Abstract: Disclosed is a user terminal for wireless communication with a remote access point. The user terminal may include a mapping module adapted to map one or more input data bits to an uplink symbol, a delay module adapted to apply a delay to the uplink symbol, a transmit module adapted to modulate the delayed symbol into a frequency channel, and an antenna being adapted to transmit the modulated symbol to the access point. The delay can be chosen such that the transmitted symbol arrives at the access point simultaneously with a further symbol modulated into the frequency channel and transmitted by a further user terminal.

Abstract: Disclosed is controlling a vibration of a vibration generating device configured to reciprocatively vibrate an operating body movably supported in a first direction and a second direction which are opposite to each other, a driving signal being transmitting to a first interval and a second interval in which vibration frequencies of acceleration during movement of the operating body are different from each other, the first interval being an initial motion interval when the operating body moves toward the first direction, the second interval being an initial motion interval when the operating body moves toward the second direction. The vibration frequency of the second interval is smaller than the vibration frequency of the first interval which is equal to or smaller than 250 Hz, and the vibration frequency of the second interval is greater than the vibration frequency of the first interval which is equal to or greater than 250 Hz.

Abstract: An object is to prevent an engine from entering an unstable combustion state such as misfire upon recovery, by halting or reducing gas fuel for a cylinder in which knocking is occurring, and then increasing the gas fuel again to appropriately perform a recovery control upon recovery to the optimum operation. A combustion control device for a gas engine includes: a knocking determination unit 49 configured to determine occurrence of knocking of each of cylinders; a knocking reduction unit 55 configured to halt or reduce supply of gas fuel to a cylinder in which the knocking is occurring and reduce supply of the gas fuel to other cylinders in which the knocking is not occurring; a first recovery unit 57 configured to recover a state where the gas fuel is halted or reduced in the cylinder in which the knocking is occurring; and a second recovery unit 59 configured to recover a state where the gas fuel is reduced in the other cylinders which are not the cylinder in which the knocking is occurring.

Abstract: In a gas engine 1 that uses a gas having a lower specific gravity than air and has a pre-mixing device before a turbocharger, a pre-mixed gas mixture compressed by a turbocharger 3 is cooled by an intercooler 4 located downstream of the turbocharger 3 in the intake system. Condensed water produced as the gas is cooled and the pre-mixed gas mixture discharged with the condensed water are separated into condensed water, air, and fuel gas in a vapor-liquid separator 7. The fuel gas is returned to the intake system upstream of the turbocharger 3, while the condensed water is discharged to atmosphere.
