Patent number: 6030514Abstract: A target for sputtering is subjected to a surface treatment process and special packaging after target manufacture for improved sputtering performance and process and yield by reducing particulates. The sputtering target is first surface treated to remove oxides, impurities and contaminants. The surface treated target is then covered with a metallic enclosure and, optionally, a passivating barrier layer. The metallic enclosure protects the target surface from direct contact with subsequently employed packaging material such as plastic bags, thereby eliminating sources of organic materials during sputtering operations. The surface treatment of the target removes deformed material, smearing, twins, or burrs and the like from the target surface, reducing "burn-in" or sputter conditioning time prior to production sputtering of thin films.Type: GrantFiled: May 2, 1997Date of Patent: February 29, 2000Assignees: Sony Corporation, Materials Research CorporationInventors: John A.

Patent number: 5457939Abstract: A process for packaging foodstuffs in substantially rigid containers. A desired quantity of foodstuff to be packaged is placed in the container, a quantity of aqueous liquid in an amount sufficient to generate, when boiled, a volume of vapor sufficiently in excess of the volume of the container to substantially completely displace all other gases from the container, is added. The container is closed but not sealed, so as to permit communication between the interior of the container and the ambient atmosphere. The container and its contents are warmed to a temperature sufficient to generate the volume of vapor when the container is subjected to a pressure lower than atmospheric pressure. The temperature is kept as low as possible so that no cooking of the foodstuffs occurs. After warming, the containers are exposed to a low pressure so that the liquid in the container boils. The boiling liquid generates vapor in the container sufficient to drive out and displace other gases from the container.Type: GrantFiled: September 1, 1993Date of Patent: October 17, 1995Assignee: Optimal Food Processing Research, Inc.Inventors: Jean-Francois M.

Patent number: 4389239Abstract: The activation of a mass of metal granules capable of storing hydrogen with the formation of hydride in a pressure vessel, instead of having to be activated before use by repeated heating in a hydrogen atmosphere followed by cooling and evacuation before the next heating, is activated in the pressure vessel used for storage by first heating a small portion of the granulate to the necessary activation temperature and then allowing the heat developed by the activation of that portion to produce the activation of the remainder of the granulate. It is found that it thus possible to provide complete activation with only one heating step. The small portion that is first activated may be a part of the granulate that is of a different composition that is easier to activate, for example, LaNi.sub.5, which can be activated at room temperature, or iron-titanium alloys that are capable of activation under 100.degree.

The film with the food units thereon and a top film over the units is then subjected to vacuum and the top and the bottom films sealed. Alternately the package may be back-filled with oxygen-free gas prior to being sealed about the food unit. The disclosure includes also the steps of partially sealing food units between top and bottom films in a first chamber, back-filling with a substantially oxygen-free gas, then vacuumizing in a second chamber, and fully sealing the packages in a second chamber, or alternately back-filling with the oxygen-free gas before fully sealing.Type: GrantFiled: November 15, 1979Date of Patent: October 13, 1981Assignee: Armour and CompanyInventors: Burton R.
