Title: Color image pickup device
Inventor: TAKANASHI RYOYU
IPC: H04N9/07
Filed: 1987-01-08
Abstract: PURPOSE:To contrive to reduce the break of white balance at a bright part of an object by compressing a color signal at a high brightness and a low saturation part of an object based on a luminance signal component and a chrominance signal component obtained from an output signal of an image pickup tube. CONSTITUTION:A chrominance signal Sc fed to an input terminal 1 and a luminance signal Sy fed to an input terminal 2 are fed to a subtractor SUB, and a difference signal Sc-Sy is fed to a control signal generating circuit SPG from the subtractor SUB. When the signal Sc-Sy exceeds a threshold value, the circuit SPG gives a control signal Sp to a changeover switch Sw. In receiving the signal Sp, the switch Sw turns its fixed contact from the position (a) to the position (b) to give a reference voltage Es as a signal Se to an adder ADD. The adder ADD adds the signal Sc and the signal Se to output an output signal So=Sc+Se. Thus, the highly bright and low saturation portion of the object is compressed and color shading or color unevenness appearing in the reproduced picture is reduced.

Title: Data compressing/restoring device and method using additional code
Inventor: SATO NOBUKO
IPC: G06F17/30
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To compress data expressed with codes with a high compression rate, and to restore the compressed data from an arbitrary position. SOLUTION: The codes of the 'compressed', 'to be', and 'data' in an input character string 'CAD data to be compressed' are converted into word codes '0x8260', '0x0011', and '0x8261' as registered words respectively. In this case, words starting with 'C', 'A', and 'D' are not registered in a dictionary, then those characters are divided into one byte units, and outputted after an additional code '0xFF' is added to the front part of each obtained part. In the restoration, whether or not they are the word codes is discriminated, based on the additional codes.

Abstract: PURPOSE:To perform accurate demodulation even when the variation width of a carrier frequency is large by measuring the rising period of a demodulated signal and the interval from the rise to the fall, and finding the degree of modulation from a specific equation. CONSTITUTION:The rising period T of the modulated signal and the interval (t) from the rise to the fall are measured and the degree of modulation is found from the equation I.

Abstract: PROBLEM TO BE SOLVED: To eliminate the dead-zone quantity of a control valve resulting from a secular change by finding the dead-zone quantity of the control valve by inputting the output signals of a multiplier and a learning device which finds and outputs the dead-zone quantity of the control valve at which the acceleration variation of a cylinder rod becomes the minimum to a relay calculator. SOLUTION: A multiplier 14 obtains an output signal V by multiplying a deviation signal E outputted from a subtractor 18 by subtracting a feedback signal Y from a sensor from a command signal R by a gain K. The output is divided into two parts and one part is inputted to a relay calculator 16, with the other part being inputted to an adder 19. The relay calculator 16 outputs the positive, negative, or zero dead-zone quantity of the output signal V of the multiplier 14. The dead-zone quantity uses acceleration variation ΔG from the sensor and the spool variation of a control valve outputted from a learning device 17 when the device 17 inputs velocity variation ΔVel, namely, the dead-zone quantity ΔX of the control valve.  An adder 19 adds the output signal of the calculator 16 to the output signal V of the multiplier and outputs the added signal Vn to the control valve through a current converter 15.

Abstract: PROBLEM TO BE SOLVED: To defoam even a liquid such as a photographic emulsion and also to avoid flocculation of an additive by transferring ultrasonic vibration of a frequency change cycle changing from vibration of low frequency to that of high frequency by one frequency change cycle or more. SOLUTION: Drive control is performed in such a manner that after an oscillator drive controller 8 vibrates an ultrasonic vibrator transducer 7 at the minimum frequency for several seconds every frequency, the vibration is carried out at a high frequency, and after vibration at a low frequency, the vibration is carried out at a high frequency. A photographic emulsion is prepared in a liquid storage tank 1, and heated water is passed through a jacket 6, and the transducer 7 is vibrated by the oscillator drive controller 8 for 30min by making one cycle of 28kHz→45kHz→100kHz for 5sec every frequency 15sec, allowing ultrasonic vibration to be transferred to the photographic emulsion in the liquid storage tank 1 to perform defoaming.  As a result, a photographic emulsion in which defoaming is complete and the flocculation of an additive is eliminated is obtained, and the emulsion thus obtained is uniformly applied to a photosensitive material base.
