Title: Information recording and reproducing device
Inventor: SHIRAGAMI KAZUHARU
IPC: G11B21/10
Filed: 1986-04-16
Abstract: PURPOSE:To always attain stable tracking control by providing an off-track detection means detecting that a light beam is deviated from a track on a recording medium. CONSTITUTION:If dust or dirt exists on a disk or an external vibration or shock is exerted to the device with a RAM 15 in the storage state, the tracking control is disturbed and a large off-track signal is generated in a differential amplifier circuit 10. The off-track signal is inputted to a comparator 40, which outputs a lowlevel signal when the inputted off-track signal (Vi) has a prescribed value or over. Since an information processing control circuit 32 stores a signal of the tracking control system in the RAM 15 again, the circuit 32 outputs a low/high level pulse signal (line MST) to a pulse generating circuit 29. Thus, the always stable and highly accurate tracking control is attained.

Abstract: PURPOSE: To make only a new key usable by inserting the new key after rotating a rotor to a certain line by insertion of the previous key into a lock, and then rotating the rotor to its original position. CONSTITUTION: Seven bottomed pin holes, for example, are bored at predetermined intervals in a fixed element 2 in a casing 1, and drive pins 4A to 4G are enclosed in the holes, together with a coil spring 5. Also, seven through pin holes that can communicate with the bottomed pin holes via a rotating surface 13 are bored in the large-diameter part of a rotor 3 and code pins 6A to 6G of a predetermined length are inserted into the through pin holes. The small-diameter part of one drive pin 4C is made narrow to such an extent that it can be folded and separated.  To change the key of a tumbler lock, the key to be changed is inserted into a slot in the lock and turned, and, when another key is inserted and turned with the rotor being rotated to a certain line, the end of the specific drive pin advances into the through pin hole, and the small-diameter part between the main body and the end of the pin is located on the rotating surface, so the small-diameter part is folded during rotation and the pin end separates and moves to the adjacent pin hole. The key that can unlock is thus changed.
