A clamper (23) includes a clamp mechanism (231) which inserts an insertion portion (2311a) into a tube member and clamps the tube member and a lifting and lowering mechanism (232) which lifts and lowers the clamp mechanism (231) in the insertion direction of the insertion portion (2311a). The clamp mechanism (231) includes a clamp body (2311) which has the insertion portion (2311a), a cotter (2312) which protrudes from the insertion portion (2311a) to come into friction-contact with the tube member and is movable in a reciprocating manner in the insertion direction of the insertion portion (2311a), a piston rod (2313) which presses the cotter (2312) so that the cotter protrudes from the insertion portion (2311a) when being pulled toward the opposite side to the insertion direction of the insertion portion (2311a), and a rod cylinder (2315) which is integrated with the clamp body (2311) and pulls the piston rod (2313).

To correspond to a shape of a shot-peening worked portion and to prevent a situation where shot media scatter around the worked portion. To achieve this object, a shot peening apparatus for hitting shot media B against a welded part W and for applying a compressive stress to the welded part includes a kinetic-energy applying unit 26 that applies kinetic energy to the shot media B by an oscillator 26b, and a surrounding unit that surrounds both a worked portion U including the welded part W and surroundings of the oscillator 26b, and that confines the shot media B within the surrounded region while changing a state to correspond to a shape of the worked portion U.

There is provided a device for bonding ceramic structural bodies. In the state in which a set of ceramic structural bodies provided with a bonding agent between bonding surfaces and provided with elastic sleeves disposed on a peripheral surface of the set of the structural bodies are placed in a tubular container with an elastic sheet disposed between the elastic sleeves and the tubular container, the device is able to charge a hydrostatic pressure medium between the tubular container and the elastic sheet to press and bond the structural bodies. By bonding the ceramic structural bodies with the device, it may provide accurate positioning of the bonding surfaces. It may also provide a uniform distance between bonded surfaces, and reduce the number of bonding operations, thereby affording an excellent working efficiency.

摘要:
A signal processing device processes a position information signal (A sinθ, A cosθ) output from a sensor in accordance with a driving position of a motor and detects a driving speed of the motor. The signal processing device includes a position information signal processor (410) that processes the position information signal and calculates driving speed information of the motor, and an internal position information generator (460) that reflects a latest driving speed information (ωn) calculated by the position information signal processor (410) and generates a latest presumed position of the motor as internal position information. The position information signal processor (410) calculates driving speed information (ωn) of the motor based on a difference between the position information signal (A sinθ, A cosθ) from the sensor and the internal position information (A sinθn, A cosθn) generated by the internal position information generator (460).

There is disclosed a sealing material for sealing a ceramic structure, the sealing material containing a ceramic component, an ordinary-temperature liquid component, and a suspending agent. In a method in which opening end portions of a large number of through channels 3 divided by partition walls 2 and extending in an axial direction in a honeycomb structure 1 including the through channels, the method comprises the steps of: sealing the opening end portions using the above-described sealing material. Sealed portions 10 are formed in the opening end portions of the through channels 3 by the sealing material. There are disclosed a sealing material, a sealing method for a honeycomb structure, and a sealed honeycomb structure in which less kinks are generated in the sealed portions, and a depth in each sealed portion fluctuates little.

A method of bonding at least a first ceramics structure (101) to a second ceramics structure (102), which includes the steps of applying a pressure to the first ceramics structure (101) and the second ceramics structure (102) in such a direction that these structures move close to each other with a bonding material layer (110) interposed between the first ceramics structure (101) and the second ceramics structure (102) (FIG. A), removing a bonding material (111a) extruded from the bonding material layer (110) to an end face of a stacked body including the first ceramics structure (101) and the second ceramics structure (102) by the application of the pressure thereto (FIG. B), drying a bonding material (111b) near the end face of the stacked body (120) after the extruded bonding material (111a) is removed (FIG. C), and drying the entire part of the stacked body (120).

There is provided a honeycomb structure 1 produced by bonding a plurality of honeycomb segments 12 into one piece via a bonding layer 8, each segment 12 having a number of through-holes 3 divided from each other by porous partition walls 2 and extending in the axial direction of the honeycomb segment. The bonding layer 8 comprises at least one cement layer 10 and at least one undercoat layer 9 present between the honeycomb segment 12 and the cement layer 10. There is provided a process for producing a honeycomb structure 1, wherein bonding the honeycomb segments 12 comprises applying at least one layer of an undercoat on each honeycomb segment 12, applying at least one layer of a cement, and bonding the honeycomb segments into one piece. The honeycomb structure has a high bonding strength and hardly gives defects such as cracks in bonded portion.
摘要:
The servo control method operates a set value of a first-order lag time constant of a feedback compensation by both a detected mechanical position value and a transfer function corresponding to a change of an angular velocity about each axis under a multiple-axes simultaneous control. Further, the servo control method sets a feedforward amount so that the transfer function about the each axis is the same.
