Abstract: PURPOSE:To provide a stable video image with less cross luminance and cross color by subtracting an output of a median selection circuit from the output of a band limit filter so as to generate a color signal and making a luminance signal through the subtraction of the color signal from the video signal. CONSTITUTION:Only a chrominance subcarrier wave and its vicinity is extracted from a video signal at a band limit filter. Then the extracted signal and a signal delaying the extracted signal by 1H at a 1H delay circuit 7 are added at an adder 8, and the sum signal is given to a median selection circuit 10, by which a change in a color signal in the vertical direction is detected.

Filed: 1992-07-03
Abstract: PURPOSE:To obtain a picture with high picture quality excellent in reproducibility of a picture regardless of fluctuation in the subscanning speed by detecting a fluctuation quantity of a subscanning speed during scanning of an original and setting the content of read position correction in response to the fluctuation quantity. CONSTITUTION:A CPU 101 uses an internal timer to count a pulse period of an output pulse signal F/G during original scanning to detect a scanning speed. Then based on a regular speed and a measured value in response to a read magnification, a position deviation of reading due to a scanning speed unevenness is calculated by a prescribed arithmetic operation. Then the CPU decides the number of delay lines and a weight coefficient based on a position deviation due to the read magnification and the position deviation due to the scanning speed unevenness. Then the CPU 101 uses the number of delay lines as delay data DL and uses the weight coefficient as interpolation ratio data DH and gives them to a position correction section 130. Thus, a picture with high picture quality is obtained regardless of the fluctuation of the subscanning speed.

IPC: G01N33/53
Filed: 1980-12-15
Abstract: PURPOSE:To detect anti-ACR antibody by a cohesive reaction of sensitizing latex reagent sensitized by contacting ACR with latex particles in an aqueous medium of a physiological salt solution. CONSTITUTION:About 0.1-1mu average particle size latex of a uniform polymer of chlorostyrene, vinyl chloride, vinylidene chloride or a copolymer of said monomer, is treated by a nonionic surface active agent and is sensitized by contacting with ACR obtained from a femoral muscle of a mammal or an electric organ of fishes in an aqueous medium of a phisiological salt solution or various buffer salt solutions. On this occasion, it is preferable to carry out the sensitization at 6.0-9.0 pH and a temperature of 4-40 deg.C. Unpeculiar cohesion is prevented by saturating the remaining face by particles having a property of adsorbing by the latex particles such as cattle blood serum albumin after sensitizing treatment. Thus obtained latex reagent can be preserved for a long period by freeze-drying and also, can be used as a fresh product in the same way only dissolving by a diluent at the time of use.

Abstract: PURPOSE:To thin an active layer, holding the thickness of a P-type clad layer, and to increase an output by forming a groove at the center of a ridge in two- stage structure. CONSTITUTION:A P-type Al0.4Ga0.6As clad layer 3, an Al0.08Ga0.92As active layer 4, an N-type Al0.4Ga0.6As clad layer 5 and an N-type GaAs contact layer 6 are grown on a P-type GaAs substrate 1, a mesa 1a, an N-type GaAs current constriction layer 2 and ridges 2a, 2b in succession through a liquid growth method, and an N side electrode 7 and a P side electrode 8 are shaped through evaporation. Growth on the ridges 2a, 2b is inhitited as compared to the side surfaces of the ridges 2a, 2b by the anisotropy of crystal growth, and the P-type clad layer 3 is grown flatly extending over width W on the ridges 2a, 2b. Width W is narrowed when ridge width is narrowed at that time, but the thickness (t) of the P-type clad layer 3 on a flat section at the first stage of a groove 9 is hardly altered though width W is narrowed. When width W is brought to 80mum or less, an output can be increased by an effect in which the groove is formed at two stages.

Abstract: PURPOSE:To form the pit of good quality by irradiating a magneto-optical recording medium with laser light whose power is equal to or exceeding normal recording light power while the bias impressed magnetic field is not saturated at a recording stage. CONSTITUTION:Until the magnetic field which is sufficient enough to reverse the magnetized direction of the magneto-optical recording medium 2 is impressed on the magneto-optical recording medium 2, the laser light is driven with the power stronger than the laser light with which the magneto-optical recording medium 2 is irradiated when the magnetic field is fully impressed corresponding to an information signal irradiating the magneto-optical recording medium 2. Ordinarily, a semiconductor laser 5 is turned on with the fixed light power, but the laser 5 is turned on with the power equal to or exceeding the fixed power value until a signal reversal detecting signal S1 is inputted in a light modulation circuit 15 and a magnetic field saturation detecting signal S2 is inputted. Thus, the pit of good quality can be formed, so that the unstable area of the magnetic field is generated as little as possible and also good overwriting can be performed.
