Title: Method and device for lighting of discharge lamp and image display device using the lighting device
Inventor: TAKAYA MANABU
IPC: H05B41/282
Filed: 1993-09-30
Abstract: PURPOSE:To transfer a lamp certainly to glow arc condition by impressing a voltage which suits the glow potential generated in the lamp and which is not excessive. CONSTITUTION:At starting, a steep current flows cyclicly to the primary side coil L1 of a transformer 6, and thereby a high voltage is generated in the secondary side coils L2, L3 of the transformer 6, and capacitors 13, 15 are charged with a high voltage via diodes 12, 15. Each time the charging voltage of the capacitor 15 reaches the voltage to break the discharge gap 16, a high voltage pulse is generated in the secondary coils L5, L6 of another transformer 7 so that a high pressure discharge lamp 21 goes in break-down. If the charge voltage (backup voltage) of the capacitor 13 has risen above the glow potential in the period the same as this operation, a rush current flows from the capacitor 13 to the high pressure discharge lamp 21 in the glow discharge condition, which is thereby transferred to the glow arc condition, so that a voltage which suits the glow potential and is not excessive is impressed on the discharge lamp 21.

Title: Gas laser tube
Inventor: YUTSU TAKAYOSHI
IPC: H01S3/03
Filed: 1987-09-30
Abstract: PURPOSE:To improve stability and reliability of discharge by installing an element for generating magnetic field such as a permanent magnet near the surface of anode electrode to configure so that magnetic field is applied vertically near the outer surface of cathode electrode and in coaxial direction in reference to the electric field which is applied between anode and cathode electrode. CONSTITUTION:When discharge tries to move from a position (a) to an outer periphery of electrode (b) and then further to the outside, force is applied so that it may rotate around the periphery of cathode electrodes 3 and 4 due to the influence of a magnetic field B and is enclosed within the cathode electrodes 3 and 4. Thus, there is no output reduction due to move of discharge to an electrode support part 8 and hence the discharge becomes stable. Also, since electric field (discharge) is applied in coaxial direction, an effect for reducing discharge start voltage is applied, thus realizing a gas laser tube with a stable discharge, long life, and improved reliability. Elements for generating magnetic field 9 and 10 can create the same effect for both permanent magnet and electromagnet.

Title: High pressure gate driver
Inventor: HAYASHI AKIYOSHI
IPC: H02M3/28
Filed: 1990-09-19
Abstract: PURPOSE:To enhance power supply and to prevent fatal failure such as breakdown of main circuit component by employing a dual power supply for a pulse amplifier thereby preventing short circuit fault, occurring when a capacitor in any one power supply is generating gate pulses, from affecting on the gate pulse. CONSTITUTION:Since reverse bias must be applied on the gate of a gate turn OFF thyristor 36 within a short time, the time interval T after provision of an operational command P before rising of an OFF pulse J is set by a smoothing capacitor of about 22muF arranged at the output of a smoothing circuit. On the other hand, since an inverter circuit is operating with high frequency of about 30kHz, ripple current of the smoothing capacitor is high and severe operating conditions are imposed on a capacitor having low capacitance to easily cause self-heating of the capacitor. When a dual power supply system is employed, gate current of the gate turn OFF thyristor 36 is not affected by self-heating phenomenon.
