Title: Power source device
Inventor: TAKEHARA TAKAO
IPC: G05F1/455
Filed: 1980-09-08
Abstract: PURPOSE:To realize a small-sized, lightweight transformer for power source substantially widening a magnetic flux variation range up to induce the magnetic saturation, by applying a reverse bias previously in resopnse to sudden variations in magnetic flux accompanying with the conduction of a primary current. CONSTITUTION:A voltage induced in the secondary winding 1b of a transformer 1 is outputted through a rectifying circuit 4 and a smoothing circuit 5. The output voltage is fed back to a conduction phase angle control circuit 6 and a triac 2 controls the supply of AC input power. Control windings 1c and 1d, when the triac 2 is on, biase the magnetized state of an iron core 1h previously in the reverse direction. A control current supply circuit 10 supplies conctrol currents to the control windings 1c and 1d and detects the start of primary current supply by detecting that the output of a detection winding 1e has reached a prescribed level. Then, one-shot multivibrators 12 and 13, are operated to supply control currents.

Abstract: PURPOSE: To realize frequency adjustment at high precision and in a wide range by comparing the content of memory circuit controlled externally with the frequency dividing output, and selectively controlling the setting and resetting of the frequency dividers.  
     CONSTITUTION: The output of reference frequency oscillator 1 is divided down by frequency dividers 2 1 , 2 2  ... 2N +1  and is applied to time measuring mechanisms 3 1 , 3 2  ... as well as to integrating circuits 5 1 , 5 2  ... and differentiation circuit 24. A comparator 7 is driven by a reset counter 25. In consequence, the memory contents externally written into nonvolatile memory element 8 or the like according to advance or delay of the time are compared with the frequency-division outputs of frequency dividers 2 1 , 2 2  ... 2N -1 , and a coincidence output of the comparator 7 is passed through a reset circuit 6 to reset the dividers 2 1 , 2 2  ... 2N -1 . At the same time, due to the output signals of the circuit 8, the frequency divider 2N is set or reset according to the advance or delay of the time through a selective circuit 26.

Title: Band pass filter
Inventor: KOMORI KENJI
IPC: H04N5/44
Filed: 1993-04-28
Abstract: PURPOSE:To make the performance of the band pass filter constant by devising the circuit such that a voltage to current conversion means converts an output voltage of a resonance circuit into a current and feeds back the current to the resonance circuit to vary the Q while a resonance frequency f0 is kept constant thereby realizing a phase characteristic of a constant Q regardless of the frequency f0. CONSTITUTION:A gm converter 1 converts an input voltage V1 into a current i1 and the current is injected to an LCR parallel resonance circuit 3 comprising a parallel circuit of a coil Lo, a capacitor Co and a resistor Ro. A gm converter 2 converts an output voltage Vo of the resonance circuit 3 into a current i2 and it is fed back to the resonance circuit 3. Thus, the current fed to the resonance circuit 3 is the sum of the currents i1, i2. Thus, an admittance gm2 of the gm converter 2 is changed to vary the Q while keeping the resonance frequency fo constant without revising components of the resonance circuit 3.
