Abstract: PROBLEM TO BE SOLVED: To reduce the number of events that occur without changing the logic of a circuit and to accelerate logical circuit verification by converting circuit connection information of an extracted asynchronous circuit into circuit connection information of a synchronous circuit, based on circuit conversion information that has been read from a circuit information library. SOLUTION: First, a synchronous circuit extracting part 2 outputs a synchronous circuit and an asynchronous circuit which are divided by a program 1 of HDL description to a logical gate expanding part 3. The part 3 decides whether or not the asynchronous circuit is registered on a circuit information library 4, in order to convert the divided asynchronous circuit into a synchronous circuit. When it has been registered, the asynchronous circuit is replaced by a synchronous circuit that is logically equivalent. When a desired delay value stays in a verifying circuit, the synchronous circuit that is inputted from the part 2 and the replaced synchronous circuit are outputted, and a cycle base simulation/static timing verifying part 11 performs verification.

Abstract: PURPOSE:To inject a grout into a wide area of ground by a method in which a fixed pressure of air is injected into the ground to be improved to form an air path in the ground, and a liquid or powder soil stabilizer (or improver) is injected into the air path. CONSTITUTION:A pit is drilled in the ground 20 by a rotary boring machine 22, and an air pipe 24 is injected into the pit 26. A hose 30 is connected to the air pipe 24, and a fixed pressure of air is sent to the jet nozzle 28 of air pipe 24.
