Filed: 1987-06-19
Abstract: PURPOSE:To protect a thyrister valve, by outputting a gate signal both forward and backward at the point of time the forward voltage is applied when the conducting period of a thyrister is long and its turn-OFF period is short. CONSTITUTION:A gate signal generator is equipped with an NOR circuit 6, an OFF-delays 7 and 7', an FF 8, an AND circuit 9 and an OR circuit 10. A set circuit is composed of the NOR circuit 6 and the OFF-delay 7, which sets the FF 8 in detecting the fact that the U-phase conducting period is long. With the output of this FF 8, the gate signal to ignite the X-phase is generated to protect a value at the point of time the X-phase forward voltage is applied. After this point of time, simultaneously with both the U-phase and X-phase forward voltage application, the gate signal is generated, waiting for the attenuation of the transient DC current of the valve current. At the point of time the valve can be safely turned OFF, the FF 8 is reset with the reset circuit output.

Title: Production of magneto-optical disk
Inventor: OKADA SEIJI
IPC: G11B11/10
Filed: 1987-06-18
Abstract: PURPOSE:To enable the stable formation of a Tb-SiO2 film of a magneto-optical disk by embedding Tb chips in an SiO2 target and forming the target into the structure in which the chip surface and the SiO2 surface are flush with each other to decrease the fluctuation in the concn. of Tb in the film so that the easy resetting to an initial value is enabled. CONSTITUTION:The Tb chips 7a are embedded into the SiO2 target 6a and the bottom thereof is bonded to a backing plate 8. The backing plate 8 is a plate consisting of copper, etc., and is cooled by the water running under said plate. The composite target is uniformly etched to have the SiO2 target surface 6a and the Tb chip 7a surface on the same plane and, therefore, the exposing area of the Tb chips 7a can be decreased and the oxidation is lessened. Since the Tb chips 7a are directly adhered to the backing plate 8 and is cooled with the water via the backing plate, the oxidation on the surface of the Tb chips 7a is decreased. Only the surfaces of the Tb chips 7a are selectively presputtered if DC sputtering is executed before the film formation even if the surfaces of the Tb chips 7a are oxidized. The clean state of the surfaces is thus restored.
