Title: High-brightness discharge lamp
Inventor: MATSUMOTO HIDEYUKI
IPC: H01J61/34
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To prolong the lifetime of a high-pressure sodium lamp. SOLUTION: This high-pressure sodium lamp equipped with two light emission tubes 100 which are accommodated in respective inner tubes 200. Even if one light emission tube generates leakage to cause gas generation, it remains inside the inner tube and does not leak to the outer tube 300. In this case, the other light emission tube continues lighting, which prolongs the lifetime of the high- pressure sodium lamp wherein the risk of flame failure likely in the final period of lifetime can be eliminated.

Abstract: PURPOSE:To widen a speed range, in which torque control is effected, by a method wherein a current is controlled correctly with respect to a current command, proportional integration control of a speed is effected with respect to a speed limit command and integrating operation control method is switched depending on a control condition. CONSTITUTION:During limiting a speed, integrating control is effected by an integrating controller 5 through a time constant and the added value of the output of the integrating controller 5 and an error of speed between a speed limit command 1 and a speed feedback 2 becomes an input for a speed control gain 7 while a speed control output 8 is obtained by multiplying the speed control gain 7. Subsequently, the speed control output 8 is compared with a torque command 9 in a runaway preventing unit 10 to select a command for a current control unit 11. On the other hand, during controlling a torque, the reverse polarity of the output of the integrating control is inputted into the integrating controller 5 and the output of the integrating controller is reduced by the time constant whereby processing is effected at all times during controlling the torque in an area lower than a stationary difference. In the area of the stationary difference, the processings are repeated alternately during controlling a torque and during controlling a speed.
