Title: Flow straightening device
Inventor: KUMAGAI MINORU
IPC: G01F15/00
Filed: 1993-05-20
Abstract: PURPOSE:To effectively straighten the turbulent flow due to velocity distribution change from three-dimension to two-dimension so as to improve the flow metering accuracy by providing a fluid supplying adapter in which one end shape is circular and the other end shape is rectangular and whose shape changes gradually between them. CONSTITUTION:A fluid adapter 5 is provided between a fluid supplying flow passage 1 having a circular section in which a fluid velocity distribution becomes three-dimensional and a flowing-in space 3 having a flat and rectangular section in which a fluid velocity distribution becomes two-dimensional. The adapter 5 has an end part on the passage 1 side that is circular same as the passage 1 and an end part on the space 3 that is flat and rectangular same as the space 3. Further, its shape gradually changes from the circular end part to the rectangular end part and the flow passage construction has no incontinuous part. Thus a velocity distribution three-dimensional fluid flowing through the passage 1 smoothly changes into a gradual two-dimensional flow in the adapter 5 with an aid of the passage shape, and it flows out in a straightened state without generating an irregular turbulence or vortex. As a result, the flow metering accuracy can be improved to the great extent.

Filed: 1994-05-31
Abstract: PURPOSE:To fast read and write the information by defining the specific data as the address input of a buffer and converting the continuous address designation data into the addresses of the memory blocks which are related with each other by a chain pointer. CONSTITUTION:An address conversion circuit 8 placed between a memory 2 and a transmission disassembly/assembly circuit 3 and a reception assembly circuit 4 stores the relative block number data given from a head memory block in the order of connection.
