Abstract: PURPOSE:To make it unnecessary to manually set the range of the effective check again even when the width of an object to be checked is changed by providing a gate signal generating means for extracting an effective part of the reflecting light signals obtained through a photodetecting means. CONSTITUTION:A light beam radiated from a scanner 10 draws a locus of a scanning line 12a on the surface of an object 12 to be checked which is being transferred in an X direction. The light beam 11 is reflected at the scanning line 12a and then received by a photoreceptor 13. The light beam 11 is photoelectrically converted by the photoreceptor 13. A part of an electric signal A output from the photoreceptor 13 and which represents the presence of a defect is emphasized through shaping of waveforms by a filter circuit 14. A signal B is divided by a binary circuit 16 to one exceeding a threshold value and one below the threshold value. For example, a defect signal exceeding the threshold value is designated by 1, while a normal signal is indicated with 0. Thereafter, a signal C output from the binary circuit 16 is, along with a signal E from a detecting width gate circuit 34, input to an AND circuit 27. The signal C is output from the circuit 27 as a defect signal F only when the signal E is effective.

Title: Frequency meter
Inventor: SUZUKI NOBUAKI
IPC: G01R23/10
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To identify the frequency of AC power easily at a low cost. SOLUTION: An input adjusting part 2 performs changeover according to the voltage V0 of AC power 1 and the limitation of a current flowing into a frequency meter. A waveform shaping part 3 forms rectangular wave V2 from voltage V1. A pulse generating part 4 generates pulse V3 indicating the front edge timing of the rectangular wave V2. An arithmetic part 5 integrates the pulse V3 and converts it into DC voltage V4. The voltage V4 proportional to the frequency of the voltage V0 is thus obtained. A display part 6 displays the value, according to the current having passed through a current limiting resistance, by an ammeter. Since the current flowing into the ammeter at this time is proportional to the voltage, frequency can be displayed by replacing current graduation with frequency graduation.
