Abstract: There are provided a microporous film for an electric storage device separator, which can increase energy density and power density when used in an electric storage device, and which is excellent in handling properties in a processing step to the electric storage device, as well as an electric storage device separator and an electric storage device, using the microporous film. Specifically, provided is a microporous film for an electric storage device separator, characterized by including a porosity of 70% or more, a strength of 40 MPa or more in a longitudinal direction, an average pore size of from 40 to 400 nm, anuclear pores, and exhibiting biaxial orientation.

Abstract: It is possible to detect communication partner state information between edge nodes without using a broker. Additional information is needed to achieve the aforementioned object.

Abstract: A1 A communication system comprises obtaining a corresponding dynamic address by sending an identifier to a mapping notification system which stores a pair of an identifier and a dynamic address; and determining whether or not a dynamic address stored in the mapping notification system is correct by accessing other communication node to which the dynamic address obtained by the obtaining means is assigned. The system also compares the identifier sent to the mapping notification system and a reply for the access to the communication node. If the system determines that the address is not correct, the obtaining process and determination process are executed again, an execution of a process to be executed after the determination process is stopped, or a control process for preventing from sending back a reply of the address from the mapping notification system is executed.

Abstract: A microporous polypropylene film where film formability is improved in accordance with a ?-crystal technique which allows microporous films to be continuously manufactured at low cost is disclosed. In addition, a microporous polypropylene film of which the specific gravity is further reduced is provided. Furthermore, a microporous polypropylene film with a significantly high permeability is provided. In addition, manufacturing methods for these microporous polypropylene films are provided.

Abstract: The originator is made to discover the communication node specified by the receiver as the destination following the movement of the receiver among the communication nodes.

Abstract: In a network where host reachability is accomplished by relating a static identifier to a dynamic address, the live/death of a communication node and reachability are confirmed by using a sign and countersign.

Abstract: A communication system includes a station-side terminal apparatus and multiple subscriber-side terminal apparatuses connected to the station-side terminal apparatus. The station-side terminal apparatus is configured to, in response to receipt of a packet from a subscriber-side terminal apparatus, a packet indicating whether data distribution is required, identify the subscriber-side terminal apparatus that has transmitted the packet, and transmit a packet indicating an address for which whether the transfer of distribution data is required is designated to the subscriber-side terminal apparatus based on whether data distribution is required.

Abstract: Provided by the present invention are (1) a dry toner excellent in powder flowability and transferability when formed as a small-particle-size toner; (2) a dry toner excellent in any one of heat storage stability, low-temperature fixing property and anti-hot offset property; (3) a dry toner excellent in gloss exhibition when an image is formed by a full color copying machine; and (4) a dry toner which does not need application of an oil to a heat roll. Described specifically, provided by the present invention is a dry toner comprising a toner binder and a colorant, wherein the toner has a Wadell's practical sphericity ranging from 0.90 to 1.00, the toner binder contains a high-molecular-weight condensation resin (A) and a low-molecular-weight condensation resin (B), a ratio (MnA/MnB) of the number average molecular weight (MnA) of the resin (A) to the number average molecular weight (MnB) of the resin (B) is at least 1.

Abstract: A toner comprising a toner binder and a colorant, composed of resin particles produced by causing an extension reaction and/or crosslinking reaction of a dispersion formed of a reactive group-containing prepolymer (&agr;) contained in an aqueous medium with an extension agent and/or a crosslinking agent (&bgr;). The toner has a Wadell practical sphericity of 0.90 to 1.00 and is superior in fluidity, transferability, the storage stability under heat, low temperature fixing ability and hot offset resistance.
