Bove Ronald: Probe contactor having buckling beam probes. International Business Machines Corporation, Leach Jr Frank C, Saile George O, April 23, 1974: US3806801 (147 worldwide citation)

A probe contactor has each of its probes formed with a length many times its cross sectional area so that the probes buckle or deflect when a predetermined axial load is applied thereto. This enables the same force to be exerted on each of a plurality of pads on a semiconductor chip regardless of th ...

Eaton James H: Method and apparatus for synchronizing droplet formation in a liquid stream. International Business Machines Corporation, Leach Jr Frank C, April 15, 1975: US3878519 (107 worldwide citation)

A source of energy is selectively applied to a liquid stream to reduce the surface tension of the liquid and is applied before the stream would randomly break up into droplets. Both the quantity of energy applied and the time period that the energy is applied are controlled to control the time to dr ...

Hassan Javathu K, Mack Alfred, Wojtaszek Michael R: Method and apparatus for handling workpieces. International Business Machines Corporation, Leach Jr Frank C, Galanthay Theodore E, April 1, 1975: US3874525 (83 worldwide citation)

A semiconductor wafer, which has chips formed thereon, is moved from a class 100 environment into a vacuum chamber in which pattern writing is performed on the chips by an electron beam without significantly affecting the vacuum level in the vacuum chamber. The wafer is initially disposed on an elev ...

Buckley Lawrence Webb, Daniels Raymond Alex, Froula James Dewayne, Knight Arthur Holt, Stapleton Dale Cliffton, Williams George Thomas: Magnetic brush roll having resilient polymeric surface. International Business Machines Corporation, Leach Jr Frank C, February 4, 1975: US3863603 (73 worldwide citation)

A magnetic brush roll of an electrostatic reproduction machine is formed of a non-magnetic core with a resilient polymeric material such as polyurethane, for example, on its surface. The polyurethane surface is textured to provide a desired roughness, is non-abrasive, and is abrasion resistant. Carb ...

Kuhn Lawrence, Myers Robert A, Pennington Keith S, Shah Bankim R: Method and device for detecting the velocity of droplets formed from a liquid stream. International Business Machines Corporation, Leach Jr Frank C, September 23, 1975: US3907429 (29 worldwide citation)

Droplets from a liquid stream are directed between a pair of apertures and a light source, which is strobed at a selected frequency and directed toward the apertures. In one embodiment, the apertures are spaced less than a wavelength of the droplets apart and the light source is strobed at a frequen ...

Gibson David K: Sheet feeding apparatus. International Business Machines Corporation, Leach Jr Frank C, August 19, 1975: US3900192 (26 worldwide citation)

A storage bin, which is to receive sheets on which duplexed images are to be formed by a photocopy machine after a first image is formed thereon, has its rear wall at an oblique angle to the path along which the sheet is traveling from the reproduction portion of the photocopy machine. This causes e ...

Bleau Charles D: Document feed apparatus. International Business Machines Corporation, Leach Jr Frank C, October 7, 1975: US3910570 (24 worldwide citation)

A document, which is fed by a single belt, is prevented from wrapping around the belt as it exits from the belt by a plurality of rollers, which are rotated in the same direction as the belt but with a greater peripheral speed. Each of the rollers, which are axially spaced from each other, cooperate ...
