    Abstract: A throttle valve control system for an internal combustion engine installed in a vehicle. A throttle valve opening sensor detects an actual opening of a throttle valve, and an ECU calculates a desired opening of the throttle valve according to the rotational speed of the engine and the required torque of the engine, which is calculated according to operating conditions of the engine and operating conditions of the vehicle, and electrically controls the throttle valve such that the detected actual opening of the throttle valve becomes equal to the desired opening of the throttle valve. An intake pressure sensor detects actual intake pressure within the intake passage, and desired intake pressure within the intake passage is calculated according to the rotational speed of the engine and the required torque of the engine. The desired intake pressure is compared with the detected actual intake pressure, and the desired opening of the throttle valve is corrected based on results of the comparison.

    Abstract: The present invention relates to a retrieval space determination system for three-dimensionally shaped parts in a computer aided design (CAD) system. An input unit inputs coordinates of two points defining one side of a retrieval space displayed on a display screen and inputs the depth of the retrieval spaced based on that side. A file stores three-dimensional shape data. A circumscribing sphere creating unit reads a selected three-dimensionally shaped part from the file storing the three-dimensional shape data and creates a circumscribing sphere for the selected three-dimensional shape part in accordance with the coordinate data of the part. The coordinate conversion unit converts center coordinates of the circumscribing sphere, created by the circumscribing sphere creating unit, into coordinates of the retrieval space input from the input unit. An in/out decision units compares the center coordinates of the circumscribing sphere converted into coordinates of the retrieval space, the radius of the circumscribing sphere, and the coordinates of the sides of the retrieval space and, based on this data, determines whether the circumscribing sphere is completely included within the retrieval space or is only partially included within the retrieval space.

    Abstract: Described herein is a method for controlling the bypass air flow of internal combustion engine, which prevents the air-fuel ratio from becoming over rich temporarily in the initial stage of deceleration of the engine by driving a control valve to open a throttle by-pass passage on deceleration of the engine to supply auxiliary air thereto and which includes: detecting the open angle of the throttle valve; setting a valve opening rate according to the throttle open angle; setting an upper limit on the valve opening rate when it is greater than an upper limit value determined in relation with the engine speed; driving the control valve according to the valve opening rate; and on deceleration of the engine, gradually reducing a valve opening rate set in an operation prior to the deceleration.

    Abstract: A controller stops a fuel injection when a vehicle is in a specified decelerate condition where the vehicle likely stops and an automatic stop requirement is generated. An input shaft and an output shaft of a shift transmission mechanism are directly connected with each other through a direct connector so that a driving power is transmitted from an engine to a driving shaft through a power transmitter which permits a sliding between an input shaft and an output shaft thereof. When a restart requirement is generated before the vehicle is completely stopped, the engine is restarted under a condition where the input shaft and the output shaft of the shift transmission mechanism are connected with each other by a direct connector. When the restart requirement is not generated before the vehicle is completely stopped, the input shaft and the output shaft are disconnected when the vehicle is completely stopped.
