Title: Single clocked latch circuit
Inventor: MALEY GERALD ADRIAN
IPC: H03K5/135
Filed: 1984-11-14
Granted: 1987-09-10
Abstract: An edge triggered polarity hold, clocked latch circuit is disclosed which requires the use of only a single clock line for operation. The latch circuit comprises three set-reset type latches (1, 2, 3). Each of two latches (1, 2) receives one set and one reset signal. The third latch (3) receives two reset signals and one set signal. A single clock signal is applied jointly to a reset terminal of the third latch (3) and of one of the first two latches (1, 2). A data signal is applied to the set terminal of the third latch (3). The other of the first two latches (1,2) constitutes the output latch (2) and is connected to receive the outputs of the remaining latches. The output latch (2) produces an output equal to an input data signal upon each occurrence of the leading edge of an input clock signal. The output is held (latched) until the occurrence of the next clock signal when the output becomes equal to the then existing input data signal.

Title: Proximity effect correction method for e-beam lithography
Inventor: FORSTER THEODOR
IPC: H01J37/317
Filed: 1984-05-30
Granted: 1989-01-05
Abstract: Data from a computer are supplied to a pattern generator and represent the shape to be produced. The origin coordinates and incremental steps are signalled to a digital-analog converter. The resulting signals are supplied to the electron beam deflection coils (19,21) following amplification (29). A detector determines a signal representing the rate of electron back-scattering. The signal is amplified and applied to a multi-level range coder. The corresponding level signal is applied to a stepping rate selector which produces a corresponding stepping rate correction which corresponds to the signal level. This is converted to an ac voltage for application to a VCO controlling the beam stepping rate signal for the pattern generator.

Title: Semi-submersible vessel
Inventor: BENNET WILLIAM
IPC: B63B/
Filed: 1984-12-31
Granted: 1989-11-09
Abstract: An improved semi-submersible unit for use in offshore operations which has a significantly reduced susceptability to heave motions in wave periods which are most likely to be encountered during practical operation conditions. The unit consists of a lower hull or hulls supporting vertical buoyant caisson which also support an upper deck or platform which supports and is supported by a centrally disposed, large diameter buoyant caission which contributes a significant portion of the total water plane area of the vessel when it is submerged to its operational draft. The vessel may be configured for offshore drilling operations, diving support, and various other offshore support functions. When configured for the offshore drilling operation, the central column serves as buoyant chamber and as a primary storage chamber for tubular products which are associated with the drilling function. This clears the deck of the vessel for other operations and introduces a less hazardous method for handling tubulars than in previous designs. The central caisson has an interior annulus which is open both to the drill floor and the sea through which operations may be carried out. The improved semi-submersible vessel exhibits significantly less heave in operational wave conditions than existing semi-submersibles or similar water plane area and displacement.

Abstract: The present invention provides a laser scanning system of compact size and relatively long focal length which my be used in a laser surface inspection system for silicon wafers and the like. The scanning system employs a folded optical cell (30) having a pair of reflective surfaces (31, 32) so oriented that the scanning laser beam is folded, and reflects from each of the reflective surfaces several times to significantly increase the focal length. The folded optical cell is also effective to produce a collimated, substantially parallel scan pattern such that the beam remains perpendicular to the inspection surface as it is scanned. The folded optical cell can also be set for divergent or convergent scan.

Abstract: An AC gas discharge display panel is described which employs the phenomenon of plasma spreading. In the panel, plasma spreading or "coupling" is employed to couple the plasma at an addressed cell to one of a plurality of pixels to be illuminated. The spreading is controlled by assuring that the cell wall voltages are properly related so that the plasma's electrons migrate to a region where the voltages are approximately equal to or more positive than the wall voltages where the plasma originated. Paired sustain electrodes are selectively energized to enable diversion of the coupled plasma to the desired pixel, so that upon subsequent applications of a sustain voltage, the desired pixel is illuminated (or erased) as the case may be.
