Title: Method for diagnosing internal defect of structure surface layer part
Inventor: OI HISASHI
IPC: G01N29/12
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To surely detect the presence/absence, a depth and a size of internal defects at a structure surface layer part, and improve an accuracy for diagnosing ground loose parts and internal defects at deep positions such as inside a concrete body or the like. SOLUTION: An effect by the presence of internal defects such as separation, voids or the like appears to waves after a second cycle in an impact sound signal S1 obtained by applying an impact to a structure surface. Waves of one cycle after an impact time point t1 are a high sound generated primarily from a tile material or the like at the structure surface at a moment of the impact and is a component obstructing the internal defect diagnosis. Therefore, waves of one cycle after the impact time point t1 are masked. An impact sound signal S2 having the waves of one cycle after the impact time point t1 removed is frequency analyzed through Fourier transform. A sharpness, a peak frequency Fp and the like of a power spectrum are obtained.  The presence/absence and a depth of the internal defects are detected from a ratio of the sharpness and a sharpness of a shock sound spectrum of a sound structure surface, and a size of the internal defects is obtained from the peak frequency Fp.

IPC: H04Q9/00
Filed: 1988-08-31
Abstract: PURPOSE:To attain long range transmission by arranging a load impedance connecting between a transmission line and an output transformer decentralizingly to a central controller and housing terminal equipments so as to reduce the waveform distortion of a signal. CONSTITUTION:A load impedance 14a is connected in parallel with the secondary side of an output transformer 12a and a load impedance 14b is connected in parallel with the secondary side of an output transformer 12b and they are connected respectively to a data transmission line 15. Thus, when a central controller 11 and a housing terminal equipment 18 send a signal to the data transmission line 15 by charge/discharge of the output transformers 12a, 12b, the waveform distortion is reduced by the voltage division between the load impedances 14a, 14b and the line resistance of the data transmission line 15. Thus, the long range transmission is attained.

Title: System for measuring outside diameter of work of small diameter
Inventor: TSUDA HIROKATSU
IPC: G01B11/10
Filed: 1992-07-24
Abstract: PURPOSE:To obtain an outside diameter measuring system which can continuously and highly accurately transfer works of small diameters and measure the outside diameters of the works. CONSTITUTION:A pair of right and left steel flat belts 11, 12 are sent in the transfer direction at a predetermined speed. At the same time, a lower part of the outer periphery of a work W is supported from below by inner edges 11a, 12a of the belts. Accordingly, the work W is transferred projecting downward from between the flat belts 11 and 12. During the transfer, the outside diameter of the work W is measured by scanning a laser light L of a laser measuring device 4 at high speeds. The outside diameter of the work in the wide range of approximately 1-10mm can be measured by adjusting the thickness of the flat belts and the distance between the flat belts.

Title: Exciting element for magneto-optical recording
Inventor: TAKEUCHI KOICHI
IPC: G11B11/105
Filed: 1988-08-31
Abstract: PURPOSE:To invert a magnetic field direction at high speed by providing a core for generating a bias magnetic field composed of a main core and an auxiliary core, a coil to excite the core and a conductive member to adhere and surround one surface or above of the surfaces to cross with the main core and the auxiliary core. CONSTITUTION:A laser light to occur from a laser light source 10 is converged to the micro spot of, for example, 1 to 2mum on a magnetizing layer 7 of a disk medium 6 with an objective lens 9, the medium temperature rises, simultaneously, a bias magnetic field is impressed, the inverting magnetic domain is formed at the magnetizing layer 7 and thus, recording is executed. A magnetic field 5b generated from the surface to cross with the recording medium surface of a main core 2 is reduced by an over- current to occur in a conductive member 11 of a high electric conductivity adhered to the main core 2 and auxiliary cores 3a and 3b. This is equivalent to the fact that the magnetic increase at the magnetic field 5b is increased. As the magnetic resistance is increased, the inductance is reduced. Consequently, when the magnetic field 5b is reduced, the inductance is reduced, the rise time of the generated magnetic field when the polarity of the current impressed to a coil 4 is inverted can be shortened and the impressed magnetic field can be switched at high speed.

CONSTITUTION:Light emitted from a light source 9 is reflected by the record disk 4 and enters photodetecting elements 10 and 11 at a detection part 9, but when the optical path is long, namely, when the height H of detection part 3 from the record disk 4 is large (Hl) as shown by a figure (A), the output levels of the photodetecting elements 10 and 11 are generally large. When the optical path is short, namely, when the height H is small (Hs) as shown in a figure (B), the output levels of the photodetecting elements 10 and 11 are large. On the other hand, the 2nd optical sensor 2 provided with a long-sized light shielding plate 13b has the optical path shielded as shown by the figure (B) as the height H decreases and the amount of photodetection by the photodetecting element 11, therefore, decreases. The outputs of the 1st and the 2nd optical sensors 1 and 2 are supplied to an arithmetic processing circuit 14.
