Abstract: A detection device is retained in the rumen of a cow by being orally administered to the cow, and detects the state of the inside of the rumen. The detection device wirelessly transmits measured values of the rumen pH as detection results. A monitoring unit (receiver and monitoring server) acquires information transmitted from the detection device, and monitors the state of the inside of the rumen. The detection device is configured to be recoverable orally from the rumen of the cow. The operating conditions of the detection device are recorded in the detection device ahead of time, and can be updated by means of a wireless signal transmitted from a setting unit to the detection device.

Abstract: A method for quantitative determination of nickel and/or copper, by which an ultratrace amount of nickel and/or copper contained in a liquid sample can be easily and simply determined in situ; and apparatus to be used in the method. The method comprises a step of adding a complex-forming agent capable of forming a complex with nickel and copper to a liquid sample containing nickel and/or copper in unknown concentrations to form colored fine particles of a nickel complex and/or a copper complex and a step of determining the quantities of nickel and/or copper on the basis of the colored fine particles.

Abstract: A USB transducer includes: an input section which receives a measurement signal from a measuring device; a controller which converts measurement data into digital data and further converts the digital data into data ready for processing by a computer; and an output section having a USB connection terminal for outputting the data generated by the controller to the computer by using a USB cable, and for receiving a control signal from the computer.

Abstract: The present invention is directed to the provision of a user-friendly system that ensures freedom for incorporating the measuring system into other equipment, reduces a conversion error associated with signal conversion, reduces the cost of an A/D converter, and allows simultaneous processing of a plurality of data. A USB transducer according to the present invention comprises: an input section which receives a measurement signal from a measuring device; a controller which converts measurement data into digital data and further converts the digital data into data ready for processing by a computer; and an output section having a USB connection terminal for outputting the data generated by the controller to the computer by using a USB cable, and for receiving a control signal from the computer.

Abstract: This invention relates to packing methods and materials for packing electrolytic capacitors and the like. This invention provides packing methods whereby capacitors are held in a container tray with a good order and with no rotational movement of capacitor and packing materials wherein packing of electrolytic capacitors solves the problem of capacitor rotation and allows the capacitors to be easily taken out of the container tray. According to this invention, an electrolytic capacitor loaded container tray is taken out of a receptacle and the electrolytic capacitors held in the container tray in an orderly manner can be smoothly picked up for automatic mounting on printed wiring boards.
