There is provided an illumination system for microlithography with wavelengths .ltoreq.193 nm. The illumination system includes a primary light source, a first optical component, a second optical component, an image plane, and an exit pupil. The first optical component transforms the primary light source into a plurality of secondary light sources that are imaged by the second optical component in the exit pupil. The first optical component includes a first optical element having a plurality of ...

Revolver firearm comprising a body divided in an upper part, or slider, comprising a barrel and a drum, slidingly associated with a lower part, or case, comprising a handle, a trigger and a hammer; a first kinematic chain arranged in said case for arming the hammer; a second kinematic chain, arranged in said slider, and adapted to cause the rotation of the drum and to successively align the firing chambers of the drum with the barrel, the first and second kinematic chains being selectively activ...

Microscope, particularly a stereomicroscope, for simultaneous observation by a first and a second observer, comprising a main objective (2) defining an optical axis (2a) and an optical beam path (17) following a direction of the optical axis (2a); a magnification system (12, 13) mounted after the main objective (2); a beam splitter device (5) mounted after the main objective (2) for deflecting a first partial optical beam path (17a) into a first plane (I) of the microscope, and for transmitting ...

A housing, particularly of a vehicle headlamp, has aeration of its interior housing space via at least one hole for admission and/or exiting of air flows, wherein a switch apparatus, that changes a cross section of flow as a function of humidity of the air, is positioned in the at least one hole to move automatically from a closed position into an open position and vice versa. A method for aerating the interior space of the housing involves air entering the interior housing space via at least on...

A multilumen catheter (1) of a type comprising two inner lumens (2, 3) defined by a wall (2A, 3A) for guiding a fluid (4), and two opposite ends (5, 6), namely a distal end (5) and a proximal end (6), characterized in that the distal end is formed of two elongated and discrete end portions (13, 14) located beyond a so-called dividing point (12) at a predetermined distance D1 from the proximal end (6), wherein said end portions, in a rest position of the catheter, extend parallel to the longitudi...

A collective holder, in particular for keys, having a holder housing (1) of flat configuration with a cornerless outline whose circumferential narrow side wall forms a running rail (2) with a removal opening, operable by a grip from a broad side wall, for runners (3) captured in the running rail (2). The collective holder provides an outline contour deviating from the circular and has two opposite, approximately semicircular arc segments (A, B) whose apexes (A', B') are spaced apart by approxima...

Braking device, particularly usable for skates including a shoe composed of a quarter which is articulated to a shell which is in turn associated with a frame for supporting wheels. The device includes at least one cable which connects the quarter to a braking element, so as to allow to obtain the braking action when the quarter is tilted.

An innerboot, particularly for sports shoes, made of thermoformable material, includes, at its inner lateral surface, one or more channels advantageously connected to the outside through one or more holes, the innerboot allowing ventilation of the foot arranged inside the innerboot, improving user comfort.

A reflector body for flashcubes containing mechanically ignitable flashbu, said reflector body having a base edge length of .ltoreq. 25 mm and a ratio of base edge length to lateral edge length of .gtoreq. 1 and forming four individual reflectors. The individual reflectors are formed by two planes forming a right angle and by a cylindrical area interconnecting the two planes. At the top end, the plane reflector areas merge across cylindrical and spherical areas into triangular cover planes, at t...
