    摘要： An electromagnetic relay has a base provided with an insulation enclosure and with a contact block outwardly of the enclosure. An electromagnet block is received within the enclosure and includes a coil, yokes, and an armature extending through the coil along the length of the enclosure. The armature is magnetically coupled to the coil and is movable relative to the yokes upon energization of the coil. A card is provided to connect the armature and a movable contact of the contact block for closing and opening the contact. A cover fitted on the base includes an insulation partition which extends between the enclosure and the contact block to accomplish a double-wall insulation between the electromagnet and the contact block. The card has a trunk for connection with the armature and a crosspiece for connection with the movable contact. The trunk extends into the enclosure through a front is opening thereof to fit around the end of the armature such that the entire length of the armature is insulated from the contact block by the enclosure and by the trunk. The crosspiece extends from the trunk longitudinal outwardly of the enclosure for connection with the movable contact outwardly of the insulation enclosure and partition. Further, the partition is contiguous along substantially the entire length of the enclosure. With these features, the relay can have an improved double-wall insulation between the electromagnet block and the contact block without leaving any insulation break along the length of the electromagnet block.

    摘要： A matrix relay is formed with a plurality of latching relays arranged in a matrix and mounted on a base of an electrically insulative material. Each of the latching relays comprises an excitation coil, permanent magnet, a pair of first and second fixed contacts, and an armature carrying a pair of first and second movable springs each providing movable contacts. The armature is magnetically coupled to the excitation coil so as to be movable in response to energization of the coil by current of selective polarity between close and open positions of the fixed and movable contacts. A plurality of the armatures of the latching relays arranged in a row of the matrix are assembled into a single armature block to be mounted on the base as a single unit. The armature block comprises a single pair of first and second supporting members made of an electrically conductive material. All of the first movable springs and all of the second movable springs of the latching relays of the armature block are connected respectively to the first and second supporting members mechanically and electrically, so that two row paths for electrical signals common to the latching relays arranged in the row of the matrix are provided. This simplification of the structure and electric circuit of the matrix relay would be useful to small-size the matrix relay without complicated fabrication process.

    摘要： In a brushless motor, during a synchronized operation mode, n kinds of driving waveforms having the first to n-th patterns are sequentially outputted and the outputting of the n-th pattern is followed by cyclically outputting the patterns again in a sequence from the first pattern, thereby generating a rotating magnetic field in an armature winding. Upon transition from the synchronized operation mode to a rotor position detection operation mode, the commutation signal is changed over from the synchronizing signal to a signal based on the rotor position detector signal after the (n-1)th pattern has been outputted and at a timing when the n-th pattern is to be subsequently outputted. Thereby, upon transition from the synchronized operation mode to the rotor position detection operation mode, the commutation signals are linked in a proper sequence so that smooth mode transition becomes possible without the addition of any special ancillary circuit.
