    摘要: A secure computer architecture is disclosed which has a central processing unit means (10), zero or more memory means (30), at least one input means (14, 16, 18, 20, 22, 24, 26), at least one output means (14, 16, 18, 20, 22, 24, 26, 50) and bus means (52, 54) to communicate signals between the means which are all untrusted elements, a trusted access monitor device (28), a trusted gateway device (44) located between each of said memory means (30), a further trusted gateway device (32, 34, 36, 38, 40, 42, 46) located between each of said at least one input means and said bus means, and a further trusted gateway device (32, 34, 36, 38, 40, 42, 48) located between each of said at least one output means and said bus means, where the access monitor device controls either the one-way or two-way direction of said signals through a respective gateway device. In one aspect of the invention each memory location is each of said zero or more memory means (30), and each at least one input means and each at least one output means has a respective tag (within 56) which is representative of a security related attribute associated with the data in that memory location or that input or that output means, said trusted access monitor contains tags which are representative of other security attributes of the processes that can be processed by said central processing unit means, whereby when the central processing unit means, whereby when the central processing unit (10) means attempts to perform an access to data in a memory location or an input operation using said input means or an output operation using said output means, said access monitor compares the respective tags and controls either the one-way or two-way direction of said signals through a respective gateway device. The architecture disclosed can be adapted to fit within a device which connects to a peripheral input/output port of an untrusted computer device.

    摘要: A cleaning web 40 for use in electrostatic reproduction equipment including fibres the cross-section of each of which having a peripheral dimension and an area, wherein the ratio of the peripheral dimension and cross-sectional area is greater than the said ratio for a fibre of circular or substantially circular and equal area of cross-section, for instance tri-lobal or multi-lobal fibres. One side of the cleaning web may be substantially impermeable. A cleaning web having one substantially impermeable side may be produced with conventional fibres.

    摘要: A retractable barrier comprises a flexible element (2) which may be withdrawn from or retracted back into a cylindrical body (4). Body (4) houses a helical spring which is twisted as the element (2) is withdrawn. The energy stored in this twist is used to retract the withdrawn element on release. The element (2) which may be reflective and electrified in use is drawn out of the body through a gap (5) which extends along a major part of the axis of the cylindrical body. This provides a gate or in conjunction with other barriers an enclosure.

    摘要: With an object of providing a method of working a connection end portion of deformed bar for reinforcing concrete considerably reducing working expense by enhancing easiness of working by promoting mechanical strength of a connection portion by being able to work the connection portion without destructing a steel skeleton structure of a connection portion between pieces of steel bar, deformed bar worked by the method and a connection structure of deformed bar, the invention provides a method of working a connection end portion of deformed bar for reinforcing concrete featured in comprising a swaging step in which in deformed bar for reinforcing concrete featured in swaging at least a connection end portion at normal temperature and forming a rolled thread portion at an outer peripheral face of the connection end portion of the deformed bar subjected to the swaging step in which at least one connection end portion is swaged at a normal temperature such that a maximum diameter of the connection end portion is equal to or slightly larger than a diameter of a cylindrical body of the deformed bar or slightly smaller than a diameter of the deformed bar depending on a degree of working; and
       a rolling step of forming a thread portion having a diameter substantially equal to a swaging diameter at an outer peripheral face of the connection end portion of the deformed bar which has been subjected to the swaging step.
