摘要： An electrostatic relay essentially comprises a fixed electrode with a fixed contact insulated therefrom, a movable electrode plate with a movable contact insulated therefrom, and a fixed pair of oppositely charged electrets. The movable electrode plate is pivotally supported at a pivot in a cantilever fashion or a seesaw fashion, and also to move about the pivot axis relative to the fixed electrode between two rest positions of closing and opening the contacts. A control voltage source is connected across the fixed electrode and the movable electrode plate to generate a potential difference therebetween. The electrets are disposed adjacent the movable electrode plate to generate electrostatic forces attracting and repelling the movable electrode plate, respectively, when the movable electrode plate is charged to a given polarity. That is, the attracting and repelling forces are cooperative to produce a torque for moving the movable electrode plate in one direction from one of the rest positions to the other. The electrostatic relay is useful for precisely and rapidly operating the relay.

摘要： An improved magnetic actuator mechanism suitable for dot printing mechanisms for use in a wire matrix dot printer. The present magnetic actuator mechanism comprises an armature movable between a reset position and an actuated position, a permanent magnet for attracting the armature toward the reset position, and an electromagnet which, when energized, generates in the armature a magnetic flux opposite to and larger than the magnetic flux generated therein by the permanent magnet. The armature is thus moved to the actuated position by the turn of the magnetization direction in the armature when the electromagnet is energized. Therefore, in the present invention, the armature can have the magnetic fluxes in the opposite directions by the action of the permanent magnet and electromagnet combination so as to provide the armature of smaller cross sectional area or thickness with a higher magnetic force without causing the magnetic saturation thereof, which allows the use of an armature of less thickness or weight to assure high speed operation in response to a driving signal.

摘要： An electrostatic relay comprises at least one fixed base having a fixed electrode and an actuator frame having a movable electrode. The fixed base carries a pair of fixed contacts insulated from the fixed electrode. The movable electrode carries a movable contact insulated from the movable electrode. The movable electrode extends along the fixed electrode and is pivotally supported at its one longitudinal end relative to the fixed base so as to pivot between two contacting positions of closing and opening the movable contact to and from the fixed contacts. The movable contact is formed at the other longitudinal end of the movable electrode. A control voltage source is connected across the fixed electrode and the movable electrode to generate a potential difference therebetween for developing an electrostatic force by which the movable electrode is attracted toward said fixed electrode to move into one of the two contacting positions. The electrostatic relay is characterized in that the movable electrode is cooperative with the fixed electrode to define therebetween an elongate gap which is narrower toward the one longitudinal end about which the movable electrode pivot than at the other longitudinal end of the movable electrode at which the movable contact is carried.

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： The acceleration applied to a selected device such as a magnetic disc drive system can be detected by the use of an acceleration detector having at least one piezoelectric acceleration sensor unit. The sensor unit includes a piezoelectric element, a supporting member for the piezoelectric element and two electrical leads. The piezoelectric element is formed with a pair of elongate sheets made of a piezoelectric ceramic and an intermediate insulation layer interposed between the elongate sheets to generate a voltage difference instantaneously therebetween in response to the acceleration of the acceleration detector. The support member is made of an electrically insulating resin, and has a concave which is formed with side and bottom walls and a top opening. The side wall is provided with a slit in which the piezoelectric element is tightly caught in such a manner as to divide the concave into two open-chambers and be supported by the support member in a cantilever fashion. The electrical leads extend into the concave to make electrical connections between the elongate sheets and the electrical leads. In the present invention, since the piezoelectric element can be attached accurately at a predetermined direction to the supporting member by forcing it into the slit, it is possible to stably supply the acceleration detector having excellent sensitivity to the acceleration without causing variations in detecting direction of the acceleration.
