摘要： A method of detecting a light spot control signal is disclosed in which, when information is reproduced from an optical disk for optically recording information, a signal level obtained at a high-reflectivity portion of the optical disk is taken out of a signal reproduced from the optical disk, and is used as a control signal, which controls a light spot so that it tracks information stored in the optical disk.

摘要： In a light spot control signal generating device, a light spot is irradiated on a recording medium having tracks on which information is recorded. In order to jump the light spot from a track being scanned thereby to an adjacent track, a signal representative of light quantity of reflection or transmission of the light spot and a track error signal are detected. The two signals are used to judge whether the light spot has passed through an edge of the track. The track error signal is also used to detect a signal representative of an instant at which the light spot is present at the middle point between adjacent tracks, and this signal is used as a timing signal for changing the polarity of a control signal applied to a spot light deflector.

摘要： An optical system for recording and reproducing optical information. A line of synchronization pits for tracking and an information recording area are disposed alternately in advance. At the time of recording, a tracking signal is detected from the line of synchronization pits and while tracking in the information recording area by utilizing this signal, the information signal is recorded in the information recording area. Tracking control in tracking in the information recording area is stabilized by holding the tracking signal which is detected from the synchronization signal and by compensating for an electrical phase delay caused by the holding.

摘要： A paper sheet handling apparatus including a plurality of sheet accumulating portions and a sheet conveyor. A pointed separator is mounted on the conveyor for movement into a stack of paper sheets accumulated in one sheet accumulating portion to divide the stack into two parts with a gap formed therebetween. Gripping fingers mounted on the conveyor are moved into gripping engagement with one of the divided parts of the stack and then retracted to transfer the gripped part of the stack onto the conveyor. Holding members on the conveyor are movable into the gap to hold the paper sheets of the other part of the stack. The conveyor is movable to convey the gripped paper sheets to another sheet accumulating portion. The gripping fingers are again moved to transfer the thus conveyed sheets to the other sheet accumulating portion. Sensors are mounted on the conveyor to determine whether or not the paper sheets to be transferred are directly positioned relative to the sheet transferring members of the sheet accumulating portions and, if not correctly positioned, corrective action is effected in response to the determined incorrect positioning.

摘要： A shock absorber comprising a device for detecting the position and velocity of a moving object; a movement mechanism including a movable part, means for detecting the contact between the movable part and the object, and means for detecting the displacement value of the movable part; and a device for controlling the movement mechanism. With information from the position and velocity detecting device, the control device controls the movement mechanism so that the movable part may move on the course of the object and in the same direction as the moving direction thereof at a velocity corresponding to the velocity of the object. Subsequently, with an information from the contact detecting means, it reduces the velocity of the movable part on the basis of a predetermined deceleration pattern when the object has come into contact with the movable part. Further, with an information from the displacement value detecting means, it executes a positioning control so as to stop the movable part at a predetermined position when the displacement value of the movable part has reached a predetermined value.
