An improved process for electroplating bonding pads, such as of gold, onto semiconductor devices is disclosed. Upon electrically connecting a masked semiconductor body and a suitable anode to the negative and positive terminals respectively of a power supply and submerging the wafer and anode into a suitable electrolyte, a modulated, rather than direct, current is applied to the electrolyte. A low stress, fine grain bonding pad layer is provided and, unexpectedly, non-planarities in the semicond...

An improved bearing assembly supports a pair of parts for movement relative to each other. The bearing assembly includes a plurality of rotatable bearing elements such as rollers, which engage raceways on the parts. The bearing elements are disposed in openings formed in a longitudinally extending cage member which separates the bearing elements. The cage member is supported by wear pads which engage at least one of the raceways. The bearing elements roll along a central portion of the raceway. ...

Breast pads, cups and fronts for use in brassieres and other garments are molded from a thin, generally planar blank of an open-cell or closed-cell polymeric foam material (e.g. polyurethane). The blank is placed between mold parts and the male mold part then deforms the blank into the configuration of the female mold part while negative pressure is exerted on the female mold part, thereby causing the blank to be seated in the configuration of the female mold part. The male mold part is then wit...

A suction pad for adhering a load to a surface and comprising a disc having an extensible annular seal on one face and a radial vacuum inducer mounted on the other. The inducer is capable of evacuating the interior region bounded by the seal to anchor the disc to the surface. There are gas thrusters disposed outside the seal for opposing the vacuum by extending the seal when it is required to reduce adhesion to allow lateral displacement of the suction pad without breaking the annular seal.

A protective pad for use in cushioning the body has a resilient organic foam polymeric material with body cushioning properties. The pad has an undersurface facing the body and a scored top surface forming an increased flexibility in the pad to better enable it to conform to the joint or other body area which it is protecting. This increased flexibility and body conforming property is obtained without substantial loss of body cushioning and protective properties.

A novel keyboard switch covering pad suitable for use in, for example, a pocketable electronic calculator is proposed which is safe from the danger of failure or erroneous operation of the LSI or other electronic devices built in the instrument when two or more of the key switches are pushed simultaneously. The keyboard switch covering pad of the invention comprises an electrically conductive rubber sheet divided into a desired number of sections and an electrically insulating sheet which serves...

Timely testing of die on wafer reduces the cost to manufacture ICs. This disclosure describes a die test structure and process to reduce test time by adding test pads on the top surface of the die. The added test pads allow a tester to probe and test more circuits within the die simultaneously. Also, the added test pads contribute to a reduction in the amount of test wiring overhead traditionally required to access and test circuits within a die, thus reducing die size.

A plurality of elongated lead-in electrodes are hermetically sealed in a wafer of metal oxide varistor material and extend therethrough. The portions of the wafer in contact with said electrodes are spaced to provide a current flow between the electrodes which is low when normal operating voltage appears across the electrodes and when voltages in excess of normal voltage appear progressively thereacross a rapidly decreasing impedance is presented by the wafer in accordance with the alpha of the ...

An electrically heated pad or blanket having two heating elements defining two separate electrical circuits, each circuit being connected to a multi-position switch so that they can be connected to a supply of electricity in series or parallel or selectively one at a time, one of the heating elements being longer than the other and having the greater length part disposed in a region not containing the runs of the shorter element so that when placed in parallel there is an even heat distribution ...

Internal pads of sponge material are preferably enclosed in a fabric casing and secured to the inside surface of rubber boots or shoes. The construction permits the wearer to put his feet into the boots without strenuous effort. Also, the boots may be removed easily without using a zipper opening or shoe laces. While being worn, the wearer may run or take long walking steps without fear of losing the boots or of displacing the foot within the boot. The sponge inserts hold the foot in its proper ...
