A pair of preferably substantially buoyant-in-water hand pliers comprising a pair of non-metallic lever members each having a handle portion and a jaw portion and formed of material preferably having a density greater than water. The lever members are pivotally connected together at common central portions between the jaw and handle portions. Each handle portion preferably has one or more outwardly opening cavities formed into a side surface of the handle portions. An elongated tubular sheath preferably formed of material buoyant in water covers and sealingly encloses the cavities whereby the effective density of the pliers is less than that of water. An effective, durable, non-corrosive wire cutting arrangement is also provided, the components uniquely configured and supported in the non-metallic jaw portions.

An edge-lit panel features extractor patterns that produce uniform illumination. The effective density of extractor pattern pixels is adjusted to achieve uniform illumination. A method of adjusting the effective pixel density of extractor pattern pixels to achieve uniform illumination entails adjusting areas of darkness of a grayscale image, then producing a binary image by dithering the grayscale image, and applying an extractor pattern corresponding to the binary image to a surface of the panel. The extractor pixels correspond to pixels of the binary image derived from a dithered grayscale image, with the darkness of the grayscale image increasing with distance from the light source. Effective pixel density is increased to compensate for attenuated output in dim areas. By adjusting gray shading darkness of a grayscale image, pixel density can be adjusted to achieve uniform light emission. The extractor pixels may be applied using a radiation curable ink, which can be used in high speed inkjet printers that can achieve production speeds. The resulting print is waterproof, embossed and vibrant.

A pair of composite material substantially buoyant-in-water hand pliers including a pair of elongated metallic lever members each having a handle portion and a jaw portion and formed of higher rigidity metallic material having a density greater than water. The lever members are pivotally connected together at common central portions between the jaw and handle portions. Each handle portion is substantially encapsulated by an elongated molded-in-place contoured grip formed of material buoyant in water wherein the effective density of the pliers is in very close proximity to that of water. Uniquely configured jaw inserts are also provided.

The present invention comprises a plurality of injectable hollow particulate fillers suspended in a biocompatible fluid carrier to significantly improve the clumping resistance and injectability of the composition. The hollow particulate fillers have a lower effective density and are able to suspend in the carrier without precipitation. The loss of skin volume as a result of aging, diseases, weight loss, and injury can lead to uneven skin surface (e.g. wrinkle, etc.). The uneven skin can be repaired by injecting appropriate amount of hollow fillers underneath the skin. Some cases of urinary incontinence occur when the resistance to urine flow has decreased excessively. Continence is restored by injecting the present invention to the urethra tissue to increase resistance to urine outflow. Similarly, the present invention allows for the control of gastric fluid reflux by submucosal injections of the fillers to the esophageal-gastric and gastric-pyloric junction. For patients with vesicoureteral reflux, it can be treated by injection of the present invention into patients' ureteral tissue. This invention can also be used to repair defective or inadequately functioning muscles of the anal sphincter by administering an effective amount of injectable hollow fillers into the defect or anal sinuses.

The present invention relates to a method for fabricating semiconductor device with negative differential conductance or transconductance. According to the present invention, a fabrication process thereof can be simplified by using an SOI (Silicon-On-Insulator) substrate, and a tunneling device exhibiting the negative differential conductance or transconductance at room temperature can be implemented by using P+-N+ junction barriers as tunneling barriers and implanting impurity ions into a channel region so that their density is higher than the effective density of states where electrons or holes can exist thereon. Since the semiconductor device with the negative differential conductance or transconductance can be also be implemented even at room temperature, there is an advantage in that the present invention can be applied to an SRAM or a logic device using a device which can be turned on / off in response to a specific voltage.Further, according to the fabrication method of the present invention. miniaturization of the device can be easily made, and the reproducibility and the mass productivity of the process can be enhanced. Simultaneously, the gate, the source / drain and the channel regions are formed by the self-aligned process. Thus, there is another advantage in that a gate pitch can also be reduced.In addition, there is a further advantage in that the semiconductor device fabricated according to the present invention has the characteristic of a single electron transistor by using the channel region as the quantum dot and the two P+-N+ junctions as the tunneling barriers.

A shot pellet that, has an inner core of a material such tungsten carbide, that is coated with a layer of bismuth. This coating is molecularly bonded to the tungsten carbide and is not an alloy. The unique properties of the shot pellet allow its density to be tailored. Under this process, the effective density of the pellet can be made to be identical to lead for direct replacement in current lead loading formulations. Additionally, the density can be made to be lower than lead for shotguns requiring low barrel pressures, or higher than lead for enhanced energy transfer while maintaining the other advantages of the instant invention.

Provided is a modified target assembly in which the target fluid is moved within the target assembly in a manner that increases the effective density of the target fluid within the beam path, thereby increasing beam yield utilizing forced convection. The target may also include optional structures, such as nozzles, diverters and deflectors for guiding and / or accelerating the flow of the target fluid. The target assembly directs the target fluid along an inner sleeve in a direction opposite the direction of the beam current to produce a counter current flow and may also direct the flow of the target fluid away from the inner surface of the inner sleeve and toward a central region in the target cavity. This countercurrent flow suppresses natural convection that tends to reduce the density of the target fluid in the beam path and tends to increase the heat transfer from the target.
