A method of assembling a fastener structure on a plate body is introduced. The fastener structure includes a body portion and a fastening body. The body portion has a solderable layer, and the solderable layer is soldered to a plate body. The fastening body combines movably with the body portion. The fastening body has a head and a fastening portion. The body portion or the fastening body is provided on the plate body for soldering after it is picked up by a tool so that the body portion can combine with the plate body. Also, the body portion or the fastening body combines with an assisting pickup unit, and the fastener structure is provided on the plate body for soldering after it is picked up by a tool through the assisting pickup unit so that the body portion can combine with the plate body.

A heat sink mounting configuration is provided that is configured to prevent the heat sink from damaging ball grid arrays (BGA) of an application specific integrated circuit (ASIC) mounted on a printed circuit board (PCB) when the line card is subjected to vibrations and shocks. The heat sink mounting configuration may include a set of screws configured to be at least partially disposed within the apertures of the heat sink to secure the heat sink to the PCB. The mounting configuration includes a resilient member and a spacer disposed around the screws proximate to the apertures. The resilient members are configured to bias the heat sink against the ASIC to maintain the heat sink in contact with the ASIC. The spacers are configured to prevent the heat sink from impacting the ASIC with forces large enough to damage the BGA when the line card is subjected to vibrations and shocks.

The present invention provides a means of easily attaching and detaching a member that reinforces an envelope of a balloon to and from the envelope. Balloon 1 according to an embodiment of the present invention comprises Inner Member 121 and Outer Member 123. Each of Inner Member 121 and Outer Member 123 is a disk-shaped member made of a plastic, a light metal, or other lightweight material. Inner Member 121 and Outer Member 123 are attached to Envelope 11 by tightening Bolts 125 and Nuts 126, with Envelope 11 therebetween. A donut-shaped Rubber Seal 122 is located on the surface of Inner Member 121 in contact with Envelope 11, and a donut-shaped Rubber Seal 124 is located on the surface of Outer Member 123 in contact with Envelope 11. Rubber Seal 122 and Rubber Seal 124 are pressed tightly against Envelope 11 as Bolts 125 and Nuts 126 are tightened, and Holes H2 provided in Envelope 11 to accommodate Bolts 125 are sealed.

A mask frame support unit includes a case, a protruding body extending below the case, and a station having a flat head disposed above the case. The protruding body includes a tapered region and a cylindrical region. The tapered region includes a first end having a first diameter coupled to the case and comprising a second end having a second diameter opposite the first end. The second diameter is less than the first diameter, and the tapered region is coupled to the cylindrical region at the second end. The case houses a number of components including an upper receiving plate in contact with the station, a lower receiving plate disposed underneath the upper receiving plate, a flat head unit movement support mechanism disposed between the lower receiving plate and the body, and a centering component.

A blind bolt and tool is used for fastening a bolt through a hole in a structure when only one side of the structure is accessible. A receiver is formed on the tip end of a bolt shaft opposite from a bolt head. Internal threads are formed within the receiver proximate an outward end, and a hex socket is formed in the inward end of the receiver. External threads and a guide are formed on a tip of the tool, and the external threads mate with the internal threads in the receiver to hold the bolt during installation. A hex key on one end of the tool engages the hex socket in the receiver so that the tool may impose a torque on the bolt when a nut is being tightened on the bolt. In another embodiment, a splined tip is formed on the end of the bolt. The tip is designed to shear off when a sufficient torque is applied. Also, a shim is configured to fit between structures held together by the blind bolt.

A fastener including a screw part and a handle part. The screw part includes a head portion and a body portion that are connected to each other. A diameter of the body portion is smaller than a diameter of the head portion. The head portion includes a recess on a side of the head portion located away from the body portion. The handle part is pivotally connected to the head portion and pivotable between an operation position and a bent-down position. When the handle part is in the operation position, the handle part is partially located on a side of the head portion located away from the body portion. When the handle part is in the bent-down position, the handle part is located away from the side of the head portion located away from the body portion.

A durable captive bolt assembly for use with subterranean utility boxes is described. The disclosed bolt assembly includes a fastener, a conical spring, a rigid washer, a deformable washer, and a bushing. The point and threads of the fastener are designed to clear debris from an internally threaded nut and reduce or eliminate cross threading, galling, and electrolysis.

A curtain wall panel mounting system comprises a ball anchor seated in a spherical cavity or a cylindrical cavity with plugs nearly abutting the ball of the anchor. A stem extends from the ball to connect to the wall panel. Under seismic stress, the ball may swivel within the cavity so as to pivot the anchor, allowing the attached wall panel to angle itself to accommodate the stress.
