Title: Variable focus optical system
Inventor: JIYAN KUROODO PERAN
IPC: G02B7/10
Filed: 1988-06-03
Abstract: PURPOSE: To reduce the complicatedness of a system and to reduce cost by making only either of two movable lenses have four single element lenses used for temperature focusing and finite distance focusing and providing a means individually controlling the movement of the movable lens. CONSTITUTION: The lenses L1 and L4 are fixed and the lenses L2 and L3 are movable. The final focusing adjustment of two lenses L1 and L4 is performed during the assembly of the optical system so as to compensate a rotational error made at the time of producing the lens and the positional error of a barrel to which the lens is attached. The lenses L2 and L3 are moved irrespectively and the temperature focusing and the finite distance focusing of the optical system aye corrected by the single lens L3. Such correction is performed individually. Thus, the system is simplified and the cost is reduced.

Abstract: PURPOSE:To make it possible to always keep the height of the liquid level of a rinse liquid cell constant, by attaching a rinse liquid tank having a vacuum part formed to the inner upper side thereof above the liquid level of the rinse liquid cell so as to contact the lower opening thereof with a rinse liquid in a liquid seal state. CONSTITUTION:A rinse liquid tank 16 is attached above the liquid level of a rinse liquid tank 1 so as to contact the lower opening 20 thereof with the liquid level in a liquid seal manner and a vacuum part 15 is formed to the upper part therein. In this state, when a rinse liquid 14 is sucked up by a capillary tube 2 and the liquid level of the rinse liquid 14 is slightly lowered from the lower opening 20, air enters from the formed gap to increase the vacuum part 15 and the rinse liquid 14 in the tank 16 flowed into the cell 1. Thereafter, the liquid level is again raised to bring the lower opening 20 under the liquid level and balance is taken to stop the inflow of air. Every when the rinse liquid 14 is sucked up by the tube 2 and the liquid level is lowered, this operation is automatically repeated and the height of the liquid level of the rinse liquid 14 is always kept at position slightly higher than the lower opening 20 in a balanced state to always hold the liquid level of the cell to a constant height.

IPC: B07C5/342
Filed: 1988-06-04
Abstract: In order to analyse metal particles for their chemical composition and to obtain a sorting signal, a method and device are proposed in which the particles (1) are subjected to a pulsed laser beam (6, 8, 9, 10) and partially vaporised to form a plasma, purified thereby and subsequently the purified location is partially vaporised by means of a pulsed laser beam to form a plasma and the spectral lines of the plasma are used to identify (11, 14) the metal particles. The required measuring frequency of 30 particles per second can easily be attained and exceeded when a specific narrow waveband or a specific wavelength is filtered (11) out of the total radiation emitted by the plasma, and when the ratios of the intensities of the filtered-out component beams are formed and from the values of these ratios a sorting signal is obtained by comparison with adjustable limiting values. Moreover, the rate of measurement can be improved owing to the fact that the component beam is used for comparison only during a specific time interval.
