摘要:
A reinforcing arrangement for reinforcing a joint portion between two support units of a foldable furniture object, comprising a first mounting unit which comprises a first mounting body and a first guiding member outwardly protruded from the first mounting body mounting on the first support unit; a second mounting unit which comprises a second mounting body and a second guiding member or a second guiding groove complimentary to and moveably engaging with the first mounting unit to define a maximum extending angle of movement, thereby the first and second support unit are guided to lock into position at an unfolded position at the maximum extending angle and to unlock at a folded position; and a connecting unit pivotally connecting the first support unit and the second support unit between which the two mounting units are positioned, thereby the joint portion is reinforced.

A foldable furniture includes a retention structure including a left retention coupler and a right retention coupler coaxially and overlapping with the left retention coupler side-by-side in a rotatably movable manner via a pivot joint. The left retention coupler includes at least a left retention member protruding towards the right retention coupler. The right retention coupler includes at least a right retention member protruding towards the left retention coupler, wherein when the foldable furniture is pivotally folded at an unfolded position, the left and right retention couplers are coaxially rotated at an opposite direction until the left and right retention members are biased against each other. Therefore, the retention structure enhances the structural supportive force of the foldable furniture to evenly distribute the loading force on the foldable furniture so as to enhance the stabilization of the foldable furniture.

A gas turbine case is provided including an outer case surface, and a channel portion formed as a recessed area extending radially inwardly into the outer case surface. The channel portion extends about a circumference of the case. An outer flow jacket is attached to the outer case surface and extends over the channel portion to define an enclosed cooling passage along the outer case surface. At least one inlet passage and at least one outlet passage are provided in fluid communication with the enclosed cooling passage to convey air to and from the cooling passage.
摘要:
A method of operating an immersion lithography system, including steps of immersing at least a portion of a wafer to be exposed in an immersion medium, wherein the immersion medium comprises at least one bubble; directing an ultrasonic wave through at least a portion of the immersion medium to disrupt and/or dissipate the at least one bubble; and exposing the wafer with an exposure pattern by passing electromagnetic radiation through the immersion medium subsequent to the directing. Also disclosed is a monitoring and control system for an immersion lithography system.

A foldable table includes a tabletop and two leg frames for supporting the tabletop, each of the leg frames having a transverse member pivotally attached to a underside of the tabletop and a standing leg extended from the transverse member and pivotally moveable with respect to the tabletop. A retaining element having a first end pivotally attached to the transverse member and a second end pivotally attached to the standing leg of the other transverse member. The retaining element has an adjustable length adapted for lengthening to become longer than a distance between the transverse members of the leg frames as the leg frame is erected, thereby providing lateral support for the erected leg frame.

A foldable banquet table and bench set includes a panel unit, a support unit, and an attachment frame. The panel unit includes a tabletop and at least a bench top. The support unit includes a table leg frame foldably coupled at the tabletop to form a foldable table, and a bench leg frame foldably coupled at the bench top to form a foldable bench, wherein the table leg frame is longer than the bench leg frame. The table leg frame and the bench leg frame are detachably and spacedly coupled at the attachment frame, such that the attachment frame not only retains a distance between the foldable table and the foldable bench but also interlocks the foldable table and the foldable bench at their unfolded positions by different leg heights.

A dual side post, which is arranged for a multiple shelving apparatus constructed by two or more shelving apparatus each including a plurality of shelf supporting beams and a plurality of cross members, includes a plurality of vertical posts. Each vertical post has an inner attachment surface, a plurality of attachment slots spacedly formed at the inner attachment surface, and a retention slot formed on the inner attachment surface for coupling with the cross member. The attachment slots are lined up in two columns that the retention slot is located between the two columns of the attachment slots. One of the vertical posts serves as a common post that the two columns of the attachment slots thereof are arranged for respectively coupling two of the shelf supporting beams at opposite directions so as to interconnect two or more shelving apparatus to form the multiple shelving apparatus.

A frame of a shelving apparatus includes a plurality of vertical posts, a plurality of cross members, and a plurality of shelf supporting beams. Each vertical post has an inner attachment surface, a side surface, and a plurality of attachment slots formed at the inner attachment surface. Each shelf supporting beam includes a beam member and two post lockers provided at two ends of the beam member respectively. Each post locker includes an extension wall biasing against the side surface, a locker wall biasing against the inner attachment surface, and a locking element provided at the locker wall to selectively engage with one of the attachment slots so as to detachably couple the shelf supporting beam between the vertical posts at a position that the beam member is extended between the side surfaces of the vertical posts.

A foldable post for a shelving apparatus includes an upper post member, a lower post member, and a post joint for connecting the upper and lower post members end-to-end. The post joint includes an engaging tongue extended from an end portion of the first post wall of the upper post member, an engaging groove provided at an end portion of the first post wall of the lower post member, and a pivot hinge pivotally coupled the second post walls of the upper and lower post members, such that when the upper and lower post members are pivotally moved to engage the engaging tongue with the engaging groove, the upper and lower post members are interlocked and coupled with each other end-to-end.

A shelf supporting beam configuration for a shelving apparatus, includes a shelf platform, a plurality of shelf retaining members, and shelf supporting arrangement. Each shelf retaining member has two coupling ends for detachably coupling with two vertically extending posts of the shelving apparatus, and first and second longitudinal edges extended between the two coupling ends to form a boundary frame. The shelf supporting arrangement is integrally extended from each of the shelf retaining members between the first and second longitudinal edges to rigidly support the shelf platform within the boundary frame.
