Schneidepegel (SP) überschreitenden Signalverläufen in den 
niederfrequenten Anteilen, sowie einer Impulserzeugungs­
stufe (13) zum Erzeugen eines Impulses beim Detektieren 
eines solchen, einem Synchronimpuls des ersten Synchron­
signals (Sy1) entsprechenden Signalverlaufs, wobei der 
Impuls eine kürzere Dauer aufweist als das kürzeste zweite 
Synchronsignal (Sy2), einen zweiten Signalverarbeitungs­
zweig (2) mit einem Halbwellendetektor (21) zum Abtrennen 
von Signalspitzen, die die Maxima (MaSy1) des ersten 
Synchronsignals (Sy1) überschreiten, aus dem Fernsehsignal 
und zum Umladen eines Signalspeichers (23) in einer ersten 
Richtung während eines der Dauer des zweiten Synchron­
signals (Sy2) entsprechenden Zeitbereichs, in dem die 
Signalspitzen auftreten, sowie einem dritten 
 
 
Signalverarbeitungszweig (3), in dem während eines 
Zeitintervalls, in dem entweder im ersten 
Signalverarbeitungszweig (1) ein Impuls abgegeben oder der 
Signalspeicher (23) in der ersten Richtung umgeladen ist,

Title: A pyroelectric infrared sensor and a method of manufacturing a dual pyroelectric element used therein
IPC: G01V8/20
Filed: 1989-04-10
Abstract: A pyroelectric infrared sensor includes a package (1) having a 
light-receiving window (26) and at least two dual pyroelectric elements 
(24,25) arranged in the package, each of the dual pyroelectric elements 
(24,25) having first and second unit pyroelectric elements 
(20a,20b;21a,21b), the first and second unit pyroelectric elements being 
connected in series or parallel with each other so as to have opposite 
polarities. The first and second light-receiving electrodes 
(14a,14b;15a,15b) and the first and second back electrodes 
(16a,16b;17a,17b) are formed such that an effective light-receiving 
electrode area of the first unit pyroelectric element (20b;21a) opposing 
a central portion of the light-receiving window (26) is smaller than an 
effective light-receiving electrode area of the second unit pyroelectric 
element (20a;21b) opposing a peripheral portion of the light-receiving 
window (26). A difference between secondary infrared rays incident on 
the first and second unit pyroelectric elements which is caused by a 
difference between angles of visibility of these elements with respect 
to the light-receiving window can be compensated. This invention also 
relates to a method of manufacturing the dual pyroelectric element.

Title: Angle of rotation detector
IPC: G01D5/243
Filed: 1991-05-10
Abstract: An angle of rotation detector has a drive unit which supplies 90 degree phase shifted signals to a pair of stator coils and measures an analog output from a rotor coil in a resolver. A calculating device calculates the rotational angle of the resolver using the output of an analog to digital converter receiving the analog output of the rotor. In one embodiment, the calculating device performs a Fourier transform to compute the phase of a fixed frequency component contained in the output of the rotor coil. In another embodiment, the drive unit supplies signals wherein f(T/2 + t) =-f(t) and the calculating device performs a Fourier transform using data from successive half periods of the drive waveform. In another embodiment, the output of the rotor is sampled at 1/4 period of an excitation signal from the drive unit and the calculating device determines the phase difference between the excitation signal and the rotor output. In still another embodiment, the calculating device compares the outputs at two or more points having a fixed time relationship and compares the result to stored reference data to arrive at the angle of rotation. <IMAGE>

Title: Method for aftertreating the focal track of rotary anodes of x-ray tubes
IPC: H01J9/14
Filed: 1992-05-04
Abstract: In a method of producing a rotary anode of an X-ray tube having a focal track region composed of refractory metals, the focal track region is manufactured by powder-metallurgy methods or by CVD OR PVD methods.

Abstract: A process is described for producing fibres from polymers which give off troublesome gases and/or vapours during spinning, comprising the steps of:   a) extruding the molten polymer through a spinneret (dies) into a closed spinning shaft (chimney, cell), b) quenching the resulting filaments in the spinning shaft with a gas,   c) withdrawing the resulting filaments from the spinning shaft, d) conducting the quench gas away from the spinning shaft and introducing it into a gas purification system and e) purifying the used quench gas by contact with an adsorbent for said troublesome gases and/or vapours.   It is possible by the present invention to keep hazardous gases occurring during the spinning of polymers away from the surroundings and to dispose of them. Suitable polymers are in particular polyphenylene sulphides. The invention further relates to an adapted apparatus for carrying out the process according to the invention. The apparatus comprises an extruder (1), a spinning pump (2) and a spin pack (3) which contains a filter (4) and spinnerets (5). The spinnerets (5) open out directly into a closed spinning shaft (6) which is provided with at least one feedline (7) and one discharge line (8) for the quench gas. In the representation of Figure 1, two discharge lines (8) for the quench gas are depicted at the top and bottom end of the spinning shaft. In addition, in this Figure 1, an auxiliary extraction line (12) is furnished for the quench gas which is mounted at the bottom end of the spinning shaft next to the outlet orifice for the filaments. In the representation of Figure 1, all discharge lines for the quench gas are equipped with a gas purification system (9). <IMAGE>
