A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.

A production method of a modeled object includes a fixing step of fixing a thermally expandable sheet onto a tray by entirely or partially fixing a periphery of the thermally expandable sheet placed on the tray by a fixing member; a thermally expanding step of thermally expanding partially the thermally expandable sheet, which is in a state of being fixed onto the tray by the fixing step, by being heated by irradiating the thermally expandable sheet with light by an irradiation unit, while moving the irradiation unit from a first position toward a second position unit; and cooling the thermally expandable sheet, which has been thermally expanded partially by the thermally expanding step, while maintaining the state in which the thermally expandable sheet is fixed onto the tray, while returning the irradiation unit from the second position to the first position.

It is disclosed a process and an apparatus for manufacturing a figure of eight cable. An extrusion head has separate extrusion dies extruding in parallel a first and second outer sheath around a first and second core, respectively, so as to provide two separate cable elements having respective longitudinal axes laying in a first plane. While the outer sheaths are in a softened state, the cable elements are passed in parallel through a twisting die which causes their longitudinal axes to lay in a second plane forming a predetermined twisting angle with respect to the first plane. This twisting causes the outer sheaths to join together, thereby forming a figure of eight cable.

A curable adhesive that is particularly well suited for use in an injection or compression molding operation. The adhesive is based on polymeric resins having carboxylic acid and acrylate ester functionality, such as grafted phenoxy resin, and further constituents such as organic carbonates, blocked isocyanates, catalysts, maleimide compounds, hydride sources, and a carrier fluid. The curable adhesives are particularly well suited for bonding liquid injectable substrates such as liquid silicone rubber, or polyamides to rigid substrates, such as aluminum, stainless steel, or glass.

[Problem] The objective of the present invention is to provide a resin sheet that has a favorable tactile sensation and no less than a certain light transmittance and a molded article thereof.

[Solution] A resin sheet that has hair-like bodies arranged regularly on at least one surface of an underlayer and in which a continuous phase is formed without any structural boundary between the underlayer and the hair-like bodies, wherein the average height of the hair-like bodies is no less than 30 μm and no greater than 500 μm, the total light transmittance of the resin sheet measured in accordance with JIS K 7136-1 is no less than 0.1% and no greater than 20%, and the contrast ratio of the resin sheet measured in accordance with JIS K 5600 4-1 is no less than 70% and no greater than 98%.
