Patent number: 9761970Abstract: A housing is configured to receive a plug that includes an upper face, a lower face, and a front face. The housing also includes a cutout portion that traverses the upper face and the lower face, opens to the front face of the housing, extends for a length of the plug, and is formed in a direction of insertion of the plug. An opening is configured to receive the plug, which is formed on the front face of the housing and connected to the cutout so that a plug is received by the opening. A distance from the upper face to the lower face of the housing is approximately equal to a diameter of the plug.Type: GrantFiled: November 14, 2014Date of Patent: September 12, 2017Assignees: Sony Corporation, Sony Mobile Communications Inc.Inventors: Koichi Izawa, Kiyohito Masuda

Patent number: 9312709Abstract: An apparatus includes a main body having an opening and a movable member configured to hold a plug capable of transmitting an electrical current to an external device. At least one of the movable member and the plug include a magnet. The movable member and the plug are arranged such that at least one connector of the plug extends beyond a plane parallel to the opening when the movable member is in a first state, the first state corresponding to a magnetic force between a ferromagnetic material and the magnet above a predetermined magnitude. The movable member transitions from the first state to a second state when the magnetic force is below the predetermined magnitude. When the movable member is in the second state, the at least one connector of the plug remains below the plane parallel to the opening.Type: GrantFiled: June 24, 2013Date of Patent: April 12, 2016Assignee: Sony CorporationInventors: Tsutomu Takahashi, Taro Takamoto, Koichi Izawa, Shintaro Nonaka, Tamio Nishino

Patent number: 9083112Abstract: The magnetic coupling connector includes: first and second connector main bodies to be coupled with each other; a magnet member disposed in a coupling portion of the first connector main body and a mate-side magnetic material disposed in a coupling portion of the second connector main body, the magnet member in the first connector main body adsorbing onto the mate-side magnetic material in the second connector main body, thereby coupling the connector main bodies together; and a contact terminal disposed in the coupling portion of the first connector main body and a contact terminal disposed in the coupling portion of the second connector main body, the contact terminals being pressed against each other when coupled. In the magnetic coupling connector, the magnet member is held by the first connector main body so as to be allowed to swing.Type: GrantFiled: February 17, 2014Date of Patent: July 14, 2015Assignee: SMK CorporationInventors: Kiyoshi Asai, Toshihiko Kato, Koichi Izawa, Shintaro Nonaka, Yutaka Nakaone

Patent number: 8853562Abstract: An electromagnetic shielding method includes the steps of disposing a flexible electromagnetic shielding film including a laminate of at least an insulating layer and a conductive metal layer to cover a portion to be electromagnetically shielded on a printed wiring board so that the insulating layer faces the printed wiring board, the conductive metal layer having a higher melting temperature than that of the insulating resin layer; and heating the electromagnetic shielding film to a temperature to melt and contract the insulating layer, thereby bonding the conductive metal layer to a grounding conductor of the printed wiring board and electrically connecting the conductive metal layer to the grounding conductor. The heating temperature is higher than the melting temperature of the insulating layer and lower than the melting temperature of the conductive metal layer.Type: GrantFiled: June 25, 2012Date of Patent: October 7, 2014Assignees: Sony Corporation, Sony Mobile Communications Inc.Inventors: Koichi Izawa, Yumi Ogura
