Title: Method and apparatus for dredging work
Inventor: ARAOKA TOSHINOBU
IPC: E02F3/88
Filed: 1982-03-09
Abstract: PURPOSE:To attain stable dredging work all the time by injecting water above deposited soil and sand from an annular waterway between an underwater device and a box into the surrounding of a suction port by means of the suction force of the underwater device when burying the suction port. CONSTITUTION:An underwater device 1, having a lower end near its lower suction port 2 and a box 5 covering the device 1 and having an opening in water above an imaginary deposit level on its upper end, is settled on the bottom under water and dredging work is started. In the course of the dredging work, when the suction port 2 of the underwater device 1 is buried by the falling of  surrounding soil and sand, water above the burying soil and sand is injected  from an annular waterway F between the device 1 and the box 5 into the surrounding of the suction port 2 by means of the suction force of the underwater  device 1. Thus, the fluidity of the soil and sand is improved and stable dredging  work can thus be attained even when the suction port 2 is buried.

Abstract: PURPOSE:To provide the information converter efficiently reducing the amount of processing of the format conversion of the information in performing the communication between dissimilar types to a level of practical use. CONSTITUTION:A semi-decoding means 110 reads code strings read out from a reading means 107 and decodes them to the coefficient matrix in the conversion area.

A re-encoding means 114 rearranges coefficient matrix to the one-dimensional coefficient string after the prescribed quantization of the coefficient matrix. Further, the code string performing the prescribed code allocation is generated. A decoding means 116 rearranges the code strings to the two-dimensional coefficient matrix after the prescribed decoding and the coefficient matrix obtained by performing the next prescribed inverse quantization is converted into the inverse eighth order two-dimensional discrete cosine. Thus, the digital picture data in the space area is generated in succession.
