Title: Steel pipe outer peripheral length measuring method and device
Inventor: MAEDA KOZO
IPC: G01B17/00
Filed: 1990-04-28
Abstract: PURPOSE:To accurately measure the outer peripheral length of a steel pipe by giving impact to a point on the outer peripheral surface of the steel pipe and by detecting the surface wave generated in the steel pipe on another point on the plane orthogonally intersecting the axis of the steel pipe on the outer peripheral surface of the steel pipe including the former point. CONSTITUTION:An impact giving device 9 and ultra sonic detector 10 are provided on a point X on a plane orthogonally intersecting the axis of a steel pipe 1 on the outer peripheral surface of the large diameter steel pipe 1 to be measured an on a point Y separated by the given distance l from the point X respectively. When impact is given by the impact giving device 9, the surface wave, generated due to acoustic emission, radially spreads in the steel pipe 1. At this moment, a signal S1 spreads clockwise by arc distance l in a surface wave spreading path Wa and is detected by a detector 10 after there is a lapse of time T1 after the giving of impact. In a surface wave spreading path Wc, a signal S3 goes around the steel pipe 1 clockwise and spreads by the distance and is detected by the detector 10 after there is a lapse of time T3. A calculator 11 calculates the time (T3 - T1) to determine the outer peripheral length L of the steel pipe 1 from the characteristic spreading velocity V of the prepared surface wave using the equation, L = V(T3 - T1).

Abstract: PURPOSE: To control both of low-speed and high-speed fuel metering systems accurately by providing two diaphragms in a single vacuum chamber of a fuel metering section.  
     CONSTITUTION: Two diaphragms 21, 31 are provided in a single vacuum-operated means 20. A needle 22 is fixed to one diaphragm 21 for defining a fuel metering section 24 between the needle 22 and an orifice 23. Similarly, a needle 32 is fixed to the other diaphragm 31 for defining a fuel metering section 34 between the needle 32 and an orifice 33. Further, a two-position solenoid valve 50 is provided for controlling a passage 61 and an air inlet passage 62 in response to a signal from an electronic circuit 70.

Title: Optical fiber coil and manufacture thereof
Inventor: OGURA KUNIO
IPC: G01C19/72
Filed: 1994-04-28
Abstract: PURPOSE:To provide a method for manufacturing an optical fiber coil in which dispersion of polarization is suppressed and prevented from increasing. CONSTITUTION:An optical coated fiber 1 wound around a bobbin 5 is wound into an optical fiber coil 4 by means of a traverse having a pitch different, by a predetermined amount or more, from the dimension of outline of the optical coated fiber 1. Since the optical coated fiber 1 is wound randomly, it is subjected to the side pressure not from a predetermined longitudinal direction of the optical fiber but from a random direction. Since the cross-section of an optical fiber is subjected to the side pressure from a random direction, the dispersion of polarization is not increased and thereby it causes no trouble in high speed communication. The optical fiber coil also causes no problem when it is used as an optical sensor.
