  • Patent number: 9890438
    Abstract: An aluminum copper clad material has excellent bonding strength and includes an aluminum layer and a copper layer that are bonded without a nickel layer interposed therebetween. The aluminum layer and the copper layer are diffusion-bonded via an Al—Cu intermetallic compound layer. The copper layer satisfies Dcs?0.5×Dcc, where Dcc represents the average crystal grain size of crystal grains in a central portion in the thickness direction of the copper layer, and Dcs represents the average crystal grain size of an interface adjacent portion C2 in the copper layer that is about 0.5 ?m apart from the interface between the copper layer and the intermetallic compound layer. The intermetallic compound layer has an average thickness of about 0.5 ?m to about 10 ?m.

  • Patent number: 8800794
    Abstract: A biaxially drawn, blow-molded bottle and its preform comprise at least a layer of a gas barrier material laminated inside the PET resin layers, a functional portion having a screw thread raised spirally in the upper portion of neck and also having a stop ring disposed under the screw thread, and a neck ring disposed at the lower end of the neck. In these preform and bottle, the leading edge of the gas barrier layer is positioned at a half height of the neck ring where the most advanced front of the leading edge neither reaches a half height of the stop ring nor extends to the functional portion. It is intended here that the neck would not be affected by the shrinking deformation caused by the existence of the gas barrier layer in the functional portion of the neck, which is treated for thermal crystallization.

  • Patent number: 8524340
    Abstract: The preform of the biaxially drawn, blow-molded bottle comprises polyethylene terephthalate layers 2 and at least a gas barrier layer 3 laminated with the polyethylene terephthalate layers. The gas barrier layer 3 extends downward from a level halfway to the height of the neck 4 including the neck ring 5, or at least from above the neck ring 5, down virtually to the lower end of body 6. The gas barrier layer 3 inside the wall of the neck 4 has an average thickness corresponding to a third (?) or less of the maximum thickness of the gas barrier layer 3 inside the wall of the body 6, allowing most of the gas barrier material to be located in the wall of the body 6. Thus, the gas barrier material is effectively utilized, and in the case of the heat-resistant bottle, the neck has the predetermined dimensions without fail after the whitening treatment.

  • Patent number: 7464941
    Abstract: A sealing mechanism comprises a support member forming part of the semiconductor producing apparatus which has a vacuum chamber, a rotation shaft rotatably received in the support member, and at least three seal rings axially spaced apart from each other between the support member and the rotation shaft to form a first fluid chamber close to the atmosphere and a second fluid chamber close to the vacuum chamber. The first fluid chamber is vacuumized to have a first pressure, and the second fluid chamber is also vacuumized to have a second pressure which is lower than the first pressure. The first and second fluid chambers work together to enhance the sealing performance of the sealing mechanism.
