A specific RAM 150 has a data area corresponding to the address space of the command RAM 120 and records specific bit data based on the count value of the program counter 110. Therefore, the specific bit data is written in a data area corresponding to the address where the command RAM 120 is accessed. By analyzing the address of the bit data, the coverage of firmware can be grasped.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for placing concrete
Inventor: HIGASHIDA TETSUYA
IPC: E04G21/02
Filed: 2002-05-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for placing concrete in which a fine surface, on which there are few cavities and indents by bubbles, is obtained in a concrete secondary product or cast-in-place concrete.  <P>SOLUTION: Kneaded concrete 4 is charged into forms 1, and the inside of concrete is supplied with a water-soluble gas. When the inside of concrete is supplied with the water-soluble gas, a greater part of the gas is discharged naturally because there are a large quantity of gas components. Since air is discharged together and most of the gas components remaining at a fixed ratio are displaced with the water-soluble gas in this case, the gas components dissolve into moisture in concrete. Accordingly, the surface is cleaned and compacted sufficiently, and concrete under the state in which there are few bubbles on the inside-in other words-few cavities can be completed. Carbon dioxide is preferable as the water-soluble gas.  <P>COPYRIGHT: (C)2004,JPO
