Patent DE-2705417-A1 (DE)
Title: Gating device for beam of electron microscope - has slot formed by deflecting electrodes, to which HF pulses are applied
Inventor: HIEKE EDUARD DIPL ING DR
IPC: H01J37/26
Filed: 1977-02-09
Abstract: The gating is done at a high repetition frequency. An electrostatic deflection system electrodes form a slot parallel to the beam axis and symmetrical to it. The electron beam is intermittently so deflected that it falls on a catcher electrode and is drained away by it. The slot width does not appreciably exceed the beam dia. before its entry in the slot (9). The electrodes (7, 8) carry a bias voltage (-Uo) which deflects the part of the beam entering the slot (9) by a smallest angle necessary to guide it completely to the electrode (7). A pulse generator (11) generates a very high frequency gating pulses (Ui) of very short duration, of which only a part of their peaks is superposed on the voltage (-Uo).

Title: Dishwasher water softening unit - has adjustable water switch directing water to ion exchanger or directly to wash container
Inventor: DEISS ULRICH
IPC: A47L15/42
Filed: 1977-04-14
Abstract: The water softening unit for dishwashers includes an ion exchanger container and a salt container preceded by a water collecting container (14). This has a water switch (36) at the outlet (33) of the supply pipe (17), timed to release fresh water. According to the position of the switch tongue (37) water can be supplied via the water switch to the collecting container and/or to the wash container. The amount of brine to regenerate the ion exchanger contents and which depends on the hardness of the water treated in the ion exchanger can thus be readily altered by adjusting the switch tongue and thus by altering the water take up in the water collecting container. The water switch preferably has a handle which can be actuated from inside the wash container and positively connected to the switch tongue. This allows a simple adjustment of the amount of water to be collected in the water container (14) which depends on the hardness of the water supplied to the machine.

Title: Semiconductor prodn. using electron beam irradiation - removes interfering stray effects by generating field strength between semiconductor and electro-resist layer deflecting electrons inwards
Inventor: BENEKING HEINZ PROF DR RER NAT
IPC: H01J37/317
Filed: 1977-07-22
Abstract: The interfering stray effects during the electron beam irradiation are removed from a semiconductor device coated with an electro-resist layer. In the close vicinity of the boundary region between the semiconductor and this layer is generated for this purpose a field strength, sufficient to deflect stray electrons, propagated from the semiconductor in the boundary region, into the semiconductor inside. In order to generate the electric field the electro-resist layer has a surface terminal at a negative potential in relation to the semiconductor. The field strength approaches the breakdown field strength of the layer, or of a high-ohmic layer underneath. Typically field strengths ranging from 1 to 10 MV/cm.

Title: Multidimensional movement control system - divides path into stages with stopping positions passed only on signal
IPC: G05B19/40
Filed: 1978-08-19
Abstract: The system gives accurate control and programming of repeated multi-dimensional movements. The path of each torque- and/or power-transmitting component is divided into stages by stopping positions, and movement of the datum point on the component concerned beyond the stopping position is controlled by data in a main storage unit, which produces a signal, in the absence of any overshooting, when the datum point is in the stage immediately before the stopping position concerned, allowing it to pass the latter. If there is no signal, the point is halted at the next stopping position. If the overshooting, either the speed of emission of data from the storage unit, or that of point movement, is altered dependent on the characteristic of the amount of overshoot.
