METALLIC PIPE BENDING APPARATUS, AND METHOD FOR MANUFACTURING A METALLIC PIPE HAVING A BENT PORTION
Provided is a metallic pipe bending apparatus comprising heating means for heating a working object or a metallic pipe partially into an annular shape, propelling means for propelling the metallic pipe toward the heating means, guide means including a clamp arm capable of gripping the metallic pipe and rotating on an axis of rotation, for gripping the front portion of that portion of the metallic pipe, which is heated by the heating means, by the clamp arm and for turning the gripped point on the axis of rotation as the metallic pipe is propelled by the propelling means, thereby to apply a bending moment to the metallic pipe, and compression means for applying a returning force or a force directed oppositely of the propelling direction of the metallic pipe by the propelling means, to the metallic pipe on the axis of rotation through the clamp arm, thereby to apply a compression force to the metallic pipe. The compression means is arranged so that the distance between the applied point of the returning force and the axis of rotation may be larger than the distance between the gripped point of the metallic pipe by the clamp arm and the axis of rotation. The thickness reduction can be further reduced without inviting the increase in the compression driving force in the compression bending treatment of the metallic pipe.

An organism-surrounding solenoid-type organism heater capable of producing a magnetic flux of predetermined density in a region near an affected part in a solenoid coil having a small impedance. The organism heater (10) comprises a tubular solenoid coil (17) having a size large enough to insert an organism inside the coil, a high-frequency power supply (11) for feeding power to the coil, and an organism holder (15) movably insertable into the solenoid coil (17). A half or more of the cross-sectional outline shape of the solenoid coil (17) along the circumferential direction of the outline is a circular arc, and the other part is linear. A sub-solenoid coil (21) shorter than the solenoid coil (17) and having a higher winding density than that is inserted into the solenoid coil (17). A magnetic body (40) movably insertable into the solenoid coil (17) is fitted to a movable bed (15).
There has been achieved a sludge dehydrating processor with less mechanical operation and with satisfactory dehydrating efficiency and heating efficiency. In order to process and convert sludge including an organic substance into solid fertilizer, a heating treatment zone for feeding and sterilizing an object to be treated and a dehydrating treatment/retrieving zone for separating water from the object to be treated and retrieving a treated object are provided. In the heating treatment zone, induction heating for efficiently heating the object to be treated without rotating a kiln body is introduced. In the dehydrating treatment/retrieving zone, a vortex air current producing mechanism for efficiently drying the object to be treated without rotating a dehydrating treatment chamber is introduced.
