Title: Exhaust gas reflux system of internal combustion engine
Inventor: TSUTSUMOTO NAOYA
IPC: F02M25/07
Filed: 1995-01-17
Abstract: PURPOSE: To check any pressure drop in a pressure supply source for control pressure of an exhaust gas recirculation system. CONSTITUTION: A duty control valve is installed in an EGR(exhaust gas recirculation) quantity controlling vacuum passage 6 connecting an exhaust gas recirculation(EGR) quantity control valve 5 and a vacuum pump, and a passage 6B is connected to this vacuum passage 6 lying between the duty control valve and the EGR quantity control valve 5. This passage 6B is connected to a passage 11 to be interconnected to an intake throttle valve 9 via both first and second solenoid valves 12 and 13. In addition, a driving duty ratio of the duty control valve is controlled and an opening of the EGR quantity control valve 5 is also controlled, while an opening of the intake throttle valve 9 is also controlled at the same time by a combination of opening and closing both these first and second solenoid valves 12 and 13.  In this connection, under the specified conditions, since this exhaust gas recirculation system is so constituted that the atmosphere is led into the EGR quantity controlling vacuum passage 6 from only the first solenoid valve 12, an inducing quantity of the atmosphere into the vacuum pump is reducible and, what is more, any nonconformity attending on a drop in vacuum suction pressure is restrainable.

Title: Detecting method for corroded spot of steel material in concrete
Inventor: HARA YOSHITO
IPC: G01N27/02
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To nondestructively evaluate the corrosion state of steel material in a concrete structure by bringing two or more steel material corrosion detecting ends equipped with each electrode into contact with the surface of the concrete structure, and supplying an AC. current to the detecting end for measuring the polarization resistance of the steel material in the concrete or concrete electric resistance rate. SOLUTION: Measurement is carried out by an AC impedance method which brings at least two steel material corrosion detecting ends equipped with an electrode into contact with the surface of concrete 1 near a steel material to be measured in the concrete and supplys an AC. current. An AC. voltage is applied mutually to electrodes in a detecting pole. In the case where a low frequency is used, an electric double layer capacity C5 becomes a large value as impedance, and polarized resistance Rp3 and concrete electric resistance Rs4 act as the impedance. Next, in the case where a high frequency is used, the capacity C5 becomes a small value as the impedance, and only the resistance Rs4 acts as the impedance. The result of measurement in the case of two point measurement is obtained by adding the resistance Rp3 and the resistance Rs4 as a series circuit.
