Title: Chrominance signal processor
Inventor: YAMAMOTO NAOKI
IPC: H04N9/84
Filed: 1987-02-16
Abstract: PURPOSE:To obtain a device which is suitable to be integrated and can be made with a low cost by sharing a CCD delay circuit with an 1H delay circuit which eliminates the interruption for a pilot signal caused by a flyback pulse. CONSTITUTION:A regenerating signal is supplied to a first balanced modulator (BM) 5 and the 1H delay circuit 4 through a low path filter (LPF) 2 and an automatic chroma level control circuit (ACC) 3 and delayed 1H by the 1H delay circuit 4. Then the delayed signal is supplied to a second BM 6. The output of a VCO 13 is frequency-divided by an 1/2 frequency dividing circuit 15 and an 1/4 frequency dividing circuit 16 and supplied to a phase invert PI circuit 24 as the signal C1 of frequency fS and the signal C2, C3 and C4 of which phases are respectively delayed 90 deg., 180 deg. and 270 deg. less than that of the signal C1. On the other hand, and a regenerated pilot signal can be obtained by subtracting the output of the 1H delay circuit 4 from the output of the ACC 3 with the aid of a subtracting device 26, eliminating the interruption caused by the flyback pulse and passing it through a BPF 27. Thus as the CCD delaying circuit can be shared with the 1H delay circuit which eliminates the interruption for the pilot signal caused by the flyback pulse, the device which is suitable to be integrated and can be made with the low cost is obtained.

Abstract: PURPOSE:To obtain a flow sensor achieved in miniaturization and the enhancement of capacity and having a shape suitable for mass production, by using a thin plate low in heat conductivity as a substrate and respectively arranging a heat generating resistor and a temp. measuring resistor to both end positions thereof in a thermally insulated state. CONSTITUTION:A pair of a temp. measuring resistor 3 and a heat generating resistor 2 are arranged in a flow passage 7 and respectively connected to other electric resistor elements 6, 6' to constitute a bridge. Then, a transistor 9 is turned ON to supply the current supplied from the input terminal 10 connected to a source terminal to the resistor 2 to allow said resistor 2 to generate heat. When the speed of a fluid is high, a large quantity of heat is taken from the resistor 2 by the fluid. Contrarily, when the flow speed is low, the quantity of heat taken from the resistor 2 is reduced. The temp. of the fluid is measured by the resistor 3 and the supply quantity of a current to the resistor 2 is controlled so as to make the temp. difference between the fluid and the resistor 2 constant. In order to keep the temp. difference constant, the value of a current made to flow to the resistor 2 is controlled on the basis of the temp. detection signal of the resistor 3. The current value required at this time comes to the flow speed of the fluid.
