IPC: F16F15/16
Filed: 1986-03-20
Abstract: PURPOSE:To damp the nutation of a rotary unit and to enable its stable rotation to be obtained, by mounting a hollow annular vessel to the high speed rotary unit concentrically with its rotary shaft and sealing the vessel, which provides space to be left in the inside, with viscous fluid of volume 1/2 times or less the volume surrounded by the peripheral wall part of the vessel. CONSTITUTION:A hollow annular vessel 3, which is mounted to a high speed rotary unit 1 concentrically with its rotary center axis, is sealed with viscous fluid 4 providing space to be left inside the vessel 3, and the volume of the viscous fluid 4 is set to a value 1/2 times or less the volume surrounded by the peripheral wall part of the vessel 3. Then the high speed rotary unit 1 causes by its rotation the viscous fluid 4 in the vessel 3 to rise up along the peripheral wall by centrifugal force, and a wave, called a centrifugal wave, is generated in the viscous fluid 4 in the same direction to the rotation. If the frequency of said centrifugal wave is set so as to be almost equal to the nutation frequency of the rotary unit 1, nutation energy is absorbed and damped by the centrifugal wave. Accordingly, the rotary unit 1 can be stably rotated.

Title: Video signal processing circuit
Inventor: URATA EIKICHI
IPC: H04N9/69
Filed: 1993-03-23
Abstract: PURPOSE:To allow the circuit to cope with a video signal of a different system by inputting a video signal with a blanking signal added thereto to a RAM, discriminating the signal system and executing gamma correction and black level correction to the signal of each system. CONSTITUTION:A signal converted into a primary color signal at a matrix circuit 2 is added with a blanking signal and the result is inputted to a RAM 4. A control section 5 discriminates whether an input signal S1 is a signal of the NTSC, MUSE or PAL system and calculates gamma correction value and black level correction value in matching with the signal of the system and writes the result to the RAM 4 as the address. Thus, the video signal with the blanking signal added thereto is subject to gamma correction and black level correction in matching with the signal system in the RAM 4. Then the signal corrected by the RAM 4 is outputted via an enhancement adder circuit 6 and a synchronization adder circuit 7. Thus, the processing circuit copes with the video signal of the different system.

Title: Indirect measuring device for width of pulse of ultrashort optical pulse
Inventor: OTA HIROYUKI
IPC: G01J11/00
Filed: 1994-03-31
Abstract: PURPOSE:To obtain a time resolution in high accuracy by accurately converting the width of the pulse of an incident ultrashort optical pulse. CONSTITUTION:A super-short optical pulse is divided into the first and second ultrashort optical pulses with a half mirror. The first ultrashort optical pulse is emitted as the first parallel beam through a fixed prism and a half mirror and condensed on a nonlinear crystal with a lens. The second ultrashort optical pulse is emitted as the second parallel beam through a movable prism stage 13 and the half mirror and condensed on the nonlinear crystal with the lens. The first and second parallel beams generate the second higher-harmonic signal light in the nonlinear crystal with the relative time difference tau, which is imparted with the movable prism stage 13. The second higher-harmonic signal light is detected by a photodetector means. An auto-correlation waveform detecting means detects the auto-correlation waveform of the ultrashort optical pulse based on the output signal of the photodetector means. A laser-type displacement gage 14 measures the displacement of the movable prism stage 13 with respect to time. A correcting means corrects the auto-correlation waveform based on the result of the measurement of the displacement measuring means.

Filed: 1981-04-30
Abstract: PURPOSE:To remove the torque ripple of a DC motor by controlling an armature current so that the product of a field magnetic field crossing with an armature coil and an armature current becomes constant. CONSTITUTION:A bridge circuit is composed of resistors 2, 3, 4 and a DC motor 1, and a differential amplifier circuit 8 connected to the output terminal of a bridge circuit outputs the counterelectromotive force E of the motor 1. An operational amplifier 24 inputs a constant voltage corresponding to the designated rotating speed applied to a terminal 25 and the counterelectromotive force E of the motor 1, smooths the output signal via a capacitor 28, and applies it to a divider 7. The divider 7 outputs a signal obtained by dividing the output signal of an operational amplifier 24 by the counterelectromotive force E. An operational amplifier 6 applies a base current responsive to the difference between the voltage drop of the resistor 2 and hence the armature current I and the output of the divider 7 to a transistor 5.

Abstract: PURPOSE:To improve quality and reliability by incorporating a high-polymer compd. which has the chemical structural group having affinity to each of coloring materials and resins within the same molecule into patterned coloring resin layers. CONSTITUTION:The high-polymer compd. which has the chemical structural group having the affinity to each of the coloring materials and resins is incorporated into the patterned coloring resin resins. The form of good dispersibility is, therefore, obtd. in case of dispersing the coloring materials into the resin. The color filters which are good not only in color characteristics but also the uniformity, etc., of the films and have less defects are obtd. Further, the patterned coloring resin layers attain the form of incorporating the impurities contained in the coloring materials into said layers when said layers are formed of the coloring resins formed by using the coloring materials previously subjected to the surface treatment by the high-polymer compd. The influence of the impurities from the patterned coloring resin layers formed by using the coloring materials to the device (element) is thus suppressed. The quality and reliability are thereby improved.
