Title: Inductive plasma generating device
Inventor: AMANO TAKANOBU
IPC: H05H1/28
Filed: 1987-11-26
Abstract: PURPOSE:To prevent burn of a torch and shortcircuit of an RF coil by forming a quartz tube in a double structure, circulating cooling water inside it and providing a cylindrical light shielding means for shielding light from generated plasma. CONSTITUTION:A light shielding means 10 for shielding light produced at plasma 2 to prevent it from going to the external is disposed inside a quartz tube 1 of thin metal or insulating matter formed cylindrical in a double structure. If the light shielding means 10 is formed of metal, a slit 10a is formed along the axis of the cylinder. Cooling water is let to flow through the double quartz tube 1. Light produced from plasma can thus be prevented from leaking to the external. Burn of structural parts of a torch by radiant heat is therefore eliminated, and leak of UV is also eliminated, so production of ozone around the quarz tube is prevented. Shortcircuitting of an RF coil 2 by ionization around the circumference can thus be prevented, and stable action can be achieved.

IPC: H02J1/00
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To provide a circuit and method for preventing an overvoltage which may reduce the gate voltage of a transmission gate and may damage or affect the reliability of the transmission gate. SOLUTION: A transmission gate exists in a charge pump circuit 41 and is connected to a capacitor for generating a higher voltage than a power supply voltage. Buffers 44 and 45 receive a control signal and are connected to the gate terminal of the transmission gate. The buffers 44 and 45 includes a power supply terminal which are connected to a variable voltage reference 43. The variable power supply reference 43 generates a voltage for reducing the gate voltage of the transmission gate, when the output voltage of the charge pump circuit reaches a specific voltage. The variable voltage reference 43 narrows the voltage range between logic levels supplied by the buffers 44 and 45 and protects the transmission gate against overvoltages.
