摘要： A lightguide preform (13) is fabricated by depositing and consolidating a plurality of doped silica layers (12), containing volatile germania, on the inside surface of a silica glass tube (11). The tube (11) is rotated while repeatedly traversing a hot zone therealong to shrink and collapse the tube in a final heat zone traversal. A gas mixture containing oxygen and germanium tetrachloride flow from an input gas line (23) and through the tube (11) during the shrinking traversals. The gas mixture continues to flow through at least a portion of the input gas line (23) during the final heat zone traversal.

摘要： The walls 41 (FIG. 4) of thru holes 11 in a printed wiring board substrate 12 are coated with a liquid 24 by inserting fingers 22 into the thru holes. Each of the fingers has a diameter slightly less than the diameter of the associated thru hole and has a length no greater than the thickness of the substrate 12. After ink 24 has been applied to the top surface of the substrate, the inserted fingers 22 are withdrawn, thereby drawing the ink down into the thru holes and coating the walls 41. In another embodiment, fingers 62 are aligned with selected portions 52 of an edge 55 of the substrate 50 to coat the portions of the edge as the fingers are moved by the edge after the heads of the fingers have been coated with the ink 24.

摘要： A workpiece (16), for example a magnetic bubble memory wafer, is held in place, and heat is removed from it by an expandable heat pipe (22) during a process performed in a vacuum as, for example, a sputter etch process. The expandable heat pipe (22) includes two plates (24, 26) joined by a bellows (28) to form a sealed chamber containing a vaporizable liquid such as water. During loading of the wafers the heat pipe (22) is compressed by atmospheric pressure and thereby facilitates easy assembly of the wafer (16) and heat pipe (22) into a holding fixture (10) which in turn is bolted to a cooling plate (30) situated inside a vacuum chamber. When the chamber is evacuated, the heat pipe (22) expands to hold the wafer (16) in place and form a good thermal path from the wafer (16) to the cooling plate (30). In an alternate embodiment the heat pipe (22) does not completely fill the gap from the wafer (16) to the cooling plate (30) in a vacuum at room temperature, but rather expands to fill the gap when the heat pipe (22) is heated by the wafer (16). The expanding heat pipe (22) holds the wafer (16) at a constant, predetermined temperature above the temperature of the cold plate.

摘要： A strip 20 has a drive margin 36 and a latent image of a pattern in a light sensitive coating 73 of a pattern portion 22 thereon. To avoid disturbing the pattern, the strip 20 is gripped by the drive margin 36 using a set 43 of pinch-drive rollers which drive the strip without disturbing the latent image. The strip 20 is driven through pattern development, cleaning and etching solution spray chambers 64, 66 and 108, respectively. One or more adjustable shields 78 are used to vary the time interval during which the strip 20 is sprayed by these solutions. By adjusting one or more shields 78 to suit changes in solution condition the time intervals for proper developing, cleaning and etching are coordinated for a speed at which the strip 20 is driven.

摘要： A carrier tape (20) is provided for assembling components to make semiconductor devices. The tape (20) is made from soft, copper foil (21) and eliminates a plastic substrate (12) of the prior art. Patterns (27) containing clusters (24) of inner leads (28) and (30) are accurately formed into tape (20) for bonding to chips (52). Patterns (27) also contain precisely located sprocket holes (22) for indexing the tape (20) for chip and lead bonding.Tape (20) is indexed for bonding the free ends (36) of inner leads (28) and (30) to pads (54) of chip (52). Then tape (20) is indexed for bonding fixed ends (34) of leads (28) and (30) to stiff outer leads (86).Leads (28) and (30) in cluster (24) are deformed into a precise bell-like shape called a "bug" with chip (52) riding horizontally on top of the bell. Bugging develops flexural and tensile stresses and bonding causes thermal stresses in leads (28) and (30). Such stresses can shift or twist bug (51); warp the structural margin (26) and holes (22) of tape (20), and they can distort adjacent lead clusters (24) on tape (20).One or more stress relief sites (39) are provided in leads (28) and (30) to uniformly control such stresses. Sites (39) advantageously prevent stresses from being transmitted outside cluster (24). Also sites (39) aid in deformation of leads (28) and (30) to form bug (51).Tape (20) contains a high density of lead clusters (24) per linear foot of web (21). Costly plastic substrates (12) are eliminated. More precise registration of leads occurs at bonding. And good bonding improves thermal cycling performance of assembled devices. Also proper bugging assures good posture of chip (52) on top of bug (51). And good bugging reduces likelihood of short circuiting in the assembled devices.

摘要： Hermetically sealed electronic articles (11) such as, for example, diodes are leak tested by exposing the articles to a fluid (28) under pressure. The fluid is capable of altering the electrical characteristics of the articles to a value outside of an acceptable range of values upon penetrating through faulty hermetic seals of the articles (11). After such exposure the articles (11) are routinely tested and the articles with values of their characteristics outside the range of acceptable values are identified or discarded. Ethylene glycol is an example of a preferred fluid (28) in that it has conductive properties which significantly increase the reverse bias leakage current of the diodes.

摘要： The diameter of an optical fiber is continuously measured by directing a laser beam at the fiber to form a light intensity fringe pattern. The pattern is converted to a substantially sinusoidal electrical signal having a period proportional to the fiber diameter. The sinusoidal signal is forwarded to a tapped delay line to form a plurality of delayed replicas thereof having a predetermined delay therebetween. A pulse is generated for each zero crossing of all the sinusoidal signals and the pulses interleaved to form an output train having an interpulse interval proportional to a fraction of the fiber diameter.
