A connection assembly includes a housing, an adaptor and a conducting element. The housing has a chamber and an opening communicating with the chamber. The adaptor has a first through hole. The adaptor is at least partially connected outside the housing. The opening communicates with the first through hole. The conducting element penetrates through the first through hole and the opening. The conducting element is detachably connected with the adaptor.

T-slot connection insert apparatuses comprise a first connector tab having a first connection aperture therein and a second connector tab having a second connection aperture therein, wherein the first connector tab and the second connector tab are connected together via a bridging span.

Container retention and release apparatus are disclosed. An example container retention and release apparatus includes an actuator a swaybrace and retention assembly pivotally coupled to the actuator. The swaybrace and retention assembly pivot relative to the actuator between a first position to retain a container and a second position to release the container.

For the economical and energy-efficient use of a PV system having upright, in particular bifacial, PV modules and to substantially avoid shading of the PV modules, a supporting structure which is simple to manufacture and install is provided, that is constructed by vertical posts, which are connected to one another at intersecting points, and horizontally running cross-members such that rectangular mounting areas are provided for the individual PV modules. The posts and cross-members are formed in a material-saving manner by conventional profiles, and a division of the posts into two interconnectable sections substantially facilitates the assembly. An electrical connection is provided such that active surfaces which are arranged one above another can be operated at different electrical operating points and such that electrical lines are formed which are operated separately from one another and are arranged in a horizontally running manner. This minimizes effects of shading of PV modules on the efficiency of the energy conversion.

Provided is a wiring unit that reduces spatial constraints and makes it possible to easily perform wiring work. The wiring unit is provided with: a plate on which a support surface for supporting electrical wires is formed; and a holding member for holding the electrical wires between the support surface and said holding member. The holding member comprises a plurality of holding pieces protruding from the support surface side. After being collapsed from an upright orientation in which the holding pieces stand upright so as to demarcate a guidance space in which the electrical wires are guided toward the support surface side, each of said holding pieces presses the electrical wires toward the support surface side and deforms toward a holding orientation in which the electrical wires are restricted from lifting up from the support surface.

A method for the joining of ceramic pieces with a hermetically sealed joint comprising brazing a layer of joining material between the two pieces. The wetting and flow of the joining material is controlled by the selection of the joining material, the joining temperature, the joining atmosphere, and other factors. The ceramic pieces may be aluminum nitride and the pieces may be brazed with an aluminum alloy under controlled atmosphere. The joint material is adapted to later withstand both the environments within a process chamber during substrate processing, and the oxygenated atmosphere which may be seen within the shaft of a heater or electrostatic chuck.

A mounting system for mounting an element to a surface includes a mounting post having a base configured for mounting to a surface. The mounting post is threaded on an outer surface. A mounting plate is configured for being secured to the element to be mounted and has a center opening for receiving the mounting post so that the mounting plate is freely movable along the mounting post. An adjustment plate includes a threaded opening to receive the mounting post. The adjustment plate is configured to incrementally rotate on the threaded mounting post for adjusting the position of the adjustment plate along the mounting post and with respect to the surface. The adjustment plate is configured for being fixed to the mounting plate at a plurality of incremental positions of the adjustment plate to secure the mounting plate at a selected position along the mounting post and thereby adjust the distance between the surface and mounted element.

A mounting system for mounting an element to a surface includes a mounting element having a base and a threaded shaft extending from the base along an axis. The base is configured for mounting to a surface. An incremental nut rotates on the threaded shaft and moves up and down on the shaft. A fitting is coupled with the incremental nut and the fitting is further configured for coupling with an element to mount the element to a surface at a selected height above the surface. Apertures are formed in the incremental nut and fitting and the apertures of the incremental nut aperture and fitting are aligned at a plurality of rotational positions of the incremental nut along the threaded shaft for adjusting the height of the nut and fitting. In one embodiment the threaded shaft includes an aperture that is aligned with the incremental nut apertures for locking the nut at a selected height.

Provided is a joint component manufacturing method for reducing occurrence of burrs upon bonding between a first member having a hole and a second member having a shaft portion and firmly bonding both members. In the method for manufacturing a joint component 100, a hole-side weak press-fit portion 112 is formed at a hole 111 of a flat plate ring-shaped first member 110. Moreover, each of a shaft-side weak press-fit portion 122 and a shaft-side strong press-fit portion 124 is formed at a shaft portion 121 of a cylindrical second member 120. The hole-side weak press-fit portion 112 and the shaft-side weak press-fit portion 122 are defined by a first weak press-fit interference Lw1 formed thinner than a first strong press-fit interference Ls1. The shaft-side strong press-fit portion 124 is defined by a first strong press-fit interference Ls1 as the minimum necessary press-fit interference for electric resistance welding upon electric resistance welding between the hole 111 and the shaft portion 121.
