A fastener comprises a housing, a socket, a pintle and a locking feature. The housing includes a shaft, a central bore that extends axially at least partially through the housing and a ball lock aperture extending from the bore. The socket extends into the housing adjacent to the first end face, and is configured such that rotation of the first socket rotates the fastener. The pintle is positioned within the bore and includes an actuation end and a rod that extends axially from the actuation end. The rod includes a ball transitioning surface and a ball locking surface. The pintle is moveable axially within the bore between a designated lock position where the ball locking surface of the pintle is aligned in register with each ball lock aperture, and a designated unlocked position where the ball lock surface of the pintle is moved axially away from each ball lock aperture.

A cutting device includes a box, a workbench disposed on the box, and a cutting assembly disposed on the box, where the workbench includes a platen for carrying a workpiece, and the platen is provided with a first cutting slot along a first direction; the platen is slidably connected to the box along the first direction, and when the platen slides towards the cutting assembly, the cutting assembly penetrates through the first cutting slot so that the cutting assembly cuts the workpiece on the platen, where a slide stroke of the platen is greater than a cutting stroke of the workpiece.

Disclosed are a substrate processing apparatus and a substrate processing method capable of improving processing uniformity of a substrate. The substrate processing apparatus includes a body configured to spin-rotate; a plurality of support pins installed on the body so as to support the substrate thereon; a plurality of chuck pins installed on the body so as to grip a side surface of the substrate; a chuck pin driver device configured to move the chuck pin from a stand-by position to a grip position when the substrate has been seated on the support pin; and a support pin spacing device configured to space the substrate and at least one of the support pins from each other while the chuck pin is gripping the substrate.

Adjustable length block assemblies are described. In an example, an adjustable length block assembly includes a block body with a tooth surface, a plate member with a tooth surface, and an adjustable block component. The tooth surfaces of the plate member and the block body are engageable to interlock the plate member with the block body. Thus, the block body is engageable with the plate member at multiple different positions to support repositioning of the adjustable length block assembly. Further, the adjustable block component is operable to control an overall length of the adjustable length block assembly to support precise adjustments to the adjustable length block assembly.

The invention relates to a device for receiving a workpiece in a bearing device for rotatably mounting the workpiece about a bearing axis (L) associated with a workpiece bearing surface. The device comprises a bearing pedestal (14) including a bearing element (1) which has two concavely cylindrical bearing surfaces (5, 6) that lie next to one another in the same bearing plane and symmetrically to a plane of symmetry containing the bearing axis (L), the cylinder radii of the cylindrical bearing surfaces being greater than the radius of the workpiece bearing surface for which the bearing device is intended, wherein the cylinder axes of the two bearing surfaces (5, 6) are parallel to the bearing axis (L) and have a distance between each other.

A fixture for holding a barrel-shaped part, including an interior surface, in a fixed position includes a body configured to fit inside the barrel-shaped part and a support ring coupled to the body. The support ring includes a peripheral channel. The fixture further includes a bladder tube engaged with the peripheral channel of the support ring and inflatable to engage the interior surface of the barrel-shaped part when the body is inside the barrel-shaped part.

A reconfigurable interface assembly includes, but is not limited to, a first sub-assembly that is adapted for attachment to a work-piece supporter. The first sub-assembly includes a first brake. The reconfigurable interface assembly further includes a second sub-assembly attached to the first sub-assembly. The second sub-assembly is adapted for attachment to a work-piece manipulator. The second sub-assembly includes a second brake. The first sub-assembly is configured to move the second sub-assembly in a first direction with respect to the first sub-assembly and the first brake is configured to inhibit movement of the second sub-assembly in the first direction with respect to the first sub-assembly. The second sub-assembly is configured to move the first sub-assembly in a second direction with respect to the second sub-assembly and the second brake is configured to inhibit movement of the first sub-assembly in the second direction with respect to the first sub-assembly.

A hydraulic cylinder includes a rod insertion hole formed in a piston member, an auxiliary rod provided to a head side end wall member and capable of being inserted into the rod insertion hole, a rod fitting hole formed to pass through the head side end wall member and the auxiliary rod, a movable rod installed in the rod fitting hole and whose end portion toward a head side end wall projects to the exterior, a movement restriction mechanism that prohibits shifting of the movable rod in an unclamping state and permits shifting of the movable rod in a clamping state.
