Title: Safety device of open type burner
Inventor: TAKAHASHI MUTSUHIKO
IPC: F23N5/04
Filed: 1987-03-05
Abstract: PURPOSE:To actuate a fire-extinguishing device at the time of oxygen deficiency and stop the operation thereof at the time of no-fuel burning of a wick by providing a thermal deformation element in the vicinity of a top plate at the upper part of a combustion cylinder, providing an interlocking member through an operating frame actuating an automatic aseismatic fire- extinguishing device so as to respond the thermal deformation element, and also providing an engaging part for engaging the interlocking member. CONSTITUTION:When the burner is put into an oxygen deficient state, a combustion reaction in the vicinity of the tip end of a wick 1 is delayed and the reaction temperature is lowered. Therefore, the temperature in the vicinity of a top plate 25 is also lowered. Thereby a bimetal 5 deflects. By this deflecting force an interlocking member 8 is rotated and disconnected from an engaging part 13. An automatic aseismatic fire-extinguishing device operates and extinguishes fire by the force exerted by a spring 10 through an operating frame 9. Further, a no-fuel burning locking knob 18 is provided at the end of the interlocking member 18. If the knob 18 is set in the direction indicated by the arrow along an inclined surface 21 of a no-fuel burning locking guide 19, the interlocking member 8 is pushed through the operating frame 9. Hence, even when the temperature is lowered at the time of no-fuel burning, the automatic aseismatic fire-extinguishing device 7 cannot operate so that a complete no-fuel burning can be performed.

Title: Phase locking oscillator
Inventor: TACHIBANA ICHIROU
IPC: H03L7/16
Filed: 1980-04-16
Abstract: PURPOSE:To obtain a phase locking oscillator which excels in the output frequency purity with no jumping of lock, by inserting an integrator that integrates the DC component between an oscillator and a phase comparator. CONSTITUTION:An integrator 18 that integrates the DC component is connected between a limiter 14 and a voltage control oscillator 13. For the frequency characteristics of the integrator 18, the integrating function is lost when the input frequency exceeds a certain value fc. Accordingly a frequency of N times as high as the reference frequency is obtained in the normal working by giving a control to the oscillator 13. At the same time, N can be varied by controlling the set voltage given from the terminal 16. The speed of drift is generally lower than fc if the oscillation frequency has a drift, and the oscillator 13 is held at the value set previously by the function of the integrator 18 and in response to a slight change of drift.
