Abstract: The present invention provides the cooling apparatus assembly of the LED lighting device, consisting of a LED lighting apparatus mounting plate (300), heat pipes (400) that are secured at the opposite surface to the surface where the lighting apparatus is fixed, and heat radiation pins (500) that are mechanically pressed and fixed to the heat pipes. On the mounting plate (300) of said LED lighting apparatus, at least one fixing hole (320) is provided and the heat pipes (400) are fixed rearward by the binding bolt (310), perpendicular to the mounting plate. And the one end of the heat pipes (400) is comprised of a adherence pipe (441) and an inner pipe (442), where the adherence pipe(441), having circumferential uneven or rugged portion(451) at the outer surface, is positioned at the inner side of the heat pipes, and where the inner pipe (442), having a nut screw (410) to receive the binding bolt (310), is inserted into the adherence pipe (441) with pressing force.

Abstract: A client terminal 3 can generate PAdES while performing communication with a long-term signature server 2 without delivering a PDF document and a secret key used in an electronic signature to the long-term signature server 2. PAdES is a long-term signature format which is specified for a PDF file. The client terminal 3 transmits CAdES with the electronic signature before time stamp issuance to the long-term signature server 2 to request to issue a time stamp to CAdES. The client terminal 3 requests the long-term signature server 2 to collect verification information, acquires the verification information, further generates information for confirming unfalsification of a signed PDF document and the verification information therefrom, and transmits the information to the long-term signature server 2 to request to generate DTS. With the above, it is possible to perform a long-term signature while retaining confidential information on a user side.
