A mask for shifting a phase used in a photolithographic process of forming a wiring pattern. A pattern (12) for blocking light is formed selectively on a transparent mask substrate (11). Also, two kinds of shifters (13a, 13b) are provided at transparent parts adjoining to the pattern for blocking light. The difference in phase between the shifters and the transparent mask substrate are both 90 DEG...

The invention concerns a micropowder with spherical particles having an essentially smooth surface structure and containing as the essential component polyarylene ether sulphones or ketones and obtained by prilling melts of such compounds or by spray-drying solutions thereof.

High elasticity foams can be prepared from a reprocessable blend of a thermoplastic vulcanizate and an elastic thermoplastic polymer. These foams can be mechanically foamed with water and can have elongations to break in excess of 250 percent. They also have recovery of that elongation also known as low permanent set.

A brake actuator for use on passenger transit railway vehicles. The actuator includes a housing containing a service piston and a parking brake piston. The service piston is connected to an inner hollow stem having a forward conical surface disposed to engage a conical surface of a collet provided on a threaded rod located within the stem. The parking brake piston has a hollow outer sl...

An outer tube for housing a double-ended needle in a manner to be vertically slidable is air-tightly and detachably connected and fixed to a seal portion at the mouth portion of a vessel containing therein a solution, an inner tube for housing therein an inverted vial containing therein drug is connected to the top end of the outer tube in a manner to be movable from a shallow fitting position to ...

The present invention relates to a pallet comprising first and second base parts (A1 and B1), each folded from pieces of corrugated, waterproof fiber material, for instance paper. Rectangular pieces (A, B) are cut from rolls of fiber material and the two base parts are made by notching and folding the pieces according to separate sequences. The first base part (A1) is put into the second base part...

The present invention relates to the formation of a macrocomposite body by spontaneously infiltrating a permeable mass of filler material or a preform (4) with molten matrix metal (2) and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body and/or a metal or metal containing body. Particularly, an infiltration enhancer and/or i...

Continuous production of a panel, partic. a mineral wool insulation panel; covered or at least two adjacent faces from a continuous band consists of the following operations all carried out at the same line speed or the moving band: (a) Sticking the covering (2) on a first face of the band; (b) Maintaining the covering in position until the bonding is complete; (c) progressively folding the coatin...

A suspension-type grouting liquid for injection into a ground having excellent penetration properties, e.g. low viscosity and long gelation time, and having comparatively high strength after consolidation. The suspension-type grouting liquid for injection into a ground consists essentially of slag, or a combination of slag and cement, alkali metal aluminates, and water. The slag is a fine grain ha...

A suspension-type grouting liquid for injection into a ground includes sodium aluminate having a mol ratio of 10 or more; and slag, wherein the mol ratio of sodium aluminate is defined as molar concentration of Na2O/molar concentration of Al2O3. Preferably, the slag is fine grained and has a specific surface area of 8000 cm2/g or more. The grouting liquid may further include at least one additiona...

The disclosure relates to a method of producing interiorly sterile, cup or beaker shaped containers. A starting material for the containers is produced by mixing inorganic filler with a thermoformable polymer material in such a mixing ratio that the quantity of filler in the produced starting material is at least 40% of the total weight of the mixture. The starting material is extruded into a cont...
