Abstract: A collaboration system connected to the Internet includes a collaboration server and multiple clients. A redirect program is resident in a client and monitors a URL transition event, and if a URL transition event has occurred, the redirect program captures the URL transition event and permits a browser to cancel it. Thereafter, the URL is redirected to the collaboration server. In response to the URL transition event, the collaboration server obtains contents from a web server. Applets for synchronization is added to the obtained contents, and the resultant contents are then transmitted to the client. Since contents are constantly obtained through the collaboration server, client collaboration is implemented.

Abstract: By hiding at least blackened portions from outside to make visual confirmation thereof impossible, a fluorescent lamp keeps its clean outward appearance until its service life expires and insufficiency of luminance on ends of the fluorescent lamp is dissolved. The fluorescent lamp comprising a plurality of discharging electrodes in a glass tube, and wherein the glass tube comprises an illuminating glass tube portion coated at inner wall surfaces thereof with a fluorescent substance and functioning as an illuminating body, and auxiliary glass tube portions provided contiguous to the illuminating glass tube portion and hidden from outside by shielding members, and wherein the discharging electrodes are not provided in the illuminating glass tube portion but mounted in the auxiliary glass tube portions.

Abstract: A collaboration client's behavior is changed according to context while collaborating on an internet. An HTTP request from a customer-side browser is sent to a web server via an information terminal support server. The web server then sends context in response to the request to the customer-side web browser via the information terminal support server. The information terminal support server then checks the contents of the context, and when it is determined that there is agreement with a predetermined condition, a command is inserted into the context. Context without the command inserted is sent to the customer-side web browser, and context with the command inserted is sent to the agent-side web browser. A client program of the agent-side information terminal then reads the embedded command using an API possessed by a web browser and carries out processing in order to prohibit form submission and form alteration and conceal specific forms or fields in accordance with the contents of this command.
