  • Patent number: 12179278
    Abstract: A gear-grinding multilayer grindstone includes: a first thread-shaped grindstone and a second thread-shaped grindstone that are fixed to each other, such that the first and second thread-shaped grindstones have a rotational axis that is common to the first and second thread-shaped grindstones; and a thread-shaped groove that is provided in a first outer circumferential surface of the first thread-shaped grindstone and a second outer circumferential surface of the second thread-shaped grindstone. The thread-shaped groove extends continuously over the first outer circumferential surface and the second outer circumferential surface. The second thread-shaped grindstone is constituted by abrasive cloths that are laminated on each other, and has a higher elasticity than the first thread-shaped grindstone.

  • Patent number: 9128161
    Abstract: A voltage monitoring device monitors voltage of each of battery cells connected in series to one another to configure an assembled battery. The device includes a capacitor circuit, a filter circuit, an input side connection switching unit, a potential difference detection unit, and an output side connection switching unit. The capacitor circuit includes a plurality of capacitors connected in series to one another. The filter circuit includes a plurality of resistors connected to an electrode terminal of each of the battery cells. The plurality of resistors are divided into a first resistor group and a second resistor group. The first resistor group is connected to a connection point between adjacent capacitors of the plurality of capacitors. The second resistor group is connected to an independent end of the plurality of capacitors. A resistance value of the first resistor group is smaller than a resistance value of the second resistor group.

  • Patent number: 6774580
    Abstract: An inverter circuit for a discharge tube of the present invention comprises a transformer in which a resonance circuit is composed of a parasitic capacitance of a discharge tube, and a H-bridge circuit which drives the primary side of the transformer at a frequency that is lower than the resonance frequency of the resonance circuit and that involves a phase difference between the voltage and the current at the primary side of the transformer, the phase difference falling within a predetermined range from its minimum point.
