Abstract: A communication apparatus is provided that reduces the operating time when a user requests delivery of a message that previously was not delivered. The controller detects when a message is not delivered and registers a group of addresses in a group registering area in a memory. The group of addresses includes addresses of each communication terminal detected that did not receive the message. When the user requests delivery of the message again, the controller sets all addresses included in the registered group as delivery addresses for the message.

Abstract: When a firewall receives, from a mobile terminal via the Internet, an access request which designates a URL including a http, a domain name containing a host name, a service name, a machine name, and a specific port number, the firewall outputs the request to a corresponding port of a relay server. The relay server sends an authentication page to the request source terminal to cause the user to input authentication data, and causes an authentication server to authenticate the request source user on the basis of the input authentication data. If authentication succeeds, the relay server checks whether the authenticated user can receive a service represented by the service name and machine name in the URL. If the user can receive the service, the relay server sets a session, and grants request/response communication between the mobile terminal of the request source and the request destination in the session.

Abstract: A process for the continuous production of cobalt-modified magnetic iron oxide. This process comprises carrying out a batchwise preliminary cobalt treatment by adding a magnetic iron oxide powder to an alkaline solution followed by the addition of a cobalt salt to cover the magnetic iron oxide powder with cobalt. A cobalt modification reaction is carried out continuously by passing the solution containing the preliminary cobalt-treated magnetic iron oxide powder under heat and pressure through a flow-type reaction vessel.

Abstract: A standard material for measuring immune complexes which is prepared by chemically binding immunoglobulin and/or its fragment with a complement and/or its derivative through the medium of a bifunctional reagent. By using the standard material, the standard curve which is used for measuring immune complexes existing in the blood is obtained.
