Title: Directive reflection screen and picture display device
Inventor: OSHIMA TETSUYA
IPC: G02B5/09
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To widen the horizontal viewing range of a picture display device using a laminated mirror group being suitable for a stereoscopic picture device by making laminated mirror surfaces constituting the laminated mirror group curved in a cut surface perpendicular to the ridge line of the laminated mirrors. SOLUTION: A laminated mirror group is constituted so that each mirror surface is a concave surface (a) or a convex surface (b), and forms a circular-arc having a curvature in a cross-section perpendicular to the ridge lines of the laminated mirrors. A light beam made incident on the laminated mirror group is successively reflected on two mirror surfaces and almost reflected in a direction that it is made incident on. Since the mirror surfaces are provided with the curvature differently from a conventional way, a substantial included angle β becomes different according which position of the mirror surface the light beam is made incident on. According as the substantial included angle β, the reflecting direction δof the light beam is deviated as much as |(β-90)|×2 from the incident direction.  Since the reflecting direction δ becomes different within the respective laminated mirror surfaces, the reflected light beam is spread. The spread angle of the reflected light beam becomes different according to the pitch of the laminated mirrors, the average included angle and the radius of the curvature of the mirror surface.

Abstract: PURPOSE:To make narrow the band of a wavelength by a method wherein laser medium means are installed in the interior of a resonator, which is constituted of an output mirror and a wavelength selecting optical system, and an optical path length between the output mirror and the laser medium means is made smaller than that between the wavelength selecting optical system and the laser medium means. CONSTITUTION:An output mirror (front mirror) 7 constituting a resonator is provided on the front side of a laser chamber 1 and prisms 11 and 12 of a wavelength selecting optical system 10 and a diffraction grating 13 are provided on the rear side of the chamber 1. A movable mechanism 16, which is actuated by a wavelength adjusting mechanism 15, is attached to the grating 13 and angle adjustment of the grating 13 to an optical axis is performed. Laser gas is sealed in the chamber 1 as a laser medium. By making smaller the length Lc between electrodes 2 and 3, which are an excitation means, and the front mirror 7, which is an output take-out means, than the length Lb between the electrodes 2 and 3 and the prism 11 of the system 10, the angle of a discharge space, which is subtended at a narrow-band element, becomes smaller. As a result, the width of a spectrum, which contributes to an oscillation, becomes smaller.

Title: Method for determining slit number of absolute encoder
Inventor: UEDA TOSHITSUGU
IPC: G01D5/347
Filed: 1986-06-27
Abstract: PURPOSE:To obtain the best number of slits which make an error permitted for phase detection larger when obtaining target accuracy by setting the number of slits to an integral value close to N<1/2>/2 for the target accuracy + or -1/N. CONSTITUTION:The light and dark of light corresponding to the positions of the slits 21 and 22 are converted into phase signals Va and Vb by scanning a photodiode array 4. At this time, the phase signal Va changes in phase between '0' and 2pi (n) times in every turn of a code plate 2 and the phase difference phiab between the phase signals Va and Vb changes once. For the purpose, the section of the phase signal Va is found from the phase difference phiab and the section is interpolated with the phase signal Va to find an angle theta of rotation. In this case, an error in the measurement of the phase of the signal Va needs to be <2pi/4n so as to find the section accurately and <2pin/N so as to obtain the target accuracy + or -1/N, so the best number of slits is N<1/2>/2.

Abstract: PURPOSE: To secure printing with the print picthes of the characters of different print widths by memorizing previously both the width data and the print space for each character into the memory and then giving the arthmetic process to the print pitches based on the memorized data.  
     CONSTITUTION: Both the space between the print characters and the width data of the print characters are memorized previously into ROM4, and the character width data is memorized into RAM5 between the character which received the printing command via keyboard 1 and the character printed right before the first mentioned character. Based on the data given from RAM5, the addition mean value is calculated between the width of the character commanded for printing through CPU3 and the width of the immediately preceding character. And the space between the print characters is read out of ROM4 and added to the calculated addition mean value. Based on this addition value, the pitch of print head 10 is shifted to print out the character adjacent to the immediately preceding character. Thus an automatic adjustment is possible for the print pitch even with different widths of characters to secure the printing with an easy-to-read pitch.
