Title: Chrominance signal base clip circuit
Inventor: NIKAWA HIDEMITSU
IPC: H04N9/68
Filed: 1993-05-12
Abstract: PURPOSE:To prevent a false color generated due to the change of a color phase in a clip area in a base clip circuit for a chrominance signal. CONSTITUTION:Color saturation information EC is read from a ROM 1 using the input chrominance signal as an address. A constant T1 is subtracted from the EC by a subtractor 21, and when the subtracted output EC1 is negative. 0 is forcedly outputted from gates 23-25, and when the EC1 is positive, the EC1 is outputted as an EC3 as it is (0 clamp output). The EC3 is multiplied by a multiplier G by a multiplier 26, and an EC4 is obtained. When the EC4 is beyond a constant T2, the T2 is outputted, and when the EC4 is less than the constant T2, the EC 4 is outputted as an EC5 as it is (T2 clamp output). The EC5 is multiplied by the chrominance signal by multipliers 3 and 4, the gain is controlled by gain adjusters 5 and 6, and a base clip output is obtained. Then, the level adjustment of the input chrominance signal is simultaneously operated by the color saturation being the brightness of a color of the input chrominance signal, so that color slippage can be prevented.

Title: Optical fiber rotational angular velocity meter
Inventor: NAKAMURA SHIGERU
IPC: G01C19/00
Filed: 1987-06-01
Abstract: PURPOSE:To obtain a velocity meter which reduces a drift due to temperature variation by winding an FSL(fiber sensing loop) around a bobbin so that both end parts of a two-core optical fiber tape core are at the same position, and connecting mutually different two-core optical fibers at both end parts, core by core. CONSTITUTION:The connection part of optical fibers 3 and 4 at both end parts 21 and 22 of the optical fiber tape core conductor 2 is in the lengthwise center of the optical fiber of the FSL, and the fibers 3 and 4 at an equal distance from the center pass invariably equal positions of the bobbin 1. Then the fibers 3 and 4 never cross each other on the surface of the bobbin 1. Light from a light source is therefore branched by an optical system for branching and coupling and then propagated in the FSL in the mutually opposite directions, and they are coupled mutually by the optical system for branching and coupling and incident on a photodetector. At this time, when the FSL rotates, the propagated light beams which travels in the FSL in the mutually opposite directions have a phase difference, from which the angular velocity of the FSL is found.

Abstract: PURPOSE: Thin ferrite film is coated with a metal having an ionization tendency smaller than that of iron, and heat treated in a alcohol atomosphere. The process produces ferrite spherulite useful as polarizer, analyzer and magnetic recording medium.  
     CONSTITUTION: A thin layer of ferrite such as hematite or magnetite is deposited with a metal, as a reducing agent, such as Cu or Ag of which an ionization tendency is smaller than that of Fe, or a compound thereof. Th metal-deposited layer is  heat treated in an atomosphere of alcohol such as CH 3 OH, C 2 H 5 OH and (CH 3 ) 2 CHOH to the effect such that the near zone of the metal or its compound is reduced more easily to cause oxygen deficiency there. The oxygen difficiency spots serve as nucleus and cause magnetic spherulite to grow. The spherulite size can be desirably controlled by deposited metal size, period of heat treatment and others. The spherulite 3 in accordance with the invention consists of microfiber 5 of hematite grain extending radially from the center nucleus 2 and changes a incident ray A to a polarized light B as illustrated.
