摘要： PROBLEM TO BE SOLVED: To facilitate the recovery of a ruptured head by providing a holding member such as a snap ring which has the shape protruding in the direction of inner radial direction by sufficient distance for the contact of the holding member of a bit on an inner peripheral face of a wear-resistant collar. SOLUTION: A cylindrical chuck 10 is connected to a drill string casing 14 by a screw 12. A shunk 20 which is engaged in such a manner that it is driven together with the chuck 10 and is elongated in the axial direction is provided in a drill bit 13. A soft holding member 50 which protrudes in the radial direction by sufficient distance for stopping a holding shoulder 32 when the shunk 20 is ruptured and a part of a bit head 26 drops downward in the axial direction is connected to an inner face 52 of a hollow, cylindrical, and wear-resistant collar 42 in such a manner that is can be attached and detached freely between the wear-resistant collar 42 and the bit head 26. It is recommended that the hold member 50 be a snap ring. Consequently, it is possible to hold the bit head 26 in the chuck 10 even if it leaves the shunk 20. Accordingly, it is possible to recover the bit head even when the bit 3 is ruptured.

摘要： PROBLEM TO BE SOLVED: To enable seal maintenance without detaching an outlet cylindrical body from a supplying line, by providing the outlet cylindrical body having a first and a second ends, a pump base, a seat formed in the passageway wall connecting the both ends, receiving an end of a reciprocating member and having a minimum width passageway and a pump outlet and being connected with a housing base. SOLUTION: A pump outlet cylindrical body 40 is connected to a motor table 24 by a fixture 26. The pump outlet is a cylindrical body provided with first and second ends 41, 42 and an outlet port 44 provided between both ends. A passage 43 extends between both ends and is communicated with the outlet port 44. A seal member 48 is pinched between a shoulder 46 of the outlet cylindrical body 40 and a bush 34, and the inner periphery is in the passage 43 having the minimum width. A reciprocating member 18 can be moved in the passage 43. The seals 32, 48 are hermetically engaged with a movable end 22 of the reciprocating member 18, a pump 60 is screwed on the second end 42, one end of a pump pipe 62 is screwed and connected to the outlet cylindrical body 40, and the other end is screwed and connected to a foot valve 70.

摘要： PROBLEM TO BE SOLVED: To easily convert the surface shape of a drum by arranging a plurality of arcuate mounting members with a padfoot outer surface around the flat outer surface of the cylindrical type primary drum and mutually connecting the outer surface and the mounting members. SOLUTION: When the outer surface of a cylindrical primary drum 1 for a compacting machine is changed into a padfoot surface from a flat outer surface 3, a plurality of flexible arcuate mounting members 10 bent so as to be brought close to the arcuate curvature of the outer surface of the primary drum 1 are arranged onto the outer surface 3 of the primary drum 1. Adjacent mounting pads 30 installed at the connecting edges 14 of the plate members 12 of each mounting member 10 are brought into contact while being connected by fastener means 24 comprising nuts 26 and bolts 28, and the mounting members 10 are connected mutually. Accordingly, since the positions of the mounting members 10 need not be aligned with the boltholes of the primary drum 1 as seen in conventional devices, the outer surface 3 of the primary drum 1 can be converted into the padfoot surface from the flat surface.

摘要： PURPOSE: To provide a compressed air operation vibration damping shock tool capable of reducing an air consumption amount and reducing the vibration transmitted to worker's hand or arm when a tool is not applied to a workpiece. CONSTITUTION: An air restriction device which is provided with a thin tube 16 attached to a bush 17 slidably and has a ventilation hole at an end of the thin tube entering the bush 17 is provided. A series of openings provided on a wall of the thin tube 16 are sealed by the bush 17 at a position on one side of the thin tube 16 in the bush, and the openings are exposed at a position on the other side of the thin tube 16 in the bush. An air pipe passage 3 of the thin tube 16 is connected with piston assembly 12, and the thin tube 16 moves in the bush 17 in accordance with a pressure applied on a workpiece by a tool.

摘要： PURPOSE: To facilitate replacement by forming an enlarged head on a piston rod, inserting the head into a piston so as to interlock with a socket, fixing the socket so as to be released selectively by means of a releasing means which is axially moved along a piston rod. CONSTITUTION: A hydraulic plunger 4 is attached into a hole 12 in a piston 3 by means of a plunger head 8 arranged by a retainer 5 so as to be interlocked with a hydraulic cylinder 2. The hydraulic cylinder 2 is operated for completely blocking a hole 14 in which a hydraulic plunger seal 7 is arranged by means of an end cap 6. The hydraulic plunger 4 is detached from the hydraulic piston 3 by detaching the end cap 6. The hydraulic plunger 4 and the hydraulic plunger seal 7 can be replaced with new ones by providing a removable cartridge including the hydraulic plunger seal 7 and an end cap seal. the cartridge can be held in the end cap 6 by screwing between itself and the end cap 6 or bolting, flange connection, etc.

摘要： PURPOSE: To improve the service life of a nozzle by constructing a nozzle of a water jet cutter from a first material, and implanting an aggregation of ions formed from a second material onto a surface of the nozzle. CONSTITUTION: A water jet cutter 11 comprises a fluid nozzle assembly 10, and this is formed by a nozzle 12, a nozzle mount base 14 for retaining this nozzle 12, and a seal 16 for preventing the flow of fluid between the nozzle 12 and the nozzle mount base 14. On this occasion, the nozzle 12 is constructed from a first jewel material such as diamond or corundum, and a second material ion 20 such as titanium, nickel or chromium is implanted onto a surface of the first jewel material under acceleration. Whereby the molecular voids and the fine cracks in a crystalline structure of the first material are sealed, the toughness, solidity and smoothness of the nozzle 12 can be improved and the life of the nozzle 12 can be elongated.

摘要： PURPOSE: To improve a porous bed reactor for carrying out bleaching of a fibrous material such as a wood pulp with a gaseous reagent so as to completely consume the gaseous reagent without causing unevenness of the bleaching in the porous bed reactor. CONSTITUTION: The method and apparatus are to treat a fluffed fibrous material having a high consistency and comprises a mechanical mixing chamber having a dwell time sufficient that a substantial majority of a gaseous reagent is reacted before dispensing the mixture into a porous bed reactional and degasification chamber. The gas is passed through the porous bed of the fibrous material in the reactional chamber and made to flow therethrough until the gaseous reagent is substantially completely consumed. Thereby, the uniformly treated fibrous material is obtained and the reagent is efficiently utilized.

摘要： PURPOSE: To provide a handle of which grip size can be easily adjusted to match the size of the hand of a user by selectively connecting plural handle augmenters of different sizes through a connecing means to a handle base. CONSTITUTION: A pistol-shaped grip handle assembly 10 is composed of a pistol- shaped handle base 12 and a pistol-shaped handle augmenter 15. In this case, plural sorts of the handle augmenters 15 of different sizes are prepared. Connecting protrusions 13, 14 to be engaged with each other are formed on the handle base 12 and the handle augmenter 15. An augmenter fixing member 19 having a head part to be overlapped with an edge part of the handle augmenter 15 is fixed to the handle base 12. A handle of which grip size can thus be easily adjusted to match the size of the hand of a user can thus be provided.
