Title: Detection of crack position in bed of ground surface
Inventor: KIMURA SHIGEHIKO
IPC: G01V5/00
Filed: 1982-03-31
Abstract: PURPOSE:To determine the presence of cracks in the bed by calculating the ratio of a peak counting rate and a variation rate of the peak ratio for Gamma rays from three nuclides - <40>K, <208>Tl and <214>Bi. CONSTITUTION:Gamma rays from nuclides of <40>K, <208>Tl and <214>Bi are detected with a NaI detector on the surface ground part to measure (areas C, A and B in the drawing) a counting rate (window counting rate) in an energy range giving a photoelectric effect on the highest energy (1.46MeV, 2.61MeV and 1.76MeV for respective nuclides). Counting rates D, E and F due to compton scattering contained in the window counting rates of <214>Bi and <40>K are removed to obtain H and G. When G/A, G/H and H/A are subtracted from respective A, H and G with peak values A-C, each peak ratio will be constant for the surface grounds to cancel variations in the peak counting rates of the nuclides depending on geometric conditions. Thus, when <222>Rh rises from cracks of the bed, the peak ratios A and B increases sharply thereby enabling clear determination on the presence of the cracks.

Filed: 1981-04-09
Abstract: PURPOSE: A cocoon boilder, a thread end groper, an end picker and an end feeder are integrated in a tank to effect the feeding end, as the yarn thickness is automatically controlled, thus reducing the stages of winding process.  
     CONSTITUTION: The yarn-end groper 10 is set above the jacketed tank 2 filled with hot water at the centerm. Thread ends are pulled and collected from cocoons in the tank 2, then passed through the hole 26 of the yarn guide in the end picker 27. The collected threads are passed through the hole 25 that is bored through the support base 24 for the end groper 10, the support for revolving part 13, cum 15 and bevel gear 14 and passed through another yarn guide hole 23 in the vibrating arm 29, threaded on drum wheels 50, 60, 59 to form a kennel. Then, the yarn passes through the traverse mechanism 67 and is wound up around the frame 66. When the yarn-thickness detector 45 detects the lack in thickness of the yarn which is being wound 72, the electromagnetic clutch operates to vibrate the end groper 17 toward the rotation center of the base 24 to effect the end feeding.

Title: Controller for dc motor
Inventor: KUGIOKA MICHIHIRO
IPC: H02P7/288
Filed: 1988-03-09
Abstract: PURPOSE:To maintain the rotating speed of a DC motor constant even if the resistance value of the motor is varied by controlling a current supplied to the motor in response to the variation component of the resistance value of the motor. CONSTITUTION:Resistors RT, RS, R1, R2 are connected in parallel with a DC motor M. Here, the resistance values of the resistors R1, R2 are set to the same value smaller than the resistance value Rm of the internal resistance of the motor M, and so selected that the temperature coefficient of the resistor R1 is equal to that of the internal resistance of the motor. An integrated circuit IC so controls a current Im supplied to the motor M that a voltage between the terminals of the resistor RS becomes a reference voltage Vref. On the other hand, when the resistance value of the resistor R1 becomes large by Joule heat, the output of an error amplifier A2 is increased to increase the collector current of a transistor Q. Thus, the current Im of the motor M is increased.

Abstract: PURPOSE:To obtain a very easy-to-watch image in which the break of block and white is not visually inconspicuous by detecting and compensating the demodulated output when a demodulated output exceeds a prescribed level corresponding to the break. CONSTITUTION:An A/D converter 8 converts an FM demodulated signal to a digital signal S0(k), and when the output of the digital signal S0(k) to be converted exceeds a prescribed level range, it is replaced with a prescribed value to be set in the upper limit value vicinity of a normal demodulating range, and it is outputted. For example, when an unbalanced FM wave, in which an upside wave is suppressed and a downside wave is emphasized due to the passage of a reproducing RF equalizer, is inputted and broken, by utilizing the fact that the output of the demodulated signal exceeds the prescribed level range, the break of the output signal of the demodulated signal is compensated. Thus, the demodulated output is made into a proper range, and the generation of the image to be broken into the black and white can be prevented.
