Abstract: A producing apparatus (1) of fine particles includes two pipes constructed by an outer pipe (11) and an inner pipe (21) arranged in a concentric shape. The tip (21a) of the inner pipe (21) is spaced from the tip (11b) of the outer pipe (11) by a comparatively long distance. Fluid II is flowed toward the tip (21a) of the inner pipe (21) within the inner pipe (21). Fluid I is flowed toward the tip of the outer pipe (11) as a continuous phase within the outer pipe (11). The flow velocities of the fluid I and the fluid II within the outer pipe (11) and the inner pipe (21) are set to appropriate values by controlling the operations of respective pumps (14, 24) by commands from a controller (31). Thus, the fluid II exhausted from the tip (21a) of the inner pipe (21) becomes a droplet (3) having a in approximately spherical shape surrounded by the fluid I within the outer pipe (11) and having a predetermined desirable diameter.

Abstract: An equipment and method for charging a secondary battery are provided to quickly and surely charge a secondary battery (secondary batteries) while preventing the secondary battery (batteries) from overcharging or insufficient charging. Special charging voltage Es is applied to a secondary battery for a predetermined time, and then the applied voltage is switched to equilibrium voltage Eeq for establishing equilibrium cell potential of the secondary battery in its fully charged condition, wherein the special charging value Es is larger than the equilibrium value Eeq. Electric current i is detected while application of the equilibrium voltage Eeq. If the detected electric current i is larger than standard electric current J for finishing charging, the above detection and charging are repeated; otherwise, charge of the secondary battery 1 is halted.

Abstract: The steering apparatus in which at least part of the transmission lines (L1, L3) which transmit the control quantity of steering from the steering wheel (20, 120, 220) to the rudder (30, 130, 230) is constituted from a steering cable such as wire so as to steer the rudder by transmitting the control quantity of operating the steering wheel to the rudder through reciprocal motion of the transmission line. The assisting force supplying means (70, 170, 270) is additionally installed and the intermediate linkage rod (60, 160, 260) is installed to interpose in the transmission line, with the transmission line (L2) for transmitting the assisting force supplied from the assisting force supplying means being connected to said intermediate linkage rod in addition to the transmission lines described above, so that the intermediate linkage rod is moved back and forth by the sum of the manual force from said steering wheel and the assisting force from the assisting force supplying means, thereby to steer the rudder.

Abstract: A helm pump (10) rotated either in forward or reverse direction by operating a steering wheel (13) and discharges a liquid of a quantity proportional to the rotating angle, and a double action cylinder moves a rudder (27) and is provided on rudder (27) side of the ship, helm pump (10) and the double action cylinder being connected with the hydraulic circuit of fully closed construction, to move the rudder (27) by an amount corresponding to the amount of liquid discharged from the helm pump (10). A second pump generates discharging pressure in the same direction as the discharging direction from helm pump (10) against resistive pressure generated by the rotation of helm pump (10) due to the operation of steering wheel (13) is installed in series in part of the fully closed hydraulic circuit, so the steering resistance of steering wheel (13) is automatically reduced by the action of the second pump.
