Patent CA-2177196-A1 (CA)
Title: Hybrid illumination system for use in photolithography
Inventor: STANTON STUART
IPC: H01L21/027
Filed: 1996-05-23
Abstract: An illumination system for use in photolithography having an array optical element near the formation of a desired illumination field.  Light or electromagnetic radiation from an illumination source is expanded and received by a multi-image optical element forming a plurality of secondary illumination sources in a plane.  A condenser receives the light from the plurality of illumination sources. A array or diffractive optical element is placed on or near the focal point of the condenser. The illumination plane formed at the focal point of the condenser is within the near field diffraction pattern of the array or diffractive optical element. There is no condenser following the array or diffractive optical element. The use of the array or diffractive optical element permits the use of a condenser between the multi-image optical element and the array or diffractive optical element having a smaller numerical aperture than the emergent numerical aperture of the diffractive optical element, and generates a desired angular distribution with little dependance on the illumination source profile.     When a relay is used, intermediate illumination planes may be spatially separated to form separate X and Y planes that facilitate the formation of a rectangular illumination field.          The relay, unlike a condenser, simply conjugates the illumination plane with another plane or a reticle. Additionally, the use of a diffractive optical element makes possible an illumination field that has a substantially uniform illumination intensity profile along one axis and a trapezoidal illumination profile along a perpendicular axis. This illumination field profile being particularly advantageous in a scanning photolithography operation. In one embodiment, a plurality of optical multiplexers are used to condition the beam prior to being directed through the multi-image optical element. Multiplexing to create secondary beams with small lateral coherence and no mutual coherence enhances the uniformity of spacial and angular profiles. This permits efficient use of the electromagnetic radiation.

Title: Loading mechanism for probe tip tray
Inventor: LAPEUS DAVID J
IPC: B01L9/00
Filed: 1996-05-23
Abstract: In a system for installing, from a supply of disposable probe tips, one such probe tip on a probe for each sample by an automated fluid analyzer system and for removing the tip after each use to allow a fresh tip to be installed, a mechanism for making a fresh supply of tips available in a carrier tray and for receiving and disposing of empty carrier trays.  Multiple probe tip trays, each having a base, a lid, and holding an array of tips are stacked within a chute of the mechanism.  A pair of arms are swung up from a substantially vertical position to a horizontal position beneath the chute.  An associated latch engages the lid of the lowermost tray within the chute while tray guides, which hold the trays within the chute, separate to release the lowermost tray onto the pair of arms.  A delivery rack associated with the analyzer system receives the lowermost tray base from the pair of arms by engaging the tray base with a pair of clips.  The rack then removes the base, and the probes thereon, to the analyzer system.  The pair of arms meanwhile lower and dump the lid into a waste receptacle or disposal chute.  The delivery rack thereafter returns an empty base to the parallel arms, which similarly dump empty base into the waste receptacle or disposal chute.   The cycle is repeated by removing the next tray from the chute.

Patent CA-2196758-A1 (CA)
Title: Temperature control of near-infrared analyzer
Inventor: MOESSNER RICHARD CROSBY
IPC: G05D23/19
Filed: 1995-07-21
Abstract: A preferred temperature control strategy was devised to remove heat from the analyzer and control the optical bench temperature continuously at aim. A foil-type RTD temperature detector is fastened to the optical bench to serve as a measurement input device for a PID control strategy, which is truly aim-seeking. The control strategy employs a heat pipe technology to remove heat from the analyzer enclosure. A heat pipe utilizes a fluid (such as an alcohol) to remove heat by evaporation of the fluid at an internal air circulation heat exchanger and then recondensing the fluid at an external air circulation heat exchanger. The PID temperature controller achieves the desired temperature setpoint by manipulation of heat exchanger fan speeds. The heat removal rate can be very precisely controlled. In practice, both heat exchanger fans could be controlled together, however, to achieve optimal internal temperature uniformity, the internal heat exchanger fan is maintained at full speed and just the external fan is controlled to adjust heat removal rate. Optical bench temperature control is maintained to plus or minus 0.1 degree C vs. a typical temperature control band of plus or minus 2 degrees C.

Abstract: On a démontré que la protéine C de l'homme et la protéine C activée réalisaient une liaison spécifique, sélective, stable et saturée (Kd=30 nM, 7000 sites par cellule) avec l'endothélium de façon dépendante de Ca?2+¿. Le clonage d'expression a révélé un ADNc de 1,3 kb codant pour une nouvelle glycoprotéine transmembranaire de type I capable de fixer la protéine C. Cette protéine semble être un membre de la superfamille CD1/MHC. Comme la thrombomoduline, récepteur impliqué dans l'activation de la protéine C, la fonction et le message du récepteur de la protéine C (EPCR) de la cellule endothéliale sont rétro-régulés par l'exposition de l'endothélium à TNF. L'identification d'EPCR en tant que membre de la superfamille CD1/MHC permet d'apporter des explications sur le rôle de la protéine C dans la régulation de la réaction inflammatoire, et de déterminer des procédés à usage pharmaceutique servant à manipuler la réaction inflammatoire.
