Patent EP-0801449-A2 (EP)
Inventor: BRUESSELBACH HANS
IPC: H01S3/0941
Filed: 1997-04-09
Abstract: A high-Q pump cavity (14) is formed from undoped crystal pieces (12) that are diffusion bonded to a doped core (10) of the same crystal host material. The resulting monolithic pump cavity (14) has 2 opposing convex-curved sides (22, 24) which have a highly-reflective coating (26) on their outer surfaces, except in narrow slit-shaped areas (28) on each curved side (22, 24) through which laser-diode-supplied pump light (54) enters the cavity (14). The curvature of the two curved sides (22, 24) is such that nearly all the pump light rays (54) that pass through the slit-shaped areas (28) are deflected by the curvature through the doped core (10), and rays that enter the cavity (14) are redirected through the doped core (10) many times, resulting in efficient, uniform absorption. The cavity (14) has two opposing flat sides (58, 59) that interface with metal heat sink blocks (76, 78) to facilitate the removal of internally-generated heat. Thermally induced astigmatic lensing caused by this heat is countered by a cavity design in which the core shape and the dimensions of the cavity (14) minimize this astigmatism. Embedding a doped crystal core (10) within a crystal (12) of the same material allows the lasing mode size to be larger than the core (10), allowing the entire doped core (10) to be accessible for efficient extraction, helps reduce parasitic oscillation, and provides highly effective cooling. Furthermore, laser diode light (44, 46; 100, 102) couples directly into the doped core (10), with close to 100 % transport efficiency.

Abstract: Highly concentrated waste water is subjected to a partially aerobic method in the reaction chamber of a vertical reactor (1). Aeration of the waste water is performed by regulating the redox potential. To this end, means (14) for measuring the pH value, on the one hand, and means (15) for measuring the redox potential value of the treated waste water, on the other hand, are arranged in a bypass line. The process computer acts via a regulator (31) on a regulating member (19) which regulates the supplied amount of air, and regulates the redox potential value according to the measured pH values in accordance with a predetermined relationship stored in a memory device (33). By means of regulating the redox potential by guiding the pH value, an essentially constant high rate of decomposition of 90% COD is achieved.

Abstract: Disclosed is a digital audio recording and/or reproducing system for a digital recording medium, in which the audio signal sampled according to a new recording method can be reproduced in an audio device having a sampling frequency in accordance with an existing recording method. The recording and/or reproduction system comprises a reference unit former (10) for receiving a pulse-code-modulated digital audio signal and forming a reference unit sequence each reference unit having a predetermined size from the received digital audio signal. A formatting unit (20) formats the reference unit sequence into a recording unit sequence in which at least one recording unit has at least one data block among an odd-numbered data block and an even-numbered data block which exist in at least one reference unit, and inserts additional data to produce a formatted data. A recording unit (30) records the formatted data on a digital recording medium. A reader reads the formatted data from the digital recording medium and discriminates a sampling frequency of the digital audio signal contained in the formatted data. An inverse formatting unit inversely formats the formatted data in the form that enables the data to be digital-to-analog-converted by a digital-to-analog converter and signal-processes the inversely formatted data, based on comparison between the discriminated sampling frequency and the operating frequency of the D/A converter.

Abstract: The present invention is directed to a precise method of registering a plurality of ROS
imagers (102, 104, 106, 108), so as to form sequential registered images (l 1 , l 2 , l 3 , l 4 ) on a
photoreceptor belt (14) in a single pass. Pairs of belt holes (126, 128, 130, 132, 134, 136, 138, 140)
are formed in the photoreceptor belt (14), outside the image area and scan lines (40A, 40B, 40C,
40D) of the ROS imagers (102, 104, 106, 108). A pair of light sources (144, 146) are incorporated
into the post polygon optics (41) of each ROS imager (102, 104, 106, 108) so as to produce a light
spot at the photoreceptor belt (14) which will periodically illuminate the holes (126, 128, 130, 132,
134, 136, 138, 140) therein. As the leading edge of the belt holes (126, 128, 130, 132, 134, 136,
138, 140) advances into beams from the light sources (144, 146), detectors (110, 112, 114, 116, 118,
120, 122, 124) placed beneath the belt (14) and beneath the exposure station provide signals
representing the exposure level of the light source output. The position of a transmissive optical
element (42) with no optical power, subsequent to each of said ROS imagers (102, 104, 106, 108), is
adjusted in response to registration error signals generated by said detectors (110, 112, 114, 116,
118, 120, 122, 124) to adjust the position of said scan lines (40A, 40B, 40C,) 40D).

Abstract: Database query and response messages traversing signalling links in an SS7
signalling system, to enable local number portability (LNP) to be implemented, are passively
monitored by a verification system. This verification system has its own copy of the LNP
database, which it interrogates with information contained in a monitored query message.
The system compares the results of this interrogation with the contents of the monitored
response message corresponding to the query message. Any discrepancy indicates a
potential problem with the LNP database.

Abstract: Disclosed is an integrated pass-transistor logic circuit
which includes a conditional sum adder. This sum adder has
seven sum generation blocks of module form and two carry
generation blocks. With the sum adder, before carry
propagation which is generated through multiplexer chain in
respective sum generation blocks arrives at the final stage
of the multiplexer chain, the final stage is driven by
block carry signals BC i  and    BC i      provided from the respective
carry generation blocks. The carry generation and the sum
generation occur individually in the conditional sum adder.
The sum generation blocks are constituted with pass-transistor
logic and the carry generation blocks with CMOS
logic, the sum adder has a faster operation speed and a
lower power dissipation, as compared with the prior art
conditional sum adder having either the pass-transistor
logic or the CMOS logic.

Abstract: The object of the invention is a transmitter/receiver for transmitting and receiving of an RF signal in two frequency bands. In the solution according to the invention, a transmitter/receiver is used which is based on direct conversion and in it, when operating in both frequency bands, the mixing frequency is formed by means of the same synthesizer (340). This is implemented preferably in such a way that in the higher operating frequency, the frequency of the output signal of the synthesizer is used as such as a mixing frequency and when operating in the lower operating frequency, a mixing frequency is used which is obtained by dividing the frequency of the output signal of the synthesizer by two or a larger integer in the divider (311, 361). When the solution according to the invention is used, many synthesizers are not needed in the transmitter/receiver and no intermediate frequency components are needed.

Abstract: A low noise fan (1) reduces the production of turbulent
vortices created by the passage of the fan's blade (3)
tips through the air by providing an annular venturi (4)
that is attached at its inner surface to the blade tips,
and that thus rotates with those blades as a unit. This
prevent high pressure air at the blade tips from spilling
into low pressure air. The outer surface of the rotating
venturi may have a close fit against the inner surface of
an outer annular stationary housing (14) of the fan, to
minimize any acoustic or mechanical mischief created by
the otherwise exposed outer surface of the rotating
venturi (4).

Abstract: A distribution of the concentration of initial point-defects
(11) which generate in an ion implanting process
is obtained with an ion implanting simulator. As a local
function of the distribution, the distribution of the intensity
of absorption (12) of point-defects is obtained.
A term of absorption of point-defects obtained from the
distribution of the intensity is included in a diffusion
equation. With the resultant diffusion equation, the
diffusion simulation is performed. Thus the simulation
using the diffusion equation may be extended to two or
three dimension and cope with various ion implanting conditions.
