    摘要： A magnetic-balance-system current sensor includes: a magnetoresistive element, a resistance value of the magnetoresistive element being changed by applying an induction magnetic field generated by a measurement target current; magnetic cores disposed near the magnetoresistive element; a feedback coil disposed near the magnetoresistive element and configured to generate a cancelling magnetic field that cancels out the induction magnetic field; and a magnetic-field detecting bridge circuit having two outputs. The measurement target current is measured on the basis of a current flowing through the feedback coil when the induction magnetic field and the induction magnetic field and the cancelling magnetic field cancel each other out. The feedback coil, the magnetic cores, and the magnetic-field detecting bridge circuit are formed on a same substrate. The feedback coil is of a spiral type, and the magnetic cores are provided above and below the feedback coil.

    摘要： A magnetic balance type current sensor measures a measured current which flows in a feedback coil when electrical conduction is provided by a voltage difference according to an induction magnetic field from the measured current and an equilibrium state is reached in which the induction magnetic field and a cancel magnetic field cancel each other. Sensor elements in a pair are arranged at positions with magnetic field from the measured current. The magnetization direction of the pinned magnetic layer in the magnetoresistive effect element of one sensor element is aligned in a forward direction with respect to the magnetic field formed by the measured current. The magnetization direction of the pinned magnetic layer in the magnetoresistive effect element of the other sensor element is aligned in a reverse direction with respect to the magnetic field formed by the measured current.

    摘要： Magnetoresistive effect elements R1 to R4 are a TMR element or CPP-GMR element. A multilayer film forming the magnetoresistive effect elements is formed to have a width dimension T1 and a length dimension L1 perpendicular to the width dimension T1. The length dimension L1 is longer than the width dimension T1. The width dimension of magnetic field generators of the coil is T2. The multilayer film 31 is positioned within the width dimension T3 of 60% in total of 30% each to the width dimension T2 of the magnetic field generators 3 and 4 of the coil in the direction towards both sides from the center of the width dimension T2 when seen in a plan view.

    摘要： A current sensor includes a magnetic detecting element, a bridge circuit including a plurality of resistance elements, and a feedback coil placed adjacent to the magnetic detecting element and generating a cancelling magnetic field for cancelling the induced magnetic field based on the output from the bridge circuit. The wiring patterns forming the bridge circuit are routed so as not to intersect with each other when seen in a plan view. Only the resistance elements constituting each series circuit of the bridge circuit are connected to each other by the wiring pattern in an enclosed area which encloses each resistance element constituting the bridge circuit, and the wiring pattern branched from the wiring pattern is connected to the terminal which is installed in a quantity of only one, outside the enclosed area.

    摘要： The present invention provides a device and a coffee production method which are capable of extracting coffee from which an unfavorable taste is removed as much as possible. There is provided a coffee extraction device including an extractor that has a hollow portion which has an internal space for containing a liquid, a bottom portion which is disposed below the hollow portion, and a tube portion which ascends from the bottom portion and descends again so as to discharge the liquid to a lower portion of the bottom portion, and a filter portion that is capable of filtering ground coffee beans, and that has an engagement portion for engaging with the extractor in order to be placed at a predetermined position from the bottom portion of the extractor. The filter portion is placed in the hollow portion of the extractor so that the tube portion achieves a siphon effect.
