Patent DE-4204004-A1 (DE)
Inventor: BODENSOHN ALEXANDER DIPL ING
IPC: H01L29/06
Filed: 1992-02-12
Abstract: A vertical semiconductor component (14) may be integrated on a common semiconductor body (1) together with lateral semiconductor components (13) the lateral semiconductor components (13) being insulated from the vertical semiconductor component (14) by means of a pn-junction. One of the inconvenients of this type of insulation is that much space is needed for spreading the space charge region of the pn-junction. It is therefore advantageous to insulate in another manner according to which partial structures (7) containing lateral semiconductor components (13) are laterally surrounded by insulating walls (6). These walls extend from a first surface (2) of the semiconductor body (1) down to a determined depth thereof; in the area of the partial structures (7), the semiconductor body (7) has a second surface (3) that reduces its thickness, in the manner of a recess (9) that extends up to the insulating walls (6). Several vertical components may be integrated in the semiconductor body outside the partial structures (7).

Title: Laser beam cutting device for cutting PCB holes - has reflector arrangement ensuring uniform beam distribution over mask surface
Inventor: ZUMOTO NOBUYUKI
IPC: B23K26/066
Filed: 1992-05-29
Abstract: Laser cutting appts. comprises a laser beam source (103) which passes through a mask (101) after being reflected within an area between the mask and a reflector (102). The reflector is located on the side of the mask nearest the laser source at an angle (Q) to the face of the mask such that the distance between the mask and reflection reduces along the direction (x). The angle (theta 1) is given by (Theta1)=(thetao)(RrxRn)n-1)/(Zn+1-(RrxRm)n) (where Rm is the reflector factor of the mask, Rr the reflection factor of the reflector, n the number of reflections between mask and reflector and theta the incidence angle of the light source on the mask). USE/ADVANTAGE - Laser cutting printed circuit board holes. The laser beam is uniformly dispersed over the whole surface of the mask and the energy loss between mask and reflector is minimised leading to more efficient use of the beam.

Title: Installation for extruding plastics and/or rubber compounds
Inventor: RUEGER WOLFGANG
IPC: B29C48/12
Filed: 1993-02-12
Abstract: The invention relates to an installation for extruding plastics and/or rubber compounds, comprising at least one extruder and an extruder head, in which inserts forming the flow path of the extrudate are exchangeably fitted. It is the object of the invention to provide a simple possibility for a rapid and automatable exchange of the inserts of the extruder head enclosing the flow paths. The invention consists in that the extruder head comprises a housing, which is open at least on one side, and the inserts fitted into it, in that a device for laterally pulling out the inserts from the housing and a device for laterally pushing in inserts into the housing are arranged next to the extruder head and that a device for firmly clamping and sealing in the inserts is provided in the housing. The inserts necessary for this extruder head can be produced in a simple way. The changing of the inserts can be performed extremely rapidly, since the inserts do not have to be removed and exchanged individually, but are exchanged as an assembly. This has the advantage that the exchanging operation can be performed in an automated manner. The downtimes of the extruder for an exchange of inserts can be minimised as a result.

Title: Device for format adjustment of sheet stops
Inventor: KRATZSCH ACHIM
IPC: B65H9/04
Filed: 1993-07-31
Abstract: On known sheet feeders for separated folded sheets, the sheet stops have to be adjusted individually and therefore in a non-linear fashion to the respective format width. Since, additionally, such format adjustments are undertaken without measuring instruments, that is to say cannot be evaluated, the sheet stops often have to be readjusted at great effort. With the device according to the invention, an absolutely accurate, linear adjustment of the sheet stops over their entire adjustment range is possible simultaneously, the operation of the adjustment device being undertaken from only one side of the sheet feeder. The adjustment effort for the sheet feeder is thus reduced considerably. The device according to the invention for format adjustment is used on sheet feeders for gatherer-stitchers. <IMAGE>

Abstract: A telephone private branch exchange system (PBX) with the call diversion facility is described in which selective incoming call protection is implemented. If a selective incoming call protection function which can be activated by the called communications terminal is activated, a control device (CC) of the telecommunications private branch exchange system (PBX) compares a stored selection criterion, e.g. a telephone number sequence, with a selection criterion transmitted by a calling communications terminal (T1) and, depending on the result of this comparison, sets up a connection to a called terminal (T2) or performs a call diversion. It can be provided that a connection is set up to the called terminal (T2) for required subscribers only or that only unwanted subscribers are connected with the aid of a call diversion to a terminal (T3) which is not identical to the called terminal (T2) <IMAGE>
Patent DE-4332755-A1 (DE)
Title: Priming installation for wooden construction elements
Inventor: GAISER MATTHAEUS
IPC: B05B16/40
Filed: 1993-09-25
Abstract: The invention presents a priming installation for the commercial and industrial production of general wooden construction elements, in particular window and door elements. In this priming installation, large and small batches are primed during the use of very small quantities of water-soluble primers without any dripping of the elements by virtue of the fact that they are put into a chamber consisting of two housing halves which can be opened and closed in a vertical plane. In the chamber, the water-soluble primer, introduced through feed nozzles, is swirled, for example by centrifugal fans, to form a mist wetting the wooden elements all over. Accumulated residues of primer and drops are blown out of the grooves and rebates by the subsequent air flow without primer, caused by simple operation of the centrifugal fans without primer, and the drying process is started. Very simple cleaning or re-setting to priming agent is possible by operating the installation with water.

Patent DE-4344913-A1 (DE)
Inventor: WAGNER LARRY
IPC: H04M11/06
Filed: 1993-12-29
Abstract: A transceiver providing simultaneous transfer of control information with voice and data over a public switched telephone network line is disclosed wherein the transceiver is coupled to a public switched telephone network (PSTN) via a single telephone line. The transceiver includes logic for generating control information and for combining the control information with voice signals or data signals for transmission and reception through the PSTN using a single telephone line. The PSTN channel 310 is divided into two component subchannels, a main channel 312 and a side channel 314. The main channel is provided for the transfer of voice signals and data signals at the same time the side channel is transferring control information and/or additional data signals. The control information transferred on the side channel is used primarily for selecting the transfer of either voice signals or data signals on the main channel. By providing a separate and independent side channel for controlling the main channel, the inherent delays caused in the prior art design by switching between a voice transfer mode and a data transfer mode using a single channel are eliminated without redefining the bandwidth of the standard PSTN channel. <IMAGE>

IPC: H04N5/926
Filed: 1994-01-07
Abstract: A rotating converter, such as the helical scan unit used for magnetic tape recording, has a stator (18) and a rotor (13) winding. Signals from a source are processed and fed (16'-16") to a digital to analogue converter (19) coupled to the stator winding.  The signals are transferred inductively to the rotor winding and are converted (21) back into digital form for recovery at the outputs (11'-11"). The A/D conversion uses a clock regeneration process (22) based upon a phase locked loop.
