Patent DE-4318721-A1 (DE)
Title: Thermic fixture device - involves pair of rotating rollers in press contact with each other, heat section connected to at least one roller and picture retainer
Inventor: MITANI MASAO
IPC: G03G15/20
Filed: 1993-06-04
Abstract: The picture retainer (1) has a picture with unfixed toner (12) which is pushed through an intermediate space between the rollers (9,10) so that it is thermically fixed by melting. The heat section (1) has a heating an cooling deviec (13,14) of unit structure, which incorporates a cooler and a heater acting as retainer. The fixture device comprises a thin, endless metal strip (8) which rotates whilst it contacts the unit structure. A non-adhesive film is on the outer upper surface of the strip, and a drive roller (9) causes the endless metal strip to rotate by applying a pressure to it. The surface temp. in a section in which the endless metal strip is in press contact with the picture retainer (11) is initially raised to a temp. near to the melting point of the toner and then cooled. The non-adhesive film on the endless metal strip is either of silicon rubber or silicon resin. USE/ADVANTAGE - To solve problems with a SURF-type fixture in electrophotography.

Title: Method for receiver-side detection of an AC signal voltage transmitted via a communication line
Inventor: FINK GUENTER
IPC: H04M19/04
Filed: 1993-08-27
Abstract: AC signal voltages, in particular AC call (ringing) voltages which are used for activating the call signal at a telephone set of a small communications system, are intended to be detected on the receiver side. The most widely varied of coupled voltages are superposed on them. The method for recognising the AC signal voltage contains two steps. A particular number of time periods, which in each case exceed a predetermined time, are first summed. If the total result lies within a particular limit-value range, then the transmitted AC signal voltage is thereby recognised as the voltage to be detected. If this is not the case, then a sliding average with regard to the measured valid time periods takes place as a further step. This continues until the respectively obtained partial result of the measurement is recognised as a valid value for the AC signal voltage to be detected or until a predetermined detection time has elapsed. <IMAGE>
