Abstract:
A method and apparatus for achieving a consistent depth of immersion of a semiconductor element into an exposed surface of an adhesive material pool when applying the adhesive material, conductive or non-conductive, to the semiconductor element or portion thereof. The consistent depth of immersion is defined by a stop which is attached to a reservoir used to form the adhesive material pool, attached to a stencil which is used in conjunction with the reservoir to form a level upper surface on the adhesive material, or operates independently from the reservoir and/or stencil.
Abstract:
A method and apparatus is disclosed for sequential processing of integrated circuits, particularly for conductively passivating a contact pad with a material which resists formation of resistive oxides. In particular, a tank is divided into three compartments, each holding a different solution: a lower compartment and two upper compartments divided by a barrier, which extends across and partway down the tank. The solutions have different densities and therefore separate into different layers. In the illustrated embodiment, integrated circuits with patterned contact pads are passed through one of the upper compartments, in which oxide is removed from the contact pads. Continuing downward into the lower compartment and laterally beneath the barrier, a protective layer is selectively formed on the insulating layer surrounding the contact pads. As the integrated circuits are moved upwardly into the second upper compartment, a conducting monomer selectively forms on the contact pads prior to any exposure to air. The integrated circuits can then be transferred to an ozone chamber where polymerization results in a conductive passivation layer on the contact pad.

Abstract:
There is provided a plating device that can easily form a uniform plated film on the surface, to be plated, of a material. The plating device includes: a holder for holding a material with its surface, to be plated, upward and its peripheral portion of the surface, to be plated, sealed; a heated fluid holding section for holding a heated fluid which is allowed to come into contact with the back surface of the material held by the holder to heat the material; and a plating solution supply section for supplying a plating solution to the surface, to be plated, of the material held by the holder.
Abstract:
The invention relates to a process for introducing fluids into a solids flow of a spouted bed apparatus, as well as an associated apparatus. For the present invention, it is characteristic that at least one circular solids flow is formed in the axial direction of the reaction space of the spouted bed apparatus, for which the inlet air required for forming the solids flow is fed through a gap in the lower region and in the axial direction of the reaction space and the fluid is introduced by means of one or more single or multiple-component nozzles at one or more positions into the solids flow. Therefore, the flow conditions in the injection region can be set, so that the fluid can be introduced selectively and adjustably into the solids flow. The resulting end product distinguishes itself through approximately equal grain size with equal material properties. Through the spraying of pure fluids, solutions, molten masses, or the like through one or more single or multiple-component nozzles into the solids flow, different end products can be produced.
Abstract:
A split-pan for a panning apparatus, a panning apparatus incorporating a split-pan, and a method of coating two distinct masses of centers simultaneously with the split-pan are described. The split-pan is formed as a hollow drum, having first and second ends, an interior volume, and at least one partition, positioned between the first and second ends. The partition divides the interior volume into a plurality of coating vessels that allow the simultaneous coating of a plurality of masses of centers in the respective coating vessels.
Abstract:
The subject of the invention is a process for the continuous dip-coating of a metal strip (1) in a tank (11) containing a liquid metal bath (12), in which process the metal strip (1) is made to run continuously through a duct (13), the lower part of which is immersed in the liquid metal bath (12), in order to define with the surface of the said bath a liquid seal (14). In the region where the strip (1) leaves the liquid metal bath (12), the liquid metal is isolated from the surface of the said bath in an isolating enclosure (20) and the metal oxide particles and intermetallic compound particles are recovered by the liquid metal flowing from this region into the said enclosure (20) and the said particles are extracted from this enclosure (20). Another subject of the invention is a plant for implementing the process.
Abstract:
Procedure for the preparation of organic tissue samples for the further examination and clinic or scientific study thereof and the corresponding machine of the type having a plurality of circularly arranged beakers (3) turntable containing different processing liquid compositions (2) and a basket (1) containing the samples, consisting said procedure in the addition of the agitation phase of the stratified composition of the processing liquid, which is performed through a clockwise self-rotating rotary movement of the basket (1) immediately followed by a further movement in the opposite direction; the gravity draining phase is replaced by the centrifugal phase and the further optional translation thereof to eventually be received in the next beaker carrying a different composition.
Abstract:
The present invention provides a method and apparatus for dispensing a small volume of a selected liquid, such as a biological sample or reagent, onto a substrate. The device includes a tube adapted to contain the liquid. An elongate fiber is disposed within the tube for axial movement therein between raised and lowered positions. Upon shifting or oscillating the fiber between its raised and lowered positions, a liquid spot can be formed at a selected position on the substrate. The device is readily adaptable for the production of micro-arrays having a great number of individual spots.
Abstract:
An installation for treating, in particular coating, articles (4), especially vehicle bodies, comprises at least one bath (2, 3), in which a treatment liquid, in particular a paint, is located. The articles (4) are intended to be immersed therein. The conveying means with which the articles (4) are conveyed through the installation in a continuous or intermittent translational movement comprises a plurality of transport carriages (5), which run in guided manner on running surfaces (13, 14). Each transport carriage (5) comprises a separate drive (28, 29) for translational movement and a drive (19, 20, 24, 25) operating independently thereof for the immersion movement. The installation thus constructed is extraordinarily flexible, since the immersion movement does not have to correlate with the translational movement. The transport carriages (5), optionally carrying different articles (4), may miss out individual baths (2, 3) without effecting an immersion process, perform the immersion movement from different directions at different speeds, travel at different speeds and thereby enlarge or reduce distances from preceding transport carriages (5) and, if required, be individually removed from the transport line.
