Filed: 1984-03-28
Abstract: For the purpose of averting overloads in a telephone exchange system which comprises information-processing sequential logic systems and overload averting circuits, seizures are counted by the counter according to their respective significance or weighting. Different weightings are stored in memory elements to indicate different types of seizures for a subscriber call such as, for example, a call set up over an incoming trunk line, a call completion from a pulse code modulation switching matrix network over a line trunk group to the selected subscriber and the like which produce different degrees of traffic load for a central control unit or a group control unit. The overall traffic load measurement takes the traffic load to be anticipated with each individual seizure into consideration. Particular application as the group control unit is provided because the balancing effect of statistical averaging is substantially eliminated.

CONSTITUTION:In space heating operation, a switch 15a is closed and a switch 15b is  thrown to the left, so that a contact 21a is closed through energization of a relay 21.  Resultantly, a four-way valve coil 20 and contactors 18, 19 for a fan motor and a compressor are energized for starting space-heating operation. Here, if the amount of frost  attached to a heat exchanger on the side of a heat source becomes greater than a predetermined level, a contact 16 for a defrosting thermostat is opened, so that current  supply to the coil 20 and relay 21 is interrupted. Resultantly, the four-way valve is switched and current supply to the contactor 18 is interrupted for stopping operation  of the fan motor and carrying out defrosting operation. When the defrosting operation  is completed and the contact 16 is closed, the contact 21a is closed through energization of the relay 21 and the fan motor is set into operation. At the same time, current  is supplied to a timer 25, and after passing of a predetermined time, a contact 25a is  closed for supplying current to the coil 20 and thereby switching operation of the apparatus to space-heating operation.

Filed: 1982-04-07
Abstract: PURPOSE:To erase the desired raster with a simple means, by inserting previously a blanking circuit to the output stage of an amplifying circuit of a color signal and controlling the transistor of the blanking circuit with an external switch. CONSTITUTION:A minor blue signal applied to an input terminal 1 is amplified by transistors TRQ4 and Q5, and the DC component of the blue signal is reproduced by a pulse clamping circuit consisting of TRQ6, Q7 and Q8. Then this signal is amplified to a major signal by TRQ9 and Q10 and supplied to a cathode of the blue electronic gun of a CRT. When the blue raster is erased, a raster erasing switch S7 connected to the base of a TRQ11 is turned off. In this case, the bias of the TRQ11 is previously set so that the blanking TRQ11 is always turned on regardless of a blanking signal 6. Therefore the base of the TRQ10 is set at OV, and the TRQ10 is turned off and change the cathode potential toward the direction where the blue electronic gun is cut off. The same circuit is provided also for the red and green rasters respectively.
