Characterization of GABA current in rat septal cholinergic neurons in culture and its modulation by
1995
A cylindrical lock with tumbler and driver pins opened or closed by a cylindrical key in which a cylindrical plug is provided with one row or several rows of " phi "-shaped tumbler pins and the lock body is provided with corresponding driver pins of diversified shapes in equivalent rows. When the lock is closed, the driver pins brake the cylindrical plug at the lock body and thus cannot be rotated. In order to open the lock, the cylindrical key bar is inserted in the key hole of the plug. The key bar is formed with grooves of suitable angle. When the cylindrical key bar is rotated in the key hole, the grooves on the key bar will back up the " phi "-shaped tumbler pins to the periphery of the plug while pushing the driver pins from the plug into said lock body to make the plug free from said lock body. The cylindrical key bar with special designed angled grooves will apply pressure to the " phi "-shaped tumbler pins engaging with said plug so as to actuate the lock latch. Outside the plug, lock body and the diversified driver and tumbler pins of said lock, one set of protecting ring and protecting plate is provided to hide the plug within said lock body to make no forcible points therein so as to reduce the possibility of opening by the thief.
