Patent number: 8679229Abstract: An adsorbent comprising a zeolite having a pore diameter of not less than 4.5 angstroms and not more than 7.3 angstroms as a principal component, which can adsorb xenon under ordinary temperatures and pressures or under ordinary temperatures and low xenon partial pressure, is used. In the xenon recovery method of the present invention, the adsorbent is communicated with a xenon-containing equipment, and xenon is adsorbed on the adsorbent and xenon is detached from the adsorbent. Thereby, xenon can be recovered, with efficiency, directly from used equipment in which xenon is enclosed under ordinary temperatures and pressures or under ordinary temperatures and low xenon partial pressure.Type: GrantFiled: August 26, 2010Date of Patent: March 25, 2014Assignee: Panasonic CorporationInventor: Akiko Yuasa

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

Patent number: 7833327Abstract: An adsorbent capable of adsorbing gas low in activity such as nitrogen is used, and a thermal insulator high in production efficiency and excellent in adiabatic performance is presented. A thermal insulator has an adsorbent, a core material, and an enveloping member. The adsorbent includes Li and solid matter of hardness of 5 or more. The gas adsorbing activity becomes very high, and for embodiment by evacuating to a certain degree of vacuum by using a vacuum pump, the remaining gas is adsorbed by the adsorbent of the invention to obtain a desired degree of vacuum, so that a thermal insulator of high production efficiency is obtained. Since the heat conductivity is decreased by adsorbing gas of low activity in the enveloping member, the adiabatic performance is enhanced.Type: GrantFiled: January 27, 2006Date of Patent: November 16, 2010Assignee: Panasonic CorporationInventors: Chie Hirai, Kazutaka Uekado, Akiko Yuasa
