest valley on the surface of the article. The volume of the material comprising the peaks in the surface of the article and the volume of the space in the surface of the article that is available for the retention of a fluid, such as a lubricant, are determined.Type: GrantFiled: July 29, 2002Date of Patent: March 21, 2006Assignee: Dana CorporationInventors: Mark Shuster, Donald K.

Patent number: 6865927Abstract: A micro-object having a desired sharp point or edge may be optically tested during fabrication.

The peel and stick adhesive base 20 will maintain the cleaning detector 10 in place and the user will put the malleable flap 12 into a substantially perpendicular position relative to the base portion 14. The malleable flap 12 will be deformed away from the substantially perpendicular position if the area proximal to the present invention 10 has been properly swept, mopped, dusted, etc.Type: GrantFiled: August 30, 2001Date of Patent: November 18, 2003Inventor: Eric Downing

Patent number: 6637278Abstract: A measuring system has a freely movable measuring instrument and a computer for processing the measured data. Two measuring devices are in the measuring instrument, each with two acceleration sensors. Two of the sensor each in a common plane and the two measuring planes are at right angles to one another. A measuring wheel is in the measuring instrument for acquiring the length of the displacement path of the measuring instrument. The measuring instrument acquires the shape and length of a surface line of a body and its representation in two spatial planes with a measuring range from 0 to 360° in one plane. Input elements and a display arrangement on the measuring instrument serve to simplify the measuring process and permit direct control and monitoring of the measuring process.Type: GrantFiled: August 2, 2001Date of Patent: October 28, 2003Assignee: IdiagInventor: Piero Fasanella

Patent number: 6609415Abstract: A test piece made of a material equal to the material of the workpiece is formed in a size that permits the test piece to be housed in an adsorption tube container mounted to a mass analyzing apparatus of a gas chromatograph. The test piece is left to stand for a predetermined time in a measuring site of the atmosphere within a cleansing chamber and, then, recovered. The recovered test piece is introduced into a mass analyzing apparatus of a gas chromatograph (GC-MS apparatus) for measurement of the material of the contaminant and the mass of the contaminant, thereby evaluating the degree of contamination of the measured point.Type: GrantFiled: March 9, 2001Date of Patent: August 26, 2003Assignee: Hitachi Plant Engineering & Construction Co., Ltd.Inventors: Syuichi Ishiwari, Haruo Kato

Publication number: 20030110843Abstract: The invention relates to a measuring sensor (1) for measuring positive and negative elongations on cylindrical or profiled bodies (6). The measuring sensor (1) consists of more than two parts and is essentially annular and has at least one tensioning element (7, 15). Two segments (2, 3) that can be tensioned are provided with a recess on the longitudinal center on the internal contour (22), the recess being disposed opposite the direction of tensioning (S) and accommodating a protruding elastic element (8) with a measuring element (10). The recesses can be pressed non-positively onto the surface of the body (6). The segments (2, 3) of the multi-part measuring sensor (1) that are diagonally opposite can be tensioned with their both ends by means of exchangeable and/or adjustable lateral guide members (4, 5, 26, 38) for the body to be measured (6).Type: ApplicationFiled: October 29, 2002Publication date: June 19, 2003Inventor: Matthias Tanner

Patent number: 6568252Abstract: Disclosed is a method for testing the smoothness of a disc surface. A glide test is performed by first lowering the glide head until contact between the glide head and the disc surface occurs. The point of contact establishes a base line indicating the location of the disc surface. Once a base line is established, the glide head can be controlled so that it flies at the desired glide height above the disc surface. By first establishing the base line, the glide head can be flown with greatly increased precision at the desired glide height based on known relationships between glide height and various parameters, including spindle speed, various electrical parameters, or crown shape.Type: GrantFiled: July 10, 2001Date of Patent: May 27, 2003Assignee: Seagate Technology LLCInventor: Zine-Eddine Boutaghou

Patent number: 6566653Abstract: An investigation device includes a time of flight mass spectrometer with an entrance opening, and an electrically conductive tip on a cantilever which is movable from a first position near a sample on a sample holder to a second position near the entrance opening. A sample particle is obtained with the tip being in the first position from the sample. The tip, with the particle, is moved into the second position where the particle can be accelerated towards the entrance opening. The particle is analyzable by the time of flight mass spectrometer.Type: GrantFiled: January 23, 2002Date of Patent: May 20, 2003Assignee: International Business Machines CorporationInventors: Christoph Gerber, Michel Despont, Peter Vettiger, Ernst Meyer, Roland Bennewitz
