Title: Steel pipe end face grooving machine
Inventor: MAEDA YOICHI
IPC: B21D17/04
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To prevent circumferential variance of depth and width dimensions of an annular groove and spiral deviation by rotating a face plate, dies, copying rolls and an air cylinder along an outer peripheral direction of a steel pipe by means of an electric motor. SOLUTION: A steel pipe 1 is fixed and pressed with dies 10 having copying rolls 11, thus making it possible to form an annular groove in the outer surface of the steel pipe 1 at a constant dimension regardless of roundness of the steel pipe 1. Since a face plate 14 is rotated with the steel pipe 1 fixed, a good annular groove can be formed regardless of the extent of bending in the longitudinal direction of the steel pipe. In order to press down the dies 10 and the copying rolls 11 onto the outer surface of the steel pipe, an air cylinder 15 is installed to the face plate 14. The face plate 14 is rotated by the electric motor 19 via face plate rotating bearings 20 and gears. It is, therefore, possible to form annular grooves on the outer surface of the steel pipe efficiently and accurately regardless of the roundness of the steel pipe 1.

Title: Ion beam device
Inventor: KASAHARA HARUO
IPC: H01J37/244
Filed: 1987-07-14
Abstract: PURPOSE:To enable secondary ions to be detected efficiently without deteriorating a detector by detecting secondary ions generated from a conversion plane after injecting the secondary ions generated from a target into the secondary electron conversion plane kept equal in potential to the objective lens side. CONSTITUTION:Secondary electrons generated with the irradiation of ion beams to a target 10 are drawn back to the target 10 since the potential of the target 10 is higher than the potential on the objective lens side. However, the secondary ion generated from the target is accelerated with 27kV and enters an electric field softening electrode 16 and a plate 14 in the earth potential. Secondary electrons are generated from the plate with the injection of the secondary ions to the plate 14. This secondary electrons are invited to a microchannel plate 17 by the potential difference between the plate 14 and the microchannel plate 17 and detected there. Hereby, the secondary ions from the target can be defected without causing deterioration in the detector.

Title: Electronic flood gun
Inventor: ANTONII RENAU
IPC: H01J37/317
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To eliminate positive electric charge which charges a semiconductor wafer during ion implantation by installing a diode containing a cathode and an anode, a means for introducing a rare gas to a region adjacent to the cathode, and a means for applying adjustable bias voltage to the cathode. SOLUTION: Passing a grid 64, a rare gas from an emission line 66 flows as shown by an arrow 84 to produce a high pressure region 85 of the rare gas in a flood gun 50. Electrons with high energy emitted from a filament 63 come into collision with Ar gas and are multiplied as illustrated in a figure 86. As a result, the amplified and flowing electron flow with low energy emitted through a low-pressure region in the peripheral part is drawn into an ion beam and flows to a wafer, due to an ion beam field combined with an electric field 83 generated by suppressing electrodes. At the same time, a magnetic field 82 generated by beam-stopping magnets inhibits flowing electrons from flowing to the wafer and the suppressing electric field 83 prevents secondary electrons from entering an accelerating system.
