  • Publication number: 20200340850
    Abstract: Avoiding the discharge of lightweight articles as much as possible while improving the yield. A combination weighing device (1) comprises: a transport unit (10, 11) configured to transport an article (100) supplied from an outside; a plurality of hoppers (13) configured to perform a measurement while temporarily holding the article (100) transported by the transport unit (10, 11) to acquire a mass value of the article (100); and a controller (5) configured to select a combination of the hoppers (13) to discharge the article (100) from the hopper (13) included in the selected combination based on a target mass value set in advance and the mass value acquired in each of the plurality of hoppers (13). The target mass value is a value obtained by adding a correction value to a mass value requested by a user, and the correction value is set to a different value depending on a number of the hoppers (13) used for the combination.

  • Patent number: 9698746
    Abstract: An object of the present invention is to realize a loop through circuit, in an active connector, securely having a preferable mismatching attenuation characteristic and having a preferable signal transmission characteristic, with respect to an input port, an output port, and an internal port, without providing a special circuit outside the connector. A connector base part has the input port inputting an external signal, the output port outputting a loop through signal, and the internal port outputting a signal into a device. First and second matching circuits, an equalizer circuit, a dividing circuit, and a driving circuit are stored in the connector base part. The matching circuit is supplied with an external signal input from the input port. The dividing circuit divides a signal to be input to generate first and second divided signals, and outputs them to the internal port and the output port. The equalizer circuit compensates for a frequency characteristic and/or loss of a signal to be input.
