Title: Tape cassette
Inventor: KIKUTANI SATOSHI
IPC: G11B23/04
Filed: 1981-12-09
Abstract: PURPOSE:To prevent deteriorations in performance of a stretched tape caused by a finger and dust with a simple constitution, by protecting both surfaces of the tape stretched over an opening part of a cassette with a front cap and rear cap. CONSTITUTION:Both surfaces of a tape 2 stretched over an opening part 15 of a cassette are protected by a front cap 3 and rear cap 4, respectively. The front cap 3 is rotated and opened when the tying of a locking member 20 interlocked with a releasing member of a cassette garage is released when the cassette is inserted into a prescribed position of the cassette garage. When the cassette is lowered together with the garage under this condition, a cap opening arm 36 is rotated by a cap opening means and the cap 4 is opened and, at the same time, the cap 3 is also opened under an interlocked condition. Thus the caps 3 and 4 are opened only when a cassette is mounted on the record reproducing device. Therefore, the stretched tape is protected with a simple constitution even when the tape is stretched for a long distance, and deteriorations in performance of the stretched tape caused by the finger and dust can be prevented.

Title: Method of manufacturing composite electrode wire for electric discharge machining
Inventor: SANKI SADAHIKO
IPC: B23H7/08
Filed: 1982-11-12
Abstract: PURPOSE:To prevent the wire from making small kinds and to improve electric discharge machining properties, by regularly winding or rewinding a finish- elongated electric discharge machining wire coated with zinc or zinc alloy. CONSTITUTION:Although an electric discharge machining electrode wire consisting of a metal core of braze or the like with a diameter of 0.3mm. or less and zinc or zinc alloy coating the surface of the core and having a thickness of 10mu or more is excellent in electric discharge machining properties, the wire is likely to make small kinks due to the crossing of the wire in its winding around a bobbin because the wire is soft. The small kinks would have an eccentricity of as small as about 1.8mu in the period of 30 to 50mm. but exert an adverse effect on the speed and accuracy of electric discharge machining. After the finish- elongation of the electrode wire 1, it is regularly wound or/and rewound on a bobbin 2 to prevent the wire from making the small kinks.
