Patent JP-H03205749-A (JP)
Title: Beam concentration compensation device
Inventor: ROGAA KASANOBA ARIGU
IPC: H01J29/70
Filed: 1990-11-26
Abstract: PURPOSE: To prevent the concentration failure caused by a floating defected magnetic flux near an electron gun body structure by introducing a part of leakage flux to the vicinity of the outlet end o the electron gun structure, and adding a barrel magnetic field component to the magnetic field so as to interact it with an electron beam. CONSTITUTION: The interaction between an electron beam and a leakage vertically deflected magnetic field 22 within an electron gun structure 14 can be reduced by forming the first acceleration electrostatic focusing electrode 23 of the electron gun body structure 14 by use of a material having a high permeability. Namely, since the magnetic field gets into and out through the relatively narrow end part of a bent part 36, the magnetic force line is effectively collected in this part, but the magnetic field is swollen in the space to form a barrel magnetic. This barrel magnetic field gives an extending effect to the electron beam to compensate the excessive concentration of beam caused by the permeable electrostatic focusing electrode 23. Thus, the focusing failure resulted from a leakage deflected magnetic field can be reduced.

Filed: 1993-12-17
Abstract: PURPOSE:To reduce the shaping frequency and replacing frequency of a grinding wheel by feeding the grinding wheel in the groove axial direction while the rotation axis of the grinding wheel is inclined in the groove axial direction against the plane perpendicular to the groove axis of a ball groove in the method for grinding the ball groove formed on a work with the grinding wheel.

Title: Charged particle beam takeout device
Inventor: NAKADA SHUHEI
IPC: G21K5/04
Filed: 1987-12-18
Abstract: PURPOSE:To suppress generation of a residual magnetic field by providing matching resistance having different value from characteristic impedance of a transmission line. CONSTITUTION:Matching resistance 6A fitted up at the termination of a transmission line 4 is made to have different value from characteristic impedance of the transmission line 4. Accordingly, a refraction wave is generated in the spot of the matching resistance 6a and this reflection wave is again reflected in the DC supply 1 so that the wave of the same signal is reflected for being transmitted toward an electromagnet. This reflection wave is again reflected by matching resistance 6A at the termination of the transmission line 4 so that the positive-and negative currents reciprocally flow through the electromagnet. Thereby, a magnetic substance consisting the electromagnet 5 receives a demagnetization effect so as to prevent generation of a residual magnetic field.
