Title: Reinforcing metallic pipe for image transmitting optical fiber bundle
Inventor: OUCHI TERUO
IPC: G02B6/44
Filed: 1985-04-22
Abstract: PURPOSE:To reduce the crosstalk of light transmitted through a single fiber by making metallic pipe larger in internal diameter where the metallic pipe is fixed to an in-cavity insertion part or ocular part than at the tip side where an end part of a fiber bundle is fitted. CONSTITUTION:The end part of the image transmitting optical fiber 5 is fixed in a through hole 3 so that its end surface 5a is in focus on the focus position of an objective system 6. The end part is fixed normally by clamping the metallic pipe 4 with a screw 8 screwed in a metallic tip fittings 2, but the internal diameter D2 of the metallic pipe 4 where the screw 8 is clamped is larger than the internal diameter D1 of the part where the end part of the fiber bundle 5 is fitted at the tip side and the length of the end part of the fiber bundle 5 with an adhesive corresponds to distance L from the end surface 5a, so when the metallic pipe 4 is fixed by clamping the screw 8, a gap is formed between the metallic pipe 4 and fiber bundle 5, so no strain is applied directly to the fiber bundle 5, thereby exerting no adverse influence.

Title: Magnetic field measuring instrument
Inventor: KIHARA HIROYUKI
IPC: G01R33/04
Filed: 1986-04-15
Abstract: PURPOSE:To simplify circuits by composing an exciting signal generating circuit of a rectangular wave pulse generating circuit and a detecting circuit of a timer circuit and a sample holding circuit. CONSTITUTION:A single-shot rectangular exciting signal Pk which has pulse width tau and a voltage Vd is supplied from the rectangular pulse generating circuit 20 to an exciting coil 1b wound around an annular magnetic core 1a. At this time, a signal Pk resonates at a frequency of 2tau cycles by a capacitor 3 connected in parallel to a detection coil 1c. The timer circuit 40a outputs a sample control signal Ps for tau/2 from the falling time t0 of the signal Pk to t1. The sample holding circuit 40b is supplied with the signal Ps at a terminal S from the time t0 to t1, so the voltage value of a detection signal Pb appears at a terminal O as a sample signal Pp. The signal Ps is not supplied to the terminal S after the time t1, so the voltage value Vp of the signal Pb at the time t1 is outputted continuously from the terminal O as the signal Pp. The voltage value Vp is proportional to the intensity Hs of an external magnetic field, so the intensity Hs of the external magnetic field is measured by measuring the voltage value Vp of the signal Pp after the time t1.
