Title: Scan-type charged particle beam microscope
Inventor: NAKASUJI MAMORU
IPC: H01J37/20
Filed: 1991-06-24
Abstract: PURPOSE:To accurately observe a groove bottom or side surface having a submicron or less dimension by applying a high electric field to a sample surface to form a downwardly convex equipotential surface in the interior of a hole having a high aspect ratio. CONSTITUTION:Upon incidence of a primary electron beam upon the bottom of a hole 7 of a sample 6, a secondary electron is emitted from the point of incidence. Since a high voltage is applied from a power source 12 to a detection electrode 4, an equipotential surface is formed near the sample 6 and the internal space of the hole 7 comes to have a downwardly convexed equipotential surface due to the difference in dielectric constant between the sample hole interspace and the sample body. As a result, the secondary electron emitted from the hole bottom receives a force causing it to be directed toward a center of the hole. Small-energy secondary electrons are emitted in large quantity from a residual resist film, in particular, on the bottom of the hole and receives the lens action of the electric field with great influence. Consequently, they go out of the hole via paths 10 without colliding against the wall surface. On the other hand, the reflected electrons and large-energy secondary electrons do not have resist film information so much and impinge upon the hole wall without receiving any lens action. This construction permits secondary electrons, having failed to go out from the hole, to get out of it, thus serving to observe the hole bottom.

Filed: 1993-07-20
Abstract: PURPOSE:To separate fats and oils by vaporizing them from a metallic waste material contg. fats and oils sticking to it with good heating efficiency and to obtain a steelmaking starting material. CONSTITUTION:In this separation, the metallic waste material M contg. fats and oils is charged into the heating furnace 10 and dielectrically heated to a temp. above the vaporization temp. of the fats and oils in a non oxidizing atmosphere. The vaporized fats and oils g1 are entrained in the carrier gas g2 and carried to the cooling chamber 20 and there liquefied or solidified by cooling them to recover them as the fats and oils f1. Optionally, the metallic waste material is blended with a solid material contg. carbon such as coke which is effective in improving the dielectric heating efficiency and acts as a reducing agent. At the time of keeping the heating furnace 10 under a reduced pressure or vacuum, the vaporization of the fats and oils is promoted. The metallic waste material M, from which the fats and oils are removed, is not oxidized or peroxidized and therefore can be utilized as a useful steelmaking starting material. The separated fats and oils f1, which are not burned and accordingly, of which properties and composition remain almost unchanged, can be used as a raw material of fuel, metallic soap, etc.

Filed: 1984-08-30
Abstract: PURPOSE:To allow to manufacture amorphous metal core having less alternation with increased efficiency by applying adhesive material on an amorphous metal lic tape and then winding it onto a rectangular frame to punch out cores from its flat portion by a process which does not introduce temperature-rise thereto. CONSTITUTION:A adhesive material or resin 7 is applied to a tape 1 made of amorphous metal, which is then wounded onto a rectangular frame 6.

Abstract: PURPOSE:To simplify the constitution of a tracking control part by providing an electrical network for generating jumping disturbance, forming thence required three kinds of signals and giving them to a prescribed point of a servo loop. CONSTITUTION:When the tracking control part TSL is turned on by a switch SW to operate its tracking control, a signal JPEN is turned into L, and an output of a 3-state buffer TB is brought under floating condition, and then an adding electric potential voltage via a capacitor C1 from the network 1 for generating jumping disturbance to a adding node N2 between the switch SW and an actuator driving circuit D is turned into zero. On the other hand, at the time of jumping, the switch SW becomes off, and then the signal JPEN becomes H, while a signal JPP is H, and a positive electric potential voltage is impressed to the node N2, and after a light spot attains an accelerative level, the node N2 is impressed by zero electric potential voltage in the same manner and followed by a negative electric potential voltage for braking, to carry out a jumping operation. The reverse jumping is also in the same case, so that the tracking control circuit can be so simply constitute of only one set both for the adding node and for a control line.
