Title: Screen for projection type display
Inventor: KANEKO MASAHARU
IPC: G03B21/60
Filed: 1990-03-20
Abstract: PURPOSE:To improve brightness and to allow the utilization of the above screen for a stereoscopic display as well by constituting the screen in such a manner that the max. value theta of the angle of inclination of the ruggedness of a metallic reflecting layer satisfies a specific value with the refractive index (n) of transparent layer. CONSTITUTION:A transparent layer 1 may be in the form of a sheet, film, thin film or coated film and the layer having a high hardness and high resistance to gas permeability is more preferable in order to enhance the durability of the screen. Metallic surfaces in the form of a sheet, film or thin film consisting of metals, such as silver and aluminum, are usable as the metallic reflecting layer 2. The screen is so constituted that the max. value theta of the angle of inclination of the ruggedness of the metallic reflecting layer satisfies the following equation:theta<=[arc sin(1/n)]/2 with respect to the refractive index n of the transparent layer 1. The metallic reflecting layer 2 having the fine ruggedness, such as ruggedness cylindrical in a perpendicular direction, is sued as a reflecting surface, by which the internal total reflection by the transparent layer 1 on the front surface of the metallic reflecting layer is suppressed. The stereoscopic display of the improved brightness is possible in this way.

Title: Measuring instrument for orientation position of fluorescent tube
Inventor: MIYAHARA DAIKI
IPC: G01J1/00
Filed: 1989-03-20
Abstract: PURPOSE:To measure the orientation position in a short time by composing the measuring instrument of a couple of sensors which are arranged on the outer peripheral surface of a fluorescent tube 180 deg. opposite each other and generate currents corresponding to the brightness of the fluorescent tube, conversion parts, and a detection part. CONSTITUTION:The fluorescent tube 20 differs in orientation with the coating irregularity of an optical agent at its peripheral surface position. The sensors S1 and S2 are arranged on the outer peripheral surface of the fluorescent tube 20 direct opposite to each other and generate the currents corresponding to the brightness. The detection part 22 calculates the difference between the outputs of the conversion parts 211 and 212 obtained when the fluorescent tube 20 is rotated and detects the position where the difference becomes maximum. The fluorescent tube 20 has such brightness characteristics that the maximum brightness difference is obtained at an about direct opposite position without fail, and this relation is unchanged even in a period wherein brightness variation in 5 - 10 minutes right after the start of illumination is large. Consequently, the position where the output of the detection part 22 becomes the positive (or negative) maximum value is a position to be found, it is not necessary to wait for the brightness to become stable, and the orientation position can be measured even in the period wherein the brightness variation is large.

Abstract: PURPOSE:To enable the determination of the alignment of bases of DNA in a short time with high reliability, by detecting radiations emitted from a plurality of DNA samples which migrate parallel in the vertical direction on a migration plate, and by converting same into the alignment of four kinds of bases of DNA. CONSTITUTION:Radiations emitted by DNA samples (a) ionize a filler gas such as argon, and make electrons radiate therefrom. These electrons are gathered on an anode wire 4, and a pulse of a current is thereby generated at a position (b) thereon. This pulse is propagated to a position (c) on a delay line and taken outside as signals 12 and 13. The signal 12 taken out is shaped and inputted to a start input terminal 17 of TAC 16, while the signal 13 is shaped and inputted to a stop input terminal 21 of TAC16 after a prescribed time T passes. An output 24 from TAC16 is passed through MCA22, and informations on all channels of MCA22 are transferred to a microcomputer C and then stored in an outside memory 23. When the informations are determined as sufficient for deciding the kinds of bases, the kinds of the bases are decided on the basis of these informations and are stored in a prescribed area of the outside memory.
