Filed: 1995-08-31
Abstract: In a refrigeration motor/compressor unit the compressor end-plate 2 is made thin so as to respond to pressure differences across it, movements of the end-plate varying the compressor rotor clearance as needed. The moving parts including shaft 10 carrying compressor rotor 3 and motor rotor 14 are lubricated by oil circulating with the refrigerant so that no dedicated oil pump or oil misting device is necessary. The compressor housing 4 and electric motor stator 9 are a close fit within a tubular casing 1. To provide adequate bearing support for the driving shaft 10 bearing 28 and the corresponding part of the compressor housing are of substantial length. The casing 1 includes an off-axis outlet 13 allowing oil to pass from the casing with the refrigerant gas in any orientation of the assembly from substantially horizontal to vertical. The motor/compressor unit may be incorporated in a refrigeration or air-conditioning system including a desuperheater heat exchanger 27. <IMAGE>

Title: Preparation of L-tryptophan from mutant strains of Escherichia coli
Inventor: CAMAKARIS HELEN
IPC: C12N1/20
Filed: 1995-09-05
Abstract: An E.coli strain which 'over-produces' L-tryptophan, comprises, in the genome thereof, a mutant gene which encodes partially-defective tryptophanyl-tRNA synthetase (preferably the trpS378 allele) - which when present in a non-producing strain, is characterized by a temperature-dependent tryptophan auxotrophy - and has a further mutation on the chromosome thereof in at least one gene selected from mtr (especially mtr - 24 ), aroP (especially aroP579 ), tnaA (especially tnaA1 ) and tnaB . The strains may be transformed with a plasmid which carries the tryptophan operon encoding an anthranilate synthase enzyme, freed from feedback inhibition by tryptophan, and/or which possess mutations in at least one gene selected from the trpEDCBA - group (which, when present in a non-producing cell, confers tryptophan auxotrophy thereon). L-tryptophan may be prepared by the cultivation of the said strains at ca. 30 degrees C (preferably in the presence of yeast extract), limiting growth by the concentration of available phosphate (in an appropriate medium), followed by fermentation (in the absence of yeast extract) at from 33 to 37 degrees C. The fermentation is preferably effected in the absence of antibiotics.

Title: Laser based method and system for integrated circuit repair or reconfiguration
Inventor: SWENSON EDWARD J
IPC: H01L23/52
Filed: 1997-10-29
Abstract: The present invention provides a method and system for irradiating resist material from multiple target positions (150) on one or more IC chips (12) with individually directed laser output pulses (74, 94). In one embodiment, an IC (12), including one or more etch targets (104, 106) such as conductive links (72, 92), is coated with an etch protection layer (90) of photoresist material. Then, position data direct, toward multiple positions (150) on the photoresist material, individual laser output pulses (94) of predetermined parameters selected to expose the photoresist material. Because photoresist exposure requires less energy than link blowing, low-power UV lasers (120) can be employed, and their shorter wavelengths permit a smaller practical laser output spot size (98). Because the nonablative process does not generate debris, an optical component (148) can be brought within 10 mm of etch protection layer (90) to focus the laser output pulses (94) to a spot size of less than two times the wavelength of laser output (140). Thus, an advantage of this embodiment permits microcircuit manufacturers to decrease the pitch distance (28) between circuit elements (14). After the photoresit layer (90) is developed, the accessible etch target (92) can be etched to repair or reconfigure the IC device. In another embodiment, slightly higher UV power laser output pulses (74) can be employed to ablate an etch protection resist layer (70) so any type of etch protection coating such as nonphotosensitive resist materials can be utilized with substantial manufacturing and cost benefits. Etching of the accessible etch targets (60, 62) follows this process.
