Title: Pulse width control current resonance converter
Inventor: ZAITSU TOSHIYUKI
IPC: H02M3/155
Filed: 1989-05-26
Abstract: PURPOSE:To enable variation of switching duty ratio while maintaining the switching period constant by arranging a DC overlapping coil in a resonance coil and varying the inductance according to the degree of overlap. CONSTITUTION:Control circuit 14 for a switching circuit 6 raises the gate voltage of a switching transistor 12 with preset period T and switches the source.drain of the transistor 13 to ON state. Consequently, sinusoidal resonance current flows through a coil 8. A current detector 13 detects zero reset timing of resonance current and pulls down the output voltage from a control circuit 4. A waveform having low duty ratio is obtained under a state where the resonance frequency of resonance circuit is high while a waveform having high duty ratio is obtained under a state where the resonance frequency is low. Output voltage from a smoothing circuit varies according to the value of the duty ratio.

IPC: G06F9/28
Filed: 1978-10-31
Abstract: PURPOSE: To speed up the instruction execution processing by transferring the instruction word read out from the memory storing the instruction word fetched in advance to the microprogram control section directly.  
     CONSTITUTION: For example, during the execution of the instruction 2, the instruction words 3 and 4 to be executed are read out as one word from the main memory and they are transferred via MBU25. The selector switch 24 selects those two instruction words 3 and 4 with section and transfers them to the instruction buffer IB26a. The instruction word 3 written in IB26a is read out in a suitable timing during the execution of the instruction 2 and transferred to the microprogram control section 21 via DBUS27. The control section 21 selects the address information 3-1 linked to the operation code of the instruction word 3 and stores it. When the microstep of the instruction 2 is finished for execution, since the micro instruction 3-1 at the head of the micro routine corresponding to the instruction word 3 to be executed next is executed, the instruction 3 can be executed without providing the microstep at non-operating condition.
