Title: Jumper device for aerial wire winding type or longitudinal placement type optical cable
Inventor: OKUBO YOSHITADA
IPC: G02B6/46
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To prevent the exertion of undue tension on an optical cable which is put-on with a protective tube on its jumper part by housing this optical cable into a reinforcing wire-contg. protective pipe. SOLUTION: The optical cable 7 wound around an aerial wire 1 is housed in the reinforcing wire-contg. protective pipe 9 in the state of putting the protective pipe 19 on its jumper part over the entire length thereof. When the protective pipe 19 is put on the optical cable 7 and the cable is housed into the reinforcing wire-contg. protective pipe 9 in such a manner, the position of the optical cable 7 is restricted and the optical cable 7 eventually passes the center of the pipe part of the reinforcing wire-contg. protective pipe 9 regardless of the operator's skill and, therefore, the length of the reinforcing wire-contg. protective pipe 9 and the length of the optical cable 7 therein are made the same.  In addition, the optical cable 7 is integrated with the reinforcing wire-contg. protective pipe 9 and, therefore, the undue tension does not act on the optical cable 7 any more even if there are the lateral swing, etc., by the temp. change and wind of the aerial wire.

Filed: 1987-11-17
Abstract: PURPOSE:To quicken the switching speed by turning on a transistor(TR) connected between a base and an emitter of an output invert TR with an input voltage changes from L to H. CONSTITUTION:A TR T8 connected between the base and emitter of the output invert TR T7 and an AND circuit 3 are provided. With an input voltage VIN going from L to H, the TR T7 is not instantly turned off by a charging electric charge of a parasitic capacitor C of the base and emitter and an output voltage VOUT is at an L level. The output level of the AND circuit 3 goes to H for a period only while the input voltage VIN is at H and the output voltage VOUT is at an L level to turn on a TR T8. As a result, the charging electric charge in the parasitic capacitor C of the TR T7 is discharged instantly via the TR T8 and the TR T7 is turned off and the output voltage VOUT goes to H. Thus, the switching speed is quickened.
