Title: Temperature controller
Inventor: UMEDA ARATA
IPC: G05D23/19
Filed: 1982-09-14
Abstract: PURPOSE:To decide easily on whether the temperature of a controlled system attains to a set value and becomes stable or not by using a differentiating circuit, FFs, inverters, display device, etc., to decide on the pulse variation of a power-on rate varying circuit. CONSTITUTION:The output of a differentiating circuit 8 is inputted to the base of a PNP transistor TR12 through an inverter 10 and when a pulse is generated, a capacitor C1 is discharged. The output of a differentiating circuit 9 is inputted to the trigger terminal of an IC13 for a timer through an inverter 11 to put the IC13 in operation. Its output is supplied to the set terminal of an RSFF15 through an iverter 14. Therefore, the FF15 is set by the output of the IC13, and consequently the potential at a terminal Q rises to turn on the LED display device 17 through a driver 16, showing that the temperature of the controlled system attains to the set temperature and becomes stable.

Abstract: PURPOSE:To improve the precision of the detection of a relative speed by measuring a reference frequency difference between both stations by a train approach waring device, etc., and by processing the measurement result at the opposite station. CONSTITUTION:A signal of the reference frequency f1 of a station A is made into pulses through a switch 2, and they are sent from an antenna 3. At a station B, a difference between a signal of f1+DELTAf1 and a signal of the reference frequency f2 of the station B is detected 10 and held 11, by a Doppler shift, and the signal is sent to the station A through a modulator 12, a reference oscillator 9 for the f2, and a switch 8. At the station A, a difference between a signal f2+DELTAf2 having the Doppler shift and the signal f1 is detected 4, and the sum of this difference signal and a signal obtained by modulating the difference signal detected at the station B is calculated 5. Therefore, only a Doppler shift DELTAf1+DELTAf2 appears at an arithmetic output and from this value, the relative speed between the stations A and B is found.
