Title: Method and device for extending life of fuel assembly
Inventor: SHIMAMOTO MITSUYA
IPC: G21C3/06
Filed: 1993-03-25
Abstract: PURPOSE:To recover the ductility and corrosion resistance of a Zr alloy part of fuel assembly and to achieve long combustion by retaining the fuel assembly which has been burnt for a specific cycle or longer at a high temperature in vacuum and then releasing occluded hydrogen. CONSTITUTION:A fuel assembly 3 for a light-water reactor is burnt continuously for one year normally (1 cycle), is taken out and inspected at the time of periodical inspection, and then becomes a waste fuel in two to four cycles. After a lid 4 of a hydrogen release device 10 is removed and then the fuel assembly 3 is inserted at the time of the periodical inspection, an exhaust system pump 5 is operated for deaerating and evacuating the inside of a sealed container 1 from an exhaust pipe 6 and then energizes a heater 2 for heating and raising temperature. The temperature should be approximately 300-600 deg.C and the degree of vacuum should be approximately 10<-7>mmHg, thus releasing hydrogen absorbed in Zr alloy member including a clad pipe and recovering ductility. Further, a kind of annealing effect can be expected of the hydrogen releasing device 10 and ductility reduction due to the irradiation damage of the member can also be recovered.

Title: Adding device for additive for component control
Inventor: HIRATA KAZUHIRO
IPC: C22B9/10
Filed: 1980-07-31
Abstract: PURPOSE: To mix additives into molten metal with good efficiency by immersing the lower parts of vessels respectively contg. molten additives and additives into molten metal, pressurizing both vessels to allow the contents to flow out from a common outflow pipe into the molten metal.  
     CONSTITUTION: For example, Al is melted in a melting furnace 5 and while it is being weighed with a weight detector 7, it is poured into a metering hopper 6. On the other hand, while, for example, powder carbon is being weighed with a weight detector 15 from a main hopper 13, it is flowed down into a metering hopper 16 at a prescribed rate. The opening part of the outflow pipe 1a of a vessel 1 is closed with a steel made plug, and the molten Al is teemed into the vessel 1, and the powder carbon into a vessel 2. Next, a ladle 27 is moved upward by a lifter 28 to immerse the lower parts of the vessels 1, 2 into molten steel 29, thence a pump 25 is started to pressurize the inside of the vessels 1, 2 with an inert gas. Then, the plug is pushed and removed, and the molten Al and the carbon powder mix with each other and eject from the outflow pipe 1a into the molten steel 29, thus mixing with the molten steel 29 without floating onto the top surface of the molten steel 29.

Title: Television camera
Inventor: IKENO MASAHIKO
IPC: H04N5/335
Filed: 1986-05-06
Abstract: PURPOSE:To improve a sampling density by branching an optical path from an image forming optical lens to an image pickup device into plural optical paths and sampling information that cannot be sampled from a picture through one optical path among plural ones from pictures through the other paths apart from the one. CONSTITUTION:A half mirror 31 is displaced in parallel from a position 31a by a fine amount, and rays l3a-l3c make incident on a point displaced by P/2 from a point on which rays 12a-12c make incident in a solid-state image pickup device 2. When shutter means 61 and 62 select the 2nd optical branched path, the light l3b makes incident on a signal transfer area 81, whereby it is not detected as a picture signal. However, since the rays of light l3a and l3c make incident on picture elements 71 and 72, respectively, they are detected as picture signals. Namely, picture information that cannot be detected when the 1st optical path is selected can be detected by selecting the 2nd optical path. Thus the sampling density of the picture information can double substantially.

IPC: G10K15/04
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To save the capacity of a storage medium by storing data sent from a server to a storage medium when number of times managed by a transmission number management equipment satisfies a prescribed condition and allowing a terminal equipment to read the data when the data in response to an external request are stored in the stored medium. SOLUTION: When number of times managed by a transmission number management equipment 113 satisfies a prescribed condition, each terminal equipment 12 stores data sent from a server 11. Then each terminal equipment 12 reads data requested externally and provides an output. Thus, after a prescribed condition is satisfied, the data requested externally are not sent via a communication line 13 but data stored in a storage medium 121. In this case, since the data are not sent to a communication line, the communication cost is saved. Moreover, when the prescribed condition is not satisfied, since each terminal equipment 12 does not store the received data to the storage medium 121, the capacity of the storage medium 121 is saved. When the prescribed condition is satisfied, each terminal equipment 12 stores the data to the medium 12.

Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To make strength uniform without splicing and to cut the production cost, by opening both ends of flexible cylindrical body made from a single resin material and by forming a cut where overlapping pieces are formed which projects outward in the longitudinal direction of the cylindrical body. SOLUTION: Both ends 3, 4 of a cable protecting cover 1 formed flexibly in a cylindrical body 2 with a single resin material are opened. A cut 5 is formed in the longitudinal direction on one side of the cylindrical body and overlapping pieces 6, 6 which project outward solidly are formed on the cut. A diametrically enlarged part 7 of a horn shape is formed solidly on the one end part 3. Also, through-holes 8 are provided at a constant interval on the overlapping pieces 6, 6. The flexibility of the resin allows the cut 5 to be enlarged with stability. Thus, a plurality of the covers can be stacked, so that they become less bulky and can easily be handled when stored or transported.  When the cover is hooked at the through-hole 8 of the end part 4 and lifted with a rope for the installation on a cable, a plurality of the covers can be transferred in a stacked state to a high place as the larger-diameter part 7 functions as an anti-skid means.

Abstract: PURPOSE:To stably form a plated layer of a uniform thickness on the entire surface of each dielectric core including the hollows by putting dielectric cores each having plural hollows in a plating tank and by plating the cores while circulating a plating soln. in the direction of the hollows. CONSTITUTION:Plural dielectric cores 27 each having plural hollows 26 are fitted to a suspending jig 25 and immersed in a plating soln. 23 in a plating tank 21. Plural anode plates 28 are arranged at the lower part of the tank 21 so that they confront the hollows 26 in the cores 27 as cathodes. The plating soln. is spouted upward from a pipe 22 on the bottom of the tank 21 and passed through the hollows 26 to electroplate the cores 27.
