Abstract: An air-fuel ratio control system for an internal combustion engine includes an air-fuel ratio sensor arranged in the exhaust system of the engine, for detecting the air-fuel ratio of exhaust gases from the engine. An ECU calculates an adaptive control amount, based on an output from the air-fuel ratio sensor, by using an adaptive controller having an adaptive parameter-adjusting mechanism, such that the air-fuel ratio of a mixture supplied to the engine is converged to a desired air-fuel ratio, and controls the air-fuel ratio of the mixture in a feedback manner, according to the adaptive control amount. When a particular engine operating condition in which the adaptive controller can become unstable in operation is detected, the adaptive parameters are initialized according to the adaptive control amount.

Abstract: In an engine exhaust recirculation device, a target exhaust recirculation rate is determined based on an engine running state. The required flowpath cross-sectional area of the exhaust recirculation passage to obtain a target exhaust recirculation rate is calculated from the target exhaust recirculation rate, fresh air amount, an intake pressure and an exhaust pressure. By determining a target opening of the exhaust recirculation valve from the required flowpath cross-sectional area of the exhaust recirculation passage and a predetermined coefficient specifying a relation between the required flowpath cross-sectional area and the opening area of the exhaust recirculation valve, the precision of controlling the exhaust recirculation amount is enhanced.

Abstract: A foldable archery bow has a center section and two flexible arms extending in substantially opposite directions, describing a bow plane, and a separation interface disposed in the center section and positioned to allow the bow to be separated into to separate sections. At least one latching connector is attached to a first point on one of the flexible arms, and is adapted, when the flexible arm to which it is attached is substantially flexed, to latch at a second point on the same side of the separation interface as the first point. By drawing the bow, which flexes the flexible arms, and latching the latching connector, all tension is released from the bow string or strings, and all forces thereby removed from the separation interface. The separation interface, normally fastened in a closed position, may then be unfastened and separated, allowing the bow to divide into the two separate sections forming a smaller package than in the assembled aspect.

Abstract: An improved method and apparatus for opening and closing a high performance shape memory alloy (SMA) fuel injector that minimizes performance variations due to changes in ambient temperature. When opening the injector to commence fuel injection, a relatively high voltage is applied to an SMA element of the injector to quickly heat the element to its high temperature state, quickly opening the valve. The current level is monitored as a measure of the element resistivity, and when the determined resistivity indicates that the high temperature state transition is complete, the voltage is reduced to a hold value, sufficient to continue resistivity measurement. When the determined resistivity indicates that the element is beginning to transition back to the ambient temperature state, the high voltage is re-applied to begin a new control cycle. To close the injector, the electric heating is discontinued, and fuel circulating through the injector cools the element to its ambient temperature state.

Abstract: The present invention relates to an excess flow valve system having a sliding poppet within a chamber with an orifice at one end, wherein the closing flow rate settings can be adjusted. Precise adjustments can be made externally by turning a threaded member extending through the valve, which causes a retainer, threadably located on the member, to move laterally within the chamber. This movement causes an angled surface on the retainer to engage and slide in relation to a similarly angled surface on the poppet. As the poppet is urged toward the retainer by a coiled spring, the poppet is moved longitudinally within the chamber, either toward or away from the orifice. Turning the threaded member enables the maximum travel distance of the poppet, and therefore, the threshold flow rate of the valve, to be precisely set.

Abstract: The liquid transfer system includes a liquid supply tank and at least two pressurizable liquid holding vessels. The liquid holding vessels are placed beneath the supply tank, and a liquid supply line connects the supply tank to each vessel.

Each vessel is alternately filled and pressurized to dispense liquid from the vessel, such that one vessel is being filled while the other is dispensing liquid, and a constant controllable liquid output flow is achieved. A preferred embodiment includes a liquid recycling line to recycle or constantly move the liquid within the system to achieve thorough mixing, and an in-line filter to improve liquid purity.

Abstract: A thermal safety device is disclosed which, in the area of the closing element, has an uninterrupted circular cross section. Furthermore, the axial guiding of the closing element during the closing stroke is ensured. In the axial continuation of a seat located within the casing there is a guide pin. A closing spring is aligned on this guide pin, and, when taut, the spring is situated as far as possible inside a blind hole, with a throat acting as a control edge, inside the closing element. Under the influence of the closing spring, a ram forming a part of a detecting element, keeps the control edge adjacent to a clip-stop edge when the safety device is in the open position. Once the thermal solder element melts away, however, the resulting change in position of the ram allows the control edge to move away from the click-stop edge, so that the closing element, under the influence of the closing spring, moves into a closed position.

Abstract: A membrane-type inflation nozzle applicable to an inflatable envelope. A release sheet is disposed between two nozzle membranes at an opening of the nozzle. An adhesive material is disposed between inner membrane walls of the opening of the nozzle. One end of the release sheet is positioned between the adhesive material and the other membrane wall.

Therefore, an internal pressure of the envelope makes the nozzle self-close. In addition, the adhesive material at the nozzle opening is able to adhere corresponding inner membrane walls to each other so as to achieve a more tightly air-sealing effect.

Abstract: A method and system for automatically verifying the function of pressure and vacuum relief valves for low-pressure storage vessels and tanks, which can be remotely operator actuated to insure venting when emergencies occur, allows for on-line verification of the relief valve functionality and proper operation. The system periodically checks the set pressure of the valve by attempting to lift its pallet and measures the deviation from a set point. It also indicates unplanned occurrence of valve lifting, as a result of unforeseen upset in storage vessel pressure. This apparatus is electrically operated and controlled and relies on electromagnetic means for tractive or pull-force, as well as for detecting valve lifting.

Abstract: An inner diameter of a filler tube is formed smaller than that of a filler neck of a tank main body. Hence, a clearance is thus difficult to be created between inner peripheral surface of the filler tube and the fuel stream which flows through the filler tube upon supply of fuel, and also leakage of vapor fuel from a fuel filler port can be avoided. In addition, a cylindrical insert whose inner diameter is formed to be substantially equal to its of the filler tube is provided in a neck portion of the filler hose. Accordingly, there exists no portion where the inner diameter is largely changed in the filler neck portion, whereby generation of turbulent flow of the supplied fuel and reduction in a flow rate can be suppressed to their maximum and thus fuel supply performance can be enhanced.
