摘要： Dehydrating decomposition of compound (I), i.e. gem-diol, hemi-acetal or hemi-ketal, by contact with sulfuric acid gives a carbonyl compound (II). ##STR1## Disclosed is a two-stage process in which the first stage is the contact of compound (I) with sulfuric acid at 90.degree.-140.degree. C. so as to partly decompose and dehydrate the compound (I), permitting the concentration of sulfuric acid to become lower than 93 wt. % but not lower than 65 wt. %, and the second stage is the contact of the product of the first-stage reaction with concentrated sulfuric acid at a temperature not higher than 60.degree. C., preventing the concentration of sulfuric acid from becoming lower than 93 wt %. For example, hexafluoroacetone is obtained from a hydrate thereof by this process using only a small amount of sulfuric acid.

摘要： Crude hexafluoroacetone (HFA) hydrate containing chlorofluoroacetone(s) hydrate(s) as impurity is purified by adding an alkali metal hydroxide and maintaining at an elevated temperature, preferably at 100.degree.-110.degree. C., to thereby cause decomposition reaction of every chlorofluoroacetone hydrate with the alkali metal hydroxide, followed by neutralization of an excess portion of the alkali metal hydroxide. Alkali metal hydroxides, which readily react with anhydrous HFA, react preferentially with chlorofluoroacetone hydrates but hardly react with coexisting HFA hydrate.

摘要： A lens holding frame holding a lens in a lens barrel is arranged, and a contact member extending therebelow is in friction coupling with a driving axis. By applying driving pulses having such a waveform that includes a moderate rising portion followed by an abrupt falling portion to a piezoelectric element, the holding frame is moved along the direction of the optical axis. An index provided at the holding frame is exposed through a slit of lens barrel, and from the position of the lens on the holding frame, information with respect to the distance to the object is displayed. Detection of the position of the holding frame is performed by a position sensor of ferromagnetic thin film magneto-resistive element type (MR sensor) so as to obtain positional information of the lens on the holding frame based on the detection signal, and the obtained information may be displayed on a liquid crystal or other display portion provided on the lens unit or on a camera body.
