The sealed housing includes a front plate (10), a back plate (20) and a plurality of side walls (90) affixed between the front plate and the back plate so that the front plate, the back plate and the side walls define an interspace region. The front plate and the back plate are preferably made from glass. The side walls are made from an Invar-36 alloy having a coefficient of thermal expansion similar to that of the glass.Type: GrantFiled: November 6, 2002Date of Patent: September 7, 2004Assignee: Hon Hai Precision Inc. Co., Ltd.Inventor: Ga-Lane Chen

Patent number: 6784613Abstract: A non-evaporating getter maintains the adsorbability for the residual gases, and in addition, secures sufficient characteristics particularly even when it experiences a high-temperature and low-vacuum condition in the fabrication process of a display unit. The non-evaporating getter includes a substrate having no function as a getter and a polycrystalline film arranged on the substrate which film contains Ti as the main component and has a host of voids in the interior thereof. A non-evaporating getter is made by forming a polycrystalline film containing Ti as the main component on the concavo-convex surface of the substrate which substrate has concavities and convexities on a surface thereof and has no function as a getter.Type: GrantFiled: August 16, 2002Date of Patent: August 31, 2004Assignee: Canon Kabushiki KaishaInventors: Masaki Tokioka, Mitsutoshi Hasegawa, Kazuya Shigeoka, Yutaka Arai

Patent number: 6774555Abstract: A CRT including an evacuated envelope with a color selection electrode assembly disposed within the envelope, and an internal magnetic shield (IMS) secured to the color selection electrode assembly, and having a replaceable getter attachment assembly comprising a mounting rail and replaceable getter portion. The mounting rail having a first portion with a coupling clip attached to the IMS and a second portion extending therefrom. The replaceable getter portion includes a first end extending from the mounting rail with a getter cup attached thereto and a second end detachably attached to the second portion of the mounting rail. The replaceable getter portion extends from the mounting rail to deposit a film of evaporated getter material therefrom within the envelope.Type: GrantFiled: May 3, 2002Date of Patent: August 10, 2004Assignee: Thomson Licensing S. A.Inventors: Mort Jay Nierenberg, Kelly Eugene Hamm, Douglas David Harding, Stephen Thomas Opresko, Hale Andrew Johnson

Publication number: 20040135505Abstract: In an image display device having in an airtight container an electron source and an image display member that receives electrons from the electron source, an evaporating getter and a non-evaporating getter are stacked in the airtight container. This makes it possible to maintain the vacuum level in the airtight container. The image display device thus obtains a prolonged life and a stable display operation.Type: ApplicationFiled: July 23, 2003Publication date: July 15, 2004Applicant: CANON KABUSHIKI KAISHAInventors: Mitsutoshi Hasegawa, Ihachiro Gofuku, Masaki Tokioka, Kazuya Shigeoka, Tokutaka Miura
