  • Publication number: 20220246396
    Abstract: In one embodiment, a waveform generating device includes a first DA converter converting input data, a controller outputting a first signal having a command value based on the input data, and a second signal having a command value differing by a constant value from the first signal, a second DA converter converting the first signal, a third DA converter converting the second signal, and a combiner combining the output of the first DA converter, the output of the second DA converter, and the output of the third DA converter. When a value of a predetermined first high-order bit of the input data is inverted, the controller changes the command value of the first signal such that a value of the first high-order bit or a second high-order bit different from the first high-order bit is inverted.

  • Publication number: 20210398155
    Abstract: A computing device includes a fuel price identifying unit that is configured to identify, based on a load plan and information on prediction of weather conditions, a fuel price in a case where motive power of a cooling water cooling device is varied, and a balance identifying unit that is configured to identify, based on the selling price of the generated electric power and the fuel price, at least a balance that is greater than a balance obtained by generated electric power according to the load plan in a case where a current operation is continued.

  • Patent number: 11171395
    Abstract: An object is to provide a transmission line having an air bridge structure in which grounding conductors of a transmission line are connected by wiring and which is stable in terms of mechanical strength by lowering an electrostatic capacitance in a region where the wirings connecting the central conductor and the grounding conductor intersect with each other. The transmission line includes a substrate, a first central conductor and a second central conductor that are formed on a surface of the substrate, a third central conductor that has a first erection portion and a second erection portion erected on the surface, and a first grounding conductor and a second grounding conductor. The transmission line further includes a third grounding conductor connecting the first grounding conductor and the second grounding conductor. The third central conductor and the third grounding conductor form an air bridge structure.

  • Patent number: 10998280
    Abstract: Provided is a balance-unbalance converter including: a substrate; an unbalanced line; a first balanced line; and a second balanced line on the substrate. The unbalanced line has a first end at which an unbalanced signal is input, and an opened second end. The first balanced line is in parallel with a line portion of the unbalanced line from the first end to a midpoint of the unbalanced line, and has a midpoint-side third end at which a balanced signal is output, and a grounded fourth end. The second balanced line is in parallel with a line portion of the unbalanced line from the second end to the midpoint, and has a midpoint-side fifth end at which the balanced signal is output, and a grounded sixth end. The unbalanced line is bent at the midpoint toward an opposite side of the first and second balanced lines.
