Abstract: An integral stamped ball joint housing for use in a vehicle suspension system. The ball joint housing may be stamped as part of the suspension system control arm thereby forming an integral control arm or may be inserted into an aperture of the control arm. The ball joint housing is stamped from a single piece of raw steel stock to form the housing according to end specifications. The process of manufacturing the stamped on-piece ball joint housing includes sequentially drawing the parent material to form the basic ball socket and thereafter sizing the outer and inner diameters of the housing to the desired configuration.

Abstract: A method for forming a three-dimensional object by applying segments of complementary material and deposition material so as to form layers of material. Selected segments of material are then shaped after one or more segment is formed. In this manner, layers of material form a block containing the object made of deposition material and surrounded by complementary material. Then, the complementary material which serves as a support structure during forming is removed. Preferably, the complementary material has a lower melting temperature than the deposition material and is removed by heating the block. The deposition material and complementary material are preferably applied by thermal spray deposition but may be applied by weld deposition, liquid slurry, gravity drop or any manual means such as a hand sifter. It is also preferred but not necessary to use masks when applying the material.

Abstract: An apparatus (1) for routing a passageway in a conduit includes an elongate cable (18) for direction into a conduit passageway. A cable supply drum (16) contains a supply of the cable (18) and is rotatable about an axis (28), there being a length of the cable (18) projecting out of the drum (16). A motor (14) selectively imparts rotation to the drum (16) about the axis (28). The cable (18) and drum (16) are configured such that the projecting length of cable (18) rotates about its length as an incident of the drum (16) being rotated about its axis (28). A brake (60) is provided for stopping rotation of the drum (16) and thereby rotation of the projecting length of cable (18) so as to prevent torquing of the projecting length of cable (18) when the projecting length of cable (18) is prevented from freely rotating by an obstruction encountered in the conduit passageway.

Abstract: A grazing incidence interferometer (1) includes a laser (10) and a beamsplitter (16) for splitting an output of the laser into a reference beam (B) and into a sample beam (A). A surface (18) to be examined is disposed at a first angle such that the sample beam is incident on and reflects from the surface at an angle of incidence other than normal, thereby providing a grazing incidence configuration. A beam combiner (22) combines the reference beam and the sample beam that reflects from the surface into a combined beam (C). An image plane (24) is disposed for receiving the combined beam such that an interference pattern is formed at the image plane. The image plane is disposed at a second angle to the combined beam, the second angle being selected to compensate for a reduction in an aspect ratio of the interference pattern that results from the surface being disposed at the first angle. The second angle may be approximately equal to the first angle, or may differ from the first angle to obtain a desired aspect ratio.

Abstract: An apparatus ( 40 ) for providing consistent, non-jamming registration of a semiconductor wafer ( 46 ) undergoing process work includes a plate ( 42 ) upon which the wafer ( 46 ) is laid flat. A flat ( 45 ) of the wafer ( 46 ) is registered against two rollers ( 43' ) that are fixedly mounted to the plate ( 42 ). A third roller ( 43 ), also fixedly mounted to the plate ( 42 ), registers a first point ( 47 ) along the circumference of the wafer ( 46 ). A fourth roller ( 48 ) is fixedly mounted to a bracket ( 50 ) that is movable approximately along the radius of the wafer ( 46 ). A force ( 54 ) is applied to this bracket ( 50 ) resulting in the fourth roller ( 48 ) applying a force against the wafer ( 46 ). This resultant force, coupled with the rotating capability of the rollers ( 43 ,  43' ,  48 ), allows the wafer ( 46 ) to rotate into a proper registration position. A second embodiment ( 60 ) that incorporates essentially these same force and rotation dynamics through the use of flexures ( 64 ,  66 ,  68 ) is also disclosed.

Abstract: A data storage system comprises magnetoresistive (MR) sensing elements for sensing data from a recording medium that is referenced to ground, and an amplifier circuit including a biasing stage, an amplifying stage, and a matching stage, each referenced to a common supply voltage source and to ground. The biasing stage includes a reference current source for selectively biasing each MR element with a constant current and, in so doing, developing a single-ended voltage signal having a first dc component. The amplifying stage converts the single-ended voltage signal into an amplified single-ended output voltage signal having a second dc component but in which the first dc component is eliminated. The matching stage creates a bias and imposes said bias on the amplifying stage for converting the single-ended output voltage signal to a differential output voltage signal in which the second dc component is eliminated.
