Latest Patents

Tethuya Uchida holds a patent for an "Apparatus for sealing a semiconductor element in a resin." This invention features a plunger that injects a resin pellet into the cavities of both upper and lower molds. The plunger is driven by a reciprocating mechanism through a flexible transmission member, allowing for non-parallel movement between the plunger and the mechanism. The preferred embodiment utilizes a ball screw mechanism powered by a servomotor, with a roller chain that is slidably positioned within the lower mold. Additionally, the lower mold can be longitudinally divided into multiple sections for easier manufacturing and disassembly. A ventilating mechanism is also included to circulate cooling air along the roller chain during the molding process, preventing damage from heat.
