Projections 22 of the blade 16 provided on a blade surface in a wafer-loading region 18b of a body 18 support a wafer W loaded on the blade surface 18a. Since the projections 22 have microgrooves formed by surface roughening the wafer W is retained on the projections 22 with a suppressed displacement. The blade 16 has a simple structure that retains the wafer W without vacuum suction and has no receiving hole to retain the wafer W in the body 18 of the blade 16. This can effectively prevent formation of defects on the wafer W.

An omni-positional hoist ring assembly including a bushing element that includes a sleeve with an axial length, a proximal end and a distal end. A load bearing flange is radially disposed about the proximal end of the sleeve. The sleeve has an internal thread extending at least part way of the axial length of the sleeve. A mounting screw element has a major axis, a head, and a shank disposed generally co-axially around the major axis. The shank includes a threaded shank portion and a bearing portion. The bearing portion is a generally cylindrical axially extending portion of the shank that has a diameter approximately equal to the minor diameter of the thread in the threaded shank portion. A thrust washer element is provided between the head and the distal end of the sleeve. A body element receives the in-turned opposed ends of the legs of a lifting loop element in sockets. The lifting loop is free to pivot. The body element is free to rotate about the sleeve, so the lifting loop will self align with a load that is applied to it from any direction within a hemisphere centered on the major axis of the mounting screw element. The elements of the hoist rig assembly are assembled by aligning them and inserting the mounting screw element into the sleeve and threadably advancing it until the bearing is aligned with the internal thread so further rotation of the mounting screw element does not threadably advance the mounting screw element relative to the sleeve.

A device for gripping, holding, and releasing objects of varying sizes and shapes, which comprises an elongated torus (30) enclosing a fluid material (31), an external control rod (40), and an internal control rod (38). Torus (30) may be made of a flexible membrane and able to seal in fluid material (31). Fluid material (31) can be a gas, liquid, solid particles, semisolid particles, or mixtures of these. Central channel (34) of torus (30) is collapsed due to pressure of fluid material (31) within torus (30). Both control rods are securely attached to torus (30), with rod (38) attached to the interior portion of the torus along collapsed central channel (34), and rod (40) attached to the exterior portion of the torus on outer surface (32). Gripping action is achieved by differential linear motion of control rods (38) and (40) along the longitudinal (elongated) axis of torus (30). This causes front portion (36) of the torus to slide radially inward or outward to grip objects. Further movement of the control rods can cause the object to be pulled completely inside the collapsed channel for secure gripping by completely surrounding the object. The soft flexible nature of torus (30) allows grasping even the most delicate objects without damaging them. Even over-ripe strawberries can be rapidly grasped without bruising.

An article for mounting from or against the ceiling is removably coupled to a base fixedly secured to the ceiling, by a person standing on the floor, supporting the article on an elongated rod, and thrusting the article against the base to couple the article and the secured base. The article is removed by inserting the rod into the article, exerting a force on the rod to uncouple the article from the base, and supporting the article on the rod as the article is lowered. The article is thus positioned on or hung from the ceiling, without being manually contacted by the person. The article may be used to mount other devices, such as a sign, smoke detector, etc. or may include such device as a part of the mount.

A bio-inspired device is provided designed to scale smooth vertical surfaces using anisotropic frictional materials. The device draws its inspiration from geckos and other climbing lizards and employs similar compliance and force control strategies to climb (or hang onto) smooth vertical surfaces including glass, tile and plastic panels. Foremost among the design features embodied in the device are multiple levels of compliance, at length scales ranging from centimeters to micrometers, to allow the device to conform to surfaces and maintain large real areas of contact so that adhesive forces can support it. Structures within the feet ensure even stress distributions over each toe and facilitate engagement and disengagement of the adhesive materials. A force control strategy works in conjunction with the anisotropic adhesive materials to obtain sufficient levels of friction and adhesion for climbing with low attachment and detachment forces.
