Then, the cylinder 11 is put in shortening operation to lower the weight 7, which rolls downward in the hole as cast 2. When the hole as cast 2 is formed as set at this time, the weight 7 passes through the hole as cast 2 while drawing the tension body 6 with specific tension, and consequently an actuator 10a moves down to turn off the detector 10. When a burr is formed in the hole as cast 2, on the other hand, the weight 7 is prevented from passing and the tension of the tension body 6 is eliminated. Then the actuator 10a moves up to turn on the detector 10 and a buzzer 12 sounds to indicate a defective.

Title: Highly water repellent mirror
Inventor: NAKAHIGASHI TAKAHIRO
IPC: C23C16/27
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To drop a waterdrop at once without sticking to a carbon film forming surface even if a waterdrop contacts with the carbon film forming surface, or even if dew condensation is generated on the carbon film forming surface and grows into a waterdrop, by forming a water repellent carbon film on a mirror surface. SOLUTION: A light reflecting surface Sr is formed on the reverse surface of a mirror base body S being a transparent glass plate, and a water repellent carbon film M is formed on an outside surface on the opposite side of the light reflecting surface Sr of its mirror base body S. Therefore, even if a waterdrop contacts with a surface of a carbon film M, or even if dew condensation is generated on the carbon film M and grows into a waterdrop, the waterdrop can drop at once without sticking to it. Since the carbon film M does not easily separate from a mirror main body A, this highly water repellent mirror can maintain its water repellency over a long period of time, and since it can be inexpensively manufactured, water repellency can be improved without requiring running cost.
