  • Alignment and insertion apparatus for an information-containing disc stylus
    Patent number: 4557040
    Abstract: An apparatus for accurately aligning an information-containing-disc stylus and assembling the stylus to a stylus holder. The apparatus transfers the stylus from a magazine holding a plurality of such styli into a rotary collet which is then rotated by an operator until a laser beam of light is reflected off a known surface of the stylus and impinges on a fixed target. The apparatus then causes the point of the stylus to pierce the stylus holder to a specific depth whereby the stylus is held firmly by the stylus holder.

  • Method for forming a void-free monocrystalline epitaxial layer on a mask
    Patent number: 4557794
    Abstract: A method for forming a layer of monocrystalline diamond cubic material on a mask comprises initially providing a substrate having a monocrystalline surface which is parallel to a {100}-type crystallographic plane. A mask is then formed on the substrate, the mask including at least two apertures and each aperture including an edge which is oriented between 8.degree. and 14.degree. from a particular <001> direction on the surface. The aperture edges are mutually parallel and in mutual opposition and the mask apertures each expose a monocrystalline surface portion of the substrate. The diamond cubic material is then epitaxially grown through the apertures and over the mask so as to form a monocrystalline layer of substantially uniform quality overlying the mask between the edges of the apertures.

  • Apparatus for applying a layer of powder to a surface
    Patent number: 4550680
    Abstract: An apparatus is shown for applying a homogeneous uniform layer of a powder to a surface of a part. The apparatus utilizes two belts which are made to track about two pairs of rollers in unison. A hopper containing the powder having an opening in the bottom is disposed so that the opening is closed off by one or both of the belts except for a slit aperture. The aperture is formed by a space between abutting ends of the two belt-roller assemblies. The apparatus is arranged so that as the belts track about the rollers the aperture traverses the opening in the hopper thereby permitting powder to pass through the aperture and fall to the part to be coated which is positioned directly below the opening.

  • Method for eliminating defects in a photodetector
    Patent number: 4543171
    Abstract: The performance of a photodetector is reduced by the presence of an electrical defect such as a short or a shunt. The invention is a method of improving the performance of this photodetector by preferentially removing a portion of an exposed surface of a detector electrode at the defect site. The preferential etching of the exposed surface is obtained by immersing the photodetector in a chemical etching ambient which has an etching rate for the exposed surface of the electrode which increases with increasing temperature while applying a reverse-bias voltage to the electrodes. The reverse-bias voltage has sufficient magnitude to cause a local increase in temperature of the exposed surface at the defect site.

  • Megasonic cleaning apparatus and method
    Patent number: 4543130
    Abstract: Cleaning apparatus for cleaning semiconductor wafers and the like in a chamber of cleaning fluid vibrating at ultrasonic (megasonic) frequencies utilizing an electrically energized transducer, such as a piezoelectric crystal, mounted on a conductive foil formed of tantalum or zirconium. Pinholes or other ruptures in the foil can cause high energy arcs capable of exploding vapors of inflammable solvents. The foil carrying the transducers is isolated from the cleaning fluid vapors by a closed buffer chamber containing an inert liquid that couples vibratory energy to the cleaning fluid and another closed chamber enclosing the transducers. Accordingly, cleaning fluids, such as the acetones, alcohols and ketones, heretofore considered hazardous fluids, can be used in the apparatus.
