bündel (6) auf, das mit seinem Eintrittsende bei der Licht­
quelle (2) und mit seinem Austrittsende mit einzelnen

Einstrahlung in die einzelnen Faserstränge. Austrittsseitig 
läßt sich der Lichtaustrittswinkel für jeden Lichtpunkt 
einzeln verstellen, so daß hier Intensitätsunterschiede auf 
einfache Weise nochmals ausgeglichen werden können.

Title: Position detector employing a sector fresnel zone plate
IPC: G03F9/00
Filed: 1989-08-01
Abstract: A position detector for use with an X-ray exposure 
apparatus and the like includes sector Fresnel zone plates 
(SFZP) which are provided on a mask (14) and a wafer (15) minutely 
spaced in position in the direction of the optical axis 
of an exposure X-ray, as alignment marks (16, 17). A laser ray of 
at least one wavelength is applied to the surfaces 
of the SFZPs at an angle with respect to the surfaces. 
The SFZPs are designed such that the principal focal 
planes of Fresnel diffraction images of the SFZPs to a 
single wavelength laser ray agree with each other. 
In the case of illumination rays of a plurality of 
wavelengths, an objective lens (9) is provided in a detection 
optical system (10) which objective has such an axial chromatic 
aberration that focal planes of the objective lens to 
the plural wavelength rays agree with respective Fresnel 
diffraction focal planes of the SFZPs to the rays. 
The image formed on the superposed focal plane of the 
objective lens is converted into an electric signal, 
which is handled to detect a relative position between 
the mask and wafer in the direction perpendicular to 
the surface thereof.

Title: Coherent psk demodulator using bit error rate and s/n ratio to establish synchronization
IPC: H04L27/00
Filed: 1989-11-14
Abstract: In a coherent M-ary PSK demodulator, an M-ary PSK detector (1) 
demodulates a received M-ary PSK modulated convolutional code with a 
carrier recovered by a voltage-controlled oscillator to produce first and 
second channels of demodulated convolutional codes. A convolutional 
decoder (7) decodes the signals of the first and second channels while 
correcting bit errors. An error rate detector is provided for detecting when 
the number of such errors occurring during a specified period of time is 
smaller than a predetermined value and generates a signal indicating that 
the convolutional decoder (7) is synchronized with the demodulated signals. 
The power levels of signal and noise components of the demodulated 
channels are detected by a power detector (11). In a frequency control circuit, a 
series of VCO control signals of a different value are generated as 
candidates for precise synchronization in response to the signal from the 
error rate detector in order to synchronize the PSK detector (1) successively at 
the candidate frequencies, and signal-to-noise ratios are successively 
derived from the outputs of the power detector (11). A maximum value of the 
derived signal-to-noise ratios is then detected and one of the candidate 
VCO control signals which corresponds to the detected maximum signal-­
to-noise ratio is adopted as a valid VCO control signal.

Patent EP-0338655-A3 (EP)
IPC: H03M1/00
Filed: 1989-01-26
Abstract: Integral linearity error in the operating 
characteristics of an analog to digital converter 
employing sampling comparators (12) is reduced by 
generating a further error in a sense to offset said 
linearity error at least in part. This is achieved, in a 
preferred embodiment, by recurrently connecting (31) at 
least one resistive shunt (28) across a predetermined 
central portion of a reference voltage divider input (22) 
to the comparators. The shunt resistance is 
approximately an order of magnitude larger than the 
resistance of the shunted part of the divider. Each 
recurrent connection interval is of fixed duration 
independent of sampling rate, and each interval spans the 
beginning of a recurrent time of connection of said 
divider to said comparators.

Title: Electronic mail systems
IPC: G06Q10/00
Filed: 1989-10-23
Abstract: A method is disclosed for confirming selected activities of multiple 
electronic mail recipients. An indication of each item of electronic 
mail designated by a sender as requiring confirmation of the 
recipient's activities is stored within a confirmation log. The 
activities of each recipient are then monitored and a confirmation 
message is generated automatically in response to a determination that 
confirmation is required for a selected activity or recipient. Each 
confirmation message is then correlated with the stored indications of 
electronic mail objects within the confirmation log. Thereafter, the 
sender may display the contents of the confirmation log selectively by 
mail object or recipient to determine the status of multiple selected 
electronic mail objects. A notification of the receipt of a 
confirmation message may also be transmitted to the sender.

Title: Data processing system wherein a simple peripheral control arrangement enables a cpu to access an enlarged address area
IPC: G06F12/06
Filed: 1989-10-26
Abstract: A data processing system comprises a central 
processing unit (10) for producing an output address 
signal and a read-only memory (20) for receiving an 
input address signal which is equal to the output 
address signal except for a preselected one bit. The 
read-only memory is one of peripheral units (20, 30, and 
40). Responsive to the output address signal, an 
address decoder (50) selects one of the peripheral units 
as a selected peripheral unit. The central processing 
unit produces an address selection control bit in 
addition to the output address signal. A bit holding 
circuit (60) holds the address selection control bit as 
a held control bit. Responsive to the held control bit, 
a gate circuit (70) processes the preselected one bit 
into a processed bit. The processed bit is supplied to 
the read-only memory through a connection line (27) in 
place of the selected one bit.
