Patent DE-3829770-A1 (DE)
Inventor: BRUST HANS-DETLEF
IPC: G01R31/28
Filed: 1988-09-01
Abstract: PCT No. PCT/DE89/00570 Sec. 371 Date Jan. 31, 1991 Sec. 102(e) Date Jan. 31, 1991 PCT Filed Sep. 1, 1989 PCT Pub. No. WO90/02955 PCT Pub. Date Mar. 22, 1990.In conventional processes of electron beam measuring, the measurement of signals at a measuring point of a sample occurs following scanning and averaging procedures with the aid of potential contrasts. For this purpose, the point of measurement is impinged upon with a short primary electron pulse, which is released by a trigger pulse, which is synchronous to the signal to be measured. The average value of the secondary electron pulse stream resulting from very many primary electrons is measured and is a measure for the signal at the measuring position at the point in time of the impingement of the primary electrons. The generation of primary electron pulses occurs with a beam modulation system. As the primary electron pulses are generated in response to the trigger pulses, this system has to be designed very widebanded. In operation, the sample is impinged upon with primary electron pulses completely in independence of the signal course at the measuring position, and the resulting secondary electron stream is registered. For the evaluation, only the secondary electron pulses resulting from the primary electron pulses occurring in a defined temporal interval from the respective trigger pulse are utilized. In order to record a complete measurement curve, this temporal interval is varied.

Title: Additional handle
Inventor: DEUSCHLE HEINZ
IPC: B25F5/02
Filed: 1988-09-02
Abstract: A description is given of an additional handle for powered hand tools which can be clamped on the spindle neck (20) of the machine, comprising a resilient clamping ring (1) which is separated by a slot (12) and whose ends (2, 3) are penetrated by the clamping screw (4) and whose one end (2) receives a depth stop (5), and comprising a locking nose (7) which plunges into a groove (21) situated on the spindle neck (20) of the hand tool and thus prevents axial displacement of the additional handle on the spindle neck. The locking nose (7) is arranged on a sleeve (8) which is displaceable along the clamping screw (4) in the ends (2, 3) of the clamping ring (1) and extends only over part of the length of the sleeve (8), so that, if the sleeve (8) is fitted onto the clamping screw (4) the other way round, the locking nose does not project into the opening (1') of the clamping ring (1). <IMAGE>

Title: Video adapter
Inventor: PIENKOWSKI MIROSLAW
IPC: H04N5/775
Filed: 1988-11-04
Abstract: Because of their high-quality image, Super-VHS video units are accepted more and more. However, it is disadvantageous in these units that the luminance (Y) and chrominance (C) lines brought in separately can not be processed by normal television sets. The invention proposes an adapter which conditions the incoming (Y) and (C) signals in such a manner that they can be supplied as "RGB" signals to the SCART connector (6) normally provided on such television sets. <IMAGE>
