Abstract: A current regulator controls the electron emission from a cold cathode using closed-loop feedback from a current sensor in the cathode connection. The regulator circuit includes a cold cathode, a current-sensing element, a current-limiting element, and current-control element. Additionally, the closed-loop current regulator may comprise a reference element for generating the reference level, a circuit power supply and a cathode bias supply. The regulator and cathode may be assembled from separate components, or the entire circuit may be integrated onto a single substrate. In one embodiment, the current level is set by adjusting the reference element directly. In a second embodiment, the current level is set by adjusting the circuit power supply, so that the current level can be set remotely without the need to adjust the reference element directly. The second embodiment is preferably suited for the regulation of beam current in analytical instrumentation. In a third embodiment, the fixed reference element is replaced with a time-varying voltage signal. The current from the cathode then becomes a linear function of the time-varying reference signal. The third embodiment is preferably suited for application as an amplifying element or as the electron source in an emissive display.

Abstract: An electron beam irradiation processing device including an electron beam tube and a current detection unit disposed outside of the window of the electron beam tube. The electron beam tube is adapted to radiate electron beams and has a window and an associated power-source unit that provides a power source. The current detection unit includes at least one of a conductor and a semiconductor covered by an insulating film, and an electron beam level measurement unit having a current measurement unit that measures the current flowing through the current detection unit. The amount of electron beams output from the electron beam tube is controlled by controlling the power-source unit as a function of the current flowing through the current detection unit. In addition, a method of measuring amount of electron beams radiated from an electron beam tube with a window including the steps of providing a current detection unit and measuring amount of electron beams radiated from the electron beam tube by measuring the current flowing through the current detection unit.

Abstract: A lamp having a ceramic molding between a cap and a lamp envelope, the current supply conductors passing through the molding between the cap and the envelope. The conductors pass through separate ducts in the molding, one of the conductors includes a fuse accommodated entirely within the duct, and that duct is sealed at an end adjacent the lamp cap by a coherent mass of material such as a base cement. Flashover from a fuse arc to either the other conductor or the lamp cap is prevented.

Abstract: A filament coil is connected in series with an arc tube to form a self ballasted lamp. An internal starting coil is connected across the arc tube through a bimetal switch, which is normally closed, for energizing the starting coil. When an arc is struck and the tube temperature rises, the bimetal switch opens to cut out the starting coil. A fuse wire is connected across the bimetal switch to facilitate flashing of the filament coil by application of less than rated voltage during evacuation of the lamp envelope when the bimetal switch is normally open because of the elevated temperatures required for glass working and sealing. Upon subsequent application of rated voltage, the fuse wire melts and the lamp operates in its normal manner.
