Abstract: An air-fuel ratio control system for an internal combustion engine having a fuel injection valve for each cylinder and an electronic air control valve (EACV) for controlling intake air bypassing the engine throttle valve. When the target air-fuel ratio is switched over from a rich value to a lean value, the amounts of fuel injected into the cylinders, for example, #1, #2, #3 and #4 cylinders are controlled so that they are sequentially decreased at predetermined intervals, and the EACV is controlled to be opened stepwise. This causes a decrease in engine torque generated by the switching-over of the target air-fuel ratio to be offset by an increase in engine torque generated by an increase in amount of air drawn, thereby preventing the generation of a torque shock. At this time, the target opening degree of the EACV is corrected based on the magnitude of the interval and the magnitude of a loading of the internal combustion engine, thereby further effectively preventing the generation of the torque shock.

Abstract: Satisfactory molding of a spout in the upper inclined opening edge of a glass container is effected by heating the spout molded portion of the upper opening edge to soften it, premolding the heated softened portion by raising it from the inside of the glass container by the premolding member of a spout premolding device, and finish-molding it by a spout molding device. The spout molding device supports the molding device above a glass container setting position for vertical and horizontal movements, and outwardly substantially horizontally moves this molding member, which is put in the glass container, so as to outwardly push and deform the upper opening edge of the glass container in such a manner as to mold a spout. The path of movement of the molding member is controlled by a fixed cam to finish the spout into a desired shape.

Abstract: A separate type dressing consisting of an oil phase and an aqueous phase separately contained, in which the oil phase consists of oils and fats containing a purified fish oil which is substantially free of fish smell components and precursors thereof, and the aqueous phase consists of vinegar containing one or more additives selected from the group including citrus flavor, soy sauce and miso.

Abstract: A pair of metallic thin films are attached to opposite surfaces of a heat resistive thin film, and the heat flux through the heat resistive thin film is determined by measuring the temperature gradient therein while using the metallic thin films as resistance thermometer elements.
