Abstract: A method of achieving radial (x,y) alignment between an active device subassembly and an optical fiber subassembly of an optical package is disclosed. The method relies on the use of mating sections with essentially identical outer diameters. The subassemblies are brought into contact and are first joined at the two points where the edges of the piece parts coincide (flush points). It has been determined that by continuing the attachment process at symmetric locations about one of the flush points, minimal disturbance of throughput efficiency will be maintained. The optical throughput is continually monitored to determined at which particular flush point the attachment process should proceed. In particular, as soon as the throughput efficiency drops below a predetermined value, the attachment process is rotated to continue at the opposite flush point.

Abstract: A container (30) for enclosing an article (10) includes a base (32) having a bore (33) and a counterbore (34) for holding the article (10) such that a first, often delicate, portion protrudes from a first end of base (32). Base (32) has peripheral surfaces (37) primarily for engaging a cover (40) for closing container (30). The cover (40) has an interior cavity (42) and portions (53-55) which close over and limit air entrapped with the article (10). Cover (40) also has peripheral walls (48) containing fixed ends (49) and free ends (50) with internal surfaces (51) therebetween for engaging the base (32). The engagement surfaces (37 and 51) of the base (32) and cover (40), respectively, preferably have an interference fit. Also, the cover walls (48) are sufficiently long that the cover (40) substantially aligns to base (32) and stays clear of article (10) during closure. Accordingly, unwanted contact of cover (40) to the first portion of the article is avoided.

Abstract: At least one article such as a device (10) is reoriented to achieve uniform orientation of a plurality thereof. The devices (10) typically have a head (12) and a body portion (18) depending therefrom along a plane (26) dividing the head asymmetrically. A portion of head (12) has a fully developed shape typically seen along one side of a disc while another portion of head (12) has at least one segment omitted. A preferably air powered track (30) is utilized to guidably advance the devices (10) in a single file. The body portions (18) are disposed in track (30) with their respective dividing planes (26) lying substantially along a common plane passing through a longitudinal slot (50) in a feed section of track (30). A device (10) is assumed to have a desirable orientation when its flat (24) faces such as to the back of track (30) and an undesirable orientation when flat (24) faces oppositely such as to the front of track (30).

Abstract: Individual ones of articles such as (LED) devices 10 are fed and positioned at one or more stations along a path traversed by the devices. A track 30 guidably advances the devices 10 in single file to and beyond stations 63 and 64 successively located along the path represented by a channel 35 in the track 30. An assembly 50 shuttles, transversely of the channel 35, a plurality of fingers 66-70 simultaneously from a working state to and from a transitory state with respect to devices 10 in channel 35. The fingers may be in the form of thin, upright blades 66-70 which are engaged to assembly 50 and extend substantially normally of and into channel 35 in response to the shuttling. An indexing blade 68 extends from the front of and into channel 35 when shuttling assembly 50 is in the working state to block a waiting file of devices 10.

Abstract: A workpiece such as a minute stud (34) is aligned to a small porcelain body (36) to form a guide (40) for processing lightwaves. Such alignment includes registering a target (30) of an avalanche photodiode in a chip (32) on the stud (34) to a fiber receiving bore (44) in the body (36). Radiation, preferably in the form of a beam of light, is directed to a first end of the bore (44). Some portion of the light is redirected sufficiently to pass longitudinally along the surfaces of the bore (44) and thereby project an image from a second end of the body (36). The image is advantageously in the form of a halo which is enlarged and displayed on a video monitor (100). The stud (34) is manipulated about the first end of the bore (44) by operating micropositioning fixtures (66 and 68). The target (30) in chip (32) reflects light sufficiently to cast a preferably dark image of the target ( 30) through the bore (44) and its image onto the video monitor (100).

Abstract: A workpiece such as a miniature stud (10) supports a chip (20) having a heat and light sensitive device therein. Such stud (10) is thermally bonded to an insulative body (12) to form a guide (14) for converting light to electrical pulses. A positive and a negative electrode (44 and 45), respectively, are each connected to a respective pole of a power supply for providing electrical current adequate for the bonding. A resistance heating element (42) conducts the current from electrode (44) at least partially along a path through the stud (10) to electrode (45). For stud (10), the path is selected preferably by providing a thru hole (90) in element (42) under the position occupied by the heat sensitive device when stud (10) is placed upon the element (42). The current concentrates in stud (10) along an annular ring (29) where heating is required sufficiently to thermally bond at least the ring (29) of the stud (10) to the body (12).

