    摘要: An electronic timepiece equipped with an alarm system whereby an external control member is actuated a desired number of times or for a desired time duration causing a count to be set into a first counter. Subsequently, when an alarm is generated, an identical count value must be set into a second counter by actuating an external control member for the same number of times or for an appropriate time duration in order to shut off the alarm. Possibility of the user shutting off the alarm signal and then falling asleep again is thus greatly reduced. A snooze switch control function can also be easily incorporated.

The process includes a first reaction step of allowing a specific chlorine-containing compound to react with a fluorinating agent under increased pressure in a gas phase in the presence of at least one fluorination catalyst selected from the group consisting of chromium oxide and fluorinated chromium oxide, and a second reaction step of heating the product of the first reaction step in a gas phase under a pressure lower than the pressure in the first reaction step. The process of the present invention can produce a fluorine-containing alkene with a high selectivity with the use of a catalyst that can be easily handled, while suppressing production of by-products that cannot be easily converted into the target or separated.
