Abstract: A convenient, disposable male urinary aid which allows a man to urinate directly into a toilet from a standing position by channeling the urine directly into water contained in the toilet bowl. A plurality of the urinary aids are formed as a roll of temporarily waterproof two-ply paper resembling conventional toilet paper, with the roll being divided into sheets by perforations. Multi-sheet segments are divided by double rows of perforations, with each multi-sheet segment forming one of the urinary aids with a channel comprising a passageway for liquid being formed between the two plies. Following use, the urinary aid may be flushed down the toilet, since it is made entirely of biodegradeable materials.

Abstract: An apparatus that separates a golf club head and a golf club shaft to which it is adhesively secured. A hosel push member is positioned in abutting relation to the hosel of the club head. An externally threaded guide tube is slideably inserted over the hand grip of a golf club shaft and is positioned in trailing relation to the hosel push member.

Abstract: A method of assembling a two-chamber component includes radially deforming an outer chamber to permit an inner chamber, which includes a fusible plug, to be inserted into the outer chamber. The inner chamber includes a fusible plug that extends radially away from the outside surface of the inner chamber.

By radially deforming the outer chamber, it is possible to insert the inner chamber until the plug is radially and axially aligned with a radial opening in the outer chamber. Once the inner chamber is in proper position, the radial deformation is undone and the plug protrudes through the radial opening in the outer chamber, thereby permitting fluid communication from the inner chamber that is isolated from the contents of the outer chamber.

Abstract: In an induction- and MR-type composite magnetic head of the type that one of two shield films of an MR-type magnetic head serves as one of two cores of an induction-type magnetic head, conductive leads are thicker than an MR element so that steps are formed at the boundaries between an MR element sensitive region and the conductive leads. An upper gap layer has a constant thickness and has a recess 56 on its upper surface because of topographical transfer of the underlying steps. An upper shield--lower core layer has a downward convex at its lower surface, because of topographical transfer of the recess on the upper surface of the upper gap layer. However, the upper surface of the upper shield--lower core layer is flat and parallel to the MR element. Therefore, a write gap layer formed thereon is made flat and parallel to the MR element. Steps of the write gap can be removed and a record density can be increased.

Abstract: An interconnecting post for mounting a microelectronic device such as an integral circuit chip is fabricated with generally uniform cross-section, by forming a first layer of positive photoresist on a substrate, soft-baking that first layer and exposing it for a short time with a wide-apertured mask or simply a UV blank flood exposure. Without developing the first layer, a second layer of positive resist is then applied over the first layer, soft-baked, and then exposed with a narrow-apertured mask. During the soft-baking of the second layer, some of its activator in the photoresist compound diffuses into the exposed portion of the first layer and modifies its solubility in such a way that, when the layers are subsequently developed, the developer partially undercuts the unexposed portion of the first layer to form in the photoresist an opening of generally uniform cross-section. This opening can then be filled by plating to produce a strong, integral interconnect post.