Abstract: A fluid dispensing anti-burglar device is disclosed in which a chemical irritant such as tear gas is discharged into the area to be protected when an intruder forces entry into the area to be protected with which the device is associated.

Abstract: First components such as lids (9) are assembled to second components such as electronic chip carriers (10). Each lid (9) has an external surface opposite a first mating face and each carrier (10) has a second mating face complementary with the first mating face of the lid (9). An assembly station contains a first frame (30) having first walls (31-35) for confining and first ledges (37-38) for supporting a lid (9). Frame (30) has an advantageous peripheral opening (39) suitable for passing therethrough portions of devices for transferring lids (9). Preferably such stations (25) are established in an array suitable for access by an array of lids (9) transferred by a first device (35). A first magazine (70) holds files of lids (9) with external surfaces of leading ones in an array for contact, pickup and transfer.

Abstract: Contact pads (18) of a device (12) are adapted for bonding components such as contacts of a circuit assembly thereto. At least two of the pads (18) are interconnected with a member (34) containing bonding material. Portions of the member (34) lying adjacent the pads (18) are then removed to form isolated bodies (42) containing bonding material on the pads (18). The member (37) may be of a composite structure containing bonding material associated with a hard element (61). The bodies (42) formed therefrom contain a hard element portion (62) having dimensions which remain substantially unchanged to define a desired minimum distance between respective pads (18) and contacts when they are bonded together.

Abstract: An electroluminescent display device includes at least two conductive leads spaced from each other with a light-emitting element electrically coupled between such leads. A transparent, insulating base is formed about and between the leads. The base encapsulates both the leads and the light-emitting element.At least one lateral portion of each lead extends beyond the base and substantially conforms to the configuration of the base. In conforming such lateral portions, they are preferably wrapped around the base and fixed to it. These lateral portions are arranged so that light from the light-emitting element may pass axially through the base and out of its ends. In addition, light may pass laterally out of the base.The device may also be used for circuit protection purposes. To so use the device, a protective element is electrically coupled between the leads so that upon the occurrence of an overload condition in an external circuit coupled to the lateral portions, the protective element decouples the leads.

Abstract: In making electronic components, it is usually necessary to test and sort the components in accordance with their characteristics. In carrying out such operations, the components are guided along a first portion of a path tangential to a rotatable member having notches spaced in the periphery thereof. The rotatable member is moved to engage one notch with each component to support such component and to space it from the other components in accordance with the spacing of the notches. The rotatable member controllably moves the articles along a second portion of a path adjacent the first portion. The rotatable member is then stopped and the leads of each supported component are straightened. The components are then fed to another rotatable member and controllably moved to a testing facility. While the other rotatable member is stopped, the leads of each component are engaged by contacts of the testing facility to determine certain characteristics of each component.

Abstract: In making semiconductor devices such as integrated circuits, semiconductor wafers are often sorted according to both their thickness and their resistivity. To so sort the wafers they are moved successively along a first track to a thickness determining device which produces a signal indicative of the thickness of each wafer. This signal is stored by a computer. Continued successive movement of the wafers brings them to a resistivity determining device. This device, which is rendered effective by the stored thickness signal, produces a signal indicative of the resistivity of each wafer. The resistivity signal is stored by the computer. The successive movement of the wafers is continued along the first track to move them onto a second track. Each article is moved successively along the second track. And, in response to the stored signals, each article is moved into a preselected position associated with both the thickness and the resistivity of each article.

Abstract: An optical package includes a two-piece fiber subassembly which allows for separate axial and radial alignment of the fiber to the active optical device. The subassembly consists of an inner ferrule encasing the fiber and an outer sleeve which holds the ferrule. The ferrule is moved axially within the sleeve to perfect the axial alignment of the fiber and the device. The sleeve includes a number of openings around its circumference to expose the ferrule. Once axial alignment is achieved, the outer sleeve is attached to the ferrule through these openings to fix the axial alignment.
