摘要:
A bonding member, which can achieve a sufficient degree of vacuum without forming a gap caused by air bubbles that have been released out through the surface of the bonding member, a bonding method, an image display apparatus, and a manufacturing method therefor. The bonding member 92 of a strip has a first portion 92a and a second portion 92b. The first portion 92a has a uniform thickness t1. The second portion 92b has a smaller thickness t2 than the thickness t1 of the first portion 92a and constitutes a side plane of the bonding member 92. The second portion 92b also has a shape such that a convexity and a concavity alternate along a longitudinal direction of the bonding member 92.

In a method of making a vacuum vessel having a pair of plates including a face plate and a rear plate bonded to each other using a bonding member, a bonding member is applied to a periphery of at least one of a pair of plates, the plates are placed in contact with each other through the bonding member disposed therebetween, parts of sides of the plates are fastened to each other using a positioning jig made of bimetal, the plates are separated from each other by placing the plates in an atmosphere and by thermally deforming the positioning jig, and the plates are fixed to each other around the entire peripheries thereof using the bonding member by performing cooling so as to reduce thermal deformation of the positioning jig and making the plates contact each other through the bonding member disposed therebetween.
摘要:
Under a vacuum atmosphere, while keeping two members in contact with each other with a bonding material therebetween, one of the members is moved relative to the bonding surface in the horizontal direction, and the bonding material between the members is pressed. The surface oxide film of the bonding material, which is a low melting point metal, is thereby broken effectively, and highly hermetic bonding is performed.

摘要:
A bonding method using a bonding agent is provided, which has the steps of forming an underlayer on a first member, providing a bonding agent on the underlayer, forming a contact member, different from the bonding agent, on a second member, bringing the bonding agent into contact with the contact member so that the first member and the second member are bonded to each other. In the method described above, the wettability of the bonding agent to the underlayer is superior to that of the bonding agent to a surface of the first member before the underlayer is formed thereon, and the bondability of the bonding agent to the contact member is superior to that of the bonding agent to a surface of the second member before the contact member is formed thereon.
摘要:
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.
