Abstract:
An electronic device includes: a base; a conductor pattern formed on the base; a circuit chip electrically connected to the conductor pattern; and a reinforcing member which is disposed on the base to surround the circuit chip, whose outer shape is like a ring, and which has such an internal structure that a plurality of columns extending in the thickness direction of the base are dispersed in a predetermined substrate. The electronic device further includes a sealing member which fills an inside of the reinforcing member while covering the top of the circuit chip, thereby sealing the circuit chip on the base.
Abstract:
An object of the present invention is to provide a scanning electron microscope including decelerating-electric-field forming means for decreasing the energy of a beam of electrons reaching a sample, and being capable of selectively detecting BSEs with high efficiency. To this end, the scanning electron microscope including the decelerating-electric-field forming means has a detector for detecting electrons. The detector includes a part for receiving the electrons at a position which is positioned outside trajectories of SEs accelerated by the decelerating-electric-field forming means, and which is further away from the optical axis of the beam of electrons than the trajectories of the SEs.

A production method of an electronic apparatus includes: a step of making a thermosetting adhesive adhere to a face of a base where an antenna pattern is formed on a film made of a resin material, the face being a face which the antenna pattern is formed on; a step of mounting a circuit chip connected to the antenna pattern, on the base through the thermosetting adhesive; a preheating step of heating the thermosetting adhesive on a first heating condition by which the thermosetting adhesive becomes a first cured state; and a main heating step of fixing the circuit chip to the antenna pattern by heating and curing the thermosetting adhesive on a second heating condition by which the thermosetting adhesive becomes a second cured state harder than the first cured state, with the base being clamped and pressurized from both of the circuit chip side and the film side.
Abstract:
An optical system for an optical disc drive includes a light source, an objective lens and a collimator lens. The light source emits first and second light beams. The first light beam is for reproducing data from a digital versatile disc while the second light beam is for a compact disc. The objective lens is provided with a diffraction structure which is designed to focus the first light beam on a recording layer of the digital versatile disc and the second light beam on a recording layer of the compact disc. The collimator lens is disposed between the light source and the objective lens. The collimator lens adjusts the diverging/converging angle of the first and second light beams entering the objective lens. The change in spherical aberration of the first light beam caused by wavelength deviation from a design wavelength due to individual specificity of the light source is corrected by adjusting the diverging/converging angle of the first light beam emerging from the collimator lens.

When bonding a workpiece to a substrate, processed parts of the substrate and the workpiece are observed and behavior such as the production of voids and the flowing of resin is observed. An apparatus for observing an assembled state of components includes: a stage on which a substrate is set; a head mechanism that bonds, by applying heat and pressure, an observation workpiece made of a transparent material to the substrate via resin supplied between the substrate and the observation workpiece; a light source that irradiates an observed part of the substrate and the observation workpiece mounted on the stage with light; and a camera that takes, from the observation workpiece side, an image of the observed part when the observation workpiece is bonded to the substrate set on the stage.

An objective lens on which a beam having parallel light fluxes is incident includes a single element lens and a reflection suppressing coating formed on at least one surface of the single element lens. The reflection suppressing coating is formed such that the reflectivity across a radius of the objective lens exhibits a local maximal value, and the reflection suppressing coating is formed to achieve the following condition: 0.6
Abstract:
A scanning lens for an imaging optical system converges a beam emitted by a light source and deflected by a deflector on a target surface to form a beam spot scanning in a main scanning direction thereon. The scanning lens includes a plastic lens formed by injection molding, which has a diffractive lens structure on at least one surface thereof. The diffractive Wens structure has a plurality of annular zones arranged concentrically about a rotational axis. Each annular zone has a diffracting surface that diffracts the light beam passing therethrough. The diffractive lens structure has stepped surfaces each connecting adjoining diffracting surfaces In a plane including the rotational axis and parallel with the main scanning direction, the stepped surfaces are inclined with respect to the rotational axis so that stress working between a metallic molding for the plastic lens and each of the stepped surfaces in demolding is reduced.

There is provided an objective lens for an optical pick-up used for different types of optical discs. The objective lens has at least one surface on which a plurality of annular zones are formed. The at least one surface is divided into an inner area having a low NA and an outer area having high NA outside the inner area. Further, with regard to a light beam used for a second optical disc (e.g., a DVD), an optical path difference generated between at least one of steps formed between adjacent annular zones of the plurality of annular zones within the outer area is lower by a predetermined amount than an integral multiple of a wavelength of the light beam used for the second optical disc.

An scanning optical system includes a light source having a plurality of light emitting points each of which emits a beam, a first optical system that collimates the beams emitted by the light emitting points in regard to a main scanning direction while converging the beams in an auxiliary scanning direction, a deflecting system that dynamically deflects the beams simultaneously in the main scanning direction, and a second optical system that converges the deflected beams on the scan target surface. Further, the second optical system includes a magnification adjustment element whose magnification mS in the main scanning direction on an optical axis thereof is approximately +1 and whose magnification mP in the auxiliary scanning direction on the optical axis thereof is approximately −1.
