Semicrystalline polymers can have predetermined amounts of their surfaces rendered quasi-amorphous by irradiation. Polymer surfaces which are so modified can display enhanced ability to accept bonding to other materials, particularly adhesives.

A process of immobilizing environmentally noxious organic, particularly aromatic, substances by absorbing same on a layered clay mineral modified by exchange with a quaternary ammonium compound, thereby increasing the spacing between the layers and rendering the adsorption surfaces hydrophobic. After adsorption of the organic compounds the spacing between the layers of the layered clay mineral is ...

A photosensitive composition wherein the setting is prevented in the presence of air is subjected to partial setting by exposing the side in contact with air to light, then to complete setting by radiating light again without contacting the unset part with air. The composition is extended on a metal surface and subjected to setting, hence the smoothness is excellent. In addition, after the unset p...

A computer aided software engineering tool is disclosed which is particularly well adapted to identify potential Assembly language source code errors resulting from incorrectly used symbolic and literal address constructs. This objective is achieved by providing a debugging program which has a complete awareness of the specific machine interfaces, conventions and symbol sets. By essentially steppi...

A porous metal coated implant is produced by diffusion bonding metal powder particles, preferably spherical or flattened spherical metal powder particles of commercially pure titanium grade, in the form of an insert or pad to a substrate, preferably commercially pure titanium or Ti 6Al-4V ELI, a prosthesis, below the beta-transus of the substrate material, under pressure and temperature in a non-r...

A retaining member (34) comprised of a retaining bracket (36) and a securing bar (38) operable to be disposed in the container (10). The retaining bracket (3...

A process for the consolidation of discrete, particulate, low-melting or liquid materials, characterized in that said materials are consolidated in their particulate discrete form by application of vapours of at least one p-xylylene monomer and/or of a derivative thereof, which is polymerized under vacuum. By such way, the materials are given the surface characteristics of a solid, with enhanced r...

A data processor which has instructions of operation and comparison when including the signed binary number represented by complement on 2 as the object and has a flag correctly representing the result of the operation as positive or negative regardless of whether or not overflow occurs so as to correlate the arithmetic operation close with a status flag change, thereby facilitating mathematical i...

A set associative type cache memory incorporated in a microprocessor includes memory arrays arranged in a group for each line, and only a memory array selected by a line address selected at the time of operation is made operative, thus reducing power consumption.

An improved composite material is produced by mixing ground gypsum and a plurality of host particles, each having accessible voids therein, together with sufficient liquid to form a dilute slurry; heating the slurry under pressure to a temperature sufficient to calcine the gypsum to calcium sulphate hemihydrate; allowing the calcium sulphate molecules to nucleate and form crystals in-situ in and a...

The Present invention provides a microwave irradiating sterilization process in which local irradiation is repeated by means of local heating waveguides being close to the undermentioned package in the case where either such a package charged with a material to be sterilized and then sealed hermetically or a supporting holder containing the package is irradiated with microwave while conveying cont...

8. The present application is directed to a package material for microwave cooking which is obtained by integrally laminating a microwave heating element, which generates heat when irradiated with microwave, to a base material to form a sheet; and providing, on the sheet, many slits in the form of broken lines, in parallel, and in alternation between the adjacent ones.

The present invention provides a method and apparatus for removing floating, substantially immiscible liquids such as hydrocarbons from containers or wells containing both floating liquids and water. In one aspect of the invention, a microprocessor control receives and processes input signals from a liquid sensor, an upper water interface sensor and a skim pump. The skim pump is located in the wel...

This invention discloses a particle separator adapted for use in a pressurized lubrication system for mechanical drives to separate debris particles from the fluid. Fluid tangentially injected into the housing impinges on the inner cylindrical wall in a manner which develops a downwardly directed spiral flow pattern, which generates a centrifugal force which firstly causes the entrapped gases to c...

An external skin care preparation comprising a compound represented by the following general formula (I) or (II), or a salt thereof: wherein R<1> means an aliphatic hydrocarbon group having 9-25 carbon atoms, A and B denote specific groups respectively, R<6> and R<7> are individually an aliphatic hydrocarbon group having 10-26 carbon atoms, and R<8> denotes a group -CH2CH2OH, -CH2COOH or -C...

A novel antitumor antibiotic of formula (I) designated BMY-41339 is produced by fermentation of certain strains of Actinomadura verrucosospora. BMY-41339 exhibits antimicrobial activity and also inhibits the growth of tumors in experimental animals. 1

The invention is a method for using 1-( beta -D-arabinofuranosyl)-5-propynyluracil or its salts as the active ingredient in pharmaceutical compositions in the treatment of varicella zoster viral infections whether expressed as chicken pox or shingles.

Oxetanocin derivatives represented by formula: wherein X represents H or or a pharmacologically acceptable salt thereof exhibit an anti-viral activity. Anti-viral compositions comprising the oxetanocin derivatives or their pharmacologically acceptable salts as the effective ingredient are also provided.

Cytorhodin S derivatives, especially cytorhodin S-immunoglobulin complexes are disclosed. Cytorhodin S possesses very high anticancer activity, but the complexes act more selectively on cancer cells and are more useful as an anticancer agent. New intermediate derivatives are also useful as an anticancer agent.

A one or two dimensional integrated array of multiple-wavelength, vertical-cavity lasers and its method of making.
