Title: Magnetic levitation apparatus
Inventor: MIZUTANI WATARU
IPC: B61B13/08
Filed: 1986-12-19
Abstract: PURPOSE:To realize a magnetic levitation without contact without using an external control circuit by providing a ferromagnetic unit and a diamagnetic unit to either of a levitation unit and a means for levitating the levitation unit, and providing a magnet having a pole capable of magnetically saturating the ferromagnetic unit in a saturation range to the other. CONSTITUTION:Since a ferromagnetic unit 3 provided at a levitation unit by the magnetic field of a magnet 1 is attracted to an opposite pole, a levitating force is generated at the levitation unit 4. However, when the unit 3 approaches the pole 2 in some degree, it is magnetically saturated, and even if it approaches nearer, the attracting force is not increased. Then, when a diamagnetic unit 5 is disposed around the unit 3, a repelling force is generated even if the unit 5 is weakened by the magnet 1, it increases as the unit 5 approaches the opposite pole 2, and it cancels the increase of the attracting force of the unit 3 at a predetermined approaching point. Then, when the repelling force of the unit 5 and the attracting force of the unit 3 of magnetically saturated state are balanced, the levitation unit is stably levitated.

Title: Link control method for multi-channel access transmitter
Inventor: SHIGYO MASAHIRO
IPC: H04L12/28
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To obtain the link control system at a low cost for one-way radio communication by adopting the configuration for a multi-channel access only with a transmission function for a caller and only with a reception function for a called party. SOLUTION: A caller side uses only a transmission function and a called party uses only a reception function to attain multi-channel access. In this method, the system is configured to identify and discriminate an ID code or the like so that an identification code is set to single direction data from the transmitter side to the receiver side, and a transmission channel of a transmission unit 1 to which an input device connects is optionally set. Then a receiver side receiver unit 9 sequentially scans a plurality of channels and when the unit 9 recognizes an identification code over a plurality of number of times, a reception channel of multi-channel access reception is locked.  In the case that the unit 9 cannot recognize the identification code over a plurality of number of times in the channel lock state, the reception channel confirmed at present is released and channel scanning is automatically restored.

Filed: 1986-12-22
Abstract: PURPOSE:To discriminate the trouble of a line processing part by giving an identification number to the line processing part, and reading out this identification number from a spare system processing processor. CONSTITUTION:In the case of accessing to an optional line processing part 3n, a spare processing processor 2 makes only a signal 10n for the line processing part 3n into ON among line processing part selecting signals 10a-10n in order to establish a connection between the spare system processing processor 2 and the line processing part 3n. A spare system connection bus 9 is connected to an order reception circuit 5n through a selection circuit 4n. When the order reception circuit 5n decides that the spare system processing processor 2 has transmitted an order to read the contents of an identification circuit 6n, it delivers the contents of the identification circuit 6n to an answer transmission circuit 7n. On the reception of this contents, the answer transmission circuit 7n delivers said contents as an answer to the spare system processing processor 2 through the spare system connection bus 9.

Abstract: PROBLEM TO BE SOLVED: To surely shield neutrons and suppress the temperature rise of an upper shielding body by constituting the upper shielding body of a neutron shielding member formed of divided bodies, and supplying a coolant to the upper shielding body to cool it. SOLUTION: As the neutron shielding member by divided bodies of an upper shielding body 7, a spherical neutron shielding member 20b is used, and a passage pipe 21 extended through a duct 6 from the lower end of the upper shielding body 7 is set as a cooling mechanism. The end of the passage pipe 21 is situated under a coolant level within the duct 6. Thus, the coolant run through an entrance nozzle 4 compresses a sealed gas 3 in the duct 6 and also raises it to a coolant level 11 in rated operation. On the other hand, the coolant is carried into the upper shielding body 7 through the passage pipe 21, and returned to a furnace core through a handling head 8. Namely, since the coolant is carried in the periphery and clearance of the neutron shielding member 20a, the upper shielding body 7 is cooled to suppress the temperature rise.
