Abstract:
An object is to provide a gas container and a method of producing the gas container in which liner constituting members can appropriately be joined to each other and productivity can be improved. A gas container has a resin liner constituted by joining a plurality of liner constituting members, the liner constituting members each having at least a hollow cylindrical part, and a reinforcement layer arranged on an outer periphery of the resin liner. Joining portions of the liner constituting members are joined to each other over a circumferential direction by laser welding, and the joining portions are made of a laser transmitting resin and a laser absorbing resin, respectively.
Abstract:
A laser welding method and apparatus especially suitable for laser welding polymer articles having low light transmissivity at the wavelength used for laser welding. A protective region is provided to the articles being welded that is designed to protect the irradiated surface from degrading during welding.
Abstract:
A low cost method and apparatus for simultaneous block melting of a material by laser enabling completion of work in a short time. A laser beam from a YAG laser source etc. strikes a diffraction type optical element like a diffraction lens and is split into a large number of beams by diffraction and transmission. The beams are focused by a condensing lens etc. on a plastic surface as a large number of points or a line. The plastic is simultaneously heated to melt at these focused points for welding with another object or for removal. Therefore, no deformation occurs in the worked material like in the prior art where a surface was scanned by a focused point. The worked material may be a metal etc. in addition to a plastic.
Abstract:
A system for sealing a packaging wrapper around an object directs a flow of heated air to end flaps of the wrapper to move the end flaps into sealing contact with a body section of the wrapper to substantially enclose the object. The system includes an oven, a conveyor, a source of heated air and a means for deflecting the flow of heated air to the conveyor to seal end flaps of the wrapper with a body section of the wrapper. In use, an object surrounded by the wrapper body section is moved through the oven on a conveying surface of the conveyor, and heated air is moved through the oven bypassing the conveying surface to a region below the conveying surface. The heated air flow then encounters the means for deflecting the heated air flow, which directs the air flow upward and through the conveying surface to impact and move the end flaps into sealing contact with the wrapper body section.
Abstract:
A method for encapsulating a cellulose based substrate with polymeric films involves heating the respective films using a non-electrogmagnetic radiation heating source and providing a pressure differential between an environment defined between the films and an environment external to the films so that conformance of the film to the cellulose based substrate is promoted. The cellulose based substrate is entirely encapsulated by the films and the films are sealed around the peripheral edges of the container as well as edges that are defined adjacent slots and cutouts.
Abstract:
A method of affixing a gasket to a transparent substrate utilizing a fixture having a channel formed therein, into which the gasket is inserted and held in place by, for example, a vacuum. Alternatively, a removable form may be inserted into the channel, and the elastomeric member/gasket is inserted into the removable form. A suitable substrate is precisely positioned on the fixture in a predetermined position relative to the elastomeric member. An adhesion promoting primer may be applied to the substrate, and an adhesive may be applied to the gasket, or to the substrate. The elastomeric member is then bonded to the transparent substrate. Finally, the completed assembly is removed from the fixture.
Abstract:
In a film lamination method of the present invention, sound waves with a predetermined frequency are applied to at least one of a substrate or a film disposed on the substrate. Thus, by means of an acoustic vibration energy action, the adhesion of the film to the substrate and the quality of covering irregularities can be sufficiently enhanced and the embedding quality of the film to the irregular portions of the substrate can be achieved to a high standard.
Abstract:
A fabric light control window covering in which fabric vanes are adhesively bonded between two sheer fabric sheets such that relative movement between the sheer fabric sheets in a direction perpendicular to the longitudinal direction of the fabric vanes changes the angle of the fabric vanes and, thus, controls the amount of light admitted through the shade. The vanes are bonded to the sheer fabric sheets in a manner which tends to bias the sheer fabric sheets together to the nonlight admitting position. Also, disclosed are methods and apparatus for manufacturing the above window covering. The method features linear application of adhesive to the vane material which provides for a uniform appearance in the finished product. A heat setting process and apparatus is disclosed in which the bonded layers of sheer fabrics and vanes are fed between belts over hot and cool surfaces, under uniform tension and pressure. This provides for heat setting of the layers of the window covering to a uniform temperature-size relationship without inducing wrinkles or distortion into the fabric during heat setting.
Abstract:
A thin film bonding method for bonding a thin film to an target surface by using an adhesive agent includes the steps of: applying the adhesive agent on the target surface and mounting the thin film on the adhesive agent; applying a a fluid pressure on the target surface and the thin film from a central portion to an circumference according to lapse of time, so as to allow the thin film and the target surface to be bonded partially; and hardening the adhesive agent. The compressive force using the fluid having a magnetic force in the thin film bonding proceeds in a spiral form from the central portion to the circumference of the disk according to lapse of time, so that the air trap existing in the adhesive agent can be effectively removed, and thus, the flatness of the disk can be prevented from degradation due to the air trap.
