Filed: 1993-09-17
Abstract: PURPOSE:To simultaneously measure the volume and dimensions (diameter and depth) of an object to be measured by using an acoustic system by specially providing an acoustic resonance measuring means, resonance frequency measuring means, and arithmetic and control means. CONSTITUTION:Upon receiving a command from a CPU 11, an oscillator 8 oscillates a signal Es (t) and drives a sound source 4 through a sound source amplifier 9. A Helmholtz resonator composed of a sound tube 1 and container 2 resonates upon inputting sounds from the sound source 4 and the acoustic tube 1 becomes resonant with the sounds. The container 2 generates cavity resonance in the depth direction, too. A microphone detects the sound pressure in the resonator and inputs its output signal Em (t) to an FFT analyzer 7. The analyzer 7 calculates a transfer function which uses a signal Es (t) as an input and the signal Em (t) as an output upon receiving a command from a CPU 11. After the calculation, the CPU 11 stops the oscillation of the oscillator 8. The CPU 11 fetches the data of the transfer function, finds each resonance frequency, and stores 12 the resonance frequencies. The CPU 11 finds the, volume, diameter, and depth of the container 2 and outputs the found results to an output device 13.

IPC: G01N27/84
Filed: 1991-08-19
Abstract: PURPOSE:To obtain a dry magnetic particle inspection method simpler than a conventional wet particle inspection method thereby to reduce the inspecting cost without leaving causes for delamination in the case where a coating film is formed afterward. CONSTITUTION:Fluorescent magnetic particles 6 are accommodated in the bottom of a magnetization chamber A where a work 1 is magnetized. The fluorescent particles 6 are dispersed within the magnetization chamber A by spraying air thereto, and adhered to a defect of the magnetized work 1 by the leaking magnetic flux generated at the defect. Then, the work 1 is moved to an inspecting chamber B as a darkroom. When ultraviolet rays are cast to the work, the fluorescent magnetic particles 6 attracted to the defect come to appear and can be inspected by eyes. The work is further transferred to a demagnetization chamber C for demagnetization. Thereafter, the fluorescent magnetic particles 6 adhered to the work 1 are rid of by spraying air from an air nozzle 72 arranged in the periphery of the work 1. Accordingly, a cause for delamination of a coating film in a post-treatment is avoided. The fluorescent magnetic particles 6 are reused.
