Title: Image processing method, system, recoding medium, image pickup device and image reproducing device
Inventor: TAKEMURA KAZUHIKO
IPC: H04N1/60
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain the same impression of an image resulting from reproducing image data seen as that of an original scene at the time of acquiring the image data. SOLUTION: Image data S are read from a recoding medium 1 and given to an image processing means 3. A color conversion section 5 converts 3-stimulus values of each pixel in an image represented by image data into a chromaticity value and a mean value calculation section 6 obtains a mean value of chromaticity values. A physiological primary color conversion section 7 converts the mean value of the chromaticity values into a physiological primary color. This physiological primary color is regarded to be a white color of a photographing light source in a photographing state. A chromatic adaptation conversion section converts the chromaticity obtained by the color conversion section 5 so that the physiological primary color obtained by the physiological primary color conversion section 7 is coincident with the physiological primary color of a reference photographing light source.  An RGB conversion section 9 converts the converted chromaticity values into an RGB color signal and an output section 10 applies image processing to the color signal and a reproduction means 4 reproduces the signal as a visual image.

Title: Produciton of forming glass material and optical element
Inventor: YOGO TAMAKAZU
IPC: C03B40/02
Filed: 1991-03-12
Abstract: PURPOSE:To prevent the cracking of a glass when formed and the contamination of the formed article and mold at the time of producing a glass material for press-forming an optical element by dipping the glass material in acid, and then heating the material under reduced pressure or in a dry atmosphere. CONSTITUTION:A glass material (e.g. silicate glass) used for press-forming an optical element is dipped in acid (e.g. nitric acid) to elute the component soluble in acid from the glass surface as a cation (e.g. Na<+>), the hydrogen ion of acid is diffused instead into the glass to exchange the cation, and a porous hydrated layer rich in SiO2 is formed on the glass surface. The glass material is then heated under reduced pressure or in a dry atmosphere to cause dehydration and condensation in the hydrated layer, hence the network structure of Si-O-Si is formed, and a dense glass layer rich in SiO2 is formed on the glass surface. Consequently, when the treated glass material is press-formed into an optical element, the fusion of the formed article to the mold member, the contamination due to the volatilization of the glass component, etc., are prevented.

Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To combine responsiveness and converging accuracy in adaptive control so as to improve intake-exhaust noise muffling performance by changing the operating quantity according to the converging degree of the characteristic control value in an adaptive control means. SOLUTION: A microphone 51 is provided on the engine 50 side of a duct 56, and a microphone 52 is provided near an open end. When the output of intake-exhaust noise detected by the microphone 52 exceeds a judgment level, a control unit 63 constituted including an adaptive digital filter 53 first changes each filter coefficient of the digital filter 53a by adaptive control and then processes a detection signal of the microphone 51 to drive a speaker 54. At this time, when the filter coefficient continuously changes to increase or decrease, a step size (operating quantity) is gradually enlarged. In the case of the changing direction of the filter coefficient being reversed, the step size is corrected to be small.

Abstract: PURPOSE:To easily detect the abutting center position of a light pen by differentiating a light pen output signal made of plural pulses and detecting a timing when the level of the differentiated pulse passes by a reference value as the abutting center position of the light pen. CONSTITUTION:The differentiation pulse dLP2'' in the visual field of the light pen is composed of plural differentiation pulses, and a point C in the tailing part of the differentiation pulse dLP2m'' having the maximum level approximately corresponds to the center in the visual field of the light pen.

Title: Fluidized-bed incinerator
Inventor: KIKUOKA KAZUMA
IPC: F23C10/24
Filed: 1983-04-23
Abstract: PURPOSE:To make it possible to discharge foreign matters out of the burner during the operation of the burner even when the foreign matters are contained in fuel by slantly forming a porous plate and providing a discharge port. CONSTITUTION:In a case where quartz sand is used as a fluidizing medium, the apparent specific gravity of the entire part of a fluidized layer becomes approximately 1 by being fluidized. Hence, foreign matters in the fuel precipitate and reach the porous plate 2. Since the porous plate 2 is inclined, the foreign matters 17 on the porous plate 2 move toward a discharge port 4, and finally they are discharged out of the burner through the discharge port 4 and a discharging device 7. Further, a device of a type in which an air chamber 2 is divided into two parts by the discharge port 4 has an advantage in that the device can be operated at an extremely low load by fluidizing only a part of the layer by stopping air supply to one of the divided air chambers.

Further, a sub-data signal CH3 is obtained by multipliers 10-12, a low pass filter 13, an identification device 14 and an NOT circuit 21. Output signals 108-111 are obtained from the signals P, Q at the main data reproducing section through analog switches 15, 16, an adder 19, a subtractor 20 and an NOT circuit 23. The signals 110, 111 are obtained when an output of a locking phase discriminating circuit 22 is zero and in-phase to the signals P, Q.
