Title: Mis transistor
Inventor: FUKUMA MASAO
IPC: H01L29/40
Filed: 1984-06-15
Abstract: PURPOSE:To obtain the title element of high withstand voltage by a method wherein the gate electrode located at a point only one moved from the gate electrode closest to the source toward the drain, of gate electrodes divided into two or more along the channel direction, is kept at a constant potential, and the gate electrode closest to the drain is brought into contact with the drain or into capacitance coupling. CONSTITUTION:Several separated gate electrodes 5, 6 and 7, 7... are formed on an extended drain 10, each of which is firmly coupled in capacitance with adjacent ones by means of coupling capacitors 8. It is possible to gradually increase the potential of each gate electrode on the drain 10 from the side close to the source 2 to the side of the drain electrode. Proper selection of each coupling capacitance enables the control of the way of increasing the potential. Therefore, the potential corresponding to the space distribution of channel potentials can be set to each gate electrode, and it becomes to set low the electric field in a gate oxide film while the role of a field plate is played. Besides, since each gate electrode is just coupled in capacitance, the leakage current in the drain can be kept very small.

Title: Discharge-pumped pulse laser device
Inventor: NAKATANI HAJIME
IPC: H01S3/225
Filed: 1989-05-17
Abstract: PURPOSE:To set both the voltage rising sharpness of corona discharge and that of main discharge at high values by a method wherein, after a first charging capacitor and a saturable reactor are combined and a voltage for corona discharge has risen, inductance of the saturable reactor is decreased. CONSTITUTION:A first and a second charging capacitors 9, 10, 11 of an excimer laser device are charged via a charging reactor 18. In this charging process, the iron core of a saturable reactor 19 is in a saturated state to one polarity. At the time t=0, the spark gap of a switch 8 is discharged, thereby starting the discharge of each of the capacitors 9, 11, 12. The direction of current flowing in the reactor 19 at this time becomes inverse to the direction at the time of charging. The iron core turns to the unsaturated state; the reactor functions as a large capacity reactor, and restrains the discharge of the capacitor 9; the rise of discharge of t he capacitor 12 is slowed; the amount of preliminary ionization generated by corona discharge 16 is increased. Thus the capacity of the reactor 19 is increased.
