Title: Duty factor varying circuit
Inventor: ONISHI MASARU
IPC: H03K5/04
Filed: 1987-03-17
Abstract: PURPOSE:To reduce adjusting number of processes, by performing amplitude limitation with the pinch off voltage of a FET by changing the amplitude of the output signal of a current switching means after supplying the output signal of the current switching means to the FET by clamping and supplying a DC offset voltage. CONSTITUTION:A pulse inputted to the current switching means 1 is converted to the pulse having the amplitude corresponding to the magnitude of an amplitude adjusting voltage, and is inputted to a duty factor varying means 2 using the FET, however, the pulse is clamped and the DC offset voltage is supplied. At this time, when the amplitude of the output pulse of the current switching means 1 is changed, the pulse width with the pinch off voltage of the FET is varied, and based on the above, the drain output of the FET can be obtained as an output whose amplitude is stabilized at a constant level and whose duty factor is changed. Finally, by varying the output amplitude of the current switching means 1 when a constant DC offset voltage is supplied, the output whose duty factor is changed can be obtained. In such a way, it is possible to reduce the adjusting number of processes.

Filed: 1990-03-13
Abstract: PURPOSE:To eliminate malfunction of preset by activating a switch means in the case of a preset of a comparator so as to short-circuit both terminals thereby making a 1st and a 2nd voltage signal to a same level. CONSTITUTION:An analog switch to short-circuit two input terminals of a comparator 6 is provided. Then a capacitor 5 is not yet charged up in the initial state and a level difference between voltages Vin and Vin' is in existence. A high level signal S1 is outputted from this state to activate the analog switch 50 to bring the voltages to a same level. That is, the voltage Vin being 2 inputs to the comparator 6 before and after the preset of the comparator 6 and the voltage Vin, being its LPF output are short-circuited by activating the analog switch 50. Thus, malfunction of preset attended with a difference of two input levels is eliminated.

Abstract: PURPOSE:To improve the efficiency of light utilization by reflecting light which is not incident to a lens as to light emitted from a fluorescent tube through a reflecting mirror, and returning it to a transparent window, and emitting the light from the transparent window again by utilizing the diffused reflection of the fluorescent material. CONSTITUTION:Light projected from the transparent window 8 of the fluorescent tube 6 is split into light incident to the lens 11 and light incident to the reflecting mirror 12.

Abstract: PURPOSE: To enable easy interlocking of both digitized color pyrometer and electric shutter by combining both.  
     CONSTITUTION: Pulse signals PB, PR of two systems are generated from a photoelectric conversion circuit 1. The frequencies of the signals PB, PR correspond respectively to the wavelengths passed through, for example, blue and red filters and change logarithmically. These signals are counted by counters 6, 3 respectively for a fixed time and the difference thereof is detected by the reference pulse PO of a reference pulse generator 9 and the numerical value indicating the value of color temperature is displayed in a display part 14 through a counter 12. Next, the color temperature conversion filter corresponding to this color temperature is substituted with a red color filter, and the pulse signal Pm generating from the conversion circuit 1 at this time is counted by the counter 3 for a fixed time. When it coincides with the count value of the reference signal PO counted by the counter 12, a shutter drive signal PS is generated. In this way, the interlocking of the color pyrometer and shutter may be readily done.
