Abstract: An access plate mounted between the pipe bracket portion and either the service portion or the emergency portion of a railway freight brake control valve. Passageways are provided through the access plate, each passageway terminating in a respective access port along an end of the access plate. Openings extend through opposed sides of the access plate, intersecting respective access plate passageways. The openings on each side are sized and positioned to sealingly align with openings of the pipe bracket portion and either the emergency portion or the service portion. The openings on the pipe bracket portion, emergency portion and service portion connect to passageways communicating to the brake pipe, the brake cylinder retaining valve, the brake cylinder, the emergency reservoir and the auxiliary reservoir. A housing may be attached to the pipe bracket portion to connect to the access ports, such housing preferably having a valve means for preventing the escape of fluid pressure therefrom. An adaptor may engage with the housing, opening the valve means and allowing the fluid under pressure to enter the adaptor. A removable outer cover may be provided over the access housing once the adaptor is removed for providing additional sealing of the fluid under pressure.

Abstract: In a fuzzy control apparatus in which a rule is capable of being changed during operation, a fuzzy reasoning output which prevails immediately prior to a rule change is stored when a rule change is made, and a fuzzy-control output is generated by combining, after the rule change, the stored fuzzy reasoning output which prevailed immediately prior to the rule change and a fuzzy reasoning output which prevails following the rule change. The ratio of the combination is altered in such a manner that, with the passage of time from the moment at which the rule change is made, there is a gradual decrease in a percentage of the fuzzy reasoning output which prevailed immediately prior to the rule change, and a gradual increase in a percentage of the fuzzy reasoning output which prevails following the rule change, in the fuzzy-control output. Upon passage of a predetermined time from the moment at which the rule change is made, the fuzzy reasoning output which prevails following the rule change is outputted as the fuzzy-control output. As a result, a sudden change in the output at the time of a rule change is prevented so that a smooth changeover can be carried out.

Abstract: An enclosure (12) for electrical equipment (14) includes a fan mounted on an interior surface of the enclosure (12) and adapted to blow air outwardly from the enclosure (12) through a grille (24). The grille (24) includes a plurality of sets (90-96) of short, wide elongated slots, each set (90-96) having its slots disposed perpendicular to a radial direction of the fan hub (44) passing through the slots. The enclosure material between the slot sets (e.g. 90,92) overlies struts (50) forming part of the support for the hub (44) carrying the fan blades. The construction provides low noise from air blown through the slots, while maintaining robust grille construction.

Abstract: A MOSFET switch with a gate formed in a trench has a drain which includes a region of relatively high resistivity adjacent the trench and a region of relatively low resistivity further away from the trench. The drain may also include a "delta" layer having even lower resistivity in a central region of the MOSFET cell. The high resistivity region limits the strength of the electric field at the edge of the trench (particularly where there are any sharp corners) and thereby avoids damage to the gate oxide layer. The central "delta" layer helps to insure that any breakdown will occur near the center of the MOSFET cell, away from the gate oxide, and to lower the resistance of the MOSFET when it is in an on condition.

Abstract: A method for generating postage evidence includes providing addressee information separated into a plurality of address fields. A predetermined section of each address field, appropriate for authentication purposes, is selected to obtain selected address data. An error correction code is generated for the selected address data and a secure hash is generated of the selected address data. The secure hash is sent with postal data, including postage amount and date, to a digital token generation process that generates at least one digital token using the secure hash for evidencing postage. An indicia including the digital token and the postal data is generated and then printed on a mail piece with the error correction code and the addressee information. In a digital token verification process, the addressee information and the error correcting code are read from the mailpiece and the postal data is read from the indicia. An error correction algorithm is used to determine if errors are correctable. If correctable, a predetermined section of each address field is selected to obtain selected address data. A secure hash of the selected address data is generated and sent with the postal data to a digital token verification process.

Abstract: A system which avoids the bandwidth inefficiencies of simply providing multiple separate and independent channels for distributing data services over television compatible networks by considering the multiple channels as one unit and managing them as one unit with an upstream bandwidth management unit. This bandwidth management unit dynamically assigns active users to unused bandwidth among multiple channels. To accomplish this, the bandwidth management unit records each request for channel bandwidth that is made, each request that is being actively fulfilled, and each request that has been completed. Thus, data service providers, such as multimedia services, can efficiently use multiple 6 megahertz television network compatible channels to distribute their data to many requesters/users at high rates of speed over a relatively inexpensive existing network.

The vasoocclusion member may be a small helical coil or braid variously comprising a suitable metal, or, in the case of a braid, such metal may be co-woven with various polymeric or natural fibers. Fibers may be introduced onto the device and affixed to the member. The constituent member may be also be covered with a fibrous braid. The device is typically introduced through a catheter. The device is passed axially through the catheter sheath and assumes its form upon exiting the catheter without further action. The invention also includes methods of winding the anatomically shaped vasoocclusive device into appropriately shaped forms and annealing them to form various devices.

Abstract: A zinc oxide fine particle-adhered composite material consists essentially of a substrate and zinc oxide fine particles adhered thereto. The composite material is characterized in that the zinc oxide fine particles deposited, from an aqueous medium, on the surface of the substrate are firmly adhered to the surface without using any binder and the zinc oxide fine particles are substantially exposed on the surface. The composite material is prepared by, for instance, a method which comprises the step of coming an aqueous suspension of zinc oxide fine particle in contact with a substrate to thus deposit the zinc oxide fine particles on the surface of the substrate. The composite material allows for the zinc oxide particles to sufficiently show their antibacterial, deodorizing, UV absorbing, photocatalytic, stain-proofing and purifying activities without any delay.
