Patent EP-0139946-A3 (EP)
IPC: G11C11/34
Filed: 1984-08-13
Abstract: Halbleiter-Bauelement mit einem Heiße-Elektronen-­
Transistor des Tunnelemissionstyps, der eine Emitter­
schicht, eine Isolatorschicht, eine metallische oder metallisch 
leitende Basisschicht und eine Kollektorschicht aufweist. 
Angestrebt wird eine Ausgstaltung des Bauelements, die in 
einfacher Weise hergestellt werden kann. Das wird dadurch 
erreicht, daß die Emitterschicht aus einer Inversionsschicht 
(16) besteht, die im Kanalbereich (4) eines auf einem Halb­
leiterkörper integrierten Feldeffekttransistors zwischen 
dessen Source- und Draingebiet (2, 3) aufgebaut ist, wobei die 
Basisschicht (5) wenigstens einen Teil der Gateelektrode des 
Feldeffekttransistors darstellt. Der Anwendungsbereich 
umfaßt hochintegrierte Schaltkreise.
Patent EP-0135908-A3 (EP)
IPC: A61B6/00
Filed: 1984-09-18
Abstract: In a digital fluoroscopy apparatus (100), digital refer­
ence data is written in a given data position of digital image 
data where no medical information is contained. This digital 
reference data has contrast level information with respect 
to X-ray images of an object (1) under examination. The 
image data having the reference data is stored in an ana­
logue storage device (22) after being D/A-converted. When 
the image signal having the D/A-converted reference data 
is again A/D-converted for the digital subtraction, the con­
trast level of the finally-A/D-converted reference data va­
ries from that of the original reference data. The image data 
having the finally-A/D-converted reference data is correct­
ed based upon the contrast level variation from the original 
level in an image data correction unit (29).

IPC: E21B47/18
Filed: 1984-10-23
Abstract: An improved acoustic signal generator has rotor and stator 
elements, each having a plurality of radially-extending lobes 
and intervening ports relatively positioned and configured to 
establish fluid dynamic forces that bias the generator into an 
open position, thereby imparting a «stable open» characteristic 
to the generator. The rotor is located downstream of the stator, 
and rotor lobes are outwardly tapered in the downstream 
direction and have underlap relative to the upstream stator 
lobes. The invention is especially suited for use in oil industry 
MWD operations to communicate downhole measurement 
data to a well surface during drilling. In one embodiment, 
undercuts on the rotor lobes impart a flutter action which 
clears debris.

IPC: A46B3/06
Filed: 1985-01-19
Abstract: In a method for connecting bristles to a bristle carrier, each of which is made of thermoplastic material, at least the ends of the bristles are heated so that a reversal of the molecules from an oriented stretched form to a non-oriented balled form takes place and thereby forms a thickening on the bristle ends, upon which the bristles with their thickened ends are inserted into the melted bristle carrier until the melt of the carrier flows behind the thickened end whereby after hardening of the melt an interlocking shape connection is obtained between the bristles and the bristle carrier which joint may also include, in the case of corresponding work material pairs, a material bonding, the interlocking shape connection being independent of the type of materials used for the two parts.

Filed: 1987-05-11
Abstract: To ensure that an ultrasonic tool is driven at an optimum frequency, the 
phases of the voltage applied to the tranducer and the current flowing 
through the tranducer are compared, and an error signal is generated 
dependant upon the divergence of the phase difference from a desired 
difference, which may be zero phase difference. The error signal is 
functional to vary the frequency at which the ultrasonic device is driven, in 
the direction to reduce the error signal, so that the ultrasonic device can be 
driven at zero error signal (i.e. the desired current/voltage phase 
relationship) and thus at maximum efficiency.
