Title: Light interference sensor, light branch coupler and apparatus for fabricating light interference sensor
Inventor: OBO SHIGERU
IPC: G01C19/72
Filed: 1990-06-04
Abstract: PURPOSE:To obtain an interference sensor with stable characteristics by providing a light branch coupler wherein a light phase difference between transmission light and branch light has been adjusted to a predetermined value as an optical element of an optical system. CONSTITUTION:A signal processing circuit 50 receives an interference signal from a light detector 40 which varies sine-functionally with respect to a phase difference phis and outputs linear signal voltage with respect to the phase difference phis by inverse sine functional calculation. When a light amount from a laser light source changes, an amount of received light of the light detector 40 immediately varies. On the other hand, there may be a fluctuation in the light amount in an interference sensor employing an optical fiber due to a temperature of coupling efficiency between the light source and the optical fiber or due to a change with time, etc. Therefore, such a problem occurs that a proportional coefficient of output voltage of the signal processing circuit 50 and the input phase difference phis, in other words a voltage scale, varies due to an amount of incident light of the light detector 40. Thus a second light branch coupler 60 and a second light detector 41 are additionally provided. Therefore, as a result, output light from a second terminal 62 of the second light branch coupler is also maintained at a constant light amount.

Title: Double twisting spinning frame
Inventor: ANAHARA AKIJI
IPC: D01H7/86
Filed: 1984-07-14
Abstract: PURPOSE:To prevent the increase in the transport resistance of a yarn at the bent point, and prevent the excessive yarn tension, by imparting a false twisting to the yarn in ballooning process to the same direction as the real twisting applied by the rotation of the spindle. CONSTITUTION:A false twisting of the same direction as that of the real twisting is applied to the yarn Y of the ballooning stage by the action of the roller 52 placed near the turning point of the yarn. The collectability and the strength of the yarn can be improved by this process. Since the yarn Y is actively delivered upward by the roller 52, the transport resistance of the yarn Y at the bent point can be decreased. The end breakage is decreased, the productivity is improved, and the problems such as the complicate structure of the apparatus, large apparatus size, troublesome maintenance, etc. are avoided.
