Title: Beam position decision method and device for microbeam apparatus
IPC: H01J37/252
Filed: 1992-03-17
Abstract: PURPOSE:To make direct decision of the positional relation for each beam on a specimen, by forming, with the use of an electronic lens, an image obtained by projection of secondary electrons emitted from the specimen through irradiation of at least two beams thereupon. CONSTITUTION:An electron beam 2 passes through an electron beam deflection plate 4, and an ion beam 3 passes through an ion beam deflection plate 5, to be radiated onto a specimen 1, so that secondary electrons 6 are emitted from the specimen 1. Next, a secondary electron optics unit 10 composed of a drawout lens 11, a focusing lens 12, and drift tubes 13a, 13b causes an emission pattern of the secondary electrons 6 emitted from the specimen 1 to be formed, as a projected image, on a required portion of an electron image detection unit 20. In the unit 20, the secondary electron image projected on the underside of an MCP 21 is amplified with an image distribution thereof being kept as it stands, and thereafter this electron image is converted into a light image by a phosphor plate 22. As a result, luminescent spots 7 in correct correspondence to the secondary electron emission spots on the specimen 1 appear on a plate 22, to enable visual recognition. The positional relation between respective beams on the specimen can be directly decided.

Title: Cartridge-type dispensing container for liquid
Inventor: SEKI TAIICHI
IPC: B05B11/00
Filed: 1993-03-19
Abstract: PURPOSE:To prevent a body and clothes from being soiled with the injected contents remaining in an actuator when an inner container is attached by providing a recessed part for containing liquid around a pump discharge port of the inner container to be exchanged. CONSTITUTION:A cartridge-type liquid distributing container is constituted by a cartridge connection unit 400, a cartridge unit 300 and an outer container 500, and an annular groove provided with a bottom 112 is provided around a discharge port 111 of an actuator driven element 113. Accordingly, when the cartridge 300 is exchanged, viscous liquid remaining in a nozzle of an actuator 410 can be discharged to the annular groove provided with a bottom 112 by pressure drop caused by the increase of peripheral volume generated by the separation of a discharge nozzle terminal 415 of the actuator 410 on the cartridge connection unit 400 side from a discharging port 111 of the actuator driven element 113. Thereby, viscous liquid remaining in the actuator 410 can be recovered in exchanging of the cartridge, so that the inside of the nozzle can be cleaned and the mixing to the different liquid can be avoided.
