Title: Optical pulse noise reducing device and noise-reduced light receiver using the device
Inventor: MUKAI TAKAAKI
IPC: H04B10/60
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To output an optical pulse of which noise by the number of light quanta is reduced as compared with an input optical pulse by utilizing an effect that noise components in an optical pulse are redistributed on an wavelength axis. SOLUTION: When a large number of light quanta per pulse is compared with a small number as to fluctuation in the number of light quanta, a fluctuation component increasing the number of light quanta can selectively and efficiently wavelength-convert the fluctuation of a spectrum center part into a spectrum peripheral part in a four-light wave mixing process by a tertiary light non-linear effect and reduce the amplitude fluctuation of the center part as compared with a fluctuation component reducing the number of light quanta. On the other hand, the fluctuation of the center part is stored in the peripheral part and noises are increased.  Thereby a shot noise of an input optical pulse is redistributed into the center part with a small noise and the peripheral part with much noise accumulation on the wavelength axis at the output end of an optical non-linear medium 1 with tertiary non-linearity. A means 2 constituted of a wavelength selecting element can remove a wavelength component having low spectrum strength in the peripheral part having a big noise from the input optical pulse and extract a noise-reduced output optical pulse having large spectrum instensity in the center part with a small noise.

Title: Liquid crystal display device and its manufacture
Inventor: HOSHI JUNICHI
IPC: G02F1/1335
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a device having good characteristic of black display, high contrast, at low cost and showing stable performance by comprising one substrate having a part of angled shape and making the angled shape a polygonal cone or circular cone. SOLUTION: An angle-shaped pattern is formed on a whole surface of a resin thin film 3 formed on a glass substrate 1 by a replica method. The highest part 5 of the angle is equivalent to the vertex of a quadratic cone, the lowest part of a bottom is equivalent to the base of the quadratic cone and four slopes exist for a quadratic cone. An ITO thin film 7 is evaporated on the upper surface of the thin film 3. Since a reflected light beam is reflected in four directions, the intensity of the reflected light becoming a noise per unit solid angle is lowered. Since no difference of beams between the vertical direction and the lateral direction exists, the image performance of a liquid crystal cell and reflection type LCD have no difference between the vertical-and lateral directions.  When the vertex of the angle is somewhat rounded and the beam is reflected to the front face of a schlieren optical system, since the area of the vertex is minimum, the deterioration of black display is minimized.
