Abstract: A three-dimensional mouse system for a computer's display, or a robot, comprising a pointer, movable in space by the user; a transmitter, being an integral part of said pointer; at least three receivers; a processing unit, having a microprocessor, an input/output communication interface and a connecting unit for information and power transfer; and a soft-ware means. 
     The transmitter and the receivers are connected to the microprocessor through the input/output communication interface. The microprocessor is connected through the input/output communication interface to the connecting unit, attached to the computer. 
     When the receivers react to a signal received from the transmitter, they transfer independently to the microprocessor their output signals, depending correspondingly on the space position of the transmitter with reference to the receivers; and the microprocessor computes the space position of the transmitter; and the output signal of the microprocessor is transformed into an appropriate form and is then transferred to the computer and processed by the software means to provide on the computer's display or in the robot's action a three-dimensional reflection, corresponding to the movement of the pointer, in real time, in space.

IPC: G03F7/40

Abstract: The sensitivity and dry etching pattern control of chemically amplified resists used in the production of devices such as electronic devices is substantially enhanced while image quality is improved through use of a specific expedient. In particular, the resist material after coating on the device substrate, is treated e.g., heated to sufficiently high temperatures, to remove a portion of the protective groups on the polymeric component of the resist. Generally, when removal up to approximately 90% of the protective groups for substituents such as t-butoxycarboxyl is effected through this procedure, sensitivities as good as 10mJ/cm² for an X-ray exposure (λ = 14Å) have been achieved, and both the image quality and dry etching pattern control are improved.

Abstract: A machine is disclosed having novel air bearings for supporting one machine part for translational movement on another part in a first direction X. Each bearing takes the form of a track (5A,14,16) on one of the parts providing concave part-cylindrical bearing surfaces (5A,14A,16A) and pads 25 on the other part providing confronting convex part-cylindrical bearing surfaces 25A. The arc lengths of the part-cylindrical bearing surfaces are such as to provide restraint against relative movements between the machine parts in at least one sense of both of the two directions (Y,Z) orthogonal to the direction (X) of the translational movement. The advantages are relative cheapness of manufacture compared to vee- bearings and a capability of the bearings to self-align under load.

Abstract: A method and apparatus (10) for fastening upper and lower workpieces (20, 22) without movement of the workpieces. The apparatus is provided with a frame having upper and lower portions (24.1, 24.2) carrying upper and lower riveting ram assemblies (26, 28), respectively. Each riveting ram assembly includes a buck ram (30 or 32), a buck ram moving assembly (62 or 90, 92), a pressure foot (34 or 36), a pressure foot moving assembly (38 or 40), a buck ram position measuring device (74 or 104), and a pressure foot position measuring device (78 or 108). The upper pressure foot moving assembly (38) further includes an upper pressure foot compensation cylinder assembly (42). The apparatus also includes a load cell (112) carried by one of the buck rams for sending a force signal in response to the force being applied to the fastener during upset and thereafter. A programmable process controller (82) is provided which is capable of having programmed into it the length of a fastener, and a deflection compensation table which sets forth the deflection of a portion of the frame during upset. The controller modulates sequential operation of the various moving assemblies during operation to move the buck rams and the pressure feet in response to signals received from the position measuring devices and the load cell in such a manner that the fastener may be upset while maintaining the upper surface (122) of the upper workpiece (20) in a desired workplane (124) even though one portion of the frame may deflect more than another portion of the frame.

Abstract: Cette invention concerne un cycle de réfrigération régénérative à absorption amélioré présentant un rendement élevé, et comprenant un système de pompage utilisable au niveau commercial. Dans ce cycle frigorifique, la vapeur d'ammoniac évaporée provenant du générateur est refroidie (14) dans un régénérateur (16), puis condensée (28) et détendue jusqu'à basse pression (32) pour être ensuite mise en ébullition dans un évaporateur (34) afin de récupérer la chaleur du fluide qui circule vers une charge de refroidissement (41) et inversement. L'ammoniac liquide à basse pression retourne ensuite (46) vers le régénérateur (16) pour êtetre absorbé en retour dans l'eau à basse pression provenant du générateur. La solution est ensuite refroidie dans de l'eau à basse pression provenant du générateur. La solution est ensuite refroidie dans un absorbeur (50) à basse pression, puis pompée (53) vers une conduite à haute pression (57) qui est chauffée par la chaleur du régénérateur avant de retourner vers le générateur (11). Le cycle amélioré utilise au moins un étage intermédiaire d'absorbeur (60) qui lui permet d'absorber une plus grande quantité de vapeur d'ammoniac (69, 71) dans la solution provenant de l'absorbeur (50) à basse pression afin de produire une solution refroidie dont la teneur en ammoniac est plus élevée. On peut utiliser cette plus forte teneur en ammoniac pour pré-refroidir (87) le réfrigérant liquide avant la détente (32).

Abstract: A hand washing and rinsing unit which operates automatically without the need for the user to touch any part of the unit. When the user's hands are inserted into a wash basin (12), a proximity switch (30) actuates the system to switch on a supply of water through a supply line (18). After a predetermined time interval such as 5 to 8 seconds, a metered quantity of liquid soap from a supply (28) is dispensed onto the user's hands, and the supply of water continues to enable the soap to be washed off. The system incorporates an electronic monitoring system to record each use, this being triggered only when soap has been dispensed, so that it is not possible to have a wash recorded merely by wetting the hands for a few seconds.

Abstract: Disclosed is a method and apparatus for laying out a plurality of instances (180) of graphical objects within a view (100) displayed on a graphical display device (80). The view (100) contains one or more regions (110) into which the instances (180) may be placed. The placement is done by associating an attribute, parameter or variable (RegionProp) with the definition of each of the instances (180) of graphic objects. The attribute (RegionProp) defines into which of the regions (110) of the view (100) the instance (180) should be placed. Layout routines (200) are provided to extract the value of the attribute (RegionProp) from the definition of the instance (180) of the graphic object and to use it to associate the instance (180) with the region (110) in which it is to be displayed. The layout routines (200) then calculate an optimum display for all of the instances (180) within the region (110). 
     Disclosed also is a method for moving the instances (180) of the graphic objects from one region (110) to another region (110). This involves changing the value of the attribute (RegionProp) and reordering the instances (180) within the regions (110).
