Title: Low dielectric loss glasses
Inventor: THALER BARRY JAY
IPC: H01L23/15
Filed: 1996-01-29
Abstract: High magnesium-content magnesium aluminosilicate glasses are used to form green tape compositions that are fired stepwise, i.e., first to about 500 °C to remove organic materials, then to a temperature 10-30 °C above the glass transition temperature for a time sufficient to nucleate the glass, and finally to a higher temperature near but below the softening temperature to complete crystallization of the glass.  The resultant glass-ceramic may include substantial amounts of the forsterite crystalline phase. Multilayer ceramic printed circuit boards are made that are useful for high frequency, microwave applications. The fired high magnesium oxide content glasses have low dielectric constant and low dissipation loss factors, and they have a thermal coefficient of expansion that is compatible with metal or ceramic support substrates that impart mechanical strength to the printed circuit boards and that are thermally conductive. The boards are compatible with gallium arsenide devices.

IPC: F28D9/00
Filed: 1996-10-02
Abstract: L'invention porte sur un échangeur de chaleur à matériau pelliculaire et sur son procédé de fabrication. Cet échangeur de chaleur comprend, d'une part des sacs (1) faits d'un matériau pelliculaire avec pour but de transférer de la chaleur provenant de vapeur à condenser dans les sacs vers un liquide à évaporer sur les faces externes (18) de ces sacs et, d'autre part des rangées de canaux d'alimentation destinés à répartir la vapeur (10) et le liquide sur les faces interne et externe de transfert de chaleur des sacs. Selon cette invention, l'extrémité sommitale intérieure (2) de chaque sac (1) est pourvue d'une bande sensiblement droite (11), en bordure des canaux destinés à la vapeur (10), bande à laquelle le sac est fixé. En relation avec cette opération, une traction rectiligne est exercée sur le bord supérieur du sac du fait du cintrage du sac, de sorte que la partie médiane du sac s'élève par rapport à ses cotés (12). Le bord ainsi redressé est alors attaché à la bande installée à l'intérieur du sac. Il est possible, respectivement, de couper le bord du fond (3) du sac pour le rendre concave vers le haut et de le fixer, après ce redressage, à une bande (15) adaptée à l'extrémité interne du fond du sac et comprenant des canaux d'élimination (14) de condensat. Lorsque les bords du sommet (2) et du fond (3) du sac se redressent, des plis horizontaux (13) se forment dans le matériau pelliculaire, servant de marge de gonflage tout en mettant le sac sous pression.
