Patent CA-2412370-A1 (CA)
Title: Use of a u-groove as an alternative to using a v-groove for protecting silicon against dicing induced damage
Inventor: TANDON JAGDISH C
IPC: H01L21/301
Filed: 2002-11-22
Abstract: The present disclosure relates that by modifying chip die dicing methodology to a U-groove profile from a V-groove profile by modifying the second etch step to be a dry etch instead of a wet etch results in a direct cost savings by eliminating a more expensive process step, as well as the need for stripping the developed photoresist layer. Furthermore, going to a U-groove profile accomplishes additional indirect and greater cost savings resulting from increased process throughput, improved yield, and reduced metal layer defects.

Title: Method for the improvement of current efficiency in electrolysis
Inventor: VIRTANEN HENRI
IPC: C25C7/06
Filed: 2002-06-14
Abstract: The invention relates to a method for the improvement of current efficiency in electrolysis. According to the method, a theoretical cell voltage is first calculated, which is compared with the measured voltage. The cumulative difference between the theoretical and measured cell voltage is monitored constantly and when this difference is proportioned to the current efficiency, information on the status of the process can be obtained continually. A  decrease in current efficiency is a clear indicator of short circuits between the electrodes, and by means of the method according to the invention, it is possible to concentrate the short circuit removal work onto the correct cell groups, from the point of view of the current efficiency of the electrolysis.

Title: Process for identifying eukariotic tumor cells or bacteria arboring a genomic alteration in at least one part of a gene encoding for a transcription factor
Inventor: BROCHIER CELINE
IPC: A61K48/00
Filed: 2004-02-26
Abstract: Background: Phylogenetic analysis of the Archaea has been mainly established by IOS rRNA sequence comparison.  With the accumulation of completely sequenced genomes, it is now possible to test alternative approaches by using large sequence datasets.  We analyzed archaent phylogeny using two concatenated datasets consisting of 14 proteins involved in transcription and 53 ribosomal proteins (3.275 and 6.377) positions respectively).   Results:  Important relationships were confirmed, notably the dichotomy of the archaeal domain as represented by the Crenarchaeotic and Fluryarchaeoa, the sister grouping of Sulfolobales and Aeropyrum pernix, and the monophyly of a large group comprising Thermophanatales, Archaeoglus fulgidus.  Methanosacrinable Halobacteriales, with the latter two orders forming a robust cluster.  The main difference concerned the position of Methanopyrus kanderli, which grouped with Methanoceles and Methanobacteriales in the translation tree, whereas it emerged at the base of the euryetharates in the transcription tree.  The incongruent placement of M. kandleri is likely to be the results of a reconstruction artifact due to the high evolutionary rates displayed by the components of its transcription apparatus.   Conclusions: We show that two informational systems transcription and translation, provide a largely congruent signal for archaenl phylogeny, in particular, our analyses support the appearance of methanogenesis after the divergence of the Thermocolales and a late emergence of aerobic respiration from within methanogenic ancestors.  We discuss the possible link between the evolutionary acceleration of the transcription machiery in M. kandleri and several unique features of this archaeon, in particular the absence of the elongation transcription factor TPS.~

Title: Park brake for a disc brake system and disc brake system incorporating same
Inventor: NOWAK STAN
IPC: F16D65/14
Filed: 2002-08-30
Abstract: A park brake (14) is incorporated into a housing (10) of a disc brake system (12). The housing (10) is in the form of an annular ring having a plurality of cavities (16) for housing service brake pistons which act on brake pads (18) to selectively force the brake pads (18) onto a brake disc to produce a surface brake effect. The park brake (14) includes an actuator (23) supported by the housing (10) which is switchable between an applied state where it forces the brake pad (18) into contact with the brake disc of the system (10) independent of the action of the service brake pistons to produce a park brake effect, and a released state where the actuator (23) allows the brake pad (18) to become disengaged from the brake disc. The actuator (23) includes a hydraulically operated park brake piston (27) having a rod (24) extending therefrom. The rod (24) is slidably retained within a hole (26) formed in the housing (10) and is arranged to abut or otherwise apply force to the brake pad (18). When fluid pressure is applied to the pad brake piston (27) it retracts the rod (27) into the housing (10) releasing the park brake (14). In the absences of the application of fluid pressure, a spring (34) of the actuator (23) operates to switch the actuator (23) to an applied state where the rod (24) pushes on the pad (18) forcing it into contact with the brake disc thereby providing the park brake effect.
