Title: Dynamic compensation of induction effects in electron optical devices especially for electron beam lithography using raster microscopes
Inventor: SVINTSOV ALEKSANDRE
IPC: H01J37/304
Filed: 1998-08-22
Abstract: The method includes measuring the dynamic behavior of a device and controlling the movement using the measured parameter, with addressed beam movement along a calculated virtual track. The method of dynamic compensation involves first measuring the individual dynamic behavior of a device. The movement is then controlled using the measured parameter such that the desired movement is precisely achieved. The control is a speed dependent digitally address control. The beam should, after it has suddenly moved from another position, run with constant speed on the horizontal line (1). If the beam movement along the line is addressed, then a curved course results which never meets the line. It is thus necessary to address the beam along a calculated virtual track (5) so that it effectively runs along the line.

Patent DE-19844860-A1 (DE)
Inventor: CHAPMAN JOHN
IPC: F15B13/042
Filed: 1998-09-30
Abstract: The invention relates to a manually operated control device, especially for hydraulically actuating hydraulic valves. Such a known control device is provided with a control lever (21) which can be universally swiveled around the swivel axis (23) from a neutral position around axes which lie in a plane of axes and intersect in a swivel axis. The device has at least two control signal transmitters (11) which are arranged 90 DEG  away from each other in relation to a lever axis which is perpendicular to the axial plane and intersects the swivel axis. The two control signal transmitters can be operated either singly or jointly by an actuator (30) to generate a control signal, which actuator is substantially parallel to the axial plane and is fastened to the control lever (21). For the control device to be able to actuate a plurality of hydraulic valves with as little complication as possible the invention provides the following solution: An additional control signal transmitter is arranged between the two first control signal transmitters. The control lever (21) can be swiveled together with the actuator around the lever axis from a first swivel position, in which the first control signal transmitters can be operated by the actuator, to a second position and vice versa. The actuator is provided with a recess (32) which permits actuation of the additional control signal transmitter only in the second swivel position.

Abstract: The invention relates to a method for producing hexane diol-1,6 from a mixture of an adipic acid, 6-hydroxycapric acid and a carboxylic acid which contains small quantities of 1,4-cyclohexanediols which is obtained as a by-product during the oxidation of cyclohexane to cyclohexanon/cyclohexanol after the extraction of water from the reaction mixture by subsequent extraction, using aqueous caustic soda lye. The hexane diol-1,6 is produced by means of the esterification of the acids and hydrogenation. According to said method a) the carboxylic acids are liberated from the alkaline extract by the addition of a mineral acid, b) the organic phase which contains carboxylic acids is separated into a distillate which contains the low-molecular monocarboxylic acids and a residue which contains the adipic acid and 6-hydroxycapric acid, c) the mono and dicarboxylic acids, contained in the aqueous dicarboxylic acid mixture are reacted with a low-molecular alcohol into the corresponding carboxylic acid esters, d) superfluous alcohol and agents with a low-boiling point are liberated from the resultant esterification mixture in a first distillation stage, e) the residual product is separated in a second distillation stage into an ester fraction which is substantially devoid of 1,4-cyclohexanediols and a fraction which contains at least the greater part of the 1,4-cyclohexanediols, f) the ester fraction which is substantially devoid of 1,4-cyclohexandiols is catalytically hydrogenated and g) hexanediol-1,6 is obtained from the hydrogenation product in a pure distillation stage in the known manner.
