Abstract: A memory system includes a memory device including memory chips and a controller. The controller includes first processors configured to perform first processing of network packets in at least one of a network layer and a transport layer of a network protocol, and second processors configured to perform second processing with respect to the memory chips. The controller is configured to extract tag information from a header of a network packet, select one of the first processors associated with a first memory chip that is identified based on the tag information, and control the selected one of the first processors to perform the first processing with respect to the network packet, which causes one of the second processors associated with the first memory chip to perform the second processing based on a payload of the network packet.

Abstract: A lifting magnet including a plurality of electromagnetic coils that are disposed in a nesting arrangement and capable of being independently ON/OFF-controlled and voltage-controlled. By using the plurality of electromagnetic coils in a selective or appropriately combined manner, the lifting magnet secures a sufficient magnetic flux penetration depth during conveyance of steel plates, and can easily and highly precisely control the magnetic flux penetration depth in accordance with the number of steel plates to be lifted.

Abstract: A method of forming a thermoplastic polyester series foamed material having a thickness of at least 3 mm and an apparent density of from 0.05 to 0.7 g/cm.sup.3, wherein the crystallinity of the resin in the surface portion within 0.5 mm from the surface of the foamed material is not more than 30% and at least 1% lower than the crystallinity of the resin in the central portion of the foamed material.

Abstract: A thermoplastic polyester series foamed material having a thickness of at least 3 mm and an apparent density of from 0.05 to 0.7 g/cm.sup.3 is diclosed, wherein the crystallinity of the resin in the surface portion within 0.5 mm from the surface of the foamed material is not more than 30% and at least 1% lower than the crystallinity of the resin in the central portion of the foamed material.

Abstract: A process of producing a thermoplastic polyester series resin foamed material is disclosed, which comprises heating and further foaming a thermoplastic polyester resin foamed material having a crystallinity of not higher than 30% by bringing it into contact with water or steam of at least 60.degree. C. and then heating the foamed material by bringing it into contact with a heating medium other than water of at least 100.degree. C. to further foam the foamed material. A process of producing a thermoplastic polyester series resin foamed material is also disclosed, which comprises heating and further foaming a thermoplastic polyester series resin foamed material having a crystallinity of not higher than 30% by bringing it into contact with water or steam of at least 60.degree. C., heating and further foaming the foamed material by bringing it into contact with a heating medium other than water of at least 100.degree. C., and molding the foamed material by a mold.

Abstract: A process for producing a thermoplastic polyester resin foam comprising melting a thermoplastic polyester resin, mixing the molten resin with a blowing agent and extruding the mixture into a low-pressure zone to carry out expansion molding, characterized in that a compound having two or more acid anhydride groups per molecule, optionally together with a compound of a metal of Group I, II or III elements of the Periodic Table is added to the thermoplastic polyester resin. There is also disclosed a process for producing a thermoplastic polyester resin foam comprising cooling a high-temperature foam immediately after expansion and then re-heating the foam. Further, a thermoplastic polyester resin foam sheet and a food container prepared from the foam sheet are also disclosed.
