Abstract: With a resistor, a variable resistor, and a method for manufacturing a resistor according to the present invention, it is possible to eliminate lead and prevent deterioration of sliding characteristics. A resistor according to the present invention is disposed on an insulating layer. The resistor has: a more-conductive-material-containing layer containing more conductive materials than insulating materials; and a more-insulating-material-containing layer that does not contain lead and that contains more insulating materials than conductive materials. The more-conductive-material-containing layer has a polished surface. For example, the film thickness of the more-conductive-material-containing layer in a low-resistance region having a resistance value smaller than or equal to a prescribed value is larger than the film thickness of the more-insulating-material-containing layer in a high-resistance region having a resistance value larger than the prescribed value.

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.
