Patent number: 6851997Abstract: The present invention relates to a process for depositing a calcium getter thin film inside a system operating under vacuum. The process comprises the steps of introducing into the system under vacuum at least one evaporable getter device with an air-stable calcium compound. The system is evacuated until a pressure value P1 is reached. The system is then heated up to the calcium evaporation temperature of the stable compound. The system evacuation continues until a pressure value P2, which is lower than P1, is reached and the system is sealed. In a preferred embodiment, the heating step separates the two evacuation steps.Type: GrantFiled: November 14, 2002Date of Patent: February 8, 2005Assignee: SAES Getters S.p.A.Inventors: Corrado Carretti, Giorgio Longoni

Patent number: 6583559Abstract: A getter comprising a calcium-aluminum compound including about 39% to about 43% calcium by weight produces a calcium vapor when sufficiently heated. The calcium vapor can condense to form a calcium film on an inside surface of a sealed evacuated enclosure such as a CRT to getter reactive species from the enclosed volume. The calcium-aluminum compound, preferably CaAl2 powder, can be mixed with either nickel powder, titanium powder, or both.Type: GrantFiled: June 22, 2000Date of Patent: June 24, 2003Assignee: SAES Getter S.p.A.Inventors: Corrado Carretti, Luca Toia, Claudio Boffito

Patent number: 6100627Abstract: A Field Emitter Device (FED) having a substantially reducing atmosphere is described. The atmosphere in a FED can be maintained substantially free of oxidizing gases and includes a partial pressure of hydrogen between about 1.times.10.sup.-7 millibar (mbar) and 1.times.10.sup.-3 mbar. In one embodiment, a non-evaporable getter material previously charged with hydrogen gas is placed inside the FED before the FED is sealed. The non-evaporable getter material can be charged by exposure to hydrogen gas at a pressure between about 1.times.10.sup.-4 and about 2 bar. Subsequently, the components forming the FED are sealed, and the FED is evacuated and hermetically sealed to the outside atmosphere.Type: GrantFiled: June 5, 1997Date of Patent: August 8, 2000Assignee: SAES Getters S.p.A.Inventors: Corrado Carretti, Bruno Ferrario
