Title: Automatic measuring method for coupling length of polarization plane maintaining optical fiber
Inventor: KUMAGAI TATSUYA
IPC: G01M11/00
Filed: 1986-01-06
Abstract: PURPOSE:To execute an automatic measurement with a high accuracy by a short size sample, extending from that of a short coupling length to that of a long coupling length, by measuring automatically a coupling length of a polarization plane maintaining optical fiber, from a periodic variation against a wavelength of a ratio of a difference and the sum of a light intensity in two directions. CONSTITUTION:A light beam which has brought a white light from a light source 1, to a spectral processing to a monochromatic light of an optional wavelength by a spectroscope 2 is made incident on a polarization plane maintaining optical fiber 5, as a linearly polarized light having a polarization plane of an azimuth of 45 degrees against an intrinsic polarization axis of the fiber 5 by a polarizer 3. Subsequently, this light beam is separated into two intrinsic polarization modes, and propagated by varying a polarization state. In this state, an emitted light of the fiber 5 transmits through an analyzer 6 which has been set to an azimuth of 45 degrees against the intrinsic polarization axis and inputs its transmission light intensity to a computer 10 through a multi-mode optical fiber 7, and a Ge-APD8. Also, this operation is repeated with respect to each wavelength, and subsequently, the analyzer 6 is rotated by 90 degrees and in the same way as said operation, a light intensity in each wavelength is measured. In this way, a coupling length of the fiber 5 is measured automatically from a periodic variation against the wavelength, of a ratio of a difference and the sum of a light intensity in two directions.

IPC: F02P17/00
Filed: 1990-01-08
Abstract: PURPOSE:To improve reliability of misfire warning by judging whether a misfire is true or not and forbidding warning of a misfire cylinder when the judgement is negative depending upon whether variation of exhaust component concentration corresponds to generation of misfire at a plural number of cylinders or not. CONSTITUTION:Crank angle speed of an internal combustion engine is detected by a means A, and a misfired cylinder is detected by a means B based on the above detected result.

Abstract: The invention relates to a process for relaxing lateral stresses at the end of shaping by compacting of a block constituted by an aggregate and a binder (such as a carbon-containing paste), to which is applied a main monoaxial stress in a rigid mold having a bottom and four side walls. According to the process, at the end of compacting and along the compacting axis, there is maintained a residual stress of between 50 and 2000 kilopascals, and preferably between 100 and 500 kilopascals. At least two of the side walls of the mold are then moved apart by a few millimeters, followed by the elimination of the main stress and the extraction of the molded block. The residual stress is maintained for a period of between 1 and 20 seconds following the moving apart of the walls.
