Abstract: The invention relates to touch panels for use in a variety of electronic apparatuses, and designed to prevent separation of a lower substrate and an antireflection layer, and to ensure reliable operation. An undercoat layer (9) made of any of silicon oxide and a compound having a principal ingredient of silicon oxide is disposed between the antireflection layer (5) and the lower substrate (2) made of glass having the same principal ingredient of silicon oxide, to improve strength of adhesion between the lower substrate (2) and the antireflection layer (5), thereby preventing separation of the antireflection layer (5) from the lower substrate (5), and providing the touch panel with reliable operation.

Abstract: The invention presents a touch panel disposed at the display screen side of a liquid crystal display device or the like, and excellent in surface smoothness and environmental resistance. In marginal outer circumferential part 400B for adhering and fixing first transparent substrate 21 and second transparent substrate 31 face to face, insulating layer 27 for correction of step difference is disposed in order to make uniform the film thickness. Adhesive layer 29 is disposed on insulating layer 27, and first transparent substrate 21 and second transparent substrate 31 are adhered to each other. As a result, the adhesion fixing state if stabilized, and the adhesion strength is enhanced, and a touch panel suitable for car-mount unit excellent in surface smoothness and environmental resistance can be presented.

Abstract: Disclosed are a compact input device that offers a wide space for input operation and portable equipment using the device. The input operation section of the input device is not only for data entry by users, but also for transmitting sound vibration. The coupling section of the device is coupled to the input operation section to form a closed cavity between the two sections. The sound vibration transmitting section, which is formed adjacent to the closed cavity, conveys sound vibration, via the closed cavity, from the input operation section to the sound vibration transmitting section (or vice versa). The portable equipment includes the aforementioned input device and a sound vibration element. In the equipment, the sound vibration element is coupled to the sound vibration transmitting section of the input device. Sound vibration is transmitted, via the closed cavity and sound vibration transmitting section of the input device, from input operation section to the vibration element (or vice versa).

Abstract: An easy-to-assemble and inexpensive TTP used in various electronic apparatus for switching the operation. A method for manufacturing the TTP is also disclosed. Lower substrate 25 is provided with a pair of connection electrodes 29 and 30 opposing to upper lead-out sections 23A and 24A; one end of which connection electrodes, or the left connection parts 29A, 30A, are glued and connected to upper lead-out sections 23A, 24A, while the other end, or the right connection parts 29B, 30B and lower lead-out sections 27A, 28A are glued and connected to wiring patterns 32, 33, 34 and 35 to implement a finished TTP.

Abstract: A touch panel includes an upper substrate having an upper electrode thereon, a lower substrate having a lower electrode thereon, and a spacer for bonding the substrates to each other. The spacer contains bubbles and has an elastic property. The touch panel has small dimensions while having a desired effective size of its operable area.

Abstract: An inexpensive touch panel securing a predetermined active area and yet being downsized is provided. The touch panel includes an upper substrate having an upper conductive layer beneath its lower face, and a lower substrate having a lower conductive layer on its upper face opposite to the upper conductive layer at a given interval. Pressing and heating a adhesive layer made from thermoplastic resin and hardener allows bonding the upper and lower substrates together. The touch panel is thus constructed.

Abstract: A seat sensor includes a top sheet made of insulating film; an upper insulating layer with insulating particles partially protruding from the surface of the upper insulating layer; and an upper resistor layer formed over the upper insulating layer. The seat sensor further includes a bottom sheet made of insulating resin film disposed under the top sheet; a lower insulating layer with insulating particles partially protruding from the surface of the lower insulating layer; a lower resistor layer formed over the lower insulating layer, and an insulating spacer layer formed between the top sheet and the bottom sheet. The above construction provides a seat sensor that has stable resistance properties even after repeated loading and a detection device using the seat sensor.
