We will exhibit at the 22nd Mechanical Components Technology Exhibition.

Successfully eliminated loosening permanently with our safety bolts and nuts! Cleared JQA high-speed vibration loosening test! Samples will be distributed at the Mechanical Element Technology Exhibition!

The "Yurumanzo (W-V-LOCK)" is a safety bolt and nut that successfully eliminates loosening permanently by adopting a ratchet mechanism between the bolt, nut, and washer, and by incorporating protrusions on the bottom surface of the washer that bite into the workpiece. All five units tested in the vibration loosening comparison test conducted by the Japan Quality Assurance Organization passed without loosening for over 17 minutes. 【Features】 ■ The bolt and washer are connected using a ratchet system, with several protrusions on one side of the seating surface. ■ The protrusions bite into the tightened object in a wedge shape, preventing the washer from rotating and providing a loosening prevention effect for the entire screw. ■ No loosening occurs even under strong vibrations or long-term use. ■ A high safety and durability loosening prevention mechanism for screws. ■ Patent obtained. * For more details, please request documentation or view the PDF data available for download.

【Key Points of This Seminar】 - What is "push-type"? The true nature of common waste in the workplace - Basic principles of pull production and steps for on-site implementation - The concept of "downstream pull" to reduce work-in-progress and inventory - Case studies of companies that have made improvements - Specific methods for establishing a small start 【Target Audience: Improvement leaders and management】 - Those who feel there is too much "overproduction," "bottlenecks," and "wasteful movements" in the workplace - Those struggling with the gap between production planning and actual work - Those looking for ways to sustain improvement activities - Those who want to know practical methods for implementing TPS (Toyota Production System) ~ Visualizing waste to achieve "just enough, when needed" ~ "Is your workplace being 'pushed'?" In the workplace, issues such as "produced but not used" and "work-in-progress overflowing and halting flow" are common. Many of these problems may stem from push-type production, where items are made "just in case" rather than "because they are needed." A chain moves easily when "pulled," but what happens when it is "pushed"? ── This is precisely the difference between push and pull. We will teach you the system of production that "does not overproduce and does not stagnate" based on the concept of "pull production."

**Seminar Points** Improvement means changing standards for the better. There can be no improvement where there are no standards. If there are no standards, start by creating them. Standards are "rules." What to decide are "procedures," "methods," and "timing." This seminar is focused on determining "procedures" and creating "work instruction documents." **"Without standards, there is no improvement" — Learning from Toyota's teachings on documentation in the workplace** The source of Toyota's strength lies in the concepts of "improvement" and "standardization." At the core of this is a culture of making insights and skills visible in the workplace and documenting them. In other words, it is a system of knowledge transfer through documentation. Relying on the experience and intuition of veterans can be a strength in the workplace, but it also carries the risk that quality may change when people change. By ensuring that everyone performs tasks in the same way, we can achieve the same quality products (good products) in the same amount of time. First and foremost, the development of "work instruction documents" is essential. When presenting work instruction documents in video format, it is also a prerequisite that this "foundational document" is well established. *For more details, please download the PDF or contact us.*

The "Team Cohesion and Team Strength Development Seminar" is an online seminar that provides techniques for demonstrating leadership that drives members and achieves results as a team. "Become a Leader Who Unites the Team from an Excellent Player" The cornerstone of the workplace is the leadership class, such as supervisors and team leaders. It is crucial for these individuals, who know the front lines, to demonstrate leadership that drives the work and leads the members. No matter how excellent a player is, if they work alone, they will only ever be as strong as one horsepower. It’s about demonstrating strength as a team! In other words, it’s about moving people… and that requires a deep understanding of others and the ability to respond. I believe that the most important aspects are the perspective and execution needed to involve those around you, align the vectors, and propel the team forward.
