Coarsely crushed toner particles comprising at least a binder resin and a colorant are effectively pulverized by a mechanical pulverizer including a generally cylindrical rotor rotating about an axis and a stator surrounding the rotor with a minute gap from the rotor. The resin composition has good moldability, workability, mechanical properties, heat resistance and transparency, and may be worked into moldings, films and fibers for practical use. If a terminal user selects a specific text field, the selected text field is enlarged or a text field input window is generated. Between the hydrogen storage tank and the anode chamber, a turbine is provided, which supplies at least a portion of the power required for driving the pumping device. With this, a level shifter of the present stage operates only for a period minimum for outputting the shift output from the present block, so that the power consumption is reduced, Furthermore, it is possible to cause the outputs SL1 through SLn not to overlap each other. The new cross-linked electrolytes are insoluble in organic solvent and show much better mechanical strength.
