摘要:
A system for treating target cells with both positive and negative ions comprises a bi-polar beam delivery system configured to create and deliver both positive ion beams and negative ion beams. The bi-polar beam delivery system comprises a bi-polar accelerator configured to accelerate positive and negative ions in the same direction making such a bi-polar beam delivery system practical.

An illuminated walking assistance apparatus is disclosed. In at least one embodiment, the apparatus provides an elongated staff having a ground-engaging tip portion at a first end and a handle at an opposing second end. The staff provides a light pipe positioned proximal the tip portion and having a light-emitting member disposed therein to selectively illuminate the ground proximal the tip portion. The staff further provides a red nightlight which is always on so as to facilitate locating the apparatus in a dark environment.
摘要:
Optical membranes having embossed data on their surfaces are made by dispensing the polymer/solvent mixture onto a rotatable supporting surface bearing the embossed data, spinning the rotatable surface under conditions sufficient to form the membrane from the polymer and removing the membrane, after formation, from the rotatable surface. Such membranes can be light-transmissive, light-reflective or, as desired, partially reflective and partially transmissive.

摘要:
Edge-supported and fully supported membranes having substantially uniform thickness, and substantially parallel surfaces, and having the capacity to transmit at least about 90% of incident light with very little diffraction, dispersion or absorption of incident light are made by forming a polymer/solvent mixture, spin-coating a film of the polymer from the mixture onto a rotatable surface, which may have a release agent thereon, and, where a release agent is present, joining a frame or other support to the membrane and removing the membrane with its attached support from the surface. Apparatus for making such membranes includes a dispenser for dispensing a polymer/solvent mixture onto a rotatable support; a device for spinning the rotatable support at gradually increasing speeds from a first to a second speed; and a device for maintaining the speed of rotation of the support at the second speed until the membrane forms.

An injection-molded photomask carrier includes a base with a round opening of sufficient size and shape to permit light to pass through during a photolithographic process; at least three wall members joined to, upstanding from and framing the periphery of the base to support the edges of a photomask or a photomask/pellicle array resting on the base; a flange projecting inwardly from one of the walls, and a clip on the side of the base opposite the flange for movable engagement with the portions of the photomask or photomask/pellicle combination at its edges. A container for the carrier is complementary in size and shape to the carrier, injection-molded, and includes an injection-molded cover for the container.
