摘要： PURPOSE: To provide a bending method of a double pipe by which energy consumption is suppressed to the absolute min., cycle time is shortened and a charged material is surely discharged. CONSTITUTION: This method is composed of a process in which the charging material consisting of plural bar-shaped rectilinear wires 6 is charged into the space of the hollow double pipe 4 along the longitudinal direction of the space 9, process in which the hollow double pipe 4 is bent and process in which the rectilinear wires 6 are pulled out of the bended hollow double pipe 4. Since the rectilinear wires 6 are used as the charging material, heating and cooling processes are unnecessitated as compared to the case that the charging material is water (ice), large energy consumption for heating and cooling is omitted and also the cycle time is shortened. As compared to the case that the charging material is sand or a steel ball, the generation and scattering of dust is not brought about. Further, as compared to that the charging material is wax, heating at the time of charging and discharging the charging material is unnecessitated, so energy consumption is reduced as much and the cycle time is shortened.

摘要： PROBLEM TO BE SOLVED: To produce a preform formed body into which Mg or Mh alloy molten metal is easily infiltrated by dropping a soln. in which reinforcing material powder and infiltrating assistant material powder are dispersed into a preform die, thereafter heating the dispersion soln. and drying it. SOLUTION: Af first, a reinforcing material of ceramic particles not reacted with Mg such as Sin, an infiltrating assistant material such as SiO2 and an organic binder are charged to the inside of a solvent such as water, and stirring is executed to uniformly disperse them. In the case this dispersion soln. 6 is poured into a preform die 7, and filtering is executed, though it depends on the kinds of the reinforcing material and infiltrating assistant material or the like, a peform contg. about 15 to 50vol.% reinforcing material can be formed. In this case, when the reinforcing material and infiltrating assistant material having different precipitating rates in the solvent are used, a concn. gradient can be given to the infiltrating assistant material in the preform formed body, and the infiltrating phenomenon can smoothly be progressed. Then, the preform formed body is heated at the b.p. of the solvent or below and is dried.

摘要： PURPOSE:To control the amt. of the strengthening particles to be added by mixing the strengthening particles with a cooling medium and injecting a mixture to the molten metal released from a nozzle, thereby making the molten metal finer. CONSTITUTION:The molten Al alloy 3 in a tundish 4 is released from the nozzle 5 into an injection chamber 2. The strengthening particles 10, such as ceramics particles in a vessel 9 are released into pipings 6 of the cooling medium 7, such as high-pressure gas and the cooling medium 7 mixed with the strengthening particles 10 is injected through nozzles 8 into the injection chamber 2. The molten Al alloy 3 is thus pulverized to the fine powder by the cooling medium mixed with the strengthening particles 10. The temp. of the strengthening particles 10 is raised by using a heater 12. As a result, the uniform dispersion of the strengthening particles is possible even if the strengthening particle diameter is small and even if the amt. of the particles to be added is large.

摘要： PROBLEM TO BE SOLVED: To provide a tube manufacturing method by which the discharge time of a filler is shortened. SOLUTION: The hollow double bent tube 1A in which solidified molten salt 7 is charged is immersed into the molten salt 7 in a liquid state in a salt bath 12. The heat of the molten salt 7 in the salt bath 12 is rapidly transferred to the solidified molten salt 7 in the hollow double bent tube 1A and this solidified molten salt 7 is quickly liquefied. Then, the molten salt 1 is discharged from the hollow double bent tube 1A in a short time. As compared with a hot-air circulating type discharging furnace used in a conventional technique, heat transfer region is reduced, the loss of energy is proportionally decreased and energy conservation is contrived. Furthermore, because it is enough to prepare the salt bath 12 and to store the liquid molten salt 7 in the salt bath 12, as compared with the hot-air circulating type discharging furnace which is used in the conventional technique, the device is simplified, therefore space saving and reduction of the cost of equipment are contrived.

摘要： PROBLEM TO BE SOLVED: To obtain a bending method for a hollow double tube by which the energy consumption is reduced to a minimum and a cycle time is made short. SOLUTION: A method consists of a process to insert a cylindrical bag body 7 having the flexibility and pressure resistance into a gap 3 of a hollow double tube 1, a process to press-inject a fluid 8 into the bag body 7 and a process to apply bending stress to the hollow double tube 1 while the fluid 8 is press- injected in the bag body 7 so as to bend the hollow double tube 1. Because of the use of the bag body 7 and the fluid 8 press-injected in the body bag 7 as the packing material, the heating/cooling process is not required as compared to water (ice) as the packing material and the energy consumption for heating/cooling is eliminated and a cycle time is shortened. Further, the generation of the dust and spattering are not incurred as compared to the packing material of the sand or steel ball. Further, the fluid 8 as the packing material has no deterioration accompanying the use, the continuous use is made possible to reduce the cost in this respect.

摘要： PURPOSE:To easily perform overall measurement on the shape of keyways in hole sections of works and chamfered states of tips on a working line. CONSTITUTION:The chamfered state and suitability of chamfered amount of a work 1 are detected by means of a chamfer detecting means 35 from the position of chamfer inspecting jigs 38 and 62 by putting the jigs 38 and 62 on the work 1, with the chamfer detecting surfaces of the jigs 38 and 62 being faced to the chamfered part of the work 1 and a keyway in the hole section 2 of the work 1 is detected by putting the keyway detecting surface of a probe 80 which is forcibly pushed toward the internal surface of the hole section 2 in a freely swingable state on the keyway. While the front end of the probe 80 is brought into contact with the internal surface of the hole section 2, the position of the probe 80 in the radial direction of the work 1 is measured with a measuring means 81 and, by rotating the probe 80 by means of a rotating means 82 while the probe 80 is forcibly pushed toward the internal surface of the work 1, the chipped tooth section of the spline tooth of the work 1 is detected by inserting the chipped tooth detecting projection at the front end of the probe 80 into the chipped tooth section. The front end of the probe 80 is removed from the internal surface of the hole section 2 by means of a removing means 83 at the time of setting and removing the work 1.
