摘要： A load cell wherein strain gauges are produced by a thin film process on a pattern forming surface of a strain- • inducible element in such a manner that the resistances of the strain gauges are varied in accordance with deformations caused in thin portions of the strain-inducible element, and adjustable resistors are deposited by the thin film process for an electric circuit assembly including a differential amplifier, a potential divider, a signal amplifier and a zero-point setter. And each of the resistors is adjusted by trimming simultaneously with trimming adjustment of the strain gauges.

摘要： A load cell weighing device has a plurality of load cells (1a-1d). In the device, detection values are respectively output from the load cells (1a-1d). The detection values are digitized by analog-to-digital conversion circuits (3a-3d). Low frequency noise components involved in the digitized detection values are reduced by digital filters (21a-21d). Then, the noise-reduced values are summed to provide weight data.

摘要： The invention provides an electronic appliance wherein a detection output of a sensor means is not influenced by a high frequency component originating in external radio waves. The electronic appliance comprises a conductor member located in a spaced relationship by a predetermined distance from a base which constitutes a body case together with a housing. A by-pass route is provided for by-passing a sensor means near the conductor member to introduce a high frequency component of electric current flow induced in the conductor member to the base. A distributed capacitance forming means is interposed in the by-pass route. Thus, a high frequency component of electric current flow induced in the conductor member is released to the body case via the by-pass route.
