Title: Ultrasonic scanner for monitoring blood flow
Inventor: SHIRAI TAKESHI
IPC: G01N29/40
Filed: 1995-08-28
Abstract: The ultrasonic scanner (1) consists of an ultra-sonic receiver (3) for ultra-sonic beams reflected from scanning lines extending within a subject and provide signals (11) corresponding to those scanning lines. A subtraction signal generator (12) generates a predetermined subtraction signal and a difference signal generator (12) calculates an analogue signal from the difference between received and subtraction signals. An A/D converter (12) provides a digital difference signal from which information is calculated (5, 6, 7) which represents movement within the subject. A monitor (8) then displays this information.

Title: Heat exchanger for gas water heater
Inventor: SCHMIDT ERNST DIPL ING
IPC: F28F1/32

Title: Damage reversal method for CCD detectors affected by UV radiation
Inventor: SOKOLOWSKKI-TINTEN KLAUS DR
IPC: G01J1/42
Filed: 1996-06-03
Abstract: The method is for reversing the damage caused by UV radiation within the range 20 to 120 nm in terms of reduced sensitivity and increased dark signal error in CCD electromagnetic radiation detectors. The method employs a mercury vapour discharge source with a spectral output between 200 and 300 nm for irradiation of the defective CCD during a period of typically 4 minutes. The duration of remedial treatment is dependent on the wavelength, intensity and dosage of the damaging source and a reference confirming the recovery achieved is obtained by monitoring dark signal levels at a controlled room temperature of 20 deg C.

Patent DE-19642116-A1 (DE)
Inventor: PANZER SIEGFRIED DR
IPC: H01J37/30
Filed: 1996-10-12
Abstract: Multiple methods are known to process materials or alter their properties using an electron beam. Until now, it was not possible to impinge upon minuscule surface sections (pixel) with a given arrangement on the surface in order to achieve certain effects. According to the invention, the object to be impinged upon is moved contact-free under a mask. A bidimensional deflectable electron beam oscillating at a high frequency perpendicular to the direction of movement of the object is moved on the mask, the speed being essentially faster than that of the movement of the object. Said method can be used for processing any material, preferably plane or band-shaped objects, in order to achieve processing effects by means of physical or chemical reaction.
