  • Publication number: 20240154040
    Abstract: A semiconductor device capable of measuring a minute current is provided. The semiconductor device includes an operational amplifier and a diode element. An inverting input terminal of the operational amplifier and an input terminal of the diode element are electrically connected to a first terminal to which current is input, and an output terminal of the operational amplifier and an output terminal of the diode element are electrically connected to a second terminal from which voltage is output. A diode-connected transistor that includes a metal oxide in a channel formation region is used as the diode element. Since the off-state current of the transistor is extremely low, a minute current can flow between the first terminal and the second terminal. Thus, when voltage is output from the second terminal, a minute current that flows through the first terminal can be estimated from the voltage.

  • Publication number: 20240151058
    Abstract: An object of the present invention is to provide a utility pole and a method for constructing the utility pole, which can simplify and improve efficiency of work at the time of new construction and replacement and can shorten a work period. The anchor has a larger diameter than a body of a utility pole on the ground and has higher ground support force. Thus, the hole for building the assembly type utility pole on the ground can be made shallower than the hole for building the utility pole in related art on the ground. The depth of the hole is shallow, so that it is possible to reduce a period for digging, reduce a probability of hitting a buried object, and reduce work for confirming a buried object. In addition, the assembly type utility pole includes a plurality of parts, and thus, only a degraded portion needs to be replaced, so that it is possible to shorten replacement work.

    Abstract: The present technology relates to an information processing apparatus capable of more easily determining a maintenance timing by using event data. The information processing apparatus includes a state estimation unit that estimates a state of a grindstone by using event data supplied from an event sensor that outputs, as event data, a temporal change of an electrical signal obtained by photoelectrically converting an optical signal, and outputs a result of the estimation. The present technology can be applied to, for example, an information processing system or the like that tells a maintenance timing of a grindstone of a machine tool.
