摘要:
A plastics container having oxygen permeability of 3 cc/m.sup.2.day.atm or more is filled with an antiseptic toothpaste composition comprising an aluminum oxide compound such as aluminum oxide trihydrate as a main abrasive and a polyhydric alcohol such as propylene glycol, sorbitol, etc. in an amount of 5 to 100 moles in fluoride-free systems or 4.0 to 100 moles in fluoride-containing systems per liter of water in the toothpaste composition.
摘要:
A semiconductor device is disclosed that is capable of improving the drain breakdown voltage during operation. The semiconductor device includes a first drain region that is arranged to extend from the vicinity of an end portion of the gate electrode at the drain electrode side in a direction toward the drain electrode, a drain contact region that is formed within the first drain region and comes into contact with the drain electrode, and a second drain region that is formed around and underneath the drain contact region. The second drain contact region has an impurity concentration that is higher than the impurity concentration of the first drain contact region and lower than the impurity concentration of the drain contact region. An end portion of the second drain region at the gate electrode side is positioned away from the end portion of the gate electrode by a predetermined distance.
