Latest Patents

Oinuma's latest patents include a method for making a fluorescent lamp. This innovative method involves creating a fluorescent lamp from a pair of molded, flat glass shells. Substantially semi-circular recesses are formed on each shell at the bonding surfaces, which align with the recesses on the opposite shell. When bonded together, these shells create a circular orifice for the lamp. An exhaust tube is integrated, with a stem affixed to one end, securing an electrode filament and a getter plate within the space between the bonded shells. The gases in this space are exhausted, and mercury along with an inert gas is injected before sealing the exhaust tubes. Another patent describes a fluorescent lamp constructed by joining two glass shells, where at least one shell is molded. A recess is formed on the jointing surface, which becomes circular when the shells overlap. An exhaust tube and lead-in wires are hermetically fixed in the recess, while an anode getter plate is arranged independently from the electric circuit.
