Patent WO-9104513-A1 (WO)
Inventor: DE FORNEL FREDERIQUE
IPC: H01L21/027
Filed: 1990-09-21
Abstract: A method of direct microlithography by screening a substrate (2), such as silicon wafer, with an optical and/or electronic beam in order to photomecanically or electromechanically etch submicrometric structures on the surface of said substrate. The method is characterized in that the source of the optical and/or electronic etching beam is kept an appropriate distance away from the substrate by means of a proximity sensor with a waveguide, such as a fiber-optical proximity sensor (6), adapted to measure the rapid variations, according to said distance, in the intensity of an electromagnetic wave reflected by the substrate in the near field region located on the end (8) of said sensor. Microlithography devicces for implementing this method are also described.

Inventor: YVES PARVANCHERE
IPC: A23L21/12
Filed: 1990-11-27
Abstract: Le produit de l'invention est destiné à la confection rapide de confitures de ménage allégées, mais présentant des qualités de conservation analogues. Le produit contient typiquement, avec du saccharose, 1,6 % de pectine gélifiante, 0,4 % d'acide citrique anti-oxygène et 0,15 % de sorbate de potassium conservateur, à titre d'additifs. Le produit est un mélange macroscopiquement homogène de deux phases granulaires de granulométries analogues, une première phase entrant pour un poids de 75 à 80 % du mélange et constituée de cristaux de saccharose pur de tailles sensiblement uniformes et une seconde phase formée de grains à composition sensiblement régulière d'un agglomérat des additifs avec du saccharose en poudre. Il est indispensable que les teneurs en additifs soient maintenues dans des fourchettes étroites pour être efficaces sans risques de surdosages. L'homogénéité du produit de l'invention provient de ce que d'une part, l'apport d'additifs au saccharose se fait par deux mélanges successifs, et d'autre part les deux phases du mélange ont sensiblement même granulométrie.

Title: Antideflagrating and antifoaming method of transferring a fluid using an immersed interactive metering pipe
Inventor: ADRIEN HILLION
IPC: B67D7/00
Filed: 1991-01-08
Abstract: The method allows the accurate metering and filling of tanks in which the neck acts as a support for the sliding and lockable flange (7) of a pipe (5) fitted with a sensor (3) which detects the upper level of the fluid and, once this level has been reached, generates a signal to automatically close the operating valve (2), the opening of which can be triggered manually or by the control system. The combined effect on the fluid of its exiting laterally through the apertures (17), of the braking action of the rim (19) of the apertures, of the damping cavity (18), of the partly conical profile (24) of the movable shut-off member (20) fitted with decompression grooves (23), is superimposed on the interactive action of the walls of the tank, in order to make the method an antifoaming one. Enclosing the sensor in an insulator (16), covering up the sensor with the movable shut-off member and distancing the assembly from the equipment plant, make the method an antideflagrating one. The method concerns manufacturers, packagers, dealers, users, laboratories or factories handling highly reactive (hazardous, corrosive) or sensitive fluids.
