    摘要： A collapsible instrument stand for suspending an elongate instrument in a vertical orientation. The instrument stand generally includes three basic members: a base member which supports the stand, a head member from which an instrument is suspended, and a first member which rigidly supports the head member. The base and head members are preferably attached to respective ends of the first member in a pivotable manner. When configured for use, the base and head members are folded out to be generally orthogonal to the first member. When configured for storage and/or transportation, the base and head members are folded to become flush with, and generally be collateral and/or coplanar with the first member. In the latter configuration, the instrument stand can be stored within a flat outer compartment of an instrument case, if not within the instrument case itself.

    摘要： A topcoat material for applying on top of a photoresist material is disclosed. The topcoat material comprises a polymer which is sparingly soluble or insoluble in water at a temperature of about 25° C. or below but soluble in water at a temperature of about 60° C. or above. The polymer contains poly vinyl alcohol monomer unit and a poly vinyl acetate or poly vinyl ether monomer unit having the following polymer structure: wherein R is an aliphatic or alicyclic radical; m and n are independently integers, and are the same or different; and p is zero or 1. The topcoat material may be used in lithography processes, wherein the topcoat material is applied on a photoresist layer. The topcoat material is particularly useful in immersion lithography techniques using water as the imaging medium. The topcoat material of the present invention are also useful for immersion lithography employing organic liquid as immersion medium.

    摘要： A dental hand piece includes a reference line generator attachable to the face of a patient to generate a reference line in parallel to the top surfaces of the teeth of the patient, and a directional guider, for example, laser guider located on the front end of the hand piece body for generating a horizontal light beam for alignment with the reference line and a vertical light beam for indicating the hole-drilling position to help the dentist in drilling a hole perpendicular to the occlusal surface for accurate installation of a fixture to assure a successful dental implantation surgery.

    摘要： A design strategy for constructing hierarchically structured materials using nanoparticles and synthetic biopolymers has been developed. Block copolypeptides or homopolymer polyelectrolytes are used as structure-directing agents to arrange nanoparticles (composed of metals, metal non-oxides, metal oxides, or organics) into unusual microstructures, such as spheres, “apples” and “cups.” Hollow spheres can be made wherein nanoparticles of one composition are spatially oriented completely interior or exterior to nanoparticles of a second composition. These aggregates contain nanoparticles only in the shell walls, and maintain their hollowness upon calcination. These shapes can also be fabricated into films. These robust materials are anticipated to have great promise in applications that require surface catalysis, magnetic/electronic/optic properties, transport capabilities, and combinations thereof, such as drug delivery, packaging, catalysis, and sensors.
