摘要： Disclosed is an ink droplet expelling apparatus for expelling an ink droplet in response to an electric signal, compising a printing head provided with one or more ink chambers, electro-mechanical transducers disposed on the printing head corresponding to the ink chambers, and a driving signal generating circuit for producing electric signals for driving the electro-mechanical transducers. The elector-mechanical transducers are distorted by three different driving signals to reduce the volumes of the ink chambers to raise the pressure therein to thereby expel an ink droplet out of a nozzle formed at the front end of the head. The three driving signals are applied to the electro-mechanical transducers in a predetermined order, the first one giving the ink a velocity, the second one accelerating the ink to expel it in the form of an ink droplet out of the nozzle, the third one acting to suppress the pressure fluctuation in the ink chambers caused by the first and second driving signals as well as to supplement ink in the ink chambers from an ink tank.

摘要： A liquid droplet projection apparatus is disclosed which comprises a nozzle arranged at a liquid droplet ejection head, a liquid droplet supply tank, and an electro-mechanical transducer section interposed on the head between the nozzle and the tank. The volume of the electro-mechanical converter means changes in volume in response to an electrical signal pulse applied thereto to cause the nozzle to eject liquid droplets in accordance with the electrical signal. When the pattern of the electrical signal applied to the electromechanical transducer section has an interruption period longer than a predetermined width and three or more successive electrical signals following the interruption period, the amplitude and/or width of the second one of the successive electrical signals is enlarged as compared with the amplitude and/or width of the other electrical signals, thus preventing the diameter of the second liquid droplet ejected following the interruption from being reduced.

摘要： A control system and method for a multi cylinder engine that employs a single sensor associated with only one of the combustion chambers for feedback control of that combustion chamber and for controlling the fuel/air ratio of the remaining combustion chambers. The control of the remaining combustion chambers is based upon the value of the feedback control upon the time of shifting between lean and rich mixtures. The reference value is selected, however, after the initial switch between rich and lean so as to permit time for stabilization.

摘要： A marine propulsion engine control system wherein the control includes an arrangement for slowing the speed of the engine by disabling certain cylinders in the event of an abnormal engine running condition. Also, an arrangement is provided for slowing the speed of the engine if a change speed transmission for driving the propulsion shaft by the engine offers more than a predetermined resistance to shifting. The controls are interrelated so that the engine protection control predominates. That is, if the engine is in protection control mode and the operator attempts a shift and more than a predetermined resistance is felt, the shift control routine will not be initiated to effect any additional engine speed reduction. In addition, when the engine speed is reduced, fuel is continued to be supplied by the fuel injectors to avoid backfiring, stalling, and uneven running. When rapid deceleration is called for the spark advance is rapidly retarded but fuel injection amount is gradually decreased.
摘要翻译： 一种船用推进发动机控制系统，其中所述控制装置包括用于通过在发动机运转异常的情况下禁用某些气缸来减慢所述发动机的速度的装置。 此外，如果用于通过发动机驱动推进轴的变速传动提供超过预定的换档阻力，则提供了用于减慢发动机的速度的装置。 控制是相互关联的，因此发动机保护控制占优势。 也就是说，如果发动机处于保护控制模式并且操作者尝试换挡并且感觉到超过预定的阻力，则不启动变速控制程序以实现任何附加的发动机转速降低。 此外，当发动机转速降低时，由燃料喷射器继续供给燃料，以避免后燃，失速和不均匀运转。 当需要快速减速时，火花提前快速延迟，但燃料喷射量逐渐减小。

摘要： Several embodiments of remote controlled helicopters wherein the longitudinal position of the helicopter is controlled by means of a tether wire affixed to the rear of the helicopter. In some embodiments, the connection of the tether wire to the fuselage is such that at least a portion of the torque created on the fuselage by the rotation of the main rotor is absorbed by the tether wire.

The control of the remaining combustion chambers is based upon the value of the feedback control upon the time of shifting between lean and rich mixtures. The reference value is selected, however, after the initial switch between rich and lean so as to permit time for stabilization. Engine protection is accomplished by cylinder diseabling. At that time feed back control is discontinued.
