Abstract: PURPOSE:To exercise a sky hook damper effect from a low frequency area so as to improve comfortableness by providing a phase control means at a control means for an actuator which delays a phase for a low frequency and advances it for a high frequency against an acceleration detection signal in the vertical direction. CONSTITUTION:Signals from acceleration sensors 28FL to 28RR in the vertical direction at front, rear, right and left are put into a phase delay and advance compensation circuits 40FL to 40RR of a controller 30, and a specified proportional gain is independently multiplied at control gain multiplying circuits 42FL to 42RR against these outputs.

Title: Pulse-beam generating circuit for strobo-scanning electron microscope
Inventor: MIYOSHI MOTOSUKE
IPC: H01J37/28
Filed: 1982-01-22
Abstract: PURPOSE:To produce a high-speed pulse beam stably without causing any shift of the central axis by synchronously supplying pulse voltages, which have different polarities and an equal absolute value of amplitudes, to a pair of deflection electrode plates used for pulse-beam generation. CONSTITUTION:In turning on a beam, since a voltage of 0V is supplied to both of deflection electrode plates 11 and 12, the beam travels straight forward without undergoing any deflection, and a pulse beam having a pulse width corresponding to the duration of the 0V pulse is obtained. When the beam is held on, in the output stage indicated by the figure, since a pulse voltage having a voltage amplitude half that of the conventional pulse voltage is handled, the signal response time can be made sufficiently short compared to the conventional signal response time. As a result, a pulse width obtained when offset voltage develops in the 0V pulse voltage becomes shorter than the conventional pulse width. Consequently, a high-speed pulse beam can be produced stably without causing any shift of its central axis.

Abstract: PURPOSE:To realize high speed operation while preventing a surge voltage from flowing into internal circuit by a constitution wherein discharge takes places in an air gap structure upon application of high surge voltage to a signal input terminal and the surge voltage is bypassed to the earth. CONSTITUTION:Wiring layers connected, respectively, with a signal input terminal IN and a ground line of a semiconductor integrated circuit have end parts forming an air gap structure 2.
