    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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. Under one embodiment, the source, drain and gate may be stimulated at any voltage level from ground to supply voltage, and wherein the two control terminals are stimulated at any voltage level from ground to a switching threshold voltage larger in magnitude than the supply voltage. Under one embodiment, the nanotube switching element includes an article made from nanofabric that is positioned between the two control terminals. Under one embodiment, one of the two control terminals is a release electrode for electrostatically pulling the nanotube article out of contact with the one of the source, drain and gate so as to form a non-volatile open state. Under one embodiment, the other of the two control terminals is a set electrode for electrostatically pulling the nanotube article into contact with the one of the source, drain and gate so as to form a non-volatile closed state.

    摘要: A clasp is described that is lockable in both an open and a closed position. In the locked open position the clasp can be manipulated without concern for the clasp unintentionally closing before it can receive the end of a chain, such as a necklace or the like. Pushing a button on the clasp closes and locks the clasp. The clasp remains locked in the closed position until the button is pressed and the clasp is pulled open.
