Abstract: Articles to be sorted are loaded into carriers (36) which move along a predetermined path that has groups of receptacles (112,114,116,118,120,122,124,­126,128,130) under and adjacent to it. Each carrier (36) has gates or doors (54) which are normally "closed" to define a bottom that can hold an article within that carrier (36), but which can be "opened" to release that article for direct transfer into a selected one of the receptacles (112,114,116,118,120,122,124,126,­128,130), all of which are positioned below the level of that carrier (36). The gates or doors (54) of the carriers (36) are arranged so they can selectively and directly transfer articles into the centermost of a group of transversely-positioned receptacles (112,114,­116,118,120,122,124,126,128,130), into the receptacle (112,114,116,118,120,122,124,126,128,130) that is disposed outwardly of that centermost receptacle (112,­114,116,118,120,122,124,126,128,130), or into the re­ceptacle (112,114,116,118,120,122,124,126,128,130) that is disposed inwardly of that centermost receptacle (112,­114,116,118,120,122,124,126,128,130). As a result, the direct transfer sorting system (20) of the present in­vention obviates the bulky and expensive chutes and guides which have been required by prior sorting systems.

Abstract: This invention is for improving the radiation hardness or radiation resistance of GaAs MESFETs. According to this invention, an n-type active layer (2) is formed by doping in a GaAs crystal (1). The n-type active layer (2) includes an upper layer (21) and a heavy doped lower layer (22). A Schottky gate electrode (6) is provided on the active layer (2), so that the carrier concentration in the active layer (2) and the thickness of the active layer (2) are set to required values. According to this invention, not only in the case of a total dose of exposure radiation of R=1x10⁹ roentgens but also in the case of a higher total dose, at least one of the threshold voltage V th  of the GaAs MESFET, the saturated drain current I dss  thereof, and the transconductance g m  are in their tolerable range. Consequently, a semiconductor device comprising the GaAs MESFET and a signal processing circuit cooperatively combined therewith can operate normally as initially designed, with a result of considerably improved radiation hardness.

Title: Optical fiber coupling
Inventor: ALAMEEL GEORGE M
IPC: G02B6/38
Filed: 1989-03-16
Abstract: A coupling (20) for backplane connections of an optical fiber arrangement facilitates superbly alignment of optical fibers notwithstanding blind insertion of a portion of the arrangement. The coupling arrangement includes a housing (70) which has a first end portion (52) and a second end ' portion (49) and which is mounted in an opening of a panel (32) such that it floats and is capable of three dimensional adjustive movement to facilitate alignment of plugs which terminate optical fibers and which are inserted into opposite ends of a sleeve (84) disposed in the housing. A longitudinal movement of the coupling is facilitated by a compression spring (102) which is disposed about the housing between the backplane and a retaining member (104). Advantageously, the second end portion of the housing is tapered inwardly to cause the plug (80) of a card (40) which is inserted blindly into the second end portion of the housing to cam against the entrance of the housing to cause the coupling to be repositioned in the panel opening. A dimensional ratio of a portion of the housing between the tapered second end portion and the sleeve cooperates with substantially frictionless washers (103-103) which engage ends of the spring to cause any movement of the coupling as the plug is inserted into its second end portion to be substantially translatory thereby insuring end face contact of the plugs to obtain a low loss, low reflection connection.

Abstract: An optical beam scanner, for reading a bar-code, comprises a housing (10) accommodating therein a beam generator (1) for projecting a laser beam (34) along a fixed axis, a rotary mirror (30, 40) rotatable about its axis (32) and having a plurality of reflection surfaces (30a, 30b) arranged in a polygonal manner on the periphery of a body thereof, which surfaces receive and reflect the laser beam (34) projected from the beam generator (1), and a unit for driving the rotary mirror (30) to rotate at a predetermined speed during the operation. The housing is provided with a window (21) on an upper wall thereof, through which passes the laser beam (35) reflected from the respective reflection surfaces (30a, 30b) of the rotary mirror (30) for scanning a bar-code disposed above the window (21), and each of the reflection surfaces (30a, 30b) of the rotary mirror (30) is formed by a part of a circular cylin­drical surface cut out along a height thereof in an elongated rectangular shape and disposed so that a ridgeline (33) is transverse to the axis (32) of the rotary mirror (30). A direction of a normal vector to the reflection surface (30a, 30b) is smoothly varied in one direction along a scanning line (X) on the reflec­tion surface (30a, 30b) traced by sequential points of incidence of the laser beam (34) across the reflection surface (30a, 30b) when the rotary mirror (30) is rotated, whereby the reflected beam (35) traces various linear scanning patterns (A, B), each corresponding to the respective reflection surface (30a, 30b), on a plane of the window (21) above which the bar-code is scanned. 
     An optical beam scanner embodying the present invention can be cheaper to manufacture, and smaller in size, than prior art beam scanners.
