★Reinforced cardboard that overturns common sense★Excellent processability, can be shaped into various forms★By implementing designs tailored to your needs, improvements in logistics processes are possible★

★Revolutionary Reinforced Cardboard "Naviace" that Defies Conventional Wisdom★ - Higher strength than regular cardboard - Superior processability compared to typical reinforced cardboard We will solve various problems according to customer requests. - 2024 Issues - White Logistics - Response to Scope 3 By implementing container module design, downsizing packaging materials, and improving work efficiency, we can address the above issues. Of course, this will also reduce the labor burden on logistics workers, leading to improved employee retention rates. By leveraging the design capabilities developed since the 1950s, we can meet the diverse needs of our customers with the reinforced cardboard "Naviace"! ↓ For more details, please download the PDF below and consider it ↓

With all packaging made of cardboard, we propose to reduce environmental impact and CO2 emissions while increasing productivity! Do you think that SDGs and costs are in conflict with each other?

Many people believe that "eco-friendly products are expensive." In reality, there is a tendency for this to be true. As a result, even when trying to engage in efforts to reduce environmental impact and achieve the SDGs, it can often be difficult to proceed as planned, leaving one unsure of what to do. With our all-cardboard packaging (cardboard pallets, heavy goods packaging, collective packaging, functional packaging), we can offer benefits beyond just the environment, including: - "Reduction of CO2 emissions (achievement of SDGs goals)" - "Increased productivity" - "Improved logistics efficiency" **Examples:** - 90% reduction in CO2 emissions - 30% reduction in logistics costs due to improved transport efficiency - 30% reduction in packaging time due to increased work efficiency - 30% reduction in labor costs due to increased production efficiency *Note: The current packaging materials used may vary by customer, so this cannot be generalized.* **Other Benefits:** - Packaging can be done by anyone (including women and the elderly) - Easier unpacking during recalls or re-inspections - Company logos can be printed, enhancing advertising effectiveness and brand image - If shipping labels are printed, there is no need to apply them separately Since it is completely custom-made, we will design it according to the customer's usage conditions and requirements.

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at TSP Corporation. ~ In the case of TSP ~ Before the introduction, there were challenges such as dealing with the "paper" sent from various locations and the reliance on specific individuals for the tasks. After the introduction, the input and checking of FB data, which used to take 2 to 3 hours, can now be completed in just 5 minutes. Additionally, the mindset of the accounting department, which was previously reliant on manual entry, has changed. [Case Overview] ■ Challenges before introduction - Dealing with "paper" sent from various locations, reliance on specific individuals ■ Key points of introduction - A robust support system for setup and operation - Easy to start from a small scale both financially and functionally *For more details, please refer to the related links or feel free to contact us.

The facility operating the nurse call system has made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
