Title: Preparation of g-acid
Inventor: IZUHARA MASATAKA
IPC: C07C67/00
Filed: 1982-02-26
Abstract: PURPOSE:To obtain G acid in high yield without using conc. sulfuric acid, by reacting a specific amount of betanaphthol with chlorosulfonic acid. CONSTITUTION:1mol betanaphthol is reacted with 2-2.5mol, preferably 2.1- 2.3mol chlorosulfonic acid in a solvent such as tetrachloroethane, trichlene, etc., at 40-120 deg.C, preferably at 50-100 deg.C to give G-acid. In the conventional sulfonation wherein betanaphthol is reacted with conc. sulfuric acid or fuming sulfuric acid or their mixture; conc. sulfuric acid is diluted with water formed by the reaction, so that it has a defect of cessation of the reaction. When excess conc. sulfuric acid is used to improve the yield, the treatment of waste water of a large amount of unreacted sulfuric acid becomes a problem. This method has no these defects, and the desired substance is obtained industrially advantageously.

IPC: G03F7/20
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To make the electric field leaking onto a sample surface sufficiently small by setting the first electrode facing a sample at the equipotential to the sample. SOLUTION: The lower electrode 6 is set at the equipotential to the sample 8 and a negative voltage based on the potential of the electrode 6 as reference is applied on the upper electrode 4. The electric field leaking onto the sample surface is made small and the mispositioning of a beam 1 occurring in the electric field change near the sample according to the movement of the sample 8 is made sufficiently less by setting the electrode 6 and the sample 8 at the equipotential. The quantity of the secondary electrons entering the beam passage in an objective lens 2 and a deflector 3 is decreased by the impression of the negative voltage. The quantity of the reflected electrons entering the beam path is decreased by diminishing openings 5, 7.  As a result, the charge quantity accumulated on the inside surface of the beam passage is decreased and the degradation in the beam position accuracy by a charge-up is suppressed.

An intermediate frequency signal outputted from the detector 4 is inputted to a demodulation system via an amplifier 6. On the other hand, the intermediate frequency signal is fed also to a filter 6 and the side band of the low frequency side of the intermediate frequency signal extracted by the filter 6 is given to a frequency discriminator 7. The discriminator 7 applies frequency discrimination to extract the frequency control signal thereby controlling the oscillated frequency of the light source 2.
