For the first half of 2012, the operating profit increased by 28.5655 million yuan, an increase of 120.89%. ST Ganhua believed that the main reasons were: 1. On the one hand, the company's headquarters stopped production activities, streamlined the management structure, and greatly reduced personnel; For the legacy of history, there is no need to bear the expenses of retired employees and community management. The management expenses for the current period decreased by RMB 17,917,700. 2. The original factory area of ​​the company's headquarters entered the “three old†transformation procedures, and the financial expenses related to the “three old†transformations were included in the special accounts payable accounting. The financial expenses for the current period decreased by 7,314,700 yuan. 3. The profitability of the biological center has increased, and the paper trade of the company's headquarters has also produced certain benefits.
The net profit attributable to shareholders of listed companies increased by 84.053 million yuan, an increase of 447.48%. The ST share Ganhua believed that the main reason was that the company received 60 million yuan of government subsidies for the current profit and loss.

The main reason was the payment of 174.41 million yuan in employee status conversion and dismissal benefits. 
Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
