A metal-resin joining device joins a thermoplastic resin plate (12) to a metal plate (13) by melting the resin plate (12) in contact with the metal plate (13) through heating an exposed face of the metal plate (13) by one-sided resistive heating. The metal-resin joining device has a center electrode (24a) that is brought in contact with the metal plate (13) and a peripheral electrode (24b) that is brought in contact with the metal plate (13) to annularly surround the center electrode (24a) and to which a current flows from the center electrode (24a) via the metal plate (13), wherein the peripheral electrode (24b) is made of a metal material having a higher electrical resistance than the center electrode (24a).

A method of manufacturing a liquid ejecting head including a first component and a second component, the method includes a heating step of heating an adhesive that bonds and cures the first component and the second component to plasticize the adhesive, a disassembling step of releasing a bonding state between the first component and the second component by the heating step, and a replacing step of replacing at least one of the first component and the second component with a new product after the disassembling step.

The invention relates to a device for setting a setting element having a first plastic material in a component having a second plastic material, comprising a rotational advancing unit, by means of which the setting element can be rotated about an axis of rotation and simultaneously an axial force acting in the direction of the axis of rotation can be applied to the setting element in order to drive the setting element into the component, a friction welding joint thereby being produced between the setting element and the component, a differential-distance measuring apparatus for measuring the differential distance between a surface of the component and a surface of the driven setting element, and a control unit for controlling the rotational advancing unit in dependence on the measured differential distance.

A plastic containing assembly is provided with a container including a containing member, a front reduced section formed with the containing member, and a shoulder between a front end of the containing member and the reduced section; and a hollow, externally threaded adaptor including an outer protrusion put on the reduced section, an inner projection inserted into both the front end of the containing member and the reduced section, a groove on an outer surface of the projection, a filler member between the groove and the protrusion, and an axial passage communicating with an open front end of the adaptor and the projection respectively. An ultrasonic welding machine may apply high-frequency ultrasonic acoustic vibrations to the filler member and melt same to join the shoulder, thereby forming a first joining layer; and melt a joining portion of the reduced section and the protrusion, thereby forming a second joining layer.

Provided is a molded article which contains a first enclosure; a second enclosure adjoined with the first enclosure; and a transparent member held by the second enclosure, each of the first enclosure and the second enclosure being independently made from a resin composition that contains a polyamide resin having a semi-crystallization time of 10 to 60 seconds, and a melting point of 200 to 280? C., and the transparent member having a pencil hardness of 8H or larger, and a linear expansion coefficient of 1?10.sup.?6 to 9?10.sup.?6/? C., where the semi-crystallization time means a time measured by depolarization photometry at a temperature 20? C. higher than the melting point of the polyamide resin, for a melting time of polyamide resin of 5 minutes, and at a temperature of crystallization bath of 150? C.

Embodiments are directed to a removable cap with a top hole and a seal with a heat induction closure for sealing an opening of a container. Advantageously, the cap and the seal do not need to be removed for a probe to access contents of the container, when used in a diagnostic analyzer, thereby eliminating operator steps of cap removal and seal peeling/perforation. Automated opening of the cap and seal combination is provided by puncturing the seal. The seal retains its opened shape required for unobstructed, non-contact probe access to contents of the container. The seal is comprised of three layers: a first polymer sealing layer capable of being heat-sealed to a container; an aluminum foil layer on top of the first polymer sealing layer, configured to heat seal the first layer by inductive heating; and a second polymer layer on top of the aluminum foil layer for protection.

The present disclosure provides a fitment. In an embodiment, a fitment is provided and includes a top portion, a base, and a channel extending through the top portion and the base for passage of a flowable material. The fitment is composed of a polymeric composition. The polymeric composition includes (i) from 70 to 90 weight percent of a high density polyethylene (HDPE) having a density from 0.940 g/cc to 0.970 g/cc, a melt temperature, Tm, greater than 125 C., and a melt index from 1 g/10 min to 50 g/10 min; and (ii) from 30 to 10 weight percent of an oletin based elastomer having a density from 0.860 g/cc to 0.905 g/cc, a melt index from 0.2 g/10 min to 50 g/10 min, and a Tm less than 125 C.

A process for welding a first molding to a second molding. The process uses an implement including first and second external surfaces. Each external surface further includes a duct. An end of the first molding is heated by a hot gas while the end is at a distance from the duct-entry plane in the range from 3 mm outside the duct to 10 mm inside the duct. A junction area of the second molding is heated by a hot gas while the junction area is at a distance from the duct-entry plane in a range from 3 mm outside the duct to 10 mm inside the duct. The heated end and the heated junction area are then brought into contact with one another and cooled, forming a weld between the first molding and the second molding. Also disclosed is a welded molding obtainable by the process of the invention.

A joint between dissimilar thermoplastic materials comprising a first thermoplastic material layer; a second thermoplastic material layer having a melting point temperature different from a melting point temperature of the first thermoplastic material layer; and an interface layer coupled between the first thermoplastic material layer and the second thermoplastic material layer; wherein the interface layer is configured to join the first thermoplastic material layer and the second thermoplastic material layer together to form the joint, wherein the interface layer comprises a melting point temperature having a value selected from the group consisting of between the melting point temperature of the first thermoplastic material layer and the melting point temperature of the second thermoplastic material layer; or lower than the melting point temperature of the first thermoplastic material layer and the melting point temperature of the second thermoplastic material layer.
