Abstract: Unité de condensation dont la paroi périphérique délimite une chambre centrale ouverte. La paroi périphérique circonférentielle de la chambre est de forme sinusoïdale pour délimiter une série de chambres de refroidissement espacées circonférentiellement qui s'étendent vers l'extérieur à partir de la chambre centrale pour accroître les échanges de chaleur avec l'atmosphère ambiante. De la vapeur introduite dans la chambre centrale circule librement dans les chambres de refroidissement pour favoriser la condensation de la vapeur en un liquide. Le réservoir de condensation peut être situé à distance d'un réservoir de stockage, au-dessus ou au- dessous du sol, ou bien monté directement sur le réservoir de stockage. Dans les applications où l'unité de condensation est intégrée à un réservoir de stockage, on peut choisir d'injecter la vapeur dans le réservoir de stockage, d'où elle migre dans l'unité de condensation qui sert alors à augmenter la capacité de condensation. Dans une variante, la paroi périphérique de l'unité de condensation peut être entourée d'une chemise de refroidissement contenant un milieu de refroidissement qui accroît l'efficacité de la condensation.

Abstract: Un système de traitement d'eaux usées qui comporte deux réservoirs séparés, mais reliés entre eux, et quatre zones de traitement biologique, notamment une zone aérobie, une microaérophile, une anoxique et une anaérobie, ainsi que deux zones de clarification et une unité de filtration pour séparer les solides du liquide. Le premier réservoir comporte les zones aérobie, microaérophile et anoxique, ainsi qu'une zone de clarification. Le second réservoir comprend la zone anaérobie, une zone de séparation solide-liquide et une unité de filtration. La zone aérobie est un réacteur à agitation par circulation d'air équipé de diffuseurs situés au fond de la zone pour y introduire de l'air. Les bulles d'air mélangent le liquide et son contenu de micro-organismes, fournissant ainsi l'oxygène nécessaire aux processus biologiques aérobies. L'aération entraîne aussi une circulation de liquide entre la zone aérobie et les zones microaérophile et anoxique adjacentes, situées respectivement sur les côtés et au-dessous de la zone aérobie. La zone aérobie contient des micro-organismes de groupes hétérotrophes et autotrophes en suspension qui se développent dans le liquide en circulation appelé liqueur mixte. À l'intérieur de la zone aérobie, une substance porteuse libre ou des objets stationnaires servent de supports à la fixation de la biomasse microbienne et à la formation de biofilm microbien.

Title: Auto-retractable pen with ferromagnetic attachment
Inventor: SUNATORI GO SIMON
IPC: B43K24/02
Filed: 2005-03-18
Granted: 2011-09-20
Abstract: An auto-retractable pen comprises a pen and a cap. The pen comprises a hollow case, an ink cartridge, a mechanical spring and a mobile magnetic element. The cap comprises a cap body and a stationary permanent magnet. The pen or the cap comprises a ferromagnetic element. The pen is capable of attaching to the cap by the magnetic attraction force in a single-hand operation when a user places the mobile magnetic element of the pen in proximity to the stationary permanent magnet of the cap. The writing tip of the pen retracts into the hollow case of the pen when an upward magnetic attraction force becomes greater than a downward mechanical expansion force. The ferromagnetic element provides an increase in strength of the magnetic attachment force by concentrating magnetic flux lines. This invention relates to retractable pens, and the principal use of the invention is for operating a pen with a single hand.

Abstract: A stationary yoke surrounds an outer peripheral surface of a ring-shaped permanent magnet in a certain distance. The ring-shaped permanent magnet is fixed to a rotor and has two poles of N, S poles in a diameter direction.  The stationary yoke includes a first outside yoke and a second outside yoke overlapped in an axial direction and a Hall-element is disposed in a gap of the first outside yoke. An axial height of the first outside yoke changes along the circumferential direction and a height of the second outside yoke has a complementary relation with the height of the first outside yoke, and the first outside yoke and the second outside yoke are overlapped in a certain clearance. A ratio of an amount of the magnetic flux passing through the gap to an amount of the magnetic flux not passing through the gap changes with rotation of the ring-shaped permanent magnet and further, the change of the height causes a change in the magnetic flux amount flowing in the first outside yoke, thereby improving linearity of an output of a Hall-element.
