An insert for load application and/or anchorage of various components into/onto a composite sandwich panel. The insert includes a rotationally symmetric inner insert ring, an outer insert ring, an insert connecting portion connecting the inner insert ring with the outer insert ring, and an insert trench provided between the outer insert ring and the inner insert ring.

A method for manufacturing a metal-clad laminate sheet including forming a laminate sheet having the thermoplastic liquid crystal polymer film and the metal foil bonded together; and providing the laminate sheet with a heat treatment which satisfies conditions (1) and (2) below: (1) a heat treatment temperature ranges between 1 C. inclusive and 50 C. exclusive higher than a melting point of the thermoplastic liquid crystal polymer film. (2) a time for the heat treatment ranges from one second to 10 minutes.

A device (10) comprising a carrier material (14) and a matrix material (12) deposited onto the carrier material in a pattern that leaves a predetermined amount of space (18) between each deposition of matrix material.

There is provided an exposing device which includes an elongated optical head in which a plurality of light emitting portions are arranged, and a supporting member to which the optical head is adhered. The optical head and the supporting member are adhered by a first adhesive, and a second adhesive of which a modulus of elasticity after curing is lower than that of the first adhesive. The second adhesive is applied in a second adhesive area which is located at a boundary between the optical head and the supporting member and which is longer, in a longitudinal direction of the optical head, than a first adhesive area which is located at the boundary and to which the first adhesive is applied.

The present invention is a method for seaming a polymeric material. The method involves forming an interface between a plurality of separate polymeric sheets of materials. Next, heat and pressure are applied to facilitate the diffusion of the polymer molecules at the interface. A diffusion weld is made when the polymer molecules diffuse across the interface.

There is provided a technique to strongly integrate a galvanized steel sheet and a resin molded article. A hot-dip galvanized steel sheet is immersed in an aqueous solution for aluminum degreasing to form a specific roughness on the surface. The surface is covered with convex protrusions having a diameter of about 100 nm, and a chromate treatment layer appears in the surface. A resin composition comprising 70 to 97 wt % of polyphenylene sulfide and 3 to 30 wt % of a polyolefin resin is injected onto the surface. The resin composition penetrates into ultra-fine irregularities and is cured in that state, and thereby a composite in which the galvanized steel sheet and the resin molded article are strongly integrated can be obtained. The shear rupture strength of the composite is extremely high.

A method producing thermoplastic liquid crystal polymer (TLCP) film(s) may include (i) preparing a TLCP film (adherend film) and a TLCP film (adhesive film); (ii) examining each TLCP film for relative intensity calculated as a ratio in percentage of a sum of peak areas of CO bond peak and COO bond peak based on the total area of C1s peaks in the X-ray photoelectron spectroscopy (XPS) profile to calculate relative intensity X (%) for the adherend film and relative intensity Y (%) for the adhesive film; and (iii) controlling the TLCP film adhesive film to have a relative intensity Y by selection or activation treatment of the adhesive film so that the relative intensity X of the adherend film and the relative intensity Y of the adhesive film satisfy
38X+Y65(1), and
8.0YX8.0(2).

A heater for a cigarette-like electronic cigarette and a method of manufacturing the heater are provided. The heater is provided with a heat transfer efficiency improved by strengthening a bonding force between a cigarette support portion and a heater portion by thermally pressing and bonding the cigarette support portion and the heater portion together using a heat-dissipating adhesive layer with a heat-dissipating filler added to a high-heat-resistant thermoplastic polyimide resin.
