  • High output loudspeaker for low frequency reproduction
    Patent number: 4733749
    Abstract: A loudspeaker system for low frequencies has a manifold chamber into which oppositely mounted and aligned woofer units radiate sound. The chamber radiates the sound perpendicularly to the woofer axes, either directly into space or into a horn. An additional back woofer may radiate directly in the perpendicular direction.

  • Technique for bonding a chip carrier to a metallized substrate
    Patent number: 4512509
    Abstract: A template (148), having at least one opening (152) therein, is placed in close, spaced, relation to a PCB (30). The opening (152) is circular with a small semicircular notch (154) on the periphery thereof. A chip carrier (10) is positioned in the opening (152) with one corner (22) loosely captured in the notch (154). The PCB (30), template (148) and the loosely captured chip carriers (10) are placed in a condensation soldering facility to reflow the solder. As the solder reflows the chip carrier (10) rotates slightly about the loosely captured corner (22) to self align pads (33) on the PCB (30) to leads (16) on the chip carrier (10) as the bond is being formed.

  • High pressure condensation soldering, fusing or brazing
    Patent number: 4373658
    Abstract: A high pressure steam condensation soldering facility (10) is described. The facility (10) incorporates a chamber (12) having a centrally located heat processing zone (45) into which high pressure steam is injected to reflow solder on articles (43) therein. A baffle (41) having a conical top portion (51) with a plurality of apertures (52) therein permits controlled amounts of the steam to pass therethrough while redirecting a portion of the steam along the wall (16) of the chamber (12) to interpose a shield of steam between the wall and uniformly heated processing zone (45).

  • Technique for increasing oxygen incorporation during silicon Czochralski crystal growth
    Patent number: H520
    Abstract: A glass crucible (30) for containing a material from which a silicon crystal melt is produced, wherein the inside surface area of the crucible is increased to react with the silicon melt (31) to increase the oxygen content thereof. The inside surface area may be increased by incorporating inwardly directed silica ribs (40) or concentric, hollow silica cylinders (32) as well as forming corrugations (45) or undulations on the inside surface thereof.
