Abstract: An HTSC material epitaxially deposited on a YSZ buffer layer on a surface of a monocrystalline silicon substrate has a zero resistance transition temperature of at least 85.degree. K., a transition width (10-90%) of no more than 1.0.degree. K., a resistivity at 300.degree. K. of no more than 300 micro-ohms-centimeter and a resistivity ratio (at 300.degree. K./100.degree. K.) of 3.0.+-.0.2. The surface of the silicon substrate is cleaned using a spin-etch process to produce an atomically clean surface terminated with an atomic layer of an element such as hydrogen with does not react with silicon. The substrate can be moved to a deposition chamber without contamination. The hydrogen is evaporated in the chamber, and then YSZ is epitaxially deposited preferably by laser ablation. Thereafter, the HTSC material, such as YBCO, is epitaxially deposited preferably by laser ablation. The structure is then cooled in an atmosphere of oxygen.

Abstract: A ventilated work station for wet processing in laminar flow clean rooms is provided in which an aerodynamically shaped baffle comprises four continuous, curved surfaces which direct laminar air flow across the work station without creating hazardous conditions due to loss of fume containment. The laminar flow is further maintained without the creation of undesirable particle concentrating vortices at, or near, the work station surface. The aerodynamic exhaust baffle has two vertical surfaces joined by the two curved surfaces. Exhaust ducts are positioned along the first curved surfaces to thereby enhance the laminar flow contours.

Abstract: A device for stringing a multiplicity of wires through a memory array in a plurality of directions having means for guiding the wires into the array and for capturing the wires leaving the array and means for providing tension on the wires and for directing and causing the wires to pass through the array in the plurality of directions. The guiding and capture means are adapted both to constrain the wires in a preselected configuration and to permit the wires to be easily removed therefrom.

Abstract: A lift for use in a public conveyance such as a bus, train, et cetera, such that a wheelchair can be rolled onto the lift platform at ground level and be transported into the vehicle. The lift platform moves vertically in a well in the vehicle to the passenger level and then rotates into the bus as the doors are closed. Exit from the vehicle is accomplished in the reverse manner.
