Latest Patents

One of Oyama's latest patents is a semipermeable membrane support. This invention features polyolefin-based fibers that can withstand repeated washing and backwashing. It facilitates easy permeation of the semipermeable membrane component while preventing it from striking through. The support exhibits excellent adhesion to the semipermeable membrane and between its non-coating surface and a resin frame. The semipermeable membrane support is a wet-laid nonwoven fabric made from core-sheath type conjugate fibers, with polypropylene as the core and polyethylene as the sheath. It boasts a burst strength of 300 to 1,000 kPa, along with superior Bekk smoothness and mirror surface glossiness.

Another notable patent is the capacitor block having a spacer. This invention aims to provide a solid electrolytic capacitor separator that reduces thickness non-uniformity and minimizes the likelihood of internal short-circuits. It ensures that the impedance remains manageable while exhibiting high heat resistance. The separator includes non-woven fabric made from fibrillated heat-resistant fibers and synthetic short fibers. The fibrillated heat-resistant fibers have a specific length and percentage that contribute to the overall effectiveness of the capacitor.
