Abstract: A visible light emitting semiconductor laser (50) has a double-heterostructure section above the N type GaAs substrate (10), which is composed of a nondoped InGaP active layer (16) sandwiched between an N type InGaAℓP cladding layer (14) and a P type InGaAℓP cladding layer (18). A P type InGaP thin-film layer (20) formed on the P type cladding layer (18) functions as an etching stopper. Formed sequentially on the etching stopper layer (20) are a P type cladding layer (22a) and an N type GaAs current-blocking layer (24a), which (22a, 24a) have a stripe-shaped groove section (34) in and around their central portion. The groove section (34) has an opening at the top and the bottom portion narrower than the opening, presenting an inverse-trapezoidal cross-sectional profile. This arrangement makes the width of the optical confinement region of the semiconductor laser narrower than that of the current injection region.

Abstract: Serving to control a driving shield (V) when making an underground hollow-profile line from a starting shaft (7) is a measuring arrangement which is arranged at the front end of the hollow-profile line and is moved along with it in the course of driving. The measuring arrangement has a servo-theodolite (T), front reflectors (R), a rear long-distance sight (F), inclinometers for determining the rolling and longitudinal inclination, devices for measuring the length (L) of the driven tube, and also a computer to which the measured values are transmitted for the continuous calculation of the actual position of the driving shield (V) and delivery of control values on-line. The coordinates of the respective location points of the theodolite (T) and of the long-distance sight (F) along the tube axis (S), which coordinates are required for determining the actual position of the driving shield (V), are calculated from the values determined beforehand of the actual position of the driving shield (V) while taking into account rolling and longitudinal inclination of the respective elements of the measuring arrangement. Since an advanced hollow-profile line can only move in the opening cut out by the driving shield and the spatial curve described by the driving shield (V) has been continuously measured by the theodolite (T) and stored in the computer, the actual position of the tube axis (S) is known at the stations at which the actual position of the driving shield (V) has been determined. With the aid of the coordinates of the driving station determined by the length (L) of the driven tube, at which driving station the theodolite (T) and the long-distance sight (F) are respectively located, the coordinates of the location points of the theodolite and the long-distance sight can be deduced in order to calculate from them the actual position of the driving shield (V) in each case. <IMAGE>

Abstract: A single chip integrated data link control (IDLC) device provides full duplex data throughput and versatile protocol adaptation between variably configured time channels on a high speed TDM digital link (e.g. T-1 or T-3 line) and a host data processing system. The device can handle multiple channels of voice and varied protocol data traffic, and thereby is suited for use in primary rate ISDN (Integrated Services Digital Network) applications. Synchronous and asynchronous special purpose logic sections in the device respectively interface with the network and a bus extending to external processing systems. Logic in the synchronous section forms plural-stage receive and transmit processing pipelines relative to the network interface. A "resource manager" element (RSM) (63) and time swap (TS) RAM memory (53) operate to dynamically vary states in these pipelines in synchronism with channel time slots at the network interface, whereby each pipeline operates in multitasking mode to perform plural functions relative to each channel during each time slot. The device also includes integrated memory queues in which communication data and channel status information are stacked relative to the device interfaces. Capacities and modes of operation of these queues are selected to minimize effects on chip size, throughput and cost, while supporting operations in the synchronous section pipelines so that critical time dependencies between consecutive pipeline stages, and between the pipelines and external processors, are lessened.

The outer end portion of the leader (20) is secured to an anchor block (52). On launch, the leader (20) tears loose from the flexible strip (46), the restraining action of which prevents optical fiber predispensing.

Title: Filler apparatus for providing cryogenic liquid coolant to dewars such as those used in radiation detectors
Inventor: HUANG YUCHI
IPC: G01J5/06
Filed: 1991-06-12
Abstract: A filler apparatus for cryogenic dewars, such as are used in infrared detectors in infrared spectrometers, has an inlet port funnel (35) which is connected to a liquid delivery tube (32) which extends downwardly and into the liquid coolant containment vessel (13) of the detector. A gas discharge tube (26) extends co-axially with and spaced outwardly from the delivery tube (32) and is connected to the fill port (30) of the detector to direct gas resulting from evaporation of coolant within the detector up to a gas outlet funnel (27) which is itself co-axial with and spaced outwardly from the inlet port funnel. A screen (45) is mounted over the tops of the inlet and outlet funnels. The coolant, such as liquid nitrogen, is poured by the operator into the inlet funnel, which may be located at a position on the top surface of the cabinet of the spectrometer, and the operator can observe whether the detector is overfilled by noting whether the coolant liquid overflows into the gas discharge tube or up into the space between the inlet and outlet funnels. Because gas resulting from evaporation is directed upwardly and discharged through a space which is separated from the liquid delivery tube, backflowing of the liquid coolant in the delivery tube and funnel is minimized. By allowing the operator to introduce the liquid coolant to an inlet port at the top of the spectrometer cabinet, filling of the detector is simplified.

Abstract: 2.1. In the prior art, injection-moulded articles were filled in a filling station in the region of the injection-moulding machine and then transferred from the filling station to a pallet turret, which has a lift to receive transport units. The releasing of the individual pallets from the transport units takes place with relatively large design and programming outlay, since the transport units usually consist of stacks of pallets. By contrast, the present device should minimise the time for the change both of the pallets and of the transport unit consisting of one or more pallets without increasing the programming outlay. 2.2. To this end, the pallets 55 are individually supported in transport pallets 56. In addition, both during the removal of the pallet from and during transfer of the pallet into the pallet turret, the lift 53 is in a position which permits a transfer of the filled pallet at least at the same place on the transport unit T,T' at which the pallet was removed from this transport unit. 2.3.
