摘要:
An integrated circuit is wire bonded in a manner such that there is consistent RF performance from integrated circuit package to integrated circuit package. Bond distances within the integrated circuit are measured, each corresponding to a wire bond to be formed. An area under a hypothetical wire bond profile is calculated as a function of the bond distances, a baseline wire length, and a baseline loop height. A wire is bonded across a given one of the bond distances to form a given one of the wire bonds. A wire bond profile for the given wire bond is provided having an area thereunder that is substantially equal to the calculated area.

The present invention relates to sigma-2 receptor agonists and their use in the treatment of immunodeficiency virus infections, especially human immunodeficiency virus (HIV) infections. The invention particularly relates to sigma-2 agonists, especially CB-184 and its analogues, that decrease cellular production of sphingomyelin when provided to recipient cells, and inhibit HIV replication.

A method facilitates assembling a variable vane assembly for a gas turbine engine including a casing and an inner shroud. The method comprises providing at least one variable vane including a radially inner spindle that includes a groove defined therein that has at least one machined face, and coupling the variable vane radially between the casing and the inner shroud such that at least a portion of the radially inner spindle is inserted at least partially through an opening extending radially through the inner shroud. The method also comprises securing the variable vane to the inner shroud by engaging the spindle machined face with a retainer coupled to the inner shroud.

The present invention relates to a class of compounds having affinity for certain cancer cells, e.g. lung carcinomas, colon carcinomas, renal carcinomas, prostate carcinomas, breast carcinomas, malignant melanomas, gliomas, neuroblastomas and pheochromocytomas. The compounds of the present invention can also bind with high specificity to cell surface sigma receptors and can therefore be used for diagnostic imaging of any tissue having an abundance of cells with sigma receptors. The present invention provides such compounds as agents for diagnostic imaging and for detecting and treating tumors containing the cancer cells described above.

A transmission line balun transformer for providing a single ended output signal from a pair of differential input signals includes two transmission line signal couplers. The couplers are individually designed to be relatively loosely coupled devices, i.e. having a coupling factor greater than 3 dB, but are coupled together with proper phase relationships so as to achieve a relatively tighter composite coupling characteristic in the order of 3 dB, thereby resulting in an increase in bandwidth.

Certain nitrogen-containing cyclohetero cycloalkylaminoaryl compounds are described for treatment of CNS disorders such as cerebral ischemia, psychoses and convulsions. Compounds of particular interest are of the formula: ##STR1## wherein each of R.sup.1, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 is independently selected from hydrido, lower alkyl, benzyl, and haloloweralkyl;wherein each of R.sup.2, R.sup.3 and R.sup.8 through R.sup.11 is independently selected from hydrido, hydroxy, loweralkyl, benzyl, phenoxy, benzyloxy and haloloweralkyl; wherein n is an integer of from four to six; wherein m is an integer of from two to four; wherein A is selected from phenyl, naphthyl, benzothienyl, benzofuranyl and thienyl; wherein any of the foregoing A groups can be further substituted with one or more substituents independently selected from hydrido, hydroxy, loweralkyl, loweralkoxy, halo, haloloweralkyl, amino, monoloweralkylamino and diloweralkylamino; or a pharmaceutically acceptable salt thereof.
