摘要： An electromagnetic relay is provided which is small in size and is capable of controlling two circuits of an ordinarily-open contact, which has a large current-carrying capacity and high interrupting capability, and which is excellent in resistance against shock and vibration. Movable contactors are held, through bow-shaped movable contactor springs, to two -shaped holding frames each being electrically separated and being mechanically connected via a card made of a highly heat-resistant resin in a card block. Thick-plate shaped movable contacts, which are attached to the movable contactors in a fixed manner, are electrically connected or disconnected to fixed contacts in a base block, in synchronization with operations of an armature of an electro-magnet block. In order to improve a current-carrying capability and interrupting capability, there are provided two pieces of ordinarily-open contacts which are connected in series to each other, and between which an interval is doubled, in each of two circuits.

摘要： A variable optical attenuator comprises an incoming fiber for propagating an incoming light beam, a mirror for reflecting the incoming light beam as a reflected light beam and an outgoing fiber for propagating as an outgoing light beam at least one part of the reflected light beam. The light intensity of the outgoing light beam is determined by the angle of reflection at the mirror. The angle of reflection at the mirror is adjusted by an actuator for rotating the mirror. The actuator comprises a plate, a coil, a housing and permanents magnets. The mirror and the coil are fixed on the plate. The housing supports the plate so that the plate is able to rotate around a rotation axis, which is included on a predetermined plane. The permanent magnets are fixed on the housing and generate predetermined magnetic flux density along the predetermined plane. When a driving current is supplied to the coil under the predetermined magnetic flux density, a Lorentz force occurs at the coil so as to rotate the coil. Together with the coil, the mirror rotates so that the light intensity of the outgoing light beam can be adjusted.
摘要翻译：可变光衰减器包括用于传播入射光束的入射光纤，用于反射作为反射光束的入射光束的反射镜和用于作为输出光束传播至少一部分反射光束的输出光纤。出射光束的光强度由反射镜的反射角决定。通过用于旋转镜子的致动器来调节镜子处的反射角度。致动器包括板，线圈，壳体和永磁体。镜子和线圈固定在板上。壳体支撑板，使得板能够绕包含在预定平面上的旋转轴线旋转。永久磁铁被固定在壳体上并沿预定平面产生预定的磁通密度。当以预定的磁通密度向线圈提供驱动电流时，在线圈处产生洛仑兹力以使线圈旋转。与线圈一起，镜子旋转，从而可以调节出射光束的光强度。

摘要： An electromagnetic relay apparatus, which is improved in miniaturization, performance, assembly accuracy, cost reduction, productivity, and reliability. A plurality of electromagnetic relays, each having an NO contact that is closed by applying exciting current to a coil and an NC contact that is closed when the excitation current is not passed through the coil, are arranged in line, one diagonally opposite to the next, on a base so that the respective NO/NC contacts of adjacent electromagnetic relays are located in diagonally opposed positions in substantially point symmetrical relation. The electromagnetic relay includes an electromagnetic block having a couple of moving contacts, a first stationary contact and a second stationary contact both being connectable to external wiring, which are composed of uniform parts or components.

摘要： A electromagnetic relay includes a spool, a coil, a U-shaped yoke, an armature, a movable contact, a pair of stationary contacts, and a taper. The spool has an inner hole and first and second flange portions formed at its two ends. The coil is wound on the spool. The yoke is locked at the flange portions of the spool by press fitting to stride over the coil. The armature is movably connected to one end of the yoke and positioned to extend through the inner hole of the spool. The movable contact is attached to move in an interlocked manner with the armature. The pair of stationary contacts are arranged to sandwich the movable contact. The taper is formed on at least one of press-fit locking surfaces of one end of the yoke and the first flange portion, and has a locking force that increases as being closer to a vicinity of the inner hole of the spool. A method of adjusting an electromagnetic relay, and a method of assembling an electromagnetic relay are also disclosed.
