Inventor: DRISCOLL EDWARD K
IPC: G11B33/14
Filed: 1993-07-20
Granted: 1998-08-25
Abstract: A disk array subsystem for use in a data processing system.  In one embodiment, the disk array subsystem comprises a generally rectangular chassis having a top wall, a bottom wall, a pair of side walls, an open front end and an open rear end.  A fan pack is removably mounted over the open rear of the chassis to cool the contents thereof by drawing air into the chassis through the open front end and out of the chassis through the open rear end.  Disposed within the chassis are three power supplies, a pair of controller boards, a backplane, and a set of twenty disk drive modules.  A mounting structure comprising four first disk drive module guide plates and a pair of second disk drive module guides is fixedly mounted within the chassis for removably mounting the disk drive modules in the chassis through the open front end and for placing the disk drive modules in approximate alignment with the backplane for electrical connection therewith.  Each first guide plate is shaped to include five parallel slotted channels, and each second disk drive module guide plate is shaped to include ten parallel grooves.  Each of the twenty disk drive modules includes an elongated frame having a longitudinally extending T-bar adapted for slidable insertion into one of the slotted channels and a longitudinally extending fin adapted for slidable insertion into one of the grooves.  The T-bar is shaped to include a detente, and the slotted channel is shaped to include a pawl, the detente and the pawl being interengageable so as to permit the disk drive module to be secured in place on its assocated slotted channel.

Inventor: KEPPLINGER WERNER
IPC: C21B13/00
Filed: 1993-10-20
Granted: 2005-12-13
Abstract: A process for producing molten pig iron or molten steel pre-products from charging substances formed of iron ores and fluxes and at least partially comprising fines, wherein the charging substances are directly reduced to sponge iron in at least one reduction zone by the whirl layer process, the sponge iron is melted in a melting-gasifying zone under supply of carbon carriers and oxygen-containing gas, and a CO and H2-containing reducing gas is produced, which is injected into the reduction zone, is reacted there, is withdrawn as an export gas and is supplied to a consumer, is to be improved with a view to rendering feasible the use of fine ore in an economic manner.      This is effected in that - primarily hematite and/or magnetite fine ores and/or ore dusts are subjected to preheating by the whirl layer process in a preheating zone, - the thus preheated charging substances are completely reduced to a major extent in at least one consecutively arranged reduction zone, - whereupon at least the more finely particulate charging substances are charged into the fluidized bed and/or, if desired, also into the fixed bed, of the melting-gasifying zone by forced conveyance, preferably by pneumatic conveyance, and are melted there.

Patent CA-2118555-C (CA)
Inventor: KOBAYASHI MASAKI
IPC: B60R1/08
Filed: 1994-03-08
Granted: 1999-04-06
Abstract: The mirror system has devices for adjusting the reflectivities of the interior and exterior rearview mirrors to different values to correct the driver's unbalanced rearview visibility. These devices include, for instance, a liquid-phase ECD (Electrochromic Device) used in the interior rearview mirror and a solid-state ECD used in the exterior rearview mirror so that appropriate reflectivities of the two mirrors can be obtained, even if they experience the same operation conditions. When the same-type ECD is used for both interior and exterior rearview mirrors, the drive voltage for the exterior rearview mirror is made lower than that for interior rearview mirror to make the latter's reflectivity smaller than the former's. For this purpose, transforming circuits are provided as well as terminal voltage sensing and controlling circuits.

Title: Wafer release method and apparatus
Inventor: BLAKE JULIAN GASKILL
IPC: H01L21/265
Filed: 1994-03-09
Granted: 2000-04-04
Abstract: A wafer position and clamp sensor. A circuit (114) monitors capacitance between two electrodes (22,24) within a wafer support. With no wafer on the support, the capacitance falls in one range, with the waferin place but not clamped, the capacitance falls in a second range and with the wafer held in place by an electrostatic attraction the capacitance falls in a third range. The sensed capacitance is converted to a frequency and then a D.C. voltage level that can easily be sensed and used to confirm wafer placement and then wafer clamping. After the wafer has been treated, the wafer is removed and the next subsequent wafer treated, A clamping voltage applied to clamp the wafer to its support is reversed at a controlled frequency to release the wafer. The voltage reversal disrupts the electrostatic attraction between the wafer and its support.

Ladite boîte est renversée juste avant son remplissage de manière à évacuer l'eau, et elle est lavée selon une technique classique puis à nouveau renversée pour le remplissage. Ledit procédé peut être automatisé, auquel cas les boîtes sont acheminées sur un convoyeur vers le poste d'évacuation d'air, vers le poste de purge et vers le poste de remplissage d'eau de manière à être purgées simultanément en lots. Deux unités de purge par lots (94, 96) peuvent être prévues et exploitées de manière asynchrone afin d'assurer un flux continu de boîtes purgées partiellement remplies d'eau prêtes à être envoyées au poste de lavage (56) et de remplissage (64). Dans un autre mode de réalisation, de l'azote liquide ou gazeux est envoyé dans le dispositif de production de mousse avant ou après que celui-ci soit inséré dans la boîte, et l'orifice fait par le dispositif de remplissage (24) est bouché de sorte que la charge de gaz reste dans le dispositif de production de mousse.

Title: Non-oxidizing polymeric medical implant
Inventor: SUN DEH-CHUAN
IPC: C08F2/46
Filed: 1994-04-26
Granted: 2000-07-04
Abstract: A medical implant made of polymeric material having an increased oxidation resistance is formed by a method including the steps of placing a resin powder in a sealed container. A substantial portion of the oxygen is removed from the sealed container by either a vacuum, an oxygen absorbent or by flushing with inert gas. The container is then repressurized with a gas such as nitrogen, argon, helium or neon so that long term storage may be possible. On use, the resin is transferred to a forming device which both melts and forms the resin in an oxygen reduced atmosphere to produce a polymeric raw material such as a rod or bar stock. The medical implant is then formed from this raw material annealed and sealed in an airtight package in an oxygen reduced atmosphere. The implant is then radiation sterilized and thereafter annealed in the package for a predetermined time and temperature sufficient to form cross-links between any free radicals in neighboring polymeric chains.
