Title: Defect inspecting device for optical disk substrate
Inventor: KONO HIDEKAZU
IPC: G11B7/26
Filed: 1985-04-11
Abstract: PURPOSE:To detect defect inside of an optical disk substrate by including a differentiating circuit that differentiate output of a reflected light detector and a transmitted light detector that detects laser light that passed the optical disk substrate and a differentiating circuit that differentiates output of the transmitted light detector. CONSTITUTION:The optical disk substrate 1 is fixed to a holder 2 and mounted on a slidable moving stage 3 and constituted including a detector 4 that detects reflected primary diffracted light, a detector 5 that detects transmitted light and differentiating circuits 6, 7 that differentiate output of respective detector. When a spot of laser light is irradiated on a defective part on the pattern face of the optical disk substrate, change is caused in output of detectors 4, 5, and output of differentiating circuits 6, 7 also changes. When laser light is irradiated on the defect inside of the optical disk substrate, change appears in the intensity of transmitted light. Influence of internal defect does not appear in output of the differentiating circuit 6 that differentiates output of the detector 4. However, pulse corresponding to the kind and size of the defect generates in output of the differentiating circuit 7 that differentiates output of the detector 5 that detects transmitted light. Thereby, defect on the surface of the optical disk substrate and inside defect can be discriminated and defect inside of the optical disk substrate can be detected.

Abstract: PURPOSE:To achieve a higher S/N ratio in an angle beam flaw detection of a small-diameter tube, by setting an oscillation frequency of a probe above a specified frequency in the case of a small-diameter tube to be detected. CONSTITUTION:A part of a tube 2 to be detected is inserted into an immersing tank 1 and conveyed at a specified speed along the length of the axis thereof. Flaw detection probes 3 and 4 which oscillate and receive ultrasonic waves are arranged inside the tank 1 facing each other radially within the coaxial section and flaw detection probes 5 and 6 and 7 and 8 of the same construction are arranged in parallel in such a manner as to adjoin each other axially.

With such an arrangement, when a small-diameter tube with the outer diameter below 30mm undergoes an angle beam flaw detection, an ultrasonic wave is used with the frequency of above 7MHz larger than that generally used. This can decrease a runaround noise overlapped with a received signal.

Title: Electric screen creating device
Inventor: ARAI HIROSHIGE
IPC: A01K63/00
Filed: 1988-03-29
Abstract: PURPOSE:To reduce electrical influences on adjacent facilities, buildings and, etc., by forming an electric screen intercepting what fishes and shellfishes go in and out so as to be arranged in the direction that plural electrode units are cut at a right angle to the intercepting direction for placing the same in the direction that an electrode row with grounding potential is cut at a right angle in cross proximity to each electrode unit. CONSTITUTION:Plural wide electrode units 3 are arranged in the direction almost transverse to an intercepting direction that access of fishes and shellfishes is intercepted, and also are placed in the direction that an electrode row 4 with grounding potential comprising plural electrode bars arranged in cross proximity to each electrode unit 3 is cut at a right angle. And one of two adjacent electrode units 3 is connected to a positive power terminal of a d.c. power supply 5, while the another electrode unit 3 and the electrode row 4 are connected to a negative power terminal of the power supply 5 for grounding. Thus, outside the area that fishes and shellfishes are prevented from entering, the intensity of an electric field gets high in no steps with approach to an entry preventing area, while inside the entry preventing area, the intensity of the electric field abruptly gets low into zero due to the electrode row 4 with the grounding potential. That results in avoiding electrical influences in the preventing area.
