A method of fastening a second object to a first object includes: providing the first object with an attachment surface; providing the second object; placing the second object relative to the first object, with a resin composition in between the attachment surface and the second object, wherein the resin composition has a resin having a first viscosity and being in a flowable state; pressing the first and second objects against each other and causing mechanical vibration to act on at least one of the objects until the resin composition experiences a vibration induced activation, which includes at least one of reduction of the viscosity of the resin compared to the first viscosity and activation of particles dispersed in the resin. The pressing and mechanical vibration are continued or repeated until the resin has at least partially cross-linked and the viscosity of the resin is increased compared to the first viscosity.

The first electrode section (7a) and the second electrode section (7b) are formed such that the outer portion connected to the upper portion of the heating section (6) is thinner than the inner portion connected to the lower portion of the heating section (6). The heating section (6) and the first electrode section (7a) are interconnected by an R-shaped first connecting portion (21). The inner circumferential sloping surface of the heating section (6) and the second electrode section (7b) are interconnected by an R-shaped second connecting portion (22). The first and second connecting portions (21)(22) are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion (6b) is smaller than the thicknesses of the first and second connecting portions (21)(22).

A package including at least one bumper having an elliptical shape that extends from a first end to a second end along a first plane and having a protrusion that extends from a first front along a second plane; and a first tray having a first cavity that extends from a second front along the second plane, wherein the first cavity includes at least one groove configured and dimensioned to receive the at least one bumper is disclosed.

The present invention provides a thermal caulking device which can quickly heat and cool an object to be caulked with low electrical power. Provided is a thermal caulking device which caulks a portion of a plastic part 7 as an object to be caulked, the thermal caulking device including: a metal tip 3 having a pressing part 3a which presses the object to be caulked and a heating rod 3c which is provided upright at a center part of the pressing part 3a; heating means 10c for heating the heating rod 3c; a cooling pipe 9 which cools the heating rod 3c; cooling fluid supply means 4 for supplying a cooling fluid to the cooling pipe 9; a holder 1 which holds the metal tip 3 and the cooling pipe 9 so that the cooling pipe 9 delivers the cooling fluid toward the heating rod 3c; and control means 6 for controlling the heating means 10c and the cooling fluid supply means 4, wherein the control means 6 heats the pressing part 3a from the heating rod 3c by the heating means 10c, and after the object to be caulked is thermally caulked by the pressing part 3a, supplies the cooling fluid from the cooling fluid supply means 4 to the cooling pipe 9 to cool the pressing part 3a from the heating rod 3c.

A connection system has a first adhesion segment, on which a first connection region is formed, a second adhesion segment, on which a second connection region is formed, and a solidifiable liquid connection substance for connecting the two adhesion segments in a material fit, wherein at least one of the two connection regions is formed flexibly, such that, when the liquid connection substance is introduced between the two connection regions which are opposite one another in an assembly arrangement of the two adhesion segments, a material connection is formed between the two connection regions automatically as a result of the elastocapillary effect via the liquid connection substance.

A mat unit includes a plurality of gaps defined by a first layer that are in open communication with gaps defined by a second layer so as to permit debris to fall entirely through both gaps to pass completely through the mat unit. The mat unit is part of an omnidirectional mat cleaning system that includes a first direction of travel above the mat unit extending through a door opening defined by a building structure. A different second direction of travel is above the mat unit extending through the door opening or another door opening defined by the building structure. The mat unit is installed on a floor adjacent the door opening. The mat unit cleans shoes regardless of the direction of travel traveled above the mat unit.

An automated fastener insert installation system for composite panels is provided. A first module receives and secures a composite panel with respect to an origin of a first coordinate system, wherein the composite panel has opposed major surfaces and defines an insert-receiving orifice extending through one of the major surfaces, and is secured such that one of the major surfaces is externally accessible. A second module engages each of a plurality of fastener inserts with an installation aide. Third module determines a configuration of the orifice defined by the composite panel, selects a corresponding one of the fastener inserts engaged with the installation aide, inserts the selected fastener insert into the orifice, and dispenses an adhesive material through the installation aide and into the orifice about selected fastener insert such that the adhesive material secures the selected fastener insert within the orifice. Associated systems are also provided.

A method for producing a composite component, which has a first section and a second section connected to the first section, the first section including a metallic material, the second section including a plastic, the first section having a first base region and projections provided on the first base region, and the projections provided on the first base region being anchored in the second section in order to bring about the connection between the first section and the second section, includes: manufacturing the first base region of the first section; creating the projections directly on the first base region by way of an additive manufacturing method; and connecting the second section to the first section.

The present invention relates to a nozzle for cleaning a substrate capable of spraying deionized water for cleaning a substrate to the substrate, the nozzle including a first body made of a resin material and provided with a first part of a deionized water passage and a deionized water supply hole to supply the deionized water, a second body made of a resin material and provided with a second part of the deionized water passage and a plurality of spray holes to spray the deionized water to the substrate, a fusible protrusion provided in the first body or the second body along the deionized water passage and configured such that a part thereof is fused during ultrasonic welding, so as to couple the first body and the second body together, and a fusible protrusion accommodating part formed in the first body or the second body to accommodate the fusible protrusion.

A package including at least one bumper having an elliptical shape that extends from a first end to a second end along a first plane and having a protrusion that extends from a first front along a second plane; and a first tray having a first cavity that extends from a second front along the second plane, wherein the first cavity includes at least one groove configured and dimensioned to receive the at least one bumper is disclosed.
