Pulsation-reducing liquid pump, a diaphragm liquid pump that significantly reduces pulsation generated during pump suction and discharge.

We have reviewed the design of the pump itself as a liquid pump for pulsation reduction measures. Traditionally, pulsation reduction was achieved using dampers, but we have significantly suppressed pulsation with the pump itself. - FP70 Series We have integrated the pulsation reduction damper with the pump. - FP150 / FP400 / FK1100 Series We have increased the number of diaphragms to a maximum of five, allowing for the cancellation of pulsation within the pump. - FP1.150 / FP1.400 / FK1.1100 Series We have increased the number of diaphragms to a maximum of five, allowing for the cancellation of pulsation within the pump. Additionally, we have improved the maximum allowable discharge pressure to 6 bar (0.6 MPa), achieving smooth liquid transfer even under challenging pressure conditions.

● The production time for casting prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly creating sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or variations in dimensions, can be created in a single molding process. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

This time, the ACS-5000 is available as a facial recognition terminal compatible with FaceMe Security's add-on feature "Face Terminal," enabling access control management that combines "advanced anti-spoofing features" with high-speed facial recognition powered by edge AI. ■ Main Features 1. Accelerated Authentication Processing FaceMe Security is optimized for the MediaTek Genio 700's NPU, achieving faster facial recognition processing and reduced CPU load compared to processing solely on the CPU. It ensures stable authentication without delays even during peak times such as clocking in and out, contributing to alleviating congestion. 2. Advanced "Anti-Spoofing" Optimized for the IR + RGB camera mounted on the ACS-5000, it can quickly detect fraudulent authentication using photos, videos, or 3D masks within 0.6 seconds, ensuring reliable identity verification. 3. Door Control Without Additional Equipment FaceMe Security can directly control the digital I/O of the ACS-5000, allowing for the construction of an access control management system without the need for additional equipment. This simplifies system configuration and reduces implementation costs.

This is an air leak tester for battery cases of electric vehicles (EVs). The battery case has the characteristic of being "large with a significant internal volume, and its structure may deform due to internal pressure." As a result, air leak testing generates "noise caused by its large size and capacity" and "noise caused by expansion or deformation due to internal pressurization." To mitigate this noise, this device features a newly developed smoothing function and a linear fitting correction function used in combination during measurement. Additionally, to achieve low-pressure control that is difficult to manage and to expand flow for large volumes, we provide a bypass box (CBU-600) equipped with an electro-pneumatic regulator for precise pressure control and a pressurization valve with a large effective diameter to supply high flow rates. Measurement methods: Work-Work comparison, Work-Master comparison, Fixed Master comparison Measurement pressure range: 10 kPa, 20 kPa, 50 kPa (depending on specifications) Gauge pressure sensor accuracy: ±2% F.S. Differential pressure sensor accuracy: ±0.5% F.S. Group settings: 0 to 31 groups Power supply voltage / Power consumption: AC100 to 240 V / 100 VA

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing.
