Patent EP-0314763-B1 (EP)
Title: Secondary electron detector for use in a gaseous atmosphere
IPC: H01J37/28
Filed: 1988-05-17
Granted: 1993-03-03
Abstract: The invention provides for a device and method for generating, amplifying, and detecting secondary electrons from a surface of a sample. The device contains a vacuum envelope (1) having a pressure limiting aperture (2), a charged particle beam source (3), means (4, 5) for focusing and directing the charged particle beam through the aperture (2) to a sample mounted on a sample platform (6) located in a gaseous environment outside of the vacuum envelope (1), an electrode (7) located outside of the vacuum envelope (1) and close to the sample platform (6). In operation, the electrode is biased by a voltage source (8) to accelerate secondary electrons emitted by the sample so that they collide with gas molecules to produce negative charge carriers which multiply by further collisions. The negative charge carriers are collected by the electrode (7) to produce a current which is amplified by a current amplifier (4) and output to a detector (10).

Patent EP-0326220-B1 (EP)
IPC: H02M3/155
Filed: 1989-01-24
Granted: 1993-09-29
Abstract: A circuit arrangement for feeding a load (3) from a low voltage energy source (1) via a direct-voltage conversion circuit (2). The direct-voltage conversion circuit periodically takes energy from the energy source by means of a main switching element (10) and supplies this energy as an increased supply voltage (at 12) to the load via an inductive element (9) and a rectifier (11). A starting switching element (15) takes energy for generating the supply voltage (at 12) from the energy source during a starting phase. The circuit arrangement is simple and compact and the energy losses produced are so low that it is economic to use it for energizing a small appliance particularly a small domestic appliance, from a battery or a rechargeable accumulator. A main control circuit (13) is supplied with energy directly from the supply voltage (at 12) and periodically controls the main switching element. A starting control circuit (16) is fed directly and exclusively from the energy source and periodically controls the starting switching element (15) so that is switching periods are shorter than those of the main switching. The starting control circuit, and thus the starting switching element, are switched off when the supply voltage reaches a predetermined value.

Abstract: In this method, destination calls requested in elevator cabins (CABIN.1 ... CABIN.n) in elevator control systems with immediate assignment of the destination calls requested at the floors (E0 ... EN) are treated according to an algorithm (CONTROLLER.K) implemented in the process computer (COMPUTER). Preliminary treatment of the cabin destination calls is effected when they are requested and final treatment of the cabin destination calls is effected before the floor of the cabin destination call. Cabin destination calls coinciding with assigned destination calls are immediately assigned during the preliminary treatment. The remaining cabin destination calls are shortened by one floor and recorded. The cabin destination calls recorded during the preliminary treatment are assigned in their original length during the final treatment in case there are similar assigned destination calls. The final treatment of the remaining cabin destination calls is effected as a function of the assigned destination calls before and/or after the floor of the cabin destination call.
