    摘要: An air-fuel ratio control system for an internal combustion engine including a carburetor having a main fuel system, a slow fuel system, a main bleed air passage leading to the main fuel system a main bleed air control passage leading to the main fuel system, a slow bleed air passage leading to the slow fuel system, and a slow bleed air control passage leading to the slow fuel system, and a valve for controlling the amount of bleed air supplied through the main and slow bleed air control passages. An electronic control unit controls the operation of the valve and is capable of carrying out a feed-back control for controlling the operation of the valve on the basis of a signal from the oxygen sensor so as to bring the air-fuel ratio into a theoretical value, and which determines a control value in such a manner that a feed-back control value is learned and stored to provide a learned value which is substantially constant with respect to fuel of a constant calorific value, and the stored learned value is reflected to a next control value. Thus, it is possible to perform a prompt and stable control of air-fuel ratio in accordance with a variation in calorific value of fuel and to stably and finely vary the amount of bleed air.

    摘要: A drain pump that maintains pump performance and reduces noise and vibration accompanying water scooping of a rotary impeller includes a large-diameter blade divided into an inner blade and an outer blade. A radius of an impeller scooping up water is the sum of the lengths of the inner and outer blades in a radial direction. The large-diameter blade is divided at a position where the amount of generated air bubbles is large, and the inner and outer blades are alternately disposed. Accordingly, air bubbles are escaped to a downstream side in a rotational direction, so that the intensity of the collision between the blades and air bubbles is decreased reducing noise caused by the burst of air bubbles and vibration caused by a collision load of the flow of a gas-liquid mixture.

    摘要: A method is provided for separating trivalent actinides and rare earth elements in the TRUEX method using a CMPO-TBP mixed solvent. The method of separating trivalent actinides and rare earth elements comprises a trivalent actinide/rare earth extraction step wherein trivalent actinides and rare earth elements are extracted by a solvent from highly acid waste generated by reprocessing of spent nuclear fuel, a nitric acid removal step wherein the nitric acid concentration of the solvent used to extract the trivalent actinides and rare earth elements is reduced, and a separation step wherein the trivalent actinides and rare earth elements contained in the solvent of low nitric acid concentration, are separated from each other.
