Title: System and method for the transmission, storage and retrieval of authenticated documents
Inventor: BISBEE STEPHEN F
IPC: G06Q20/00
Filed: 2003-07-17
Abstract: Certificate Status Service that is configurable, directed, and able to retrieve status from any approved Certification Authority (CA) is disclosed. The CSS may be used by a Trusted Custodial Utility (TCU) and comparable systems or applications whose roles are validating the right of an individual to perform a requisite action, the authenticity of submitted electronic information objects, and the status of authentication certificates used in digital signature verification and user authentication processes. The validity check on authentication certificates is performed by querying an issuing CA. Traditionally, to create a trusted Public Key Infrastructure (PKI) needed to validate certificates, complex relationships are formed by cross- certification among CAs or by use of PKI bridges. The PKI and CA interoperability problem is addressed from a different point of view, with a focus on establishing a trust environment suitable for the creation, execution, maintenance, transfer, retrieval and destruction of electronic original information objects that may also be transferable records (ownership may change hands). A TCU is concerned only with a known set of "approved CAs" although they may support a multitude of business environments, and within that set of CAs, only with those certificates that are associated with TCU user accounts. Building PKI/CA trusted relationships is not required as the CSS achieves a trusted environment by querying only approved CAs and maintaining caches of valid certificates' status.

Title: Method of cutting multilayer body, method of forming multilayer container, and multilayer formed product
Inventor: HARUTA TOMOAKI
IPC: B26D7/27
Filed: 2003-07-25
Abstract: When a multilayer body is cut, an intermediate layer at an end face of the multilayer body is stably covered by a surface resin layer. A method of cutting a multilayer body is characterized as follows. When at least one layer of resin that structures a multilater body (10) is in a melted state, a cutter blade (15) is made to cut for a predetermined amount into the multilayer body (10) supported by a blade-receiving portion (14). Then, as an upper layer breaks into a lower layer, individual layers (11, 12, 13) are extended, compressed, and deformed, so that the layers become thin. A portion (S), or the compressed thin portion, is cut by pressing the cutter blade (15) on the portion (S) until the blade butts against the blade-receiving portion (14), and the intermediate layer (11) and each of the surface resin layers (12, 13) are converged at a butt portion (A) where the cutter blade (15) and the blade receiving-portion (14) butt against each other.

Title: A packaged semiconductor with coated leads and method therefore
Inventor: VO NHAT D
IPC: H01L23/495
Filed: 2003-07-25
Abstract: A semiconductor die (425) is housed in a package body (115). Leads (110), which are electrically coupled to the semiconductor die, extend from the package body and are for connecting to a printed circuit board (510) or other device. The leads are coated with a material that protects the leads from oxidation. The coating (430) is compatible with solder techniques that are commonly used to attach packaged semiconductors to a printed circuit board. In some examples, the coating is removable, after drying, at temperatures below one hundred eighty degrees Celsius. This allows for solder processes, which are typically at least 180°C, to remove the coating thereby exposing the leads, which has been protected from oxidation, so that it can be soldered to the printed circuit board. In some examples, the coating material includes an organic material. In some examples, the coating material is an organic solderability preservative (OSP).

Title: Fast coupling unit with integrated check valve
Inventor: MORETTI ERMINIO
IPC: F16K15/02
Filed: 2004-05-13
Abstract: The invention relates to a fast coupling unit (1) for lines conducting free-flowing media, in which a check valve (5) is integrated for controlling the pressure of the medium or venting the lines conducting the medium. Said check valve (5) is arranged in a secondary branch (4) that is opened outwards and extends from the main line of the fast coupling unit (1). Its valve body (10) is moved by a restoring force from its position blocking the passage of the medium into its position allowing the passage of the medium by means of a valve lifter (12) that can be accessed from the outside. The secondary branch (4) is at the same time the valve housing (4) of the check valve (5). The valve body (10) that can be axially moved in the valve housing (4) is configured in an integral manner and has a valve cone (11), the valve seat of which is configured as a corresponding conical surface (16) in a hollow counterpiece (17) sealingly inserted in the open end of the secondary branch (4) or valve housing (4) against the inner wall thereof. The check valve (5) has the advantage that it consists of few individual parts, which can be produced and mounted in a simple and economical manner and are preferably made of plastic. This enables greater air- tightness of the valve when it is closed.
