Card Rulings:C-Tech Science - Energy Materia Gate

- What this effect means is that this Field Spell cannot be activated unless you have an active Contiunous or Equip Spell Card and one Monster on the field with "Cyber-Tech" in it's name. It also means that it can't be removed from the field unless this criteria is met.
 *  This card cannot be activated nor removed from the field unless you control one "Cyber-Tech" spell and monster card.

Simply put, by avoiding to use Equip or Continuous Spell Cards with "Cyber-Tech" in it's name after it has been activated, it can't be removed from the field.
