Title: Scanning electron microscope
Inventor: GADAGI HUMIO
IPC: H01J37/153
Filed: 1980-07-09
Granted: 1985-02-18
Abstract: The scanning electron microscope has an XY type  electromagnetic stigmator for correcting the astigmatism of its focussing lens system. The astigmatism is corrected automatically by scanning the electron beam repeatedly on the specimen, and sequentially changing the excitation current in the X and Y direction coils of the stigmator. The signal from the specimen beam is converted into a signal indicating the diameter of the electron beam in the scanning direction. The excitation current in the coils is locked when the conversion signal reaches its maximum value.

Inventor: CREGG JAMES M
IPC: C12N1/16
Filed: 1986-10-20
Granted: 1993-04-09
Abstract: Method for the site specific genomic modification of yeasts of the genus Pichia and novel DNA sequences useful therefor are provided. Pichia is transformed with a serially arranged linear DNA fragment comprising first and second insertable DNA fragments, which flank a marker gene. The insertable DNA sequences are homologous to defined portions of the Pichia genome and integrate by recombination at such defined sites. The resulting transformed organism contains the marker gene and any additional DNA sequences which are positioned between the insertable DNA fragments. In addition, the resulting transformed organism has either a disrupted or deleted sequence at the site of the genomic modification. Enhanced production of heterologous gene products is observed when using as the host for expression strains in which the alcohol oxidase gene has been disrupted. Upon disruption of the primary alcohol oxidase gene of Pichia, the existence of a second alcohol oxidase gene in Pichia was also discovered.
