An etching composition and a method utilizing such a composition for etching a surface of a polyimide is disclosed. The method comprises exposing the polyimide surface to an etching composition comprising an aqueous solution of a basic compound and ethylene diamine. The ethylene diamine synergistically increases the etching rate of the polyimide. When the ethylene diamine is present in an amount in excess of its degree of solubility the etching of the polyimide results in a frosted or matte fini...

A method of blocking microbial adherence to a eukaryotic cell surface in a mammal by applying a pharmacologically acceptable composition containing at least one compound selected from the group consisting of isoleucine, an active isomer thereof, and an active analog thereof, to said surface in a microbial blocking quantity. Also, compositions for achieving the above blocking of microbial adherence.

A phase change material is formed over a dielectric material. An impurity is introduced into the dielectric to improve the adherence of said dielectric to said phase change material.

A clamping device, especially for pistons of internal combustion motors, permitting previous indexing and ensuring the handling and maintenance in position of the said pistons during the half-finish and finish machining operations of the skirt and the lands of said pistons. The device comprises a receiving member in frontal support of the head of a workpiece, presenting, centering and indexing members for the piece towards the said receiving member, and members intended to apply the piece agains...

The present invention provides specific peptides identified as having cell adhesion, growth, expression or secretion-enhancing activities. Many of the peptides of the invention may be produced in large quantity by such means as chemical synthesis or recombinant DNA methodology. They may be non-specifically adsorbed, or chemically attached to a surface or, alternatively, formulated in a culture medium to produce the desired effect on cultured cells.

In a method for magnetic resonance imaging with adherence to SAR limit values, a patient is charged with a radio-frequency pulse sequence via at least one transmission antenna for the implementation of a measurement in a magnetic resonance tomography apparatus, and the magnetic resonance signals that are produced are acquired in a spatially resolved manner via at least one reception antenna and are further-processed for producing magnetic resonance images or spectra. SAR values are determined be...

A binding unit binds sheets with a binder having an electric heater and electrodes for supplying electric current to the electric heater. The binding unit includes a container and an inner lid. The container has an insertion opening at one end through which the binder is inserted, and electrode terminals at the opposite end which come into contact with the electrodes of the binder. The inner lid is openable and provided in the container between the insertion opening and the electrode terminals. ...

A method for determining the degree of adherence to a non-flat, opaque vehicle panel surface of a component adhered thereto. The method includes providing an integrally cast clear matched surface in the panel so that the contacting surfaces of the component may be directly viewed.

An application of dendritic nickel particles to a nickel containing cathode substrate to form a porous nickel is filled with potentially emissive material in one or more alternate spray passes. The nickel particles are welded to the substrate and to each other at the time the cathode is activated at a temperature in excess of the sintering temperature but below the melting temperature of the nickel particles. The procedure eliminates a separate sintering step and provides excellent adherence of ...

A process for protecting vehicle windshields and chrome-plated, painted and other vehicular surfaces with a coating which prevents adherence of insects impacting with such surfaces and any chemical reaction of bug remains therewith. The coating is water soluble and contains an oil barrier, surfactant, hydrophilic agent and lipophilic agent, among other ingredients. The impacted insect remains are easily removable by washing off the coating with water.
