Category: Inside Circuits Views: 3543 Rank: 0 The circuit provides a windshield wiper delay, dynamic braking and windshield wipers when they reach the rest position. This prevents the blades passing, which could lead them to stop at a point where they interfere with the vision of drivers. With the original wiper switch off, switch turns on the MLS delay circuit and disconnects the wiring SIB from automobiles. When SI is turned off, the original wiring system and controls the delay circuit is bypassed.  Regarding the SI uses the + 12 V to VI of the battery is a voltage doubler which produces + 18 V. This supply higher voltage is needed to ensure reliable turn on Ql through V2 multivibrator. This arrangement provides about +18 V to the gate of Ql, whose source is less than + 12 V drop V DS Ql. Ql stays on for a time determined by the interval between wipes WIPES potentiometervThe is controlled by the pause control when Cldrops below V + 4, U2 lights, turning on Ql and repeat the cycle.

A BF981 dual-gate Fundamental-frequency-crystal-oscillator For frequencies below 20 MHz, a fundamental-frequency crystal can be used and the resonant tank is no longer required. Also, at this lower frequency range the typical MECL 10,000 propagation delay of 2 ns becomes small compared to the period of oscillation, and it becomes necessary to use a... This circuit is often used by amateur radio operations, shortwave listeners, and other operators of shortwave receivers to calibrate the dial pointer. The oscillator operates at a fundamental frequency of 100 kHz, and the harmonics are used to locate points on the shortwave dial, provided that...
