摘要:
A process of forming a solid granular film is disclosed, which comprises dispersing solid granules into a liquid with the aid of a dispersant, removing the dispersant from the resulting dispersion to suspend the solid granules at the vapor-liquid interface, and transferring the solid granules onto a support, whereby high covering power is attained with respect to solid granules.

In a vehicle steering control device, a steering torque estimation unit estimates steering torque of a steering wheel based on driving current of an electric actuator; a torque sensor detects the steering torque of the steering wheel; an electric power assist unit is controlled based on the steering torque detected by the torque sensor; and a comparison unit compares the torque detected by the torque sensor with the steering torque estimated by the steering torque estimation unit. The electric power assist unit is controlled based on the estimated steering torque in place of being controlled based on the torque detected by the torque sensor when the torque sensor is judged to be abnormal, based on a comparison.

摘要:
In the control of an electric power steering apparatus, where so-called lead steering control is performed in which a steering wheel angle signal is output through a lead filter to correct reaction delay of a driver and a vehicle, a delay in control response occurs due to feedback of a road surface reaction force torque. When road surface reaction force torque is fed back to the steering wheel, it is added through a low-pass filter having a time constant equal to a reaction delay time constant of a driver. A sum signal is output through a lead filter to a second motor for controlling a steering shaft.

A low-cost torque detection apparatus is obtained using wheel revolution sensors which are generally provided in a conventional ABS and an engine revolution sensor which is generally provided in a conventional engine fuel jet controller. The apparatus can be used, for example, in a vehicle having a drive source, such as an engine or a motor, for driving wheels which is coupled to the right and left wheels by respective shafts having torsional stiffness for transmitting a drive torque through a differential gear. The apparatus includes a drive source revolution angle detection device for the drive source and wheel revolution angle detection means for the right and left wheels, and calculates torques of shafts such as drive shafts for coupling the differential gear to the wheels using a torque calculator.
摘要:
The present invention is a vehicle body conveying apparatus in which a vehicle body (20) conveyed by a shuttle conveyor (32) is then conveyed in the order of an inclining belt conveyor (1) and a slat conveyor (21). A miniconveyor (26) is disposed between the inclining belt conveyor (1) and the slat conveyor (21) in such a relation that a rear end of the miniconveyor (26) overlaps a delivery side of the inclining belt conveyor (1), and the front end overlaps a receiving side of the slat conveyor (21) so as to ensure smooth transfer of the vehicle body (20) between them. Further, the inclining belt conveyor (1) is inclined by an elevating mechanism (8) to separate the vehicle body (20) from the shuttle conveyor (32).
