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： 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.
