Title: Optical disk head
Inventor: MATSUDA KAORU
IPC: G11B11/105
Filed: 1985-07-11
Abstract: PURPOSE:To perform erasing and writing with low noise by dividing an emitting ray of light from a semiconductor laser into two beams by a polarization separating plate and setting the first beam for the erasing and the second beam for the writing. CONSTITUTION:Linear polarized light emitted from a semiconductor laser 1 is arranged to a parallel beam by a collimator lens 3 and is divided to two linear polarized rays of light 12a and 12b which intersect orthogonally at a polarization separating plate 11. Out of these, one of them, the linear polarized beam 12a is used for the erasing and the other, the linear polarized beam 12b for the writing. The linear polarized beam 12b, after passing a polarizer 13 and a magneto-optical crystal 14, is arrived at a polarization beam splitter 2 and changes outside magnetic field impressed on the magneto-optical crystal 14 by an electromagnet. A device is constituted so that the polarizer 13 is arranged to face with the transmission of the linear polarized beam 12 and the magneto-optical crystal 14 has the thickness to rotate the polarization surface of the linear polarized ray of light 12b by 45 deg. when the outside magnetic field is impressed by saturation magnetic field H in the advancing direction of light.

Title: Color liquid crystal display panel
Inventor: YAMAGUCHI TOSHIHIRO
IPC: G02F1/1335
Filed: 1990-06-13
Abstract: PURPOSE:To obtain the product having a high contrast and high image quality and to improve productivity by using plural polarizing plates on a substrate side and disposing the polarizing plates in superposition by varying the polarization directions from each other in such a manner that the optically rotatory light of respectively different wavelength regions past a TN liquid crystal layer is shielded. CONSTITUTION:The polarization directions of the polarizing plates 1-1 to 1-3 are so set that the transmitted light is kept at a minimum level with respect to the light of the respective wavelength regions of green (G), red (R) and blue (B) as the form of disposition of these polarizing plates. Since the polarizing plate 1-1 is in the orthogonal relation with the polarization direction N-1, only the green light is shut off and the red and blue light is transmitted. The red light is shut off by the next polarizing plate 1-2 and further, the blue light is shut off by the polarizing plate 1-3. Then, the rays of R, G, B are completely shut off and the leak light and the coloration of the black chromatic colors by the optical rotatory power of the liquid crystal are drastically decreased when the liquid crystal segments make black display. The high contrast and the high image quality are thus obtd.

Abstract: PURPOSE:To eliminate resonance or noise generated by an impact vibration resulting from the printing operation of a printer by filling the hollow cylinder of a metal cylindrical body of a platen with glass wool containing activated charcoal and sealing both ends tightly with a flange. CONSTITUTION:The hollow cylinder of a metal cylindrical body 3 is filled with glass wool containing activated charcoal having a vibration absorption damping effect, and becomes airtight with flanges 4, 5 installed. If a platen installed on an impact printer operates, a printing section performs printing process under pressure on the surface of the platen, and a noise of impact vibration is transmitted to the metal cylinder of the platen to cause resonance in the metal cylinder. Consequently, the resonance is damped by glass wool containing activated charcoal provided in the metal cylinder and thus noise resulting from the resonance is reduced.
