Patent EP-0038048-A3 (EP)
IPC: G03G15/04
Filed: 1981-04-10
Abstract: A light scanning assembly for electrophotographic 
printing plate making apparatus of the type which com­
prises an enclosure which houses a copyboard, an opti­
cal train and a carriage. The carriage moves in a horizon­
tal path beneath a platen carrying a sheet of electro­
photographic material. The carriage has a corona device, 
a slit, a toning device, including an electrical develop­
ment electrode or bias plate and means for withdrawing 
excess toner from the electrophotographic sheet after 
toning. The copyboard is loaded in horizontal position 
and moved along a guide track to a vertical position. 
When the copyboard is vertically oriented, the light 
scanning assembly is translated across the face of the 
copyboard in synchronism with the movement of the 
carriage to project the pattern on the copyboard hori­
zontally through an optical train from hence it is deviated 
upward to cooperate with the slit.  
     The light scanning assembly comprises a support 
bracket mounting a pair of illuminating lamps disposed 
spaced one above the other respectively each with an 
associated elliptically configured reflector, whereby the 
light from each lamp is directed to a common band 
location across the face of the copyboard. The support 
bracket is driven, for translation of the lamp pair and 
their common band, across the face of the copyboard 
synchronously with the movement of the carriage. The 
light scanning assembly further includes an additional 
illuminating lamp mounted with its associated reflector 
on a second bracket secured to the first bracket for 
movement therewith but, pivotally coupled thereto for 
independent rotation across the surface of the copy­
board. This additional lamp is energized only when a 
transparent master or original is carried by the copyboard 
and the first pair of lamps are not energized. The second 
bracket is pivotable to rotate said additional lamp and 
associated reflector along a predetermined arc during 
the vertical translation thereof so that the light emitted 
therefrom is focused along a straight line continuously 
directed to the center of the optical train so that the 
image always is in focus. A cam wheel on the bracket 
follows a canted or tapered guide surface formed on a 
vertically arranged leg supporting said light scanning 
assembly to effect pivoting of the said bracket, return 
of the bracket being effected solely by gravity.

Patent EP-0054935-A3 (EP)
IPC: G05D3/12
Filed: 1981-12-18
Abstract: An electronic control system for a machine tool 
employs a monitoring system for monitoring the absolute 
position of a reversibly (and linearly or rotationally) 
movable moving member in the machine tool. The moni­
toring system includes a clock, a digital feedback posi­
tion counter having a predetermined count range, an ex­
citer, a feedback device responsive to movement of the 
movable member, a digital position storage device, a 
zero crossing detector, and a zero position counter. The 
feedback position counter, which operates at a clock 
frequency, controls the exciter which provides a pulsed 
exciter signal to the feedback device. The feedback 
position counter also provides a position count Nc to 
the position storage device and to the zero position 
counter. The feedback device provides, through a zero 
crossing detector, a pulsed feedback signal to the posi­
tion storage device (and to the zero position counter) 
and the phase shift between the exciter signal and 
feedback signal is linearly related to the displacement 
of the moving member. The position storage device 
provides a continuously updated position number Np 
which is also linearly related to member displacement, 
i.e., the position of the member, The zero position counter 
typically comprised of a synchronous 4-bit bi-directional 
binary counter provides a zero position count Nz to the 
representative of the net number of times the position 
number Np passes through zero between consecutive 
samples. A computer, coupled to the position storage 
device and to the zero position counter, processes the 
position number Np and the zero position number to 
unambiguously determine the speed of the moving mem­
ber.

Patent EP-0105130-A3 (EP)
Title: Writing beam focus monitor
IPC: G11B7/09
Filed: 1983-08-04
Abstract: The present invention relates to a method and means for monitoring the focussing condition of the writing light beam impinging the writing surface of a recording medium. Systems for monitoring the focus condition of a light beam used in reproducing prerecorded information from a videodisc by a videodisc player operate by splitting off reflected light from the incident light beam path in a region where the incident beam is diverging. In this manner, the reflected beam entering the polarizing cube, placed in the diverging portion of the incident beam, produces a converging light beam diverted to the photodetector. Because of numerous problems in attempting to apply player concepts to writing machine, it has been common practice in the prior art of recording laser discs to periodically determine optimum focussing position for the various optical elements affecting focus by producing a series of test discs and playing back each disc or portion thereof corresponding to a particular combination of settings for the various optical parameters such as power and focus involved. The empirically derived conditions necessary to produce acceptable focussing conditions, however, are extremely costly due to the labor time involved in setting up and determining the optimum focus conditions as well as in the loss of videodisc production due to down time of the mastering machine. The present invention operates on the recognition of the fact that, although for all practical purposes a light beam from a laser device is collimated, it, in fact, is very slightly divergent as it emerges from the laser resulting from diffraction of the Gaussian intensity profile plane wave that exists between the laser resonator mirrors at the beam waist and from refraction as the output light traverses the thickness of the output mirror. Accordingly, since the beam exiting the laser tube is slightly divergent, the reflected light from the videodisc, even though a small in intensity, is conversely (provided the system is in focus) convergent as it passes in reverse direction through the diverging lens and on toward the output of the laser device and beyond to the conjugate point where it forms a real image of the source plane wave, thus eliminating the need for a relay lens. The present invention makes use of this slight divergence and convergence of the incident and reflected beams, respectively, at the exit end of the modulator to effect monitoring of the focus condition of the writing beam.
