Abstract: The low resistance value resistor 11 has two electrodes 12,13 of metal strips having a high electrical conductivity. The metal strips are affixed on the resistor body by means of rolling and/or thermal diffusion bonding. A fused solder layer is formed on a surface of each electrode comprised by the metal strip. Thus, sufficient bonding strength and superior current distribution in the resistor body is obtained. Further, a portion of the resistor body is trimmed by removing a portion of the body material along a direction of current flow between the electrodes to adjust a resistance value. Thus, a precise resistor value and superior characteristics of temperature coefficient of resistance (TCR) can be obtained.

Abstract: A mounting structure for current detection resistor device has a feature that voltage detection terminal wiring is configured so as to extend along a current path in the resistor body first, and then, to bend at right angles to the current path, while maintaining electrical isolation from a resistor body of the current detection resistor device. The voltage detection terminal wiring connecting to the voltage detection terminals on the circuit board is disposed to extend for some distance in the same direction as the current path so as to cause mutual-inductance between that section of the voltage detection terminal wiring and the resistor body. This causes cancellation of induced voltage caused by the self-inductance of the resistor body, so that it is possible to nullify detection error generated by the voltage induced by the resistor body from the viewpoint of the measuring system.

Abstract: A resistor element including a cylindrical ceramic support having two openings open on longitudinally opposite end faces thereof, an electrically resistive layer formed on an outer circumferential surface, a pair of electrical conductors for connecting the electrically resistive layer to an external circuit, each of which has an end portion inserted into a corresponding one of the openings of the ceramic support, and an electrically conductive adhesive filling each opening of the ceramic support, for securing the end portion of the corresponding conductor to the ceramic support. The electrically resistive layer has two integrally formed extensions for covering the opposite end faces of the ceramic support, respectively, and respective inner wall surfaces of the openings of the ceramic support. The conductors are electrically connected to the extensions of the resistive layer by the electrically conductive adhesive filling each opening of the ceramic support.

Abstract: An electroluminescent device wherein a light-emitting layer is formed between electrode layers, and a selenium layer is formed between the light-emitting layer and at least one of the electrode layers. Each of the crystals in the selenium layer grows in a columnar shape in the direction extending at right angles to the light-emitting layer.
