摘要： PROBLEM TO BE SOLVED: To provide a small-type electrostatic relay of a power-saving type, and a manufacturing method thereof. SOLUTION: A normally closed movable contact 36 provided on a movable piece 32 comprising a semiconductor crystal base material rotatably supported through a pair of hinge parts 33, 34 above a fixed contact block 10 is higher than a normally opened movable contact 35. In the case where a voltage is not applied to an electrode 15 for driving and the movable piece 32, the normally closed movable contact 36 is in contact with normally closed fixed contacts 13, 14c. In the meantime, as a voltage is applied to both of them to generate electrostatic attractive force, the movable piece 32 is rotated about hinge parts 33, 34 as support points, and the normally opened movable contact 35 gets in contact with a normally opened fixed contact 12 and a common fixed contact 14.

摘要： PURPOSE:To provide a smooth motion characteristic, prolong the lifetime, and prevent generation of abrasion dust with a simple structure by locating the rotational axis of a moving iron on one plane with the rotational axes of movable contacting pieces. CONSTITUTION:The swell 31 of a moving iron 30 is attracted to the pole 42a of an electric magnet block 40 and held rotatable, and the rotational axis of the moving iron 30 is located on one plane with the rotational axes of movable contacting pieces 22, 23. When a voltage is impressed on a coil 46, the left end 30a of the moving iron 30 is attracted to the lefthand pole 41a of an iron core 41, and the moving iron 30 rotates round the ridge 31a against the magnetic force of a permanent magnet 42. thus the right end 30b separates from the righthand pole 41b, and the left end 30a is attracted to the lefthand pole 41. Therefore, movable contact 22a of contacting pieces 22, 23 separates from the stationary contact 11a, and the movable contact comes in contact with the stationary contact.

摘要： PURPOSE:To relax the adhesion of a contact by making the contact surface layer of a movable contact or a fixed contact with a gold-nickel alloy including less then 3 % nickel, or a gold-palladium alloy including less than 30 % palladium. CONSTITUTION:The surface layer of either a movable contact or a fixed contact is made of a gold-nickel alloy or a gold-palladium alloy, and the content of the nickel in the gold-nickel alloy is set less than 3 %, while the content of the palladium in the gold-palladium alloy is set less than 30 %. In a contact mechanism 30, for example, a movable contact 33 is made by forming a surface layer 33b of gold-1%neckel alloy over a silver liner layer, while the fixed contact 35 at a constantly-closed side and the fixed contact 37 at a constantly- opened side are made by forming surface layers 35b and 37b of gold-1% nickel alloy over silver liner layers 35a and 37a. A contact mechanism 30' is also made in the same manner. In such a composition, even though the unit is cleaned by supersonic waves, the adhesion of the contact is relaxed, the initial operational voltage can be made lower, and moreover, the contact resistance is stabilized, resulting in the improvement of the operational performance.

摘要： PROBLEM TO BE SOLVED: To provide a high frequency relay by which the number of part items and assembling manhours can be reduced and which is excellent in assembling workability by integrally forming a contactor block by connecting a contactor, a grand relay terminal, a shielding connecting part and movable contact pieces to each other. SOLUTION: In a high frequency relay, an armature block 40 is constituted by integrally forming a grand relay terminal 43 and movable contact pieces 44 and 45 in an almost central part of a armature 41 through a support body 42 by outsert molding. The movable contact piece 45 is formed by connecting one end parts of movable parts 45a juxtaposed on both sides of the armature 41 and one end part of an almost U-shaped shielding connecting part 45b to each other, and is integrally formed with the armature 41 by performing insert molding. A support projecting part 41c of the armature 41 is placed on an upper end surface of a permanent magnet 30, and a connection receiving part 43a of a grand terminal 23 by insert molding is integrally welded to a base block 20, and movable contact points 44c and 45c are opposed so as to alternately contact with and separate from fixed contact points 24a and 25b.

摘要： PROBLEM TO BE SOLVED: To provide a mechanical contact mechanism excellent in vibration resistance, frequency characteristic, and insulation by providing a fixed contact on the lower surface of the insulator substrate of a stationary-contact block in such a way that it faces the movable contact of a movable-contact block in such a manner that it can move into and out of contact with the movable contact. SOLUTION: A leading part 22a is plated with Au or Ag its end to form a movable contact 14, after which a recess 12 is formed by etching of a silicon wafer 11 to obtain a movable-contact block 10. A stationary-contact block 30 is stacked on the edge of the upper surface of the block 10 via a circular spacer that is quadrant on plan view, and a movable contact 14 is opposed to a fixed contact 32 at a predetermined contact-to-contact distance in such a way that it can move into and out of contact with the stationary contact. If no voltage are applied to driving electrodes 19, 20, a piezoelectric thin film 18 is not warped, and the contacts 14, 32 are separated. If voltages are applied to the electrodes 17, 20, the thin film 18 is warped with its upper surface projecting, and a movable piece 13 pushes up the contact 14, bringing the contact 14, 32 into contact to close an electric circuit.

摘要： PURPOSE:To increase the yield by a method wherein, after winding a coil around the barrel of a spool, the terminal parts of coil terminals are bent in almost a right angle. CONSTITUTION:Coil terminals 44, 45 are insert-molded so that terminal parts 44b, 45b may protrude from the flange parts 43a, 43b, 43c provided on one end part of a spool 43 almost in parallel with the axial core direction of the spool 43. Next, after winding a coil 46 around the barrel of the spool 43, the terminal parts 44b, 45b are bent in almost a right angle with the axial core direction of the spool 43. Through these procedures, after winding the coil 46 around the barrel of the spool 43, the terminal parts of coil terminals are bent in almost a right angle so that the wound up coil 46 may be neither caught by the terminal parts of the coil terminals nor disconnected for increasing the yield.
