Title: Colored image reproducer with bean/index adjusting system
Inventor: SHIBA TAKASHI
IPC: H04N9/24
Filed: 1984-10-25
Abstract: PURPOSE:To exclude, even when the scan speed of the electric gun deviates from the reference value, any irregularity in the hue of reproduced colors by providing a mean to adjust the timing of the detection of index signals in compliance to the deviation. CONSTITUTION:The index signals from a photoelectric converter 5 undergoes an LC block filter 22. If the frequency of the signals is high, a small value delay time is given, but is it is low, a large value delay time is given to the signals. For the block filter, the loss characteristic and the delay characteristic can not be independently designed each other, and hence, the delay of the demanded time within the index signal band invites a fluctuation (signal ampli tude fluctuation) of a large loss. For this reason, in order to secure the action of circuitry by suppressing the fluctuating part by a limiter amplifier 6, the LC block filter 22 is incircuited before the limiter amplifier 6. In this manner, even when the horizontal linear distortion in the index tube is large, the color reproducibility is made stabe and proper correction of color irregularity is enabled.

Title: Dc power-supply apparatus
Inventor: HOSOYA YUTAKA
IPC: H02M3/28
Filed: 1994-09-19
Abstract: PURPOSE: To obtain a DC power-supply apparatus in which a component mounting space is reduced and whose manufacturing costs are reduced. CONSTITUTION: When an AC power supply 1 is turned on, a thyristor 17 is set to an OFF-state, an inrush current which flows to the output side of a full-wave rectifier circuit 2 flows through a diode 7 for charging and a resistor 16 for current limiting, and the inrush current is limited. In addition, when a load 3 is started, the thyristor 17 is set to an ON-state, and, after that, a charging current which flows to a first capacitor 5 and a second capacitor 6 flows through the thyristor 17. As a result, since a current which flows to the thyristor 17 is small in an ordinary operation after the load 3 has been started, the amount of generated heat can be suppressed, the outward size of a heat-dissipating device or the like can be made small, and a component mounting space can be reduced.  In addition, since it is not required to install an inrush-current limiting circuit separately, the number of components can be reduced, and the manufacturing costs of a DC power-supply apparatus can be reduced.
