Abstract: It is a method for producing an electrode material containing Cu, Cr and a heat-resistant element. A heat-resistant element powder and a Cr powder are mixed together in a ratio such that the heat-resistant element is less than the Cr by weight. A mixed powder of the heat-resistant element powder and the Cr powder is baked. A sintered body obtained by the baking and containing a solid solution of the heat-resistant element and the Cr is pulverized, and a solid solution powder obtained by the pulverizing is classified, to have a particle size of 200 μm or less. 10-60 parts by weight of the classified solid solution powder and 90-40 parts by weight of a Cu powder are mixed together, followed by sintering to obtain the electrode material. If a low melting metal powder having a median size of 5-40 μm is mixed with a mixed powder of the solid solution powder and the Cu powder, the deposition resistance property is further improved.

Abstract: In a conductive sheet using a metal nanofiber, metal migration in a visible conductive pattern is eliminated. Also, the intervals of the conductive portion (separate sheet terminal) are shortened. On a substrate (26) is a conductive sheet (10), formed from a transparent conductive pattern (11) and a visible conductive pattern (16). The transparent conductive pattern comprises a first nanofiber layer (12) that is a layer including a metal nanofiber, and a first heat-insulating layer (29) adjacent to the first nanofiber layer. The visible conductive pattern (16) forms an underlayer pattern from a second nanofiber layer (17) that is a layer including a metal nanofiber, and a second heat-insulating layer (27) adjacent to the second nanofiber layer; and a top-layer pattern comprising a paste layer (18) that is a layer including a metal paste laminated on the underlayer pattern. The second heat-insulating layer (27) is a conductive sheet that is a layer including a metal nanofiber cut to a minimum size. The visible conductive pattern (16) forms a water-shielding layer (21) on the underlayer pattern, and forms the top-layer pattern on the water-shielding layer.

Abstract: A contact element for the intermittent contacting of conductor tracks on a circuit board, in particular, for flexible touchpads, for example for flexible input devices in the automobile industry, is made from a metal foam. The metal foam may be at least partly infiltrated by an elastomeric material which can also be the material of construction of the touchpad. The contact element has a very reliable construction which is particularly suitable for high voltage application. A method for production of the contact element, touchpads/input devices with such contact pads and the use of the contact pads is also provided.

Abstract: An electronic keyboard includes a base defining a surface having a plurality of faces oriented at different angles. A flexible printed circuit defining rows of switches is disposed on the base surface and rows of switch actuators are disposed on the printed circuit. The actuators comprise key guide strips which define key positions offset along the rows from the switch positions and spring strips which bridge the key and switch positions so that, when keys slidably mounted in the key guide strips are depressed, they close the associated switches. The spring strips are designed to produce minimum operator fatigue and all of the keyboard components coact to give the keyboard a very low profile.
