In the current market, the quartz wall clock is divided into noisy and no-time functions. Although there are differences, the structure of the internal movement is similar. I wonder if you have encountered the situation that the wall clock is slower? Next, Xiaobian will tell you how to solve the problem that the quartz wall clock is slow.
What should I do if the quartz wall clock is slow? When the quartz wall clock is slow, reduce the capacitance of the quartz wall clock. Quartz wall clocks are slow to adjust. It is very troublesome. The quality of quartz has changed. Or change it. Now it is very cheap. The ordinary quartz wall clock will not change more than 5 yuan in the market.
The working process of the quartz wall clock: after the power is turned on, the integrated circuit and its peripheral quartz crystal oscillator, adjusting the capacitance, etc. generate a standard 4194304 Hz or 32768 Hz oscillating signal, which is processed by the internal frequency dividing circuit and the narrow pulse forming circuit, and then passed through the driving circuit. The pulse signal is applied to the stepping motor. The stepping motor is driven by the second pulse, and the magnetic field generated by the stator coil changes with the alternating pulse. The rotor rotates at a step angle of 180° per second, thereby driving the transmission gear. The entire mechanical train and hands operate to show time. After the alarm function is set, the integrated circuit outputs an audio signal to the sounding device when the operation reaches the set time, and an alarm signal is generated.
The above article is about how to do the quartz wall clock slow and how to do the work process. See here, everyone understands, I hope to help everyone.
Lip gloss:
1. Lip gloss can moisturize lips.
2. Lip gloss can play the role of decorating lips, making people look more colorful.
The difference between lip gloss and Lipstick:
1. The effect of lip gloss is more distinct and unique. Lipstick is low-key, generally used to moisturize lips, and its color is lighter.
2. The color of lip gloss is brighter and more changeable than that of traditional lipstick, but its durability is not as good as that of lipstick.
3. Lip gloss is rich in various highly moisturizing oils and glittering factors, which is bright, transparent, light and moisturized, and makes lips moist and three-dimensional after coloring. Lipstick has high color saturation and strong color hiding power. It is generally used to modify lip shape and color.
