Title: Procede et dispositif de pulverisation cathodique magnetiquement renforcee
Inventor: KOUZNETSOV VLADIMIR
IPC: C23C14/35
Filed: 1998-03-11
Abstract: Pour ce procédé de pulvérisation cathodique magnétiquement renforcée, on applique des impulsions de puissance instantanée très élevée, de l'ordre de 0,1 kW à 1 MW. Dans de telles régions de pulvérisation cathodique (23) des électrons, qui sont piégés par le champ magnétique généré par les aimants (17) coopérant avec le champ électrique, se trouvent entre, d'une part l'anode de la cloison (5) de la chambre de pulvérisation cathodique et la cathode de cible (9), à partir de quoi la matière doit être pulvérisée. L'ionisation du gaz de la chambre se produit de préférence à basse puissance dans ces régions (23), ce qui provoque l'érosion non uniforme de la cible (9). Pour chaque crête de puissance ou densité de puissance des impulsions, le gaz des régions considérées et des régions adjacentes passe en état d'ionisation totale, pour une énergie supérieure à ce qui est nécessaire pour la formation d'un arc électrique parasite pour un niveau bas de la puissance fournie. La région (27) dans laquelle cet autre état prévaut est plus homogène et plus étendue que les régions ionisées (23) produites à basse puissance fournie. Il en résulte une plus grande uniformité de l'érosion de la cible (9) et du revêtement du substrat (13). Les impulsions de haute puissance peuvent également s'utiliser dans les pompes d'ions de pulvérisation, leur permettant de commencer à pomper à partir de pressions relativement faibles, par exemple dans une plage allant de 10?-1¿ à 10?-2¿ torr.

Filed: 1998-07-31
Abstract: The present invention relates to pretreating individuals with an effective amount of a flush inhibiting agent for a sufficient period of time prior to the start of single daily dose nicotinic acid therapy to reduce the capacity of nicotinic acid to induce flushing reactions in such individuals during nicotinic acid therapy. In accordance with the present invention, the flush inhibiting agents are administered orally one to four times a day, and preferably one to two times per day, for between about 7 to about 14 days prior to the start of the nicotinic acid therapy. Examples of flush inhibiting agents include nonsteroidal anti-inflammatory agents. Aspirin is a prefered flush inhibiting agent and may be orally administered in daily doses of between about 80 mg to about 1000 mg, and preferably between about 80 mg and about 650 mg, and more preferably between about 80 mg and about 325 mg, during the pretreatment period. Also consistent with the present invention, the pretreatment therapy may be continued during and administered concurrently with the nicotinic acid therapy, in which the nicotinic acid is preferably administered once per day as a single dose during the evening hours or before or at bedtime. The nicotinic acid may be administered alone or in combination with HMG-CoA reductase inhibitors as well as other lipid-altering agents, like cholestyramine and colestipol.

Title: Excavator frame and method of assembly
Inventor: BLETH JAY J
IPC: B62D55/10
Filed: 2000-02-21
Abstract: An excavator undercarriage frame is made to reduce the amount of machining necessary for supporting a swing bearing and ring gear on which an upper swing platform including the cab and operator's platform are mounted. The frame is made in two separate frame sections having top plates and formed peripheral skirts that nest together to form a planar support on which the base ring of a swing bearing and ring gear are mounted.      The frame section plates are thin enough so that they will flex to conform to the base ring of the swing bearing, so it is not necessary to provide a machined surface for the swing bearing. The frame sections are welded together only around the peripheral edges and skirts, so that the distortion in the plates is substantially eliminated. The plates can be then bolted or secured directly to the bearing base ring, preferably using a clamp ring on the bottom of the frame plates and will provide an adequate support with the two plate thicknesses, and will be true and square without machining.
