  • Patent number: 8668820
    Abstract: A method of measuring a quantity of a substrate contained in sample liquid is provided. This method can reduce measurement errors caused by a biosensor. The biosensor includes at least a pair of electrodes on an insulating board and is inserted into a measuring device which includes a supporting section for supporting detachably the biosensor, plural connecting terminals to be coupled to the respective electrodes, and a driving power supply which applies a voltage to the respective electrodes via the connecting terminals. One of the electrodes of the biosensor is connected to the first and second connecting terminals of the measuring device only when the biosensor is inserted into the measuring device in a given direction, and has a structure such that the electrode becomes conductive between the first and second connecting terminals due to a voltage application by the driving power supply.

  • Patent number: 8448488
    Abstract: A round steel rod having a carbon content between 0.30 and 0.60% is processed by a cold working process to form a flat wire for forming a ring gear. The cold working process forms a semifinished flat wire by at least one cold rolling or cold roller drawing step and at least one two-way or four-way rolling step. The semifinished flat wire is processed by die drawing using a drawing die to obtain a finished flat wire in a last stage of the cold working process. The cold working process reduces the round steel rod at a total area reduction of 65% or below.
