IPC: B30B11/00
Filed: 1989-06-15
Abstract: The invention relates to a method and an apparatus for making dimensionally stable pressed articles from pulverulent compositions, in particular from metal powder, on a press in a mould under the action of at least one lower die and one upper die, the position of the components carrying the dies and/or of the mould being measured relative to a fixed point and the components carrying the dies being moved, in each case, into a theoretical position relative to each other, these positions corresponding to the theoretical dimensions of the pressed article in the pressing direction, taking into account the lengths of the dies. In order to provide a method, and an apparatus for carrying out the method, by means of which the accuracy of the geometry of the pressed articles can be further improved, even in the case of pressed articles with a plurality of vertical steps, it is proposed that, in the final pressing position, the theoretical position of at least one of the components carrying the dies is corrected, in the pressing direction, by an amount which corresponds to the elastic deformation of the die or dies as a consequence of the action of the compressive force.

IPC: B30B11/00
Filed: 1989-06-15
Abstract: The invention relates to a method and an apparatus for making dimensionally stable pressed articles from pulverulent compositions, in particular metal powder, on a press in a compression mould with at least one upper die and at least one lower die, in which the pressing dies in the final pressing position are moved to predetermined theoretical positions, and, during the pressing, the progression of the compressive force of at least one of the dies is recorded as a function of the travel and compared in each case with a predetermined, travel-dependent tolerance range for the compressive force. In order to provide a method and an apparatus which permit even closer tolerances as regards the dimensional accuracy of the pressed articles and at the same time further reduce the risk of defective production, it is proposed that, if the tolerance range is exceeded, the theoretical position of the die in question in the final pressing position is modified so that the height of the pressed article in the final pressing position is reduced by an amount which corresponds to the increased upward expansion of the pressed article after its unmoulding, associated with the higher final pressing force, and the reverse procedure is adopted if the compressive force falls below the tolerance range.

Title: Workpiece table for handling semiconductor wafers
Inventor: WAGNER RUDOLF
IPC: C23C16/48
Filed: 1989-05-08
Abstract: A table lift, for transporting thin disc-like workpieces such as silicon wafers from a lower feed-in position to a higher process chamber position, consists of a central column (3) which carries the worktable (5) at its top end. Further below, a large ring flangee (7) bears against the device housing. The same carries servo motors (12) which transmit their torque to axles (10) when the arms (14) with its fingers are to grip the work piece (6) or respectively to release it. After the workpiece is lifted into the vacuum chamber and sealed, the arms (14) are turned outwards by the servo motors (12), and thereby come to be placed below a protective ledge (34) so that the effect of the acid and other substance deposition applied to the workpiece will not be applied to the holding arms.  While the transporting and holding gear is withdrawn, a loose ring surrounds the work piece thus keeping it in place.

Abstract: A regulating system for a pulse-invertor-controlled rotating field machine consists of a multiphase, preferably three-phase rotating field machine, for example a synchronous machine, preferably an asynchronous machine, of a pulse invertor, which supplies the rotating field machine with a multiphase AC voltage, preferably a three-phase voltage, and is supplied with DC voltage, of a pulse generator (3) for controlling the switching state of the pulse invertor, and of a machine controller for predetermining a desired voltage vector (Usoll  alpha , Usoll beta ) for the pulse generator (3), the output voltages (U1, V1, W1) of the pulse invertor being measured and supplied to the pulse generator (3) as the actual voltage corresponding to the actual, instantaneous switching state of the pulse invertor. In order that a non-ideal behaviour of the pulse invertor and of the DC voltage predetermined for the pulse invertor can be completely regulated out, the vectorial difference (18, 19) between the desired voltage vector (Usoll  alpha , Usoll beta ) and the actual voltage vector (Uist alpha , Uist beta ) is formed in the pulse generator (3). This difference is subsequently vectorially integrated (20, 21). The result of this integration, that is to say the integrated difference vector, is used as the main criterion for determining the optimum switching states of the pulse invertor (Fig. 3). <IMAGE>

Title: Assembling O=rings in bores - involves O=ring supported on radially spring-loaded pins forcing it into shape that can enter bore
Inventor: WOESSNER JOHANNES DIPL ING
IPC: B25B27/00
Filed: 1990-11-19
Abstract: The equipment has eight pins which support the O-ring and allow it to be inserted by robot for example into the bore in alignment with the groove seating. The rear ends of the pins are carried in equi-spaced radial slides which are spring loaded outwards and can be traversed by pneumatic cylinders. Four of the pins (1) are 'spreader pins' acting on the inside of the O-ring and four (2) are 'pressure pins' acting on the outside. The O-ring is picked up (6b) by moving the pressure pins inwards and allowing the spreader pins to take up an equilibrium position under spring pressure. The O-ring which is larger in diameter than the bore, can now be inserted and aligned with the groove. The pressure pins are next moved outwards against the bore surface, thus causing the spreader pins to move outwards and force the O-ring into the groove at four points. The pressure pins can now be withdrawn axially and the workpiece rotated to seat the O-ring completely. USE/ADVANTAGE - Equipment is easily adjustable for a variety of ring sizes and can therefore be applied to batch manufacture.
