Title: High-speed searching drum servo circuit
Inventor: SAWAKI MANABU
IPC: G11B15/473
Filed: 1989-04-18
Abstract: PURPOSE:To expand the dynamic range of drum motor driving at the time of high-speed searching by polarity-inverting a calculated servo error component, and injecting it to a servo system. CONSTITUTION:By using a drum rotational frequency Nn sent from a drum rotation detecting means 9, an azimuth arithmetic means 10 calculates a a servo error component ealpha. Further the servo error component is polarity-inverted (-ealpha), and injected to the servo system. Since the calculated servo error compo nent ealpha is equivalent to the servo error component practically generated in the servo system, when it is polarity-inverted (-ealpha) and injected to the servo system, the servo error component based on an azimuth angle practically generat ed in the servo system can be offset and canceled. Consequently the servo error component based on the azimuth angle at the time of the high-speed servo is eliminated in the servo system. Thus the dynamic range of the drum motor driving is not narrowed.

Title: Method for detecting synchronous signal
Inventor: KATOU MISAO
IPC: G11B20/14
Filed: 1982-06-04
Abstract: PURPOSE:To detect a synchronous signal with compact circuit configuration, by detecting the feature of each pattern without executing the coincidence of the pattern in all bits and detecting a synchronous pattern from the detected result. CONSTITUTION:Outputs Q0, Q1, Q2 of continuous three bits in a 4/8 modulation type conversion code are inputted to a pattern coincidence circuit 19 and whether the output of circuit 19 coincides with ''100'' or not can be detected. When counting up ''1'' by the prescribed number in every detection of ''100'', a counter 29 outputs ''1'' to the terminal Q3, and when the outputs are continued by the prescribed number, the output signal of the Q3 is held. When there is no ''100'' in the outputs Q2, Q1, Q0, the Q2 output of ''1'' is inputted to a terminal CE, counting is stopped and the counter 29 is reset. Therefore, the counter 29 can output ''1'' to the terminal Q3 only when the counting is continued by the prescribed number. Namely, the output of the Q3 at the continuous counting of ''100'' by the prescribed number and the output of an AND circuit 28 are inputted and the AND of these inputs is found by an AND circuit 22 to detect the synchronous signal.

Title: Eddy current flaw detector
Inventor: ENDOU TAKASHI
IPC: G01N27/90
Filed: 1978-08-10
Abstract: PURPOSE: To eliminate only the causes for defects, which exert influences over the circumference of a flaw detecting coil, so that the defect existing in a portion can be detected by merely changing only the shape of the coil without using any special high frequency.  
     CONSTITUTION: Coils having a semicircular shape are paired, and one or plural pairs are used. Coils 2a and 2b are made to have semicircular shapes and are arranged to form a circle on an identical plane while having their chords facing each other. An outer shell 1 for fixing the coils 2a and 2b is made of such plastics as have high-wear resistivity. The coils 2a and 2b are built in as one side of a bridge circuit 9. The defect in the wall of a tube to be defected can be discovered through the variation in the eddy current in either defective one of the coils 2a and 2b. The external condition over the whole tube such as the supporting plate of the tube or a heat exchanging pipe generates no signal because the coils 2a and 2b simultaneously generate the variation in the eddy current of the same quantity.
