Abstract: A blanking deflector according to an embodiment includes: a first electrode comprising a first insulator, a first material film coating all surfaces of the first insulator and having lower resistance than the first insulator, and a first low-resistance film coating part or all of surfaces of the first material film and having lower resistance than the first material film; and a second electrode comprising a second insulator, a second material film coating all surfaces of the second insulator and having lower resistance than the second insulator, and a second low-resistance film coating part or all of surfaces of the second material film and having lower resistance than the second material film, wherein the blanking deflector controls whether to irradiate a specimen with a charged particle beam by causing the charged particle beam to pass between the first electrode and the second electrode.

Abstract: A depositing method of wall concrete, in which unset concrete is deposited in a form, includes the step of disposing a non-hygroscopic soft sheet which has a large number of hollow projections or ridges on an inner surface of the form being deformable when lateral pressure is applied thereto by the hardening of the concrete.
