Title: Electron beam control device
Inventor: TANAKA TOSHIAKI
IPC: H01J37/305
Filed: 1990-06-01
Abstract: PURPOSE:To vary the electron flow density on a specimen with the deflection angle of an electron beam by making controllable the current density irradiated on the specimen using the deflection angle of the electron beam. CONSTITUTION:An electron beam generated from an electron gun 1 is converged by a lens system, and a specimen 3 is subjected to X-Y two-dimensional scan by a deflecting coil 2. The electron beam makes circular scan over the specimen 3 by flowing the deflection current sin-waveform to X and cos-waveform to Y in the deflecting coil 2. The deflection angle is varied by changing the deflecting waveform current, and spiral scanning can be made. If within the same period of cycle, the outside dia. scanning speed is greater than the inside dia. scanning speed, so that the current density at the outside dia. drops more than at the inside dia. on the specimen 3. Therefore, this method is not favorable in case the specimen is subjected to surface processing. Now, control of the inside dia. scanning speed V1 and outside dia. scanning speed V2 gives an effect of controlling the current density into a uniform or a desired value, and in this case, it is made practicable by controlling the period of cycle in inside dia. scanning and outside dia. scanning.

Filed: 1984-07-09
Abstract: PURPOSE:To omit the swing adjustment in two directions to improve the work efficiency by providing a holding mechanism which positions a light emitting element and a focus lens relatively in accordance with the angular deviation of the emitting light of the light emitting element. CONSTITUTION:When the light emitted from a chip 21 of a light emitting element 22 is converted to a parallel light by a collimator lens 20, the angular deviation in the emitting direction is generated by the loading deviation of the collimator lens 20. This angular deviation is measured preliminarily, and a spherical lens 18 held by metallic parts 19 which have an eccentricity corresponding to this deviation is adjusted to the position most suitable for the light emitting direction (in the rotation direction of an arrow and the Z direction). Metallic parts 19 are adjusted in X and Y directions so that the emitting light has a maximum coupling efficiency for an optical fiber 12. After adjustment, positions marked with black triangles are spot-welded on circles to attach and fix the light emitting element 22 and the optical fiber 12. Thus, swing adjustment is omitted to obtain a high coupling efficiency.

The upper and lower rectangular shapes are formed in such a way as they may be displaced with each other by, for example, 45° in a circumferential direction of the piston 1 at an projected plane of the piston axis. The injection 7 is performed in such a way as it strikes obliquely against a wall surface of the combustion chamber viewed in a top plan thereof while the wall surface of the combustion chamber is inclined by an angle of α with respect to the upper surface of the piston. In order to disperse the injected fuel after its strking against the wall toward the upper surface of the piston, a wall surface of the combustion chamber between the injection points is inclined at an angle of β.
