摘要： There are provided quaternary ammonium compounds of the formula: ##STR1## wherein R.sub.1 and R.sub.2, each independently represents a hydrogen atom, a C.sub.1 to C.sub.8 lower alkyl or alkenyl group, or C.sub.3 to C.sub.8 lower cycloalkyl, cycloalkenyl, aralkyl or aryl group; or R.sub.1 and R.sub.2 combine with each other in combination with the adjacent N and carbon atoms or further with at least one of nitrogen, oxygen and sulfur atoms to represent a 3- to 8- membered heterocyclic ring group: R.sub.3, R.sub.4 and R.sub.5, each independently represents a C.sub.1 to C.sub.8 lower alkyl or alkenyl group, C.sub.3 to C.sub.8 lower cycloalkyl, cycloalkenyl, aralkyl or aryl group; or either two of R.sub.3, R.sub.4 and R.sub.5 combine with each other in combination with the adjacent N and carbon atoms or further with at least one of nitrogen, oxygen and sulfur atoms to represent a 3- or 8-membered heterocyclic ring group, with the remaining being the same as defined in the above; or R.sub.3, R.sub.4 and R.sub.5 combine with one another in combination with the adjacent N to represent a nitrogen-containing bicyclo ring or nitrogen-containing aromatic ring group: n is an integer of 1 to 8; and x.sup.- represents an anion being capable of forming a quaternary ammonium group.The compounds are useful in treatment of ulcer in mammals.

摘要： This invention provides swimming goggles that improve the field of vision, and particularly improve the field of vision while swimming.The eye cup 2 comprises: a contact section that comes in contact with the area surrounding the eye; a peripheral section 6 that is located around that contact section and that, when worn, extends a specified distance forward in the viewing direction; and a forward-viewing section 7 that is arranged such that the bottom is located on the front end section of the bottom of the peripheral section 6, and the top is located on or near the aforementioned contact section. Also, a difficult-viewing section 14 is located at least at the bottom part of the peripheral section 6 below the center position of the forward-viewing section 7 such that it is more difficult to see through than the top portion of the forward-viewing section 7, which makes it possible to improve the field of vision as well as makes it possible to swim without sensing the light refraction.
