Filed: 1993-12-08
Abstract: PURPOSE:To reduce the locating error of the thunder occurrence position by judging the identity of electromagnetic waves received at a plurality of observation posts based on the frequency spectrum data of the electromagnetic waves generated by the occurrence of thunder. CONSTITUTION:Electromagnetic waves generated by thunder are received by antennas 1A-1C and receivers 2A-2C of observation posts A-C respectively, the frequency spectrums of received signals are measured by frequency spectrum measuring instruments 3A-3C, the time data when the signals are received are added, and the frequency spectrums are transmitted to an integrated data processing computer 6. The computer 6 checks the correlation among the frequency spectrums transmitted from the observation posts A-C, obtains the difference of the reception time on the signals having the same frequency spectrum, distances from the corresponding observation posts to the thunder occurrence position are calculated, and the thunder occurrence position is located. No erroneous judgment of the thunder occurrence position is made, and the locating error can be reduced nearly to zero.

Title: Detecting method of approach of thunderbolt point
Inventor: KATO GIICHIRO
IPC: G01W1/16
Filed: 1989-12-28
Abstract: PURPOSE:To detect correctly when the lighting is coming very close by detecting the sudden inversion of the electric field on the surface of the ground which indicates the strike of the lighting and comparing the value of the electric field immediately before the sudden inversion with that immediately after the sudden inversion. CONSTITUTION:When the thundercloud is coming, the negative corona current corresponding to the negative charge at the bottom of the cloud is increased. However, if the lighting comes from the thundercloud, the polarity of the corona current is suddenly inversed, with a considerable amount of the positive corona current running out. The negative charge at the bottom of the cloud is increased with the lapse of time and a current value of a microammeter 2 is decreased, passing 0, to be returned to the value before the strike of the lightning. A value Xa of the electric field before the sudden inversion is compared with a value Xb of the electric field immediately after the inversion. The larger an absolute value of the difference, i.e., ¦(Xb-Xa)¦ and a value of ¦Xb¦/¦Xa¦ are, the closer is the bottom of the strong thundercloud immediately above a protecting point. Therefore, it becomes possible to correctly detect that the lighting is approaching.

Title: Fuel assembly
Inventor: KOYAMA JUNICHI
IPC: G21C3/328
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To increase degree of take-out combustion and uranium weight without deteriorating a reactor core stability margin, a channel stability margin, and further a thermal merging, by setting relationship among an assembly average uranium concentration, a channel box inner width, and an interval between the inner wall of the channel box and the outermost-periphery fuel rod to specific conditions. SOLUTION: A fuel assembly is provided with a channel box 1, a fuel rod 2, and a prism-type water rod 3. Since a void coefficient changes according to concentration, a interval between fuel rods required for maintaining stability depends on the concection of the fuel assembly. A ratio a/w of an interval (a) between the inner wall of the channel box and an outer-periphery fuel rod to an inner width (w) of the channel box is used. The relationship between a concentration E (wt.%) and the ratio a/w ban be summarized as a/w>=1.33E-2.52%. When the concentration is increased by 1 wt.%, a void coefficient absolute value increases by 12%. On the other hand, when the ratio a/w is increased by 1%, the void coefficient absolute value decreases by 9%, so that ratio a/w needs to be increased by 1.33% for a concentration of 1 wt.% for maintain a void coefficient.
