Abstract: A roll stamper (3) comprises a roll substrate (11) and a stamper (13) fixed thereto having a convexity and concavity preformat pattern, wherein the stamper has an auxiliary layer comprising a material different from that of the stamper, on the back of the surface on which the convexity and concavity preformat pattern is formed and the roll substrate has a low-melting metal layer (12) on its surface, the auxiliary layer (14) being brought into contact with the low-melting metal layer (12) so that the stamper (13) is fixed to the roll substrate (11). The roll stamper (3) for continuously preparing a substrate used for optical recording mediums, having a convexity and concavity preformat pattern, is prepared by a process comprising the steps of; forming a low-melting metal layer (12) on a roll substrate (11); forming an auxiliary layer (14) comprising a material different from that of the stamper, on the back of a stamper having on its surface a pattern corresponding with convexity and concavity preformat pattern; overlaying said stamper (13) on said roll substrate (11) in such a manner that said low-melting metal layer (12) comes into contact with said auxiliary layer (14); and thereafter melting said low-melting metal layer so that the stamper is fixed to the roll substrate (11). The substrate used for an optical recording medium is prepared by a process comprising continuous steps of melting a resin and extruding the molten resin to form a resin sheet 
and pressing the resin sheet, before it cures, between a roll stamper and a pressure roll disposed opposingly to the roll stamper, to transfer a preformat pattern to the resin sheet.

Abstract: A method and system for processing a multilevel bill of material (44) contained in a relational database (40) that does not require a pre-established limit on the number of levels that can be processed and minimizes user lock out from the same data. A control table (36) keeps track of each component retrieved at a given level of the bill of material, tagging each table entry with a component item identifier, bill of material level, and component sequence number, which identifies the order in which components are processed at each level. A counter is used to keep track of the next level in the bill of material to be processed and a stack data structure is used to indicate the sequence number of the next component to be processed at a given level. The contents of the counter and top of the stack are used to index into the control table to select for processing the entry in the table that has a bill of material level and sequence number matching the contents of the counter and top of stack, respectively.

Abstract: The invention relates to vehicle tyres, in particular pneumatic vehicle tyres, for non-driven axles of utility vehicles. In a manner known per se, these tyres are to have sinusoidally shaped longitudinal grooves such that the amplitude of the sine waves is greater in the groove base than at the periphery. This is achieved by periodically twisting about an axis running in the circumferential direction. The amplitude of the sine waves at the periphery may also be equal to zero. 
<??>In order to reduce the embedding of stones on such tyres, it is proposed according to the invention that the circumferential grooves should have in their axially central areas in each case one offset running steeply with respect to the circumferential direction whilst, in a manner known per se, they only enclose an acute angle with the circumferential direction in the extreme areas.
