Abstract:
PURPOSE:To prevent a conveying vehicle from laterally fluctuating by reversing a laterally moving force acting on the vehicle at one side and a lateral movement acting on the vehicle at the other side with the center line of rails as a boundary at a seamed portion. CONSTITUTION:When a conveying apparatus is started in the state that vertical wheels 45a of a conveying vehicle 15 are contacted with either one inner surface of upper and lower walls of emergency guides 13a, 13b, a controller 41 generates magnetic fluxes of the same direction as or reverse direction to a magnetic flux generated from a permanent magnet 52 at magnets 51, 52 and controls a current flowing to an exciting coil 56 to maintain a predetermined air gap between a magnetic supporting unit 31 and guide rails 12a, 12b. Since seamed portions A are formed in a symmetrical shape at two guide rails 12a, 12b when the vehicle 15 passes the seaming portions A of the rails 12a, 12b, lateral moving forces acting on the vehicle 15 act reversely on the rails 12a, 12b to be cancelled to each other out to become zero.
Abstract:
PURPOSE: To prevent the magnetic attraction force at the seam of guide rails from decreasing by connecting a plurality of split rails for forming a guide rail by joint fittings of ferromagnetic material. CONSTITUTION: A carriage 2 is movably disposed along a guide rail 1 on the rail 1. A magnetic supporting unit 3 is placed on the lower portion of the carriage 2. The rail 1 has a plurality of L-shaped sectional split rails 11 of ferromagnetic material, a supporting member 12 for supporting the rails 11 for connecting in series the rails 11, and a bolt 13 for clamping the member 12 to the rails 11. The member 12 is formed of a ferromagnetic material at the portion 14 at least contacted with the rails 11. Thus, magnetic attraction force does not varies in the seam of the guide rails.

Abstract:
PROBLEM TO BE SOLVED: To provide a contamination wiping device capable of coping with various conditions on the surface of a wiped object, while keeping pressing force of a wiping member uniform. SOLUTION: Pressing-directional force acting on a smear head 11 for attaching the wiping member, and moving-directional force of a pressing position are calculated on the basis of force measured by a hexa-axial force sensor 13, a wiping part moving mechanism 12 is controlled to bring the forces within a prescribed range, and the pressing position is changed along the surface of the wiped object 15 to wipe the surface of the wiped object 15, while pressing the smear head 11 onto the surface of the wiped object 15.

Abstract:
PROBLEM TO BE SOLVED: To provide a radiator, which is easy to manufacture and can freely set the shape, size, array and the like of a fin part. SOLUTION: A plurality of radiating fin elements 12 are structured with a pin fin part 17, by forming in parallel a plurality of slits 16 into a thin plate 15 formed with a thermally conductive material, and have a laminate 14 laminated via a spacer 13 disposed along an edge part of two sides perpendicular to the longitudinal direction of 16 slits of the thin plate 15 between the elements 12.
Abstract:
PURPOSE:To transmit power without use of an electric energy. CONSTITUTION:The operating gas is heated by heating a heater 12 of a stirling engine 1 through burning, by ignition, of a gas combustion portion 16 of a gas burner 15. Then, the operating gas is cooled by a cooler 14 disposed in the atmosphere. By expanding and contracting the operating gas through such cyclic operation, an expansion piston 5 and a compression piston 6 are reciprocatingly moved to rotate a crank 9 to thereby rotate a ventilating fan 18 connected thereto. By this, the heat energy of the gas burner 15 is effectively utilized whereby the ventilating fan 18 is automatically turned on or off according to the ignition and fire-extinguishment of the gas burner.
