IPC: G01N21/88
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To discriminate kind and degree of a flaw by continuously detecting a patterned flaw and unevenly shaped flaws on a moving steel plate surface on line. SOLUTION: The different polarized light of the reflected light from a steel plate is measured with a linear array camera. A signal process part 12 shading- corrects three species of image signals measured, and so normalizes a normal part as to be central concentration of the entire gradation for flattening, and converts into the light intensity signal indicating relative change to a normal part. The variation polarity and the variation amount of distribution of three species light intensity signals indicating relative change to the normal part are compared with a pattern set in advance, for detecting change of polarized light, and, based on the variation polarity and the variation amount to the normal part, the type of a flaw whose physical properties on the surface is different from a base material is decided.

Title: Stationary auxiliary power supply for vehicle
Inventor: KUMON SEIICHI
IPC: H02M7/48
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To suppress disturbance of input voltage and current by adding the oscillatory component of a filter capacitor to the reference voltage of an inverter thereby controlling the inverter and preventing resonance of an LC filter. SOLUTION: A voltage detected through a voltage sensor 12 is applied to a filter capacitor 3 and passed through a wide band filter 13 in order to extract the oscillatory component which is then added to a reference voltage signal generated from a reference voltage generation circuit 7. Consequently, the output voltage from an inverter 1 fluctuates in synchronism with the fluctuation in the terminal voltage of filter capacitor 3. Since fluctuation in the voltage of filter capacitor 3 is suppressed, resonance of an LC filter is prevented and disturbance of input voltage and current is suppressed.
