摘要:
To conduct conversation without confusion in a virtual space while sharing a plurality of topics, send origin channel #CHOCOA, destination channel #meeting and message sending conditions are correlated and given to a chat server or chat client. If, for example, “USER1, USER3, USER4” are designated as sending conditions, only messages from designated users are sent from message origin channel #CHOCOA to destination channel #meeting. Meanwhile, messages from “USER1, USER3, USER4” can be displayed on message origin channel #CHOCOA or not displayed.

A surface-treated steel sheet has a zinc-based or an aluminum-based plated steel sheet, a surface-treatment coating being formed on the surface of the zinc-based or aluminum-based steel sheet by applying and drying a surface treatment coating composition thereon, and a top coating being formed by applying and drying a coating composition for top coating on the surface-treatment coating. The surface treatment coating composition contains a water-epoxy resin dispersion, a water dispersed polyurethane resin, a silane coupling agent, and phosphoric acid and/or a hexafluorometal acid. The coating composition for a top coating contains a high molecular weight epoxy group-containing resin average molecular weight of 6,000 to 20,000.

A notification is sent to a group of information terminals that conduct simultaneous communication by participating in a channel. The status change notification system includes a database DB and monitoring means 1. The DB is disposed outside the channel. The monitoring means 1 monitors an occurrence of a status change in the DB, and generates a notification of a status change when a status change occurs. At least one of the group of information terminals includes notifying means 3. The notifying means 3 receives a notification of status change from the monitoring means 1. The notifying means sends the notification to other of the group of information terminals to notify of the status change in a broadcasting manner.
摘要:
A communication management system is adapted for a chat system provided in a computer network including a plurality of client workstations and a server computer linked thereto. The communication management system includes a log file recognizing part which recognizes recognizing a log file produced at a predetermined channel of the chat system during a chat session between the plurality of client workstations and the server computer even when the client workstation of concern is not connected to the channel of the chat system. A storage part stores the log file recognized by the log file recognizing part. A log file output part transmits the log file, stored by the storage part, through the computer network to an external communication device provided outside the chat system, when a log file request transmitted by the external communication device is received by the log file output part.
摘要:
When actuation of an application program is received by a client, the client is connected with a chat server and participates in and registers at a channel, and attribute information, a number of times of statements or amount of statements in the registered channel is displayed, without a user's predetermined operation and a publicly known conversation process is executed. Thereafter, when designation of the displayed attribute information, number of times of statements or amount of statements is received, a channel where statements are possible is changed into a channel relating to the designation.

The invention relates to a thermosetting coating composition for precoated steel sheets which are required to have high hardness, good workability and stain resistance, to a precoated steel sheet having a film of the coating composition, and to a method for producing such precoated steel sheets. The coating composition for precoated steel sheets of the invention consists essentially of a polyol and contains a specific compound and a curing agent composed of polyisocyanate compounds added thereto, in which the curing agent is a mixture composed of a blocked polyisocyanate compound as obtained by blocking one or more polyisocyanate compounds selected from polyisocyanates of the following group (a) and their derivatives, and a blocked polyisocyanate compound as obtained by blocking one or more polyisocyanate compounds selected from polyisocyanates of the following group (b) and their derivatives:(a) 4,4'-diphenylmethane diisocyanate, isophorone diisocyanate, tolylene diisocyanate, xylylene diisocyanate, naphthalene-1,5-diisocyanate;(b) hexamethylene diisocyanate, trimethylhexamethylene diisocyanate, hydrogenated 4,4'-diphenylmethane diisocyanate, hydrogenated tolylene diisocyanate, hydrogenated xylylene diisocyanate.The coating composition forms a coating film having good workability, high hardness and good stain resistance.

In an image reading apparatus provided with a light source for illuminating an original, the light source includes a fluorescent lamp having a tube surface by means of which a part of a beam of light therefrom is condensed on the surface of the original by the optical action thereof, a line sensor for reading image information of the original and an optical device for causing image information of the original illuminated with the beam of light from the light source to be imaged on the line sensor.
摘要:
A client-server type network having at least two clients which execute the same kind of operation. The server and the clients are improved in order to realize addition or reduction in the number of clients. When the client is started, the fact that the client in under operation is recorded in the data base of the server. Since the addition of a client is automatically recorded in the server, the addition is easily facilitated. The server is provided with a client managing device for judging whether or not the client is under operation by polling. If the client is stopped due to a problem or the like, the fact is automatically recorded in the data base of the server. Therefore, it is also easy to eliminate the client from the data base of the server.
