Abstract: Control arrangements for the induction system of an internal combustion engine having a control valve in the induction passage which is moveable between an opened position wherein the flow into the combustion chamber is unrestricted and in a first direction and in closed position wherein the flow into the combustion chamber is restricted to accelerate the velocity of the charge entering the combustion chamber and change its direction from the first direction. Optimum positions are set for the control valve in response to engine speed and engine load but the control valve is held in a closed position when the engine speed is below a predetermined speed and regardless of the load and is also held in an opened position when the engine speed is above a second predetermined speed and regardless of load. Various routines are shown for positioning the control valve to accommodate catalytic convertor warmup, sudden acceleration or deceleration conditions and other transient conditions.

Abstract: An in-line screw type injection molding machine having a screw in a heating cylinder. The screw is driven and rotated by a motor to charge a feedstock resin into the cylinder, the screw simultaneously undergoing retracting movement to allow the molten resin to be stored in the cylinder, and is driven and advanced to inject the molten resin.

Abstract: Disclosed is a shutter-type clamping device which is equipped with: a stationary platen; a movable platen; a base plate; a clamping piston which is lodged in a cylinder provided on the base plate and which has a hollow section; a protrusion provided on the movable platen and having configuration which allows it to enter the hollow section of the piston; and a shutter which allows or hinders the entry of the protrusion into the hollow section; the shutter being attached to the piston and arranged in such a manner as to be capable of moving forwards and backwards and incapable of rotating with respect to a member on the side of the base plate.
