  • Lockup clutch released then re-engaged during deceleration control method
    Patent number: 5562571
    Abstract: A method is provided for the control of the state of engagement of a damper clutch arranged in association with a vehicle engine, which has a fuel cut mechanism for suspending a supply of fuel during a decelerated operation, to permit connection between an input member and an output member in a torque converter arranged on an output side of the engine. Upon detection of a decelerated operation of the engine, the damper clutch is controlled to bring the input member and output member into a desired state of engagement. Here, the damper clutch is first released for a predetermined time and is then moved to an engaged side. Next, the damper clutch is feedback-controlled into a desired slip state so that the input member and the output member are allowed to rotate with a desired difference in revolution speed therebetween. A system for practicing the method is also described.

  • Control method of vehicle engine arranged in association with fluid coupling having clutch
    Patent number: 5498217
    Abstract: A control method is provided for an engine for a vehicle. The engine is arranged in association with a fluid coupling having a clutch. According to the control method, the state of engagement of the clutch is first detected. In the next step, it is determined whether or not the vehicle is in a predetermined decelerated operation state. When the clutch has been detected to be in a predetermined state of engagement in the clutch engagement state detection step and in addition, the vehicle has been determined to be in the predetermined decelerated operation state in the decelerated operation state determination step, an output of the engine is increased in the subsequent step.

  • Floating-refuse-collecting boat
    Patent number: 4128068
    Abstract: A floating-refuse-collecting boat of a twin-hulled construction includes a floating-refuse collector located in the water channel formed between the hulls. A plurality of main water-jet units are installed on the bows of the hulls for directing jets of water rearwardly through the water channel for guiding and forcing the refuse afloat in the vicinity of the entrance into the channel and toward the collector. In addition, a plurality of auxiliary water-jet units are mounted on the hulls rearwardly of the main water-jet units and in front of the collector to provide jets of water which prevents refuse from flowing out of the collector when the boat moves astern.
