Title: Discriminating circuit for same program
Inventor: TOMIYASU ATSUSHI
IPC: H03J7/18
Filed: 1981-10-15
Abstract: PURPOSE:To accurately discriminate whether or not programs are the same, even if there is a delay between broadcast stations, by discriminating the identity through the provision of a delay to one detected output of two detected outputs. CONSTITUTION:Electromagnetic waves introduced from an antenna 1 are distributed to receivers 3 and 4 at a distributor 2. The receiver 3 transmits a detected output of the electromagnetic waves selected by the user, while the receiver 4 transmits detected output of stations other than the reception station of the receiver 4 with sequential tuning under the control of a control circuit 9. A switch circuit transmits 5 one detected output of the receivers 3 and 4 to a signal recognition circuit 7 via a delay circuit 6 and the other detected output to the circuit 7 directly, under the control of the control circuit 9. The signal recognition circuit 7 compares two detected outputs and discriminates the identity every time the control circuit 9 changes the delay time of the delay circuit 6 via a programmable frequency division circuit 10.

Title: Fast breeder
Inventor: MATSUZAKI TOSHIYUKI
IPC: G21C1/02
Filed: 1989-06-29
Abstract: PURPOSE:To secure the safeness of vibration by setting up the structure of a cylindrical partition wall so that the frequency of the partition wall is less than 40 times the sloshing frequency of sodium in the partition wall. CONSTITUTION:The fast breeder is constructed so that at the time of generating a vibrating phenomenon (earthquake, etc.), the vibration directly applied to the wall of a furnace containment by oscillatory waves due to the sloshing (frequency fs) of Na in the furnace wall of the furnace containment is softly received so as to be less than 40 times the frequency of Na sloshing by thinning the plate thickness of the partition wall 5 (cylindrical part) to reduce the vibration. In addition, the height of the oscillatory wave can be reduced by lowering the level of the Na liquid in a furnace wall protection structure 16. Since an inert gas (Ar, etc.) layer is formed on the upper space of the Na liquid face in the structure 16, the thermal influence of high temperature Na which may exert influence upon the wall of the furnace containment can be released.
