IPC: F28B11/00
Filed: 1982-11-27
Abstract: PURPOSE:To avoid a shut-off of a plant in a steam generating plant equipped with a side stream type condenser by controlling an amount of steam generation by a failure signal of a system which lowers the condensed water level in the second hot well out of two hot wells of the condenser. CONSTITUTION:In a boiling water type nuclear power plant, the steam generated in a reactor pressure container 1 is directed to a turbin 2 through a main steam pipe 32, and after driving a generator 3 is condensed in a condenser 4, the condensed water being stored in the fist hot well 5. Then, the condensed water is pumped to the second hot well 8 by a side stream pump 6, and is supplied thereafter to the container 1 by a condensed water pump 9 and a water supply pump 11. In this instance, a pump trip detector 71 is provided for detecting a failure in said pump 6 which causes the water level in the second hot well 8 to be lowered. When tripping a pump, one of the water supply pumps 11 is tripped by a control device 70, and a reserve unit is controlled so that it may be started.

IPC: H04Q3/58
Filed: 1985-09-19
Abstract: PURPOSE:To control and save telephone usage rate without taking the circumstances into consideration by making trunk line call regulation automatically and compulsorily. CONSTITUTION:As the relation between usage rate of trunk line telephone and frequency of main wire call is clear, frequency of main wire call can be calculated easily from the limit of telephone rate. Accordingly, the term of telephone rate regulation for each group of users is inputted to a term setting means, and the limit number of times of trunk line call calculated from the limit of telephone rate regulation is inputted to a trunk line call limit setting means 2. On the other hand, objective telephone sets of call regulation at the time of invoking of regulation are classified beforehand and inputted to a regulating means 5, and the content of regulation, for instance, trunk line call from the objective telephone set of call regulation is restricted to local call, is inputted to a regulating means 6. When integration of frequency of trunk line call exceeds the limit of main wire call under above condition, this is detected by a comparing means 4 and a regulation invoking signal is outputted to a telephone regulating means 5 and a content regulating means 6. Accordingly, regulation set by the content regulating means 6 is applied to the telephone set designated by the telephone regulating means 6.

Filed: 1987-08-24
Abstract: PURPOSE:To provide flexibility to a call by forming a zone by a 2nd transmission/reception antenna to a specific location within the radio wave arrival range of a 1st transmission/reception antenna installed in a base station. CONSTITUTION:A telephone set 1 to call a called party is connected to an exchange 2. Plural number, e.g., two base stations 20, 20' are connected to the exchange 2.

Filed: 1989-08-10
Abstract: PURPOSE:To improve the quality of guard monitoring service by starting an alarm display means when an abnormal state is generated during the use of a communication circuit by an external telephone set. CONSTITUTION:When a sensor 50 goes abnormal, a central processing part 40 outputs a transmission request to a transmitting/receiving part 30 to send the sensor abnormality as an alarm, but when a terminal board part 20 recognizes the occupation of a communication line 10 during the continuation of off-hook state of the external telephone set 200, the transmitting/receiving part 30 returns transmission disablement to the central processing part 40. When the central processing part 40 sends a pulse to a menace contact point making part 60, a relay 90 is driven and a menace contact point 80 is made. A rotary lamp/emergency bell part 110 for visibly and audibly displaying an alarm is started by the making of the contact 80. Consequently, the abnormal state is informed to the periphery and the external telephone set 200 can be completely set up to the on-hook state.

Filed: 1993-07-30
Abstract: PURPOSE:To provide an operation control method of an air conditioner capable of comfortable heating, the air conditioner including a refrigerant circulation circuit and a hot water circulation circuit both being of a heat pump type. CONSTITUTION:When room temperature upon starting heating is a temperature or lower where a compressor is turned on, a hot water circulation circuit is turned on together with a refrigerant circulation circuit whereby the refrigerant circulation circuit and the hot water circulation circuit both changed over to heating operation are simultaneously started. Once the room temperature reaches a temperature where the compressor is turned off the refrigerant circulation circuit is turned off and only the hot water circulation circuit is continued in its operation. As the room temperature is further raised to exceed set temperature and reaches a temperature where the hot water circulation circuit is turned off, the hot water circulation circuit is turned off and hence hot air blowoff is interrupted. Further, as the room temperature is lowered to a temperature where the hot water circulation circuit is turned on, only the hot water circulation circuit is turned on to start heating, and further the room temperature is lowered and reaches the temperature where the compressor is turned on, heating operation of the refrigerant circulation circuit is started. For the heating operation the operation of the hot water circulation circuit has priority.

Abstract: PURPOSE:To secure data within a memory cell by controlling not so as to select the word lines more than two among the plural word lines of the same memory cell simultaneously. CONSTITUTION:Outputs 3 and 4 of address decoder circuits 101 and 102 (described as preword lines hereunder) are inputted to a word line selecting control circuit 104. When the preword PW line 3 is one a low level at a changing point 111, a word (W) line 6 changes from the low level to a high level when the PW line 4 changes from the low level to the high level. Next, when the W line 6 is one the high level, a W line 5 changes from the low level to the high level when the PW line 3 changes from the low level to the high level. The W line 6 changes from the high level to the low level simultaneously. When the PW line 3 changes from the high level to the low level at a changing point 114, the W line 5 changes from the high level to the low level. When the W line 6 is in the high level and in a selecting state, the W line 5 changes from the low level to the high level and becomes the selecting state when the PW line 3 changes from the the low level to the high level.The W line 6 changes from the high level to the low level and becomes a non-selecting state simultaneously. Thus, the plural W lines of a same memory cell are not selected simultaneously.
