Publication number: 20240317427Abstract: To control a mobile node group that performs a formation flight, mobile nodes constituting the mobile node group and a ground station that wirelessly communicates with each of the mobile nodes are included. The mobile nodes are classified into a follower mobile node and a leader mobile node that collects information on the follower mobile node and controls the follower mobile node. The mobile nodes wirelessly communicate with one another based on beamforming or MIMO. Based on an installed on-board processor, the leader mobile node controls the follower mobile node, and the mobile node controls a position or an attitude of the mobile node itself for performing the formation flight. The ground station performs link control of the wireless communication with the mobile node or link control of the wireless communication between the mobile nodes, and control of selecting any ground station that wirelessly communicates with the mobile node.Type: ApplicationFiled: May 16, 2022Publication date: September 26, 2024Applicant: NATIONAL INSTITUTE OF INFORMATION AND COMMUNICATIONS TECHNOLOGYInventors: Yuma ABE, Hideaki KOTAKE, Morio TOYOSHIMA

Patent number: 4907709Abstract: A combination of a bottle (1) and a closure (2) for containing a drink, having an improved sealability. The bottle (1) is produced by a blow-molding process with a resin comprised mainly of a polyethylene terephthalate, so that a bottle neck (3) is in a non-crystalline state while a bottle body (5) is given an improved heat durability by a bi-axial orientation followed by a heat treatment for relaxation. The closure (2) is made of a thermoplastic resin such a a polyolefin and provided with a top wall and a side wall having a thread (7) on the inner surface (9) thereof corresponding to a thread (4) on the outer surface (12) of the bottle neck (3).Type: GrantFiled: November 10, 1988Date of Patent: March 13, 1990Assignee: Dainippon Ink and Chemicals, Inc.Inventors: Morio Abe, Ichiro Yokota

Patent number: 4861633Abstract: A superior cylindrical filter having a long filtration life is provided, which filter is obtained by using interlaced filaments comprising 20% by weight or more of hot-melt-adhesive composite filaments composed of plurality of components having a melting point difference of 20.degree. C. or more and having two or more interlaced portions per meter of which the interlacing strength is 15.times.D mg or more, wound up on a core material in a cylindrical form under a tension of 15.times.D mg or less, the contact points of the interlaced filaments being bonded by melt-adhesion of the low melting component of the composite filaments.Type: GrantFiled: May 19, 1988Date of Patent: August 29, 1989Assignee: Chisso CorporationInventor: Morio Abe

Patent number: 4840846Abstract: A heat-adhesive composite fiber consisting of core portion and sheath portion, the core portion being of the side-by-side type composite structure comprising two core components of different polypropylene base polymers at a composite ratio of 1:2 to 2:1, one of the core components having a Q value, expressed in terms of the weight-average molecular weight/the number-average molecular weight, equal to or higher than 6 and the other having a Q value equal to or lower than 5, and the sheath portion meeting at least the requirements that it should comprise a sheath component of a polyethylene base polymer having a melting point lower by at least 20.degree. C. than the lower one of the melting points of the two core components, and it should cover the core portion in a proportion of 25 to 55% by weight based on the total weight of it and the core portion.Type: GrantFiled: September 10, 1987Date of Patent: June 20, 1989Assignee: Chisso CorporationInventors: Shozo Ejima, Taizo Sugihara, Morio Abe

Patent number: 4818587Abstract: Nonwoven fabrics contain at least 30% by weight of heat-adhesive composite fibers consisting of core portion and sheath portion, said core portion being of the side-by-side type composite structure comprising two core components of different polypropylene base polymers in a composite ratio of 1:2 to 2:1, one of said core components having a Q value, expressed in terms of the weight-average molecular weight/the number-average molecular weight, equal to or higher than 6 and the other having a Q value equal to or lower than 5, and said sheath portion meeting at least the requirement that it should comprise a sheath component of a polyethylene base polymer having a melting point lower by at least 20.degree. C. than the lower one of the melting points of said two core components. The nonwoven fabrics are bulky and soft due to the crimps of the heat-adhesive composite fibers resultant from the core portion and are stabilized by the inter-fiber bonds of the sheath portion.Type: GrantFiled: October 15, 1987Date of Patent: April 4, 1989Assignee: Chisso CorporationInventors: Shozo Ejima, Taizo Sugihara, Morio Abe
