Title: Tsutomu Tobita: Innovator in Discharge Tube Manufacturing
Introduction
Tsutomu Tobita is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of discharge tube manufacturing, holding a total of 5 patents. His innovative approaches have advanced the technology used in this specialized area.
Latest Patents
One of Tsutomu Tobita's latest patents is a method for manufacturing discharge tubes using heat for the oxidation of the adhesion area of the electrode lead. In this process, electrode clamps are attached to both sides of an electrode lead, except on a predetermined adhesion area, to fix a glass bead. The power section is then driven to energize the area between the electrode clamps, heating and oxidizing the surface of the predetermined adhesion area. This allows the glass bead to be welded to the oxidized surface effectively.
Another significant patent is related to an electrode producing method. This method involves a flash discharge tube that includes a pin-shaped cathode. The pin-shaped cathode has an electrode core made of tungsten with a first end portion, while a nickel lead has a second end portion connected to the first. The electrode core and the lead are retained using first and second chuck mechanisms, which push the end portions against each other while supplying electric current. This process enables resistance welding of the electrode core and the lead.
