Inventor: ROBERTS MATTHEW A
IPC: C40B60/14

Abstract: On utilise la photoablation au laser ultraviolet afin d'effectuer la structuration tridimensionnelle de substances biologiques et chimiques sur la surface de substrats polymères ou d'autres substrats absorbant les ultraviolets. Ce procédé permet de créer des lignes d'ablation, des trous ou des réseaux entiers de structures pouvant contenir sélectivement une substance chimique et présenter des dimensions critiques dans une plage de 1-1000 νm. On envoie des impulsions d'énergie élevée sur un substrat polymère protégé (2). On utilise pour cela un laser excimère ultraviolet qui crée par ablation (3) une cavité traversant la couche protectrice et pénétrant à l'intérieur du substrat sous-jacent. On peut fabriquer des structures géométriques complexes par utilisation répétée du laser à travers une série de masques sur des substrats fixes. Les structures polymères à ablation obtenues présentent une rugosité accrue, ce qui amplifie la surface de fixation des récepteurs chimiques ou biologiques, y compris des enzymes, des anticorps, des acides nucléiques, d'autres polymères, des gels ou des membranes. On peut alors procéder à la fixation, et ce grâce à une simple adsorption par, ou une conjugaison covalente ou non covalente, avec la totalité de la surface (ayant subi l'ablation ou non). Après la fixation, on peut simplement détacher la couche protectrice (5), enlèvant ainsi le matériau de fixation de toutes les surfaces, à l'exception de la surface définie par la photoablation au laser ultraviolet. On laisse ensuite la surface obtenue dans un état chimiquement et géométriquement défini par l'exposition initiale au laser ultraviolet.

Abstract: A poker is provided for a packaging machine which has
a former (6) for bending a film into a tubular form and a
chute (7) for guiding articles to be packaged into a bag
being made below. The poker includes a driver link (23)
which is driven to undergo a reciprocating rotary motion
around a fixed axis (22a) and a generally L-shaped arm
member (24) disposed above and behind the former. A base
part (24a) of the arm member is rotatably connected with a
moving end part of the driver link (23) such that the arm
member can undergo a reciprocating rotary motion around a
mobile axis of rotation (27) which rotates around the
stationary axis of rotation. A connecting mechanism
(26,28) is further provided to coordinate these two
rotationally motions such that the tip of the arm member
distal from its mobile axis of rotation will move along a
desired trajectory to reach a desired bottom center part of
the chute which is likely to become clogged with the
articles dropped thereinto. The connecting mechanism may
be formed with a cam-following member (28) attached to a
part of the arm member and a cam plate (26) with an
elongated opening (26a) such that this cam-following member
is constrained to move along an arcuate path determined by
this elongated opening.

Date Jul. 16, 1998A refrigeration system having a closed circulating circuit filled with a refrigerant which on evaporation expands and gives rise to an increase in pressure in the whole or in parts of the circulating circuit, and which at ambient temperature has a saturation pressure that is higher than the maximum working pressure in the refrigeration circuit. A refrigeration of this kind may, for example, be carbon dioxide. By allowing vaporized refrigerant to condense against the surface of the refrigerant in liquid phase, contained in a container that is insulated and has adapted size and adapted liquid level, the pressure in the circulating circuit can be maintained below the maximum working pressure of the refrigeration circuit. Thus undesirable build-up of pressure in the event of, e.g., a period of inoperation or breakdown, is prevented, and the circulating circuit of the refrigeration system can be designed and made for a pressure which is below the saturation pressure at ambient temperature of the refrigerant used, and the refrigeration system can be made using conventional or at least virtually conventional elements, whereby the total system costs are reduced considerably in relation to a total system which is built to withstand higher pressure, e.g., the saturation pressure at room temperature of the refrigerant. Starting up after, e.g., a period of inoperation or breakdown is secured with valves which provide a controlled fall in pressure in an insulated container after an increase in pressure in the same container exceeding the maximum working pressure of the circuits.

Abstract: The purpose of the present invention is to present a thin-plate
magnet with a fine crystalline structure that is 70 µm to 500 µm thick,

inherent coercive force iHc of 2.5 kOe or higher and residual magnetic flux
density of 9 kG or higher and a performance-to-cost ratio rivaling that of
hard ferrite magnets when Nd-Fe-B fine crystalline permanent magnets
with a low rare earth content that are a mixture of a soft magnetic phase and
a hard magnetic phase are produced. iHc can be increased to 2.5 kOe or
higher and the optimum roll circumferential speed range within which hard
magnetic properties are realized can be expanded when compared to the
conditions under which Nd-Fe-B ternary magnets are produce, while at the
same time, a fine crystalline permanent magnet alloy with a thickness of 70
µm to 500 µm is obtained, by using an alloy melt with a specific composition
to which Co, Cr, Mn, Ni, Cu, Ga, Ag, Pt, Au, or Pb has been added during the
process whereby a fine crystalline permanent magnet alloy having a fine
crystalline structure of 15 nm to 50 nm is produced directly from an alloy
melt by continuously casting the alloy melt on a cooling roller that is
rotating in an inert gas atmosphere under reduced pressure of 30 kPa or less.

Abstract: L'invention concerne un récepteur (50) à erreur quadratique moyenne minimum (MMSE) pour systèmes à accès multiple par différence de code en séquence continue, fonctionnant sur des voies à évanouissement rapide. Le récepteur (50) de l'invention utilise les perfectionnements apportés au traitement standard (68) à moyenne quadratique minimale (LMS) dans la mise en oeuvre du récepteur MMSE pour augmenter la vitesse de convergence pendant l'apprentissage et la vitesse à laquelle l'algorithme peut suivre les changements d'états de voie. Ainsi, le récepteur (50) présente la même complexité linéaire, la même insensibilité à la régulation de puissance, la même temporisation et la même synchronisation de phase que les anciens récepteurs, mais il est également capable de fonctionner efficacement dans des conditions de voies plus difficiles et nécessite des périodes d'apprentissage plus courtes pour qu'une bonne convergence soit assurée. L'approche préférée, consiste à diviser la voie sujette à évanouissement en régions de quasi-stationnarité et à appliquer de manière répétée le procédé à moyenne quadratique minimale. Des grandeurs de pas multiples (W) sont utilisées en parallèle pendant les phases de retour de décision (64) et d'apprentissage (62), ce qui contribue à la convergence de l'algorithme LMS. Les régions dans lesquelles le récepteur ne fonctionne pas très efficacement sont repérées en tant que telles pour des phases de décision ultérieures ou sont retransmises sélectivement.
