IPC: G03B9/02
Filed: 1987-10-09
Abstract: PURPOSE:To surely prevent light shielding blades from springing out onto a photographic optical path from the diaphragm opening state by surely restricting the movement of a light shielding blade rotating ring, which controls the diaphragming state of light shielding blades, in the initial position by magnetic attraction. CONSTITUTION:When light shielding blades 22 open a diaphragm aperture, the diaphragm aperture is given by the inside peripheral edge of a light shielding blade rotating ring 23 and light shielding blades 22 do not appear on the inside of the inside peripheral edge of the light shielding blade rotating ring 23, namely, on the photographic optical path. In this state, a stopper part 23f of the light shielding blade rotating ring 23, namely, a permanent magnet 27 fixed to this part 23f is engaged with an electromagnet device fixed to a rotating ring retaining plate 24. Consequently, the magnetic attraction of the permanent magnet 27 acts upon a yoke 29 of the electromagnet device to prevent the light shielding blade rotating ring 23 from moving away from this position. Thus, light shielding blades are surely prevented from springing out into the photographic optical path from the diaphragm open state.

Title: X-ray spectrometer
Inventor: KAWABE KAZUYASU
IPC: H01J37/20
Filed: 1987-10-09
Abstract: PURPOSE:To conduct an accurate analysis while maintaining an excellent wavelength resolution, by detecting the amount of slippage of a sample from a reference position in the case when an X-ray detection signal is at a peak, by means of a transfer distance detecting means. CONSTITUTION:An X-ray spectrometer is subjected to convergence at a convergent point 7 in every step transfer. An X-ray converged at the convergent point 7 in every step transfer is monitored successively by an X-ray detector 9, and thereby a spectral peak of the X-ray is observed in the vicinity of a specified wavelength. In the case when the peak is not detected in this stage (in the case of NO), a return is made to the initial stage and the scanning of a spectral crystal is continued. When the peak is detected, it is judged whether or not a spectral distance lp(1) in the preceding stage is included in a correction region out of regions on the transfer axis of the spectral crystal, in which the amount of a change in the intensity of a detected X-ray in relation to a unit transfer amount of a sample in the direction of the optical axis of an electron beam is larger than the amount of the change in the intensity of the detected X-ray in relation to a unit transfer amount of the spectral crystal on the axis of straight advance. In the case when lp(1) is not included in the correction region, a spectral wavelength lambda and others are computed and a peak search is ended.
