Title: Temperature measuring apparatus for steel pipe
Inventor: KOMIYA YOSHIOKI
IPC: G01J5/10
Filed: 1995-06-13
Abstract: PURPOSE: To obtain a temperature measuring apparatus which can measure the temperature in the circumferential direction of a steel pipe with good accuracy in a simple constitution, in which a slip ring or the like is not required, which is low-cost and which prevents the generation of a noise or the like by making the angle of rotation do not exceed a specific value. CONSTITUTION: Radiation thermometer sensors 2-a, 2-b which measure the surface temperature of a forge-welded tube 1 are attached to positions which are symmetric with reference to the shaft of a sensor holder 3, the holder 3 is turned by 180 deg.C by means of a circling mechanism 4, and a temperature at 180 deg.C can be measured by one sensor. Since a measuring hole 18-b for the sensor 2-b which measures the lower half of the forge-welded tube 1 is worked so as to face the rotation central axis of the sensor holder 3 and to tilt to the front and rear directions of the holder 3, the scale of the tube, cooling water and the like do not fall into, and adhere to, the measuring hole. Radiant light, from the steel tube, which has passed respective measuring holes 18-a, 18-b is reflected by a reflecting mirror 23 and enters the light receiving part of a radiation thermometer 8.

Title: Magnetic recording medium/device and magnetic recording method
Inventor: YOSHINARI JIRO
IPC: G11B5/65
Filed: 1988-06-14
Abstract: PURPOSE:To eliminate the influence of an external magnetic field and to improve the stability with the title medium/device and method by using a ring of a superconductive material to form a magnetic recording part, applying a magnetic flux into the ring in a normal conductive state and then setting in a superconductive state to make a center hole catch the magnetic flux for execution of a recording job. CONSTITUTION:A mask having the concentrical patterns is formed on the surface of a base body 2 by a photoetching process. Then a ceramic superconductive film is formed on said patterns by a sputtering process. Then the mask is removed, and obtained a recording medium 1 having the concentrical superconductive rings 3. A magnetic flux is applied to the medium 1 in a normal conductive state by means of a laser light source 11, a recording head 12 and a superconductance interferometer 13. Then the medium 1 is cooled down to 30K and set in a superconductive state. As a result, the magnetic flux of an integer multiple as much as the magnetic flux quantum is caught at a center hole 31 of each ring. Thus it is possible to obtain a magnetic recording medium which is free from the influence of an external magnetic flux and also magnetically stable.

Title: Nuclear reactor pressure vessel cooling device
Inventor: SUZUKI KENICHI
IPC: G21C13/00
Filed: 1990-06-05
Abstract: PURPOSE:To prevent a nuclear reactor pressure vessel from breaking by circulating cooling water in the space between the nuclear reactor pressure vessel and steel-made container from a pressure suppression system through a remaining heat removal system in emergency. CONSTITUTION:When abnormality occurs, the device is put in operation automatically or manually to inject the cooling water in a pressure suppression chamber 6 or condensate storage tank 13 into the space 3 between the nuclear reactor pressure vessel 2 and steel-made container 4 through injection piping 11. Consequently, a damaged reactor core deposited on the lower plenum of the pressure vessel 2 is cooled. The cooling water is sent back to the suppression chamber 6 through discharge piping 12 scooped up again by a remaining heat removal system pump 9, and cooled gradually by a remaining heat removal system heat exchanger 10 and injected into the space 2 again. Further, even when the pressure vessel 2 breaks directly, the cooling water in the pressure vessel 2 can be recirculated to the reactor core 1 only by flowing out of the breakage place into the space 2 to terminate an accident.

Abstract: PURPOSE:To improve the sensitivity and withstand voltage of the semiconductor device the main current of which is controlled by electricity or optical signals by a method wherein the successive layers exceeding three layers are provided and the semiconductor elements of the layers are formed into conductors with alternately different shapes. CONSTITUTION:When the voltage is impressed between the emitter terminal 13 and the collector terminal 14 of a transistor assuming the collector side to be positive, the p-n junction between p type embedded layer 11 in the collector  layer 3 and n type collector layer 3 is in the inversed bias status and as far as  the impressed voltage is lower, the collector layer 3 is not completely disconnected by the depletion layer around said embedded layer 11 to be conducted  by the incident light over the base layer 2 just like the conventional phototransistor. When the voltage impressed between the emitter terminal 13 and the  collector terminal 14 is further boosted, the depletion layer around said embedded layer 11 is expanded in the collector layer 3 making the embedded layer 11  work just like the gate layer of the joint type field effect transistor to disconnect the the collector layer 3 making the carrier unalbe to pass thereby improving the withstand voltage between emitter and collector.

Then, the substrate is heated in a vacuum for five minutes, and a CoSi2 film 114 is formed on a region where the Co film 111 comes into contact with silicon. Then, the substrate is subjected to a rapid thermal treatment(RTA) in a nitrogen atmosphere at a temperature of 500 deg.C for 30 seconds to change the CoSi2 film 114 in phase, whereby a CoSi film 115 20nm in thickness is formed. Then, an unreacted Co film 111 on the insulating film is selectively removed by wet-etching with a mixed solution of sulfuric acid and hydrogen peroxide. Then, the substrate is subjected to a rapid thermal treatment (RTA) in a nitrogen atmosphere at a temperature of 800 deg.C for 10 seconds, whereby the CoSi film 115 is changed in phase into a CoSi2 film 116 of thickness 35nm or so.

Title: Reactor core of nuclear reactor
Inventor: HIDA KAZUTAKA
IPC: G21C3/326
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To improve fuel economy by increasing the ratio where the total of a fuel assembly with the longest residence period in a reactor and that with the second longest residence period occupies in the outer periphery and the second layer-region as compared with that for occupying in an internal region. SOLUTION: In the reactor core of a boiling-water nuclear reactor or the like, the outermost periphery region is arranged while fuel at the fifth cycle occupies all, and the second-layer region is arranged while fuel at the fourth cycle occupies all, thus reducing the leakage of neutrons from the reactor core. The fuel at the fourth cycle is also loaded into a control cell for composing a control region. The second-layer region is separated from the control region by a third-layer region to prevent the decrease in output due to the insertion of a control rod during operation from affecting the second-layer region.  The total of the fuel at the first cycle and that at the second cycle is for example approximately 80% at the third-layer region and is larger than the total of the fuel at the first cycle and that at the second cycle excluding the third layer out of the inner region, thus flattening an output distribution in a diameter direction.
