IPC: G11B7/09
Filed: 1988-08-03
Abstract: PURPOSE:To measure the moving quantity of a beam from a reference point and to detect the position fluctuation of the beam over a wide range by obtaining difference between position information at a time point, when an effective signal is generated, and arbitrary position information during a period, in which the effective signal exists. CONSTITUTION:When the position of an optical beam or an infrared beam, etc., is detected, at first, the position information are generated to the origin of a detector, for which first-fourth sensing elements are arranged in the shape of a square with a cross inside. When the beam is incident to one of the sensing elements, at least, a first catching signal is generated. When the first catching signal is inputted, the automatic pursuit of the beam is commanded so that respective sensing signal can be made equal. When the respective sensing signals go to be equal, a second catching signal is generated and the effective signal is generated to show that the position information are effective only during the period, in which the catching signal exists. By obtaining the difference between the position information at the time point, when the effective signal is generated, and the arbitrary position information in the period, in which the effective signal exists, the position fluctuation of the beam can be detected over the wide range.

IPC: F16H37/02
Filed: 1984-09-17
Abstract: PURPOSE:To obtain a constant output by suppress the constant torque performance of a continuously variable transmission by supporting a reaction force applied onto the revolution shaft of the continuously variable transmission by a prime mover. CONSTITUTION:When an input shaft 1 is revolved by a prime mover and the revolution of a friction plate 10 is delayed by shifting a friction wheel 9, the revolution of a hollow-shaft gear 15 and the revolution of a hollow-shaft gear 16 are delayed, and the peripheral speed of the hollow-shaft gear 16 becomes close to that of an input-shaft gear 2, and the revolution of an output shaft 5 is delayed. When the revolution of the friction plate is delayed, each peripheral speed of the input-shaft gear 2 and the hollow-shaft gear 16 becomes equal, and also the peripheral speed of planetary gears 3 and 17 is made equal. Therefore, the restraint for a revolution shaft 6 is released, and idly revolves in the output shaft 5, which stops. Since the torque reaction force of the revolution shaft is returned into the motive power through the input shaft 1, the loads for the friction wheel 9 and the friction plate 10 are lightened.
