Patent DE-3704135-A1 (DE)
Inventor: ROEHM GUENTER HORST
IPC: B23B31/10
Filed: 1987-02-11
Abstract: The clamp jaws radially adjustable by a drive member each comprise a jaw base guided in the chuck body and a mounted jaw member replacably attached with it as well as at least one connecting pin which is mounted pivotable about the pin axis in the jaw base. According to rotary position the attachment between the jaw base and the mounted jaw member is released or locked. At least one control rod guided longitudinally slidable in the jaw base is coupled with the connecting pins by gear teeth so that the motion of the control rods relative to the jaw base converts to a rotation of the connecting pin and vice versa. The feed of the control rods in the jaw base runs parallel to the feed of the jaw base in the chuck body. For the control rod a controlling member is provided by which the control rod is held fixed from motion relative to the chuck body. The jaw base is slidable for rotation of the connecting pins by its drive member with the control rods held fixed in position. Thus with the control rod held fixed the connecting pins are rotated under force by motion of the jaw base.

Patent DE-3725410-A1 (DE)
Title: Photodiode
Inventor: BENEKING HEINZ PROF DR RER NAT
IPC: H01L31/105
Filed: 1987-07-31
Abstract: The charge carriers generated photoelectrically outside the space charge zone of a photodiode must firstly diffuse to the edge of the space charge zone before they are extracted there by the electric field and accelerated to the neutral semiconductor region located opposite. Since the rate of diffusion is generally lower than the drifting rate, the dwell time of the charge carriers outside the field region increases and thereby leads to a higher recombination probability. The consequence of this is that the internal quantum efficiency is lowered and the switching times are lengthened. Consequently, in accordance with the invention, means are provided outside the space charge zone which generate a drift field which accelerates the charge carriers towards the space charge zone.

Patent DE-3734124-A1 (DE)
Inventor: TEGTMEIER UWE DR
IPC: C12M1/12
Filed: 1987-10-09
Abstract: Low aliphatic alcohols or organic solvents, especially ethanol are continuously produced by fermentation from sugar containing nutrient substrates. The process includes two fermentation steps or stages in which the substrate is subjected to the effects of microorganisms such as yeast. The first fermentation stage has a volume of 10 to 20% of that of the second fermentation stage. By adjusting the environmental conditions in each stage a large cell growth with a small portion of the total supplied substrate quantities takes place in the first activation stage and a high product formation rate is achieved with a considerably larger portion of the entire supplied substrate quantity in the second production stage. A partial outflow stream from the first stage is microfiltered and the permeate as well as the unfiltered outlet flow of the first stage, is directed into the second stage. The outlet flow of the second stage is microfiltered and the concentrate is partly discharged as a product output stream and partly returned to the second stage. The transfer flow and return flow streams and the discharge of the permeate and the product streams from the second stage are adjusted so that, for dwell times of the cell mass of up to two hours in the first stage and up to 15 hours in the second stage, an average cell age of 40 to 100 hours is achieved with a corresponding high yield output.
