Patent FR-2676578-A1 (FR)
Title: Semiconductor memory device capable of executing non-periodic regeneration operations
Inventor: JUN-YOUNG JEON
IPC: G11C11/406
Filed: 1991-07-26
Abstract: A semiconductor memory device containing memory cells which store in a continuous manner an information item given by means of an overwrite, that is to say a regeneration operation capable of executing non-periodic regeneration operations. The semiconductor memory element comprises, internally, a regeneration request signal generator (100A) containing a reference memory cell (51) connected to a word line in the memory device (100). The regeneration request signal generator (100A) produces regeneration request signals only upon the erasure of the information item stored in the memory cell. The regeneration request signals output act such that regeneration signals are transferred to the memory cell. Thus, non-periodic regeneration operations can be executed, thereby lowering the current consumption and increasing the number of information input/output operations.

Title: Adjustable locking system for plate deep-freeze and tool for adjusting the system
Inventor: GUY QUILLIOU
IPC: F25D31/00
Filed: 1991-09-04
Abstract: Locking system for plate deep-freeze, consisting of rules, arranged between the plates and on which ramps are formed interacting with ramps provided on the plates, so that longitudinal movement of the rules with respect to the plates causes a vertical movement of the rules, altering the separation of the plates. In order to avoid the rules being blocked by ice and to allow easy and accurate adjustment of the spacing between the plates, the locking system which is the subject of the invention is characterised in that the rules (12) are suspended from the plates (10) by support blocks (16), and their upper edge is fitted with teeth (20) of sawtooth shape, and in that the plates bear on the rules via heels (22) in which a notch is cut out, the inclined base of which constitutes a ramp having the same slope as the teeth of the rules, each heel receiving, in a respective notch, one tooth of one rule.

Title: Detecting target nucleic acid by restriction enzyme amplification
Inventor: ROB GRUTERS
IPC: C12Q1/68
Filed: 1992-11-10
Abstract: System for detecting a target nucleic acid sequence by restriction enzymatic amplification comprises 2 probes, partly double stranded and fixed to a solid support. These probes have a first strand contg. an endonuclease recognition site and extending up to the enzyme cleavage site, and a second strand with a region complementary to the first strand, extending from at least the recognition site to the cleavage site. This second strand extends (as a single strand) beyond the cleavage site to produce a region which, for one probe, is complementary to the target, and, for the other probe, substantially (pref. perfectly) complementary to the product of single-strand cleavage of the first probe. One of the single-stranded regions has a 5'-end, the other a 3'-end. The endonuclease is of type II; it has a double stranded fixing site; cuts to produce an overhanging end and has a cleavage site outside its recognition site.
