Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To stabilize the ground, by adding a soil-stabilizing material while agitating the ground and mixing them, after coarse aggregate or a shearing- reinforcing material have been mixed with the soft ground to increase the strength. SOLUTION: After excavation holes 2 have been formed in a soft ground A down to a specified stabilizing depth by an auger 1 as a boring device, coarse aggregate 3 like aggregate, generated materials, and recycling aggregate are charged in the excavation holes 2. In this time, shearing-reinforcing materials like a carbon fiber or aramid fiber are used instead of the coarse aggregate 3 when required or the shearing-reinforcing materials are mixed with the coarse aggregate 3.

Title: Programmable controller
Inventor: NITTA ATSUSHI
IPC: G05B19/05
Filed: 1994-12-20
Abstract: PURPOSE: To perform the switching between the external input and the external output of a PC (programmable controller) by providing a means which drives a photocoupler to perform the reversible switching between the input and the output by means of a signal received from a control part or an external signal. CONSTITUTION: The circuits of an input/output switching unit 9 are integrated due to a fact that both an input circuit and a transistor output circuit apply the photocouplers 13. When the unit 9 is used as an output unit, the photocoupler 13 is driven by the current supplied from an output port 12. Then the photocoupler 13 is driven by the current supplied from an external input/output terminal 2 when the unit 9 is used as an input unit. Thus the output and the input can send the ON/OFF information to the terminal 2 and an input port 17 respectively. As a result, the input/output switching is attained by inverting the fitting direction of the unit 9 between both cases where the unit 9 is used as the input and output units respectively.
