The present invention has been made in view of the above problems, and an object thereof is to provide a charged particle beam device capable of improving the reproducibility of the magnetic field response of a magnetic field lens and realizing highly-accurate electron orbit control in a short time. A charged particle beam device according to the present invention generates an excitation current of a magnetic field lens by combining a direct current with an alternating current (see FIG.A).

Charged particle beam device, and method for controlling charged particle beam device

A charged particle optical system includes an aberration correctorthat corrects aberration of a charged particle beam and has multipoles of a plurality of stages. The aberration corrector generates a plurality of multipole fields in a superimposed manner for each of the multipoles of the plurality of stages in order to correct the aberration of the charged particle beam. In order to reduce the influence of a parasitic field due to distortion of the multipole, for a first multipole field to be generated in a multipole of any stage among the plurality of stages, a value of a predetermined correction voltage or correction current to be applied to a plurality of poles for generating the first multipole field is corrected so as to eliminate movement of an observation image obtained based on electrons detected from a detectorby irradiating a sample with the charged particle beam before and after the first multipole field is generated.

Charged particle beam device and aberration correction method

Provided is a technique capable of setting an appropriate link destination when there are a plurality of link destination candidates among data files. A file management system according to the present invention determines a type of a target indicated by a character string described in a data file to determine whether the target matches among data files and assigns a link among the data files when the target matches.

File management system and work support system

A washing and drying machine includes: a washing drum for accommodating the washings and rotating under a driving force of a motor; an air supply portion for supplying air into the washing drum; a heating portion configured to heat the air to be supplied into the washing drum when turned on and stop heating when turned off; and a control portion for controlling the motor, the air supply portion and the heating portion to execute a washing and drying operation. A drying procedure in the washing and drying operation includes main drying treatment repeated for multiple times. During each time of the main drying treatment, the control portion is configured to keep the heating portion being on within a first period, and keep the heating portion being off within a second period different from the first period, and the second period is longer than the first period.

A head-mounted display () includes: an imaging assembly () imaging scenery seen by a user to generate a source picture; a storage unit () storing color correction factors used for correcting brightness of each of a red, green and blue color components included in a picture; a correction picture generator () performing color correction processing for enhancing a color component with a relatively low color correction factor stored in the storage unit (), of the red, green and blue color components forming the source picture, to generate a correction picture; a picture display assembly () displaying the correction picture in the field of view of the user under a condition where he/she is able to perceive the outside world; and a special picture processor () performing picture processing for overlaying the correction picture and the source picture on each other for display.

Head-mounted display, head-up display and picture displaying method

There are provided a dimmer that can solve practical problems including burn-in and easily change a transmittance to external light and a video display device using the same. A dimmer includes a stack of two or more light control layers that change a transmittance to incident light by controlling an applied voltage in the incident direction of the incident light. A video display device includes a video generator that generates picture light; a video projector that projects the picture light as a virtual image in the field of view of a user; the dimmer disposed on the opposite side of the projecting side of the video projector to the user for adjusting the light quantity of external light to be entered to a user's eye through the video projector; and a light controller that controls the dimmer suitable for the luminosity of external light detected at an external light detector.
