An improved panel jointing system wherein panels (10, 11) are provided with profiled edge portions comprising tongue formations (12) and recesses (13) which are of complementary shape to the tongues (12), the tongues (12) of one panel being receivable in the recesses (13) of another panel, wherein the profiled edge portions comprise integrally formed projections (15, 16) projecting from the edge surfaces of the tongues (12) and/or from the walls forming the recesses (13), the tongues (12), recesses (13) and projections (15, 16) being shaped and dimensioned so that, when the tongues are received in the recesses, the tongues (12) form a friction fit with the recesses (13), and the opposed facing surfaces of the tongues (12) and the walls of the recesses (13) being spaced apart so as to form a gap (18) of approximately uniform width which extends along the joint between the panels, interrupted by the projections (15, 16), the gap being fillable with adhesive.

A heavy transformer is essential to an impulse heat sealer because the heater wire is short and wide. However, when thin slits are made in the strip heater wire from the opposite sides and the strip heater wire is elongated in zigzag, the transformer can be eliminated. However, in order to use the elongated heater wire in countries using a rated voltage of 200-240V without risk, such a structure that a hand does not touch the bare heater wire semipermanently, generated heat comes out quickly on the surface and disappears is required. A ceramics thin plate of good heat conductor and electrical insulator consisting of aluminum nitride, for example, and having a thickness of 0.6 mm is placed on the heating portion of a zigzag heater wire of a metal resistor thin plate, the entire periphery is surrounded by a thermal electrical insulator such as a glass cloth while leaving the upper surface thereof, and then the whole is made to adhere and fixed onto the heat dissipation base. The good heat conductor and electrical insulator is further reinforced with a heater reinforcement, as required.

A process is for laser-welding resinous members, and includes the steps of overlapping a transparent resinous member (3) on an absorptive resinous material (4), and irradiating the transparent resinous member with a laser beam (1), thereby welding an interface between the transparent resinous member (3) and the absorptive resinous member (4) as a strip shape, wherein the energy of the laser beam (1) acting on a side of a major-curvature-radius curved part of the strip-shaped welded interface and the energy of the laser beam acting on a side of a minor-curvature-radius curved part thereof are averaged.

An improved packaging container comprising a container body (30) and a lid (40) heat-sealed to the container body is proposed which is retortable and has a high peel strength and a good easy-openability. The heat-sealed portion is formed with a groove (41) having a sectional shape gradually deepening from its outer edge (42) toward its inner edge (43), the inner edge (43) extending in a smoothly curved line while the outer edge (42) extends in a zigzag line. This ensures high peel strength against the force applied from inside of the heat-sealed portion and a good easy-openablility from outside of it.
摘要:
A stitchless seam between a first panel (4) having a functional layer and a second panel (4) having a functional layer is provided. The seam system is formed via a discontinuos fused stitchless seam (6), which connetcts a first panel to a second panel. A reinforcement (5) may be used to strengthen the discontinuos fused stitchless seam connecting the first panel to the second panel, allowing formation of a liquid- impervious stitchless seam system. A method for forming the system is also provided.
摘要:
In a method of fixing an optical member (10) to a supporting member (12), an intermediate member (11) that is heat fused upon irradiation by laser light is disposed between the optical member and the supporting member. By irradiating through the optical member onto the intermediate member, the intermediate member is heated and fused, and the optical member is fixed to the supporting member.
