  • Publication number: 20250037969
    Abstract: In one embodiment, a charged particle beam writing apparatus includes a high-voltage power supply configured to apply an acceleration voltage for charged particles to an emission unit, a deflector configured to deflect a charged particle beam emitted from the emission unit, a discharge sensor configured to output an output value indicating a change in a case where a discharge occurs in a column in which the emission unit and the deflector are arranged or in the high-voltage power supply, and a discharge detection control unit configured to convert the output value from the discharge sensor into a conversion value with the same sign, calculate an integral value of the conversion value over a fixed period of time, and determine, based on the integral value, whether or not a discharge that causes a pattern error has occurred.

  • Patent number: 9170770
    Abstract: A vehicle controller has multiple vehicle control modes that have different output characteristics of a travel power source relative to an accelerator operation amount. The vehicle control modes include a poor road travel mode used during travel on a poor road, and a first normal travel mode and a second normal travel mode that are used during travel other than on a poor road. A rate of increase in an output of the travel power source relative to a predetermined accelerator operation amount during an initial stage of an accelerator operation is set to increase steadily in order of the poor road travel mode, the first normal travel mode, and the second normal travel mode. When the poor road travel mode is selected, a mode transition to the first normal travel mode is permitted but a mode transition to the second normal travel mode is prohibited.
