An object of the invention is to provide a method of controlling a gate valve that operates the gate valve in a short time while suppressing vibration of the valve body. A method of controlling a gate valve provided on an opening of a chamber, wherein the gate valve includes a valve body that opens and closes so as to close the opening of a chamber, a valve seat provided on the edge of the opening to which the valve body is pressed, and a sealing material for sealing between the valve body and the valve seat. The invented method is characterized in that, in moving the valve body to the open position from the closed position where the valve body is pressed against the valve seat with the sealing material compressed, the valve body is made to stop temporarily for a predetermined time at the position immediately before the compressed sealing material is pulled apart or immediately after pulled apart in the opening movement of the valve body.

A transmission designed to transmit a torque flow from a driving device to a driven device. The transmission includes an actuator including a rotor and a stator. The transmission further includes an output or an input shaft. The rotor is connected non-rotatably to the output shaft or to the input shaft, and the actuator and the driven device are arranged at different ends of the output shaft or the input shaft. The actuator is different from the driving device and the driven device.

A method for operating a hydraulic valve of a hydraulic device of a motor vehicle transmission device, wherein an actuating current of the hydraulic valve is superposed with a modulation alternating current in order to adjust a shaking vibration of the hydraulic valve by a control device, wherein a deviation between an actual pressure resulting from the actuating current and a setpoint pressure determined as a function of the actuating current is determined for the hydraulic device by means of an electronic computing device, and an amplitude and/or a frequency of the modulation alternating current is increased as compared to a starting value equalizing a hysteresis of the actual pressure relative to the setpoint pressure, as a function of a tolerance range being exceeded by the determined deviation.

A method and device for adjusting performance variables of an aircraft. The device which is intended for adjusting performance variables, the performance variables being generated by at least one performance module, includes an auxiliary data input unit for entering into a flight management system correction data intended to be used for adjusting at least one associated performance variable, and a correction unit for carrying out a correction, the correction including adjusting the associated performance variable on the basis of the input correction data.

A vibration-proof fastener post structure includes a body portion having a first end integrally formed with or assembled to a first object; a fastening head portion movably mounted to a second end of the body portion and having a neck portion, which is movably disposed in the body portion for moving in a slideway hole of a second object; and an elastic element movably fitted around the neck portion to push against the body portion. The fastening head portion and the body portion are configured for engaging with and fastening to the slideway hole of the second object. The second object is slidably relative to the neck portion. When the second object is slid to a predetermined position, the fastening head portion and the elastic element, the body portion or the pushing member will engage with the slideway hole of the second object to achieve a vibration-proof fastening effect.
