Title: Synthesis of preform for optical fiber and method for adjusting conditions for synthesis
Inventor: HOSHINO SUMIO
IPC: C03B37/02
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To obtain a preform for an optical fiber decreased in the fluctuation of a specific refractive index difference (Δn) between a core and a clad in an axial direction and the fluctuation of an outside diameter ratio between the core and the clad in the axial direction by investigating the degree of the growth of the clad by measuring the height of the deposition surface of the clad and feeding back the degree to conditions for synthesis. SOLUTION: A burner 3 for the core for synthesizing a core part 4 and a burner 2 for the clad for synthesizing a clad part 5 are arranged. The glass particulates synthesized by supplying glass raw materials to the respective burners are deposited on a rotating starting rod 1, by which the preform for the optical fiber is synthesized. The distance L in the axial direction from the front end of the core of the deposition surface at which the radius (r) of the part to constitute the clad 5 attains an arbitrary certain value is measured. The measured value L is so controlled as to attain always the specified value by adjusting the flow rate of the glass raw materials or gaseous hydrogen to be supplied to the clad burner 2 from the result of the measurement.

Filed: 1985-09-26
Abstract: PURPOSE:To always obtain the optimum spacing and simultaneously to obtain a disk having excellent durability and high reliability by forming a lubricating film when the surface of an alumite film having pores packed with a magnetic substance is polished. CONSTITUTION:Al is anodized to generate innumerable fine pores in the alumite film and a magnetic substance is packed in the fine pores by electrodeposition and/or electroless deposition. Then the alumite film is polished to specified thickness and the surface is finished in the desired state. At this time, a thin oil film is formed on the polished surface. The oil film is not removed and is positively converted into a lubricating film. Since the lubricating film is formed simultaneously with the smoothing of the surface, the process can be remarkably simplified, the adhesion of the lubricating film formed by the chemical reaction is excellent and a thin film can be uniformly formed.

The comparator 7 outputs the status 8 which is '1' indicating the chirp signal when the output of the multiplier 6 is larger that the constant value, but '0' indicating a fixed signal when the output of the multiplier is nearly equal. Consequently, the in-pulse frequency mode can be detected in one-pulse measurement.

Title: Thermal element
Inventor: YAMAZAKI KIICHI
IPC: F15B21/06
Filed: 1986-09-10
Abstract: PURPOSE:To ensure the sealing between expansive substance and gas by removing a sliding part from a thermal element. CONSTITUTION:A pressure chamber 8 is formed, inside a case 1, with the case 1 serving as a temperature sensing element and an inversion plate 7 on whose center part a rod 6 is integrated. A wax 3 and air are sealed in the pressure chamber 8 so that they may occupy appropriate ratios to the volume thereof. When the temperature is low and the wax shrinks, the inversion plate 7 is supported on the edge of the case 1 in a recessed condition, when looked at from the outside of the case 1, and seals the wax 3 and the air therein. The increase in the pressure in the pressure chamber 8 causes the inversion and elastic deformation of the inversion plate 7, and then the decrease in the pressure if occurs thereafter, makes it invert again and restore its original state. This constitution, thus, enables the seal between an expansive substance and air.
