Abstract: A method for fabricating an IC module (1) including a resin packaging step conducted by using top and bottom forces (5) defining a cavity (50) in a clamped state, wherein the packaging step comprises placing a substrate (2) on which an IC chip (3) is mounted and a winding coil (20A) having a doughnutlike planar shape and a flat overall shape in a cavity (50) and injecting a molten resin into the cavity (50). When resin packaging is conducted on a substrate (2) on which an antenna coil (20) is patterned, spacers (28) having a height equal to or substantially equal to that of the cavity (50) are provided on the substrate (2), which is then placed in the cavity (50) and packaged by injecting the molten resin. Alternatively, the substrate (2) in the cavity (50) may be vacuum-clamped. The IC chip (3) and the antenna coil (20) can be well protected by such a method.

Title: Pressure casting of battery terminals
Inventor: RATTE ROBERT W
IPC: B22D17/14
Filed: 1999-10-08
Abstract: ABSTRACT OF THE DISCLOSURE A closed system and method that includes a source of pressurizeable molten lead connected to a mold having a mold cavity therein with the mold maintainable at sufficiently low temperature so that a charge of molten lead located in the mold cavity solidifies to thereby form a solidified casting in the mold cavity. A housing having a runner, is maintainable at sufficiently high temperature to maintain the molten lead in a molten state so that the mold cavity can be refilled with a fresh charge molten lead when a solidified casting is removed therefrom without introducing air to the closed system. A shut-off valve, having an open position to allow a charge of molten lead to flow into the mold cavity and a closed position to prevent molten lead from flowing out of the runner as the molten lead in mold cavity solidifies with the shut-off valve configurable to intensify the pressure of the lead in the mold cavity. The intensification mode being monitorable so that when the state of molten enters a liquid-to-solid transformation stage, the volume of the mold available for the lead to solidify therein is quickly reduced through a volume contraction step to thereby cause the molten lead to flow into the remaining volume at the same time one maintains pressure on the molten lead. As the molten lead solidifies under the reduced volume and high pressure it produces a battery part that is substantially free of both tears and cracks. In an alternate intensification method, the lead is allowed to solidify and at least a portion of the lead is mechanically deformed through a volume contraction step to cause cracks or tears in the battery part to be eliminated thereby providing a battery part free of cracks or tears. In another method of forming a pressure cast battery part free of cracks a molten lead under pressure is flowed into a battery part cavity and the pressure of the molten lead is increased to sufficiently high pressure so that when the molten lead solidifies it forms a battery part free of cracks and voids.

IPC: H04L12/14
Filed: 1999-04-28
Abstract: A message is provided to a tracking server system in response to a client system referencing a predetermined resource locator that corresponds to a resource external to the tracking server system. The tracking server system indirectly provides for the client system to have an informational element selectable by the client system, where the informational element is graphically identified on the client system with informational content obtainable from a content server system through use of a content resource locator. The informational element includes a tracking resource locator, referencing the tracking server system, and data identifying the informational element. The selection of the informational element causes the client system to use the tracking rersource locator to provide the data to the tracking server system and to use the content resource locator to obtain the informational content from the content server system.

Abstract: L'invention traite d'un procédé et d'un dispositif microfluidique permettant de séparer une matière recherchée, par exemple un acide nucléique, d'autres matières contenues dans un échantillon fluide. Selon un mode de réalisation préféré, ce dispositif comporte une microplaquette (20) dotée d'un orifice d'entrée (28), d'un orifice de sortie (30) et d'une chambre d'extraction (26) en communication par voie de fluide avec ces orifices. Cette chambre (26) possède des surfaces de fixation internes destinées à capturer la matière recherchée de l'échantillon fluide au fur et à mesure que celui-ci s'écoule de manière continue dans ladite chambre. La matière capturée peut ensuite être éluée en forçant l'écoulement d'un fluide d'élution dans la chambre (26). Ce fluide libère la matière des surfaces internes et provoque son passage dans le fluide d'élution. L'écoulement continu qui caractérise ce dispositif permet à la matière cible issue d'un volume relativement important d'échantillon fluide d'être concentrée dans un volume beaucoup plus petit de fluide d'élution. Lesdites surfaces internes sont de préférence formées d'un réseau de colonnes (32) intégrées à la paroi de la chambre (26) et s'étendant dans cette dernière. Ces colonnes (32) assurent une large surface de capture de la matière recherchée. Ce dispositif comporte de préférence un chauffage (34) destiné à augmenter l'efficacité de l'élution.
