Abstract: A laser alignment control system comprises a method and apparatus wherein a rotating member such as a spindle can be properly aligned with a workpiece for manufacturing operations thereon. The system comprises a laser whose beam impinges on a target with the laser and target being interchangeably mounted on a spindle and a "master part". Information from the target is fed through interface circuitry to a computer which calculates an "effective target" relative to the shim feet under the movable master part or spindle. This "effective target" gives the system capability for aligning the operating member both as to coincidence of location and appropriate incident angle with points within the workpiece which are physically inaccessible. The computer outputs information onto a multiplicity of display screens wherein an operator can align the spindle with the "master part" axis by a series of shimming movements. The major steps of spindle alignment comprise making the ways of the wingbase supports for the spindle straight, adjusting the wingbase ways such that they are parallel to the "master part" axis, making the spindle axis parallel to the "master part" axis, and centering the spindle to the "master part" axis.

Patent CA-2032413-A1 (CA)
Inventor: ENGELKE HELMUT
IPC: G03F1/20
Filed: 1990-12-17
Abstract: For  the  fabrication  of  semiconductor  chips  with  an increasing number of electrical elements it is necessary that the geometry of the elements becomes  smaller and smaller.  For that purpose,  lithographic techniques have been  developed  using  x-rays,  electron  or  ion  beams. Especially for particle beams,  self-supporting masks are stringent with the consequence that it is not possible to fabricate, for example, a ring-shaped structure with one mask. This mask stencil problem is solved by exposing the chip with two complementary masks. The present application relates to a method for automatically splitting one layout into two complementary patterns for the two masks.  The method determines all corners of the layout which extend into a hole representing area of the masks. A stability criterion  is  carried  out  for  the  corners,  with  the consequence  that  only  unstable  corners  are  used  for cutting  the  hole  representing  area  into  sections. Subsequently the sections are distributed onto the two patterns alternatively.

Title: Maximum likelihood sequence estimation apparatus
Inventor: KUBO HIROSHI
IPC: H04L25/30
Filed: 1990-12-20
Abstract: A maximum likelihood sequence estimation apparatus for estimating a transmitted signal sequence from a received signal sequence and an estimated channel impulse response characteristic.  A merge detection circuit computes a time required for respective merges, that is, the time required for convergence of all possible path to one state, instructs the maximum likelihood sequence estimation circuit to output a decided maximum likelihood data sequence to a channel impulse response characteristic estimation circuit based on such merge time and instructs a received signal hold circuit to output a held received signal to the channel impulse response characteristic estimation circuit.  Thereafter, the channel impulse response characteristic estimation circuit immediately estimates the channel impulse response characteristic using the data from the maximum likelihood sequence estimation circuit and the received signal hold circuit.  The apparatus allows the channel impulse response characteristic to be estimated at a higher speed, thus improving system efficiency.

Abstract: Methods and materials fox the cloning of DNA, in particular, for the cloning of "unclonable" DNA using genetically engineered host cells. Host cell organisms have been discovered that stabilize and inhibit rearrangement of DNA molecules capable of forming non-standard secondary and tertiary structures.   Organisms are engineered to contain at least one mutation which inactivates homologous recombination and at least one mutation in a DNA repair pathway. Examples of such DNA pathways include Uv repair pathway, the SOS repair pathway, the mismatch repair pathway, the adaptive response pathway, the heat shock response pathway, the osmotic shock response pathway, the repair pathway of alkylation damage, the repair pathway of uracil incorporation into DNA and pathways involved in maintaining DNA superhelicity.      The host organisms of this invention are suitable for cloning DNA capable of forming non-standard and tertiary structures such as found in eukaryotic DNA.
