Abstract: PROBLEM TO BE SOLVED: To inspect surface defects on the sides of tops of plural rivet-shaped parts at once, by irradiating the sides of tops of the barts which are inserted into through holes in translucent pallet using light from down side of the pallet, and by photographing the reflected light. SOLUTION: A light-shielding cylinder 6 is attached to a lens 2 fixed to a camera 3 to eliminate effect from disturbance light, and a pallet 1 made of translucent material is shined by a surface lighting halogen lamp 5 on its down side. The light radiates the side of top parts of the rivet-shaped parts which are inserted into through holes in the pallet 1, and a camera 3 photograph its reflected light. An image processing device 4 processes the photographed image, and judges whether surface detects are on the side of top parts. By arranging the through holes with same intervals, orderly inserting the components, and radiating light them from downside, light which scatters in a pallet 1 irradiates the side of top of each part circumferencially and uniformly and causes surface defects to generate their shadows.  Thus, surface defects on the sides of tops of plural rivet-shaped barts are inspected at once.

Inventor: MAKI HIDEHIKO
IPC: G11B5/84
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To obtain a structured magnetic recording card of which illegal production is difficult. SOLUTION: A structured magnetic recording card 10 is provided with a structured pattern track St forming a structured pattern expressing ciphered fixed information F (Ki) obtained by ciphering non-rewritable fixed information Ki by a ciphering method F and a magnetic recording track Mt for magnetically recording ciphered variable information E (Ki, V) obtained by ciphering variable information V by a ciphering method E by using the fixed information Ki as a key. Since the fixed information Ki is written as a ciphered information without directly writing it, a preparing rule for the fixed information Ki can not be easily estimated. Since the fixed information Ki to be a ciphering key for variable information V is ciphered, the ciphering method of the variable information V can not be easily deciphered.  Consequently the illegal production of the structured magnetic recording card can be made difficult.

Abstract: PURPOSE:To cancel interference of excited light and reflected light, and reduce noise, by providing 1/4 wavelength plate on a laser optical path, and orthogonally intersecting the polarizig direction of reflected laser beam and the polarizing direction of excited laser beam. CONSTITUTION:A 1/4 wavelength plate 21 is provided on the laser optical path between a semiconductor laser 1 and a recording medium 5 to support a lens barrel 22 which bears a photo detector 9. A moving device 23 which is intended to move the lens barrel 22 in synchronism with the rotation of the recording medium 5 is disposed. A laser beam 2 from the laser 1 runs through a collimator lens 3, the wavelength plate 21, and a condenser lens 4 to become a light spot of a specified size, which is radiated on a track 6. The reflected light containing information due to pits 7 in the track is caused to re-enter the laser 1 in the reverse way of the radiation. Since this reflected light passes through the 1/4 wavelength plate 21 twice, it is 90 deg. different from the polarizing direction at the time of leaving the laser 1. Thus, the signal to noise ratio of the information detection signals may be greatly enhanced.
