Filed: 1981-05-04
Abstract: PURPOSE: To protect crops easily and quickly detecting idle machines by indicating the position thereof by light, while sounding an alarm as soon as any one of electric fans for preventing freeze-frost damage stops due to overload or the like.  
     CONSTITUTION: Electricity is separately fed to a plurality of frost preventing  fans 2 (normally, tens in the number) via a distribution line and a branch line from the power source. When a main switch gear is closed to apply voltage to power source terminals 1 of boxes 5 housing overload breakers, an electromagnetic switch gear 7 is closed and an auxiliary contactor 8 is opened with an electromagnetic coil 9 to operate a frost prevening fan 2 and an operation indication lamp 4 comes on. When the frost preventing fans fail to work due to a trouble such as overload, interlayer short-circuiting and single-line disconnection, a switch gear 6b is tripped by an overcurrent sensing section 6a of an overcurrent breaking mechanism 6 to cut the energization of the elelctromagnetic coil 9. Thus, the switch gear 7 is opened and the contactor 8 is closed to stop the frost fans, and inactive indication lamp 3 and an alarm 19 are actuated.

IPC: F24F11/00
Filed: 1984-04-06
Abstract: PURPOSE:To prevent circuit components from being damaged due to a short-circuit current by operating an open-type eddy current preventing apparatus even when a connection cable is connected erroneously. CONSTITUTION:In the case of a power supply line being an equivalent circuit connected to a signal input terminals C' and D', when the short-circuit current begins to flow on a route of cable B-D', resistor 11, photocoupler 8, diode 9, fuse 12, cable C'-A, a potential difference is produced in the resistor 11. Therefore, a triac 10 is triggered and assumes an ON state. The short-circuit current almost bypasses an FLS10. If the fuse 12 is selected to one having a capacity which is less than the short-circuit resistance quantity of the FLS10, the fuse 12 can be cut out without causing break of components. Therefore, in a control circuit system having a plurality of circuit blocks, sufficient protection of the control system can be secured with respect to the erroneous connection of electric wires.

IPC: H04N5/922
Filed: 1978-06-06
Abstract: PURPOSE: To perform emphasis of good phase characteristics by generating preshoot and overshoot through the use of a high frequency emphasis circuit.  
     CONSTITUTION: Waveform delayed by τ time is generated across the matching resistance 4-5 of line 4-5 through the collector of the transistor 4-2 of a high frequency emphasis circuit free from phase distortions provided with the delay line 4-5 and the line 4-5 by the application of video pulse signal. On the other hand, the signal having been amplified by a transistor 4-4 through a resistance 4-3 reflects at the line 4-5 from the resistance 4-6 and the waveform delayed by 2τ time is also generated in the resistance 4-6. These waveforms are combined and preshoot and overshoot are symmertically applied to become the emphasized waveform of flat and good phase characteristics, which is then applied to an FM modulating circuit. The deemphasis after the FM demodulation is also well accomplished in a similar manner in a high frequency reduction circuit.
