An encryption device includes a first unit that acquires value information denoting a value of information to be encrypted, and a second unit that calculates a strength parameter denoting an encryption strength, based on the value information. It is thus possible to determine the strength parameter reasonably according to the information to be encrypted.

A gas-insulated switchgear includes a sealed vessel filled with an insulating gas, a circuit breaker held in the sealed vessel, and a branch pipe attached to a lower part of the sealed vessel right below the circuit breaker. The branch pipe defines a hand hole for use in inspecting the circuit breaker, provides a place for installing an absorbent container and forms a foreign matter collecting space.

A method of designing a superconductivity employing apparatus includes the steps of causing a magnetism generating disk-shaped floatable portion (4) to face a disk-shaped fixed portion (2) capable of exhibiting superconductivity with a gap (G) therebetween; initializing the fixed portion (2) to reach a superconducting state at a position where the floatable portion (4) is spaced away from the fixed portion (2) to such an extent that its magnetic field does not influence the fixed portion (2); and using properly first, second, and n-th approach characteristics (S1, S2, Sn) when a difference between an n-th approach characteristic (Sn) and the second characteristic (S2) is smaller than a difference between the first and second characteristics (S1, S2), where the first approach characteristic (S1) is a characteristic of a magnetic floating force obtained by allowing the floatable portion (4) to approach the fixed portion (2), the second approach characteristic (S2) is a characteristic of a magnetic floating force obtained by allowing the floatable portion (4) to approach the fixed portion (2) after the floatable portion (4) is allowed to recede from the fixed portion (2) to such an extent that its magnetic field does not influence the fixed portion (2), and the n-th approach characteristic is a characteristic of a magnetic floating force obtained by repeatedly carrying out the operations subsequent to the operation of the second approach characteristic (S2).

A puffer type gas circuit breaker wherein an insulated nozzle made of heat proof resin and a movable arc contact are mounted on a puffer cylinder to perform an open/close operation of the contact. The insulated nozzle is divided into three areas of a downstream area, an area in the vicinity of the throat and an upstream area. The downstream area and the upstream area are made of heat proof resin alone, while the area in the vicinity of the throat is formed of heat proof resin mixed with an inorganic material such as boron nitride. A movable arc contact cover made of heat proof resin having a downstream area and an upstream area is provided between the insulated nozzle and the movable arc contact, and only the downstream area of the contact cover is made of heat proof resin mixed with inorganic material.

An architecture providing a human interface includes a user input device, a studio or workplace receiving an output of the user input device, the studio being capable of storing and sharing information, and a plurality of agents or functional modules connected to supply/receive data from the studio. The agents are connected in parallel and perform processing as distributed and cooperative processing of functions by the user. The agents are independent components having independent functions performing processing on data in the studio to receive and store items of information, respectively, from and to the studio as a shared information medium, the studio being accessible to the user and to the plurality of agents. Each of the plurality of agents can be independently started depending upon a status of the studio.

An interrupting part 2 is arranged in a vessel 1 that is filled with insulating gas to configure a puffer type gas circuit breaker. The interrupting part 2 having, at least, a main contact 3, 6 on each of fixed- and moving-sides, an arcing contact 4, 7 on each of the fixed- and moving-sides, a puffing device, and an insulative nozzle 10. The insulating gas that became high temperature by being puffed into the arcs is discharged through a puffer shaft 11 of tubular shape. The puffer shaft 11 has a pipe member 11a at the distal end of which the arcing contact 7 is installed, and an end member 11b, one end of which is separably connected to the pipe member 11a with a joint 11 and the other end of which is connected to a rod 12 that links to a manipulator side.
摘要:
A metaphor selecting/switching system in an information processor which incorporates metaphor and function groups 3 and 2 independently, selects a matched metaphor/function combination based on similarities between metaphors and functions and lets input and output of information be performed via an input/output device comprises attribute lists 4 and 5 having information on attributes and similarities regarding each metaphor and each function, a similarity calculator device 6 for calculating similarities from the information on the similarity regarding each metaphor and each function, and a control device 7 for controlling the switching of one metaphor to another and the matching of a particular metaphor with a particular function, switching of one metaphor to another being performed by calculating similarities whenever operation is performed via input/output device.Thus, the function or metaphor having the highest similarity is automatically selected as a well-matched metaphor/function combination. This makes it unnecessary for the user to memorize which metaphor corresponds to which function, and so releases the user from the troublesome work. In addition, the user can be presented with information with the metaphor most familiar to him, because the matching of metaphors with functions is achieved in terms of similarities therebetween. Even with an information processor having additional functions, the work load on the user can be reduced, because it can be used with metaphors familiar with him.
