摘要:
A lithographic apparatus which performs drawing on a substrate with a charged-particle beam, includes an optical system having an aperture plate in which a first number of apertures are formed to pass a first number of charged-particle beams to perform the drawing, a substrate holder, a cleaning unit configured to clean the aperture plate, and a chamber containing the optical system and the substrate holder. The cleaning unit includes a case having an emitting hole plate in which a second number of emitting holes are formed, the second number being smaller than the first number, an active species source configured to generate active species in the case, and a driving mechanism configured to move the case.

This invention relates to an anti-dementia agent which uses a BEC 1 potassium channel inhibitor as the active ingredient.It was proved that the BEC 1 potassium channel inhibitor has an action to improve learning disorder and is useful as a preventive or therapeutic agent for diseases, preferably dementia, in which the BEC 1 potassium channel is considered to be concerned.Illustratively, it was confirmed by an in vivo test that the BEC 1 potassium channel inhibitor has an action to improve learning disorder.Also, it was found that a compound having 2,4,6-triamino-1,3,5-triazine has a BEC 1 potassium channel inhibitory action.

摘要:
An optical apparatus includes an optical device arranged on an optical path extending from a light source to a predetermined position, an optical sensor, and a measuring device which measures an optical characteristic or a change in an optical characteristic of the optical device on the basis of an output from the optical sensor. The optical sensor is arranged outside the optical path and senses light which is emitted from a second light source arranged outside the optical path and is reflected by the optical device.
