Abstract: A semiconductor memory device includes a memory cell array (10) having a plurality of memory cells (MC) and formed by a mask ROM, the memory cell array having a data area (10a) in which data (SO1 - SO16) of n bits (n is an arbitrary number) is stored and a parity area (10b) in which a one-bit parity code (Pb) relating to the data is stored. A control circuit (13, 14) supplies the memory cell array with an address and reads out the data and the one-bit parity code designated by the address. A parity check circuit (16) determines whether or not the data read out from the memory cell array has a bit error and generates correction data (CB) indicating a determination result. A memory (17) stores defective output indicating data (S1 - S16) indicating one of the n bits of the data having the bit error. A data correction circuit (15) corrects one of the n bits of the data indicated by the defective output indicating data by the correction bit.

Abstract: In the method for partially restoring a sewer (12) buried in the ground, a fibre mat (19) which covers the damaged zone of the sewer (12) on the inside and is impregnated with curable resin is placed around a hose-shaped support (6) of a packer, which support can be deformed by means of pressure. The external diameter of the support (6) is considerably smaller than the diameter of the sewer to be restored. The length of the support is larger than the wound fibre mat. The resin-impregnated fibre mat layer which is located facing the hose-shaped support (6) is fixed on the hose-shaped support by increased frictional engagement. During the increase in the diameter of the fibre mat winding, which is carried out by inflating the hose-shaped support, the hose-shaped support is rotated with the fibre mat winding, and the fibre mat layers are pressed against one another during the enlargement of the diameter of the winding. The resin which is displaced in consequence is then pressed into cracks (10) and into other damaged points in the tubular section of the sewer which is to be restored. A fibre-free resin ring is formed on the ends of the cladding. <IMAGE>

Abstract: A method and an apparatus for treating workpieces with a fluid, in particular for cleaning metallic workpieces prior to a subsequent heat treatment are disclosed. The workpieces are positioned in an air-tight washing vessel. The vessel is filled with an immersion bath substantially covering the workpieces and having a temperature of between 50 DEG  C. and 90 DEG  C. After closing the washing vessel it is evacuated down to a vacuum having a pressure being below the saturation vapor pressure of the fluid at the prevailing temperature. Thus, the fluid starts to boil although its temperature is substantially below the boiling temperature of the fluid at atmospheric pressure. After a certain period of time of maintaining the vacuum and the boiling, the vacuum is relieved and the bath is discharged.
