Title: Nuclear magnetic resonance device
Inventor: YODA KIYOSHI
IPC: A61B10/00
Filed: 1985-04-12
Abstract: PURPOSE:To eliminate the distortion of a resonance image by detecting the ramp of the flat top part of a ramp magnetic field pulse from the frequency spectral shape of a nuclear magnetic resonace signal and controlling the output current waveform of a power source for a ramp magnetic field coil thereby controlling the ramp in the flat top part to a prescribed value or below. CONSTITUTION:A measuring body is disposed in a static magnetic field. A high-frequency magnetic pulse (a) is passed to a high-frequency coil and the ramp magnetic field pulse (b) is passed to the ramp magnetic field coil. The intensity of the ramp magnetic field pulse is adequately selected as shown by (c) to excite the entire spin of the measuring body. A spin echo (d) is observed. The ramp in the flat top part of the ramp magnetic field pulse intensity is detected and the output electric power waveform of the power source for the ramp magnetic field coil for generating the ramp magnetic field is so controlled that the ramp thereof attains the prescribed value or below in accordance with the result of the detection. Since the ramp in the flat top part of the ramp magnetic field is decreased in the above-mentioned manner, the distortion and blur of the unclear magnetic resonance image is eliminated.

Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce applied voltage at starting by making the structure of a discharge container to easily start. SOLUTION: Most of a discharge container 1a is part 1a1 of the length of the first discharge passage, but part thereof is part 1a2 of the length of the second discharge passage shorter than part 1a1 of the length of the first discharge passage. A pair of electrodes 1b1, 1b2 are arranged outside the discharge container 1a across the parts 1a1, 1a2 of the lengths of the first and second discharge passages. Discharge medium is filled in the discharge container 1a to form excimer molecules. Even if relatively lower voltage is applied between a pair of electrodes 1b1, 1b2, dielectric breakdown first occurs in the discharge medium at part 1a2 of the length of the second discharge passage to form a kindler for discharge. Following the kindler for discharge, discharge is expanded throughout the discharge container to light a dielectric barrier discharge lamp.

Title: Defect inspecting device
Inventor: OGINO KENJI
IPC: H04N7/18
Filed: 1986-04-04
Abstract: PURPOSE:To prevent a light defect from being mistaken for a dark defect by providing an auxiliary threshold level inside a threshold level for light defect detection and fixing a threshold level for dark defect detection in a period where the auxiliary threshold value is exceeded. CONSTITUTION:When the level of a video signal is discriminated based on auxiliary threshold levels Va and Vb, comparators 8a and 8b output an inhibition signal INH'H' on condition that the video signal varies in level slightly. Consequently, if the level deviates toward a light or dark defect side, switches in both threshold value generating circuits 2 and 4 are open in the period where the auxiliary threshold value levels Va and Vb are exceeded. Consequently, both the light defect threshold level and dark defect threshold levels do not vary and are held in the last states. Therefore, even if the video signal varies greatly, a dark and a light defect are not misdetected right after the variation.
