Patent FR-2536923-A1 (FR)
Title: Comparator which memorises offset voltage and application to an analogue-digital converter with parallel structure.
Inventor: GUILLAUME PASCAL
IPC: H03M1/00
Filed: 1982-11-26
Abstract: The invention relates to an analogue comparator with elimination of the offset voltage. This comparator conventionally includes an operational amplifier 12 capable of being short-circuited by a switch Ic during a first phase a of comparison while a reference voltage Vr from a precision divider bridge is applied to an input capacitor C. In a second phase c the voltage Vin to be compared is applied to the capacitor C. According to the invention, to avoid the circulation of transient currents due to a redistribution of charges between the capacitor C and the stray input capacitance of the operational amplifier 12, this circulation corrupting the value of the reference voltage Vr, an additional switching phase d is provided during which a compensation voltage Vc close to the reference voltage Vr is applied to the capacitor C by a voltage source with low output impedance. Application to the comparators of fast analogue-digital converters with parallel structure.

Patent FR-2518911-A1 (FR)
Inventor: BERGER DIETRICH
IPC: B26D7/26
Filed: 1982-12-23
Abstract: The invention relates to the structural design of forming tools, in particular the arrangement of the active cutting and/or bending inserts. The aim of the invention is to design the arrangement of the active forming inserts in such a way that it is possible to dispense with the very involved fitting work for the inserts due to the elimination of the control of the dimension chain tolerances and it is possible to perform a rapid change of an insert in the case of wear, damage or slight changes. The technical object is to substantially minimise the production and repair expenditure for forming tools by the special arrangement of the active forming inserts. According to the invention, this is achieved by virtue of the fact that the cutting and/or bending inserts are arranged in such a way that a small gap arises between the contact faces of the individual inserts due to the negative tolerance introduced. The invention can be employed in forming tools with active elements which consist of a plurality of inserts and in which parts are produced which do not make any special requirements as regards the cut edges.
