    摘要: A cooling system which includes an occluding section for occluding vaporized cooling agent by means of an occluding agent so as to ensure continuous evaporation of cooling agent in the evaporating section. The system includes a high pressure and low pressure recovery sections for recovering the cooling agent from the occlusive agent by applying heat thereto. When a low potential energy is available, the occlusive agent is passed from the occluding section only to the low pressure recovery section, but when a high potential energy is to be used, it is passed through the high and low pressure recovery sections in this order.

    摘要: A hydraulic drive system is provided with a generator 8 for outputting electricity corresponding to a rotation speed of an engine 7, an electric motor 11 drivable responsive to the electricity from the generator 8, hydraulic pumps 12a, 12b drivable by the electric motor 11, truck-body elevating cylinders 6 for pivoting a truck body 5 in an up-and-down direction, and a stroke detector 14 for detecting a stroke of the control apparatus of the truck-body elevating cylinders 6, and is also provided with a controller 19 for performing control of engine rotation speed. The controller 19 includes a motor electric-power computing means 19a for determining electric power for the electric motor 11, which corresponds to the stroke detected by the stroke detector 14, and a discrimination means 19b for discriminating whether or not the electricity from the generator 8 has become greater than the thus-determined electric power for the electric motor 1.

    摘要: In a hydraulic drive device for vertical pivoting movement of a load carrying platform, a first directional control valve has only three switchover positions, including a neutral position relating to operation of stopping and holding a load carrying platform, a switching position relating to operation of lifting the load carrying platform, and a switch over position relating to operation of forced lowering of the load carrying platform. A second directional control valve has only three switchover positions, including a neutral position, a switching position, and a switchover position relating to operation of allowing the load carrying platform to fall by its own weight. The device includes a first on-off valve, a second on-off valve, and a third on-off valve that are proportional control solenoid valves for switching an appropriate one of the first and second directional control valves.

    摘要: A secondary cleaning device has a cleaning brush, collection roller, and controller. The cleaning brush is driven by a drive mechanism and thereby rotates in a state that brush fibers thereof are contacting with a secondary transfer belt to collect toner on the secondary transfer belt. The collection roller is driven by another drive mechanism and thereby rotates in a state contacting with the cleaning brush to collect toner from the cleaning brush. The collection roller rotates in such a manner that the collection roller and the cleaning brush move in the same direction with each other at a contact area between the collection roller and the cleaning brush. The controller controls the drive mechanism such that the circumferential speed ratio of the collection roller with respect to the cleaning brush is greater than one and smaller than two.
