Abstract: The present invention provides a foamed member capable of inhibiting or preventing foam breakage at the time when the foam member is peeled from a carrier tape, even when the foamed member has a high expansion ratio. The foamed member has a thermoplastic resin foam layer containing a thermoplastic resin foam formed through a step of impregnating a high-pressure inert gas into a thermoplastic resin and subsequently reducing pressure, and at least one of a thermoplastic polyester-based resin layer and a thermoplastic elastomer resin layer disposed on at least one side of the thermoplastic resin foam layer.

Abstract: [Problem to be Solved] When a wood raw material is heat-pressed in order to produce a woody material or woody board, steam is generated in an interior of the wood raw material. The heat-pressed wood raw material is then decompressed with the steam staying in the interior of the wood raw material. This causes a puncture or a rupture of the woody material. The puncture occurs in the last phase of the production process, thus spoiling the entire production process. In order to avoid the puncture, the wood raw material needs to be dried completely. This requires a large amount of energy.

Abstract: A method of continuously forming heated conduit includes performing a tape for winding onto a spiral pipeline former. At least one conductor is positioned adjacent to the centerline of and parallel with a thin polymer ribbon. The ribbon is folded in half to encapsulate the conductors. The folded ribbon is thermally welded to itself. The folded, welded, ribbon is passed through a creaser, which forms a crease midway across the folded ribbon. The creased pre-formed ribbon is formed into a conduit in a continuous process on a spiral pipeline former.

Abstract: The invention provides a working trough and a method for maintaining a uniform temperature of a working fluid. The working trough is applied to an electrical discharge machine that performs wire cutting using the working fluid. The method for maintaining a uniform temperature of the working fluid is applied to the working trough and characterized by forming opening structures in a receiving slot of the working trough such that a spiral swirl having a predetermined height is allowed to be formed in the working fluid, thereby maintaining a uniform temperature of the working fluid in the receiving slot when a wire cutting process is performed in the working fluid by the electrical discharge machine. The disturbance of the spiral swirl also facilitates the discharge of scraps. The present invention further has an advantage of low cost.

At least one of the deformable plates is fixed in a mobile manner to a support structure for opening or closing the pressing device around at least one shaped support which is provided with transport means to and from the pressing device and is suitable for supporting the semimanufactured product during the pressing with at least one waterproofing sheath.

Abstract: For manufacturing ophthalmic lenses and other optical form bodies made of plastic material, plastic form parts are used which are made by non-cutting shaping and are then further worked by mechanical production steps. Said plastic form parts are circular blanks (1) made of two different plastic materials which are firmly joined to each other. Thereby, an interior lens element (2) that consists of a high-quality material is concentrically surrounded by a ring fixture (3) which consists of a low priced material. Either surface of the lens element (2) may feature any given geometry. During mechanical working, the ring fixture (3) is used for mounting as well as for depositing and, in addition, for stabilizing the workpiece (9). For this reason it is partially maintained throughout the mechanical working and is cut off at the end only.

Abstract: A skin adhesion apparatus includes an upper mold half and a lower mold half. The upper mold half and the lower mold half clamps a core material and a skin laid on the core material so that the skin is adhered to a surface of the core material. Disposed along a mold surface of the upper mold half is a tubular member made of elastic material. The skin adhesion apparatus also includes a pump for supplying fluid into the tubular member. When adhering the skin to the core material, the upper mold half is pulled down and then stopped at a predetermined distance above the core material. After then, fluid is supplied into the tubular member so that the fluid pressure inflates the tubular member.
