Title: Method for controlling the application of ink in a printer
Inventor: LUEBBE EVA
IPC: B41F33/00
Filed: 1993-03-19
Abstract: The invention relates to a method for controlling the application of ink in a printer on the basis of colorimetric detection of the print quality of the printed products. The object of the invention is to provide a method which, while using a colorimetric detection of the print quality, allows more satisfactorily for the peculiar features of the human eye. This object is achieved in that   a.) the measurement signals acquired by the measuring points of the print image area by means of colour sensors are fed to a computer system for the purpose of computational detection of the colour tone, the brightness and the saturation, which computer system determines these values using colour space models which are known per se, b.) the computer system determines the change in the print colours from the changes in the values of the colour tone, the brightness and the saturation by a comparison with set values, with identical modes of measurement, of "sample sheets", the value for the saturation being used, together with the value for brightness, in order to differentiate the dark print colours from the bright ones, and c.) to the values of the colour tone of the measurement points ... colour spacing tolerance values for each colour tone area which correspond to the human sensitivity of the eye are fed to the computer system and evaluated together with the said colour spacing tolerance values.

Patent DE-4312962-A1 (DE)
Title: Infrared light source for any wavelength range in infrared
Inventor: MENSCH MARTIN DIPL ING
IPC: H01K1/28
Filed: 1993-04-21
Abstract: The invention relates to a light source which emits in any desired wavelength range in the infrared spectrum. An incandescent body (glowing body) is made to glow by electrical means in a closed space which is gastight and filled with a non-oxidising gas or gas mixture. The infrared light passes outside through a material which bounds the space at one or more points and which allows the infrared light of the desired wavelength to be transmitted. As a result, a high incandescent temperature can be achieved on the one hand, and on the other hand a high yield of the infrared light emitted by the incandescent body. The invention can be designed as a small IR light source with a high intensity, and can thus be used for transilluminating cuvettes and for illuminating IR sensors.
Patent DE-4313179-A1 (DE)
Title: Surface preparation for circular workpieces - using grinding bands reciprocally moved between two sets of reels and with band tension control
Inventor: GRILLI LUCIO
IPC: B24B19/00
Filed: 1993-04-19
Abstract: The surface treatment uses a moving grinding band (5, 6) moved between two reels and with a band tensioner (39) to control the working effect. The rotating workpiece (30) is positioned onto the moving band by a position control. A microprocessor (50) controls the workpiece positioning as well as the band speed- and tension. Sensors monitor the band speed and the tension. With two sets of reels and two bands a continuous operation is possible even when changing one band. The relative reel diameters are monitored to regulate the reel drive speeds. ADVANTAGE - Improved throughput, minimum of dead time.

Title: Device for picking up structure-borne sound from workpieces, tools or their clamping device for tool monitoring
Inventor: NORDMANN KLAUS DR ING
IPC: B23Q17/09
Filed: 1993-05-17
Abstract: The invention relates to a device for picking up structure-borne sound from workpieces, tools or their clamping device for tool monitoring via a flexible spring-steel element as waveguide. The advantage of the invention lies in the direct pick up of sound from workpieces or tools via a spring-steel element without the sensor itself having to come into contact with the workpiece, tool or other machine parts. The sensor is screwed to a sound-absorbing mounting so that disturbing structure-borne sound is kept away from it. The spring-steel element represents a waveguide with a defined sound-transmission behaviour with which reproducible measured values are obtained.

Title: Synapse MOS transistor esp. for neural network - has gate electrodes formed on common oxide layer having weighted lengths relative to source and drain electrodes
Inventor: CHUNG HO-SUN
IPC: G06N3/063
Filed: 1993-05-28
Abstract: The synopsis MOS transistor has an n+ tunnel formed in a p substrate (200) in order to form a source electrode (201) and a drain electrode (202). An oxide (Si O2) layer (204) is formed on the p substrate. Six gate electrodes are formed on the oxide layer (204) which are of the same width but with the lengths different. The lengths (L) from source and drain electrodes are binary weighted (1,2,4,8,16,32) and create a staircase profile. The form creates an NMOS structure and the current of the gates increase with increased gate size. ADVANTAGE - Reduced chip area.
Patent DE-4322577-A1 (DE)
Title: Stitch-forming machine with at least one boring device
Inventor: SCHILLING LOTHAR
IPC: D05C7/04
Filed: 1993-07-07
Abstract: A stitch-forming machine with at least one boring device having a drive for the borer, of which the depth of penetration into the workpiece is adjustable, is to be designed in such a way that, at the least possible outlay in terms of the drive, the depth of penetration of the borer can be adjusted without the need for a time-consuming setting operation and, irrespective of this adjustment, the borer, when in the upper reversal position of its boring stroke, is always held above the topside of the workpiece. For this purpose, the borer can be moved as a result of a first movement of the drive out of a position of rest, located at a distance from the upper reversal position of its boring stroke, into a position of readiness which is located below this and corresponds to the upper reversal position and from which it executes its boring stroke as a result of a second movement of the drive, the amount of which depends on the adjustment of the depth of penetration. <IMAGE>

Patent DE-4437417-A1 (DE)
Title: Method for monitoring digital signal connections
Inventor: WOLF HELMUT
IPC: H04L12/26
Filed: 1994-10-19
Abstract: In a method for monitoring bidirectional digital signal connections between a starting point and an end point in each direction of transmission, the transmission quality is determined with the aid of additional information also transmitted in in each case one direction of transmission and the result is transmitted as message in the other direction of transmission. To monitor the state of quality, errors are detected in each case at the endpoint by comparing additional information items relating to the quality at the starting point with quality information items obtained at the endpoint, which errors are accumulated over a predetermined time interval to form an error sum which is assessed. The result of this assessment is transmitted to the starting point as message. To monitor for correct switching-through, a starting point identification is added to the message which is compared at the endpoint with a starting point identification to be expected which has previously been reported to the endpoint. A mismatch is signalled back and the outgoing signal is replaced by an alarm indication signal (AIS). <IMAGE>
