IPC: G01P3/48
Filed: 1977-10-19
Abstract: PURPOSE: To obtain a tachometer of good measurement accuracy by connecting the output terminals of a waveform shaping circuit consisting of a resistance voltage dividing circuit and a constant voltage element thereby removing noise pulses.  
     CONSTITUTION: Input voltage VA is rectified by the rectifying diode D1 of a waveform shaping circuit 1, and its output VA is applied to a zener diode DZ2. At this time, a trigger pulse VB is produced at the output end B of the zener diode. A  monostable multivibrator 2 is triggered by this trigger pulse VB and a one-shot pulse of a constant width is generated. Because of this, the voltage Vc of the base terminal C of the transistor Q3 to which a capacitor C4 is connected falls to a negative potential by the voltage component having been accumulated in the capacitor C4. When the base voltage V c  completely falls, charging is accomplished via volume VR and resistrance R11 to the capacitor C4. Then, one-shot pulse VD is produced on the collector side of a transistor Q4. By driving an ammeter M with this one-shot pulse VD, the number of revolutions may be measured

Filed: 1986-05-30
Abstract: PURPOSE:To secure the proper picture density even with a thin original by using a 1st optical senser having the spectral sensitivity approximately equal to that of an area of a photosensitive body having the maximum spectral sensitivity and a 2nd optical sensor having the spectral sensitivity of a complementary color to the 1st optical sensor.

While an optical sensor 11 serving as the 1st optical sensor has the complementary color relation with the sensor 9 and also has the spectral transmittance characteristics. A yellow original is decided by a DC controller 13 when the output value of the sensor 11 is high and that of the sensor 9 is respectively. While an ordinary original is decided when the output values of both sensors 9 and 11 are set at the same level. Therefore the lamp lighting voltage is fixed at 60V with a yellow or thin original. While the lamp lighting voltage is controlled in response to the CCD output value with other types of originals.
