Title: Safety device for electrolytic bath
Inventor: NAKAMURA KAZUO
IPC: C25B9/17
Filed: 1979-01-19
Abstract: PURPOSE:To perform electrolysis operation under safe condition at all times by providing a lower small outlet near the bottom of open tank, providing an outlet and a high liquid level detector for maintaining a high liquid level at the upper part, and connecting the open tank with the electrolytic bath by an U-shaped pipe. CONSTITUTION:In electrolysis, when the supply of saline liquid to the open tank 1 is started, the liquid level of the open tank 1 rises to the high liquid level L3 because flow rate from the lower outlet 4 is smaller than the flow rate of supplied liquid, and it flows into the electrolytic bath 2 through the pipe 8 and the concaved pipe 9 from the upper outlet 5. When the high liquid level detector 6 detects the high liquid level L3, the electrolytic bath is electrified. When the liquid level of the open tank 1 is lowered due to anomaly during electrolysis, it is detected by the detector 6, and electrification and liquid supply are stopped. Thus, the liquid level is lowered to L2 but liquid is stagnated in the U-shaped pipe 9 and hydrogen gas above the vapor-liquid interface L1 in the electrolytic bath 2 is sealed with water, so that the inflow of liquid to the open tank 1 is prevented and danger of hydrogen gas leakage can be assuredly prevented.

Filed: 1995-01-18
Abstract: PURPOSE: To expand the tolerance range to the spatial non-uniformity of the magnetic field intensity of an RF pulse by specifying the flip angle of an IR pulse at a time when an image of T1 contrast is reconstituted by applying a 90 deg. RF pulse after the application of an IR pulse to obtain a magnetic resonance signal. CONSTITUTION: A magnetic resonance imaging apparatus is equipped with a gantry 20 equipped with a static magnetic field magnet 1, a gradient magnetic field coil unit 2 and an RF coil 3. An RF pulse peculiar to an IR method (hereinbelow refferred to as an IR pulse) is applied to a magnetizing spin system arranged along a +Z-axis in the presence of a static magnetic field through the RF coil 3. By this method, the magnetizing spin system of a specific slice region is reversed to a -Z-axis. After the elapse of a delay time, a 90 deg. RF pulse is applied to excite the magnetizing spin system of the specific slice region but, at this time, the flip angle of the IR pulse is set to 180 deg.+α. By this constitution, the tolerance range to the non-uniformity of the magnetic field intensity of the IR pulse is expanded to suppress the generation of contrast abnormality.
