摘要： PROBLEM TO BE SOLVED: To safely remove and adapter in a short time, and fill a joint material in a hole cut in an object to be repaired. SOLUTION: A hole is cut in an object to be repaired, and a plug 10 for pouring the fluid is inserted therein, and a rubber packing 14 is pressed against an internal wall of the hole, and tightly fixed thereto, and the fluid is poured therein. The packing 14 is pressed outward by relatively moving at least a part of an expanding member 12 to be arranged inside the packing 14 outwardly in the axial direction of the hole to the packing 14, and tightly fixed thereto. The plug 10 for pouring the fluid is left in the hole in a condition that the plug is tightly fixed to the internal wall of the hole, and a joint material 38 is filled in the hole to complete the work.

摘要： PROBLEM TO BE SOLVED: To improve fusion strength at a low temp. and in a short time by heating a gas which emits far infrared rays in a region of wave lengths with relatively high absorbance at a temp. where a large quantity of far infrared rays are emitted and blowing it on both end parts of adjoining members. SOLUTION: A gas fusion apparatus 10 is provided with a heater 30 which can heat a gas to a temp. where a large quantity of far infrared rays with specified wave lengths can be emitted on a quartz glass surrounding body. Carbon dioxide emits a large quantity of far infrared rays when it is heated e.g., at 550 deg.C On the other hand, absorption spectra of PTFE being a material for pipe members P and P exhibit high absorbance in a region of far infrared rays. The quartz glass absorbs far infrared rays and passes them through it while they are wholly reflected inside and when there exists an end face 24a being approximately square to the wall face, they are emitted concentratedly therefrom. When the far infrared rays emitted from carbon dioxide are concentratedly emitted from the end face 24a, vicinity of fusion end face is heated with these far infrared rays to improve furthermore heating efficiency.

摘要： PROBLEM TO BE SOLVED: To melt the end surface of a resin-made tubular part in a short time and at low temparature, thereby reduce energy consumption quantity needed for melting. SOLUTION: This heater device is used when a pair of resin-made pipes (2 and 4) to be connected are faced with each other, the facing end surfaces of the pipes are heated and melted respectively, and then both the resin-made pipes are relatively neared to be welded. Also, this device is provided with radiators (10e and 10f) composed of; a material capable of radiating, at high emissivity, far infrared rays including a wavelength region, having a relatively high absorption coefficient in an absorption spectrum of the resin-made pipes to be connected; and a heating element (10a) for heating the radiators to radiate given far infrared rays. In a preferable example, the resin-made pipes are composed of fluor-resin such as PTFE, FET, PFA, ETFE, CTFE, and PVDF, etc., or a high grade engineering plastic-made pipe, and the radiator is composed of a ceramic-made thin layer.

摘要： PURPOSE: To easily constitute an eccentric shaft structure having suitable strength, by fixedly inserting a thin plate member of drilling a hole of shape compensated each other to a sectional shape of a shaft, in an eccentric position of a shaft having a specific sectional shape except a circle. CONSTITUTION: A crankshaft 16 used in a pump or the like is provided with a bar member 16a of equilateral hexagonal section, plurality of disks 16c fixed with a 120 deg. space in a direction of rotation with the bar member 16a serving as the center and a ring member 16e mounted rotating in each disk 16c through a rotational bearing 16d. Each disk 16c has a hole 16b, having a section of equilateral hexagonal shape similar to a section of the bar member 16a, in the same eccentric position. The bar member 16a is inserted to this hole 16b, to fix each disk 16c to the bar member 16a. Thus by only inserting each disk 16c with a protruding direction changed to the bar member 16a, a plurality of the disks 16c can be easily fixed with a 120 deg. space in a direction of rotation with the bar member 16a serving as the center relating to the bar member 16a, to reduce a cost further to be made easily manufacturable.

摘要： PURPOSE: To smoothly finish the inner surface of a pipe welded part by making the width of a welding auxiliary member larger than the sum value of the melting depths of a pair of plastic tubular members to be welded and making the length thereof larger than the inner peripheral length of the plastic tubular members. CONSTITUTION: The width of a welding auxiliary member 10 is made larger than the sum value of the melting depths of a pair of pipes 20 to be welded. When the pipes 20 are formed from fluororesin since the melting depth of each of the pipes is about 2-5mm usually, the width of the welding auxiliary member 10 in this case must be at least about 6-12mm. The length of the welding auxiliary member 10 is made larger than the inner peripheral length of the pipes 20. When the welding auxiliary member 10 is thick and high in bending rigidity, the length thereof is as sufficient as about 1.2 times the inner peripheral length of the pipes 20.

摘要： PURPOSE: To enable thermal welding of a thermally weldable resin-made tubular part to be carried out without requiring skillfulness by a method wherein a cutting part, an abutting part, and a fusing part are arranged at specific intervals in a rotary direction to a rotary disk driven by dividing, and one side tubular part is brought relatively close to the other side one fused by the fusing part to be welded thereto. CONSTITUTION: A pair of tubular parts 12, 12a are set to tubular part receiving parts 16, 17. An abutting part 24 arranged to a rotary disk 30 knocks respective end faces against each other so as to become plane surfaces in a direction normal to an axis, and clamping parts 10, 11 clamp appropriately them. Then, a cutting part 26 chamfers an end face of the tubular part 12a clamped by the clamping part 11, and chamfers an end face of the tubular part 12 clamped by the clamping part 10. Then, a support arm 14b is moved to make intervals to the clamping parts 10, 11 specified lengths. After preheating by a preheating heater of a fusing part 36, the fusing part 36 is inserted between a pair of the tubular parts 12, 12a by a linear transfer mechanism, and heated for a specified time. Thereafter, the tubular part 12a is moved to the tubular part 12 side to weld the tubular parts 12, 12a to each other.

摘要： PURPOSE:To permit the light operation by one hand by pushing out the grease in a plunger chamber when the plunger is pushed in, by gripping a lever, and sucking grease by the decompressed pressure in the plunger chamber in the case where the lever is returned to an original position by the springy force. CONSTITUTION:In use, the mouth part of a disposable type grease cartridge 22 is fixed through the driving into a tube connection port 14c. Then, an operator grips a lever 20 by attaching an outer cylinder 12 onto a palm by one hand, and then a plunger 14b is moved leftward, pushed by the lever 20. Accordingly, the inside of a cylinder chamber 14a is sealed, except in an oil passage 14e, and the grease inside the cylinder chamber 14a is pushed out to an oil pouring mouthpiece 16 through the oil passage 14e by the succeeding leftward traveling of the plunger 14b. When the operator releases the force of the hand, the lever 20 is moved rightward by a spring 24, and the grease in the bellow shaped cartridge 22 is sucked into the cylinder chamber 14a in a decompressed state.
