Title: Lens driving circuit of optical disk player
Inventor: KUSANO KAZUTOSHI
IPC: G02B7/08
Filed: 1983-06-24
Abstract: PURPOSE:To obtain a lens driving circuit which is free from a lens shift error due to opening a servo loop by preventing the input voltage of a loop filter from being varied due to opening a signal line. CONSTITUTION:A sample/holding part 2 consists of a signal line opening switch SW2, a capacitor C and a buffer. A lens kick pulse is transmitted from an optical disk controller for temporary stop of a player as well as search of music. This kick pulse turns the switch SW2 off and is also applied to a lense drive amplifier 5 via an adder circuit 4. The amplitude of a tracking error signal is sometimes increased when the SW2 is opened since the transmission of said kick pulse has no relation with the disk revolving state. This amplitude value is held at a capacitor C, and therefore a sudden change of input voltage is never given to a loop filter 3 even with opening of the SW2. This avoid a lens shift error generated when a loop is opened by the SW2.

Abstract: PURPOSE:To arrange and integrate arbitrarily on the same substrate FETs for small signals and low noise and for power each having a different demand for the distribution in an active layer, by maximizing the distribution of an impurity density in the vicinity of a hetero-interface between AlGaAs and GaAs. CONSTITUTION:Al0.3Ga0.7As 2 and GaAs 3 are superposed on a half-insulating GaAs substrate 1. With an SiO2 mask 4 provided, Si ions are implanted into the layer 3 and a density peak is placed on an interface between the layers 3 and 2. With another SiO2 mask provided, Si ions are implanted in three stages, and a peak in the deepest part is placed on the interface between the layers 3 and 2, while an implantation energy is decreased sequentially. The mask being removed, covering is made with AlN6 and heat treatment is applied. Since Si is not activated within the layer 2, the density of the layer 3 increases gradually and then decreases sharply on the interface within a small-signal low-noise region, while it is uniform in a part other than a surface part and turns small sharply on the interface within a high-output region. When the film 6 is removed thereafter and FETs are completed. GaAs MESFETs for small signals and low noise and for a high output are integrated on the same substrate.
