    摘要: There is described a read/write device which enables realization of miniaturization, a reduction in weight, improvement in the accuracy of step feed, and reliability. The read/write device includes heads, a carriage, a stepper motor for moving the carriage stepwise, and a medium drive motor for spinning a recording medium. The stepper motor further includes a rotor, a first stator which is formed from multilayer magnetic material and is fixedly positioned so as to surround the rotor, a second stator formed in substantially the same way as the first stator, and a holder for housing the first and second stators.

    摘要: An optical branching device includes a main waveguide and a branching waveguide. A portion of the main waveguide is bent and the branching waveguide is placed close to the bent part of the main waveguide. The branching waveguide has a taper structure such that a width of the branching waveguide is gradually decreased in a propagation direction of light. A central axis of the branching waveguide is tilted from a line extended from a straight part of the main waveguide toward the direction X, or the bending direction of the main waveguide. An input end of the branching waveguide has a normal vector tilted from the central axis of the branching waveguide toward the direction Y, an opposite direction of the bending direction of the main waveguide. With above-mentioned structures, light radiated from the bent part of the main waveguide can be launched into the input end of the branching waveguide and transmitted through the branching waveguide efficiently.

    摘要: An electron emission device exhibits a high electron emission efficiency. The device comprises an electron supply layer of metal or semiconductor, an insulator layer formed on the electron supply layer, and a thin-film metal electrode formed on the insulator layer. The electron emission device emits electrons when an electric field is applied between the electron supply layer and the thin-film metal electrode. The insulator layer is a dielectric layer having a thickness of 50 nanometers or more, and formed by a vacuum evaporation process with a layer forming rate of 0.5 to 100 nanometers/minute.

    摘要: A compact voltage sensor with stable characteristics is provided. A measuring beam that is incident from an optical fiber is branched into first and second modulation-inducing waveguides of a wave branching/combining section within an optical integrated circuit. Phase changes of opposite sign are induced in the measuring beams propagating within the first and second modulation waveguides by applying voltages of mutually opposite sign to modulation-inducing electrodes, to induce a phase difference between the two. By reflecting the measuring beams from a reflective surface, propagating them back in the opposite direction within the first and second modulation waveguides, and passing them through the optical intensity modulation section again, thus applying a further phase modulation thereto, the phase difference between the measuring beams proceeding in the opposite direction within the first and second modulation waveguides can be made to be substantially twice the phase difference of the measuring beams before they are reflected by the reflective surface. The sensor also has a function to protect a sensor section thereof from dielectric breakdown caused by the accidental input of a high voltage.
