Abstract: A particle-optical apparatus comprising a sample holder for receiving a sample, a particle source embodied to produce a primary beam of first electrically charged particles along an optical axis for the purpose of irradiating the sample, first detector embodied to detect second electrically charged particles that emanate from the sample as a result of the irradiation thereof, a detection space that at the least is formed by the sample holder and the first detector, and an immersion lens embodied to produce a magnetic field for the purpose of focusing the primary beam in the vicinity of the sample holder. The first detector are embodied to produce an electric field in the detection space, and the detection space is embodied to comprise a gas.

Abstract: In, for example a field emission display, the invention provides the possibility of combining a plurality of sub-substrates that are attached to a larger rear wall, because notably different modes of multiplexing provide a wider positioning tolerance of a sub-substrate with respect to the front plate. Moreover, the different multiplexing techniques lead to a smaller number of connections, even if no use is made of a rear wall supporting of sub-substrates. A plurality of multiplexing techniques provides the possibility of activating a substantially equally large number of pixels of different colours during parts of an image period, so that there is substantially no colour flicker.

Abstract: An appliance for removing hairs growing from skin is provided with a clamping device and a cutting device cooperating therewith. The clamping device clamps the hairs to be removed and subsequently extracts them at least partly from the skin, whereupon the hairs extracted partly from the skin are cut through adjacent the skin by the cutting device. The hairs thus cut through return to below the surface of the skin, so that a smooth shaving result is achieved which remains intact during a considerable period. According to the invention, the appliance is provided with structure for adjusting an extraction distance over which the clamping device extracts the hairs from the skin before they are cut through by the cutting device. In a special embodiment, the structure is adjustable to a first mode in which the appliance purely has a shaving function and to a second mode in which the appliance purely has a depilation function.

Abstract: A new and distinct cultivar of Astilbe plant named ‘Vision in White’, characterized by its upright and sturdy plant habit; strong and healthy foliage; freely and uniformly flowering habit; white-colored flowers; and good garden performance.
