摘要： PURPOSE:To suppress the piping vibration by furnishing a ring-shaped projection on the inner wall of a piping, changing the form of the intra-pipe distribution of circumferential flow speed toward the downstream, and changing the flow variation characteristics for this distribution, in particular the frequency of vibratory components toward the downstream region. CONSTITUTION:A piping 1 is equipped at the inner wall with a ring-shaped projection 2 having a triangular section, a ring-shaped projection having a partially circular section, or a ring-shaped recess having a triangular section. In case the pipe includes a large swirling stream, the flow once turns around the ring-shaped projection 2 largely to the back of the projection owing to a large centrifugal force generated in association with the flow, to then be restituted little by little, and thereby growth of flow variation is suppressed.

摘要： PURPOSE:To control the leakage of coolant by the use of the coolant by providing a coolant supply passage for controlling the leakage of the coolant from the gap between a channel box and a lower tie plate when a fuel assembly is charged in a reactor core. CONSTITUTION:An lower tie plate 3 is equipped with a fuel support part 4 and a lower nozzle 10 and a space 11 is formed like a cylindrical body in the inside of the nozzle 10. The support part 4 covers the upper part of the space 11, attached to the upper end of the nozzle 10 and has a rib 6 for mutually connecting many bosses 5 and neighboring bosses 5 having holes 7 in which the lower end plugs of fuel rods or water rods are inserted. Cooling water flowing-in holes 8 are formed by the outer wall of the bosses 5 and the side wall of the ribs 6. Further, the outlet of cooling water jetting holes 9 are arranged in parallel to the holes 7 and the outside face 16A of the tie plate 3 arranged on the utmost circumference. The axis center of the jetting holes 9 is inclined at an angle of theta to the outside side face 16A of the tie plate 3. Therefore, the leakage of the coolant from the tie plate 3 and a channel box can considerably be controlled.

摘要： PURPOSE:To attain the free and easy control of vibrations of a machine structure by delaying optionally the detection signal of the vibration of an object by a fixed time and then vibrating the object. CONSTITUTION:The displacement of an object 1 is extracted from a contactless vibration detector 2 in the form of a signal when the object 1 is vibrated. This extracted signal is delayed by a fixed time by a digital delay circuit 3 and extracted as a current delay signal. An electromagnetic oscillator 4 gives vibrations to the object 1 with the electromagnetic vibration force proportional to said current signal. The conditions under which the object 1 is kept under an oscillation state or an oscillation absorption state are related with the time delay alpha and the number (f) of vibrations. Thus the larger the number of vibrations, the wider the range of conditions of the delay alpha set under the corresponding state. It is desirable to set a power amplifier 5 after the circuit 3.

摘要： PURPOSE: To permit to keep a flame effectively and effect the lower NOx combustion in a combustion chamber at the head of a combustor by a method wherein fuel is injected at the position of an eddy flow area of head of the combustion chamber and after the air jetting portion from the outer wall of inner cylinder of the combustion chamber.
CONSTITUTION: At first, the air 16 is introduced into the gap between an outer cylinder 1 and the inner cylinder 5 of a combustor, then, the air 10a, 11a, 12a, 13a, 14a, is introduced into a combustion chamber from the group of air leading holes which are provided at the wall surface of the inner cylinder 5, an inner cylinder cap 8 and inner cylinder cone 6. On the other hand, fuel 17 is fed to fuel injecting pipes 4a, 4b from the main body 3 of a fuel nozzle and injected into the annular combustion chamber 9 of an inner cylinder head from the nozzle 15 provided on each fuel injection pipe, then, igniting combustion is continued by the operation of a spark plug. According to this method, in the annular space forming the head combustion chamber, the fuel is injected effectively into the eddy flow and jet stream formed by the flowing air from the combustion head and annular inner cylinder side, therefore, the stable and low NOx combustion may be obtained by the combination of flame keeping under relatively lean condition and the fuel injection in the more leaned area.

CONSTITUTION:A multi-layer disc rotor 8 is assembled by coupling a plurality of discs 9. When assembling, the center shift vectors etk, ebk, face shift vectors thetatk, thetabk and unballanced residual vectors Utk, Ubk of each disc unit 9 are measured to calculate various shifts or unballance for initial angle due to virtual combination of each disc through a computor on the basis of dimension, weight, etc. If it is within allowable range, the assembling is executed with virtual combination. In such a manner, the optimal combination angle for each disc can be obtained easily within allowable range of rotor shift and unballance.

摘要： PURPOSE:To enable noise to be reduced, sufficiently maintaining wind amount in low speed, by making the pitch of a fan blade uniform on the suction side and uneven on the discharge side. CONSTITUTION:The inlet angle of a blade is gamma in each, on the basis of the position on the radius R1 of a main plate 14, but the exit angle of the blade varies from theta1 in the case of a blade 15B to theta2 in the case of a blade 15C, on the basis of the position on the radius R1 of the main plate 14 to the position on the radius R2. Thus, the exit angle is varied according to the blade as well as on nine leaves of blades. Accordingly, the discharge side pitch of the blade is not uniform, namely alpha5 between blades 15A and 15B and alpha6 between blades 15B and 15C, and so on. Thus pitch on the suction side can be made of uniform pitch beta, and the pitch on the discharge side can be made of uneven pitch alpha1-alpha11.
