13fiber optic modular connector system which includes a receptacle connector (30) and a locking leaf spring (17) having a locking tang (17c) mounted on the receptacle connector. The connector system further includes a removable plug connector housing (19) carrying a rotatable coupling ring (23) for selective coupling with the receptacle connector. The coupling ring includes external splines (25) for accepting a connector installation and removal tubular wrench (50), and further includes a plurality of notches (27) for cooperating with the locking leaf spring to provide a rachet mechanism. The notches on the coupling ring and the locking leaf spring on the receptacle connector allow the coupling ring to be rotated in a first direction, and prevent rotation in a second direction when the locking tang of the leaf spring is engaged with one of the notches on the coupling ring. The disclosed connector system further includes a connector installation and removal tubular wrench (50) which has an elongated housing (35) and an internally splined socket (39) for selectively meshing with and engaging the external splines of the plug connector coupling ring. An elongated slot (47) extending from the end of the socket along the housing is provided to allow the tubular wrench to be placed over a removable plug connector having a fiber optic cable connected thereto.

An electrostatic dissipating fabric (10) constructed of woven or knitted base fabric (12, 14) having an integrally woven or knitted grid structure which is raised above the surface of the base fabric thereby resulting in increased electrostatic dissipation performance. The grid is formed from a static discharge yarn (16, 18) plied to a carried yarn which is then woven or knitted into the fabric in the warp direction, the fill direction or both, thereby producing a fabric which exhibits the rapid yet controlled dissipation of static electricity into the art. Such fabric can be used for anti-static garments, anti-static covering cloths, filtration media and the like.

 Appl.No PCT/JP1981/000391 Applicant HIRANO, Nobukazu Inventor HIRANO, Nobukazu
A skeletal bar freely detachable and exchangeable on a bridge fixed onto the surface board of a guitar to serve to determine the length of each string. The conventional skeletal bar is linearly partitioned for the strings. Hence, the interval errors that occur upon pressing a string with left-hand fingers due to the thickness of the string are different according to the string, and even world famous musical instruments cannot provide accurate intervals. This skeletal bar is improved by varying the contact of the string in accordance with the thickness of the string in a range of the thickness of the bar, and hence increasing the length of the string for the thick string which would have caused a large interval error, thereby eliminating the interval error. Consequently, tuning which heretofore required considerable experience and skill can be simply performed, the sound and echo of the musical instrument become clear, an accurate sense of intervals can be trained, and in addition, various problems caused by bad intervals can be overcome. As one preferred embodiment, a skeletal bar in which the contact of the bar with the string is machined in two oblique lines in two groups for nylon or steel strings and metallic strings. (Fig. 1). As another embodiment, a skeletal bar in which the contact of the string is machined forward for a slender string, is centered for a middle string, and rearward for a thick string within the range of the thickness of the bar. (Fig. 6).
