Publication number: 20210283546Abstract: A filter has a primary structure composed of a first material with a relatively high melting point; a secondary structure composed of a second material with a lower melting point than the first material; and voids. This configuration provides the filter with controllable breathability. A gas-adsorption device including the filter can control the gas permeability rate. A vacuum insulation material including the gas-adsorption device enables the gas adsorber to selectively adsorb non-condensable gas from water-vapor-containing gas. As a result, the vacuum insulation material can be maintained at low pressure for a long period of time, thereby maintaining high insulation performance.Type: ApplicationFiled: November 22, 2017Publication date: September 16, 2021Inventor: Masamichi HASHIDA

Patent number: 8821618Abstract: A gas-adsorbing member is charged in low gas-permeable container (7) through its opening portion, wherein low gas-permeable container (7) is constituted by a hollow cylindrical metal member which is opened at its one end and is sealed at its other end and, also, has body portion (9) extending from the one end to the other end thereof such that the length of the body portion is equal to or larger than the maximum width of the end portions. Then, a sealing member is installed within the opening portion and near the opening portion. Then, the sealing member is molten by being heated. Thereafter, the sealing member within the opening portion is cooled to be solidified, thereby attaining sealing of the opening portion. Thus, it is possible to provide a gas-adsorbing-device fabricating method capable of suppressing degradations of the gas-adsorbing member and capable of reducing the fabrication costs.Type: GrantFiled: March 23, 2010Date of Patent: September 2, 2014Assignee: Panasonic CorporationInventor: Masamichi Hashida

Patent number: 8778057Abstract: Includes gas adsorption device (1) in which gas adsorbent (3) is decompression-sealed by first package (4) with poor gas permeability, and second package (2) with poor gas permeability. Second package (2) is at least partially flexible. Air that is a gas that gas adsorbent (3) can adsorb is filled between gas adsorption device (1) and second package (2). In this configuration, gas adsorbent (3) adsorbs air when first package (4) is damaged, and thus a pressure inside second package (2) reduces. Due to this pressure reduction, the shape or dimension of second package (2) changes. Any damage to first package (4), i.e., any degradation in adsorption capacity of gas adsorption device (1), can thus be determined by confirming this change.Type: GrantFiled: March 9, 2011Date of Patent: July 15, 2014Assignee: Panasonic CorporationInventor: Masamichi Hashida

Patent number: 8308852Abstract: A jacket material into which a gas adsorbing device and core material are inserted is decompressed in a vacuum chamber, the opening is sealed, and then the jacket material is exposed to the atmosphere. In the atmospheric pressure, a pressure of about 1 atm which is equivalent to the pressure difference between the inside and outside is applied to the jacket material of the heat insulator. The jacket material is made of a plastic laminated film and is deformed by pressure. A protruding portion is plunged into a container to drill through holes, and a gas adsorbent in the container communicates with the inside of the jacket material. Thus, both during holding and in applying to the vacuum heat insulator, the gas adsorbent can be applied to the vacuum heat insulator without degradation, and the high degree of vacuum can be kept for a long time.Type: GrantFiled: June 8, 2010Date of Patent: November 13, 2012Assignee: Panasonic CorporationInventors: Masamichi Hashida, Kazutaka Uekado, Akiko Yuasa
