IPC: H04N5/60
Filed: 1984-11-14
Abstract: PURPOSE:To prevent in advance generation of pop noise due to fluctuation of a bias voltage in an FM detector by detecting the level fluctuation of a power supply voltage at power interruption and application of power so as to switch forcibly the FM detector in the non-operation state. CONSTITUTION:A bias voltage is fed to transistors (TR) Q3, Q4 by Zener diodes ZD1, ZD2 in a bias control circuit 1, and when the power supply is at a steady- state of 12V, the voltage levels VZ1, VZ2 are nearly identical and the TR Q3 is turned off. The level difference between the reference voltages VZ1, VZ2 at fluctuation of power voltage activates the TR Q3. The TR Q3 shuts the bias voltage to the detector 2 at power voltage fluctuation (e.g., voltage drop or power application) to prevent in advance generation of pop noise from the detector.

When the carrier level is decreased, the base input of the TR15 is increased, the output voltage is increased, the current is increased then the gain is increased. The gain is controlled so that the output is made constant in this way.

Further, if a corrected value is equal to or above the maximum value stored in a storage section 100, this maximum value is set in the storage section 3.  The section within which the values stored in the storage section 100 are varied is limited to a specified section.

Filed: 1992-09-09
Abstract: PURPOSE:To enable continuous vapor deposition at a stabilized evaporation rate by replenishing raw materials for vapor deposition in the form of powder and granular materials of specific sizes at the time of continuously depositing a hardly workable material by evaporation on the surface of a material to be treated by using an electron beam. CONSTITUTION:The material 4, such as Cr, Mg or Mn, which is inferior in plastic deformation, and is hardly workable to a wire, plate material, etc., by ordinary drawing or rolling, is put into a vapor deposition chamber 5 and is heated to evaporate by irradiation with the electron beam 3 by an electron gun 2, by which the vapor deposited film of the Cr, etc., is continuously formed on the surface of the material 1, such as metallic material, plastic or paper. The replenishment of the raw materials 4 for vapor deposition reduced in weight by the vapor deposition is executed by extracting <=5wt.% powder, granular or lump materials 6 of <1mm grain diameter from a container by a vibrator 7 and supplying these materials into the evaporation chamber 5. Since the raw materials 4 for vapor deposition are not too fine, the floating of the raw materials 4 for vapor deposition on the molten surface of the raw materials to be evaporated within the evaporation chamber 5 and the covering of the molten surface do not arise. The degradation in the vapor deposition rate by the decrease of the molten surface to be evaporated is prevented and the vapor deposition is executed stably at a high speed.
