Abstract: A control apparatus controls a vehicular air-conditioning system to control a fuel-combustion heater for producing combustion heat to heat a heating medium in a heating medium circuit which heats air flowing through a duct having air outlets openable into a passenger compartment, through heat exchange between the heating medium and the air with a heat exchanger disposed in the duct. The control apparatus has a shutdown controller for temporarily shutting down the fuel-combustion heater and an extinguishing controller for extinguishing the fuel-combustion heater based on a signal from the shutdown controller. The shutdown controller includes a shutdown signal entering unit for entering a shutdown signal to temporarily shut down the fuel-combustion heater and a shutdown signal canceler for canceling the shutdown signal in response to a canceling signal entered to cancel the shutdown of the fuel-combustion heater within a predetermined period of time after the shutdown signal has been entered.

Abstract: An optical fiber is rolled by a swing motion of a swing guide roller in order to impart a predetermined twist to it effectively, and its polarization dispersion is suppressed equivalently as in a perfectly circular concentric optical fiber. A method of manufacturing such an optical fiber is also provided. As a swing guide roller swings, the optical fiber is rolled on its roller surface, so that a clockwise twist and a counterclockwise twist are imparted to the optical fiber alternately. At this time, the optical fiber is fitted in a V-shaped narrow groove formed at the central portion of the roller surface of a next-stage first stationary guide roller provided just beside the swing guide roller. Rolling of the optical fiber on the roller surface of the first stationary guide roller is suppressed, thereby helping smooth rolling of the optical fiber on the roller surface of the swing guide roller.
