Abstract: A management system manages travel of at least one vehicle, and includes a vehicle and a travel management apparatus. The vehicle includes motors, a drive unit to move the vehicle by controlling the motors, a first communication circuit, and a control circuit. The travel management apparatus includes a signal processing circuit to generate an nth command for causing the vehicle to move from an n (n: a positive integer)th location to an (n+1)th location and a second communication circuit. When the vehicle arrives in a region defined for the (n+1)th location while moving from the nth location toward the (n+1)th location, the vehicle transmits a notification of arrival-in-region to the travel management apparatus. Upon receiving the notification of arrival-in-region, the travel management apparatus generates an (n+1)th command for causing the vehicle to move from the (n+1)th location to an (n+2)th location, and transmits it to the vehicle.

Abstract: A method is disclosed for cryopreserving living animal cells in immunoisolation membranes, including: (1) cutting out a living organ from an animal, (2) digesting the cutout organ into the discrete living animal cells and separating the discrete cells, (3) suspending the separated cells in a solution of sodium chloride containing sodium alginate and collagen, (4) forming microcapsules of the living animal cells by using the resulting suspension, (5) forming immunoisolation membranes around outer surfaces of the microcapsules of the living animal cells by covering the outer surfaces with alginate-(poly-L-lysine) and thereby obtaining the living animal cells enclosed in the immunoisolation membranes, (6) suspending the resulting living animal cells enclosed in the immunocapsules in a cell damage-preventing solution, and (7) immediately freezing the thus obtained suspension with liquid nitrogen.

Abstract: The present invention discloses a cut wire method of producing a ferrous shot and a cut-wire type ferrous shot for shot-blasting having a hardness of Hv 200 to 300 and a low work hardening ability. Further, the present invention describes a process of using a cut-wire type ferrous shots, comprising preparing the cut-wire type ferrous shots and a ferrous object and projecting the shots to the ferrous object to remove foreign material from the ferrous object.
