  • Patent number: 4729764
    Abstract: An irrigation device for injecting and withdrawing liquid from a body cavity, comprising a first chamber separated into two compartments by a partition provided with a one-way valve, wherein one compartment is operatively connected to a rolling diaphragm in combination with a piston member and the other compartment provided with a nozzle adapted to be coupled to a catheter already inserted in the body cavity.A second chamber is removably attached to the first chamber with a gasket and filter member therebetween. With the device filled with irrigating liquid, manually pushing the piston member into the operatively connected compartment forces liquid through the one-way valve into the other compartment and through the nozzle and catheter into the body cavity.

  • Patent number: 4598889
    Abstract: A hinge for control surfaces of model aircraft, comprising a first hinge member formed with a lateral keyhole slot for removably engaging a lateral barbell portion of a second hinge member. The first hinge member is preferably attached to a fixed structure of the aircraft with the second hinge member attached to a control surface, such as, an aileron or elevator. Relative rotation of one hinge member with respect to the other hinge member allows the lateral barbell portion to operatively engage or disengage from the lateral keyhole slot. When engaged, the operatively coacting hinge members provide rotating hinge action between the control surface and the fixed structure of the aircraft.

  • Patent number: 4453262
    Abstract: In order to obtain shorter exposure time and to obtain a longer life in x-ray lithography apparatus, an x-ray target made of tungsten is utilized and the apparatus operated to generate the tungsten M-line, this line being at a wavelength which will be absorbed by the resist normally used in lithography. To develop the resist, which was initially designed for use in an electron beam lithography, a developing method is used in which an initial short development with a high concentration is first carried out followed by a longer, full development with a concentration which is approximately the lowest at which complete development will take place.

  • Patent number: 4437760
    Abstract: A reusable electric overlay measurement base pattern includes a pair of current pads forming first and second pads adapted to be contacted by point contacts, a first conductor of controlled width extending between the first and second pads, a pair of voltage pads forming third and fourth pads suitable for contacting by point contacts, two second conductors extending from the third and fourth pads to the first conductor contacting the first conductor at a predetermined spacing, and a fifth pad disposed adjacent and spaced from said first conductor approximately at the midpoint between the two second conductors. This permits a second level conductor to be deposited extending between the fifth pad and said first conductor which, when perfectly aligned, will intersect the first conductor at its midpoint. The misalignment of the second level conductor can be detected by measurements using the five pads.

  • Patent number: 4425038
    Abstract: Means and methods are provided for controlling the geometry changes in a wafer or mask to permit patterns on the wafer to be matched with projected patterns from the mask. A sealed chamber is provided to receive the edges of the wafer or mask. Pressure is applied from a pressure source into the chamber against the edges of the wafer or mask uniformly in all directions to produce compressive strains until the desired wafer or mask geometry is obtained.

  • Patent number: 4425075
    Abstract: An apparatus for prealigning a silicon wafer prior to transfer to a work station. The wafer is spun on an aligning platform by means of air jets emanating from holes disposed in the surface of the platform while simultaneously being stopped by means of a vacuum source communicating with the surface of the platform. Sensor means detect when the wafer is centered within a first predetermined tolerance to turn off the air jets and vacuum to stop the wafer. Control means responsive to the sensor means then center the wafer to within a second predetermined tolerance. The wafer is then transported to the work station for processing.
