Abstract: A steering angle middle point detecting apparatus of 
the invention is provided with a vehicle speed (18) sensor for 
detecting vehicle speed, a torque sensor (6) for detecting at 
regular intervals steering torque to be added to a steering 
wheel, a steering position detecting (17) means for detecting a 
steering position of a steering mechanism, a means for comparing 
a steering torque set value previously set corresponding

point calculating means for calculating a middle point of a 
steering angle by using the steering position of the steering 
mechanism detected by the steering position detecting 
means (17) when the steering torque is smaller than the steering 
torque set value, which judges that the vehicle goes 
straight when the detected steering torque is smaller than 
the steering torque set value corresponding to the vehicle

the middle point of the steering angle. Further, a steering 
angle middle point detecting apparatus of another invention 
is added, a judgment of an angle velocity of the steering 
angle, that is, a rotational speed of the steering wheel or 
variation of the steering torque, judges that the vehicle 
goes straight when it is at the specified value or less, and 
judges the steering position at that time to be the middle 
point of the steering angle.

Title: Process for defining an array of pixels in a thin film electroluminescent edge emitter structure
IPC: H05B33/10
Filed: 1989-10-05
Abstract: A method for defining an array of light-emitting 
pixels in a thin film electroluminescent edge emitter 
structure includes the steps of moving the structure in 
proximity to a stationary first laser source as the first 
laser source is operated to generate a plurality of first 
laser pulses. The plurality of first laser pulses are 
focused into "lines" of light energy that strike the 
structure at a plurality of spaced apart locations in 
succession to ablate a predetermined number of layers of 
the structure. This ablation process forms a plurality of 
spaced apart channels in the structure. The portions of 
the structure remaining between each pair of adjacent 
channels define an array of pixels in the structure. The 
structure having the pixels formed therein is moved in 
proximity to a second laser source. The second laser 
source is movable in a selected direction substantially 
perpendicular to the direction of movement of the struc­
ture. The second laser source provides a second laser beam 
that is focused to a "point" of light energy which strikes 
the end portion of each pixel at an area inward of the 
pixel edge surface to ablate a predetermined number of 
layers at each pixel end portion. The movement of the 
second laser beam is controlled relative to the movement of 
the structure to correspondingly control the amount of 
material ablated inward of the edge surface of each pixel 
to remove the pixel edge surface and form a new pixel edge 
surface shaped to a preselected contour.
Patent EP-0372825-A3 (EP)
Title: Monolithic sampler
IPC: G01R13/34
Filed: 1989-11-30
Abstract: A Monolithic Sampler is disclosed. The present invention overcomes 
the problem of inadequately low sampling rates that result from circuit designs 
or component limitations that constrain the bandwidths of previous instruments.  
     The sampler includes five circuit stages: a local oscillator section that 
may be used to drive the system, a shock wave generator that produces high 
frequency edge-sharpened pulses, a reflection damping clamping section, a delay 
section, and a sampler section regulated by the stream of shock waves which 
produces an IF output. The local oscillator or a pulse generator (not shown) 
produces an input that propagates down a nonlinear transmission line. Once 
this input reaches the shock wave generator section, it encounters a series of 
hyperabrupt diodes which are employed as voltage dependent capacitors called 
varactors. These varactors deform the input pulses and generate a stream of 
spike-shaped waveforms known as shock waves. The shock waves successively 
energize sampling diodes in the sampling section of the circuit. When these 
diodes are energized, they open pathways from an RF input to sampling 
capacitors which charge up with small representative bits of current from the 
input. A sample or snapshot of the input is drawn from these capacitors through 
an IF output coupling network. The clamping and delay sections of the sampler 
minimize spurious ringing throughout the circuit and manage the timing of the 
oscillation of these reflections.  
     The entire sampler is monolithically integrated on a single substrate 
using conventional semiconductor fabrication and packaging techniques. The 
resulting Monolithic Sampler is a highly efficient instrument which is extremely 
reliable and easy to manufacture. The integrated structure reduces unwanted 
interference and eliminates the need for costly fabrication methods which require 
expensive tools that ensure the precise mechanical alignment of discrete 
components. The utilization of the hyperabrupt diode loaded transmission line 
 
 
in this novel design enables the sampler to operate at frequencies exceeding 100 
GHz. The Monolithic Sampler disclosed and claimed in this patent application 
provides an advanced and highly useful instrument that will enable engineers in 
the electronics industry to construct more cost-effective and powerful diagnostic 
and monitoring systems.
Patent EP-0358593-A3 (EP)
IPC: H01L33/00
Filed: 1989-09-08
Abstract: An optical light source (12) is interfaced to an 
optical fiber (20) by mounting the optical light source on a 
source carrier (14), mounting the optical fiber on a fiber 
carrier (18), aligning the optical fiber with the optical 
light source and bonding the source carrier to the 
fiber carrier thereby securing the alignment of the 
optical fiber and the optical light source. The fiber 
carrier can be made to have the same or substantially 
the same thermal expansion characteristics of those of 
said source carrier. A lens may be interposed between 
the light source and the fiber, typically by forming a 
convex surface on the tip of the fiber. The apparatus 
so made thus comprises an optical fiber carrier, an 
optical fiber attached to the fiber carrier, a source 
carrier and an optical light source mounted on the 
source carrier aligned with the optical fiber. A lens 
may be provided between the source and the fiber, 
typically formed on the tip of the fiber. For both 
method and apparatus, separate source and fiber 
carriers may be dispensed with and a single carrier 
used for both source and fiber.
