Filed: 1986-04-02
Abstract: PURPOSE:To distinguish whether a signal of circuit output is a true signal or a noise by adding an external disturbing signal to a control signal so as to apply the sun to a control input terminal of a voltage controlled oscillator. CONSTITUTION:An oscillation signal of a voltage controlled oscillator 1 and an Ea input signal are compared by a phase comparator 2, a signal in response to the phase difference is obtained, the phase difference signal is used as an EM demodulation signal via an LPF 3 as one input to an adder 4. The oscillated output from the oscillator 5 to generate disturbance being an external disturbance to a phase locked loop is impressed to other input of the adder 4 and the added output of the adder 4 is used as the control input of the voltage controlled oscillator l. on the other hand, a multiplier 6 is provided, which multiplies the demodulated output of the LPF 3 and the disturbing signal of the oscillator 5, and the multiplied output is led as a synchronization detection signal via an LPF 7. The multiplier 6 and the LPF 7 detect whether or not the same signal as the disturbing signal is included in the demodulation signal. Thus, whether a signal at a demodulation output terminal is a true signal or a noise component is distinguished easily.

IPC: G11B7/0045
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent the maldetection of a spurious data reading starting position synchronization signal and the reduction in the through put by reading data from verifying signals for a prescribed period from the start of the recording signals and inhibiting the detection of the synchronization signal which indicates a starting position. SOLUTION: A synchronization detector 260 reads the data, which indicate the reading starting position of the data section contained in inputted recording signals, the starting position synchronization signals are detected and high level synchronization detecting signals are outputted. Moreover, an ANDing is taken by an AND circuit 261 for the output signals of the detector 260 and the output of a flip-flop 243, i.e., SDV signals and is outputted to a synchronization detector 248. The SDV signals are gated till the reading starting position synchronization signal is outputted. Therefore, no maldetection of erroneous data reading starting position synchronization signal is performed in direct verifying signals, and a true data reading starting position synchronization signal is surely detected.  Thus, the verify error generation caused by a maldetection and the reduction in the through put are prevented.

Title: Drying of low temperature liquefied gas tank
Inventor: YOSHIHARA TAKEO
IPC: F17C3/04
Filed: 1982-05-11
Abstract: PURPOSE:To complete the drying operation using a quantity of N2 gas nearly equal to the capacity of a tank to reduce both the processing time and the cost by introducing said N2 gas always toward the bottom of said tank and discharging the moisture in the tank from its roof outward. CONSTITUTION:The pipe 16 of a unit 11 is connected to the valve 12' of a pipe 7', the valve 15' of a nozzle 14' is opened, the unit 11 is operated, and then, the valve 12' is opened. The N2 gas from an N2 cylinder 10 is turned to a hot dry gas of a required temperature in an evaporator 9 and is introduced into the bottom of the inner tank 3 of an LNG tank 2 from a supply port 13' of the pipe 7'. With the increase in the quantity of N2 gas introduced, the floating water vapor moisture in the existing atmosphere is pushed upward by the N2 gas (the piston effect) due to difference in their densities and dispersed into the atmosphere through the nozzle 14'. Since the purging of O2 can be completed in a very short time compared with drying operation, by setting the target set point at, e.g., 6 percent or below and the dew point at -40 deg.C or below, the O2 purging will have been automatically completed when drying operation is over.

Title: Magnetic clutch, reel stand, and intermediate gear
Inventor: HAYASHI TAKAYOSHI
IPC: F16D7/02
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic clutch in which an inexpensive yoke plate can be used. SOLUTION: A yoke plate 26 is attracted to a magnet plate 24 instead of attracting the magnet plate 24 to the yoke plate 26. The thickness of the yoke plate 26 is reduced to 0.19mm or thinner, and the yoke plate 26 is exposed to the outside. Because any force does not act on the yoke plate 26 and thus the yoke plate 26 can be made thin, even if the yoke plate 26 is made of a material small in coercive force and inexpensive in cost, the flux of the magnet plate 24 will leak to a degree that it can be detected by a magnetic sensor 5.
