Yuhai Company is engaged to research
and development of piezoelectric products
and related piezoelectric products, the related piezoelectric products includes the piezo sensors and transducer.
The ultrasonic transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive ultrasonic sensor is actually a microphone that can convert ultrasonic signal into electrical signal.

According to the working principle and materials used, the ultrasonic transducer has piezoelectric transducer, electrostatic transducer (capacitive transducer), magnetostrictive transducer, electromagnetic acoustic transducer, mechanical transducer and other types [1].
Japan Media: Global Semiconductor Investment Will Enter Three Strong Times
[Global Tech Correspondent, Wang Huan] According to reports on July 18th by the Japanese newspaper "Nihon Keizai Shimbun," it is anticipated that global sales of semiconductor manufacturing equipment in 2017 will surpass the peak levels seen during the IT bubble of 2000, marking a new record high. This information was disclosed by the U.S.-based semiconductor industry group, the International Semiconductor Equipment and Materials Industry Association (SEMI). South Korea's memory giant, Samsung Electronics, along with other significant investments in equipment, will play a key role in driving this growth. Analyzing by region, the competition is primarily between South Korea and Taiwan. However, in 2018, China's semiconductor investment is expected to reach the scale of South Korea and Taiwan combined, potentially shifting the focus to a "China, South Korea, and Taiwan" dynamic.
Samsung, renowned globally for its advanced semiconductor manufacturing technologies (including its memory factory in Xi'an, China), has been a major player in this sector. On July 11th, SEMI reported that global sales of semiconductor manufacturing equipment would increase by 19.8% year-over-year in 2017, reaching $49.4 billion, surpassing the $47.6 billion mark set in 2000. For 2018, the forecast indicates an additional 8% growth, pushing the figure to $53.2 billion, a milestone as it crosses the $50 billion threshold for the first time.
The primary catalyst for this market expansion is the growing demand for NAND-type flash memory, which serves as essential storage devices for smartphones and data centers. Samsung Electronics invested approximately ¥1 trillion in this area in 2016, with plans to further increase this investment in 2017. Similarly, South Korea's SK Hynix is transitioning its focus toward producing more NAND-type flash memory alongside DRAM.
This shift in memory technology marks a transition into the "3D memory" era, characterized by vertical arrangements and higher capacities, driving the need for upgraded equipment. Analyst Tamura Tetsuya from Nomura Securities noted, "The explosive growth in data demands has led to a critical shortage of memory, with strong market activity likely persisting through the first half of 2018."
The semiconductor industry follows a "silicon cycle," where market conditions oscillate between booms and downturns roughly every 3 to 5 years. Some experts speculate that we've moved beyond these cycles and are now entering a "super cycle" driven by unprecedented demand.
Regionally, South Korea, home to two major memory giants, is projected to see a 70% year-over-year increase in semiconductor investment in 2017, totaling $12.9 billion, placing it at the top of the global investment rankings for the first time. Taiwan, bolstered by the world's largest semiconductor foundry, TSMC, will maintain its semiconductor equipment sales above $10 billion.
Mainland China is also set to become a formidable competitor. By 2018, investment is expected to grow by 60% compared to 2017, reaching $11 billion, surpassing Taiwan to claim the second spot globally. Over the past five years, investment has surged more than threefold since 2013.
Yangtze Memory Technologies, supported by the Ziguang Group established by Tsinghua University, is receiving a $2 trillion yen ($119.78 billion) backing from the Chinese government to construct the world's largest storage facility in Wuhan, Hubei Province. Chairman Zhao Weiguo of Ziguang stated that by 2020, the company aims to rank among the world's top semiconductor firms.
Prior to the 2000s, Japan led semiconductor investments, but today, its share of global investment stands at around 10%. Notable projects include Toshiba's Yokkaichi factory, though its market presence remains relatively weak.
