摘要： A multi-range load cell weighing scale includes a load receiving pan provided at the top of a casing, a high-range load cell disposed in the casing for a high range of weight determination, and a low-range load cell disposed in the casing for a low range of weight determination in a substantially horizontally juxtaposed relation to the high-range load cell. The low-range load cell has one end connected to one end of the high-range load cell. The other end of the high-range load cell is supported on the bottom of the casing, while the other end of the low-range load cell defines a load support on which the pan is supported. The load to be weighed bears on the two load cells simultaneously. The scale enables a wide range of highly accurate weight determination, despite its use of inexpensive load cells.

摘要： A relief image scanner scans successive linear areas on an information-carrying medium such as a plastic card, illuminating each area from two different directions. The reflected light is converted to first gray-level data when the illumination is from one direction, and to second gray-level data when the illumination is from the other direction. The second gray-level data are subtracted from the first gray-level data; then the difference, and its additive inverse, are compared with a threshold to detect edges of relief patterns on the card, and pairs of edges are connected to create an accurate, distortion-free image of the relief. Additional facilities may be provided to extract edge skeletons before joining the edges, and to capture printed information by binarizing the gray-level data.

摘要： A load cell and a method of correcting the same are provided wherein a beam member on which an insulator film is formed is prevented from being trimmed by a laser beam upon laser trimming thereof. The load cell comprises a span resistor member and a zero point resistor member both formed separately of the beam member and including a span temperature correcting thin film resistor and a zero point balance temperature correcting thin film resistor, respectively, each of which has a temperature coefficient and is formed on a substrate. The resistor members are applied to the insulator film on the beam member and the thin film resistors are connected to a bridge circuit. The thin film resistors are trimmed with a laser beam to correct the span temperature correcting thin film resistor and the zero point balance temperature correcting thin film resistor for temperature. The substrates intercept a laser beam upon laser trimming of the thin film resistors.
