Abstract: It is intended to provide a method whereby various kinds of microcapsules, which are usable in, for example, a gene vector, can be produced in a small amount. This production method comprises: feeding a fluid containing a substance to be encapsulated into at lease one (13) of material-feeding microchannels in a substrate in which these material-feeding microchannels (12, 13, 14) and a reaction microchannel (18) connected to these material-feeding microchannels are formed; feeding an envelop-forming fluid containing a material for forming envelopes into at least one of the other material-feeding microchannels (12, 14); and allowing the envelope-forming fluid and the fluid containing the encapsulated substance that converge in the reaction microchannel from each material-feeding microchannel to flow through the reaction microchannel while continuously maintaining the interface between the fluids formed at the confluence thereof.

Abstract: In a VTR signal processing circuit, a first reproduced color under signal and a second reproduced color under signal obtained by delaying by one or two horizontal period in synchronism with a predetermined clock signal are supplied to the first and second frequency converter circuits 1 and 2 respectively, a frequency signal having frequency 2n times that of a carrier used in frequency conversion for converting a frequency of the reproduced color under signal into a frequency corresponding to a standard color signal is produced by an oscillator circuit, this oscillation frequency is divided such that it becomes the above mentioned carrier frequency, four carriers having phases 0 degree, 90 degrees, 180 degrees, and 270 degrees respectively are produced, the four carriers are selectively output and supplied to the first and second frequency converter circuits 1 and 2 such that an output signal of the first frequency converter circuit 1 and an output signal of the second frequency converter circuit 2 become in p

Abstract: A facsimile transmitting and receiving apparatus comprises a facsimile unit having no single-action or abbreviated dialing function connected to a telephone set which provides an automatic dialing device for transmitting a dial single by the single-action dialing or abbreviated dialing operation and a signal processor for automatically outputting a selection control signal for executing facsimile transmission after call originating operation and operates with a power supply voltage supplied through a telephone line.
