Abstract: In a portable facsimile apparatus according to
this invention, each recording paper (or each document

operation. In a case where the portable facsimile
apparatus needs additional recording paper (or an
additional document) to be set by an operator during
image reception or image transmission, the portable
facsimile apparatus so informs the operator, while the
apparatus delays shifting following image reception or

disclosed. A micropipette (4) is formed having an inside diameter no larger than the size of
the drops to be formed. The micropipette is connected to a system (14) capable of

capillary action or from the negative pressure developed by the system. The
micropipette is then positioned to deliver liquid to an intended location on a surface.
To deliver the liquid, a positive pressure is developed within the micropipette (4). The
positive pressure forces a micron-sized or smaller drop of liquid out of the
micropipette. The method can be used to form micron-sized or smaller drops of
adhesive for fixing in place various structural members that form microdevices.
