Abstract:
An oven is provided for curing or reflowing compounds on objects, such as lead frames or other substrates. The oven comprises a heating chamber, a heating assembly mounted in thermal communication with the heating chamber to provide heat thereto, and a support assembly for supporting the object in the heating chamber for heating. The heating assembly and support assembly are configured to be movable relative to one another for controllably positioning the object at variable distances with respect to the heating assembly. Heating of the object according to a heating profile can thus be achieved by controlled heating of the object at different temperatures by positioning the object at different distances with respect to the heating assembly during the heating process although there is a single heating zone.

Network users are authorized individual access during a log-on session to encrypted content on content media at the user without the necessity of individualizing the content media for the particular user. The content may comprise multimedia data. The content media, which may be mass produced and distributed, includes a computer program which generates a unique configuration identifier upon instantiation of the program to begin a user access session. The program creates a virtual directory structure for the content that is uniquely determined for that session by the configuration identifier. The configuration identifier is uploaded to a remote server which uses the configuration identifier with other information identifying the content media and the user authorize user access. The remote server creates and downloads to a browser of the user an encrypted message containing URLs for accessing the content in the virtual directory structure and containing transformations of a decryption algorithm and decryption keys for the encrypted content. Encrypted multimedia content selected by the user is stored in a temporary file, decrypted in a moving time window, and rendered After rendering, the decrypted portion of the temporary file is scrambled to preclude further access.

Abstract:
The present utility model relates to a fastener for cord comprising a cord lock mounted on a cord of an article for locking the cord, characterized in that said cord lock has a engaging portion which is provided with a hollow central zone having an inner diameter, said fastener for cord further has a base fixed on said article, a convex portion is arranged on said base for engaging with said central zone in a manner of snap-fastening, the inner diameter of said central zone is slightly smaller than the outer diameter of the convex portion on said base so as to make the central zone engaged, in a manner of snap-fastening, with said base. The present utility model is available for fastening an article (such as a fixer or bottom on a cord) so as to avoid inconveniency brought to users by the article.
Abstract:
The present utility model relates to a fastener for cord, wherein said fastener comprises a base body 1 and a holding portion 2 connected thereto, the holding portion 2 has a through hole 3 for receiving said cord, a slit 4 is arranged in the side wall of the through hole, and the side wall of the through hole is separated into a first part and a second part by means of said slit. With the fastener, the cord of an article can be fastened so as to retain if in the same position. In this way, even if the cord is relatively long, it can be simply fastened by means of the fastener to retain its stretched state, and it needn't to be rolled up while being out of use. Therefore, it is much more convenient for the users to use the cord again.
Abstract:
The present invention is directed to a fastener (1), includes a curved end (2) and a head away from the curved end (2), wherein an object can be hooked up at the curved end (2), the head being provided with a narrower passage (3) for a cord (6) to pass through and a wider passage (4) for a tape (7) to pass through, the cord (6) and the tape (7) being used to connect to the same subject or separately to different subjects.
