A single-acting, full return clamp (10) holds first and second objects, such as mold portions, in a compressive clamping relationship. A body (12), for attachment to the first object, has a housing (22) with first and second end plates (16, 18). A shaft (26) moves axially in the body and rotates about an axis of the body. A shaft end (32) outside of the housing bears against the second object in a first condition and disengages from the second object in a second condition, where the shaft end is lifts away from the body, and rotates relative to the axis. A spring (40) in the housing applies compressive force on the shaft in the first condition. A piston (74), in the housing near the first end plate when the device is in the first condition, moves axially against the spring force to move the shaft while in the second condition.

The device relates to a device for producing plastic bodies wherein the device comprises a photopolymer curing unit comprising at least one radiation source with a selected radiation spectrum or spectrums for curing of light hardening photopolymer, a mold which mold is partially or wholly comprised of light transmissive material which material allows the passage of radiation of selected spectrum or spectrums for curing of light hardening photopolymers, and a fixture for securing and rotating the mold along one or more axis.

Light hardening photopolymer is introduced into the cavity of the mold and exposed to a selected radiation spectrum or spectrums for curing of light hardening photopolymers through the mold light transmissive material thereby hardening and curing the light hardening photopolymer whereupon the cured light hardening photopolymer is removed from the mold and the process repeated.

The device permits the production of photopolymer molded bodies or photopolymer coated bodies in a continuous or discontinuous process.

Provided is a transdermal absorption sheet capable of improving strength against impact at the time of puncture. A transdermal absorption sheet includes a sheet portion and a plurality of needle-like protruding portions arranged on a first principal surface of the sheet portion, in which the sheet portion has a center portion which is a region in which the plurality of needle-like protruding portions are formed, and an outer edge portion which is a region from the center portion to an end portion, and a maximum thickness of a thickness portion of the outer edge portion is larger than an average thickness of the center portion.

A method of and fixture for molding a product with an embedded ring. A system for molding a ring into a product including a rotational molding mold with an opening formed in the rotational molding mold sized to fit a ring. A fixture is removably couplable to the ring, wherein the ring and the fixture when coupled are removably couplable in the opening. The fixture is removed from the ring after the ring is molded into a product. A method of manufacturing a product with an embedded ring includes: coupling a ring to a fixture; clamping the fixture and the ring in an opening in a mold top; clamping the mold top to a mold bottom; rotomolding a product; unclamping the fixture from the mold top; uncoupling the fixture from the ring; unclamping the mold top and the mold bottom; and removing the product from the mold.

A touch substrate includes a base substrate, a common electrode and a wire electrode. The base substrate has a plurality of common electrode areas. A common electrode is disposed in each of the common electrode areas. The common electrode has a plurality of first electrode lines extended in a first direction and arranged in a second direction crossing the first direction and a plurality of second electrode lines arranged in the first direction. The wire electrode is connected to an end of the common electrode to apply a voltage to the common electrode. The common electrode and the wire electrode are simultaneously formed through a same process using a printing substrate.
