Title: Active element
Inventor: SHIMADA SHINJI
IPC: G02F1/135
Filed: 1993-09-14
Abstract: PURPOSE:To obtain an active element having such a structure that a ferroelectric active layer is interposed between two electrodes and having high reliability in which peeling between the electrode and the active layer is suppressed. CONSTITUTION:The active layer 3 consists of two layers of ferroelectric films 4, 5. The one ferroelectric film consists of a material having higher conductivity than the other ferroelectric film. By this constitution, an electric field applied to the film having hither conductivity is decreased so that polarization inversion in this layer is prevented. Thereby, generation of strain between the electrode and the active layer 3 during operation of the element is suppressed.

The inclination of the glass window 7 and the inclination from an angle which is in parallel with the emitting end surface of the chip are set as follows. When the inclination from an angle which is in parallel with the emitting end surface of the chip 1 is made to be, e.g., 20-45 degrees, noise is suppressed, and the noise is excellently eliminated.

Title: Automatic tracking device
Inventor: KOJIMA TETSUO
IPC: G11B5/588
Filed: 1988-09-14
Abstract: PURPOSE:To always execute automatic tracking in a suitable range for a tape recorded in a different condition by switching an amplifier gain when an envelope outside the prescribed range is detected during the automatic tracking. CONSTITUTION:The output of an envelope detecting circuit 11 inputted through an envelope range comparing circuit 14 to a tracking shift circuit 12. When a voltage in a lower range than the prescribed value continues for >= a prescribed period, the circuit 14 sends an amplifier gain output signal (e) to an amplifying circuit 13, increases the gain, and simultaneously sends a restart signal (d) to the circuit 12. When the high voltage continues, the gain is decreased, and the restart signal (d) is sent to the circuit. On the other hand, when the voltage in the prescribed range continues, the output of the amplifier 13 is sent as an envelope signal (c) as it is. Thus, the automatic tracking can be executed for the tape recorded in the different condition.
