20130009070 | ELECTROSTATIC LENS FOR CHARGED PARTICLE RADIATION - Provided is an electrostatic lens for charged particle radiation with a lens performance relatively comparable to that of a magnetic type lens. A plurality of electrodes arranged on the incident side of charged particles form a first electric field area, wherein orbit radii of the charged particles are reduced without exceeding, on the way, the initial orbit radii that are orbit radii at the incident time, and a second electric field area, wherein force in the direction advancing in parallel with a central axis is applied to the charged particles that have passed through the first electric field area. A plurality of electrodes arranged on the projection side form a third electric field area, wherein the orbit radii of the charged particles do not exceed the initial orbit radii on the way and are curved to intersect with a central axis at angles larger than orbit angles defined with respect to the central axis of when the charged particles are projected from the second electric field area. | 01-10-2013 |

20090232924 | SHAPE-FORMING SHUTTER APPARATUS AND SHUTTER PIECE THEREOF - Disclosed is an shape-forming shutter apparatus including a plurality of shutter pieces, each having an shaping surface and a sliding surface, which are arranged in a circle with the shaping surface of each shutter piece being slidably in sliding contact with the sliding surface of the neighboring separate shutter piece, and the shape-forming shutter apparatus being capable of dilating and contracting an opening part surrounded by the shaping surfaces respectively of the plurality of shutter pieces. The shape-forming shutter apparatus includes pressure contact biasing means for always keeping the shaping surface of each shutter piece and the sliding surface of the neighboring shutter piece slidably in pressure contact with each other. The pressure contact biasing means is a ring-shaped elastic member for biasing the shutter pieces equally in such a direction to close the opening part. The elastic member is stretchingly wound around the shutter pieces in an end of each shutter piece, which end is separate away from the other end thereof where the shaping surface of the shutter piece and the sliding surface of the neighboring shutter piece intersect each other. | 09-17-2009 |

20110030203 | ELECTRONIC COMPONENT MOUNTING APPARATUS - The invention is directed to an electronic component mounting apparatus which is applicable to a case in which component feeding devices need not be provided on both sides of a carrying device respectively for reasons of types of electronic components or a setting space and increases an operating rate of a beam to enhance production efficiency. An electronic component mounting apparatus has a carrying device carrying a printed board, a component feeding device supplying electronic components, a pair of beams movable in one direction by drive sources, and mounting heads each having suction nozzles and movable along the beams by drive sources. The component feeding device is provided on only one side of the carrying device, and the suction nozzles provided on each of the mounting heads pick up electronic components from the component feeding device and mount the electronic components on a printed board by moving the mounting heads provided on both the beams between the printed board on the carrying device and the component feeding device by driving the drive sources respectively. | 02-10-2011 |
