Abstract: A method for simply and efficiently separating substances by utilizing a specific flow behavior in a non-turbulent flow, i.e. a laminar flow, in a micro-channel is disclosed. A mixed solution containing at least two kinds of solute molecules which are different from each other in molecular weight and/or molecular sharp, or at least two kinds of solutions containing their respective solute molecules are flowed into a micro-channel to form a non-turbulent flow. A physical action is given to each molecule by changing the state of flow, thereby causing different behaviors among the different solute molecules. By utilizing this behavior difference, molecules of a specific kind are gathered in a specific region in the channel for separation.

Abstract: A method of chemically reacting two or more reactants which react one another, which comprises fixing molecules of the reactants to fluids and supplying them to a microchannel to efficiently conduct the chemical reaction based on the molecular structure or molecular orientation imparted to the microchannel or on the function of changing the distributed state of molecules in a solution.

Abstract: A novel method for analyzing a specimen molecule with high accuracy through a simple operation by forming a laminar flow of a specimen molecule containing solution and a complex forming molecule containing solution in a microchannel and measuring the variation of the degree of diffusion of complexes each composed of a specimen molecule and a complex forming molecule in the laminar flow. The complex forming molecule is fluorescent, and the variation of the degree of diffusion of the formed complexes is measured from the distribution of intensity of fluorescence. The degree of diffusion of the formed complexes can be quantitatively determined by comparing it with a calibration curve preliminarily defined.

Abstract: The invention is a driving circuit for an electrostatic recording head which reduces the turn-on time, the storage time and the turn-off time of the driving circuit output pulses. Mutually complementary first and second transistors are connected with their collectors in common. A first driving signal is supplied via a coupling capacitor to the base of the first transistor, and is also supplied to the base of the second transistor. High voltage is supplied to the emitter of the first transistor. The output signal is obtained from the interconnection of the common collectors. The first driving signal has three sequential levels, two of which occur within the time period when the recording picture signals are supplied. The first level e.sub.2 is the highest and occurs during the beginning portion of the recording signal and the second level e.sub.1 is lower than e.sub.2 and occurs during the remaining portion of the recording signal. The third level is the smallest (i.e.
