Title: Electrostatic photocopier with endless band image transfer mechanism - has image forming developing transfer and fixing units built as combined space-saving assembly
Inventor: MATSUNO JUNICHI
IPC: G03G15/16
Filed: 1992-04-22
Abstract: An electrostatic photocopier has a photosensitive drum (9) and a developer unit (10) which forms a toner image of the original on the drum. A transfer roller (13) transfers the toner image to an endless band (5) which rotates to bring the image to a fixing station, which also receives a copy sheet (1) via the transport mechanism (2).

Patent DE-4312127-A1 (DE)
Title: Simplified junction connection for three-dimensional frameworks formed from tubes
Inventor: MYLAEUS ARMIN
IPC: F16B7/18
Filed: 1993-04-14
Abstract: The invention relates to a simplified junction connection for three-dimensional frameworks. It is less expensive and more reliable in assembly, maintaining the prescribed screw-in depth into the junction. It dispenses with bores for checking the screw-in depth and with plug-through holes in the tubes for the connecting screws. The material is thus not weakened and can be utilised to the full extent. Moreover, due to the avoidance of any openings, moisture cannot penetrate. For the first time, use can be made, as connector bolt, of a standard threaded bolt and, as driving sleeve, of a thick-walled tube section. The connection of two parts is achieved by simple pressing. At the end of the assembly operation, the fitter, according to the invention, feels a strong resistance to further turning of the screw. He thus no longer has to carry out tedious checks of the screw-in depth in a check bore, and assembly is accelerated. Upon the last possible turn of the screw, there is a desired pinching of the material between driving sleeve and threaded bolt, said pinching preventing undesired loosening. The threads in the tube end and driving sleeve are protected during transportation.
