IPC: C12Q1/00
Filed: 1989-07-05
Abstract: PURPOSE:To obtain a flow type luminous sensor having a uniformly immobilized enzyme capable of readily measuring various kinds of organism substances without changing a light transmission hollow tube by inserting an enzyme immobilized to the surface of polymer base by covalent bond to the light transmittance hollow tube. CONSTITUTION:The above-mentioned luminous sensor wherein a polymer yarn 1 having an enzyme immobilized thereto is inserted into a light transmittance hollow tube 2 set in a spiral way to a light receiving face of a multiplier phototube 5. Consequently, in changing an aqueous solution 3 of test specimen to be measured containing a measuring target substance, namely organism substance and a luminous substance, the measuring target substance can be changed only by replacing yarn 1 having the luminous enzyme 4 immobilized thereto in the hollow tube 2. Since the enzyme is immobilized to the surface of the yarn 1 different from existing method wherein the enzyme 4 is immobilized to the inner face of the hollow tube 2, the luminous sensor is formed by ready immobilization operation of the enzyme 4 and the enzyme 4 can be uniformly immobilized. 6 in the figure shows luminescence.

Title: Low carrier frequency modulation circuit for color video signal
Inventor: SAKAKURA KENICHI
IPC: H04N9/64
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a low carrier frequency modulation circuit for a color video signal in which a monitored video image is not subjected to a color change by separating a horizontal synchronizing signal from a color video signal of a video signal source, oscillating a signal synchronously with the separated horizontal synchronizing signal so as to frequency-modulate the color video signal, thereby decreasing a change in an amplitude and a phase of a demodulated color difference. SOLUTION: A synchronizing separator circuit B1 receiving a color section LN1 from a video signal source SG1 separates a horizontal synchronizing signal LN2 from the signal LN1, a differentiation circuit B2 differentiates the separated horizontal synchronizing signal LN2, and a comparator B3 receiving a differentiated horizontal synchronizing signal LN3 outputs an impulse signal LN4. The width of the impulse signal LN4 is narrow and the color video signal LN1 is frequency-modulated at a voltage frequency conversion circuit VCO1 synchronously with the impulse signal LN4. Thus, the phase and the amplitude of each color video signal LN1 take a same timing for each horizontal scanning period so as to avoid a color change of the monitored video image from being caused.
