Abstract: A connector is provided to improve the reliability of a primary locking function by an elastic lock piece without deteriorating a secondary locking function and an insufficient insertion detecting function of a retainer. When female terminals (20) are properly inserted, a retainer (30) can be pushed to its fully fitted state or full lock position since elastic lock pieces (14) are not located in deformation permitting spaces (15). When there is/are insufficiently inserted terminal(s) (20), the retainer (30) cannot be pushed to its fully fitted state or full lock position since it comes into contact with the elastic lock pieces (14) in the spaces (15). Since a lock projection and the elastic lock piece (14) are locked outside the terminal (20), a large engaging space of the lock projection (23) with the elastic lock piece (14) can be ensured without restricting a projecting amount of the lock projections (23) by the internal construction of the terminals (20).

A fuse box 13 into which a compact integrated fuse 14 is fitted is arranged on the upper surface of the FPC 19, and upstream and downstream contact surfaces of narrowly and parallelly arranged fusible elements 34 of the fuse 14 are connected with the wires 16 and the FPC 19, respectively.

Abstract: A laser system is provided for precisely locating points in space relative to a reference plane. The system includes at least one laser generator capable of sweeping a plurality of mutually perpendicular laser planes and/or one laser plane and one laser beam perpendicular thereto. The system further includes a plurality of laser sensitive targets. Three laser sensitive targets are positioned to lie in the first plane swept by the laser generator. These targets then define a reference plane. The laser generator may be moved periodically and bucked into the previously established reference plane. The second laser plane or the laser beam will be perpendicular to the reference plane at each optional position of the laser generator. Thus, each second laser plane or each second laser beam will be parallel to one another. The system may further include position sensors for precisely defining distances between the parallel laser planes or parallel laser beams.

Abstract: Fixed electrodes 40 and terminals 30 are mounted on a casing main body 21 of a breaker device 10 with bolts 50. Each terminal 30 is firmly fixed between the end surface of a spacer 52 fitted on the bolt 50 and a mount base 24 by a fastening force of the bolt 50, and each fixed electrode 40 is pressed against the terminal 30 by an elastic force of a spring washer 52 fitted around the spacer 51 and is mounted such that it can be inclined by deforming the spring washer 52 by a remaining deformation margin. Accordingly, when the fixed electrode 40 is pushed by the movable electrode 44, the inclinations of the fixed electrodes 40 are automatically adjusted to reduce a sliding resistance which acts between the movable electrode 44 and the fixed electrode 40, thereby facilitating the switching operation.

Abstract: An electric noise suppressor is provided for suppressing high-frequency electric noise which comprises a thermoplastic housing and two ferrite members disposed therein. The thermoplastic housing is formed from two hingedly connected case halves, which are substantially identical. A ferrite member is secured to each case half by a laminated compressible adhesive-foam element, which is comprised of a resilient foam core layer and opposing adhesive layers disposed thereabout. Due to the resiliency of the foam core layer, the ferrite members are pressed into tight engagement within the thermoplastic housing. The end walls of the thermoplastic housing are formed with circular apertures, which are each formed with a diameter which is slightly smaller than the diameter of the cable which is engaged by the electric noise suppressor. The dimensional differences between the cable and the apertures allows the end walls to grippingly engage the cable at a predetermined location.
