Granted: 1997-05-13
Abstract: This invention embodies a Vertical Cavity Surface Emitting Laser with a top mirror comprising at least one pair of quarterwave layers, each pair consisting of a low index of refraction layer and a high index of refraction layer, the high index of refraction layer being a semiconductor chosen from GaP and ZnS and the low index of refraction layer being chosen from borosilicate glass (BSG) CaF2, MgF2 and NaF.  Especially useful in vertical cavity surface emitting lasers are mirrors formed by a stack of a plurality of pairs of GaP/BSG or ZnS/CdF2. Such mirrors have a high reflectivity characteristics required for an efficient operation of the laser. The GaP/BSG or ZnS/CaF2 mirror structure represents a considerable improvement over previous designs for VCSELs in terms of ultimate reflectivity, low loss, and post growth processing compatibility.

Granted: 1996-10-01
Abstract: Buffers are provided in two elements between which data is to be transferred wherein both buffers are managed solely by the originator of the data transfer.  Only one transfer is required to transmit a message,  and a second transfer acknowledges the completion of the function because message delivery to the receiver is guaranteed under the implemented protocol.   When  a  request  is  sent,  a message  timer  is started at the sender.   When the normal response for the request is received,  the timer is reset; however,  if the duration of the message operation exceeds the timeout value, a message-timeout procedure is initiated.  When the cancel command is issued, a second timer is set.  If this timer is exceeded,  subsequent cancel  commands  can be  issued.   If subsequent cancel commands are issued,  a cancel complete command must be sent and responded to.  Since the commands must be executed in the sequence in which they are received, a response to the cancel complete command ensures that there are no other cancel  operation commands  remaining in the receiver,  allowing subsequent operations to start without danger of being canceled.

Title: Sliding gate terminal unit for air handling system
Inventor: COTE ANTHONY
IPC: F24F13/12
Filed: 1993-12-08
Granted: 1998-08-11
Abstract: A terminal unit for an air handling system and comprised of a housing having a conditioned air inlet for receiving forced conditioned air in the housing.  A main outlet opening and a by-pass air outlet opening are provided in the housing.   An air flow path is defined between the air inlet and the outlet openings. An   air  divider  gate   is   slidingly  displaceable transverse to the air flow path to deflect air entering the inlet to one or both of the outlet openings.   The divider gate has an outlet obstructing rear end and an upstream  deflecting  face.    A  linkage  assembly  is connected to the divider gate to displace the gate across the flow path to simultaneously open one of the outlet  openings  and  close  the  other,   in  equal proportions,   as   desired,   while   maintaining   a substantially constant total  outlet opening  area  as well as maintaining substantially constant inlet air flow  conditions.    An  actuator  device,  such  as  an electric motor or a pneumatic system, is connected to the  linkage  to  effectuate  the  displacement  of  the divider  gate.    The  force  required  to  displace  the divider   gate   by   the   actuator   device   remains substantially constant throughout the displacement of the  gate  during  operating  conditions  of  the  air handling system.

Abstract: The  surge  arrester  contains  two  connection fittings (1, 2) which are spaced apart from one another along  an  axis  and  between  which  at least  one cylindrical  varistor  element  (7)  is  arranged.  The connection  fittings  (1,  2)  and  the  at  least  one varistor  element  (7)  are  clamped with  one  another, accompanied by the formation of contact force, to form a  mechanically  stable  active  part  of  the  surge arrester.  The  active  part  is  surrounded  by  a  cast housing (12) made from insulating material.        The clamping of the active part is achieved by at   least   two   loops   (5)   respectively   acting independently of one another on the connection fittings (1, 2). The loops (5) are arranged at a distance from the at least one varistor element (7). The connection fittings (1, 2) contain bearing areas which correspond respectively to the number of the loops  (5)  and are distributed uniformly about the axis azimuthally and on which a loop end is respectively supported. Despite its simple design, the surge arrester has good mechanical and electrical characteristics and can be produced in a particularly cost-effective way.
