09851040 · 2017-12-26 · ·

A liner assembly and method for lining a damaged pipe junction between a main and lateral pipe is provided. The liner assembly includes a main liner member and a lateral liner tube. A collar disposed near the juncture between the main liner member and lateral liner tube is impregnated with a liquid hydrophobic or hydrophilic material capable of curing in a flexible or rigid state with the material expanding in the presence of water. The hydrophobic or hydrophilic material can also be applied without the use of the collar. When the liner assembly is pressed against the main and lateral pipes, a portion of the hydrophilic or hydrophobic material is forced into the damaged pipe junction.

20230202160 · 2023-06-29 ·

The method controls a discharging gap suitably and easily, effectively damages an adhesive which is an insulator by a shock wave generated in a discharging gap, and disassembles the composite material into conductors. The method of disassembling the composite material includes: a protrusion formation step S1 of forming an elastic protrusion in a predefined part of a first conductor; a composite material formation step S2 of applying an insulator on a surface of the first conductor on which the protrusion stands and bonding or joining the first conductor and a second conductor facing a protruding end of the protrusion with the insulator to form a composite material 1; and a separation step of applying an electric pulse between the first conductor and the second conductor to damage the insulator, thereby separating the first conductor and the second conductor from each other.

Separation apparatus

A yield in a separation process is improved. A separation apparatus which enables easy separation in a large-area substrate is provided. The separation apparatus has a function of dividing a process member into a first member and a second member and includes a support body supply unit, a support body hold unit, a transfer mechanism, a direction changing mechanism, and a structure body. The structure body bonds a support body to a surface of the first member. When at least part of the process member is located between the direction changing mechanism and the structure body or the pressure applying mechanism, the shortest distance between the direction changing mechanism and a first plane including the surface of the first member is longer than the shortest distance between the first plane and the structure body or the pressure applying mechanism.

Production of very small or thin dies
11688638 · 2023-06-27 · ·

A system to manufacture a plurality of dies may include an etching tool, an electrically-conductive-adhesive-composition, a heat-applying-extraction-tool and a porous substrate cooperating with an evacuation component. The etching tool uses an ion beam that is configured to singulate a plurality of dies on a wafer with an ion etching process. The electrically-conductive-adhesive-composition is located between the wafer and a porous substrate carrying the wafer during the ion etching process. The electrically-conductive-adhesive-composition adheres the wafer to the porous substrate to keep the dies in place during the ion etching process. The electrically-conductive-adhesive-composition also aids in conducting electrons away from the wafer as a drain during the ion etching process. The heat-applying-extraction-tool applies heat to an individual die during a handling process of the manufacturing process in order to melt the electrically-conductive-adhesive-composition through the porous substrate to an evacuation component in order to then pick up an individual die singulated from the wafer.

SYSTEMS AND METHODS FOR TRANSFERRING GRAPHENE

The present disclosure is directed towards systems and methods for transferring graphene from the surface of one substrate to another. In one particular embodiment, the graphene layer is grown on a surface of a first substrate, where the bottom of the first substrate is then affixed to the surface of a second substrate. The second substrate may include material made of a rigid or semi-rigid composition to provide structural support and backing to the first substrate. The graphene layer may then be delaminated from the first substrate and transferred to a target surface, such as the surface of an electronic device or biosensor.
