Title: Detection system for fault of oscillator
Inventor: YOSHII KUNIKATSU
IPC: H03L7/00
Filed: 1979-12-22
Abstract: PURPOSE:To simplify the constitution by detecting faults of oscillators by a common circuit. CONSTITUTION:If oscillator 1 or 2 gets out of phase synchronism, a composite oscillation output has beats shown by (a) in Fig. B. Therefore, the output of diode D1 includes an AC component corresponding to a beat frequency and detection signal C is DC component V2. Signal (d) applied to diode D2 has only the AC component through capacitor C4 and its output (e) is DC component V4. Therefore, if the oscillator gets out of phase synchronism, the DC outputs appear at both output terminals 3 and 4. In case that oscillator 1 or 2 stops oscillation or decreases in output level, the composite output signal becomes low in level as shown by (a) in C in comparison with normal operation.

IPC: B04B7/06
Filed: 1985-07-31
Abstract: PURPOSE:To attain cost reduction by reducing the quantity of oil and to prevent the agitation phenomenon of oil, by providing a float having specific gravity equal to or less than that of lubricant to the upper part of a movable body. CONSTITUTION:A ring shaped float 14 made of duralumin having specific gravity equal to or less than that of lubricant P is arranged to the upper part of a movable body 14 so as to be immersed in the lubricant in such a state that a lower shaft 6 is passed through the central opening of said float 14. In this case, the distance between the outer peripheral surface of the float 14 and the side wall surface of a lubricant tank 1 is made shorter than that between the inner peripheral surface of the float 14 and the lower shaft 6 to prevent the contact of the float 14 with the lower shaft 6. Because the float 14 floats from the movable body 4 by the buoyancy of the lubricant in this arrangement, the oil agitated by the lower shaft 6 is absorbed by the float 14 without losing the damping action of the movable body 4 in the horizontal direction and the deflection turning force imparted to the rotor can be prevented.

Title: Electric field type human body detector
Inventor: TAKADA YUUJI
IPC: G08B13/26
Filed: 1980-11-28
Abstract: PURPOSE:To eliminate the possibility of flase announcing occuring in higher harmonic noises completely by inverting the phase of the output of an oscillator on transmission side at every fixed period with a time division phase inversion circuit thereby obtaining a detection signal. CONSTITUTION:A time division phase inversion circuit 1b inverts the phase of the oscillation output from an oscillator 1a at a fixed period T, and applied the same as a detection signal to an exciting line 2. At this time, the frequency of the beats generated between the detection signal and noises such as higher harmonic noises is apparently 1/2T and therefore it is possible to make the frequency of the beats relatively high by setting the value of the period T beforehand small. Hence, in spite of the case when the beats are contained in the reception signal of a detection line 3, the beats are blocked by a BPF6, and the possibility of causing false announcing is eliminated. The ordinary detection operation of a human body is accomplished by comparing the change level of the voltage induced in the line 3 with a set level in a comparator 7 via an amplifier 4, a detecting circuit 5 and the BPF6 and operating an announcing circuit 8.
