IPC: H04N1/04
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To surely correct the focal distance and the color of a film before the pre-scanning by setting the 1st condition after a partial image of the film is read, reading again the the film image under the 1st condition to set the 2nd condition, and fetching the film image under the 2nd condition. SOLUTION: A scanner device 1 reads an approximately center image part of the 1st frame of a film and detects the image density to decide a negative or positive film and then to set a focal distance. The same image is entirely read under an acquired 1st condition, and a parameter is set in relation to the exposure. The scanning is carried out to acquire the condition before the normal scanning, and the condition is decided before the pre-scanning and the main scanning. The object images are obtained via the negative and positive films F used for a silver salt type camera, a positive film MF containing a slide mounter, a color or monochromatic silver salt photo, etc., and an APS film.

Abstract: PROBLEM TO BE SOLVED: To extend a transmission distance by increasing exciting light power by Raman-amplifying exciting light of a specific band by a Raman amplifying light source of a specific band width in transmission in an optical fiber and amplifying signal light as an exciting light source. SOLUTION: An optical multiplexer/demultiplexer 4 is an optical multiplexer/ demultiplexer having characteristics transmitting a wavelength of near 1,550nm only in an input port 4a near 1430nm only in an input port 4b, and near 1,430nm to 1,550nm in an output port 4c. As a core diameter of a dispersion shift optical fiber 5 connecting the optical multiplexer/demultiplexer 4 and a Er dope optical fiber 7 is smaller than a normal optical fiber, Raman amplification is easy to occur, light near 1,530nm is Raman-amplified by exciting light of a Raman amplification light source 9 of 1,430nm during transmission in the dispersion shift optical fiber 5. Thereby, decreasing of exciting light power in transmission in an optical fiber can be filled, a distance in which exciting light reaches the Er dope optical fiber 7 can be extended.

Title: Apparatus for controlling precipitation basin
Inventor: WATANABE SHIYOUJI
IPC: B01D21/30
Filed: 1981-03-16
Abstract: PURPOSE: To properly control a total sludge amount in a processing system without suspending sludge in overflowed water by controlling the withdrawing amount of a precipitated solid substance corresponding to the detected value of turbidity in clarified water overflowed from a precipitation basin.  
     CONSTITUTION: The sludge concn. S of an overflowed water 3 is measured by a densitometer 10 and applied to a controle circuit 11 and the tolerance value Sc of the sludge concn. is applied to said control circuit 11 by a setting device 12. When a measured value S is reached to the set value Sc or more, a withdrawing pump 13 is driven and, when said value S is reached to the set value Sc or less, said pump 13 is stopped. By this operation, sludge is prevented from being flowed out from a precipitation basin 1 and calrified overflowed water can be always supplied as well as good sludge interface position is maintained to be able to secure the sludge required in the precipitation basin 1. Because excessive sludge with a high concn. can be obtained in a low flow amount, the load of a sludge treating process can be reduced.

Title: Half-submerged multibarrel ship
Inventor: SUGIMURA YASUSHI
IPC: B63B1/12
Filed: 1979-03-28
Abstract: PURPOSE: To prevent a half-submerged multibarrel ship from growth of trim or rolling during loading by rigging a bouy put in or out from one position of the ship whose upper hull above the water and lower hulls underwater are connected.  
     CONSTITUTION: An upper hull 1 above the water level and several lower hulls 2 of a half-submerged multibarrel ship are connected by struts 3. A buoy 7a is hydraulically put in or out from one position of the ship 6 to float on the water. Because the transverse section of each strut 3 on a water line is small for reducing the resistance, the half-submerged multibarrel ship has a short metacentric height, resulting in great trimming or rolling. When the ship is anchored, the buoy 7a is floated to decelerate the trimming motion.
