Patent number: 6619071Abstract: In an adsorption-type refrigerating apparatus, an adsorber includes therein an adsorbent having a temperature-dependent characteristic in which an amount adsorbed in an adsorption step is larger than an amount adsorbed in a desorption step, even when a vapor pressure rate in the adsorption step is equal to or lower than a vapor pressure rate in the desorption step. Therefore, even when the cooling temperature of outside air for cooling the adsorbent increases, a sufficient cooling capacity can be obtained. In addition, a difference between the amount adsorbed in the adsorption step and the amount adsorbed in the desorption step can be made larger.Type: GrantFiled: June 6, 2002Date of Patent: September 16, 2003Assignee: Denso CorporationInventors: Hideaki Sato, Katsuya Ishii, Atsushi Kosaka, Shigeo Numazawa, Seiji Inoue, Kouji Inagaki, Kazuhisa Yano, Norihiko Setoyama, Yoshiaki Fukuyama

Patent number: 6194650Abstract: A coated material comprising a substrate which has micropores and a reaction product coated thereon along the surface configuration of the substrate and an inner wall of the micropores thereof. The coated material is preferably produced by performing a supercritical coating step wherein a reaction precursor is dissolved in a supercritical fluid to form a precursor fluid and then the precursor fluid is brought into contact with a substrate in the presence with a reaction initiator to allow a reaction between the reaction precursor and the reaction initiator, thereby coating a reaction product onto the substrate.Type: GrantFiled: April 27, 1999Date of Patent: February 27, 2001Assignee: Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Hiroaki Wakayama, Yoshiaki Fukushima, Narihito Tatsuda, Yoshitsugu Kojima, Osami Kamigaito, Yasutomo Goto, Shinji Inagaki, Kenichirou Suzuki, Megumi Sasaki, Hiroaki Hayashi, Kazuo Higuchi, Norihiko Setoyama
