center core member is sandwiched by the first and second 
side core members with first and second magnetic films 
(4a, 4b) interposed between the center core member and 
the first and second side core members, respectively, and 
has a generally U-shaped cross-section tapering such 
that the width of the central core member measured at a 
level is larger at another level farther from the non-­
magnetic layer than at the first-mentioned level. The 
non-magnetic layer formed on the substrate serves to 
determine the dimensions and the arrangement of the gaps 
and cores for the double azimuth thin film magnetic head. 
In the method of manufacturing double azimuth thin film 
magnetic heads, at least one multi-level non-magnetic 
layer (5) is formed on a non-magnetic substrate (l) 
which non-magnetic layer serves to determine the 
dimentions and the arrangement of the cores and gaps, 
and then magnetic central core member and magnetic side 
core members sandwiching the central core member are 
 
 
formed on the multi-level non-magnetic layer with non-­
magnetic films interposed therebetween, thereby providing 
track widths and gaps for the head with a high accuracy. 
The cross-section of the center core member is formed to 
be generally U-shaped and taper as described above.

Title: Control circuit for frame synchronization at the receiving side
IPC: H04J3/06
Filed: 1986-11-11
Abstract: During the transmission of digital signals in time-division multiplex, a frame synchronisation must be carried out at the receiving end, in addition to the bit synchronisation, in order to be able to carry out an unambiguous distribution of the signal channels combined in the time-division multiplex frame. Depending on whether a terminal station in a point-to-point connection or a node carrying out switching tasks is involved, different boundary conditions can exist for carrying out the frame synchronisation. A control circuit (SSK) for carrying out the frame synchronisation for such a receiver is specified, which uses a synchronisation word detector (SWD), a variable divider (VT), a fixed divider (FT), a comparator (V), a synchronisation switch (SS) and a clock type selector (TU) and which can be easily adapted to the said different boundary conditions as a function of the setting of the clock type selector (TU). <IMAGE>

Abstract: An improved integrated circuit structure is dis­
closed comprising bipolar and/or MOS devices formed 
on the same substrate. Bipolar devices, when pres­
ent, have at least the emitter and the collector 
contact portions formed from a polysilicon layer 
which results in raised contacts. The MOS devices 
are similarly formed with raised gate contact por­
tions formed from the same polysilicon layer. 
Metal silicide is formed over at least a portion of 
the base, source, and drain regions to provide 
conductive paths to the base, source, and drain 
contacts. In one embodiment, the base, source, and 
drain contacts are also raised contacts formed from 
the same polysilicon layer to permit formation of a 
highly planarized structure with self-aligned con­
tacts formed by planarizing an insulating layer 
formed over the structure sufficiently to expose 
the upper surface of the contacts.
Patent EP-0232610-A3 (EP)
IPC: G01L1/10
Filed: 1986-12-11
Abstract: A sensor comprises a beam 1, e.g. of silicon, which 
resonates at a frequency dependent on the force imposed on 
the beam. Light on line 11 induces resonance of the beam 
1 by means of the photothermal effect. The light 
reflected from the beam 1 is amplitude modulated at the 
resonance frequency, and returns along line 11. It is 
reflected by semi-reflecting plane mirror 17 onto lens 19 
which focusses it onto photodetector 20. Photodetector 
20 produces an output voltage modulated at the 
oscillation frequency, and is thus representative of the 
force imposed on beam 1.

Abstract: Regelverfahren und Regelanordnung für einen Stom­
richterantrieb mit Gleichspannungs-Zwischenkreis. Das Re­
gelverfahren für einen Stromrichterantrieb kann bevorzugt 
bei Beschleunigungsantrieben eingesetzt werden, bei denen 
die in die Beschleunigung des Antriebs investierte Energie 
größtenteils während des Bremsens wieder zurückgeliefert 
wird. Zur Abstützung der dynamischen Leistung des 
Antriebes wird die Zwischenkreisspannung nicht konstant 
gehalten, sondern in Abhängigkeit der erfaßten Drehzahl (n) 
des Motors (14) derartig geregelt, daß sie mit fallender 
Drehzahl steigt und umgekehrt. Hierdurch wird erreicht, daß 
die starken Energiependelungen lediglich zwischen dem 
Zwischenkreiskondensator (6, 7) und dem Motor (14) stattfin­
den, jedoch nicht zwischen Netz und Zwischenkreiskonden­
sator. Es fließt ein nahezu konstanter Strom vom Netz zum 
Zwischenkreis (4), der lediglich die Verluste abdeckt. Es 
werden störende Netzrückwirkungen vermieden, ein günsti­
ger Leistungsfaktor erzielt und die Netzanschlußleistung 
reduziert.

Title: Computer workstation with interrupt signalling arrangement
IPC: G06F13/24
Filed: 1988-10-28
Abstract: A computer workstation including a processor, one or 
more input/output units, such as disk devices or network 
interfaces, a program memory and a video memory which 
contains video information displayed on a video monitor. An 
arbitration circuit selects among the processor and 
input/output units for transfers to and from the program 
memory and video memory. A master control circuit controls 
timing of transfers to and from the program and video 
memories, and periodically enables video update transfers of 
video information from the video memory to video control 
circuits, which control the video monitor. While a video 
update is in progress, the master control circuit holds off 
other transfer request of the processor and input/output 
units with the memory. The program memory stores interrupt 
vectors. In response to interrupt requests from units which 
require interrupt service, the master control circuit 
interrupts the processor. When the processor acknowledges 
the interrupt, the master control circuit enables the 
transfer from the memory to the processor of the interrupt 
vector associated with the highest priority interrupt.
