ABSTRACT
Selective writing of information on a chosen channel of a large memory system (e.g., a magnetic drum memory) and selective reading of information from one out of many such memory channels can be accomplished by use of a single 2-way magnetic pyramid made solely of high quality magnetic saturable cores. A description is given of a working magnetic selection unit used in a large inventory control system with a few thousand magnetic drum channels.

Magnetic flux concentration at micrometer scale
This paper presents the study of magnetic flux concentration phenomenon of magnetic flux concentrators (MFCs) at the micrometer scale. The main physical principles of magnetic flux concentration were studied by using analytical calculations and finite ...
Magnetic fluid deformation mirror for large scale aberration correction
EITCE '22: Proceedings of the 2022 6th International Conference on Electronic Information Technology and Computer EngineeringWith the increasing use of adaptive optics and large telescope projects, new requirements have been placed on wavefront correctors. The magnetic fluid deformable mirror is a new type of wavefront corrector that changes the ferrofluid surface by changing ...
Multi-pole fine magnetic scale for high-resolution magnetic encoders evidenced by a simplified method
Magnetic encoders are widely used in linear and rotary positioning applications, specifically under harsh environments. The finer the magnetic pole-pitches of the magnetic scale in magnetic encoders the higher the resolution of the encoder. Conventional ...
