Abstract: An electromechanical module with pressed electrical connections includes the following components: 1) a printed circuit board having a first array of I/O pads; 2) a substrate having a second array of I/O pads that are aligned with and face the first array of I/O pads; 3) compressible electrical contacts which lie between the first and second array of I/O pads; 4) a thin springy plate having a central section which presses against the printed circuit board in line with the first array of I/O pads, and having a springy periphery that extends in a quiescent state away; from the printed circuit board; and 5) a compressing means which compresses the electrical contacts by forcing the substrate towards the printed circuit board while bending the springy periphery of the thin-springy plate towards the substrate. When the plate is in a state where the electrical contacts are fully compressed, the thin-springy plate is relatively flat; and thus, the module has a low profile.

Abstract: Slack in the engagement of a shaft 5 and a rotor 3 in a case 1 is prevented by the resiliency of an O ring 6 under radial but not axial compression. Even if heat stress is added, the variable resistor which can secure air-tightness is provided. The rotor 3 and a slider 4 are accommodated in the case 1. A resistance substrate 2 having a collector electrode 25 formed on the central portion of the surface and a circular resistor 24 formed concentrically on the periphery of the collector electrode 25 is engaged with the lower end part of the case 1. A stepped surface 12 supporting the peripheral surface and the bottom surface of the O ring 6 is formed on the upper surface of the case. A boss portion 55 contacting the inner circumference of the O ring 6 and an operating portion 51 projecting on the upper surface of the case 1 and covering the stepped surface 12 is formed on the shaft 5.

Abstract: A sensor is disclosed that fits in a compact package. This compact sensor is ideal for sensing rotary positions and for accommodating one or more potentiometers. The resistor track is parallel and opposed to the collector track, and the wiper is placed between the two tracks to swipe both of them in one embodiment. This allows a short package, because the tracks are opposed to each other rather than being in a line, and a narrow package, because the tracks are not placed side by side. Another advantage of the invention is that putting the resistor track on a larger radius and the collector track on a smaller radius allows the resistor track to be longer. Having a longer resistor track allows a higher resolution, yet a package containing the potentiometer will still be relatively small. Several potentiometers may be placed in the sensor to provide redundancy yet retain compactness.

Abstract: A chip thermistor is produced by providing a planar rectangular thermistor block with a pair of electrodes formed on its surfaces, each of the electrode being formed so as to be in part on a different one of the main surfaces and extending continuously at least onto one of the side surfaces. The thermistor block thus prepared is cut transversely to obtain a plurality of thermistor elements. A specified number of these thermistor elements are then aligned and stacked one on top of another with their main surfaces facing each other. A layer of an insulating material such as glass with thickness greater than 10 .mu.m is inserted between each mutually adjacently stacked pair of these thermistor elements. Outer electrodes are formed on the outer surfaces of the stacked structure so as to electrically connect to the electrodes on the stacked thermistor elements on their aligned end surfaces.

Abstract: A position sensor, in particular, a modular position sensor for easy coupling to another modular device, like a gas pedal of a vehicle. The sensor eliminates the use of permanently attached electrical leads or pins attached to, for example, the output pads on flexible film coupled to a rotor. The sensor is provided with a housing wall having slots therein, conductive elements, a flexible film, and a pressure wall. In the preferred embodiment, the sensor is mounted on an external device having pins or electrical leads. The pins protrude through the slots in the housing wall and the contact conductive elements that are in direct contact with the output pads on the flexible film.

Abstract: A resistor card for a potentiometer to measure the fuel in a fuel tank consists of a non-conductive substrate with a plurality of elongate conductive contacts deposited. The contacts have an elevation above the surface of the substrate and the contacts are oriented in parallel relationship to each other to form a wiper track across which a wiper is movable. To reduce the rate at which the upper surfaces of the contacts are worn away by movement of the wiper, a non-conductive filler is deposited between the conductive materials which form the lands.

Abstract: A positive temperature coefficient (PTC) thermistor device for improving workability during assembly of a PTC thermistor element in a casing while eliminating risk of damaging electrode surfaces with enhanced element position stability. To this end, the casing is provided with an insulating guide section for guiding the PTC thermistor element at or near one end, causing the PTC thermistor element to be elastically held by first and second terminals both at a position on one electrode surface which position is near the other edge of the PTC thermistor element and at a position centrally placed on the remaining electrode surface. The guide section essentially consists of first and second guide sections which oppose each other with the PTC thermistor element being sandwiched between, allowing PTC thermistor element to be held by either one of the first and second guide sections and by the first and second terminals.

Abstract: A first rotor and a second rotor are prepared. The first rotor has a resistor and inner-peripheral and outer-peripheral electrodes respectively connected to end portions of this resistor. The second rotor has a resistor and inner-peripheral and outer-peripheral electrodes symmetrical with those of the first rotor, provided at a position corresponding to that obtained by rotating the first rotor about the axis of the first rotor by an angle of 180.degree. with respect to the first rotor. A variable resistor selectively uses either one of the first rotor and second rotor. This makes it possible to provide a variable resistor which requires few parts. Also, this makes it possible to reduce the kinds of bending operations that must be performed on the terminals.

A pair of membrane potentiometer are interposed between the cover and the backplate to receive a first voltage, and output a second voltage that is a percentage of the first voltage. A pair of magnet assemblies are located on outer surfaces of the membrane potentiometer to generate a magnetic repulsion force to keep the membrane potentiometer separated from each other.

Abstract: An electrical resistor has a surface mounted four terminal current sensor of a very low resistance value and capable of handling short pulses of high power. It comprises a flat metal late, 1 to 50 mils thick, of an alloy of high electrical resistivity, to which are welded, on two opposite sides, two flat metal plates of very high electrical conductivity which serve as terminations for electrical interconnection. A slot is cut, from the outside edge toward the center, into each of the two termination plates which divides them into a wide pad for connection of current carrying wires and a narrow one for voltage sensing. The depth of the slots is optimized to get the best stability of resistance readings with changing ambient temperature and under influence of the self-heating effect.
