Title: Mains switching adaptor for TV receiver or video recorder - transmits control signal, derived from operating voltage on secondary side to primary side via transformer
Inventor: LEHR STEFFEN DIPL ING
IPC: H02M3/335
Filed: 1991-04-19
Abstract: To the transformer coil is connected a Snubber network (2) for reducing voltage peaks. A control signal (Vsec) is derived on the secondary side from the operating voltage (U1) during the transformer (Tr) rest phase in the form of a retrocharging current (iR). It is transmitted to the primary side and serves for control of the working frequency via a control circuit, and for the ON period of the switching transistor (Ta). In the region of a smaller transmitted power the working frequency is proportionally controlled w.r.t. the transmitted power. In the region of greater transmitted power, the switching-off of the switching transistor takes place in the starting range of the rest phase of the transformer always directly at the end of the control signal, transmitted from the secondary to the primary side. ADVANTAGE - Greater control range and negligible losses.

IPC: G11C29/00
Filed: 1991-09-27
Abstract: A redundancy device increases redundancy efficiency in a semiconductor memory device. Block select signals BLS each determined by a row address are applied to a fuse circuit MFB which also receives column addresses and generates redundancy signals REN. These are passed via selector circuits RS to redundant column decoders RCD, and to a circuit NDC for controlling normal column decoders NCD. Use of both a row address and column address for column redundancy control permits a decrease in the area of redundant cell array as well as an increase in the efficiency of the redundancy operation. <IMAGE>

Patent DE-4225982-A1 (DE)
Inventor: JURMANN ALEXANDER DIPL ING
IPC: C21D9/56
Filed: 1992-08-06
Abstract: The invention relates to a process for the annealing of metallic material in a continuous fashion in a continuous annealing apparatus in which a hydrogen-rich protective gas atmosphere is maintained by a suitable supply of appropriate starting media, wherein the material to be annealed is consecutively heated, annealed and cooled again and wherein the cooling is carried out in a cooling zone of the annealing apparatus supported by coolers. In such annealing processes so-called white dust is formed during the annealing process, by which the aforementioned coolers become increasingly clogged with progressive operating time. In accordance with the invention, for the elimination of this problem it is now proposed that while the annealing operation is in progress the white dust which forms is filtered out of the gas stream or streams flowing through the coolers by means of suitable filters either inside or outside the annealing apparatus.
