Abstract: An assembling device for releasably fixedly securing first and second plate-like members together includes a main case mounted on the first member and having an opening for receiving therein a hook member fixed to and projecting from the second plate-like member. A rotary body is rotatably disposed in the main case and includes structure defining a cylindrical inner surface which faces and is eccentric with a rotary shaft, the cylindrical inner surface being engageable with the hook member. A retaining mechanism is provided which yieldably retains the rotary body rotationally fast with the main case at a predetermined rotational position. Rotation of the rotary body causes relative reciprocal motion between the hook member and the main case such that the hook member reaches a desired position relative to the main case, whereby the first and second members are releasably fixedly secured to each other.

Abstract: An electric noise absorber for attaching to a wire of an electronic device comprises a magnetic body divided into parts, a holding case composed of two case members and a locking device for preventing a movement of the magnetic body in the holding case. Each abutment surface of the two parts of the magnetic body cut by a cutting plane are sufficiently larger in area than a basic cross section of the magnetic body in order to prevent magnetic resistance of the abutment surface from being increased. Further, the dislocation of the two parts of the magnetic body can be prevented by the locking device. As a result, the magnetic body is securely held in the holding case to absorb noise curent effectively.

Abstract: A tuning mechanism for harmonically tuning and pitch tuning guitar strings. The mechanism is part of the bridge. It includes a base and a plurality of saddles which are mounted on the base and are slidable longitudinally back and forth to adjust the effective length of the strings of the guitar. Each saddle is mechanically connected to a guide member which is located in a groove in the base. A tuning screw through the guide member slides the guide member and the saddle back and forth to tune a guitar string. A securing bolt is then tightened to fix the saddle in place on the base. The mechanism also includes a pivotable pitch tuning member which pivots back and forth in response to a pivoting force applied by a pitch tuning screw to adjust string tension. The string receiving end of each saddle can be raised or lowered to adjust the height of the string above the base.

Abstract: A bridge and means for mounting the rear end of each of a plurality of strings on said bridge, the bridge including a plurality of saddles to which strings are individually attached wherein each saddle is adjustable longitudinally of the string in order to vary the effective length of the string for harmonious tuning and the saddle is adjustable without varying the effective length of the string in order to provide a fine tuning variation in tension for pitch. The invention relates to the specific means of mounting the end of the string on its individual saddle of the bridge wherein a substantially tubular member is provided with a groove extending downwardly, substantially normal to the body of the instrument to which the bridge is secured. The string passes through said groove and a bead on the end of the string initially anchors the string with respect to the groove.
