Filed: 1990-03-27
Abstract: PURPOSE:To accurately detect noise quantity mixed in a video signal without being affected by ghost or the like by adopting the constitution such that a noise signal is averaged by different averaging number of times and the noise quantity is detected from the difference. CONSTITUTION:A difference signal outputted from a difference detection circuit 6 is fed to an N time averaging circuit 21 and an M time averaging circuit 23 and a mean value of a difference signal is calculated only for a period when a ghost elimination reference (GCR) gate signal is obtained. The GCR signal is included in each averaging signal in addition to the noise signal, and an M time averaging value Ma, that is, a difference signal with less noise component is outputted to a terminal 27 and fed to an adder. Moreover, the average signal is fed to absolute value calculation circuits 22, 24 respectively, in which the signal is subjected to absolute value processing. The absolute value signals Sn, Sm are fed to an adder 25 and added by the polarity as shown in Figure.

Filed: 1982-05-13
Abstract: PURPOSE:To permit a rotary body to be provided with a rotational force proportional to a driving torque by installing a piston cylinder unit which press a frictional driving body onto the rotary body by the pressure substantially proportional to the driving torque generated in a hydraulic motor. CONSTITUTION:A hydraulic motor 21 is driven by driving a hydraulic pump 23, and a roller 16 is revolved. As the roller 16 and a frictional flange 7 are frictionally engaged, a rotary body R revolves. When the pressure of the pressurized oil supplied to the hydraulic motor 21 increases, a piston cylinder unit 17 pulls a casing C leftward as shown in the drawing, and the roller 16 and the frictional flange 15 are pushed by the force proportional to the hydraulic pressure. Therefore, as the hydraulic pressure increases, the frictional force on the engagement surface increases, and a frictional force proportional to the driving torque can be obtained.

Title: Fuel injection controller
Inventor: SUGIURA TAKAYUKI
IPC: F02D21/08
Filed: 1988-03-31
Abstract: PURPOSE:To maintain the superior operation state of an internal combustion engine by correcting the variation quantity of the air-fuel ratio which is calculated from the variation quantity of the intake pipe pressure due to the recirculation of the exhaust and setting the obtained value as aimed air-fuel ratio. CONSTITUTION:During the time when an exhaust recirculation device 40 operates to allow exhaust to recirculate into a manifold intake passage 16, a control means 80 turns OFF a control pressure selector valve 62 of EGR modulator 60 for a prescribed time when the NOx does not vary, in other words stops the recirculation of exhaust and detects the variation quantity of the intake pipe negative pressure. The EGR rate is calculated in accordance with the variation quantity of the intake pipe negative pressure, and the variation quantity of the air-fuel ratio due to the recirculation of the exhaust is calculated according to the EGR rate. Then, the fuel injection quantity is controlled so that the variation quantity of the air-fuel ratio is corrected to set as an aimed air-fuel ratio (air-fuel ratio in the case when exhaust is not allowed to recirculate). Therefore, even in the case when the exhaust is allowed to recirculate into the manifold intake passage 16, the aimed air-fuel ratio can be maintained, and the superior operation state of an internal combustion engine 2 can be maintained.

Title: Continuous casting method for large-section slab
Inventor: TAKASE KENJI
IPC: B22D11/115
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the skinning at the meniscus in a low pouring weight of molten steel and the falling down of a shell at the time of low-speed casting without using a protective layer of ceramics, etc., by executing the continuous casting of a large-section slab of a specific thickness by subjecting the molten steel in a casting mold to electromagnetic stirring. SOLUTION: A swirling flow velocity is imparted to the molten steel near the meniscus by electromagnetic stirring devices 2, 2a installed in the upper part of the rear surfaces of long copper plates 1, 1a of the casting mold. In the low-speed casting of the large-section slab having a thickness of >=400 mm, the swirling flow may be formed by subjecting the molten steel in the casting mold to electromagnetic stirring, by which heat is uniformly supplied to the meniscus without requiring the selective use of the shape of an immersion nozzle and the skinning is prevented even under conditions of different thicknesses. In addition, the growth of the shell near the meniscus is suppressed and the falling down of the solidified shell 3 is lessened by the washing effect of the solidified shell 3 by the swirling molten steel flow.  In addition, the degradation in the internal defect by the inclusion of powder does not occur.

Title: Driving device for electrostatic converting means
Inventor: TOMIKAWA YOSHIRO
IPC: G01C19/5776
Filed: 1995-03-09
Abstract: PURPOSE: To enable power saving driving by eliminating or reducing power consumption of damping capacity elements for piezoelectric vibrator when the piezoelectric vibrator is to be driven. CONSTITUTION: A piezoelectric vibrator 1 is vibrated/driven at a constant voltage by an AC driving power supply 5. An electrostatic capacity Cs equivalent to the damping capacity Cd of the vibrator 1 and a phase converting means 6 for changing by 180 deg. the phase of a current flowing in the capacity Cs are connected in parallel with the vibrator 1. Thus, the current flowing in the capacity Cd can be equivalently eliminated or reduced, resulting in reduction of current consumption. In addition, since no coil is given thereto, the effect of eliminating current by the capacity Cs hardly depends on frequency. Therefore, even when the frequency of driving power from the power supply 5 deviates from the resonant frequency of the piezoelectric vibrator, a similar power saving effect can be exhibited.
