| PROBLEM TO BE SOLVED: To provide a pressure sensor with improved structural temperature characteristics at low cost. SOLUTION: The pressure sensor comprises an upper electrode sheet 1 and lower electrode sheet 2 facing each other, and a spacer 3 interposed between both sheets 1, 2 in order to form a desired space between both sheets 1, 2, and those electrode sheets 1, 2 and the spacer 3 are stuck to each other through adhesives 4, 5. The upper electrode sheet 1 is formed by forming an electrode 12 on the surface of an elastic sheet-shaped base material 11 facing the lower electrode sheet 2. The lower electrode sheet 2 is formed by forming a pressure sensing electrode 22 on the surface of an elastic sheet-shaped base material 21 facing the upper electrode sheet 1. A hole 31 is opened on the spacer 3 at the position of contact part 6. A positional relation between the diameter of the hole 31, a convex part 13, and the pressure sensing electrode 22 is set up so that the peripheral part of the hole 31 locates between the convex part 13 and the pressure sensing electrode 22. At the circumference of the hole 31 at both surfaces of the spacer 3, the adhesives 4, 5 are removed and opened bigger than the diameter of the hole 31 of the spacer 3. | ||||||

| PROBLEM TO BE SOLVED: To reduce the initial contact resistance value of a membrane switch and the increasing rate thereof with the elapse of time. SOLUTION: In this switch 100, flexible printed boards 1, 2 are formed by forming conductor layers 12, 22 consisting of Ag and containing a resin polymer as a binder on base films 11, 21, and printing and forming contact parts 13, 23 formed of an alloy particle by coprecipitation of Ag and Pd and containing a resin polymer as a binder thereon so as to cover the conductor layers 12, 22. The contact parts 13, 23 are arranged opposite to each other, and a spacer 3 is arranged between them. Thus, the contact parts 13, 23 are held with a prescribed space. The composition ratio of Ag in the alloy particle, the particle size of the alloy particle and the composition ratio of the alloy particle in the contact parts 13, 23 are set to 50-97 wt.%, 0.5-5.0 μm, and 91-95 wt.%, respectively, whereby the contact resistance of the contact parts 13, 23 can be minimized to realize a current carrying of about several hundreds mA. The corrosion resistance of the contact parts 13, 23 can be enhanced by including Pd, and the increasing ratio of contact resistance by the deterioration with the lapse of time can be reduced. | ||||||
| 25 | Two-dimensional coordinate detector | JP11035782 | 1982-06-25 | JPS59726A | 1984-01-05 | HIRAISHI MASANORI |
| PURPOSE:To detect easily the position of a depressing point, by opposing partial- deposition conductor parts where a slender potential gradient layer and an insulation layer are arranged alternately to a full surface conductive layer at an interval to apply sequentially a voltage to the potential gadient layer. CONSTITUTION:A gold thin film layer is vapor-deposited on a film 2 on a substrate 1 to form a transparent condutive film. Then, the potential gradient layer comprising the partial-deposition conductor parts 3, 3', 3''... is formed into a slender rectangular shape at right angles to the face of paper by chemical etching, electrodes 4, 4', 4''... and 5, 5', 5''... are formed at both ends and the electrodes 4-4'' are grounded all together. Then, a film 7 laminated with a detecting layer 8 having electrodes 9 around the layer 8 is arranged oppositely via a spacer 6. A desired point of the film 7 is depressed while applying sequentially a voltage to the electrode 5 to measure the time when the voltage is detected from the electrode 9 and the amplitude of the voltage. Thus, the two-dimensional coordinates are obtained easily and simply. | ||||||

| An actuator body or actuator system (1) for electrical and electronic microdevices comprises at least two switch contacts (5, 7) which by way of a membrane (13) extending across at least one of said contacts can be mutually connected when the membrane is depressed for triggering a switching operation. In the actuating system described at least one of the contacts (5) is positioned in the area of the membrane perimeter and is connected via an electroconductive polymer (17) to a conductor strip (15) located on the inside surface of the membrane facing said contacts. The membrane with its conductor strip is suspended above the other contact (7) in such fashion that it and the conductor strip remain at a distance from that other contact when the system is not being operated. When depressed, the membrane can be deflected to said other contact so as to cause the conductor strip to touch that other contact, establishing the electrical connection between the two contacts (5, 7). | ||||||

| 35 | Modular touch sensitive data input device | US860287 | 1986-05-02 | US4771277A | 1988-09-13 | Peter F. Barbee; Jack L. Galloway |
| A touch sensitive data input device is provided for use with the screen of a cathode ray tube. The device has an annular bezel that loosely supports a firm clear backing plate. A rear transparent sheet element that has a coefficient of thermal expansion different from that of the backing plate is loosely retained against the backing plate to avoid deformation induced by differential thermal expansions. A closely spaced apart front transparent element is placed adjacent the rear transparent sheet, their respective adjacent surfaces having mutually orthogonal electrically conductive strips that make local electrical contact when a force is applied to the front element. An annular frame over the front element is secured to the bezel. In one aspect of the invention, a gasket with both sides coated with a resilient bonding material seals the frame to the bezel to protect the zone between the transparent front and rear elements from contamination by environmental pollutants. | ||||||
| 36 | Click disc switch assembly | US564961 | 1983-12-23 | US4539445A | 1985-09-03 | Gary D. Jabben |
| There is disclosed a click disc switch assembly comprising a plate-like base having on it electroconductive ink paths including (a) "row" paths each including a respective row of contact pads in a row-and-column matrix of such pads on the base, and (b) "column" paths corresponding to the columns of the matrix and including respective junction pads. Overlying the columns of the matrix are click disc strips secured to the rest of the assembly solely by being adhered to an overlying sheet sealing the top of the assembly. Interposed between the strips and the "row" paths is an insulating layer deposited on the base to cover portions of the row paths while leaving uncovered their junction pads. Each click disc is electrically coupled to the corresponding "column" path on the base by the coming into contact of the disc when depressed to branch segments of a further electroconductive ink path (one for each click disc strip) deposited on the insulate layer and attached through an aperture therein to the junction pad of that "column" path. Variations in the thickness of the paths on the base and on the layer are cancelled out by depositing on the base, below the click discs, pairs of bars of the same thickness as the lead portions of the paths on the base, and by raising the contact pads by an amount equal to the thickness of the paths on the layer. The base is a laminar member comprising an overlying flexible plastic sheet adhered to an underlying stiffening board. The assembly may include a tail for connecting it to other circuitry. | ||||||

| 39 | Precious metal switch contact component and its preparation method | US14896403 | 2014-09-15 | US10026564B2 | 2018-07-17 | Huisheng Han; Hongmei Zhang; Yang Ding; Zhihong Dong; Cheng Huang |
| This invention discloses a preparation method for precious metal switching contact components by means of plating masking, plating and etching processes. The plating masking process is performed by using a plating mask ink with or without a photo exposure machine. Plating of precious metals is performed by electroless plating or electro plating methods. Etching is carried out with etching solutions containing weak organic acids, weak inorganic acids or acidic buffering agents. Improvement of the etched surface gloss and prevention of the side etching are realized with the sulfur-contained compounds. The dust- and oil stain-resistances of the switch contacts are improved by increasing the etching depth. The switch contacts made by this invention are featured with the advantages of good reliability, good resistance to dust and oil stain, short contact bounce time, long service life, low cost of raw materials and so on. | ||||||
