Patent number: 11291949Abstract: A carbon dioxide separation recovery method includes: bringing a particulate carbon dioxide adsorbent and a treatment target gas containing carbon dioxide into contact with each other to make the carbon dioxide adsorbent adsorb the carbon dioxide contained in the treatment target gas; and bringing the carbon dioxide adsorbent which has adsorbed the carbon dioxide and superheated steam into contact with each other to desorb the carbon dioxide from the carbon dioxide adsorbent and thereby regenerate the carbon dioxide adsorbent, and recovering the desorbed carbon dioxide. A saturation temperature of the superheated steam which is brought into contact with the carbon dioxide adsorbent is not more than a temperature of the carbon dioxide adsorbent which contacts the superheated steam. The regenerated carbon dioxide adsorbent is utilized for adsorption of the carbon dioxide again without being subjected to a drying step.Type: GrantFiled: October 29, 2019Date of Patent: April 5, 2022Assignees: RESEARCH INSTITUTE OF INNOVATIVE TECHNOLOGY FOR THE EARTH, KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Shin Yamamoto, Hidetaka Yamada, Katsunori Yogo, Shohei Nishibe, Kazuo Tanaka, Katsuhiro Yoshizawa, Takeshi Okumura, Ryohei Numaguchi

Patent number: 11285634Abstract: When a veneer conveyed out by a discharging conveyor is a product veneer, a sorting apparatus is rotationally driven to pierce the product veneer with needle-like bodies by a guide member and a push-up member (a rolling bearing). When the veneer conveyed out by the discharging conveyor is a trash veneer, the sorting apparatus is rotationally driven so that the trash veneer is not pierced by the needle-like body. With this configuration, the progress of the abrasion of the needle-like bodies can be delayed as compared with the configuration in which the product veneer and the trash veneer are both pierced by the needle-like body. As a result, the time to replace the needle-like bodies can be extended, whereby the running cost can be reduced.Type: GrantFiled: August 11, 2018Date of Patent: March 29, 2022Assignee: MEINAN MACHINERY WORKS, INC.Inventors: Fumitoshi Ikemoto, Hidetaka Yamada

Patent number: 11180338Abstract: An apparatus for moving veneer includes a leaf spring having at lower tip end thereof sharpened edges and configured to move a veneer sheet toward its preceding stationary veneer sheet. Further lowering the leaf spring with the tip end already stuck in the veneer sheet causes the leaf spring to be resiliently deformed, which creates a force due to restoring force of the leaf spring that acts on the veneer sheet to move toward the preceding veneer sheet thereby to reduce or eliminate a gap between the two veneer sheets. Additional leaf spring movable with the above leaf spring and configured to hold the preceding veneer sheet during the movement may be provided.Type: GrantFiled: October 22, 2019Date of Patent: November 23, 2021Assignee: Meinan Machinery Works, Inc.Inventor: Hidetaka Yamada
