The invention relates to a handle (e.g., a fixed handle, rotary handle, or swivel lever handle) particularly with a lock insert or the like or escutcheon for mounting in a preferably thin wall (e.g., a sheet metal cabinet door leaf, sheet metal drawer front, or sheet metal box lid). Wherein the handle has a longitudinal extension at whose ends is arranged at least one fastening means (e.g., a screw, nut, hook fastening or clip-in fastening). The lock insert includes a housing with a collar in the vicinity of its front end, and a receiving space for the front end of the housing with the collar is provided at this end of the handle in the vicinity of the fastening means proceeding from the contact surface contacting the thin wall, this receiving space passing through the handle to the front side of the handle while changing in cross section.
摘要:
A gas discharge lamp for the wavelength range of extreme ultraviolet radiation and/or soft X-ray radiation has at least two electrodes for providing a radiaton-emitting plasma in the intervening discharge space. One of the electrodes has a continuous opening to an adjoining outer region where charge carriers can be generated which can be transported through the opening in to the discharge space. The electrode opening narrows in the direction of the outer region.

In a method for generating extreme ultraviolet radiation or soft x-ray radiation by means of gas discharge, in particular, for EUV lithography, a discharge vessel is provided with two electrodes that are connected to high voltage. Between the electrodes, in an area of two electrode recesses that are coaxial to one another, a gas fill with predetermined gas pressure in accordance with a discharge operation realized on the left branch of the Paschen curve is provided. In this area, a plasma emitting the radiation is generated when supplying energy. The plasma is displaced or deformed by a pressure change of the gas fill in the area of the electrode recesses.
摘要:
A method and a device for generating extreme ultraviolet (EUV) and soft x-ray radiation from a gas discharge. The device has at least two electrodes each having a flush opening by which an axis of symmetry is defined, in which an intermediate space with a wide spatial homogenous gas filling between anode and cathode is provided. The electrodes are formed in such a way, that the gas discharge is formed exclusively in the volume defined by the flush openings. The current pulses with respect to amplitude and period duration are selected in such a way that a dense hot plasma channel is formed on the axis of symmetry, the plasma being the source of EUV and/or soft x-ray radiation. The preferred area of application is the EUV projection lithography in the spectral range around 13 nm.

A retractable hand lever actuator which can be locked in a trough for driving a latch for a switch cabinet or the like is described. The hand lever is articulated at a drive shaft supported in the trough. According to the invention, the hand lever actuator comprises a handle such as a T-handle or L-handle having two connection levers which are arranged relative to one another in a parallelogram configuration and which are articulated by one end at the drive shaft and by the other end in a similar manner at the handle in such a way that, on the one hand, they hold the handle in its direction parallel to the extension of the trough when the handle is folded out of the trough and, on the other hand, are able to transmit a rotational movement of the handle to the drive shaft in the folded out position.

A latch lock having a latch which is arranged so as to be displaceable against spring force in a lock case that can be fastened to a wall, door leaf, or the like, having a first locking cylinder whose thumb draws the latch back against spring force when the cylinder core is rotated by a key. The locking cylinder is constructed in such a way that it allows the key to be pulled out only in a determined position of the cylinder core with reference to the cylinder housing such as in the locking position. According to the invention, a second locking cylinder is arranged in the lock case and coupled with the first locking cylinder such that, when rotated by means of a key, its thumb moves the first locking cylinder into the determined position in which the key can be extracted from the first locking cylinder.

The invention relates to a gas discharge source, in particular for generating extreme ultraviolet and/or soft X-radiation, in which a gas-filled intermediate electrode space (3) is located between two electrodes (1, 2), in which devices for the admission and evacuation of gas are present, and in which one electrode (1) exhibits an opening (5) that defines an axis of symmetry (4) and is provided for the discharge of radiation. The proposed improvements constitute the presence of a diaphragm (6), which exhibits at least one opening (7) on the axis of symmetry (4) and operates as a differential pump stage, between the two electrodes (1, 2).

The invention relates to a gas discharge lamp for EUV radiation with an anode (1) and a hollow cathode (2), wherein the hollow cathode (2) has at least two openings (3, 3′) and the anode (1) has a through hole (4), which is characterized in that the longitudinal axes (5, 5′) of the hollow cathode openings (3) have a common point of intersection S lying on the axis of symmetry (6) of the anode opening (4).
摘要:
The novel process and device makes it possible to construct linear transfer installations without a special return transport system for workpieces or workpiece carriers, to keep the number of circulating workpieces or workpiece carriers to a minimum, and to increase or reduce the number of stations in the transfer installation in an arbitrary manner. The invention consists of organizing a flow of parts via an arbitrary number of successive stations by the alternating transfer in pairs between respective adjacent stations so that, as a result, a forward as well as a return movement of workpieces or workpiece carriers is produced. For this purpose, dumbbell-type double transfer devices are used between all stations, and alternate of the transfer devices are operated simultaneously to transfer the workpieces.
