Title: Long arc discharge lamp
Inventor: ODAGAKI TORU
IPC: H01J61/20
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To stabilize an arc by a getter effect appearing shortly after lighting so as to also stabilize an ultraviolet ray radiating strength and to eliminate the necessity of considering the arranging position of a getter by injecting a light emitting material and silicon tetrachloride in a discharge space surrounded by a light emitting tube made of glass. SOLUTION: A straight light emitting tube 1 made of quartz glass is provided to have sealing parts 11 in both ends, and a part surrounded by the light emitting tube 1 is used as a discharge space S. In this discharge space S, a pair of electrodes 2 are arranged to oppose each other along the tube axis of the light emitting tube 1. In the discharge space S, argon is sealed as invert gas, mercury is sealed as a light emitting material, and silicon tetrachloride is sealed as a getter material. As the silicon tetrachloride is ionized instantly by lighting and the temperature of the light emitting tube 1 is increased, H<+> ions and OH<-> ions generated in the discharge space S are absorbed in sequence, a getter effect appears immediately after lighting and thus the arc is stabilized.

Filed: 1983-10-06
Abstract: PURPOSE:To attain reading with gradation and high reproducibility by allowing a signal processing circuit to store a reference signal for a certain period and allowing the circuit to execute division of a picture signal and the reference signal. CONSTITUTION:A reflected light from a reflecting plate of reference density is read from a photoelectric converter 21 as the reference signal just before an original is read and stored in a memory 33.
