Each lead frame in a continuous strip of lead frames is formed with opposed pairs of integral and subsequently removable aligning tabs for locating a substrate on the lead frame such that leads of the lead frame and respective terminals on the substrate are in alignment. The aligning tabs initially ...

Sharp Donald Jex: Nonreflecting photomasks and methods of making same. Western Electric Company Incorporated, November 23, 1971: US3622319 (167 worldwide citation)

A nonreflecting photomask comprises a pattern of an anodized, film-forming material on a transparent substrate. The thickness of the anodic oxide is chosen such that when the mask is employed in selectively exposing a photoresist-coated body to light (by placing the oxide against the photoresist), d ...

Michael T Gursky: Carrier tapes for semiconductor devices. Western Electric Company, D C Watson, R D Lott, November 18, 1980: US04234666 (132 worldwide citation)

A carrier tape (20) is provided for assembling components to make semiconductor devices. The tape (20) is made from soft, copper foil (21). Patterns (27) containing clusters (24) of inner leads (28) and (30) are accurately formed into tape (20) for bonding to chips (52).

Charles Robert Fegley, Frank Joseph Valentino: Electroluminescent display and method of making. Western Electric Company, R Y Peters, October 18, 1977: US04054814 (127 worldwide citation)

An electroluminescent display device includes at least two elongated, conductive contacts substantially adjacent to and spaced from each other with at least two substantially coextensive ends. A light-emitting element is electrically coupled between the coextensive ends. An elongated insulating base ...

John P W Flemming: Articulated robot arm and method of moving same. Western Electric Company Incorporated, B W Sheffield, September 9, 1980: US04221997 (121 worldwide citation)

An articulated robot arm (10) comprises n arm sections (13, 16, 18, 21) pivotally mounted one to the other. A plurality of independently controlled servomotors (12, 14, 17, 19) at each of the arm joints moves the tip (22) of the arm towards the desired location. All arm angles are measured with resp ...

Dabby Franklin Winston, Kestenbaum Ami: Method of filtering modes in optical waveguides. Western Electric Company, Green Geoffrey D, Sheffield B W, Stavert J L, June 24, 1975: US3891302 (113 worldwide citation)

Modes are filtered in an optical waveguide by selecting and providing a periodic variation, such as a surface corrugation or a refractive index variation, in a filter region in the waveguide. The filter region diverts light in an unwanted mode from the propagation axis by scattering or reflection. B ...

Fred P Partus: Vapor delivery control system and method. Western Electric Company, Robert B Kennedy, June 30, 1981: US04276243 (104 worldwide citation)

A method is disclosed for controlling the delivery of vapor from a bubbler containing a supply of liquid through which a carrier gas is bubbled and from which bubbler vapor is delivered in a vapor stream entrained with the carrier gas. The method comprises the steps of sensing the ratio of vapor to ...
