Summary of the patent applications from SUMITOMO ELECTRIC INDUSTRIES, LTD. on November 30th, 2023

SUMITOMO ELECTRIC INDUSTRIES, LTD. has recently filed several patents related to various technologies. These patents cover areas such as optical modules, shield connectors, optical connector modules, optical receivers, coupling members, synthetic single crystal diamonds, diamond sintered materials, fluorine-containing silica glass, and service hole covers for vehicle door panels.

In the field of optical modules, one patent application describes an optical module that includes an optical semiconductor element, a stem with signal and ground pins, and a circuit board. The circuit board has signal and ground through-holes that are pierced by the respective pins, and the signal line on the board is electrically connected to the signal pin. The aim of this patent is to improve the shielding performance of the module.

Another patent application focuses on shield connectors, aiming to simplify their design while maintaining their shielding performance. The shield connector includes a dielectric, an inner conductor, and an outer conductor made of a metal plate material. The outer conductor consists of a box-shaped body portion and a receptacle, and a mating outer conductor can fit into the receptacle.

In the field of optical connector modules, a patent application describes a connector designed to be connected to an optical component in a specific direction. A connecting member is included to maintain the connected state between the connector and the optical component, and it can rotate in contact with the connector while being engaged with both the connector and the optical component.

In the area of optical receivers, a patent application describes a receiver that includes a beam reducer and a light receiving element. The beam reducer consists of an incident lens and an emitting lens, and the receiver's main body is located between them. The light receiving element includes a light receiving lens and a light receiving portion for further processing the received light.

Other patent applications cover topics such as coupling members used to connect optical components to connectors, synthetic single crystal diamonds with specific boron atom compositions, diamond sintered materials with high diamond grain content and specific dislocation densities, methods for producing fluorine-containing silica glass, and service hole covers for vehicle door panels.

Notable applications:

  • Optical module with improved shielding performance
  • Simplified design of shield connectors while maintaining shielding performance
  • Optical connector module with a connecting member for maintaining a connected state
  • Optical receiver with a beam reducer and a light receiving element
  • Coupling member for connecting optical components to connectors
  • Synthetic single crystal diamonds with specific boron atom compositions
  • Diamond sintered materials with high diamond grain content and specific dislocation densities
  • Method for producing fluorine-containing silica glass
  • Service hole cover for vehicle door panels.
