Abstract: An injection-foaming molding process for manufacturing a formed article by injecting a molten resin containing a foaming agent into a cavity of a mold being retained in an openable state and then expanding the cavity by opening the mold to allow the resin to foam includes: i) a step of discontinuing a cavity of a mold from a resin-reserving section located at front end of a screw immediately after the completion of injection of a molten resin containing an expandable resin into the mold cavity; and ii) a step of keeping the resin-reserving section under pressure at least equal to back pressure for charging during a period from the completion of injection to start of charging the molten resin containing the expandable resin for next shot, decreasing pressure in the resin-reserving section to back pressure for charging, and then starting the charging. According to the process, a molding cycle can be shortened and a lightweight formed article by foaming having high rigidity and good appearance can be obtained.

Abstract: The idle speed control device according to the present invention controls a two-solenoid rotary type idle speed control valve properly even when one of the solenoids fails. When one of the solenoids fails, the device calculates the amount of bypass air from the amount of inlet air and the degree of opening of the throttle valve, and estimates the degree of opening of the idle speed control valve. If the degree of opening of the bypass valve is larger than that of the neutral valve position, the device sets the duty ratio of the control signal for driving the idle speed control valve at 0%, and if the degree of opening of the idle speed control valve is less than that of the neutral valve position, the device sets the duty ratio of the control signal at 100%. By this control, the two-solenoid rotary type idle speed control valve is maintained at neutral valve position without determining the type of the failure of the solenoids precisely.
