An exposure apparatus includes a projection optical system for projecting an image of a pattern of a reticle onto an object, via a fluid that is filled in a space between said projection optical system and the object, a vibrator part for vibrating at least one of the fluid, the object, and the projection optical system, and a controller for controlling the vibrator part so that the vibration of at least one of the fluid, the object, and the projection optical system becomes a tolerance during a processing of the object.

A system for forming a retractable cargo support for use over the bed of a truck is disclosed. The system includes a slide system with an elongated slide base having an upwardly opening U-shaped cross-section, an intermediate slide that is slidably mounted within the U-shaped cross-section of the slide base has an upwardly opening U-shaped cross section, and a top slide. The top slide includes a downwardly opening U-shaped cross-section, and is adapted for nesting in a sliding relationship within the U-shaped cross-section of the intermediate slide. A load surface is attached to the top slide, so that mounting the slide base to the bed of the truck allows the load surface to be slid in and out of the bed of the truck.

A clamp structure for a tonneau cover is disclosed and mounted to one frame section of a tonneau cover for releasably securing the frame section on a cargo bed of a pick-up truck. The clamp comprises: a foundation rail having two side grooves and a recess formed between the two side grooves; and a sliding block having two side hangers extended into and slidably moving along the two side grooves and a pivotal portion received in the recess; a clamp bolt; a grip element; and a handle. The side hangers of the sliding block is used to slidably move along the side grooves of the foundation rail, so that the sliding movement of the clamp structure pivotally connected to the sliding block in relation to the foundation rail is more stable and smooth based on two strong support points of the two side hangers in the two side grooves.

A tonneau cover apparatus for attaching a flexible cover about a cargo box of a vehicle, preferably a pickup truck. The apparatus preferably includes, a support frame removably attached about the perimeter of a cargo box of the vehicle, an elongated end plate attached to an end of the flexible cover, an end plate engagement member attached to the support frame, preferably one on each side of the support frame, and a locking member movably attached to the end plate. The end plate is preferably attached to an end of the flexible cover and is configured to cooperatively engage and pivot with respect to the end plate engagement member or members into and out of a fixed stretching position wherein the flexible cover can be correspondingly be tensed and relaxed. The end plate may be retained in the fixed stretching position by the locking member, in alternate embodiments, a plurality of locking members are provided, preferably locking members that slide within a channel in the end plate. In preferred embodiments the locking member or members are spring biased toward a locking position where the locking member engages a flange of the support frame to prevent the end plate from moving out of the fixed stretching position.

A tonneau system for a cargo box of a pickup truck having a framework. The framework having a cross bow member for supporting a cover and being positionable generally over the cargo box of the pickup truck. The tonneau system further includes a latch assembly pivotally coupled to the cross bow member. The latch assembly is positionable in a latched position engagable with the cargo box of the pickup truck, an unlatched position disengagable with the cargo box of the pickup truck, and a nested position substantially retracted from the unlatched position and received within the cross bow member. The tonneau system may further include a biasing member that is substantially received within a portion of the latch assembly to improve consistent spring rates across the actuation range.

A Collapsible Bed Cap for Trucks is disclosed. The cover has a plurality of collapsible or sectioned ribs extending longitudinally along the length of the bed in order to provide structural rigidity to the cover. The cap or cover is sectional and detachable such that it can be disassembled and/or collapsed and then stored in a single bag. When assembled, the cover has a tight, aerodynamic and aesthetically pleasing material cover to protect truck bed contents from environmental effects. The bed cover further has front and rear arches for strength; these arches are also collapsible for storage. Still further, the cover may be removed from a bed while assembled so that it might be converted into a free-standing awning.

A roll tarp system for efficiently covering a heaped load. The roll tarp system includes a tarp attached to a side of a container, a roller attached to the tarp opposite of the container, a rear bracket attached to a rear end of the container, a rear inner arm pivotally attached to the rear bracket, a rear outer arm pivotally attached to the rear inner arm, a front bracket attached to a front end of the container, a front inner arm pivotally attached to the front bracket, a front outer arm pivotally attached to the front inner arm, and an actuator attached to the front inner arm and the roller for rotating the roller. A rear spring and a front spring are attached to the brackets respectively for applying a closing bias force upon the inner arms respectively. A front bias member is attached between the front inner arm and the front outer arm.

A bi-fold hinge assembly for facilitating the more compact placement of a tonneau cover in a stowed position. The bi-fold hinge includes a first arcuate bracket and a second arcuate bracket, which are pivotable between a stowed position and a deployed position. The bi-fold hinge also includes a front base plate, where the second arcuate bracket is pivotally connected to the front base plate, and a rear base plate, where the first arcuate bracket pivotally connected to the rear base plate. The front base plate is connected to a front side rail, and the rear base plate is pivotally connected to a rear side rail. The front side rail and the rear side rail are part of a frame assembly used for supporting and controlling the movement of the tonneau cover as the tonneau cover is moved between the deployed position and the stowed position.

A tonneau cover assembly is provided having a plurality of substantially rigid panels inserted between the fabric and the bows and then locked into place and/or supported by snap-fit elements connecting to the peripheral frame of the tonneau cover. The snap-fit elements can also serve to positively locate the bows with respect to the frame. The panels can be closely dimensioned with respect to the distance across the frame or spaced somewhat to accommodate insertion about frame hinges and/or close fitting fabric, bows and frames. Two sided adhesive tape can be used between the panels and the snap-fit elements and the bows to maintain panel placement in the event that the assembly is to be a permanent aspect of the tonneau cover. Panels can also be perforated for weight reduction and/or cost savings without significant loss of theft security. Panels can be padded for impact absorption without permanent deformation so as to maintain tonneau cover attractiveness despite significant wear and tear during use.
