An apparatus for forming an optical aperture comprises an object having a tip with a pointed end. Stoppers are disposed adjacent the tip. A pressing body applies a loading force to press the pointed end of the tip and at least a part of each of the stoppers to form an optical aperture at the pointed end of the tip. A load controller controls the loading force applied by the loader.

In a steering device 10, the upper side portion of a rubber boot 120 is fixedly fitted on a case outer cylindrical component 41 of a cable case 39, and the lower side portion of the rubber boot 120 is fixed to a dashboard 100 of a vehicle body 14 over the entire circumference thereof. Thus, the case outer cylindrical component 41 can be secured against rotation more firmly compared with a prior art steering device wherein such a case outer cylindrical component is fixed at two portions thereon by means of a wire of a V-letter shape. Further, the problem attendant on the wire of the V-letter shape in the prior art steering device no longer arises even in the car models wherein the case outer cylindrical component 41 and the dashboard 100 are relatively far from each other. That is, it can be realized to secure the case outer cylindrical component 41 of the cable case 39 against rotation relative to the vehicle body 14 even in any car model.

A capacitive dynamic quantity sensor whose size is small and whose reliability and mass productivity are high is provided. In order to realize signal transmission from a lower electrode to an upper electrode, silicon columns which are electrically isolated from one another but not mechanically isolated from one another are formed to connect both electrodes.

An optical switch has at least first, second, and third optical fibers disposed generally parallel to each other and spaced at non-equal intervals in a direction substantially perpendicular to an optical axis of each of the optical fibers. The optical fibers have tip portions disposed approximately along a straight line extending in a direction substantially perpendicular to the optical axis of each of the optical fibers. A first non-movable guiding structure guides a beam of light emitted from the first optical fiber to the second optical fiber along a first optical path disposed between the tip portion of the first optical fiber and the tip portion of the second optical fiber. A second movable guiding structure guides the beam emitted from the first optical fiber to the third optical fiber along a second optical path disposed between the tip portion of the first optical fiber and the tip portion of the third optical fiber so that a length of the second optical path is substantially equal to a length of the first optical path.

An image forming apparatus includes: a feeding section for feeding sheets with tabs and sheets without tabs; a tab detecting section for detecting the end position, in the sheet conveyance direction, of tabs on the sheets fed by the feeding section; a conveying section for conveying sheets that are sequentially fed by the feeding section; and a control section for controlling the conveying section in such as way as to keep constant an interval between a trailing edge of a preceding sheet in the sheet conveyance direction and a leading edge of a succeeding sheet, based on the results of tab detection by the tab detecting section.

In a recording apparatus for reproducing information recorded on a recording medium by utilizing near-field light, the recording apparatus realizes reliable information reproduction with a simple structure. Illumination light 20 is illuminated to the recording medium 10 to create near-field light on a surface of the recording medium 10. The created near-field light is scattered by a microscopic aperture 12 formed in the aperture element 11 so that scattering light (propagation light) thereof is detected to create a reproduced signal. Derived from the created reproduced light a distance control signal representative of a distance between the microscopic aperture 12 and the recording medium 10. Based on the distance control signal, the aperture element 11 is controlled in position. Due to this, the microscopic aperture 12 is brought into proximity to the recording medium 10.
摘要:
The present invention relates to a transparent conductive layered structure which comprises a transparent substrate, a transparent conductive layer and a transparent coating layer formed successively in this order on the substrate, and is used in, for instance, the front panel of displays such as CRT, etc. The transparent conductive layered structure according to the invention is characterized in that the main components of the above-mentioned transparent conductive layer are gold microparticles or gold-containing noble metal microparticles containing 5 wt % or more of gold with a mean particle diameter of 1 to 100 nm, and a binder matrix comprising at least one functional group selected from mercapto groups (—SH), sulfide groups (—S), and polysulfide groups (—Sx, X≧2). Film strength and weather resistance of the transparent conductive layer are improved because the noble metal microparticles and a binder matrix are firmly bonded via the above-mentioned functional groups.

A recording medium for recording and reproducing information utilizing near field light has a transparent substrate and a data mark arrangement layer disposed over a surface of the transparent substrate. A metal particulate is dispersed only in the data mark arrangement layer so that a surface plasma is generated upon interaction of the data mark arrangement layer with near field light generated by incident light or irradiating light to thereby amplify the intensity of scattered light generated as a result of the interaction between the data mark arrangement layer and the near field light.

A near-field optical head comprises a slider body and a cantilever arm extending from the slider body and having a contact pad at an end portion thereof for contacting a surface of a recording medium. The slider body has an air bearing surface which interacts with a film of air moving in a direction adjacent to the surface of the record medium to generate a lift force to fly the slider body over the surface of the record medium and urge the contact pad of the cantilever arm into contact with the surface of the record medium.
