Abstract: For an engine that draws a complicated torque trajectory, it has been taken a lot of time to adapt a time constant for calculation of estimated torque. Therefore, an ECU 102 includes a target torque calculation unit 203 that calculates target torque of an engine for which torque-based engine control is performed using estimated torque, and an estimated torque calculation unit 210 that calculates the estimated torque by calculating a primary delay coefficient 304 equivalent to a time constant calculated for each control cycle based on a change in an actual intake air amount with respect to a target intake air amount of air sucked into the engine and performing primary delay processing on the target torque using the primary delay coefficient 304.

Abstract: The present invention provides a method for producing an absorbent sheet containing absorbent resins, hydrophilic fibers, and hydrophobic fibers, comprising: a dehydration step of dehydrating the absorbent resins and the hydrophilic fibers from a state of being in contact with each other and containing water to obtain composite compositions; and a sheet-forming step of forming a sheet of the composite compositions and the hydrophobic fibers by heating while bringing the composite compositions and the hydrophobic fibers into contact with each other.
