Abstract: PURPOSE:To make improvements in operability by drilling each stage after extracting the front stage pipe at each time in a state that respective pipes of a drilling head, constituting of a telescopic body of a third pipe equipped with both first and second bits, are contracted into one. CONSTITUTION:A plurality of suspended drilling heads setting up each axial center on a straight line are supported free of rotation and lifting motion with both rotary and feed mechanisms of a front frame being projectingly installed from a crane truck body. In this case, the drilling head is composed of a telescopic body combining an outer cylinder 11, an inner cylinder 12 and a tripple pipe rod 13 free of expansion with one another. Next, at the time of execution of works, a crane truck is moved, and a boom is uprighted and positioning of the drilling head in a state of being fully contracted is carried out. In succession, the drilling head is rotated, and pressed down to some extent, then the first hole H1 is drilled, pulling out the outer cylinder 11, and the second hole H2 is drilled. Successively the inner cylinder is pulled out, and in the state intact, the third hole H3 is drilled.

IPC: B23P19/02
Filed: 1989-05-16
Abstract: PURPOSE:To improve productivity and yield by providing external rotor supporting mechanism, internal rotor supporting mechanism, an internal rotor pivoting rod, internal rotor rotation-down mechanism and rotor exhaust mechanism. CONSTITUTION:An external rotor 1 is pivotally supported in level at a preset position by a clamp plate 30 (external rotor supporting mechanism), and an internal rotor 2 is supported in level at the upper part of the rotor 1 by internal rotor supporting mechanism 52, with the eccentricity from the rotor 1 as much as the eccentricity when assembled. An internal rotor pivoting rod 100 is raised through the rotor 1 by internal rotor rotation-down mechanism to put and fix the rotor 2 on the upper end of the rod 100. The support by the supporting mechanism 52 is released, and the rod 100 is being rotated at a low speed and lowered to put the rotated rotor 2 in contact with the upper face of the rotor 1. The rotor 2 is thus promptly dropped by its weight in the rotor 1 at the moment of the coincidence of a relative angle. Then, the rod 100 is further lowered to cause the rotor 2 to be engaged with the engaged portion of the clamp plate 30 and left in the rotor 1.

Abstract: PROBLEM TO BE SOLVED: To prevent mutual fusion of the inner top face and the aluminum foil of the upper face of a seal member in a hermetically sealed condition, by forming a ring-form recessed part provided with a specified level difference, which is larger than the diameter of a container opening at the inner top face. SOLUTION: A seal member in which synthetic resin films 4 are laminated is put at the under face of an aluminum foil 3 having a lug 2 at a part of the periphery, and a cap 6 is put thereon to screwed on the container opening 1. In this way, the peripheral end of the seal member is folded at the external end of the container opening 1 to closely contact the upper end of the side face. A ring-form recessed part 7 is formed at the inner top face to secure a gap forming an air layer between the upper face of the seal member 5 and the underface of the recessed part 7. In this case, the level difference of the recessed part 7 is made about 0.05-1 mm. In this state, the aluminum foil 3 is treated by high frequency heating to weld the synthetic resin film 4 on the container opening 1. In this time, the fusion of the inner top face and the seal member is prevented because of the gap.
