Abstract: As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the "Lead-On-Chip" or "Chip-On-Lead" structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

Abstract: A fuel carbureted in a float chamber of a carburetor is prevented from entering through an air vent path into an air intake path during low velocity running of a vehicle. An outer vent path and an inner vent path are provided on the upstream side of an air vent path which communicates with a float chamber of a carburetor of an engine for a vehicle. The paths are alternatively selected by a solenoid valve. An opening of the inner vent path is opened in the intake duct, and an opening of the outer vent path is opened at a position sufficiently spaced away from the front face air intake. During low velocity running, the solenoid valve is selectively operated so that the outer vent path is in communication with the carburetor. During high velocity running, however, the inner vent path is in communication with the carburetor.
