Abstract: A resistor component is provided, including a ceramic bar having a film applied thereon, a protection layer formed on the film in a middle portion of the ceramic bar, an end plating layer formed on the film at two ends of the ceramic bar, an insulation layer formed on the protection layer, and a color coded marking formed on the insulation layer that indicates the resistance of the resistor component. The end plating layer is formed by a barrel plating method and includes copper, tin, nickel and a combination thereof. The resistor component thus has a low cost and is manufactured by a simple process, simultaneously avoids the occurrence of pores or incompletely sealed join that may be caused by the prior method. Therefore the resistor component has high reliability.

Abstract: A touch panel apparatus includes a liquid crystal display device including a liquid crystal section, an illuminating section disposed at a rear side of the liquid crystal section for illuminating the liquid crystal section, and a frame section disposed on an outer periphery of the liquid crystal section; a transparent resistive membrane type of touch panel disposed at a front side of the liquid crystal display device; and a spacer member disposed between the frame section of the liquid crystal display device and a periphery of the touch panel for defining a clearance between the liquid crystal section of the liquid crystal display device and the touch panel. The spacer member covers an area from a front surface of the frame section of the liquid crystal display device to a periphery of a front surface of the liquid crystal section while maintaining the clearance between the liquid crystal section and the liquid crystal display device.

Abstract: A method of measuring the temperature of a wire which is surrounded by a layer of insulation includes the step of wrapping the layer of insulation with an electrically and thermally conductive ground shield having two opposing longitudinal ends, one of the ends being electrically grounded. A first relationship is determined between the temperature of the wire and a temperature of the shield. A second relationship is ascertained between an electrical resistance of the shield between the longitudinal ends and the temperature of the shield. The electrical resistance of the shield between the longitudinal ends is measured. The temperature of the wire is established by using the first relationship and the second relationship to correlate the measured electrical resistance of the shield to the temperature of the wire.

Abstract: An accurate, setting-protected, temperature controlled soldering iron has a control circuit including a non-adjustable replaceable resistor mounted near the junction of the handle and the tube which holds the soldering tip. When it is desired to change the temperature of the soldering tip, the handle must be disassembled from the tube to replace the non-adjustable resistor. Very accurate control of temperature at the soldering tip is maintained by the utilization of different laser trimmed resistors having extremely accurate resistances. A window is provided in the soldering handle to observe a number associated with the value of the non-adjustable replaceable resistor.

Abstract: A chip resistor comprising a cuboid resistor body of a ceramic material and solderable, metal, current-supply strips at a first pair of opposing side faces of the resistor body, can readily and accurately be manufactured in that a second pair of opposing side faces of the resistor body is covered completely with electrically insulating layers and in that the metal strips around the edges of the resistor body in such a way that the electrically insulating layers are partly covered by the metal strips.

Abstract: A potentiometer includes a conductive member and a resistive member both enclosed in a flexible fluid-filled bag so that depression of a point on the bag causes the conductive member to touch a point on the resistive member. Latching means are provided to latch the bag in its depressed position at any point and two forms of visual indication are provided for displaying the resistance values selected.

Abstract: An elongated tape fabricated of an electrically insulative material has a pair of strips which run therealong, these two strips being joined together at one end thereof but not at the other, to form an open loop. The strips are fabricated of an electrically conductive material having a relatively high resistivity. The opposite ends of the tape are each wound on a separate reel, the tape being fed from one reel to the other by means of a drive mechanism. The tape is marked along its length with indicia representing resistances between the two strips for each position of the tape between the two reels. A window with a marker is provided to read out these resistances. A pair of electrical wipers are mounted in contact with the pair of strips to connect the strips to a circuit or the like, in which the resistance is to be utilized.
