Abstract: PROBLEM TO BE SOLVED: To obtain a single mode fiber preform with little Rayleigh's scattering loss by using a tube having a thermal conductivity lower than a quartz tube for a first preform as a quartz tube for overclad in an optical fiber preform comprising a core and clads enclosing the core.  
     SOLUTION: In forming a final fiber preform 28 by overcladding using a quartz tube for overcladding a first preform on which a deposition layer 10 comprising a core layer and a clad layer is formed by an internal chemical deposition using a quartz tube for the first preform, a synthetic quartz tube is used as the first quartz tube 2 for the first preform and the synthetic quartz tube is used for a second quartz tube 20 for overcladding. The synthetic quartz tube has a thermal conductivity lower than the first quartz tube and a hydroxy group concentration less than 5 ppm. In producing an optical preform, a plurality of the quartz tubes 20 for overcladding are sequentially overcladded and a thermal conductivity of each quartz tube is lowered toward periphery.

Abstract: PROBLEM TO BE SOLVED: To provide a low-cost impact sensor having a permanent magnet capable of staying long and stably at a position closing a contact part of a reed switch, having a simple structure allowing the size of a housing to be reduced in the direction of collision, and capable of enhancing reliability. SOLUTION: This impact sensor uses a volute spring 24 (its size can be arbitrarily changed in the direction of collision) having winding diameters varied in the axial direction and having a spring constant not constant but increasing correspondently to the amount of distortion. A front stopper 26 is used to stop the movement of the annular permanent magnet 23 by colliding with it. The stopper 26 is shaped to serve as one end face of a case 27 and allows one end part (large-diameter end part) of the spring 24 to abut thereon. When a large acceleration is exerted due to an impact, the movement of the permanent magnet 23 is smoothly slowed down, thereby decreasing an impact due to a collision with the stopper 26.
