Patent TW-217995-B (TW)
IPC: B29C55/06
Filed: 1992-02-17
Granted: 1993-12-21
Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material is formed of at least two plies of material which are either intermittently or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies is stretchable and elastomeric, while the second ply is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration. This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretching. In a particularly preferred embodiment of the present invention, the mechanical stretching operation is carried out by passing said laminate web between multiple pairs of meshing corrugated rolls, each pair of rolls exhibiting a greater degree of meshing than the preceding pair, to sequentially stretch said web in stages. Sequentially stretching the web in the foregoing manner minimizes damage to the web.

Title: Asynchronous self-adjusting input circuit
Inventor: Jeffrey p wright
IPC: H03K19/02
Filed: 1995-12-28
Granted: 1996-06-21
Abstract: An asynchronous self-adjusting circuit includes an input circuit receiving an input signal and providing an output signal. The input circuit starts to switch the output signal to a first logic level based on the level of the input signal reaching a falling edge adjustable trip point, and starts to switch the output signal to a second logic level based on the level of the input signal reaching a rising edge adjustable trip point. A control circuit dynamically and asynchronously adjusts the falling and rising edge adjustable trip points as a function of a previous value of the input signal to permit the asynchronous self-adjusting circuit to respond quickly to changes in the input signal without causing oscillation of the output signal by asynchronously controlling when the output signal is permitted to again switch logic states once the output signal switches logic states.

Title: Excellent vivid reflectivity resin-coated metal sheet with excellent workable adhesion strength
Inventor: SUGIMOTO YOSHIYUKI
IPC: B32B15/08
Filed: 1996-01-18
Granted: 2000-09-11
Abstract: In a resin-coated metal sheet, at least one surface of a metal sheet 10 as a base is overlaid by a transparent polyseter resin film A of 5 to 100 mu m thickness, through a paint layer E, a modified olefin resin layer D of 5 to 100 mu m thickness, a pattern or/and solid printing layer C and an adhesive layer B which layers are put one over another in order from side of the metal sheet toward the transparent polyseter resin film. Since the modified olefin resin layer which is provided in between the transparent polyseter resin film and the metal sheet has the excellent adhesiveness against the printing layer, the paint layer and the polyseter resin film, even if the resin-coated metal sheet is formed under the severe condition against the resin-coated metal sheet, for instance by deep drawing, delamination does not occur so that the excellent workable adhesion strength is shown. Further, the roughness of the surface of the metal sheet, and unevenness of several component resin layers are absorbed by a modified olefin resin layer so that the excellent vivid reflectivity for a resin-coated metal sheet can be obtained.
