Filed: 1989-09-13
Abstract: PURPOSE: To reduce the noise band of a modulated chrominance signal without deteriorating a differential gain or differential phase component correlated to a signal by sampling a signal during the period of a test signal regularly existing in a vertical direction like a full field or a single line. CONSTITUTION: A video input signal is inputted to a 1st attenuator 30 having an attenuation ratio 1-a and an attenuated signal is inputted to an adder 32. A signal passed through a delay circuit 34 and a 2nd attenuator 36 is added to the output of the attenuator 30. The attenuation ratio of the 2nd attenuator 36 is (a) and the delay time of the circuit 34 is equal to a horizontal video line period. Input data are sampled during the period of an active video part of the input signal and sampled data in continued lines or respective lines corresponding to respective frames are accumulated. A filter adds a part correlated to the vertical direction of the input signal to average the noise components of the input signal. Consequently a signal-to-noise ratio is improved without deteriorating the input signal and the measurement of an accurate differential error is improved.

Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To prevent the midpoint (operation point) of the output level of a differential amplifier from fluctuating by changing the voltage of a well voltage input terminal in accordance with the current value of a constituent current source. SOLUTION: The source electrodes of the first and second NMOS transistors 1 and 2 whose source electrodes are connected are connected to the constant current source 3 increasing/decreasing the current value by the voltage of a control voltage input terminal 12.

The voltage of the well voltage input terminal 13 can be changed in accordance with the current value of the constant current source 3. When the current value of the constant current source 3 is small, the low output level of the differential amplifier rises and a high output level drops. When the current value of the constant current source 3 is large, the low output level drops and the high output level rises.

IPC: C10N40/14
Filed: 1993-08-31
Abstract: PURPOSE:To synthesize extremely stable submicron particles of electroviscous fluid by using an organic functional group-modified silicone oil as a dispersing agent in dispersing a hydrophilic monomer into silicone oil of disperse medium and polymerizing the monomer. CONSTITUTION:When hydrophilic polymer fine particles are synthesized in reverse micelle or water-in-oil type microemulsion obtained by dispersing a hydrophilic monomer into a disperse medium consisting of hydrophobic liquid, the synthesis is carried out using silicone oil as the disperse medium and an organic functional group-modified silicone oil as a dispersing agent, respectively. When the hydrophilic monomer is dispersed, ultrasonic wave is applied thereto. In this time, a dispersing apparatus having an ultrasonic wave-oscillating part formed using a nonmetallic material as the surface is used. As the monomer, either one compound of an acrylic acid (metal salt) and a methacrylic acid (metal salt) or a monomer copolymerizable therewith is used. An electroviscus fluid is produced using the resultant polymer fine particles as a disperse phase.
