Patent EP-0502578-A1 (EP)
Inventor: VAN EIJK JAN
IPC: G03F9/00
Filed: 1992-02-28
Abstract: An optical lithographic device having a machine frame (1) to which is fastened a lens system (11) having a vertical optical main axis (13). Below the lens system (11), a positioning device (35) is fastened on a support member (3) of the machine frame (1), by means of which device an object table (27) is displaceable relative to the lens system (11) over a guide surface (5) of the support member (3) extending perpendicular to the optical main axis (13). 
     The device is provided with a force actuator system (67) fastened to a reference frame (83) and controlled by a feedforward control system (95). The force actuator system (67) exerts a compensatory force on the support member (3) with a direction opposite to a direction of a reaction force simultaneously exerted by the positioning device (35) on the support member (3), and with a value which is substantially equal to a value of the said reaction force. The control system (95) further comprises a negative acceleration feedback (107), whereby the force actuator system (67) exerts a control force on the support member (3) which is determined by an acceleration of the support member (3) measured by an acceleration transducer (111, 113, 115). The use of the force actuator system (67) prevents undesirable movements of the support member (3) under the influence of a reaction force exerted by the positioning device (35) on the support member (3) and under the influence of external forces. 
     The optical lithographic device can be used  inter alia  for illuminating semiconductor substrates, where a semiconductor pattern provided on a mask (17) is imaged on a semiconductor substrate (25), which is positioned on the object table (27), by means of the lens system (11).

Abstract: A method is provided for sulfonating an acyloxy substituted benzene ring to obtain high yields of desired sulfonated compounds that are useful as cleaning, bleaching, or fabric treating additives. A particularly preferred additive so prepared has the structure
       
 where R⁷ is a branched or unbranched alkyl with about 5 to 9 carbons and M is an alkali metal, an alkaline earth metal, or ammonium. The benzene ring is sulfonated by contacting with a molar excess of sulfur trioxide source and then irreversibly reacting the sulfur trioxide excess with a quenching agent. A neutralization process for preparing peracid precursors in high yield by neutralizing sulfonated aryl esters is also provided.

Abstract: A helmet (10) has a visor (12) mounted on pivot posts (18) fixed to the helmet. A visor driving and latching mechanism (24) acts both to allow the wearer to move the visor (12) between its lowered and raised positions and also to hold the visor in either position. The mechanism (24) has an operating lever (22) which is pivoted to the visor (12) at a point (30) spaced from the pivot post (18). The operating lever (22) has a slightly elongated aperture (28) which receives the pivot posts (18), and a hollowed out portion (32) which receives a cam (38) fixed in relation to the pivot post (18). The operating lever (22) has a first tooth (36) which engages in a first recess (44) in the cam (38) to hold the visor (10) in its lowered position, and a second tooth (34) which engages in a second recess (42) in the cam (38) to hold the visor (12) in its raised position. To move the visor (12) from its lowered to its raised position, the wearer manually rotates the operating lever (22) in the appropriate direction. Initial rotation of the operating lever about its pivotal connection (30) to the visor (10) withdraws the first tooth (36) of the operating lever (22) from the first recess (44) in the cam (38), to release the visor (10). Further rotation of the operating lever (22) rotates the visor (10) about the pivot post (18) until the second tooth (34) reaches the second recess (42) in the cam (38), whereupon the operating lever (22) rotates about its pivotal connection (30) to the visor (10) so as to move the second tooth (34) into the second recess (42), to latch the visor in the raised position. Similarly, to move the visor (10) to its lower position, the wearer rotates the operating lever (22) in the opposite direction, to disengage the second tooth (34) from the second recess (42), to then rotate the visor (10) to the lower position and to move the first tooth back into engagement with the first recess (44). The cam (38) has compliant projections (60 and 61), a respective one of which is engaged, in each of the lowered and raised positions of the visor (10), by the tooth (34) or (36) not engaged in the corresponding recess (42 or 44) in the cam (38), and which must be compressed during the initial movement of the operating lever (22), to inhibit inadvertent release of the latching engagement of the other tooth in the recess. The helmet may be provided with twin visors, each visor having its own driving and latching mechanism, the two mechanisms being located on opposite sides of the helmet.

Abstract: A streak retinoscope has an external control sleeve (14,34) that is fully rotatable and is movable axially for rotating the lamp (22) and focusing the lens assembly (25), respectively. The lens assembly is carried on a lens holder sleeve (26) and the lamp assembly is carried on a lamp carrier (21). The lamp carrier (21) is rotatable but is held against axial motion, while the lens holder sleeve (26) is held against rotation but is moveable axially. A sliding gear arrangement (36, 37, 38, 39) is formed wherein the lamp carrier sleeve (21) is configured with axially elongated teeth (38), thus serving as a sun gear. The outer control sleeve (14,34) has internal teeth (38) and serves as the ring gear. Planet gears (36) can be carried on the lens carrier sleeve (26).

Title: Mass spectrometry method using supplemental ac voltage signals.
Inventor: KELLEY PAUL E
IPC: H01J49/42
Filed: 1992-02-11
Abstract: A mass spectrometry method in which one or more high power supplemental AC voltage signals and one or more low power supplemental AC voltage signals are applied to an ion trap (16). The frequency of each supplemental AC voltage is selected to match a resonance frequency of an ion having a desired mass-to-charge ratio. The low power supplemental voltage signals are applied for the purpose of dissociating specific ions (i.e., parent ions) within the trap, and the high power supplemental voltage signals are applied to resonate products of the dissociation process (i.e., daughter ions) so that they can be detected. In one class of embodiments, the high power voltage signals resonate daughter ions out from the trap for detection by an external detector (24). In another class of embodiments, each high power voltage signal resonates the daughter ions only to a degree sufficient for detection by an in-trap detector (which may comprise one or more of the electrodes (11-13) which define the trapping field, or may be mounted integrally with such electrodes).

Abstract: The invention relates to an apparatus for strip casting comprising a tundish (3) and a pair of cooled casting wheels (1, 2) forming a casting gap. To provide a better seal between the end of the tundish (3) and the casting wheels (1, 2), the edge zones (1c, 2c) of the casting wheels (1, 2) are of tapered design and a two-layer wear-resistant and thermally insulating lining (3b, 3c) extends with its wear-resistant inner layer (3c) as far as the edge of the cylindrical circumference (1b, 2b) of each cooling wheel (1, 2), while the outer, thermally insulating layer (3b) extends as far as the tapered edge zones (2c), resting flat against them. The thermally insulating layer (3b) prevents an intensive flow of heat from the melt (S) into the casting wheels, and axial expansion due to the temperature of the casting wheels are accommodated by wear of the layer (3b). The wear-resistant inner layer (3c) ensures that the melt (S) is free from abrasion. <IMAGE>
