Title: Analog-digital converter
Inventor: NISHITARUMI TAKESHI
IPC: H03M1/52
Filed: 1983-04-30
Abstract: PURPOSE:To offer a double integral type A/D converter which is capable of raising a resolution in proportion to the number of times of addition by adding continued A/D-converted values. CONSTITUTION:S1 and S2 of a switch 3 are turned off in advance, and first of all, S1 is turned on by a command of a control logical circuit 6, and an analog input Vin is integrated. An output V4 of an integrator 4 increases in the negative direction by an inclination corresponding to the magnitude of Vin. After fixed intervals of time, S1 is turned off, S2 is turned on, and this time, the integrator 4 is integrated in the opposite direction at a prescribed inclination by a reference voltage -Vref. A comparator 5 compares V4 with zero potential, and when it reaches the zero potential, the output is inverted. When V4 is inverted and becomes ''L'', the control logical circuit 6 outputs a signal for turning off S2. In this case, turning-on and -off of S2 are executed in synchronization with a clock pulse by a synchronizing circuit 7, therefore, in case when a point reaching the zero potential exists between a clock pulse CP1 and CP2, turning-off of S2 is extended to the CP2 point, and the remainder of the conversion in the CP1 point is moved in parallel to the CP2 point as it is.

Title: Automatic brightness/contrast adjusting device for scanning type electron microscope
Inventor: AKITA KAZUMI
IPC: H01J37/28
Filed: 1992-03-31
Abstract: PURPOSE:To simplify the operation by stopping the adjustment of automatic brightness/contrast adjusting means when either of manual brightness/contrast adjusting means being operated. CONSTITUTION:When brightness or contrast is manually adjusted during measurement, brightness/contrast adjusting knobs 31 and 32 are turned. Accordingly, brightness/contrast adjusting knob operation detecting circuits 33 and 34 are operated so that a change-over switch 36 is changed, automatically resulting in an manual adjustment state, via an OR-circuit 35. When the manual adjustment is finished and knobs 31 and 32 are stopped, the switch 36 returns to an automatic state, and the adjusted value is measured by a level measuring part 14 and is stored in brightness/contrast target value storing parts 11 and 15. When being changed to an automatic state again, an automatic adjustment is performed based on a new target value. Thus, manual operation of the change-over switch is unnecessary.
