Abstract: A semiconductor device under test (DUT) is checked, particularly for its wirebond integrity, by comparison with an identical reference device which is known good. Each of the DUT and reference device equally has pins. A current is selectively supplied to each pin of the reference device to provide a reference voltage drop at the reference device. Similarly, an identical current is selectively supplied to each pin of the DUT to measure a voltage drop at the DUT. The voltage drop at the DUT is compared with the reference voltage drop to provide a difference. Finally, determination is made as to whether the difference is within a tolerable range.

Abstract: Cards and methods of securing hidden symbols on cards are disclosed. The cards, such as instant-win lottery tickets, utilize continuous overprint inks that mask the boundaries between their "secure" and "unsecure" portions to inhibit unscrupulous players from successfully tampering with them. By reformulating the overprint inks to permit a single set to be applied to both portions of a card, more vibrant and aesthetically-pleasing graphics may be displayed as well while utilizing fewer printing stations during the printing process.

Abstract: A takraw ball having a relatively soft, or elastically deformable, surface and conventional rebound characteristics. The takraw ball may be woven from composite strips, one component of which is elastically deformable material and forms the ball surface and the another component of which is a springy material. The elastically deformable material and the springy material are selected to produce a desired rebound characteristic. The strips have a wide variety of shapes and compositions. In an alternative embodiment the springy material component forms the ball surface and the elastically deformable material provides reinforcement for the strip.

Abstract: A screw tensioning device is proposed for holding at least one end of a ligament graft. The device has a thimble (1) which locates in the mouth of a drilling through bone, a nut (2) captively seated in the thimble, and an anchorage element (3) with a screw threaded stud (12) which can engage the nut. Different forms of anchorage elements are provided for different grafts, but each is adapted to securely hold one end of a ligament graft. The anchorage element (3) with a ligament attached is drawn through the drilling from the opposite side to the thimble (1) until the stud (12) engages the nut (2). The nut is then turned by a tool (19) until the required tension is achieved.

Abstract: An abrasive blasting apparatus is provided which comprises a blast nozzle arranged in a blast chamber for blasting, toward a workpiece, two different kinds of abrasive particles separately supplied from a first abrasive container and a second abrasive container.

The bearing includes a bearing pad structure that may change shape and move in any direction (six degrees of freedom) to optimize formation of a converging wedge for hydrodynamic operation, equalization of load on the bearing pads in thrust bearings and to adjust for any shaft misalignment. The bearing pad may be formed so as to contact the shaft in the installed state and to deflect under fluid film pressure. The shape of the pads may be altered to achieve desired deformations under load. The pads are supported by a support structure which can include one or more beam-like members. The support structure preferably includes a primary support portion, a secondary support portion and a tertiary support portion.

Wheels may also be formed of a compressible elastomeric material.
