Title: Method and device for inspecting optical fiber with ultrasonic wave
Inventor: HATORI MASAMI
IPC: G01N29/07
Filed: 1984-08-10
Abstract: PURPOSE:To measure the distance to a rupture point, etc., accurately at any time by calculating the time difference between the pulse transmission time of an ultrasonic wave and the reception time of its reflected wave. CONSTITUTION:A timing signal outputted from a timing circuit 11 is transmitted from one terminal of an optical fiber cable 7 to be measured through a high-frequency signal driving circuit 2, directional coupler 3, matching circuit 4, transducer 5, and connector 6. If these is a rupture point on the cable 7, a reflected wave is generated at this rupture point, and this reflected wave is passed through the connector 6, transducer 5, circuit 4, and coupler 3, amplified 8, and inputted to an arithmetic circuit 9. A high-frequency signal outputted from the circuit 2 is inputted to the circuit 9, and the distance to the rupture point is computed 9 from the time difference between the high-frequency signal and high- frequency signal of the reflected wave reflected at the rupture point and the second velocity in the optical fiber and displayed on a display device 10. Thus, the distance to the rupture point is measured accurately all the time.

Title: Hot-melt adhesive for easily openable shrink packaging body
Inventor: TSUCHIYA MIKIAKI
IPC: B29C65/40
Filed: 1986-07-17
Abstract: PURPOSE:To obtain an adhesive agent, capable of being coated under a temperature, not exceeding the melting point of synthetic fiber, good in adhesive properties, developing a good bonding force in a low temperature and allowing the shrinkage of a tear tape itself, by a method wherein a viscosity, a softening point, an open time and a set time in a specified temperature are specified respectively. CONSTITUTION:The title adhesive agent is a hot-melt adhesive for shrink packaging body, provided with the viscosity of 100-20,000cps at 150 deg.C, the softening point of 65-120 deg.C and the open time and the set time are 0.5-10sec. When the adhesive is provided with the viscosity of up to 100cps, the adhesive is easily removed and bonding can not be effected when it is bonded to a shrink film by heating, however, when the viscosity exceeds 20,000cps, the processing of a thread becomes difficult. When the softening point is up to 65 deg.C, the adhesive is softened and the shrink thread is easily detached upon heating, however, when it exceeds 120 deg.C, the shrinkage of the shrink film is caused upon bonding a tear tape by heating. When the open time is up to 0.5sec, the curing of the adhesive is too fast, however, when it exceeds 10sec, the curing of the adhesive is too slow and the non-cured adhesive is adhered to an unnecessary part. When the set time is up to 0.5sec, insufficient bonding is caused and, on the contrary, when it exceeds 10sec, a bonding force becomes insufficient after bonding it to the film by pressure.
