Abstract: A television line output circuit comprises a first sawtooth 
network with a diode (D), a trace capacitor (Ct), a retrace 
capacitor (Cr) and a line deflection coil (Ly), and a second 
sawtooth network with a diode (D′), a trace capacitor (C′t), a 
retrace capacitor (C′r) and a coil (L′). The diodes (D, D′) are 
connected in series and the two sawtooth networks connected across a 
line output transistor (Tr). A first modulation source (M1) is 
connected across the trace capacitor (C′t) in the second sawtooth 
network to modulate the line deflection current to overcome 
East-West pin-cushion distortion.  
     A resistor (R) of low ohmic value is connected between the 
anode of the diode (D′) in the second sawtooth network and earth and 
a second modulation source (M2) is connected across this resistor 
(R). The second modulation source (M2) provides a signal dependent 
on beam current to correct for display errors at line frequency rate 
as they occur.

Abstract: A data processing system including a processor that executes a 
plurality of instructions including at least one instruction that 
requires an external operation to be performed. The processor provides 
information for this external operation instruction to an external device 
and continues to execute instructions that do not require the results 
from this external operation. The external device receives the 
information from the processor, performs the external operation and 
provides the results to the processor. A further aspect of this data 
processing system is an interface that is interconnected between the 
processor and the external device. The processor provides the external 
operation information to the interface. The interface in turn provides 
the information to the external device and concurrently accesses data 
from the memory that will be required by the external device for 
performing the external operation.

Title: Incremental length or angle measuring device
IPC: G01D5/36
Filed: 1988-05-20
Abstract: In this device, two parallel incremental tracks (5, 6), which are offset with respect to one another by T/4, of the same incremental period T are arranged on a scale (1) on both sides of a reference marker (7). Along the scale (1), a scanning unit with a scanning plate (2) is conducted which also has an incremental division with the incremental period T, both incremental tracks (5, 6) and the reference marker (7) being scanned with this increment by photodetectors (12, 13, 14) located in one line below one another. Due to the symmetric arrangement of the incremental tracks (5, 6) relative to the reference marker (7), the required relation between the reference pulse (UR, URF) and the counting signals which are obtained from the analog scanning signals of the incremental tracks (5, 6) is retained even when the scanning plate (2) is tilted relative to the scale (Figure 1). <IMAGE>

Patent EP-0313216-A3 (EP)
Title: Optical transform system
IPC: G05B19/4097
Filed: 1988-09-21
Abstract: Method and apparatus for generating compound shapes in optical surfaces 
needed to accommodate variable magnification, off-axis projection, reflection 
from diverse surfaces, reflector relay, intensity pattern requirements and other 
complex optical transform functions. The present invention finds particular 
application in automotive rearview mirrors (either inside or outside mounted) 
where it is desired to view wide angles and in automotive headlights where it is 
desired to illuminate specified targets with a desired or required intensity pattern. 
The present invention permits the realization of mirrors of such capability by 
providing a variable magnification mirror. The surface generation capabilities 
permit controlled magnification changes that nevertheless are still image forming 
and typically avoid the human eye focussing difficulties normally associated with 
variable magnification mirrors. The present invention includes a computer driven 
reflector, design system which permits the designer to see the field of view, ray 
tracings, reflected beam intensity pattern and other data pertinent to a variable 
magnification mirror from entered mirror specifications. The effect of changes in 
specifications can be rapidly determined and a final design achieved through one or 
more such reiterations. The system further determines machine tool motional 
controls for grinding a surface corresponding to the entered mirror specifications. 
A machining center having a high speed bit, a EDM tip and capable of producing 
the surface with optical quality precision is a further part of the invention. The 
 
 
capability of the invention in producing irregular optical shapes for these 
applications is utilized for the production of mirrors that accomplish complex 
focussing functions for use in off-axis projection mirrors, relay mirrors, and 
headlamp reflector mirrors. According to the invention, optical systems capable of 
accomplishing such complex focussing can be realized with a single reflector.

orientations of the platform either along the longitudinal 
or transverse axis of the platform. When the angle sense 
means signals are interpreted by the circuit means 
appropriate hoist control signals stop the travel of 
the platform for a pre-determined period, control the 
hoists to bring the lowest portion of the platform up 
into a substantially level position, stop the travel 
of the platform for a pre-determined period and recommence 
the direction of travel of the platform.

Title: Semiconductor circuit having an excess voltage protection circuit
IPC: H02H7/20
Filed: 1989-12-11
Abstract: A semiconductor circuit has d.c. supply lines 
(10/13,11/14) and an excess voltage protection 
circuit. The protection circuit comprises a 
switching transistor (T1) connected in series with 
one of the supply lines (10/13), a control circuit 
(15) which is responsive to a voltage detector 
circuit (16), coupled with the supply line (10/13), 
and which is effective to trigger the switching 
transistor T1 to a non conductive state upon 
detection of an excess voltage. The voltage 
detector circuit comprises a semiconductor element 
(T8), having a voltage breakdown characteristic 
correlated with one or more of the remainder of the 
semiconductor elements (T10). The semiconductor 
element (T8) is adapted to be driven to breakdown in 
response to a voltage across the supply lines 
(10/13,11/14) less than that which will cause 
breakdown of said one or more of the remainder of 
the semiconductor elements T10. The increased 
current drawn by the element (T8) at the onset of 
breakdown is effective to cause the control circuit 
(15) to trigger the switching transistor (T1) to its 
non conductive state.
