Patent EP-0120054-B1 (EP)
IPC: A61N5/06
Filed: 1983-09-09
Granted: 1990-05-30
Abstract: A method of synthesizing and purifying a high molecular weight aggregate, derived from hematoporphyrin, said material being useful in the localization and treatment of tumors. The substance results from the hydrolysis of the reaction mixture of hematoporphyrin and acetic-sulfuric acids. The material is purified by cycling the crude product through a micro-porous membrane system in which exclusion of low molecular weight by-products is effected. The substance is tumor-selective and photosensitizing. It is retained in tumors longer than in normal tissues and fluoresces red to aid in diagnosis. Strong illumination of tumors retaining the substance results in necrosis, while normal tissues which have generally eliminated the drug remain unaffected. The high molecular weight aggregate has an empirical formula of approximately C68H70N8O11 (Na plus H)4.

Abstract: Procédé de prétraitement d'une tranche semiconductrice de manière à appliquer directement un rabattement de protection positive d'une solution d'anhydride polyméthacrylique sur la surface traitée. Une tranche semiconductrice typique en silicium est d'abord prérevêtue d'une fine couche de poly(t-butyl méthacrylate) puis chauffée pour convertir le poly(t-butyl méthacrylate) en anhydride. L'épaisseur de cette couche précurseur de l'anhydride est inférieure à 1000 angstroems environ. Ensuite, on applique sur la surface de la couche précurseur une solution d'anhydride polyméthacrylique dissous dans, par exemple, le diméthylacétamide, le diméthylformamide, ou N-méthyl-pyrrolidione. De tels solvants, incapables de mouiller de manière adéquate et directement la surface de silicium, sont capables de mouiller la couche précurseur comprenant l'anhydride polyméthacrylique, assurant ainsi un dépôt uniforme d'anhydride polyméthacrylique sur la surface traitée de la tranche. Après application de la solution sur la tranche traitée, le solvant est enlevé par évaporation pour former une couche uniforme d'anhydride polyméthacrylique déposé de la solution et ayant une épaisseur de l'ordre de 2.000 angstroems à 20.000 angstroems environ.

Abstract: An input buffer circuit (10) having a single input for receiving input voltage (VIN) characterized by having varying voltage swings. First (12 and 15) and second (16 and 18) inverter circuits having differing switchpoint voltages are coupled to a level shifting portion (13, 17). The level shifting portion varies the level of swing of the input voltage (VIN) and buffers the input voltage (VIN). In one form, voltage coupling circuitry (22, 23) is interposed between the level shifting portion and a latching portion (25, 26) which provides the input voltage (VIN) as an output signal at a predetermined voltage level. In another form, voltage coupling circuitry (48, 53) controlled by control circuitry (49, 50, 57) couples the output of the level shifting portion (43, 44) to an output in response to the input voltage (VIN).

Abstract: In an electrical device comprising first and second members having different resistivities, a thin contact layer of intermediate resistivity is provided between the first and second members. The contact layer, (which may comprise a conductive polymer) is intimately bonded to the member of highest resistivity (which may comprise a second conductive polymer) e.g., by a printing process. The member of lowest resistivity may comprise a third conductive polymer, in which case it may be intimately bonded to the intermediate contact layer, e.g., by a printing process, or it may comprise a metallic member, in which case good electrical contact may be made merely by pressing the metallic member against the contact layer even when the contact area is large and/or long, and even when the pressure is sufficiently low to permit, if necessary, relative movement of the metallic member and the contact layer without disrupting the bond between the contact layer and the resistive element. A preferred device comprises four or more members of different resistivities. The members are arranged adjacent each other in order of decreasing resistivity. The least resistive member preferably comprises a metal and the other members conductive polymer materials.

Abstract: At least one string of several spaced measuring probes for the measurement of surface potentials is laid on the surface of the earth in such a manner that several probes are located outside and several probes are located inside the area of the surface over a reservoir. The potentials measured by all probes are polled in a sequence of periodic cycles. The signals from each probe are, during each cycle, filtered to separate higher-frequency changes in the signals from substantially lower-frequency changes in the signals. For the higher-frequency changes in the signals from each probe, an average and/or a sum are determined as a measure of the higher-frequency amplitudes for each probe. The higher-frequency amplitudes for the probes of a string of measuring probes are compared and the location at which the higher-frequency amplitudes for two adjacent probes change abruptly is taken to be the hydrocarbon/water interface in the underground reservoir.

Abstract: A method for the transmission of a video signal, in which the analogue signal is converted into a digital signal and is digitally transmitted. However, before the transmission is transformed into the spectral domain, some portions of the digital signals are variously weighted on the basis of the physiological behavior of the eye. This weighting is performed by coding the signals to be transmitted in their representational accuracy.
