Abstract: In such a mask, a support layer (2) for a structure (8) is mounted in a supporting frame (1). Mounting the support layer (2) in the supporting frame (1) may, however, result in stress components which produce a distortion of the support layer (2), thereby impairing the dimensional accuracy of the structure (8). To ensure the dimensional accuracy of the structure (8) if stress components occur, the support layer (2) has, in the peripheral region (9) between the structure (8) and the supporting frame (1), an elastic region (10) which is formed by two rows of mutually offset perforations (11) which surround the structure region (7) with the structure (8) and consequently isolate the structure region (7) from the stress components originating from the supporting frame (1). The irradiation mask is used, in particular, to produce optical gratings and also semiconductor devices by X-ray lithography or ion lithography (Figure 1). …<IMAGE>…

Abstract: A method and apparatus whereby a reactive polyurethane mixture (24) is fed into the upwardly open door backing panel (1) while this rests on a profiled mould support (10), to form a soft or elastically yieldable expanded polyurethane mass. The outer metal wall (2) of the door is then superposed on the door backing panel (1) without removing the door backing panel from the mould. The assembly formed from the outer metal wall (2) and door backing panel (1) defines an empty compartment (30) into which a reactive polyurethane mixture is injected to produce a non-elastically yieldable expanded polyurethane mass which forms the thermal insulation. This injection takes place while said assembly is disposed together with the mould (10) between two counteracting surfaces (11, 17).

Abstract: A bearing assembly and a bearing retaining member for such an assembly includes a bearing 3 for a shaft 1 mounted in a seating 8 of a housing 2. The bearing 3 is retained axially in its seating by abutment with a flat, planar spring retaining member 11 having arms 13 which extend radially outwardly and circumferentially in curved or spiral profile from a centre ring 12. The arms 13 flex radially to snap engage in an internal annular recess 10 in the housing 2. The arms 13 have arcuate side edges 15 which engage in annular recess 10 and correspond to the diameter of that recess. The engagement of the arms 13 with the recess 10 provides a wedge action which biases the member 11 axially into abutment with the bearing 3. In a modification the arms of the retaining member extend radially and circumferentially inwardly from an outer ring of that member for snap engagement with an external annular recess on a shaft to retain a bearing axially on that shaft.

Abstract: A method of manufacturing integrated circuits using holographic techniques by interference between an input beam (S) and a reference beam (R) generated from laser sources (24,25). A holographic image of the object formed on a mask window (19), is formed on recording emulsion coated on a glass slab (16) by means of interference between the input beam (S) which has passed through the mask (18) and the reference beam (R) which is reflected from the surface (X) of a prism (22) in contact with the glass slab (16). In order to reproduce the holographic image on a silicon slice which replaces the mask (18), the reference beam is replayed in the reverse direction through the prism (22) such that the interference between the input beam (S) and the replayed reference beam (R) causes the holographic image to be created as a real image in the silicon slice.

Abstract: A method for creating population inversions for use in stimulated emission devices which beam combine, beam clean-up, or frequency up-convert electromagnetic radiation. The invention comprises near resonantly enhanced multiphoton pumping of a multi-level quantum medium with pump beams of appropriate intensities and frequencies detuned from the transition frequencies of the medium. The intensities are orders of magnitude lower than those required for non-resonantly enhanced multiphoton pumping. The detuning is smaller for the maximum multiphoton resonance than for the single photon resonances. Appropriate medium decay constants are required for creating a population inversion between energy levels of the quantum medium. The population inversion exists between energy levels of the medium whose energy difference may exceed the energy of any single pump photon energy. The appropriate energies, detunings, intensities, and decay constants are determined by analysis of the semiclassical densities matrix equations for the multi-level quantum medium. The energy extracted from the population inversion may be at a frequency nearly equal to or greater than the pump frequencies.

Abstract: A circuit breaker in which the levels of overload currents are detected with increased accuracy and which functions properly even just after its load-connecting contacts are closed. A rectifier circuit (30) converts outputs from current transformers (21, 22) into currents flowing in one direction, the current transformers (21, 22) detecting the currents through the main paths (11, 12). A power supply circuit (500) and current-detecting resistors (40, 41, 42) are connected in series with the output of the rectifier circuit (30). Differential amplifiers (60, 61, 62) amplify the potential differences across each resistor (40, 41, 42). If the power from the power supply circuit (500) is insufficient to operate the differential amplifiers (60, 61, 62) and a timer (70) normally, an inhibiting circuit (50) prevents a switch circuit (120) from being closed.

Abstract: We describe an integrated thermal ink jet printhead and manufacturing process therefor which includes the successive build-up of an orifice plate (18), a first barrier layer (20), heater resistors (22), a second barrier layer (30), and an ink reservoir-­defining layer (38) on top of a reusable or "dummy" substrate (10). Lead-in conductors (24,26,28) are formed integral with the heater resistors (22) by controlling the cross-sectional areas of these components, and openings (44,46) (passageways) are formed between ink reservoirs (40,42) and the orifice plate (18) to provide for ink flow under control of the heater resistors (22). The dummy substrate (10) is stripped away from the adjacent orifice plate (18), and the ink reservoir defining layer (38) may be secured to an ink supply tank (48) which supplies ink to the individual ink reservoirs (40,42). Thus, the orifice plate (18), heater resistors (22) and ink flow paths (44,46) of the printhead are self aligned, and the heater resistors (22) are removed or displaced from direct cavitational forces from ink ejected from the orifice plate (18).
