发明名称 INSPECTION OF HAIR
摘要 PURPOSE:To display the number, width, density, etc. of the cuticle of the hair by touching the surface of the hair with a needle, moving the needle, converting and amplifying the oscillation thereof to electrical pulses, transmitting further the electrical signal via a signal converting circuit to an arithmetic processing circuit to have the same processed by the circuit and measuring the number and distribution of the electrical pulses having the crest value exceeding a specified value. CONSTITUTION:A needle 5 attached to a cantilever 4 is pressed to the hair 3 which is tensed by a clip 2 and is attached to a base 1. A sliding base 8 attached with an oscillation pickup 6 and an amplifier circuit 7 is moved in the longitudinal direction of the hair 3 by means of a motor 9. The needle 5 moves in contact with the surface of the cuticle of the hair and moves vertically particularly where the cuticle of the hair changes. The oscillation is converted to electrical pulses by the pickup 6 and the pulses are passed through an amplifier circuit 7, by which the pulses are made into a waveform. The waveform is shaped to a rectangular wave by waveform shaping circuit 11 having a threshold value (x), by which a series of the rectangular waves are obtd. An arithmetic circuit 12 calculates the number, average density and distribution of the square waves by receiving a series of such rectangular waves and displays the same on a display part 13. These numerical values indicate quantitatively the condition of the surface of the hair such as the number, average width, density, etc. of the cuticle of the hair and therefore these values are translated to such values which are displayed.
