摘要： Data of a barometric pressure that a barometric pressure sensor outputs, and data of an air volume that an air-volume sensor outputs are input into a system control circuit. The system control circuit is provided with a table storing portion. In the table storing portion, a control table is stored. The control table is formed of a plus supplied-voltage value to fan power set by a barometric pressure value and an air-volume value, and a warning instruction. In a case that the warning instruction is selected based on the barometric pressure value and the air-volume value, the system control circuit turns on a warning-use LED so as to inform a user that a filter is clogged.

摘要： A system control circuit is provided with a table storing portion. In the table storing portion, a table for a positioned-on-a-floor mode and a hung-from-a-ceiling mode, a table for upwardly-positioned, and a table for downwardly-positioned are stored. On each table, temperature of outside air and voltage supplied to each fan power supply are corresponded. In receipt of information indicating a positioned-on-a-floor state (angle=zero degrees) from an attitude detection sensor, the system control circuit selects the table for a positioned-on-a-floor mode and a hung-from-a-ceiling mode. In addition, the system control circuit obtains measured temperature data from a temperature sensor, and applies this measured temperature data to the selection table as a read-out address. As a result, voltage values regarding each fan power supply are read out from the selection table. The system control circuit instructs each fan power supply to drive the fans based on the read-out voltage values.

摘要： Barometric-pressure data that a barometric pressure sensor outputs, and an air volume data that an air-volume sensor outputs are input into a system control circuit. The system control circuit is provided with a table storing portion. In the table storing portion, a control table is stored. The control table defines a voltage value to be added to a fan power supply set by a barometric-pressure value and an air-volume value. The voltage value to be added is voltage added to a normally set voltage value, and is set within a range from 0 (zero) V (volt) to 6 V, for example. The normally set voltage value is voltage set based on temperature detected by a temperature sensor, for example. In this case, the voltage value to be added is applied to voltage that is determined by the outside temperature and applied to the fan power supply.

摘要： A television signal converter includes a CATV tuner having a channel converting function, a gain changing circuit for descrambling the output from the CATV tuner and the like, in order to convert a television signal such as a CATV signal formed by a scrambled video signal into a descrambled television signal of channel 3, for example. The descrambled channel 3 CATV signal outputted from the gain changing circuit includes noise in the reproduced audio signal since the audio carrier is influenced by gain changing. In the present invention, therefore, the audio signal is reproduced from an audio carrier extracted from the front stage of a gain changing circuit. Thus, the reproduced audio signal is released from noise caused by gain changing.

摘要： A delay circuit for delaying an FM video signal is disclosed. The delay circuit includes an input for supplying the FM video signal, an output for producing a delayed FM video signal, and a delay line connected between the input and output for delaying FM video signal. The delay line is defined by a plurality of I.sup.2 Ls connected in cascade. The delay circuit further includes a phase comparator provided for comparing a phase between FM video signal at the input and the delayed FM video signal at the output and for producing a difference signal representing the phase difference. The difference signal is used for changing and injection current to be applied to the I.sup.2 Ls such that the delay effected in the delay line is made substantially equal to the required delay.
