Disclosed herein are exemplary embodiments of linings or liners (e.g., liners with corner reinforcement, etc.), methods of providing a liner or lining for a tank, and methods and apparatus for providing additional protection and/or reinforcement at the corners of a liner or lining. In an exemplary embodiment, a method generally includes positioning and attaching one or more corner attachments at one or more corners of a liner that are formed between the bottom and the one or more sides of the liner. The one or more corner attachments may be configured to provide additional protection and/or reinforcement at the one or more corners of the liner.

The present invention provides a sealing process for a secondary battery of the present invention, which thermally fuses and seals a sealing portion that extends along an edge surface of a battery case, the sealing process comprising: an arrangement operation of disposing the sealing portion of the battery case between an anvil and a horn; a first region-fixing operation of pressing and fixing a first region of the sealing portion through the anvil and the horn; and a first region-primary sealing operation of applying an ultrasonic wave to the first region of the sealing portion through the horn at a set frequency and a set amplitude for a set time, thereby thermally fusing the first region of the sealing portion.

Curable prepregs possessing enhanced ability for the removal of gases from within prepregs and between prepreg plies in a prepreg layup prior to and/or during consolidation and curing. Each curable prepreg is a resin-impregnated, woven fabric that has been subjected to a treatment to create an array of openings in at least one major surface. Furthermore, the location of the openings is specific to the weave pattern of the fabric.

An inspectable joint in a medical device is disclosed that includes at least one medical-grade tube having an end, a medical-grade fitting having at least one joining surface configured to accept the end of the tube, and a joining material disposed between the tube and the joining surface. The joining material includes a first component configured to couple the tube to the fitting and a second component configured to provide observable evidence of the presence of the joining material between the tube and the joining surface.

A joining method for joining a resin member and a metal member by heating is provided. Joining of the resin member and metal member is performed by heating a joining interface of the resin member and metal member to a temperature in a range of equal to or higher than a decomposition temperature of the resin member and lower than a temperature at which gas bubbles are generated in the resin member and by cooling a surface of the resin member on the opposite side from a joining surface thereof with the metal member to a temperature that is lower than the melting point of the resin member.

A bonding device for charging a liquid material into a space between plate-shaped members for bonding them together in situ, in which the liquid material may be prevented from exuding from the space between the plate-shaped members. The bonding device includes pair retaining base members for retaining the pair plate-shaped members facing each other, and a retaining base member movement unit for causing movement of the retaining base members towards and away from each other. The bonding device also includes an illumination unit that illuminates curing light to a photo-curable liquid material charged between the pair plate-shaped members held by the pair retaining base members, and a sensor that detects the wetting spreading state of the liquid material charged between the pair plate-shaped members.

An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

A polar functional group is added onto a surface of a metallic member. A resin member contains an adhesive functional group. The adhesive functional group and the polar functional group attract each other. A method for joining the metallic member and the resin member to each other includes: heating a junction between the metallic member and the resin member while pressing the metallic member and the resin member against each other with a first load; maintaining temperature of the junction higher than melting temperature of a resin that structures the resin member while pressing the metallic member and the resin member with each other with a second load smaller than the first load; and cooling the junction to temperature lower than the melting temperature while pressing the metallic member and the resin member against each other with a third load larger than the second load.

A pipe joining material for connecting pipes and fittings and a method of making a pipe joining material are provided. The pipe joining material may include a thermoplastic material such as polyvinyl chloride (PVC) and/or chlorinated polyvinyl chloride (CPVC) and a bonding agent for the thermoplastic material.

A method of fabricating a composite assembly may include providing a first laminate and a second laminate respectively formed of first and second composite plies, and having a respective first and second cured section and a respective first and second uncured section. The method may further include interleaving the first composite plies in the first uncured section with the second composite plies in the second uncured section to form an interfacial region. The method may additionally include curing the interfacial region to join the first laminate to the second laminate and form a unitized composite assembly.
