Patent JP-2002539931-A (JP)
IPC: B01D29/11
Filed: 2000-03-29
Abstract: Filter cartridges may have a core element formed of a non-filtering, self-supporting non-woven mass of indefinite length continuous synthetic polymeric core fibers, and at least one annular filtration zone layer formed of a mass of non-woven indefinite length continuous synthetic polymeric filtration fibers. The non-woven core element is most preferably formed in situ during filter cartridge manufacturing by melt-blowing synthetic polymeric core fiber streams toward a forming mandrel. The non-woven core element is completely solidified prior to the filtration zone fibers being melt-blown thereon so that the core and filtration fibers are predominantly mechanically interlocked with one another, instead of being melt-bonded thereto. Filter cartridges of predetermined length may be cut from an upstream filter cartridge preform of indefinite length by subjecting the preform to forced cooling air to thereby minimize (if not eliminate entirely) significant filter cartridge shrinkage over time. In addition, a cutter assembly may be mounted laterally of the preform, but is capable of rate-synchronized longitudinal movement with the preform during its cutting operation.

IPC: G06F3/0488
Filed: 2000-05-24
Abstract: A system for capturing an electronic message is disclosed. The system includes a printer, a sensing device and a computer system. The printer prints on a substrate user information visible to a user and coded tags invisible to the user. Each coded tag encodes an identity unique to the substrate and a location of the coded tag on the substrate. The user information defines a message area on the substrate. The sensing device senses the coded tags on the substrate when the sensing device is moved relative to the substrate. The computer system electronically captures a message composed with the sensing device via movement of the sensing device relative to the message area, the computer system using the identity of the substrate and a sequence of respective locations of coded tags sensed by the sensing device for determining the movement relative to the message area and the message.

Title: Internet facsimile equipment and complementing method for mail address
Inventor: TANIMOTO YOSHIFUMI
IPC: H04N1/00
Filed: 2001-01-16
Abstract: PROBLEM TO BE SOLVED: To provide an Internet facsimile equipment and a complementing method which can complement the input of a mail address. SOLUTION: When a mail address inputted through an operation part 16 has no domain name, 'at mark' and the domain name of a FAX server 1 are added. Consequently, when Internet FAX transmission to a recipient's mail address having the same domain name, for example, in the same company is performed, the whole mail address need not be inputted. Therefore, even when the mail address inputted from the operation part 16 has no domain name, the mail address can be complemented and the Internet FAX transmission can be performed. Consequently, the part of the mail address after 'at mark' need not be inputted through the operation part 16.
