Abstract: In order to provide a dispersion method and a dispersion apparatus capable of mixing a material to be processed and a dispersion medium having no affinity with each other using a single apparatus without using a dispersant, there are provided a quantitative supply mechanism quantitatively supplying a material to be processed, a suction stirring mechanism primarily including a suction stirring pump in which the material to be processed and a dispersion medium are subjected to negative pressure suction by a negative pressure suction force generated by rotation of a rotating blade and the suctioned material to be processed and the dispersion medium are stirred and mixed by the rotating blade and are allowed to pass through a throttle passage to cause cavitation, and a plasma generating mechanism generating a plasma in bubbles formed due to cavitation in a mixed liquid of the material to be processed and the dispersion medium.

Abstract: An apparatus for retrieving the desired information from files provided with a shift register (294) having a predetermined number of stages for receiving and transferring the data read out of files, a key register (292) having a predetermined number of stages for registering the retrieval key, a comparator (296) for comparing each data in the key register with each dater in the corresponding shift register, and a logical operation circuit (297) which generates and outputs a match signal relating to the coincidence or mismatch of the retrieval key in the key register with a data array in the corresponding shift register.

Abstract: A cursor generating apparatus applicable to computer graphics is disclosed. The cursor generating apparatus comprises registers (47, 49) for receiving and holding information indicative of start and end points of a vertical cursor; a counter (57) for counting block numbers now being scanned on the basis of scanning timing related signals, when a scanning line is divided into plural blocks each including a predetermined number of pixels on the display screen; comparators (53, 55) for comparing the block number outputted from this counter (57) with a block number belonging to start and end points included in the information held in the registers (47, 49) and generating start and end point timing signals; and a circuit (63) for generating a width timing signal on the basis of the start and end point timing signals. These start and end point timing signals, the width timing signal, and some information indicative of the start and end points are applied to the vertical cursor data memory (65) as address data.
