IPC: H04R7/02
Filed: 1981-11-09
Abstract: PURPOSE:To improve a Young's modulus, internal loss and temperature characteristics by applying multiple mesh structure of thermosetting resin and crystal- line thermoplastic resin to a disphragm. CONSTITUTION:Thermosetting resin, e.g. 5-50wt% prepolymer of polyurethane and thermoplastic resin, e.g. 95-50wt% polypropylene are kneaded. Then, cross- linked polyether glycol equivalent to the prepolymer of polyurethane is added and further kneaded.

Title: End face polishing machine for ferrule of optical connector
Inventor: MASUKO TAKAYUKI
IPC: B24B19/00
Filed: 1986-07-30
Abstract: PURPOSE:To obtain the reproductibity of an excellent spherical surface being prevented from easily receiving an influence of scattered abrasives, by rotatably supporting a chuck member, which holds a ferrule in its rotary center so that the ferrule can be mounted and removed, by a supporting member. CONSTITUTION:A machine, which mounts a ferrule to the polished to holding members 34 fixedly supported to a bed 53, adapts each ferrule to a polishing surface by loosening a lever 54 to turn the bed 53 to the upper of a rough polishing disc 47 next to lower the bed 53, and an end face is rough polished by driving both the polishing disc 47 to rotate and a pulley 36 of the holding device 34 to normally and reversely rotate by a motor 52. Since the polishing surface of said polishing disc 47 is formed only by a pin plate, the end face of the ferrule is polished into a protrusive cone shape with an axis of symmetry. Next the machine, in which a polishing surface of polishing discs 48, 49, consisting of a copper plate provided to be glued on an elastic structure, performs shape polishing and finish polishing, finishes the end face almost into a spherical shape. In this way, the machine improves the reproductibity of the finished spherical surface further being prevented from easily receiving an influence of scattered abrasives.

Title: Spectacle frame of protective spectacles for laser light
Inventor: YAMAMOTO TAMENOBU
IPC: G02C5/14
Filed: 1988-07-18
Abstract: PURPOSE:To avert the danger by the high voltage of a laser device by forming the spectacle frame into the laminated structure in which metallic foil having high reflectivity to laser light is sandwiched by synthetic resin layers having an insulating characteristic. CONSTITUTION:The spectacle frame is made into the laminated structure in which the metallic foil 7 having the high reflectivity to the laser light is sandwiched by the synthetic resin layers having the insulating characteristic. The surface of the metallic foil 7 is formed to rough surface so that the laser light is irregularly reflect. The laser light is absorbed by the surface of the synthetic resin layers 8 when said surface is irradiated with the laser light. The synthetic resin layer 8 on the surface is then deformed by heat generation and smoke and smells are generated. However, there is the metallic foil 7 having the high reflectivity in the intervening layers and, therefore, the transmittance of the laser light is lowered in said foil. The generation of through-holes in the spectacle frame is prevented in this way and the laser light is irregularly reflected by the surface of the metallic foil 7. Since the laser light is diffused by the foil, the secondary hazard by the reflected light is thus eliminated.
