Patent number: 8193740Abstract: A control circuit for a discharge lamp, which can improve the lighting performance of the discharge lamp while realizing low power consumption, and a light source device are provided. The resistance value of the variable resistor (RC1, RC2) is not switched to the low resistance (R02) for steady discharge at the fourth time t4, but is switched to the low resistance (R02) at the fifth time t5, after lowering of power supply to the filament. With such control, a change in the lamp impedance is absorbed sufficiently by the variable resistor while power supply to the filament is being lowered and, therefore, destabilization of discharge is reduced and the lighting performance is improved.Type: GrantFiled: May 1, 2008Date of Patent: June 5, 2012Assignee: Hamamatsu Photonics K.K.Inventors: Kazuo Ueno, Yoshinobu Ito, Takamasa Tanaka, Koji Matsushita

Patent number: 5822130Abstract: Light radiated from a light source is gathered by an oval mirror. The gathered light is incident on one end of a rod-shaped optical integrator, integrated and made uniform within the optical integrator, and is radiated from the other end of the optical integrator. The light from the optical integrator is diffused and projected on an exposure area of a display tube by a lens system. The lens system presents an astigmatism, thereby forming a first virtual focus and a second virtual focus on its virtual image area. The diffused light is apparently diffused vertically at the first virtual focus and apparently diffused horizontally at the second virtual focus. The first vertical focus and the second vertical focus correspond respectively in position to the positions of the vertical deflection means and horizontal deflection means of the display tube.Type: GrantFiled: March 8, 1996Date of Patent: October 13, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroyuki Nagano, Takashi Inoue, Kazuo Ueno, Shohroh Mochida, Shuji Ueda, Osamu Adachi
