  • Patent number: 4591738
    Abstract: A substrate voltage generator is disclosed which provides over 1.5 times as much current for a given size circuit, as has been capable with prior art substrate voltage generators. This is achieved by means of a high capacitance per unit area charge pumping capacitor having a triple plate structure and further through the space saving technique of providing a dual use for the source diffusion of the current sinking device in the circuit so as to also serve as the guard ring around the charge pumping circuit of the substrate voltage generator. These and other features of the substrate voltage generator circuit enable relatively large quantities of current to be supplied for maintaining the substrate voltage in large dimension VLSI chips having significant diffusion leakage currents.

  • Patent number: 4585351
    Abstract: A hybrid integrated circuit (10), having a plurality of chip carriers (12) mounted thereon, is positioned on a nest (50) of an apparatus (30). An operator, while activating pneumatic switches (58), moves a selected one of the plurality of chip carriers (12) to an inspection site. A sensor plunger (62) detects the presence of the chip carrier (12) and enables a positioning assembly (34), which centers the chip carrier within the inspection site and locks the nest (50), to prevent further movement thereof. A viewing adaptor (70) is then lowered about the selected chip carrier (12) to enable the operator to simultaneously inspect all solder joints (22) positioned beneath the selected chip carrier. Thereafter, the operator releases switch actuator (60) which allows the viewing adaptor (70) to be raised and enables the positioning assembly (34) to unlock the nest (50) so that another chip carrier (12) may be moved to the inspection site for inspection by the operator.

  • Patent number: 4547960
    Abstract: Leads (22) of an electrical component (20) are positioned within and extend through a plurality of apertures (74) formed through a substrate (54). The substrate (54) includes a circuit (56) formed on one major surface thereof and a plurality of contacts (76) mounted thereon which is electrically connected to the circuit (56) and which overlaps a portion of the appropriate one of the plurality of apertures (74) formed therethrough. A lead pusher (32) moves the leads (22) into engagement with the contacts (76). Thereafter, free ends of the leads (22) are moved beyond a point of engagement between the leads and the contacts (76) so that the lead is flexed to insure a firm engagement between the leads and the contacts.

  • Patent number: 4545636
    Abstract: A base housing unit (32), which supports a connector (48) on a bottom wall (40) thereof, includes a vertical boss (46) spaced from the connector to provide a cable receiving recess (70). An elongated slot (42) is formed through the vertical boss (46). A first end section of a flat cable (10), having accordion pleat sections (64, 66 and 68) formed therein, is threaded through the elongated slot (42). The pleat sections (64, 66 and 68) are positioned within the recess (70) and the first end section of the cable (10) is terminated on the connector (48). A cover (50) is then secured to the base housing unit (32). In response to the application of tension to a free end of the cable (10), the pleat sections (64, 66 and 68) flex to bind the cable between the connector (48) and the cover (50).

  • Patent number: 4516737
    Abstract: A storage reel (10, 10') particularly adapted for winding bandoliered, axially leaded, tubular components thereon, such as capacitors (18), includes a core (12, 12') formed with a uniquely configured peripheral relief (32, 44, 46). The relief, in accordance with one preferred embodiment (32), has a concave base, and is dimensioned to accommodate the lower half body portions of a predetermined number of bandoliered, forward end capacitors (18), when wound as part of the first wrap of such components on the core, via a pair of laterally spaced lead-supporting tape carriers (26, 27). The relief is centrally located on the core so as to define on each side thereof a circumferentially displaced, lead-supporting peripheral core border region (12a or b).

  • Patent number: 4516739
    Abstract: The tension imparted to an advancing strand 11 is regulated by passing the strand about a permanent magnet sheave 13 interposed between a pair of permanent magnet discs 19 and 21. The sheave and discs are axially polarized so that the magnet fields about the sheave are in opposing or repelling relation with the magnetic fields about the discs. By moving (26, 27 and 28) a disc toward or away from the sheave the intensities of the coupled lines of magnetic force are increased or decreased to accordingly vary the magnetic drag placed on the sheave and thus the tension imparted to the advancing strand 11.

  • Patent number: 4456876
    Abstract: A frequency counter (20) measures and displays a plurality of frequencies appearing on input channels (22, 24, 26 and 28) of an analog circuit (30). A program switch (32) is coupled to a decoder logic circuit (34) which facilitates the operation of counter (20) in one of a plurality of selectable program modes. A steering logic circuit (36) is coupled to circuit (34) and facilitates the selection and order of the input channels (22, 24, 26 and 28) during a measurement cycle. Toggle switches (38, 40 and 42) are coupled to circuit (36) to facilitate the establishment of a sign bit, a channel order and a channel select, respectively. A channel display circuit (46) provides visual indication of the sign, channel select and channel order.

  • Patent number: 4431474
    Abstract: A thermocompression bonding apparatus (10), which is particularly adapted to bond an array of miniaturized electrical leads (36) to a corresponding array of respectively aligned pads (33) of a metallized circuit, supported on a substrate (31), includes a specially constructed and internally heated bonding thermode (12) that is uniquely pin-coupled at an upper surface midpoint portion thereof to the lower end of a single support rod (54). The latter is resiliently supported at its upper end, preferably through the use of a plurality of coaxially mounted Belleville washers (77), within an oversized central bore of a three-plate support assembly (14). The latter is, in turn, adapted to be secured to a reciprocally driven member, such as a multipost-mounted platen (16), of the composite apparatus.

  • Patent number: 4415773
    Abstract: A PBX system (20) receives a predetermined number of dialing digits from a central office which represents a subscriber station interconnected within the system. The system (20) adds a pseudo digit to the dialing digits to facilitate: (1) the use of a full compliment of dialing digits; and (2) the establishment of a switching connection with the subscriber station. The pseudo digit is then removed and the remaining dialing digits are translated into an equipment location for the subscriber station. Thereafter the switching connection is established with the subscriber station.

  • Patent number: 4399532
    Abstract: A second-incoming call appears at an attendant facility (34) within a PBX system (20) while the attendant is awaiting a response on a first-incoming call. The attendant activates an overlap button (35) to facilitate the conversion of the first-incoming call into a listen-only connection. The attendant then establishes a two-way connection between the attendant and the second-incoming call to be served by the PBX system (20). Thereafter, the attendant monitors the first-incoming call on a listen-only basis while simultaneously serving the second-incoming call associated with the two-way connection.

  • Patent number: 4398628
    Abstract: A plurality of pins (20) are supported and held within a pin supporting shuttle (54) by wedging the shank portion (24) of each of the pins between a respective one of a plurality of spaced parallel channels (58) and a ramp (62). The shuttle (54) is then moved to place a free end of each of the pins (20) in a gripped position within an insertion apparatus (55). The shuttle (54) is manipulated so that the shank portion (24) is allowed to return to a normal axis of each respective pin (20). The shuttle (54) is then removed from about the pins (20).
