Latest Patents

Fujiwara's latest patents include an innovative electromagnetic relay device. This device features a mover that includes a movable contact, which can abut onto and separate from a stationary contact through a defined contact region. A plunger is utilized to cause the mover to reciprocate, enabling the movable contact to interact with the stationary contact effectively. Additionally, the electromagnetic relay device comprises a solenoid unit that includes an electromagnetic coil, a movable core, and a support member that supports the outer peripheral surface of the movable core's slidable contact portion. A movable wall member is also integrated into the design, which reciprocates with the plunger and occupies a specific region within the device.

Another of his patents describes an electromagnetic relay that consists of a coil and a housing that supports the coil. This relay features a non-movable portion that includes a fixed core and a fixed magnetic path defining member. The movable portion is designed to be reciprocally movable along the center axis line of the coil, responding to the energization state of the coil. The movable core is positioned to face the fixed core, and it includes a flange portion that defines a separation distance and/or a facing area in the magnetic gap.
