Abstract: <P>PROBLEM TO BE SOLVED: To hold down the stirring-up of dust in the case of crushing objects to be crushed.  <P>SOLUTION: In the crusher, a motor 30 is coupled to one side of a spindle 22, an upper plate 34 and a rotor 36 are fixed to the other end of the spindle 22. A plurality of grinders 38 are placed rotatably between the plate 34 and the rotor 36, through-holes 42 are formed in the plate 34, and through-holes 50 are formed in the rotor 36. In the rotational movement of the rotor 36 and the upper plate 34 which is caused by rotation of the motor 30, waste industrial-products 14 dropped from a dropping port 16 are crushed by collision with the upper plate 34, the rotor 36, and the grinders 38. Debris resulting from the crushing is discharged through a choke part 48 from a discharge port 18 by rotation of a discharge plate 40. Dust generated in a vessel 12 is discharged together with a down-flow of a gas generated in the center of the vessel 12 through the through-holes 42, 50 from the discharge port 18. Thus, dust is discharged in a reduced time.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a data processor which minimizes the scale of a sequential processing circuit for realizing sequential processing including two-dimensional propagation processing.  <P>SOLUTION: The two-dimensional propagation processing included in the sequential processing is decomposed in two processing, i.e., vertical propagation processing and horizontal propagation processing equivalent to the two-dimensional propagation processing. The vertical propagation processing is processed using a one-dimensional SIMD type processor 41, and the horizontal propagation processing is processed using the sequential processing circuit 81. The bit number of propagated input data is thereby reduced for the sequential processing circuit 81 for realizing the sequential processing including the two-dimensional propagation processing. As a result, a memory for table conversion is made small in comparison with conventional ones, and the scale of the sequential processing circuit 81 is made small.  <P>COPYRIGHT: (C)2004,JPO
