A syringe includes a body and a plunger movably disposed within the body. The plunger includes a wall having an inner surface and one or more inwardly projecting flanges disposed on the inner surface of the wall. Preferably, the inner surface of the wall defines a retaining shoulder formed along an axial plane thereof and the inwardly projecting flanges are radially spaced along the interior surface of the wall and extend in a longitudinal direction proximal to the retaining shoulder. The syringe may be used with an injector including a drive member. The drive member preferably includes at least one retaining member adapted to engage the retaining shoulder of the syringe plunger to allow the drive member to retract the plunger with the body of the syringe. Further, the drive member preferably includes one or more outwardly extending flange members adapted to be engaged by the inwardly projecting flanges of the syringe plungers. The outwardly extending flange members are operably linked to the at least one retaining member such that, when the syringe body is rotated and the inwardly projecting flanges on the plunger engage and move the outwardly extending flange members on the drive member, the at least one retaining member on the drive member is retracted and disengaged from the retaining shoulder of the syringe plunger.

The invention relates to a water surface garbage cleaning ship. In the invention, a ship body is of an dual-body design, and the water surface garbage cleaning ship is composed of a detection and navigation system, a collection system, a garbage treatment system, a garbage unloading system and a propulsion system; and the water surface garbage cleaning ship can have three working modes, namely a free navigation mode, a landing operation mode and a non-landing operation mode. The water surface garbage cleaning ship can realize autonomous navigation and work, unmanned operation, full automation, good cleaning effect, strong flexibility, smoothness in working, safety and reliability by using the detection and navigation system to detect a region with garbage on the water surface. A scraper bucket chain network type collection and transmission device designed in the water surface garbage cleaning ship can realize the combination of continuous and intermittent work of recovery, thereby being energy-saving and high-efficient. Simultaneously, the device can change the amplitude up and down by hydraulic drive and fish floating objects in different water depths faster and more effectively.A satellite ship is designed for collaborative collection, thereby having better flexibility and high efficiency. The shoreside water surface floating objects and semi-floating objects are recovered and taken onto the ship by using a hydraulic rotary water spray gun to spray water.

In a coating and developing apparatus that forms a resist film on substrates such as semiconductor wafers, and develops substrates exposed by an aligner, times after the aligner unloads substrates until heating units (PEB) start heating the substrates are kept uniform. Exposed wafers are prevented from being left stagnant in an interface portion disposed between a region in which resist is coated and developed and the aligner. In the region in which resist is coated and developed, a first transferring means that successively executes transportation cycles to transfer substrates from upstream side modules to downstream side modules in a flow of processes of substrates. N heating units (PEB) are disposed (n is for example 5). Exposed wafers loaded into the heating units (PEB) are unloaded by the first transferring means after (n−1) cycles including the transferring cycle of the first transferring means have elapsed.

A hard disk drive holding device includes a holder and at least a sliding trench. A hard disk drive is installed into the device quickly and simply through a sliding trench with an opening on a surface of the holder and is constrained tightly due to an inclination of the lateral inner surface in the sliding trench. The sliding trench may also narrow such that the hard disk drive is also constrained in a different direction and is held firmer.

A carrier system equipped with a fine movement stage holding a mounted wafer and can move along a predetermined plane, a chuck main section which holds the wafer above a predetermined position and can move vertically, and vertical movement pins supporting the wafer held by the chuck main section on the fine movement stage from below when the fine movement stage is positioned at the predetermined position and are vertically movable. A controller drives the chuck main section and the vertical movement pins downward until a lower surface of the wafer comes into contact with the fine movement stage while maintaining a hold state by the chuck main section to the wafer and a support state by the vertical movement pins to the wafer, and when the lower surface of the wafer comes into contact with the fine movement stage, the hold state and the support state are released.

The present invention relates to a dump truck or large mining truck, comprising a dump body for the transport of overburden or the like, a first hydraulic circuit having a first pump device for the actuation of the dump body as well as a second hydraulic circuit having a second pump device for the actuation of a steering and/or of a braking device of the dumper truck chassis and/or an auxiliary truck element. In accordance with the invention, the said first, second and/or a further hydraulic circuit having are connected to one another by a valve device which is controlled by a control device such that the plurality of hydraulic circuits cooperate in an unloading mode and actuate the dump body together and, on the other hand, the hydraulic circuits work separately in a travel mode so that the second hydraulic circuit and/or any further hydraulic circuit is separated from the dump body and its actuator device. The performance of the pump devices are added so-to-say by the combination of the hydraulic circuits, whereby a fast unloading of the dump body can be achieved despite the huge load. On the other hand, the valve device can uncouple the hydraulic circuits from one another, whereby the second hydraulic circuit can be utilized specifically only for the steering and/or the braking device in the travel mode.

The invention discloses a system and a method for dotting level survey dots of wings and a vertical tail of an airplane.
