Abstract: Non-volatile field effect devices and circuits using same. A non-volatile field effect device includes a source, drain and gate with a field-modulatable channel between the source and drain. Each of the source, drain, and gate have a corresponding terminal. An electromechanically-deflectable, nanotube switching element is electrically positioned between one of the source, drain and gate and its corresponding terminal. The others of the source, drain and gate are directly connected to their corresponding terminals. The nanotube switching element is electromechanically-deflectable in response to electrical stimulation at two control terminals to create one of a non-volatile open and non-volatile closed electrical communication state between the one of the source, drain and gate and its corresponding terminal. Under one embodiment, one of the two control terminals has a dielectric surface for contact with the nanotube switching element when creating a non-volatile open state.

Abstract: The present invention relates an arrangement and a process for making the arrangement that comprises a tampon, an applicator unit, and a uniformly shaped film cap. The tampon has a withdrawal end opposed to an insertion end, the insertion end having a top portion. The applicator unit contains at least a portion of a tampon and has a bottom side opposed to a topside. The film cap is uniformly shaped and covers at least a portion of the top portion of the tampon and attaches to at least a portion of the applicator unit. The arrangement is obtainable by a process comprising the steps of attaching the planar film to the applicator and shaping and or stretching the planar film to create a film cap.

Abstract: The present invention relates to a wrapper for individually packaging absorbent articles for personal hygiene, especially tampons. The wrapper of the present invention is provided with an opening means, which prevents the wrapper from becoming separated into more than one piece of wrapper material upon being opened.

Abstract: Shaped tampons having varying perimeters are provided. Tampons disclosed comprise a mass of absorbent material formed into a self-sustaining shape comprising an insertion end, a withdrawal end, and a center region. The center region has at least one perimeter which is less than a largest insertion end perimeter and is less than a withdrawal end perimeter. The shaped tampons may also have varying average fiber density regions. The shaped tampons may be wrapped in tightly conforming wrappers which optionally aid in maintaining the self-sustaining shape prior to use. Optionally, the shaped tampons may utilize tampon applicators which enable a user to visually see the shape of the tampon prior to use.

Abstract: An optical recording head is provided which includes a slider body having a leading edge. A void is formed in the slider body to receive a sphere of optically transparent material. The sphere is inserted into the void such that a portion of the sphere protrudes from the slider body. The protruding portion is lapped to be coplanar with a surface of the slider body to form a near-field lens. A mesa may be formed onto the lapped portion and may include a coil. The slider body, mesa, near-field lens, and coil may be formed in one batch process.

Abstract: Devices and techniques for placing and bonding identical elements to holes in a substrate where spacer balls and a reference surface are used to achieve the desired accuracy.

Abstract: Shaped tampons having varying volumes are provided. A tampon which is formed into a self-sustaining shape has an outer surface, which is substantially serpentine. The tampon also has continually changing volume. The shaped tampons may also have varying average fiber density regions. The shaped tampons may be wrapped in tightly conforming wrappers which optionally aid in maintaining the self-sustaining shape prior to use. Optionally, the shaped tampons may utilize tampon applicators which enable a user to visually see the shape of the tampon prior to use.

Abstract: A tampon applicator including an elongate insertion member having a length extending from an insertion end to a gripper end opposite thereof. The gripper end has a grip region dimensioned to substantially accept a user's grip. The grip region has a plurality of corrugations, a first transition portion, and a second transition portion. Each corrugation has a trough and a ridge. The first transition portion is substantially adjacent the gripper end and a second transition portion is disposed toward the insertion end.

Abstract: The present invention relates to a tampon applicator arrangement, having tampon, applicator unit and a film cap, attached thereto, which is at least partially uniformly shaped, typically being conforming to part or all of the tampon or applicator unit, or such that the film cap has the lowest possible surface area. The film cap is so shaped and/or generally under tension and has no rugosites, folds or even wrinkles, other than optionally tension wrinkles, and preferably also no seams or welds. The invention also relates to specific moulding processes for making the film cap and the arrangement of the invention. The arrangements of the invention provide a smoother, easier and safer insertion of a tampon in the body.

Abstract: A monolithic optical head facilitates reading and writing optical data on an optical recording medium. The optical head includes a monolithic substrate formed of an optically transparent material. The substrate has a first side and a second flat side opposing the first side. The first side includes a central region that has a curved surface to produce a lensing effect, and a peripheral region. The second flat side has a central portion opposing the curved surface to couple radiation from and to the curved surface through the substrate. The second flat side also has a peripheral portion opposing the peripheral region of the first side.

Abstract: Optical heads having a monolithic layer for interfacing storage media and methods for manufacturing such heads. In one embodiment, the substrate has first and second surfaces to define a through hole which forms an optical path and a lens with a spherical surface and a flat surface opposing the spherical surface is disposed in the optical path in the through hole. The flat surface is coplanar with a flat portion of the second surface. The optical head also includes a transparent layer contiguously formed over both the flat surface of the lens and the second surface of the substrate to form a monolithic layer. The refractive index of the additional layer may match that of the lens. In addition, the additional layer may have a material hardness greater than that of the lens to protect the lens and to reduce wear.
