Title: Chroma signal processing circuit
Inventor: OBARA NAGAYOSHI
IPC: H04N9/78
Filed: 1989-04-05
Abstract: PURPOSE:To reduce the scale of a chroma signal processing circuit and to secure the satisfactory effect of a tandem line filter by detecting the correlative and noncorrelative states with a demodulated color difference signal, and controlling the filter. CONSTITUTION:The correlative and noncorrelative states of chroma signals are detected by comparing the DC levels of demodulation outputs 14a and 15a with each other between a signal 4a received from a delay element 4 and a signal 2a received from an addition circuit 2 by a comparator 16. When the level difference between both signals 14a and 15a is smaller than the prescribed value, the correlation is confirmed between chroma signals and a switch 9 conducts by the detecting signal showing the correlative state. Thus the chroma signals are obtained with the cyclic characteristics obtained from the sharper characteristics of a normal tandem line filter. When the level difference between both signals 14a and 15a is larger than the prescribed value, the noncorrelative state is confirmed between chroma signals and the switch 9 becomes inconductive. As a result, the difference component obtained from an amplifier 8 is not circulated to the circuit 2 any more. Then the chroma signals of the normal tandem line characteristics are obtained.

Title: Compound generating plant
Inventor: NOGUCHI YOSHIKI
IPC: F01K23/10
Filed: 1987-04-08
Abstract: PURPOSE:To obtain optimum water supplying conditions by supplying feed water to a high- pressure economizer of an exhaust heat recovery boiler after a high-pressure water supply system is heated to a higher temperature than a low-pressure water supply system, using turbine extracted steam, etc., so as to meet the water supplying condition to the high-pressure system and low-pressure system. CONSTITUTION:Gas turbine exhaust gas 2, heat of which is recovered by an exhaust heat recovery boiler 4, is discharged as an exhaust gas 3. The exhaust heat recovery boiler 4 generates high-pressure steam 13 from high-pressure feed water 15, and low-pressure steam 14 from low-pressure feed water 16. Each steam is condensed into condensed water in a condenser 19 by rotating a generator 18 by means of a steam turbine 17. Then, the condensed water is extracted by a low-pressure water supply pump 20, and heated by turbine-extracted steam 25, and passes through a low-pressure feed water heater 22, a deaerator 23, passes through a high-pressure feed water heater 24 from a high-pressure water supply pump 20, and the high-pressure feed water 15 to a high-pressure economizer is obtained. The condensed water diverges from an outlet of the low-pressure water supply pump 20 at a fixed ratio, and the low-pressure feed water 16 to a low-pressure economizer 12 is obtained. Since the low-pressure feed water with lower temperature than the high-pressure feed water is supplied to the low-pressure economizer 12, the heat of the exhaust gas 3 can be recovered up to low temperatures.

Filed: 1986-04-14
Abstract: PURPOSE:To improve the contrast of an image and to reduce the humidity dependency of the quality of the image by coating ferrite particles with resin contg. a specified styrene-acrylic copolymer as the principal component. CONSTITUTION:Ferrite carrier particles represented by a formula (MO)100-x(Fe2 O3)x are coated with resin contg. a styrene-acrylic copolymer having 30-90wt% styrene content as the principal component. In the formula, M is Ba, Ni, Zn, Mg, Mn or Li and x=55-70mol%. In case of x<55mol%, the saturation magnetization is reduced to deteriorate the developing property and to cause sticking. In case of x>70mol%, the saturation magnetization is increased to make an image linearly uneven. In case of <30wt% styrene content, the developing property is not sufficient. In case of >90wt% styrene content, the coating film is hard and liable to be stripped.

Abstract: PURPOSE:To generate an output voltage within an allowable range even when Hall elements, exhibiting fluctuation when being subjected to constant current driving, is employed by a method wherein a voltage dividing circuit is formed by connecting a resistor between the output terminals of the Hall element. CONSTITUTION:Resistors Ru, Rv, Rw, having the same resistance value R, are connected to the output voltage terminals of Hall elements Hu, Hv, Hw while the output voltage terminals are connected to an IC 10 for driving a motor. When the internal resistance of the Hall element is high and the output voltage is high, the dividing ratio of a voltage, divided by an internal resistor and an external resistor R, becomes small and a voltage inputted into the IC 10 for driving motor is contracted. When the internal resistance of the Hall element is low and the output voltage is low, the voltage dividing ratio between the internal resistor and the external resistor R is increased and the voltage, inputted into the IC 10 for driving the motor, is increased relatively. According to this method, the voltage, inputted into the IC 10 for driving the motor, is averaged inspite of the variety of the Hall element.
