    摘要： A bellows (2) of a dust boot (1, 30) having large diameter parts (3) and small diameter parts (4) disposed alternately covers a piston rod (R) projecting from a cylinder (C). A bump stopper (B) fixed to the cylinder (C) projects into the bellows (2) as a projecting portion. The bellows (2) comprises a first section (M) which passes a projecting end of the projecting portion according to the elongation and contraction of the piston rod (R) and a second section (L) located therebelow. By making the small diameter parts in the second section (L) have a smaller inner diameter than the small diameter part located at a boundary between the first section (M) and the second section (L), the bellows (2) can be made slim without interfering with the bump stopper (B).

    摘要： A method of manufacturing an optical filter that can restrain the wavelength dependence of the gain of an optical amplifier. The input signal light power, output power of pump light source (8), and the output signal light power of an optical amplifier (4) are set to the power values used for optical communication systems, and the total power of the simulation input light of a plurality of wavelengths (.lambda.1, .lambda.2, . . . .lambda.n) from light sources (1a) and an input light (probe light) from light sources (1m) are set equal to the total power of the input signals of a plurality of wavelengths used in wavelength division multiplex transmission systems. In this condition, the input light are multiplexed and are launched into optical amplifier (4), and the amount of attenuation from light source (1m) to the input end (14) of optical amplifier (4) is variably adjusted so that the output power from optical amplifier (4) in correspondence to the probe light will be within the range determined by the maximum and minimum of the output power corresponding to the simulation input light to determine the attenuation amount corresponding to the wavelength of the probe light. The above operation is repeated upon varying the wavelength of the probe light, and loss spectrum of the optical filter is set to the loss spectrum of the attenuation amounts in one-to-one correspondence with the respective wavelengths.
