摘要： PURPOSE:To generate a pulselike exciting force in only one direction vertical to the shaft of a thin type by mounting eccentric loads in the same amount with the phase shift of 180 deg. on both shafts of a tandem-compounded motor and making a opposite rotation for both shafts each other. CONSTITUTION:An eccentric weight 7a is mounted on a rotary shaft 6 in one side, and the rotary shaft in another side is connected with a concentric gear device 9 which output shaft 8 is made to rotate oppositely to the shaft 6 with the equal speed, and another eccentric weight 7b in the same amount is mounted on the output shaft 8 at a position with the 180 deg. phase shift from the eccentric weight 7a. When the eccentric weights 7a, 7b are placed on a position (a), centrifugal forces Pa, Pb to an axis X-X are offset because the directions are opposite each other, then the exciting force is made to be zero. When the eccentric weights 7a, 7b are placed on a position (b), the directions of the centrifugal forces Pa, Pb are the same and the exciting force corresponding to Pa + Pb is effected to the axis X-X. With this arrangement, the pulselike exciting force can be generated in only one direction intersecting orthogonally with the shaft of the thin tube.

摘要： PURPOSE:To increase the property of safety against earthquake by a method wherein a tube support plate is provided across the straight led sections of a multitude U-shape heat transfer tubes and the outer end of vibration preventing rod, provided between neighboring U-shape sections of heat transfer tubes, is fitted loosely to a connecting member located at the outside of the U-shape sections. CONSTITUTION:The bundle of heat transfer tubes is constituted of the groups of a multitude of U-shape heat transfer tubes 21, arranged in the same plane, having different radii of curvatures of bending and arranged in parallel with spaces between each others. In this shell and tube type heat exchanger, the tube support plate 22 is provided across the straight leg sections of the heat transfer tubes 21 while the vibration preventing rods 23, located at the U-shape section of heat transfer tube 21, are arranged between neighboring heat transfer tube groups. The outer end of the vibration preventing rod is fitted loosely to a connecting member 24 located at the outside of the U-sections of the heat transfer tubes 21 and either one of the rod 23 or the member 24 is fixed to the outer shell of the heat exchanger. As a result, the vibration of whole of the heat transfer tubes in case an excessive vibrating force is effected is restricted, the safety of the heat transfer tubes may be secured and prominent earthquake-proof performance may be obtained.

摘要： PURPOSE:To permit vibration of a thin tube in a position where it could not be excited heretofore, by an apparatus wherein guide plates at the distal end of a flexible tube are inserted into a thin tube, and a ball is shot out through a guide groove. CONSTITUTION:A direction converting section 1 of a thin-tube vibrator has such a construction that guide plates 10, 11 mounted rotatably about the axis are fixed to the distal end of a flexible tube 2 by screws 3, 4. The direction converting section 1 is smoothly rotatable about a bearing 9 fixed to the distal end of the tube 2 and, at the same time, it is jointed by fitting the projected part of the direction converting section 1 with the recessed part of the bearing 9. Compressed air 7 is now abruptly introduced to blow away a steel ball 5, so that the ball passes through the tube 2 and the guide groove 6 and then strikes against the inner wall of the thin tube, thereby to vibrate it. By so doing, it becomes possible to vibrate thin tubes even in heat exchangers or the like for tapping test, which tubes are in positions where they could not be vibrated heretofore.

摘要： PURPOSE:To detect a pipe having possibility of corrosive damage even during a use period, by measuring the damage sensitivity of a heat transfer pipe by measuring the magnetic characteristics of the heat transfer pipe by a ferrite scope or a magnetic balance. CONSTITUTION:For example, a high nickel pipe within the standard component range of JIS Standard NCF 600 TB is used and a pipe having received corrosive damage by the addition of a minute amount of caustic soda is measured. Susceptibility is measured with respect to the pipe of which the corrosion was confirmed (damaged pipe) and a pipe of which the corrosion was not confirmed (healthy pipe). The susceptibility of the damaged pipe is low but that of the healthy pipe is high and difference is clearly confirmed between both pipes. Similarly, even if ferrite scope intensity is measured by a ferrite scope, difference is clearly shown between the damaged pipe and the healthy pipe. Because magnetic characteristics are measured, a heat transfer pipe having damage sensitivity can be detected and a pipe having possibility of the generation of corrosive damage can be replaced by periodic inspection.

摘要： PURPOSE:To obtain a highly viscous fluid which can be suitably used at a high temperature and in an atmosphere exposed to radiation in a vibration proof damper for vibration proof type nuclear energy heat exchanger by utilizing a silicone oil of methyl phenyl polysiloxane. CONSTITUTION:A vibration proof damper absorbs vibration by viscosity of a fluid 3 in a container 1 when a heat exchanger 4 connected to an inner cylinder 2 is vibrated due to causes such as an earthquake. Silicone oil of methyl phenyl polysiloxane is used as the fluid 3. This type of silicone oil has low viscosity at room temperature, low temperature dependence of the viscosity, and excellent viscosity stability when exposed to radiation. Furthermore, it shows long durability against gas generation and fluid decomposition in the actual temperature range.

摘要： PURPOSE:To easily provide high resistance to damage by corrosion to a heat exchanger tube made of a high-Ni austenitic alloy by heating the damageable part of the tube under prescribed conditions. CONSTITUTION:The damageable part of a heat exchanger tube made of a high-Ni austenitic alloy and having sensitivity to damage by corrosion is heated at 650-750 deg.C for >=1min. This heating is carried out under such conditions as to give >=0.09% ferrite scope intensity at ordinary temp. When the concn. of Cr in the alloy is locally lowered by the precipitation of chromium carbide, the Cr-deficient part is changed into a ferromagnetic body. Ferrite scope intensity shows the extent of the change.

摘要： PURPOSE:To excite a thin tube at a position where no thin tube can conventionally be excited, by attaching a spherical guide ball to the end of a torque wire, and providing the torque wire with a plurality of eccentric weights each supported at both sides thereof by guide plates. CONSTITUTION:A thin-tube exciting apparatus has a spherical guide ball 2 attached to the end of a flexible torque wire 1, which has a plurality of eccentric weight parts 5 each provided with an eccentric weight 4 supported at both sides thereof by guide plates 3. The eccentric-weight parts 5 are rotated by a motor 8 through the torque wire 1 protected by a guide tube 10 from the end part of a thin tube 6. As a result, the thin tube is forcedly excited by the rotation of the eccentric weights, thereby allowing a tapping test. By inserting the apparatus of the invention into a thin tube of a heat exchanger, to be subjected to a tapping test, at any position, it is possible to excite a thin tube at a position where no thin tube can conventionally be excited.
