IPC: H01H13/50
Filed: 1989-01-07
Abstract: A slide (2) in the housing (1) can move along a switching path (S) from a quiescent position into a switched position and back. The locking function is achieved by means of the interaction of a pin (6), supported on a moving bearing (8), with a guide curve (5, 13) which on the one hand has a locking step (b) and on the other hand, in the movement direction of the slide (2), has a linear extension (13) in which the pin (6) rests in the quiescent position of the slide (2). In order to simplify a space-saving design and functional movement it is provided that the bearing (8) can move parallel to the slide (2) between a first and a second position. It is further provided that, in the quiescent position of the slide (2), when the bearing (8) is located in the first position (Fig. 2a), the switching path (S) is shorter than the distance (A) of the pin (6) from the locking step (b) and is greater than said distance (A) when the bearing (8) is located in the second position (Fig. 2b).

Abstract: In order to generate a frequency-time profile of the control pulses of stepper motors, frequency values that determine the frequency of the control pulses are incremented during a starting phase. During a phase (S2) of constant speed, the last frequency value of the starting phase is maintained, and during a stopping phase the frequency value is decremented. The steepness of the rise in frequency in the starting phase, and drop in the stopping phase is determined by the frequency of the incrementing or decrementing pulses. The duration of the starting phase is yielded by the steepness of the rise in frequency and of the final frequency. The traversed distance covered in the starting phase is measured by summing up the control pulses. The stopping phase is introduced when the state of a residual path counter, which is decremented with the control pulses, is equal to the number of the pulses summed up in the starting phase. The invention is applied to actuators with stepper motors. <IMAGE>

Abstract: A capacitance based, high resolution, incrementally encoding, position measuring system employs an array of identical replicated electrodes that are driven in unison from an RF source and mounted in proximity to a patterned monolithic reference ground plan of arbitrary size. Motion of such position-­sensing arrays is monitored by measuring both the sums and the differences of the electrode displacement currents in such a way as to provide incrementally encoding position signals  in both one and two dimensions  together with a continuous measurement of the height of the sensor array above the patterned ground plane. In various modifications, the system and methods are applied both to one dimensional linear, as well as to two dimensional planar and two dimensional cylindrical motion measurement and control. Various techniques for eliminating the effects of spurious capacitances are also disclosed.

Abstract: A method of supporting or mounting a precision instrument for supporting a mask and a wafer in a vacuum container. It is particularly applicable to a SOR-X ray exposure apparatus wherein the mask and the wafer are disposed in a desired level of the reduced pressure, and exposure energy such as X-rays contained in synchrotron radiation is projected onto the wafer through the mask to print the pattern of the mask onto the wafer. In x-y-z coordinates with the x direction being vertical, the precision instrument in hung at at least two points which are spaced in the x direction, to the inside wall of the vacuum container. At one of the supporting points, the precision instrument is given latitude of x, y and z direction movement, and at the other supporting point, the precision instrument is fixed or is given a latitude only in the x direction. By this, when the vacuum container deforms by the difference between the internal and external pressures, the precision instrument can be supported correctly.

Abstract: A motor control device carries out feedback control of a motor such that the rotational speed of the motor is equal to the command speed. A control voltage is first calculated as the sum of a first constant times the difference between the command speed and the actual rotational speed, a second constant times the actual rotational speed and a predetermined offset value. The calculated control voltage is corrected on the basis of the phase difference between the command speed and the actual rotational speed and a voltage after the correction is outputted as a motor control voltage. The rotational speed of the motor can be caused to rapidly follow the target speed by adjusting the first and second constants and the offset value whether the command speed is relatively low or high, thereby to make it possible to control the motor at a constant speed.

Abstract: A circuit protector employs molded resinous parts including a base and a support frame structure. Advantageously the circuit protector support frame structure may include a medial plane frame providing space for two circuit protectors, one on each side of the frame and a common back plane mutually perpendicular to the medial frame and the base along one edge of the base. A cover fits over the support frame and base and snugly accommodates the base at its terminal edges except immediately along the back plane. The back plane is provided with a slot through the back plane in the vicinity of each pair of contacts which communicates to a space between the cover and the back plane of the base permitting venting of gases generated by arcing. Grooves are supplied in the medial plane frame and the back plane to accommodate edge flanges of an arc suppressing grid to hold the grid in place to bracket the contacts. The movable contact in each case is supported on a resilient contact support which is limited in its maximum open position by a stop supported on the back plane or medial plane frame. 
     The base outside of the housing is provided with pockets which surround on three sides of each of the terminals and insulate them from one another. In a preferred two circuit protector configuration, one side of each pocket is formed by the base, one by a wall between the terminals for the respective circuit protectors and one by a wall between terminals for the same circuit protector. A spade terminal is provided which may be adapted to a screw terminal by an L-shaped adapter, one leg of which provides a bracket snugly engaging the spade terminal. A spring detent engages an opening in the spade terminal to latch the adaptor in place. The other leg of the L provides a support bracket arranged to be engaged by a retaining groove in an insulating wall and provides threaded means to be engaged by another threaded means. One of those threaded means is a screw or threaded stud which passes through a hole in a saddle member arranged generally parallel to the support bracket leg of the L-shaped member and has flanges which embrace that support bracket along the opposite edges.
