Title: Optical arrangement for the line-wise illumination of scanned originals
IPC: H04N1/12
Filed: 1987-04-28
Abstract: An opto-electronic arrangement for line-by-line scanning of color originals in reproduction technology by means of photodiodes as the opto-electronic transducers characterized by a light source with a condenser system whose light is projected at a fiber-optical shape converter, whose output cross section forms a linear optical pattern which is focussed further by a cylindrical lens into a band shape onto the original. In one embodiment, a filter wheel is provided between the light source and shape converter and in another embodiment the photodiodes are provided with dichroitic filters for selecting the color of the light received from the original into desired colored patterns. In another modification, the first cylindrical lens focusses the light onto a diffusing element and then a second cylindrical lens is present for focussing the light from the diffusing element directly onto the original. The light from the original is preferably received either by a macrolens and focussed onto the row of photodiodes or is received by a GRIN fiber optical arrangement for directing the light onto the photodiodes.

Patent EP-0262452-A3 (EP)
IPC: G06F12/16
Filed: 1987-09-04
Abstract: A memory device for storing data and providing address and 
data line error detection is disclosed. A memory (12) holds 
two copies of data, each copy of data having opposite parity 
dependent on its address. An address sequencer (13) 
provides addresses to the memory. The addresses are modified 
to select the copy of data in the memory having a 
predetermined first parity. A parity checker (22) checks 
the parity of data provided by the memory and provides an 
error indication if the parity is incorrect, said error 
indication being indicative of address and data line errors 
and memory cell errors. When an error is indicated by an 
error latch (26), the error causes a retry of the memory in 
the location where the desired data is stored with parity 
opposite the first parity.

IPC: H01L21/18
Filed: 1987-09-08
Abstract: The present invention discloses a crystal pulling 
apparatus having a double-crucible structure, charac­
terized in that an inner crucible is located in an outer 
crucible. An end of a pipe-like passage (14) is located 
in a through hole (13) formed in a side wall of an inner 
crucible (12) located in an outer crucible (11), and a 
melt is supplied from the outer crucible (11) to the 
inner crucible (12) through the pipe-like passage (14), 
during crystal pulling. During melting or neckdown, 
prior to crystal pulling, diffusion of an impurity be­
tween the melts in the outer crucible (11) and the 
inner crucible (12), and exchange of the melts between 
the outer crucible (11) and the inner crucible (11) are 
prevented by the pipe-like passage (14).

Abstract: Apparatus for analyzing particles contained in a fluent 
medium (12). The apparatus includes a body (20) having a window (30), an optical 
source preferably comprising a laser diode (100) having a small light emitting 
area (140), and an optical system (102) for focusing the light from the laser diode 
at a focal spot (84) such that the size of the focal spot is approximately equal to 
the size of the light emitting area of the laser diode. A photodetector (106) is 
mounted in the body and detects light backscattered from the focal spot by 
particles in the fluent medium, and produces an electrical signal that comprises 
a series of pulses associated with the particles. The electrical signal is input to 
a detector that counts the pulses and indicates the number of particles in the 
fluent medium. The detector includes discrimination means for preventing the 
counting of a pulse that has a rise or fall time above a predetermined threshold, 
thereby discriminating against particles that are not at the focal spot. Means 
are provided for measuring the integrated amplitude of the electrical signal, and 
for varying the distance between the focal spot and the window to maximize 
such integrated amplitude.

IPC: F15B9/09
Filed: 1987-06-12
Abstract: A parallel redundant actuator system of the kind wherein the 
signal in each of a plurality of lanes (31A, 31B, 31C) comprises the 
difference between a demand signal and a signal indicating the 
position of an output member of the system and the output member (3) 
takes up a position determined by the output of a summing arrangement 
(21) for the outputs of the lanes and wherein between the input of 
each lane and the output of the summing arrangement each lane has a 
non-linear input/output characteristic whose slope over a range of 
values of input in which changes of input due to failure of another 
lane occur is greater than if the characteristic were linear over the 
range of values of input over which the lane is capable of operation. 
The arrangement is intended to reduce the change in position of the 
output member which occurs on failure of a lane.

Title: Printer sheet feed system
IPC: B65H5/36
Filed: 1989-08-04
Abstract: A print medium sheet feeding system for an ink jet prin­
ter having a print head with a planar array of jets is 
provided by clamping the leading edge of a paper sheet 
after it is passed through a printing zone to a rotating 
assembly of parallel disks. The sheet is pulled through 
the printing zone by rotating a plurality of disks (14) 
with a clamp (50) being carried with the rotating drum 
(14c) formed by said disks (14). A platen (92) is pro­
vided which has a flat surface in the printing zone (56) 
forming a tangent to the outer surface of the rotating 
disks (14). The sheet is initially clamped against the 
drum (14c) by the combination of a lever arm (80) which 
is selectively engageable with the drum for rotation 
therewith and an attached actuating arm (72) having a 
plate (52) which secures a sheet to the drum surface. 
The resulting clamp (50) rotates with the drum (14c) 
until the sheet passes below idler rollers which are 
biased against the drum surface. These rollers then hold 
the sheet against the drum for motion of the sheet with 
the drum surface. The actuating arm is released from the 
drum after a sheer passes below the rollers, thereby 
allowing any sized sheet to be fed through the system.

Filed: 1989-11-06
Abstract: A P-bar excitation system employs a generator (56) 
having means (58) for adjusting the voltage or the voltage 
and current available from the P-bars. The voltage and 
current are adjusted using paired P-bars (42′, 62; 44′, 64; 
46′, 66) per phase, wherein each pair of P-bars is 
connected in series and are angularly displaced from each 
other about the inner circumference of the armature to 
attain a vector sum of voltages yielding the desired 
voltage per phase (Fig 5). Optionally, the generator 
magnetic flux or equivalently, the number of armature 
turns may be adjusted to yield the desired P-bar voltage 
and current. In one embodiment (Fig. 6) the direct output 
of the P-bars is connected directly to the rectifier and 
control circuit (20) for development of DC excitation 
power. This permits elimination of the excitation 
transformer (34) and overall simplification of the 
excitation system.
