Abstract: A liquid ejecting head control circuit controls a liquid ejecting head and a switching circuit. The liquid ejecting head control circuit includes a drive signal output circuit, and a switching control circuit. The switching control circuit outputs an ejection control signal defining an amount of a liquid to be ejected from a nozzle, a switching timing signal defining switching timing of the switching circuit, and a state selection signal defining a state of the switching circuit in a control period defined by the switching timing signal. The state selection signal for a first time period for which the liquid ejecting head is controlled so as to eject the liquid from the nozzle is different from the state selection signal for a second time period for which the liquid ejecting head is controlled so as not to eject the liquid from the nozzle.

Abstract: Provided is a charged particle beam device capable of observing the interior and the surface of a sample in a simple manner. This charged particle beam device operates in a transmitted charged particle image mode and a secondary charged particle image mode. In the transmitted charged particle image mode, a transmitted charged particle image is produced on the basis of a detection signal (512) associated with light emitted from a light-emitting member (500) that emits light upon being irradiated with transmitted charged particles transmitted through the interior of a sample (6). In the secondary charged particle image mode, a secondary charged particle image is produced on the basis of a detection signal (518) caused by reflected charged particles or secondary charged particles (517) from the sample (6).

A thin film is provided to separate the inside of the first housing and the inside of a second housing at least along part of the interface between the first and second housings. An opening part is formed in the thin film so that its opening area on a charged particle irradiation unit's side is larger than its opening area on the sample side; and the thin film which covers the sample side of the opening part transmits or allows through the primary charged particle beam and the charged particle beam.
