| 122 | Keypad and method of separating a crosslinked cured resin layer thereof | US10317237 | 2002-12-10 | US20030107554A1 | 2003-06-12 | Seiko Motegi |
| The present invention related a keypad (1) in which a keypad main body (4) composed of a thermoplastic elastomer has formed thereon a cross-linked cured resin layer (5) of a cross-linked cured resin that is separable from the keypad main body (4) by swelling with a predetermined solvent, or a method of separating the keypad main body (4) and the cross-linked cured resin layer (5). The keypad main body (4) is made of a thermoplastic elastomer and has the cross-linkage curing resin layer (5) placed thereon, which eliminates defects of a display layer (6) placed on the thermoplastic elastomer surface exhibiting low abrasion resistant properties and the display layer readily disappearing and which not only renders the display layer (6) to hardly disappear even if a key is repeatedly used, but also allows the cross-linked cured resin layer (5) to readily separate from the keypad main body (4) when the resin layer (5) is swelled with a solvent, thereby making it possible to individually and readily recycle the cross-linked cured resin layer (5) and the keypad main body (4) and to obtain a recycled article of high quality. | ||||||

| 139 | Transparent touch panel switch | US57274 | 1987-06-01 | US4786767A | 1988-11-22 | Bruce Kuhlman |
| An improved transparent touch panel membrane switch for use and shielding in front of a visual display terminal is disclosed. The switch is made up of a plurality of plastic sheets arrayed substantially parallel to one another in a sandwich configuration. The outermost of the sheets has an antireflective hardcoat. Two adjacent but spaced apart inner sheets provide the electrical contact through transparent low reflectance conductive metal coatings. The switch additionally contains a further inner antireflective transparent electrically conductive coating which provides shielding against the passage of electromagnetic and radio frequency interference through the membrane switch. The layers in this switch all contribute to a relatively low transmittance of back lighting from the visual display terminal but also significantly reduce reflectance such that the overall signal-to-noise ratio is substantially enhanced. | ||||||
