Abstract: PURPOSE:To surely and smoothly send an optical fiber into a pipe without damaging the fiber by providing a spool to be rotated in accordance with the transfer condition of the optical fiber in the pipe at the rear of a vibration proofing guide provided close to the pipe end. CONSTITUTION:The optical fiber 6 is veered out from the spool 13, and moved successively through the spool 13, a holding guide 12, a detector 11, the vibration proofing guide 10, a pipe inlet end 7, the rolled pipe P, and the pipe terminal end 8 by the vibration of the roll R. The fiber is thus charged into the whole roll after a specified time. When the upper detector 11A is turned on and the excessive tension of the optical fiber 6 is detected, the signal is sent to a driving motor 14, hence the rotational speed of the spool is increased, and the supply speed of the optical fiber 6 is increased. Meanwhile, when the excessive sagging of the optical fiber 6 is detected by the lower detector 11B, the motor is controlled in the same way, and the supply speed of the optical fiber 6 is reduced. The abnormal transfer condition of the optical fiber is immediately detected in this way and corrected, and the transfer is normalized.

Title: Torque sensor
Inventor: ISHIKAWA TAKASHI
IPC: B62D5/04
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable torque sensor by detecting a contact failure in a contact part between a detecting coil to detect torque and another circuit element. SOLUTION: When a contact failure occurs between a detecting coil 13 (14) and a resistance R1 (R2) and contact resistance is increased, apparent pure resistance is increased in the detecting coil 13 (14), its impedance is increased, and an out-of-phase signal in comparison with the phase of a signal of normal time is outputted from an operational amplifier OP2. The A.C. current of an oscillating part 21 is impressed on the input-side (-) terminal of a comparator CP2, and the output of an operational amplifier OP1 is inputted to the input-side (+) terminal. A phase deviation occurs between the output waveform of the CP2 and the output waveform of the CP1, and the output synthetic waveform of the CP1 and CP2 becomes a rectangular waveform of width corresponding to the phase deviation. As a result, a transistor TR is turned on to inhibit the output of the operational amplifier OP2.

Title: Synchronization control system
Inventor: NAKASE NAOKI
IPC: H04L7/033
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To prevent the situation that it takes time for phase comparison of a DPLL circuit, pull-in time is not converged within the preamble of a data string and the head part of data causes a code error. SOLUTION: This system is provided with a phase correction circuit 50 for detecting the phase deviation of reset input signals synchronized with a reference clock and reception data and delaying the reception data so as to correct the phase deviation. By correcting the phase deviation due to asynchronization before re-timing by the DPLL circuit 12, the pull-in time is shortened. Thus, since the pull-in time is converged within the preamble of the data string, the head part of the data does not cause the code error.

IPC: G02B27/46
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To enable the switching of the depth of field to be performed by using a spatial frequency conversion means by constituting this means in such a manner that the switching of a state of executing the conversion of a spatial frequency characteristic and a state of not executing the conversion can be switched. SOLUTION: A pupil modulation element 3 comprises an element 4 and an element 5. The element 4 and the element 5 are arranged symmetrically with an aperture stop 2 in an optical system L1. The element 5 is so constituted that the element can be rotated around the optical axis O of the optical element L1 (a). The element 5 is rotated 180 deg. around the optical axis O and is so arranged as to negate the conversion quantity of the spatial frequency characteristic of the element 4 and the element 5 (b). As a result, the switching to the state of converting the spatial frequency characteristic and the state of not executing the conversion is made possible.  When the spatial frequency characteristic is converted, the spatial frequency characteristic deteriorated by the pupil modulation element 3 is restored by a signal processing means and observation is executed at the enlarged depth of field. When the conversion is not executed, the observation is executed at the ordinary depth of field without using the signal processing means.
