Title: Shell wall of nuclear reactor building
Inventor: KAMEI HIDEAKI
IPC: E04H7/00
Filed: 1988-03-24
Abstract: PURPOSE:To facilitate reinforcement construction such as the working and assembly of reinforcing bars, formwork, and concrete construction and to shorten the construction period and to reduce the cost by forming the upper part of the shell wall corresponding to the spherical shell part at the upper part of a reactor container in a cylindrical shape. CONSTITUTION:A nuclear reactor pressure vessel 2 is installed in the center part of the nuclear reactor building 1 and the outside of the container 3 is covered with the shell wall 4 made of reinforced concrete. This shell wall 4 consists of a small-diameter cylinder part 4a and a large-diameter cylinder part 4b in a two-stage cylinder shape, and this step part is formed at the position corresponding to the upper spherical shell part of the container. The thickness of the shell wall 4 is made uniform. In this constitution, when the shell wall 4 is structured, none of longitudinal bars 6, 6... is curved because of there is no three-dimensional curved surface in the reinforcement construction, and lateral bars 7, 7... are only curved with the same curvature as the cylinder part 4b. Further, the longitudinal bars 6, 6... are equal in pitch to the cylinder part 4b at the part where the spherical shell part 5 is formed and not changed in shape at the upper parts.

Title: Photographic printing exposure deciding method
Inventor: OSONO CHIAKI
IPC: G03B27/72
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain high yield by appropriate printing regardless of the change of photographic exposure by calculating plural image characteristic values by performing at least two different kinds of weighting to two-dimensional image information. SOLUTION: The average transmitted light beams of the respective colors B, G and R of an original picture are received by photodiodes 44a to 44c through the photometric filters 42a to 42c of the colors B, G and R. The photometric signals of the colors B, G and R obtained by photoelectrically converting the received light quantity are supplied to an exposure control part 30 and A/D converted, and exposure is calculated based on the conversion data and correction quantity supplied from an information processing part 26. Namely, plural image characteristic values deciding printing exposure are obtained from the image information obtained by performing at least two different kinds of weighting to the two-dimensional image information on three surfaces of B, G and R of the original picture. Therefore, the use of the image characteristic values depending on the photographic exposure is avoided and the exposure width of the appropriate printing becomes small and high yield is obtained regardless of the change of the photographic exposure.

Abstract: PURPOSE: To minimize pressure loss in an evaporator by making gradual reduction in size of diameter of powdery metal particles to be sintered along the direction of flow of heating fluid in a heat-conducting element so that density at foam-generating point can be gradually increased and volume steam generation can be made uniform.  
     CONSTITUTION: A heating fluid 10 having flowed in from a heating fluid inlet 20 of an evaporator 12 is allowed to conduct heat exchange with a low boiling point media while passing through inside of a heat-conducting pipe 24, lowered its temperature gradually and discharged from an outlet 22 to outside of the system. On the other hand, the low boiling point media having flowed in from a low boiling point media inlet 22 makes heat exchange with a heating fluid flowing in the heat- conducting pipe and undergoes pool boiling. Particle diameter of metal powder is reduced and sintered along the direction in which the heating fluid flows on the exterior surface of this heat-conducting pipe 24. In this mechanism, density at foam- generating point can be increased along the direction of flow of the heating fluid and thereby volume of steam generation becomes uniform.

Title: Automatic color temperature correcting circuit for video camera
Inventor: SUZUKI SATOSHI
IPC: H04N9/07
Filed: 1985-04-05
Abstract: PURPOSE:To make it possible to obtain much more appropriate color temperature correction in a specific condition by fixing the output voltage of an automatic color temperature correction circuit at a regulated value for optional time by a photographer's will. CONSTITUTION:So that the output impedance of the fourth operational amplifier 8 is very small when a switch 19 is closed, the output voltage at the output terminal O of the fifth operational amplifier 21 is rapidly followed to the color temperature fluctuation of an object. On the other hand, so that the input impedance of a voltage follower that uses the fifth operational amplifier is very large when the switch 19 is opened and with selecting the large capacity of a capacitor 20, the output voltage at the terminal O is held at the value just before when the switch 19 is opened. Therefore, by opening the switch 19, the photographer can hold the output voltage of the automatic color temperature correction circuit at the regulated value for the optional time. Especially, even when there is a large difference between the color temperature of the object to be photographed and that of a background, the color temperature of the object is corrected at the most appropriate condition.
