摘要:
The present invention relates to a camera with the main circuit boards and the sub-circuit boards comprising electrical circuit constructions having resistance-conductor laminated constructions so designed that the insulating support on which a resistance material layer and a conductor material layer are laminated are processed by means of selective etching. This is done in such a manner that the resistance members are constituted with the resistance material layer while the conductor parts such as wiring, terminals and so on are constituted with the conductor material layer.

The control part of the slide member in contact with electrodes of a variable resistance with resistance members and a plural number of electrodes is made larger than the insulation part between two adjacent electrodes so as to secure the conductivity between the electrodes and the slide member. The form of the slide member and the space provided between each electrode part with respect to other such parts satisfy a predetermined mathematical relationship.

A process for producing a fluorinated ester through a small number of steps, is presented. The process for producing a fluorinated ester, comprises a transesterification step in which RAF—COOCF2—RAF and RA—CH2OH are subjected to a transesterification reaction to obtain RAF—COOCH2—RA, and a fluorination step in which the obtained compound is fluorinated to obtain a reaction product containing RAF—COOCF2—RAF. Here, in the formulae, RA is a monovalent organic group, and RAF is the same group as RA or a monovalent organic group obtained by fluorination of RA.
