Inventor: SATO TSUNEO
IPC: H04N1/60
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To obtain color characteristic data with high accuracy by configuring a multi-dimensional lookup table only with characteristic points that are points denoting relation of input and output image signals discriminated to be impossible expansion in the table expansion processing in the case that image data in a color characteristic lookup table are expended in the multi-dimensional lookup table. SOLUTION: A color characteristic description device 2 generates color characteristic data of an image input device 1. A data processing section 3 converts photographed image in the image input device 1 into an image data signal. A combiner 4 combines the color characteristic data and the image data signal into data with an image data format. A separation device 11 separates the image data transmitted from the image data with the data format into the image data signal and the color characteristic data. An image data conversion processing means 15 uses a multi-dimensional lookup table LUT: 14 expanded by a table expansion processing means 13 to convert the input image data separated by the separation device 11 into output image data. An image output device 10 processes a signal outputted from a color management device 16 and prints out the processed signal.

Abstract: PURPOSE:To promote the ignition of pulverized coal by a method wherein a pulverized coal nozzle and a secondary air nozzle are installed coaxially and the cross sectional area of a secondary air passage in the secondary air nozzle is formed eccentrically with reference to a coaxial center. CONSTITUTION:A pulverized coal nozzle 16 has an elliptical cross sectional shape, and thereby the cross sectional area of a secondary air passage in a secondary air nozzle is formed eccentrically with reference to a coaxial center. At the tip of the nozzle 16 a diffuser-shaped flame holding device 21 is placed. At the center of a burner 10 an auxiliary fuel nozzle 15 burning auxiliary fuel is attached. Thus, the secondary and tertiary air are spouted into a combustion chamber 11 as circular ring-shaped jet streams from the nozzle 17 and a tertiary air nozzle 18.

Title: Radio telephone system
Inventor: HAMADA MASASHI
IPC: H04M1/00
Filed: 1993-11-16
Abstract: PURPOSE:To avoid the recollision of retransmitted control signals by setting a control signal retransmission timer value to be used corresponding to information peculiar for a radio terminal at the radio telephone system to utilize the radio line of a multi-channel access system. CONSTITUTION:When the transmission request of a control signal on a control channel simultaneously occurs at a radio telephone terminal 1(KT1)120 and a radio telephone terminal 2(KT2) 121, the control signals from the KT1 and KT2 are collided in a space, the recognition of data is disabled at correspondent radio base stations 110 and 111, and an Ack signal corresponding to the control signal is not returned. Therefore, since both KT1 and KT2 can not receive the Ack signal, it is recognized that the transmitted control signals are erased by the spatial collision, and the control signals are transmitted again based on a retransmission timer value calculated from physical information at the time of initializing the terminal. In this case, since the retransmission timer value to be used takes a value peucliar for each radio telephone terminal connected to a communication system, the retransmitted control signals do not collide.

The water feed is stopped upon lapse of the set time and the water in the water tank 6 is discharged, by which the rice washing stage is complete. The water feed for the immersion is then started. The water flows from the top edge of the rice washing and immersing tank 6 when the tank is full of the water. This water is drained by gravity from a drain pipe 28 of a drain tank 7. The water is drained to end the immersion upon lapse of the set immersion time.

Abstract: PURPOSE:To make possible a fine wiring and to obtain chemically stable and highly reliable wirings as well by a method wherein a copper-arsenic alloy is used as a wiring material or a covering material for the exposed surfaces of copper wirings and a wiring pattern is formed. CONSTITUTION:A silicon oxide film 3 is formed on the surface of a silicon substrate 2 of a semiconductor chip 1 and wirings 5 consisting of a copper- arsenic compound or copper arsenic alloy thin film 4 are formed on the surface of this film 3. This manufacture is performed by sputtering using a copper- arsenic alloy as a target, but as the film 4 is strong to an oxidizing atmosphere, the surfaces of the wirings 5 are not oxidized and the prescribed wirings are formed. Moreover, as the melting point of this alloy is high and its specific resistance is low, the generation of an electro-migration is prevented. Thereby, s fine wiring is made possible and at the same time, chemically stable and highly reliable wirings can be attained.

Abstract: PURPOSE:To obtain an iron core structure whose earthquake-resistant property is excellent by a method wherein a heat-insulating insulator is sandwiched between a glass binding tape and metal objects such as a yoke, a clamp and the like and the glass binding tape is heated by using a beltlike heater. CONSTITUTION:When this transformer is assembled again in a site, a winding 1 is inserted into an iron core 2, an upper-part yoke 3 is assembled, and the upper-part yoke 3 is sandwiched between upper-part clamps 5 via insulators 4. While a tension is being applied, they are brought into close contact and fixed by winding a glass binding tape 6 on their circumference. At this time, heat-insulating insulators 7 are sandwiched between parts where glass binding tape 6 comes into direct contact with the upper-part yoke 3 or the upper-part clamps 5. A beltlike heater 8 is brought into close contact with the circumference of the wound and fixed glass binding tape 6; the glass binding tape 6 is heated and hardened. The heat-insulating insulators 7 restrain heat from escaping to a metal object whose heat capacity is large when the glass binding tape 6 is heated and hardened.

Filed: 1986-12-02
Abstract: PURPOSE:To output the definite number of photons, by controlling a neutral density (ND) filter by a pulse motor to set the transmissivity of the ND filter corresponding to each wavelength. CONSTITUTION:Incident monochromatic light 13 passes through an ND filter 16 to be split into two by a half mirror 15 and the split reflected monochromatic light 13c is inputted to a control A/D.D/A converter 19 through a reflecting mirror 23 and a light quantity detector 17. A pulse motor 26 is driven by the D/A converting signal from the converter 19 to control the angle theta of rotation of the filter. The transmitted monochromatic light 13b split passes through an emitting slit 21 to irradiate a specimen. Since the transmissivity alpha(theta) of the filter 16 can be set to an arbitrary value from 0 to 1 by the angle theta of rotation, the angle thetai of rotation of the filter 16 corresponding to each wavelength lambdai within a predetermined wavelength range is calculated from the relation between the angle theta of rotation and the transmissivity alpha(theta) and the angle thetaof rotation of the filter 16 to the wavelength lambdai of the monochromatic light 13 is set as thetai and the transmissivity of the filter 16 is set to alpha(thetai) to make it possible to make the number of the photons of emitted light constant.
