Title: Vibration resistant joint structure for construction member
Inventor: NAKAGAWA MASAYOSHI
IPC: E04B1/61
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To provide vibration resistant joint structure preventing a crack or the like of peripheral concrete associated with the elongation of an anchor member for fixing a male-type fit-in part even in the case of stress being applied thereto by vibration so as to be able to maintain the stable joint state of each construction member. SOLUTION: An anchor member 3 of a male-type fit-in part which is a joint part of both construction members 2 is wound with cushioning material 6 to cut off adhesion between the anchor member 3 and peripheral concrete 13. Accordingly, in case of stress (tensile force) acting upon the male-type fit-in part 4 due to vibration caused by an earthquake or the like, the anchor member 3 of the male-type fit-in part 4 can be freely deformed (moved). Since there is no adhesion to the peripheral concrete 13 when the anchor member 3 is about to be elongated, the anchor member 3 can be freely deformed (moved) without having adverse effect such as a crack to the peripheral concrete 13 so as to be able to maintain the joint part of both construction members 2 in a stable state even in the case of occurrence of an earthquake or the like.

Title: Method for winding tape of optical fibers
Inventor: KOIDE TOSHIO
IPC: G02B6/08
Filed: 1992-11-11
Abstract: PURPOSE:To prevent the tape of optical fibers from overlapping and falling with sufficient reliability and to prevent disorder of winding due to the overlapping and falling and to make possible winding the tapes on themselves in a stable state by setting the intervals of the tape of optical fibers within a specific range. CONSTITUTION:The tape of optical fibers are wound at intervals which are 1/4-1/100 as large as the width of the tape. Namely, when the winding pitch P of the tape of optical fibers is a+aX(1/4-1/100), the intervals (d) (interval of winding) between the tape of optical fibers on a take-up reel are aX(1/4-1/100). Even if the intervals (d) of winding decreases owing to deviation in the winding pitch, the deviation is never <=aX1/100. Therefore, a side end of a tape of optical fibers to be wound never overlaps with a side end of a tape of optical fibers which are already wound nearby.

Title: Demodulation method for phase modulation wave
Inventor: NOJIMA TAKAFUMI
IPC: H04L27/22
Filed: 1994-12-27
Abstract: PURPOSE: To allow a demodulator side to track automatically the frequency fluctuation of a phase modulation wave without transmission of the phase modulation wave with a pilot signal or the like added thereto. CONSTITUTION: A modulation phase ≃1 of an input signal being a phase modulation wave is detected based on orthogonal conversion outputs x1 , y1 . A CPU 5 detects a phase error 68 based on the modulation phase ≃1 and converts it into a frequency deviation Δf. External frequency information (f) is corrected by the frequency deviation Δf of the input signal obtained in this way and a read address of a reference signal table ROM 6 is calculated by using the external frequency information (f) after the correction. Thus, the frequency of the reference signal fed to modulation multipliers 2a, 2b is corrected in following to the frequency fluctuation of the input signal. In this case, the transmission band width is not spread.
