    摘要: A projection optical unit for a projection display apparatus, which displays an image upon a projection surface, obliquely, includes a front lens group disposed in a direction from an image display element to a projection surface, a rear lens group, and a reflection mirror formed so that a curvature of a portion for reflecting a light beam incident upon a lower end portion of the projection surface is larger than a curvature of a portion for reflecting a light beam incident upon an upper end of the projection surface. An optical axis of the front lens group and the rear lens group is more inclined with respect to a direction of the portion of the reflection mirror for reflecting the light beam incident upon the lower end portion of the projection surface than a normal line direction of the image display element.

    摘要: An object of the invention is to carry out the flux method with improved work efficiency while maintaining the purity of flux at high level and saving flux material cost. The sodium-purifying apparatus includes a sodium-holding-and-management apparatus for maintaining purified sodium (Na) in a liquid state. Liquid sodium is supplied into a sodium-holding-and-management apparatus through a liquid-sodium supply piping maintained at 100° C. to 200° C. The sodium-holding-and-management apparatus further has an argon-gas-purifying apparatus for controlling the condition of argon (Ar) gas that fills the internal space thereof. Thus, by opening and closing a faucet at desired timing, purified liquid sodium (Na) supplied from the sodium-purifying apparatus can be introduced into a crucible as appropriate via the liquid-sodium supply piping, the sodium-holding-and-management apparatus, and the piping.

    摘要: A projection display is capable of suppressing both the trapezoidal distortion of an enlarged image projected on a screen by oblique projection and aberrations resulting from oblique projection and includes a projection optical system provided with lenses that can be easily manufactured and assembled. The projection optical system for obliquely projecting an image formed by a display device on the screen includes a free curved lens having a rotationally asymmetric free curved surface. The free curved lens has fringing parts having outlines of a shape coinciding with an arc of a circle having the center on the optical axis of the free curved lens.

    摘要: In a method for driving a micro mirror such as MEMS mirror and a display apparatus using the method, there are provided a mirror driving unit for driving the micro mirror which operates in a resonant mode and a nonresonant mode, a driving-condition setting unit for setting a mirror driving condition, a switching unit for switching on/off a mirror driving signal in the nonresonant mode, and a look-up table for indicating the relationship of a mirror response with respect to the driving condition already known in advance. The switching unit controls the transmission of the nonresonant-mode mirror driving signal while grasping the mirror response state with respect to the mirror driving signal, thereby finely increasing and decreasing a driving torque for the micro mirror. This fine increase and decrease allows the micro mirror to be fluctuated stably, and a further enhancement in the fluctuation rate.

    摘要: A light emitting element having a light emitting element portion formed of a group III nitride-based compound semiconductor and having a layer to emit light. The light emitting element portion is formed by lifting off a substrate by wet etching after the light emitting element portion is grown on the substrate. The light emitting element portion has a lift-off surface that is kept substantially intact as it is formed in growing the light emitting element portion on the substrate.
