Title: Feedwater-heater drain system
Inventor: ISHIMARU HITOSHI
IPC: F22D1/34
Filed: 1987-09-28
Abstract: PURPOSE: To stabilize and obtain a cooling water amount of a nuclear reactor by providing a water guide tube for connecting an upstream side of a feed water heater drain pouring point of a condensate supply system to a drain pump inlet side, and supplying a cooling water in a power plant. CONSTITUTION: A chilled water pouring tube 16 is removed from an upstream of a pouring point of a condensate tube 15 for pouring a drain in a drain pump 13, and a chilled water is poured in an inlet of the pump 13. Accordingly, a drain temperature of a high pressure feed water heater 10 can be held sufficiently lower than a saturated temperature of an indoor pressure. Further, as a type of the pump 13, a horizontal pump having a small indoor retained water amount is adopted. And, a temperature drop of the pump condensate is accelerated and increased to prevent a cavitation in the inlet of the pump 13 at the time of abrupt drop of a plant load and to perform a stable continuous operation of the pump. Accordingly, a disturbance of a speed control of a main turbine is eliminated.  Thus, no excess flow rate is given to a condensate supply system pump, and a feed water flow rate to a nuclear reactor 1 can be ensured.

Abstract: PURPOSE:To measure temp. by simple constitution and to control other various apparatuses with a temp. change, by providing a magnet and a plurality of superconductors in a state freely relatively movable in a far and near directions and energizing both of them in the sides to which the both mutually approach. CONSTITUTION:Superconductors 3, 4 different in critical temp. are provided in the space of the case 2 mounted to the upper surface of an electromagnet 1 in a freely up and down movable manner and energized so as to be downwardly moved under their own wts. The superconductors 3, 4 in a normally conductive state are brought into contact with switches 6, 7 to close them and the compressor 8 of a freezer is driven through a control apparatus 9. As a result, when the temp. in the freezer falls until the superconductor 3 on a high critical temp. side becomes critical temp., the superconductor 3 floats from the electromagnet 1 by minus effect to open the switch 6. When the superconductor 4 on a low critical temp. side becomes critical temp. similarly, the switch 7 is turned OFF. When the switches 6, 7 are turned OFF, the driving of the compressor 8 is stopped. By this method, the temp. in the freezer can be held at a value between the critical temps. of the superconductors 3, 4.

Title: Data retransmission system
Inventor: ISHIKAWA KOJI
IPC: H04N1/32
Filed: 1985-10-28
Abstract: PURPOSE:To shorten a communication time by substituting scan length information, where errors are detected before retransmission, with retransmitted block information and inhibiting the retransmission request if the number of errors does not exceed a prescribed value though errors whose number exceeds the prescribed value are detected in one retransmitted block information. CONSTITUTION:Block information 4 is received; and if a prescribed number of or more scan length information which are not restored after MH decoding are included, correctness/error discrimination data C is generated and data retransmission is requested to the transmission side. For example, if said prescribed number is defined as one, retransmission is requested because two scan length information L2 and L3 which are not restored are included. Scan length information which are not restored are defined as scan length information L1' and Li' with respect to data retransmitted to the reception side, and only scan length information L2' and L3' corresponding to timings of '1' of correctness/error data are extracted from retransmitted data, and scan length information L2 and L3 are substituted with them. Since the number of scan length information which are not restored is zero in block information 4 obtained in this manner by one retransmission, the retransmission request is unnecessary.

When the personal number is dialed, said number and subscriber information are transmitted to a charging device 5, and charging information is again totaled in the personal number. This processing is completed, an operation is returned to an original call state.
