Patent DE-3807912-C1 (DE)
IPC: H03H7/46
Filed: 1988-03-10
Granted: 1989-07-20
Abstract: In known diplexers for separating a total frequency range into at least two part-frequency ranges or connecting these together, via which a remote power feeding current is fed into the connecting point of a branch, constructed, for example, as high-pass filter, for a higher part-frequency range for supplying an active component with operating current, this branch exhibiting at least one series capacitor and a shunt inductance connected to its connecting point, the high-pass filter is bypassed by a choke (D) for the transmission of the remote power feeding current (Figure 1). Due to the inter-turn and stray capacitance of this choke (D), the transfer characteristics of the diplexer are greatly impaired at high frequencies and/or feed currents. To avoid or at least to minimise this disadvantageous effect, it is proposed that the shunt inductance (L7) connected at the connecting point (A2) of the branch (4) for a higher frequency range (first satellite intermediate frequency range) is connected to earth via a bypass capacitor (C7) and the junction point (P1) of these two reactances (L7, C7) is connected via a choke (Dr1, Dr2) to a circuit point (P2) of a branch (3) for a lower part-frequency range (40 to 860 MHz), which is connected via at least one inductance (L1, L2, L4) to the separating point (A) or junction point of the diplexer (1). <IMAGE>

Title: Control valve
IPC: F16K39/02
Filed: 1988-05-11
Granted: 1989-03-16
Abstract: The control valve has a valve housing with an inlet and an outlet branch and a valve spindle (1) which is guided in a sealed and axially displaceable manner in the said housing and has a valve element which interacts with a valve seat between the inlet and the outlet branch, is balanced on the inlet and outlet side and, at its end remote from the valve spindle, is provided with a balance piston (2). The balance piston (2) is guided in a sealed manner in an extension (3) of the valve housing, a first stuffing box packing (4) being inserted between them, this being held by an axially adjustable cup-shaped closing part (6) which fits over the outer end of the balance piston (2) to form a balance chamber (5), the balance chamber (5) being sealed off from the outside by a second stuffing box packing (10) separated from the first stuffing box packing (4). This second stuffing box packing (10) is arranged between the interengaging surfaces (6a, 3a) of the closure part (6) and the extension (3) and between contact surfaces (11, 12) lying in series in the axial direction of the balance piston. <IMAGE>
Patent DE-3819017-C1 (DE)
IPC: D05B1/24
Filed: 1988-06-03
Granted: 1989-04-13
Abstract: Blind-stitch sewing machine with a fabric bender (3) driven to oscillate for the purpose of curving the material to be sewn (4) into the arcuate path of movement of the curved needle (2), its shortest distance from the path of movement of the curved needle (2) being adjustable according to the thickness of the material to be sewn determined by means of a material sensor (33). There are provided a stepping motor (16) for adjusting this minimum fabric-bender distance and a control circuit (52) for the stepping motor (16), which is connected to the material sensor (33), to a curved-needle/fabric-bender contact indicator (29) and to a measuring-window signal transmitter (26) and which so controls the stepping motor (16) that, in response to a starting signal (B') for the control circuit (52), it runs into a specific starting position (a) and, during subsequent sewing, runs one step further for each stitch, with a further reduction of the minimum fabric-bender distance, until the indicator (29) supplies a curved-needle/fabric-bender contact signal (C) in the course of a measuring-window signal (A). At the end of this, the stepping motor (16) runs in the opposite direction over a number of steps dependent on the output signal of the material sensor (33), so that the minimum fabric-bender distance increases accordingly.

Title: Process for the deposition of tin on substrate surfaces
IPC: G03F1/00
Filed: 1988-09-15
Granted: 1989-11-23
Abstract: Processes for the deposition of metals on substrate surfaces are used for the repair of X-ray masks or conductor tracks on semiconductor chips. The photolytic deposition from the gas phase allows controlled deposition from a spatially narrowly confined area. The disadvantage of this method is the low deposition rate. Existing measures for increasing the deposition rate lead to a heavy stress on the substrate material. The novel process increases the deposition rate by an order of magnitude without increasing the stress on the substrate material. The deposition rate is increased by mixing the process gas before the deposition with oxygen in a ratio of 1:1. During the process indicated, for example the repair times of clear defects on X-ray masks are reduced from about 20 minutes to about 2 minutes.
