Title: Collimation method by simple autocollimator and simple collimator using same collimation method
Inventor: IIZUKA TADASHI
IPC: G01B11/26
Filed: 1986-11-12
Abstract: PURPOSE:To perform high-precision collimation by a simple device by providing a small point to an objective and realizing the same operation with a target. CONSTITUTION:A virtual image 8 of the point (mark) 2 of the objective 1 projected on a plane reflecting mirror 7 fitted to a body 6 to be measured is collimated from the ocular 4 of a telephotoscope optical system and formed in the center 9 of the cross line of a focus plate 5. In this case, when the distance from the point 2 to the reflection mirror 7 is denoted as S, the distance to a focus surface 9 is denoted as (b), and the focal length of the objective system is F, the distance of the virtual image 8 is 2S, and 1/2S+1/b=1/F holds. When the reflecting mirror 7 slants by alpha, the virtual image shifts in position by 2alphaS to a position 10. The position shift 11 of the image formation surface of the telephotoscope system is 2alphaFS/(2S-F), so the image formation surface is returned to its original position by eliminating the inclination alpha of the reflection mirror 7. When the focal length F is 270mm, the distance S is 500mm, and the quantity of the shift on the focus plate 5 is 0.01mm, the precision is about 5.4' and sufficient angle precision is obtained.

Title: Magneto-optical recording medium for positioning of exposure device
Inventor: SASAMORI EIZO
IPC: G11B11/10
Filed: 1988-10-26
Abstract: PURPOSE:To secure a satisfactory reading contrast of a mark image by forming a lamination of a 1st magnetic layer having a high Curie temperature and a low coercive force and a 2nd magnetic layer having a relatively low Curie temperature and a high coercive force. CONSTITUTION:The magneto-optical recording mediums 6 and 30 of an exposure device containing a positioning optical system 9 set distant from the optical axis of a projecting optical system 3 and a recording medium 4 set on a mobile stage 5 are formed with lamination of a 1st magnetic layer 23 having a high Curie temperature and a low coercive force and a 2nd magnetic layer 22 having a relatively low Curie temperature and a high coercive force. At the time of exposing a magnetic field larger than the coercive force of the layer 23 is applied in the direction where the magnetization of the layer 23 is inverted together by irradiating it with the mark light via the system 3. Thus the temperature of the layer 22 exceeds the Curie point and the magnetization of the layer 23 is inverted. When the irradiation of the mark light is cut off, the temperature of the layer 22 falls and the magnetization of the layer 22 is inverted in the stable direction to the layer 23 in response to the magnetization of the layer 23. Then a mark image is recorded. Thus a satisfactory reading contrast is secured to the mark image and this image can be detected with high accuracy.

Title: Optical pickup device
Inventor: OKA SADAICHIROU
IPC: G11B7/135
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation of wave front aberration amount at a tracking operation time by moving an optical element changing a transmissivity distribution according to the wavelength of a light beam together with an objective lens at the tracking operation time. SOLUTION: In this optical pickup device, the effective numerical aperture (substantial numerical aperture to the light beam incident on the objective lens 6) of the objective lens 8 is changed according as the wavelength of the light beam is 650nm, or 780nm. This effective numerical aperture is set so as to become large when the wavelength of the light beam is 650nm, and to become small when the wavelength of the light beam is 780nm. Thus, when a high density recording medium is reproduced, a small spot is formed on a recording surface, and when a low density recording medium is reproduced, a relatively large spot is formed on the recording surface.

Title: Camera
Inventor: ASANO SEIJI
IPC: G03B19/07
Filed: 1989-10-16
Abstract: PURPOSE:To execute the compensation of parallax accompanied with the switching of photographing magnification with simple constitution by switching and positioning one of lenses on a photographing optical axis and displaying a reference for the compensation of parallax in a finder corresponding to the switching and positioning the lens. CONSTITUTION:When the rotation of a lens holder is continued, the energizing force of a toggle spring 67 acts in a direction where the counterclockwide rotation is promoted from the middle of the rotation and the rotation is stopped in a state where a sector 65 abuts on a stopper 58. At such a time, a macro lens 14 is positioned on the photographing optical axis 13 and a target mark 19 is interposed in a finder 18. In such a state, the lens holder is positioned and fixed between the toggle spring 67 and the stopper 58. Since the mark 19 is observed in detail by the diffraction phenomenon of object light, the center of the object is caught in the aperture of the mark 19. Thus, the compensation of parallax is performed by taking the mark 19 as the reference.

Title: Recording device, recording and photographic sheet
Inventor: IKEMOTO YUICHIRO
IPC: B41J2/52
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent a moire stripe or the relative misalignment of a a color caused by a recording dot shear from occurring. SOLUTION: The recording position of a dot per single dot is reversed in a single pixel area on a recording device so that the alignment direction of a dot to be formed on a photographic sheet 50 is different from a main scan direction. Consequently, if the photographic sheet is misaligned in a photographic sheet feeding device and the position of the photographic sheet 50 is deviated from a thermal head 7, the incidence of a moire stripe in the main scan direction can be reduced as the dot is arranged in zigzag fashion, in the main scan direction line of the photographic sheet 50 on which a dot patter is formed from image data.

Abstract: PROBLEM TO BE SOLVED: To automatically correct the fluctuation in display density due to temperature change of a liquid crystal display panel by determining the voltage to be supplied to the liquid crystal display panel in accordance with a reference value which is a standard drive voltage and a correction value to increase or decrease the reference value in accordance with the measurement result of a temperature sensor. SOLUTION: An average value A is obtained from the values measured 100 times (S1). When the average value A is higher than a present value B (S2), 1 is added to the present value B (S3). When the average value A is equal to the present value B, the present value B is not changed (S4). When the average value A is lower than the present value B, the 1 is subtracted from the present value B (S5). The correction value B' is obtained from the present value B (S6). The correction value B' is calculated by substituting the present value B in a prescribed calculation equation. The fresh voltage value C to drive an LED is determined (S7). The voltage value C is the value obtained by adding the reference value O, the correction value B' and a user set value U and drives the LED with the freshly set drive voltage.
