Abstract: ABSTRACT OF THE DISCLOSURE     METHOD OF TRANSFORMING HIGH LEVEL LANGUAGE STATEMENTS INTO MULTIPLE LOWER LEVEL LANGUAGE INSTRUCTION SETS          Disclosed is a method of transforming an assignment statement of a high level programming language, such as ALGOL and COBOL, into first, second, and third sets of lower level object language instructions wherein instructions of the first set are executable in an interleaved fashion with instructions of the second and third sets, the latter two of which are executable at the same time.  When the instructions of the first, second, and third sets are executed in the above-recited fashion, a substantial improvement in the execution time of the corresponding assignment statement is attained.

IPC: H01L21/30
Filed: 1984-05-16
Granted: 1987-07-28
Abstract: CORRECTION OF LITHOGRAPHIC MASKS A lithographic mask is corrected by ion beam removal of material at the location of a defect after the mask is initially formed. In the case of defects due to excess material (opaque defects), the ion beam removes the excess opaque material. In the case of pinholes (clear defects), the substrate (typically glass) is rendered opaque. The ion beam may be used for imaging the defect, typically by detection of secondary electrons or photons emitted where the ion beam impinges on the mask. Optical masks (visible, ultraviolet) and X-ray masks, among others, can be corrected.

The patterned member is moved by a pair of rollers arranged to define a nip, one of the rollers being driven by the electric motor.          Power is applied to the electric motor to start rotation of the rollers and movement of the electrophotographic member simultaneously, the rollers arranged to enable a patterned member to be pressed into said nip while the motor is not energized and neither the electrophotographic member nor the one of the said rollers is rotating, at which time the electric motor can be energized manually causing synchronized movement of the patterned member and the electrophotographic member.

Abstract: SWITCH FOR FINE ADJUSTMENT OF PERSISTENT CURRENT LOOPS               IN SUPERCONDUCTIVE CIRCUITS                     Abstract of the Disclosure A small portion of a lead for a superconducting coil is made to function as a controllable resistor with a low resistance value and fast thermal response so as to be capable of rapidly being switched between the superconduct-ing and resistive states.  The device is thus capable of fine adjustment of the current flowing in a superconducting loop.  The switch includes lengths of parallel conductor so that the resulting section of superconductive material is cryostable.  The superconducting coil lead is disposed on a substrate so as to permit ready access for helium or other cryogenic coolant to most lead surfaces.  The small mass and close contact with the coolant produce rapid turn-on and turn-off response characteristics.  Furthermore, the low overall resistance causes the coil current to decay slowly, thus preventing precise control of the superconducting current.
