Abstract: Interlocking means are provided on the front and rear surfaces of adjacent clips to restrain relative movement between adjacent clips in one direction and to permit relative guided movement between adjacent clips in another direction and wherein the restraint of the relative movement is maintained for at least a substantial portion of the movement of the one of the adjacent clips toward a secured position on the support surface. Also, each clip has at least one bore means having first and second cross-sectional configurations so as to provide a shoulder and a surface penetrating fastening device having an enlarged head portion located in the bore means so that, when a force is applied to the surface penetrating fastening device to drive the surface penetrating fastening device into the support surface, the enlarged head will contact the shoulder so that the clip is firmly held in position on the support surface.

Abstract: A mounting method for printed circuit boards provides improved electromagnetic interference reduction while minimizing the required number of mounting screws. A conductive base plate formed with supporting members is configured to mate with a grounding circuit on the board. A central mounting screw places the board in compression to provide electrical continuity between the grounding circuit and the supporting members of the conductive plate.

Abstract: Apparatus for and methods of bonding electrical components or semiconductor chips to a substrate or lead frame is disclosed. According to the present invention, a sawn semiconductor wafer is held upside down in a first substantially horizontal plane and the substrate or lead frame to which it is to be bound is held in a second plane which is below and substantially parallel to the first plane. A die eject head located above the sawn wafer cooperates with a die bond head located between the wafer and the substrate to remove an individual die from the sawn wafer. The die bond head then rotates about an axis which is parallel to both planes and places the die on the lead frame. Also included is a transducer means which is responsive to electrical stimulus for actuating the die eject head and the die bond head such that the interactive force between the heads and the component may be precisely controlled.

Abstract: A method of forming a microwave integrated circuit is disclosed. A hole is bored in an alumina substrate and a plug having a diameter substantially equal to the hole is provided. The hole and the perimeter of the plug are coated with a thermally fusable dielectric composition and the plug is embedded in the hole. Heating the substrate fuses the plug is place and crystalizes the composition into a glass with compatible thermal expansion. At least one face of the substrate and plug are then polished to provide a planar surface. The metalized circuit is then formed on this assembly, which minimizes conductive tracking on the substrate and facilitates alignment of the circuit with the plug.

Abstract: A simple and highly effective method and apparatus for field terminating flat power cable such as used in undercarpet wiring systems. Each conductor, with tightly bonded insulation, of a multi-conductor flat power cable is (at the point of installation in-situ) slotted or cut through with thin narrow slots which leave corresponding narrow rectangular openings through the insulation and conductor. Then a thin conductive device or terminal with corresponding ribs which easily though precisely fit into the slots, is placed in the slot openings, is secured in place on the cable by a suitable means, and the assembly then crimped or flattened together to give a pressure-tight high-conductivity, electrically stable termination only about twice as thick as the insulated conductor. The applicator tooling may be a simple punch and die, and a hammer or pliers. An insulating "bandage" is applied over the termination and bonded to the conductor insulation thereby giving a water-tight joint impervious to corrosion.

Abstract: A permanent magnet motor for use in such electrically-powered devices as appliances, power tools, and the like includes a longitudinally-split cylindrical ferromagnetic wrapper having an inner diameter normally less in its free state than the outer cross-sectional dimension of a permanent magnet array. During assembly of the motor, the split wrapper is expanded to fit around the magnet array, and then is allowed to contract to urge the magnet array radially inwardly against cooperating surfaces formed on each of two end caps. This maintains a predetermined orientation or alignment of the magnet array relative to the armature, including, for example, a predetermined air gap between the magnet array and the armature. Accordingly, the conventional requirement for such additional retention mechanisms as spring clips, adhesives, fasteners, and the like, is eliminated.

Abstract: A hand tool for assisting in the manual closure of integrated circuit (IC) storage and shipping cartridges, includes a base and a shank extending normal from one end of the base and terminating at a grip or stop formation. A pair of tines extends normal from another end of the base, along a direction of the shank. A hinged flap is mounted next to the second end such that it is rotatable to assume a position spaced parallel and extending along the tines. In use, the tines are inserted into an open end of a cartridge full of ICs, with the shank lying along the outer edge of the cartridge and thereafter pressure is manually applied via the tines against an IC to clear a pair of holes in the cartridge and permit insertion of a closure pin through the holes and between the tines. The flap is positioned against the pin to assist in driving the pin into an interference fit. After the pin is inserted the ICs are firmly retained in the cartridge in the well known and desired manner.

Abstract: The present invention is directed to a photocopy prevention film applied to a document to be protected that comprises either a volume holographic refraction grating or a surface holographic refraction grating. The refraction grating is bonded to a document and either causes normally scattered light to be focused toward the photoreceptors of a photocopy machine or causes light normally reflected toward the receptors to be scattered away from the receptors. The film is created by splitting a coherent laser beam into a reference beam and a target beam. The target beam reflects off of a special target and onto a photographic emulsion. The reference beam is also incident to the photographic emulsion. The beam reflected from the target and the reference beam create interference planes within the emulsion which can be developed to create differing refractive index planes within the emulsion or etched away to create a surface grating.
