• 3D measuring device

High-speed area scanning unaffected by vibrations. For online, offline, quality control, and wafer inspection applications.

The "Flying Spot Scanner" is an optical measuring device that can perform wide-area scans (up to φ80) using XY2-axis galvanometer mirrors. Since stage scanning is not required, there is no influence from vibrations of the stage. Thanks to the principle of spectral interference, it can measure thickness, dimensional shapes, and inspect surface defects. Additionally, because the incident and reflected light are in a coaxial optical system, good results can be obtained even on glossy surfaces. 【Features】 ■ Wide-area scanning ~φ80mm ■ High resolution XY 6.5μm~, Z 1nm~ Minimum beam spot diameter 13μm, high Z resolution due to spectral interference method ■ No XY stage required, no stage vibrations Area scanning using galvanometer mirrors ■ Reduced development costs and shortened development lead times Software development kit (DLL, etc.) available for device integration ■ Applications Thickness measurement of glass substrates for FPD and LCD, measurement of wafer warp (distortion), lens shape inspection, PCB board shape inspection, height measurement of small precision parts, etc. *For more details, please refer to the materials.

[Instructor] Paulstar Communications Inc. Representative Director Koji Kita [Key Lecture Content] Have you ever felt that, despite entrusting work to Generation Z and young employees, they "don't seem to get started," "don't lead to the expected results," or "it's ultimately faster to do it myself"? Behind these situations are various factors, including the recognition gap between supervisors and young employees regarding "entrusting and being entrusted," how to communicate the purpose of the work, the approach, and the scope of discretion, as well as how to follow up after delegating tasks. In this seminar, we will practically explain "how to delegate work" to elicit proactive behavior, taking into account the perspectives and behavioral characteristics of Generation Z and young employees. We will share specific management techniques to help supervisors break free from the burden of work, encourage the autonomy and growth of young employees, and steadily lead to results.

[Speaker] Yoichiro Okuyama, Senior Researcher, Research Department, Hamagin Research Institute, Inc. [Key Lecture Content] In China, the operation of autonomous taxis began in 2021, and now fully unmanned robo-taxis are running in cities like Beijing and Shenzhen. Experiencing a ride reveals the evolution of technology through natural acceleration, smooth steering, and seamless deceleration. Currently, there are several thousand vehicles in operation, but projections suggest that by 2030, this number could exceed one million, accounting for 70% of the global total. What are the underlying factors driving the social implementation of robo-taxis in China? By incorporating local test ride experiences, we will analyze the revenue situation of robo-taxi operating companies and the outlook for market expansion based on data, exploring their future potential. [Lecture Items] 1. Personal experiences of test riding robo-taxis in China 2. Trends in the market size of robo-taxis in China and globally 3. Background of the advancing social implementation of robo-taxis in China 4. Public acceptance and actual usage 5. Performance and challenges of major robo-taxi companies 6. Will robo-taxis become widespread in Japan as well? 7. Q&A / Business card exchange
