Setek's cash-for-capital plan, which is expected to invest 125 million of billions of dollars, will gradually gain more than half of the stake and adjust the amount of investment, depending on the company's actual future operational needs. M. Setek is the leading manufacturer of the global solar upstream polycrystalline sil

crystal oscillator" is not accurate. The active crystal oscillator is a complete resonant oscillator. Both the Z crystal oscillator and the Z crystal resonator are electronic devices that provide stable circuit frequencies. The Z crystal oscillator uses the piezoelectric effect of the Z crystal to start vibration, while the Z Crystal Resonator works by the combination of the Z crystal and the built-in IC. The oscillator is directly applied to the cir

Abstract: In order to realize accurate timing of computer software, a high-precision microsecond-level timer is designed. The timer uses the high-precision counter of the computer to complete the timer function. The timer precision on the pentiurn 1 V computer on the Great Wall can reach dozens of microseconds. To test the performance of this high-precision timer, a control program based on Windows multithreading mechanism is developed using Visual C ++, enables the computer to output analog sig

called a piezoelectric resistor abroad. The so-called pressure resistance effect is the effect that the resistivity of semiconductor materials changes with the change of mechanical stress. It can be made into various torque meters, semiconductor microphones, pressure sensors, etc. The main varieties include silicon-sensitive resistors and selenium alloy force-sensitive resistors. Relatively speaking, the alloy resistors have higher sensitivity.Basic

Magnetic Meter : HMC5883L is a method of using the Earth's magnetic field to orient the Arctic, sensing the direction of the planet's magnetic field similar to the Compass's function. MPU6050: Six-axis sensor, integrated 3-axis gyroscope and 3-axis accelerometer, as well as a reserved IIC interface can be connected to the magneto

. Countermeasure: first turn off the power supply. If it sounds strange, open the chassis panel and check it one by one. If it is a bad track, repair or shield it. Be careful with the odor. At this time, you can smell it with your nose, find the component that emits an odor, and then unload it to the computer company for processing. In the middle, you must protect your consumer rights. (If the warranty period is not passed, replace the replacement and repair the repair .) You must never mind thi

The current resolution of this skill is up to 6,300 dots per inch, but the researchers believe it is possible to improve accuracy by making smaller "lines". http://www.dgjdwj.com/tianxingfangzhuanjinju/Three of the rules of success, more ways to goThe thre

Inkjet printer According to working principle can be divided into solid inkjet and liquid inkjet two (now and later more common), and liquid ink-jet mode can be divided into bubbles (canon and HP) and liquid Piezoelectric (Epson). The Bubble technology (bubble jet) is used to heat the nozzle so that ink bubbles are sprayed on the print medium. Where the printer is placed Choose a better placement, you can avoid a lot of unnecessary troub

Reprinted: Http://www.jqr8.com/thread-1403-1-1.html With the increasing intelligence of robots, whether the remote control robot, the interactive robot or the autonomous robot, it is necessary to use the sensor to perceive various parameters of itself and the external environment more and more, and then provide the data reference for the control and decision system to make the appropriate response. From imitating the function of human eyes, ears, nose, and hands, the sensors of vision, hearing,

this is the boot program used to store the hard disk controller. Some hard disks do not use this chip, but have flash memory to store programs in the controller chip. These little things are not chips, but piezoelectric vibration sensors. When a hard disk is hit, they can move the head to a safe place, but it is more likely that it marks a value somewhere, indicating that your warranty is invalid because it is your own hard disk. Here is where the

disadvantage of using liquid crystal materials is that the adjustment speed is slow, while electro-optic crystals generally require an extremely high operating voltage. This type of polarization controller generally has many disadvantages, such as high insertion loss, high cost, and the wide and narrow work caused by the film and microlens. All-optical fiber Solution As shown in Figure 3a, an all-optical fiber polarization controller with the same working principle can solve the problems of hi

communication are common examples of applications.The simplest way is to use a thermistor temperature sensor in the circuit to manipulate a piezoelectric capacitor in the feedback circuit to make the crystal oscillator frequency more stable.A more precise approachFor example, a microcontroller-controlled crystal oscillator (MCXO) uses an embedded controller to process the temperature input based on the desired algorithm and use a digital-to-analog co

ultrasonic motor is a kind of miniature motor developed by using piezoelectric effect, that is, electric energy and mechanical energy interchange, it is interesting that its first commercial application and the most widely used is in the field of autofocus. Almost all camera manufacturers have their own ultrasonic motor technology, and have taken a complex commercial name, and then feel trouble and use three letters as an abbreviation (about good gen

Although the addresses at the top and bottom of the stack are dynamic and each call is different, the size of the stack space opened by the previous function is certain, depending on the internal variable size of the function. That is to say, although each call of EBP and ESP is different, the difference between EBP and ESP is certainly the same in each call, and ESP is not damaged here, we can calculate the value of EBP th

The 3-bit high is controlled by the other 3 I/O bits, the eight sub-buckets are used to save the collected audio signal data and temporary data for digital signal processing. The RF transceiver module uses nRF24L01 to exchange data with the CPU through the SPI interface. The audio signal generator uses commercially available Standard piezoelectric beeps.
