Abstract: A coated antacid comprising sucralfate and an antacid inhibits decline in the adhesion characteristics of sucralfate whereby the drug ingested can reliably show its effect in the stomach. This coated antacid not only shows the mucosa repairing effect of sucralfate itself, but also shows the antacid effect and the gastric mucosa protective effect of the coated antacid, thereby synergistically producing an excellent antiulcer effect and an excellent ulcer inhibiting/healing effect.

Abstract: In a liquid level indicator for an extremely low temperature-liquefied gas wherein a current is caused to flow through a superconductor wire immersed in the extremely low temperature-liquefied gas, a voltage across terminals of the superconductor wire is measured, and the liquid level of the liquefied gas lying between the terminals is gauged on the basis of the measured value, the improvement therein comprising the providing of a current supply portion which, at first, increases the current to be fed to the superconductor wire up to the so-called plateau region in a current - voltage hysteresis curve of the superconductor wire, and thereafter, decreases it down to a return-path rectilinear region in the curve departing from the plateau region, the liquid level being gauged on the basis of the measured value of the terminal voltage of the superconductor wire as obtained by the use of the decreased current.
