Inkomba ye-MOS: Uhhavini wetafula ohlanganisa ukosa isinkwa, ukubhaka nokosa phezulu esikhaleni esincane esinomoya ojikelezayo. Ushisa ngokushesha kunohhavini ogcwele futhi usebenzisa amandla amancane ekuphekeni okuncane. Izindawo ezishintshekayo zeshalofu lezintambo zilungele konke, kusuka esinkweni esosiwe kuya kupizza engu-23 cm, okwenza ube inketho enomsoco lapho ukushisisa uhhavini ophelele kungadingeki.
