Abstract: PURPOSE:To heat the thermal cathode and an auxiliary electrode while using only a DC power supply for maintaining the required temperatures thereof, by preparing a metal shell having many uniformly made holes or a metal reticular thermal emitter between the thermal cathode and the auxiliary electrode. CONSTITUTION:A thermal emitter 7 having many uniformly made holes is prepared between a thermal cathode 5 and an auxiliary electrode 6. When a tungsten filament 8 is preheated and a DC heating power supply 11 is connected to the filament as shown by a dotted line, the auxilliary electrode 6 is heated by the electrons emitted from the tungsten filament 8. When the temperature of the auxiliary electrode 6 reaches the prescribed value, the DC heating power supply 11 is changed over as shown by a real line. Then, the heat emitter 7 and the thermal cathode 5 are heated by the electrons emitted from the auxiliary electrode 6 so that the auxiliary electrode 6 is maintained at the required temperature in turn due to said radiant heat. In this way, sufficient amount of electrons are supplied into the main discharge room 4 in order to perform arc discharge by using a discharge power supply 12 while heating the thermal cathode 5 and maintaining its temperature.

Abstract: PURPOSE:To enhance the reliability and efficiency of the title device by causing hot water to flow through respective heat transfer pipes in a first evaporator, a second absorber, a first absorber and a first condenser and causing a heat source fluid to flow through a heat transfer pipe in a second evaporator to actuate a heat pump cycle. CONSTITUTION:Hot water which has returned after heat radiation enters a first evaporator 11 and, after its temperature is lowered, it enters a second absorber 42 to be heated. Then, the hot water is sequentially transferred to and heated by a first absorber 12 and a first condenser 14 and is sent to an indoor unit. Heat source water C is transferred to a second evaporator 41 and is discharged after a refrigerant is evaporated. Heat supplied by the second evaporator 41 is used for heating hot water and, thereafter, the heat source water receives heat substantially equal to the heat radiated by the first evaporator 11 from the first absorber 12 and is heated by the first condenser 14. Accordingly, heat in the second evaporator 41 is increased up to a level of the second absorber 42 and is then transferred to the first evaporator 11. Further, heat increased from a level of the first evaporator 11 up to a level of the first absorber 12 is used to heat the hot water and, as a result, a temperature of the hot water is elevated at two stages.

Filed: 1985-07-30
Abstract: PURPOSE:To easily detect an intermusic gap by recording a tape position signal of frequency much lower than that of an information signal to be recorded on an information recording track and other information tracks behind it on plural tracks in a uniform track array. CONSTITUTION:When an intermusic gap signal is recorded, a control signal inputted from a control circuit to an input terminal 27 by key input operation on a keyboard is held at '1' and a recording signal changeover switch 26 is turned on. Then, the tape position signal from a tape position signal generating circuit 28 reaches a recording amplifier 8 through the switch 26 and is amplified and supplied to rotary transformers 13A and 13B, so that it is recorded on a magnetic tape by rotary heads 2A and 2B. This intermusic gap signal is low in frequency, so azimuth loss is small and the signal is reproduced by both of the heads 2A and 2B. Further, the tape position signal is recorded in synchronism with the rotation of a rotary drum to form what is called 'track array', so excellent reproduction is performed even when the rotary heads scan on plural tracks.
