Abstract: PURPOSE:To prevent the primary air-to-fuel ratio from becoming excess in a controller for controlling the feedback of the primary air-to-fuel ratio of a carburetor to the secondary air-to-fuel ratio of exhaust gas by enabling to introduce atmosphere air into a slow port of a slow passage when an idle increasing mechanism is operated. CONSTITUTION:A negative pressure control valve 7 closes the suction negative pressure takeup port 5 side of a negative pressure conduit 6 in an ordinary drive state, thereby introducing atmospheric air to a negative pressure control valve 4 and a diaphragm unit 8 side. Accordingly, the valve 4 closes an atmosheric air port 4E, and the diaphragm unit 8 is disengaged from the lever 12A of a throttle valve 12. On the other hand, when a cooler switch 9 is closed by the use of a cooler, the valve 7 is switched by a controller 11 to the atmospheric air port closed side. As a result, negative pressure is transmitted to respective negative pressure chambers 4A, 8A, the throttle valve 12 is opened to an idle increasing opening by the leftward movement of the rod 8D of the unit 8. Further, the atmospheric air port 4E is opened, and the atmospheric air is introduced into a slow port 3.

IPC: H05F3/04
Filed: 1987-06-02
Abstract: PURPOSE:To remove electric charge accurately from a charged traveling body even when it is traveling in a high speed by removing electricity to some extent by means of a high-frequency corona discharge, and at the same time, making the charge uniform, and then removing electric charge through neutralization by means of a d.c. corona discharge which is of opposite polarity to the residual potential. CONSTITUTION:After the electric charge is removed from a charged traveling body 1 by means of a high-frequency corona discharge through high-frequency electricity removers 9, 10, the electric charge is removed from the residual potential through neutralization by means of a d.c. corona discharge which is of opposite polarity to the residual charged polarity, and generated by a d.c. electric charge remover 7. The uneven charge on the surface of the charged traveling body 1 is made uniform by the plus and minus ionized ion generated by the high-frequency corona discharge. Since the action is a high frequency, even when the traveling body is running at a high speed, it is performed accurately. Thereby, if the electric charge is removed through neutralization by generating a d.c. corona discharge which is of opposite polarity to the polarity of the residual potential after it is removed by A high-frequency removal of electricity, the residual potential after the highfrequency removal of electric charge can be removed.
