Abstract: PURPOSE:To facilitate the formation of the test pattern of circuit operation by providing a circuit realizing the transition of state for an undefined state and an addition circuit judging whether the state of a memory element part is in the undefined state. CONSTITUTION:The transition from the initial state of a circuit to an undefined state and the transition connecting all of undefined states in a chain-like manner are performed. An addition circuit a facilitating a test and an addition circuit B having the output terminal of a memory element part (FF) 2 as an input terminal and judging whether the state realized by the FF is an undefined state to send the state realized by the FF to an external output terminal are respectively constituted of inverters 6, 7, AND circuits 8 - 10, 13, 14 and OR circuits 11, 12, 15 as shown by drawings (a), (b). The state variable value of a transition destination state is inputted to the FF to be held thereto in the circuit A but the state variable value is next inputted to the circuit B and, on the basis of the state variable at that time, it is judged whether the state realized by the FF is an undefined state.

IPC: B61B13/00
Filed: 1994-10-03
Abstract: PURPOSE: To carry out transportation with less traveling resistance due to floating by running a fluid in a pipe by way of fluid flowing in an in-pipe fluid body from an elevation direction of a wing, providing magnets respectively facing against each other on the in-pipe fluid body and an out-pipe transport tool and making it move by its interaction through a pipe wall. CONSTITUTION: In-pipe, out-pipe, left and right magnets 5, 4 erase pressure against a pipe wall by mutually attracting each other and leave binding power, that is, driving force in the forwarding direction. In-pipe, out-pipe, upper magnets 7, 6 mutually repel each other, attract each other in the case of making them lower magnets and float an out-pipe transport tool 2 by transmitting buoyancy of an in-pipe fluid body 2' having a wing 3 to the out-pipe transport tool 2 through the pipe wall. Consequently, the out-pipe transport tool 2 moves in accordance with flow of the in-pipe fluid body 2' while floating (hung down in case of lower magnets). Buoyancy of the wing generated by a fluid from the elevation direction is detected by a pressure sensing device, and an angle of elevation of the wing is automatically adjusted by a balancing bar.  It comes to be possible to carry out floating transport by transmitting buoyancy of the wing of the in-pipe fluid body to the out-pipe carrier tool through the magnets and to carry out high speed transport small in traveling resistance.
