Achieving aspherical lenses that are difficult to grind using molds.

This is an aspheric lens produced by embossing, which is difficult to achieve with conventional grinding methods. While spherical lenses with a constant curvature reduce aberrations by increasing the number of lenses, aspheric lenses with varying curvature can achieve the same effect with just one lens. This also contributes to the slimming down of mechanisms.

[Speaker] Hideo Yamamoto, President and CEO of DIVE COMPASS Inc. [Key Message] "Consumers will no longer be at the end of the power system." By reconfiguring the energy landscape starting from the "consumer" rather than viewing renewable energy, electricity retail, PPA, storage batteries, EVs, VPP, and DSF as separate businesses, there is potential to create new energy businesses in Japan. This presentation will not only introduce the latest trends in Europe but will also consider future market changes and business opportunities from the perspective of "what can be commercialized next in the Japanese market." [Presentation Items] 1. Why consider the electricity market from the consumer's perspective now? 2. Five market changes confirmed at FLEXCON 2026 on the front lines of European DSF 3. The current state of the Japanese DSF market seen through comparison with Europe 4. New consumer-centric energy businesses emerging in Japan 5. Who will hold the connection with consumers by 2030? 6. Q&A / Business card exchange

Are you struggling with the fact that even after raising recruitment costs and hourly wages, on-site personnel are not sticking around? The true causes of turnover lie in "fatigue from heavy labor" and "discomfort in the work environment." However, improving the entire facility or fully automating operations involves enormous initial investments and is not realistic. In this seminar, we will reveal three practical solutions to create a "preferred workplace" based on a case study that reduced investment costs by approximately 20% compared to traditional proposals, without relying on expensive renovations or endless wage increases. The key lies in the integrated design of "construction and equipment" and "robotics." By thoroughly eliminating unnecessary capital investments, we can dramatically reduce the burden on the workforce and enhance productivity. As a company that also engages in outsourcing, we will thoroughly explain the "three principles" that support integrated design, using actual improvement cases. This content is a must-see for executives and site managers who want to fundamentally solve labor shortages within their budgets. [Recommended for] - Companies that continue to face turnover and recruitment difficulties despite raising wages and recruitment costs. - Site managers and executives who considered full building air conditioning or complete automation but abandoned the idea due to high costs. - Site managers and executives who want to balance investment restraint and productivity improvement through relocation or renovations.

We will be exhibiting at the "26th Business Fair" hosted by Seibu Shinkin Bank, which will be held on Thursday, October 15, 2026, at the Triangle Plaza in Shinjuku Sumitomo Building! This event is a corporate exhibition and matching event aimed at expanding business opportunities for small and medium-sized enterprises. Over 300 companies and organizations will participate, promoting their excellent technologies and products to one another.
