Abstract: At a torque converter characteristic assuming unit, during non gear shift, gear ratio and an input shaft torque are assumed and also during gear shift, accessory torque is assumed. So as to correct the accessory torque a deviation between pump torque and engine torque is learned and this value is given to the accessory torque, thereby the input shaft torque can be executed and assumed. A drive shaft torque is obtained from a drive shaft torque calculating unit, a control period of the drive shaft torque is determined, a reference drive shaft torque is determined during torque control period from a reference drive shaft torque setting unit. A deviation between the reference drive shaft torque and the drive shaft torque is obtained from a torque deviation executing unit. An engine controlling unit varies the engine torque by controlling an ignition period so as to decrease substantially zero the deviation.

Abstract: A volumetric measurement apparatus is provided which measures the volume of a liquid material stored within a container. The volumetric measurement apparatus includes a reference enclosure having disposed therein a single pressure sensor. The pressure sensor has a pressure sensitive element exposed to both internal spaces of the reference enclosure and the container to detect a pressure difference between the container and the reference enclosure. A sensor shielding member is arranged in the reference enclosure to selectively shield the pressure sensitive element from the internal space of the reference enclosure to detect only a pressure within the container. The volumetric measurement is made based on the pressure difference between the container and the reference enclosure and the pressure in the container.

Abstract: A printer including at least two tractor unit mounting sections upstream of the print position in the sheet feed direction, and at least one tractor unit can be mounted on either of these tractor unit mounting sections. The sheet feeding direction can thus be selected freely in accordance with the web replacement frequency or the printer installation location merely by changing the mounting position of the tractor unit. If the number of tractor units is increased, a plurality of webs can be set up simultaneously and used selectively.

Abstract: A catalyst for gas/liquid reactions, characterized by having a sheet or film-form water-repellent porous carrier having gas permeability and liquid impermeability and a catalytically active component supported on at least one surface of said carrier.
