光洋産業 Company Profile

Guidelines for business continuity have suggested infection prevention measures for restaurants, such as partitioning customer seating and installing barriers between cash registers and customers in retail stores. Antibacterial vinyl curtains have been available for a long time, but for virus protection, "antiviral" properties are necessary. Additionally, acrylic panels placed on floors and tables can obstruct ventilation, so measures using vinyl sheets are recommended. For infection control in residences, care homes, nursing, and welfare facilities, installing roll screens at entrances, hallways, halls, and living rooms allows for ventilation when in use and one-touch raising when passing through. We also provide hanging curtain types for reception areas and bedside in medical institutions. The flame-retardant transparent vinyl does not create a sense of pressure, blocks droplets at close range, significantly reduces infection risk, and allows for face-to-face communication. The fire from a stove can reach vinyl curtains or disinfectants... News of wooden two-story stores being completely burned down has been frequent, and there have been many 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 your needs, including laminated 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 coupling 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 metal structures in radar applications. 【Electromagnetic Wave Shielding Fabric】 ● Compared to shielding measures using metal, it is lightweight and easy to handle. ● Ventilation holes: High breathability conductive fabric allows for shielding at the hole areas. ● It shields low-frequency magnetic fields, has excellent high-frequency shielding performance, and offers 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, I think it would be good to use this guide to take countermeasures. ●Improvements implemented based on 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, it is not uncommon for issues such as radio wave interference to occur as a result of these influences. UHF band IC tags have a long communication distance of about 3 to 5 meters, which can lead to interference when multiple IC tag readers are installed in close proximity. In particular, 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, through high reliability via multi-hop communication, are accelerating wireless IoT solutions.
