A securing assembly for an article, said assembly being capable of securing against both tensile and compressive forces, and including: a casing which in use is rigidly attached to an article to be secured; a securing rod which is adapted to be releasably connectable between a floor underlying an article to be secured and said article; the securing rod providing a first portion at one end thereof and a second portion at the other end thereof, and a third portion having reduced strength compared to said first and second portions, between said first and second portions; a bearing dimensioned and arranged to support at least a major portion of said third part of said rod; said casing being arranged to completely surround and contain at least said third portion of said rod; said casing being in load transmitting engagement with said rod.

The accessory attachment structure for attaching an accessory to a steel plate-reinforced concrete structure, the steel plate-reinforced concrete structure being provided with a steel plate frame, bars fixedly installed on an inner face of an outside steel plate, and concrete, the accessory attachment structure includes an attachment plate in which one face thereof is attached to the outside steel plate and the accessory is attached to the other face thereof. The size of the other face of the attachment plate is larger than that of a whole attachment face to be attached to the attachment plate of the accessory, the size if the one face is equal to or greater than the other face, and the length of the attachment plate in any direction along the one face of the attachment plate is at least two times greater than a mutual interval between the bars.

A connector may couple to a non-cylindrical composite tubing having at least two lateral sides disposed in parallel and an open end. The connector may comprise first and second bonding plates adhered to an inner surface of the two lateral sides via an epoxy adhesive uniformly distributed. The first and second bonding plates may each have a distal lateral face defining a plurality of first threaded holes accessible at the open end of the composite tubing. The connector may also comprise an end plate having a plurality of first and second slotted holes disposed substantially in parallel and each aligned with an associating one of the first threaded holes. The connector may also comprise end plate fasteners loosely inserted through the first and second slotted holes and engaged with the first threaded holes. The end plate may also comprise one or more attachment points.

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 on a non-diffusable type, such as aluminum nitride, alumina, beryllium oxide, and zirconia, 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 coupling structure includes a welding member formed of resin and a welded member that is formed of resin and to which the welding member is welded. In the welding member, a region that is welded to the welded member on the rear side in a predetermined direction is smaller than a region that is welded to the welded member on the front side in the predetermined direction.

A connector for non-cylindrical composite tubing and methods for making the same. The method may involve assembling a connector for a non-cylindrical composite tubing by loosely fastening a pair of bonding plates to an end plate; arranging the bonding plates in an inward configuration; applying an epoxy adhesive onto the outer faces of the bonding plates, inserting the bonding plates into the open end of the composite tubing, inserting the bonding plate fasteners through the through-holes of the composite tubing and tightly fastening the bonding plate fasteners into the bonding plates until the bonding plates engage against the inner surface of the composite tubing until the epoxy adhesive is uniformly distributed. The method may also include steps of removing the bonding plate screw fasteners and adding shims between each bonding plate and the inner surface of the composite tubing in order to maintain a predetermined thickness of the epoxy adhesive.

A method for the joining of ceramic pieces with a hermetically sealed joint comprising brazing a continuous 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 time at 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.

Provided are a connector and a connection system for concrete barriers. The connector is configured to slip-fit into a cross-shaped gap formed between the concrete barriers. The connector includes a saddle member and a fork member. The saddle member includes a base plate and peripheral plates. The peripheral plates extend at angles from the base plate to define open ends of the saddle member. The fork member extends below the base plate of the saddle member. The fork member includes an elongated base, flanges, and legs. The elongated base extends between the peripheral plates. The flanges are transverse to the elongated base forming a cross-shaped structure with the flanges that extend toward the open ends of the saddle member. The legs extend separately from the elongated base.

A securing assembly for an article, said assembly being capable of securing against both tensile and compressive forces, and including: a casing which in use is rigidly attached to an article to be secured; a securing rod which is adapted to be releasably connectable between a floor underlying an article to be secured and said article; the securing rod providing a first portion at one end thereof and a second portion at the other end thereof, and a third portion having reduced strength compared to said first and second portions, between said first and second portions; a bearing dimensioned and arranged to support at least a major portion of said third part of said rod; said casing being arranged to completely surround and contain at least said third portion of said rod; said casing being in load transmitting engagement with said rod.

Connector to slip-fit into a cross-shaped gap between barriers. The barriers are engaged by a lock extending in the gap into slots through sidewalls terminating the barriers. The connector includes a saddle and fork. The saddle includes a base plate and peripheral plates. The base plate is to extend over the gap and partially atop the barriers. The peripheral plates are to be disposed over front and back walls of the barriers. The base plate and peripheral plates define open ends. The fork extends below the base plate and includes a base, flanges, and legs. The base is to he disposed atop the lock between the sidewalls. The flanges are disposed transversely to the base forming a cross-shaped structure to be disposed atop the lock with the flanges extended toward the open ends into the slots. The legs extend separately from the base to straddle the lock between the sidewalls.
