A fluid pressure cylinder can apply a fastening force to an axially movable reciprocating rod. A reciprocating rodis mounted in a case main bodyso as to be reciprocable in a forward direction and a backward direction, and two lock unitsandare incorporated in the case main body, and the lock unitsandinclude: lock sleevesandmounted axially movably and having taper surfacesand; and retainersandholding steel ballsandthat are fitted in the reciprocating rodaxially movably and engaged with the taper surfaces. A fastening cylinderthat contains a fastening rod so as to be reciprocable in a fastening direction and a fastening release direction is attached to the case main body, a fastening surfacecontacting with the lock sleevesandbeing formed in the fastening rod, and the reciprocating rodis fastened by the two lock unitsand

Fluid pressure cylinder

A fluid pressure cylinder has a piston rodfixed to a pistonand projecting outside a cylinder body. A lock surfaceinclining to a radial direction of the piston rodis formed in an engagement memberprovided in the piston rod. A lock rodreciprocating in an about right-angle direction to the piston rodis built into a lock cylinderprovided in the cylinder body. The lock rodis provided with: a large-diameter sectionfitted into a guide holeformed in the lock cylinder; and a slide contact sectionprovided in the large-diameter sectionvia a constriction section. The slide contact sectioncontacts with a radial-inner portion of the lock surfacewhen the lock rodcomes nearest to the piston rod

Hydraulic cylinder

A workpiece cradle and a clamp arm is provided, and an arm opening/closing cylinderfor opening and closing the clamp arm and the workpiece cradle are attached to a moving block. To a workpiece-cradle driving cylinderprovided with a piston rodfor driving the moving block, fluid is supplied from workpiece-cradle driving supply/discharge portsandformed in a manifold block. To the moving block, guide rodsandare fixed and, to the arm opening/closing cylinder, fluid is supplied, from arm driving supply/discharge portsandformed in the manifold block, via hollow holesandin the guide rodsandand via fluid supply/discharge pathsandin the moving block

Clamping apparatus

A clamp jig has a positioning pin provided at the tip of a cylindrical member, and a clamp arm is mounted in a slit formed in this positioning pin, so as to be able to swing and so as to be able to axially advance and retreat. A reciprocating shaft is connected to the clamp arm by a connecting pin, and a spring force is applied to this reciprocating shaft in a retreating direction by a compression coil spring. A plunger brought into contact with the reciprocating shaft is mounted in a drive housing so as to be able to axially reciprocate, and a female screw member driven by a motor is thread-connected to a male screw member secured to this plunger. Accordingly, it is made possible to reliably perform positioning and clamping, of a member to be fixed, and unclamping thereof by a low-cost motor.

Positioning and clamping apparatus

In the manufacture of a single crystal film by epitaxial growth method, defects such as cracking are avoided by increasing the deviation of the lattice constant of the resulting film in the direction of growth from the substrate. Preferably, the deviation is increased at the rate of (0.4.about.9).times.10.sup.-4 %/.mu.m.

Process for producing thin film by epitaxial growth

A surgical device for stapling and fastening body tissues, comprises an insertion section extending from an operation section for insertion into a body cavity, stapling member connected to a distal end of the insertion section, for treating body tissues with a high-frequency current within a body cavity. The stapling member includes an anvil and a cartridge between which the tissues are sandwiched, and a cutter. Staples are applied to the anvil from the cartridge for stapling the tissues and the cutter cuts the tissue while it applies a high-frequency current thereto.
