Patent DE-3105514-A1 (DE)
Title: Drive connection for a printer, in particular for the recording medium drive of the printer
Inventor: LOHRMANN GERHARD
IPC: B41J19/20
Filed: 1981-02-12
Abstract: This drive connection consists of a shaft (1) and a driving wheel (2 or 4) which are firmly connected to one another axially and radially. A radial play existing between the drive shaft (1) and the driving wheel (2 or 4) has a negative effect on the printing operations during the conveyance of recording media which are perforated in the edge regions. Producing the hub bore of the driving wheel without radial play would require a very tight, expensive tolerance. Drive connections for drive shafts which are polygonal in their cross-sectional profile are even more difficult in terms of being true to shape and in terms of the tolerance of the hub bore. Consequently, a drive connection without radial play, without particularly expensive tolerances and, at the same time, with axial fixing is to be provided, in which case the latter should not require great outlay. For this purpose, the driving wheel (2 or 4) is connected to the shaft (1) by means of a hub ring (2a) with interconnection of a clamping piece (3), provided with the cross-sectional profile (18) of the shaft (1) and formed with resilient tongues (16a to 16f) distributed over the circumference (15) and extending axially, whilst maintaining an axial force by means of the hub ring (2a). With this design, two driving wheels (2 and 4) can be connected to the shaft (1) at the same time. <IMAGE>

Title: Method of structuring (patterning) plates with insulating annular zones in the vicinity of the openings of holes by electroplating and etching
Inventor: TRAUSCH GUENTER DIPL ING
IPC: H05K3/38
Filed: 1981-05-08
Abstract: The entire plate surface is coated with a thin metal layer (2) and then that side of the plate which is adjacent to the desired annular zones is clad with a negative-working dry resist (3) in such a way that said resist also penetrates the holes. The resist is then irradiated with UV light (5) through the holes from the opposite side (1b) and dry resist is also applied to the hitherto unclad side of the plate. After both sides of the plate have been irradiated with UV light through masks aligned with respect to the hole array, the non-irradiated resist parts are stripped in a developer solution. After that, metal is electrodeposited (7) on all the exposed metal surfaces, the resist is removed and the metallisation underneath it is removed by etching selectively with respect to the electrodes. Application, for example, in flat plasma display screens. <IMAGE>
Patent DE-3119032-A1 (DE)
Title: Solid-state image scanning device
Inventor: HORII KENJU
IPC: H04N5/3722
Filed: 1981-05-13
Abstract: A solid-state image scanning device is created in which the phenomenon of flare can be prevented without deterioration in other characteristics such as sensitivity. According to Figure 2, flare is prevented by the fact that the flare charge which flows over into the charge transfer element columns (2) due to an intensive light irradiation of photoelectric transducer element columns (1) is discharged to the outside during a light signal storage period through charge transfer element columns (2), selection gate areas (24) and excess charge absorption areas (23). In the solid-state image scanning device according to the invention, the signal charge existing in the photoelectric transducer element columns (1) after removal of the flare charge is read out of a charge output area (4) via charge transfer element columns (2), selection gate areas (24) and storage areas (22) so that it is possible to obtain an image signal which is free of the flare charge exhibiting extremely disadvantageous effects for image reproduction. In the solid-state image scanning device according to the invention, the charge transfer element columns (2) are used both as a signal read-out path required for forming the image signal and as an extraction path for the flare charge so that there is no necessity for fitting a particular anti-flare mechanism in the environment of the photoelectric transducer section. The disadvantage existing in the prior art that the photoelectric conversion efficiency is reduced by the otherwise unavoidable loss of area of the photoelectric transducer section can be completely overcome. Due to the solid-state image scanning device according to the invention, the flare phenomenon can thus be avoided without any loss in the remaining characteristic data and the possibilities of using the solid-state image scanning device under highly intensive light irradiation can be extended to a high degree. <IMAGE>

Title: Life clocks for earth dwellers and flying vehicles
Inventor: POISEL OTTO KARL DIPL ING
IPC: G04G99/00
Filed: 1981-10-21
Abstract: The invention relates to life clocks which indicate to earth dwellers all the time data as well as their actual years of life even after flights in space, and in the case of flying vehicles used in cosmic space flight, apart from the earth time data further also determine and display as on-board instruments the flight times and even the flight speeds taking time dilatation into account. Each flying vehicle life clock is assembled from a clock (1), at least two chips (2, 3), two processors (4, 5), a digital display (6), a switch (7), four energy sources (8, 9, 10, 11) and a computer (12). The function of both types of life clock takes account of the earth time data and the effect of time dilatation, which depends on the speed of motion of each celestial body. The flight speed of the flying vehicle is determined with the aid of the relativity coefficient. These facts render life clocks for earth dwellers and flying vehicles indispensable in cosmic space flight. Moreover, in cosmic space flights they serve as flight recorders and help us to identify the cause of an accident in the event of breakdown. <IMAGE>
