摘要:
A method of forming a button-type battery including:
a) positioning first and second terminal housing members 12 and 20 in facing juxtaposition to one another, and providing an anode 26, a cathode 28 and an electrolyte 30 intermediate the first and second terminal housing member central portions; b) providing a peripheral insulative sealing gasket 34 intermediate the first 12 and second 20 terminal housing members, the insulative sealing gasket 34 being in the shape of an annulus and having a radial extent which extends radially outward beyond the surrounding peripheral portions of the first and second terminal housing members; c) moving at least one of the juxtaposed first 12 and second 20 terminal housing members in the direction of the other to push the first terminal housing member container wall 14 against the first gasket face 38 and to simultaneously force the second terminal housing member peripheral portion 22 against the second gasket face 40, and continuing such moving to bend the insulative gasket 34 about the container wall 14 and force it to be received within the first terminal housing member 12; and d) after the moving step, crimping the container wall 14 and sealing gasket 34 against the peripheral portion 22 of the second terminal housing member to form an enclosed housing.
摘要:
A pseudo random number generator comprises a linear feedback shift register switchably operable in a first mode, and in a second mode. In the second mode the shift register consumes more power than in the first mode. The method of generating a pseudo random number comprises: providing a linear feedback shift register; providing an oscillator which generates clock signals used by the linear feedback shift register for shifting; and providing a first power level to the oscillator when a pseudo random number is required, and providing a second power level, lower than the first power level, to the oscillator at other times.

摘要:
A polishing pad for semiconductor wafers (P), having a face (25) shaped by a series of voids (27, 37, 33). The voids are substantially the same size, but the frequency of the voids increases with increasing radial distance to provide a constant, or nearly constant, surface contact rate to a workpiece (P) such as a semiconductor wafer, in order to effect improved planarity of the workpiece.

A radio frequency identification (RFID) interrogator sends parameters and return link configuration information to an RFID tag. The tag uses the parameters to determine whether or not to respond with a reply signal. The tag uses the return link configuration information to select a modulation type from amongst a plurality of modulation types to modulate the reply signal.
