Abstract: PURPOSE:To enable observation even if the observer can not observe at specified observing time and to simplify the construction, by switching and storing the fall within a given time sequentially and automatically to the stored bottle. CONSTITUTION:The rain gauge main body introduces the rain received with the water receiver 1 to the storage bottle 6 through the water inlet 2, the direction of the water inlet tube 2 is turned by a given angle every observing time by means of a switch device, and the rain is stored to separate water bottles every one time. The switching mechanism is constituted that the reduced gear is directly coupled to the DC motor and the direction of water introducing tube is turned. Further, the servo motor is used for the control of the rotating angle, and the size of rotating advanced angle of one time is 360 deg./X, by taking the number of switchings as X,  and when this angle is exceeded, the motor is instantly reversed for braking. Thus, simple and easy handling is achieved for the rain gauge.

Abstract: PURPOSE:To suppress the electrification of a work or a sample by feeding electrons to the work or the sample in the vacuum from an electron source with nearly the same potential. CONSTITUTION:A sample 7 and an electron source filament 2 are kept at nearly the same potential. If the sample face 8 is an insulator or the like, secondary electrons 9 are generated by the radiation of a charged particle beam 1, the sample face 8 is charged.

When only about 10V is applied across the filament 2 and the sample 7 by a bias voltage source 4, a sufficient quantity of electrons are transported to the vicinity of the sample 7. When the scattering of a filament material is to be avoided, electrons 6 are deflected by an deflecting electrode or the magnetic field. No metal cover is required for a nonconducting material in a scanning type electron microscope, the charged particle beam 1 is prevented from being deflected near the sample by the electrification of the sample 7 in other devices, the dielectric breakdown of the sample 7 can be prevented in an ion implanting apparatus according to this constitution.
