Title: Ion laser apparatus
Inventor: ISOBE KANICHI
IPC: H01S3/038
Filed: 1986-03-20
Abstract: PURPOSE:To obtain an ion laser apparatus wherein no noise is generated in a laser output and the filament of a cathode has a long life by lighting the cathode filament by using DC current and periodically changing over the polarity of the DC current. CONSTITUTION:A power supply circuit lights the filament of a cathode 13 by a lighting DC power supply 41, which is connected to the cathode 13 via a polarity changeover switch S1. One terminal of a discharging DC power supply 33 is connected to the cathode 13 via an input terminal changeover switch S2 and an anode 15 is connected to the other terminal of the discharging DC power supply 33. The power supply 41 supplies DC current to the cathode 13 to heat the filament and the power supply 33 applies a voltage to the cathode 13 and the anode 15 to cause a discharge in a discharge tube 1, ionizing and exciting rare gas atoms to perform a laser oscillation. In the laser oscillation, the switch S1 is automatically changed over at constant time intervals to change over the polarity of the voltage applied to the filament. Such operation changes over the potential difference in the filament at constant time intervals and can prevent the deterioration due to plasma from being concentrating at one end.

Title: High pressure sodium lamp
Inventor: YOKOME HIROYOSHI
IPC: H01J61/06
Filed: 1986-03-26
Abstract: PURPOSE:To improve the life time of a lamp while maintaining excellent light color and color rendering characteristics by using yttrium oxide Y2O3 as the electron emitting material of the electrode. CONSTITUTION:Yttrium oxide Y2O3 in used for the electron emitting material 4 of the electrodes 7a, 7b for a high pressure sodium lamp of high color rendering. Yttrium oxide Y2O3 is more excellent in all aspects of melting point, the evaporativity and the work function than other oxides, hence it suppresses the blackening of the luminous tube and the exhausting of the electron emitting material due to the evaporation and the sputtering of the electron emitting material. Further as it release free oxygen most hardly, the reaction of oxygen with sodium is low, and the loss of sodium can be suppressed most effectively. Thereby the increase of the lamp voltage and the deterioration of the luminous flux can be suppressed to improve the life time of the lamp while maintaining excellent light color and color rendering characteristics.
