Abstract: A inject gas control device that performs, for example, control reflecting variation in vessel velocity over time without adversely affecting the main engine is realized. That is, it is prevented that gas is drawn too much and thereby a gas supply or charged air rate becomes insufficient, efficiency of the main engine is decreased and exhaust gas is deteriorated, and analogous events occur because the gas supply or charged air rate is too much instead. There are provided a main engine 4010 acquiring propelling power for a vessel 1, and a turbocharger 4011 that is driven by exhaust gas from the main engine 4010 and blows pressurized gas to the main engine 4010. A part of the pressurized gas and/or exhaust gas is drawn from between the turbocharger 4011 and the main engine 4010 (5023, 5024 and 5025).

Abstract: A vehicle drive force control apparatus is provided that can stabilize the output of the electric motor even if the engine rotational speed experiences an acute change. The output of an engine is delivered to the left and right front wheels through a transmission and also to an electric generator. The output voltage of the electric generator is supplied to an electric motor and the output of the electric motor drives the left and right rear wheels. The drive force control device predicts if the rotational speed of the engine will decrease or increase acutely based on the upshifting and downshifting of the transmission and adjusts the field current of the electric generator up or down before the acute change in the engine rotational speed occurs.

Abstract: A sheet-conveying device includes a sheet conveying path along which a sheet is conveyed, a conveying roller, an inclined roller, an inclined-roller-supporting member that supports the inclined roller such that the inclined roller can rotate around a rotational axis that is inclined with respect to a rotational axis of the conveying roller, and a sheet contact member having a contact surface with which an edge portion of the sheet comes into contact. The inclined-roller-supporting member moves between a position where the inclined roller comes into pressure contact with the conveying roller and a position where the inclined roller is separated from the conveying roller. The sheet contact member moves between a position where the edge portion of the sheet can come into contact with the contact surface and a position where the contact surface cannot restrict the position of the edge portion of the sheet.

Abstract: A generated power control system in which the magnetic field of a generator is controlled based on a target generated power so as to perform the appropriate generation control. Preferably, the generated power control system is used in a hybrid vehicle having a generator configured to be driven by an internal combustion engine that drives a first wheel and an AC motor that drives a second wheel not driven by the internal combustion engine with an inverter arranged to supply generated power from the generator to the AC motor. Basically, the generated power control basically calculates an AC motor power requirement of the AC motor and a target generated power to be generated by the generator based on the AC motor power requirement, and then controls the generated power generated by the generator by controlling a magnetic field of the generator based on the target generated power calculated.
