Abstract: Resources for maintaining links are conserved by not using links that substantially cannot relay data. In a mobile communication system (10) for multilink communication in which a mobile station apparatus (20) carries out communication using a plurality of links, each of the links is a link relayed by respective base station apparatuses (30). Each base station apparatus (30) sends bandwidth information indicating the bandwidth that can be allocated by the base station apparatus (30) to the mobile station apparatus (20), and the mobile station apparatus (20) receives the bandwidth information that has been sent and stops use of the respective links based on the received bandwidth information.

Abstract: A high molecular weight aliphatic polyester copolymer, a high molecular weight aliphatic polyester copolymer containing polylactic acid; process for industrially producing these copolymers; composition of these copolymers; and various uses thereof. These copolymers have practical properties which make the copolymers moldable. They are free from the problem of plasticizer bleeding and can be degraded by microorganisms present in soils or water. They give moldings, such as sheets and films, which combine a sufficient strength with tear resistance. When the copolymers are ones having a branched structure, they give a molding having excellent mechanical properties. The moldings obtained from compositions containing either of these copolymers are excellent in elongation and biodegradability and have a satisfactory balanc therebetween. In particular, blending with one or more other biodegradable resins gives a molding having better moldability.

Abstract: In a process for producing hydrated iron oxide which comprises the steps of adding an aqueous alkali solution to an aqueous solution of a ferrous salt in an amount no more than a neutralizing equivalent amount with respect to said ferrous salt, oxidizing the resulting ferrous hydroxide containing suspension to produce the seed crystals of hydrated iron oxide and subsequently supplying an additional amount of alkali and oxidizing the hydrated iron oxide to grow, sulfurous acid or a sulfite is added to either the aqueous ferrous salt solution or the aqueous alkali solution or the suspension containing ferrous hydroxide before the oxidation of ferrous hydroxide starts. The resulting hydrated iron oxide may be used as a raw material to produce berthollide, maghemite or a cobalt-doped ferromagnetic iron oxide.
