摘要： In a projection type image display apparatus, for enlarging an image on a image display apparatus 1 by means of a projection lens 2, thereby projecting the enlarged image onto a screen 6, obliquely, being inclined thereto, between the projection lens 2 and a rear-surface mirror 5, there are disposed free shaped surface mirrors 3 and 4, each having a free shaped surface for compensating a trapezoidal distortion due to oblique projection of the enlarged image. The surface configuration of the free shaped surface mirror is so shaped as to satisfy a following equation: |L1−L2|>1.4·Dv if assuming that a distance for a light beam of an upper end of the enlarged image to reach the screen after being reflected upon a free shaped surface is “L1”, a distance for a light beam of a lower end of the enlarged image to reach the screen after being reflected upon the free shaped surface is “L2”, and a distance from an upper end of an image on the screen to a lower end thereof is “Dv”.

摘要： For enabling to prevent ill effects from being generated in the structures of a reflection mirror, even if increasing an output energy from a light source, thereby preventing ill influences from being exerted on the driving condition thereof, a mirror drive controller unit 7 reads out history data of the past, relating to temperature changes on a micro mirror 1, from a first LUT holder unit 19. Upon basis of the read-out history data of the past is presumed the temperature on the micro mirror 1 at the present time. The presumed temperature on the micro mirror 1 is temperature P temp of the micro mirror 1 at the present time, and upon that P temp are changed vibration (or oscillation) condition of the micro mirror 1 in the horizontal (H) direction and vibration (or oscillation) condition thereof in the vertical (V) direction.

摘要： An apparatus for manufacturing a Group III nitride semiconductor is composed of a pressure vessel, a reaction vessel disposed within the pressure vessel, a heating device disposed within the pressure vessel so as to heat the reaction vessel, and a glove box filled with argon gas. The pressure vessel and the glove box are connected to each other via a gate valve. By virtue of this configuration, a large-sized reusable reaction vessel can be disposed within the pressure vessel without causing oxidation of Na.

摘要： A Group III nitride semiconductor crystal is grown according to a flux method. After completion of the crystal-growing process, Na is discharged from a crucible by a recovery device when the temperature of the crucible is 100° C. or higher, and is held in a holding vessel in a liquid state. The recovered Na can be drawn from the holding vessel via a faucet. Na remaining after completion of the crystal-growing process does not contain impurities of high vapor pressure, and is thus of high purity. Therefore, reuse, as flux, of the recovered Na enables manufacture of a Group III nitride semiconductor whose concentration of impurities is low.
