To provide a process for efficiently producing a fluorine type antifouling composition employing a short chain Rf group, which can be made in the form of an aqueous dispersion containing substantially no volatile organic solvent and has a good soil release property. The device comprises at least one injector forming the second drop above the first drop. Moreover fruit can be consumed crunchy or melting. Similar techniques can also be utilized in a multi-segment digital-to-analog converter in which each segment of the DAC is controlled by a 3-level control signal and the DAC is implement using PMOS devices. The lock mechanism also includes a third locking portion extending radially from the locking ring assembly opposite the first locking portion and circumferentially about the axis of rotation for engaging a second of the two shafts and spaced the second locking portion along the axis of rotation. New video data is generated in the first format by processing the modified video data.
