Patent DE-3812684-A1 (DE)
Title: Method for fast scanning of uneven surfaces with the scanning tunnel microscope
Inventor: DRANSFELD KLAUS PROF DR
IPC: G01Q60/16
Filed: 1988-04-16
Abstract: In tunnel-microscopy scanning, the tunnel current between a tip (7), guided as scanning electrode in the x-y direction over the surface, and the opposite surface (3) is determined as measured value. The setting voltage which varies as a function of the tunnel current, for setting the height of the tip in this case provides an indication of the properties of the surface. The height-setting of the tip (7) is carried out by means of a piezo crystal (1) on whose surface the sample (3) is arranged and which is excited by a broad-band measurement amplifier (9) which is fed by the tunnel current and whose upper limit frequency is far above the piezo crystal resonance frequency and whose output voltage at first causes only a surface deformation on the piezo crystal (1) which propagates at the speed of sound into the crystal interior and leads, without time delay, to a deflection speed of the surface which is proportional to the applied voltage at any point in time. <IMAGE>

Title: Circuit arrangement for measuring peak values
Inventor: KREIS WALTER DIPL ING
IPC: G01R19/04
Filed: 1988-09-17
Abstract: The invention relates to a circuit arrangement for measuring peak values of a signal varying with time which is superimposed on a direct-voltage pulse. For the wide band measurement of the peak value of the time-variable signal, two different channels having a common input stage, a common output stage and other means by means of which the component of the direct-voltage pulse is eliminated are provided. This is achieved by the fact that an input signal consisting of the component of the direct-voltage pulse and the component of the time-variable signal is inverted by the circuit means of one channel and the peak voltage value is generated whilst the peak voltage value of the non-inverted input signal is generated by circuit means in the other channel and both peak voltage values are added in the output stage.

Title: Process and filling substrate for planting woody plants
Inventor: FABRITZ GERHARD
IPC: A01G23/00
Filed: 1988-12-02
Abstract: The invention relates to a process and to a filling substrate for planting woody plants, in particular trees of all types. It has been shown that, when planting a tree, filling the tree trench with the known substrates, such as peat, wood chips, bark mulch and with nutrients of enriched soil is not sufficient to ensure healthy growth of the tree. In particular, the vibration compaction, caused by road traffic, of the soil in the root region can result in the tree dying. The fines sinking into the bottom level cause, as a result of silting, damage to the roots and permanent damage to the so-called soil tilth. In order to avoid such damage, the object of the invention is, by suitable measures, to prevent vibration compaction, along with simultaneous segregation, as well as a decreasing total exchange capacity of the fines in the soil due to shifting into lower levels. The object is achieved in that, in accordance with Figure 1, the bottom 1 of a planting hole is worked so as to be planar or horizontal, and a layer of weather-resistant substrate parts 2, preferably in panel form, is applied thereon. This is in connection with vertically upright drainage columns 3 which are introduced on the side walls, and poured in the form of a ring on the layer of the substrate parts are alternate layers of stone fragments 4 and substrate parts 5, and the centre of this poured-on material is ... with a mix 6 comprising clay, humus and soil ...
