Title: Current controller of power converter
Inventor: MATSUDA TOSHIHIKO
IPC: H02P7/292
Filed: 1984-09-20
Abstract: PURPOSE:To obtain high responsiveness in both current continuous state and current interrupted state by deciding a firing phase angle on the basis of only the result of calculating a current control when a load current is in the current interrupted state. CONSTITUTION:An A/D converter 6 outputs a current momentary value If of a digital signal from the output of a current detector 4 and a current average value If. A delay time circuit 8 outputs an interrupt signal after the prescribed time is elapsed from when a firing pulse generator 7 outputs a firing pulse. When a microcomputer 9 inputs the interrupt signal, it calculates to control the current and the current change rate to decide a firing phase angle alpha. A current interruption detector 11 outputs a current interruption detection signal SD on the basis of the firing pulse and the load current, and when the microcomputer 9 inputs the signal DD, it decides the angle alpha only by the calculation of controlling the current.

Title: Deflecting device
Inventor: KOU YOSHIO
IPC: H01J29/76
Filed: 1981-12-07
Abstract: PURPOSE:To enhance greatly the deflecting efficiency of the captioned device, by forcing a pair of main cores to be magnetically combined by means of an auxiliary core and by making a vertical deflecting coil to be wound around the auxiliary coil in a troidal form with regard to the deflecting device used for a television receiver and the view finder of a video camera. CONSTITUTION:Even if the width in the tube-axial direction of auxiliary cores 6 and 7, namely, vertical defecting coils 8 and 9 is small, a magnetic field space of necessary intensity can be obtained in the tube-axial direction. Consequently, the resistance R can be minimized by shortening the entire length of the winding of coils 8 and 9, so the deflection exponent RI<2> becomes small, and the vertical deflection efficiency can be improved remarkably. On the other hand, with regard to the horizontal deflection, the ineffective magnetic flux can be minimized by bringing main cores 1 and 2 into close contact with a horizontal deflecting coil 5, so the deflection exponent LI<2> becomes small and the efficiency becomes better.
