    A method is suggested for calculating the inception voltage and corona current in humid air. It is found that the photoelectrons distribution within the ionization layer, which depends upon the gap geometry, plays an important role in deciding whether the inception voltage increases or decreases with relative humidity. The inception voltage is one of the boundary conditions required in the theoret... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3821 KB)

    The saturation charge of conductive sharp-edged ellipsoidal particles imparted by field charging is measured and found to be in agreement with the theoretical value. The saturation charge decreases, however, when the charging electric field exceeds a certain value. When the decrease in the saturation charge takes place, a corona discharge is observed from the particle at its one edge facing downst... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3824 KB)

    A new solid-state scanning ink jet recording technique, called slit jet recording, is proposed. This technique uses a recording head with one slitlike ink-issuing opening having a number of recording electrodes arrayed along a horizontal scanning direction. The ink is emitted from the ink-issuing opening due to the electrical potential difference between a driven recording electrode and a countere... View full abstract»

    The dual to recent work of the labyrinthine instability in magnetic fluids is demonstrated with analysis and measurements using dielectric fluids. Here polarizable fluid layers are placed within an initially uniform electric field tangential to the fluid interface separating two dielectric fluid layers. To eliminate electric space charge effects, alternating electric fields must be applied at a fr... View full abstract»

    Loss-of-field relays operating on an impedance-measuring principle provide an important part of the protection of a synchronous generator by minimizing possible damage to the machine and low voltages detrimental to system operation. These relays require an external source of reactive power, such as a utility tie or other in-plant generators, to insure proper operation on loss of generator field. I... View full abstract»

    An approach is suggested for the cost-effective systematic design of product on-board diagnostics that allow simple and complex appliances to diagnose or predict failures within themselves. This methodology differs from other current less formal approaches in that it encourages a wholly integrated design philosophy. Trends indicate that on-board diagnostic capabilities will become much more import... View full abstract»
