Inventor: KOSHISHIBA HIROYA
IPC: H01J37/22
Filed: 1989-03-10
Abstract: PURPOSE:To enhance a detection speed of a scanning detector so as to shorten a detection time by processing an image detection signal on the basis of the result of specific mathematical processing of the response characteristics of an image detection system and restoring the deterioration due to a delay of the signal. CONSTITUTION:Electron beams 15 produced and accelerated by an electron gun 1 are focused on a sample 4 by an electron lens 3. And also a scanning coil 2 driven by means of a scanning signal produced by a deflection circuit 9 synchronized with a synchronous circuit 10 makes deflection scanning on the sample 4. The electron beams 15 passing through the sample 4 are incident on a scintillator 5 and light generated thereon is incident to a photoelectron multiplier 7 via a light guide 6. The output signal therefrom is inputted to a restoration circuit 13, via an amplifier 8, an AD converter 11 and a smoothing circuit 12, to restore the deterioration of the output signal and the restored signal is displayed by a display circuit 14. In the restoration circuit 13, the response characteristics of an electron detection system is approximated by a proper transfer function. An image detection signal is then processed on the basis, of an equation obtained by way of reverse Laplace transformation of a reverse function of the transfer function to restore the deterioration of the image due to a delay of the image detection signal.

Title: Switching regulator
Inventor: NAKAMURA SHIGEO
IPC: H02M3/28
Filed: 1989-03-13
Abstract: PURPOSE:To suppress generation of a noise by connecting a diode, in which its connecting point side is negative, between a point between a first diode and an inductance and a connecting point to one electrode of a primary winding of a transformer. CONSTITUTION:Since a current flowing to an inductance L passes a second diode D2 when switching means Q is again closed, a reverse current to that so far flows during the reverse recovery time of the diode D2 even after the current of the inductance L is attenuated to 0 A due to charging of a capacitor C or a reverse current to a power source. Since this current is abruptly attenuated to 0 A after the reverse recovery time of the diode D2 is elapsed, the current flowing to the inductance L so far is returned to the power source through a third diode D3, and a voltage applied to the diode D2 is clamped to the power source voltage.
