光洋産業 Company Profile

Guidelines for business continuity have suggested measures for infection prevention in restaurants, such as partitioning customer seating and installing barriers between cash registers and customers in retail stores. Antimicrobial vinyl curtains have been available for a long time, but for virus protection, a "virus-resistant" performance is necessary. Additionally, acrylic panels placed on floors or tables can obstruct ventilation, so we recommend using vinyl sheets as a countermeasure. For infection control in homes, care facilities, and welfare institutions, installing roll screens at entrances, hallways, halls, and living rooms allows for ventilation when in use and easy retraction when passing through. We also offer hanging curtain types for reception areas and bedside in medical institutions. The flame-retardant transparent vinyl provides a sense of openness while blocking droplets at close range, significantly reducing infection risk and allowing for face-to-face communication. The fire from a stove can reach vinyl curtains or disinfectants... News of complete burns in wooden two-story stores has been reported, and there has been an increase in fires in restaurants and homes since last year. Many may have installed non-flame-retardant vinyl sheets, but from a fire safety perspective, there is a growing possibility of receiving warnings from the fire department in the future.

【High-Frequency Electromagnetic Wave Absorbing Sheet】 This is a thin sheet that absorbs high-frequency electromagnetic waves. We propose product forms tailored to needs, including layers of adhesives. This product excels in electromagnetic wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and has excellent durability. It is ideal for countermeasures against TX-RX interferences in modules such as ETC (5.8GHz), X-band (8-12GHz), ship radar (3GHz, 9GHz), proximity radar (24GHz), high-speed wireless transmission (38GHz), high-speed wireless LAN (60GHz), and vehicle-to-vehicle radar (76GHz), as well as for absorbing unwanted radiated noise, addressing misoperation due to ETC multipath reflection, and ghosting issues caused by nearby metallic structures in radar applications. 【Electromagnetic Wave Shielding Fabric】 ● Compared to shielding measures using metal, it is lightweight and easy to handle. ● Ventilation holes: By using highly breathable conductive fabric, shielding at the hole areas is possible. ● It shields low-frequency magnetic fields and has excellent high-frequency shielding performance, with outstanding breathability and flexibility typical of fibers/fabrics. It is lightweight and has excellent processability for sewing and cutting, using polyester threads that do not generate dust.

●One day, if the electronic tag (RFID) is affected by interference, it might be a good idea to use this guide to take countermeasures. ●The improvement measures implemented from the issues are published with photos. ●The construction procedure for the wall includes explanations with photos on the overlap of aluminum sheets, the pitch for tacker fixation, and the method of fixing with aluminum tape. ●Measures for leakage from outlets and embedded lighting fixtures that occurred during actual construction are also noted. Due to the recent pressure on radio waves leading to frequency shifts and reorganization, as well as the increase in RFID users and other wireless devices, there are not a few cases where acquired radio interference and other issues arise from these effects. The UHF band IC tags have a long communication distance of about 3 to 5 meters, which makes it easy to interfere when multiple IC tag readers are installed in close proximity. Particularly in Japan, the bandwidth allocated to UHF band IC tags is narrow at 2 MHz (for high-output types, while low-output types like handheld devices have 3 MHz), making it difficult to avoid interference. Wireless sensor networks utilize the high radio reach of the 920 MHz band and accelerate wireless IoT solutions through high reliability via multi-hop communication.
