    • In an optical filter module and an optical amplification apparatus for a wavelength division multiplex (WDM light), the respective wavelength intervals of the plural passing center wavelengths and the filter characteristics in the vicinities of the respective center wavelengths can be set independently, whereby the BPF1 is provided with different passing center wavelengths .lambda.1, .lambda.2 . . . .lambda.n and different filter characteristics. And, when the WDM signal light including wavelengths .lambda.1, .lambda.2 . . . .lambda.n is inputted into the port 2-1a, the .lambda.k (k=1,2 . . . n) component is transmitted by the corresponding BPF1-k, and the transmitted light is multiplexed sequentially and outputted from the port 2-nb and the other wavelength components (noise light components) are reflected by all of the BPFs and outputted from the port 2-nc. When the WDM signal light including wavelengths except for .lambda.1, .lambda.2 . . . .lambda.n is inputted into the port 2-nc, the component of the wavelength .lambda.n (noise light component) is outputted from the port 2-1d and the other wavelength components are outputted from the port 2-1a. And, the optical coupler 6 monitors the output light of the BPF 1 to perceive the levels of the respective wavelength components in the WDM signal light.

    • A multijoint manipulator apparatus includes a tubular-member, linear-motion-transmission-members, a drive-unit, a position-detector, a tension-detector, an operation-unit, and a movement-degree-calculation-unit. The linear-members are inserted in the tubular-member, one end and the other end of each of the linear-members being fixed to the vicinity of a joint of the tubular-member and the drive-unit, respectively. The drive-unit moves the linear-members. The position-detector and the tension-detector detect positions and tension of the linear-members, respectively. A desired position/posture of a point of interest is input to the operation-unit. The calculation-unit calculates a current position/posture of the point, a weighting factor serving to give priority to and move the linear-members the tension of which is relatively low among the linear-members, and movement degrees of the linear-members to move the point to the desired position/posture, and causes the drive-unit to pull the linear-members.

    • A method of manufacturing a retainer for a roller bearing made of a metal plate and has a tubular main portion, pockets formed in the main portion intermittently concerning a circumferential direction and capable of retaining rollers rollably, and an outwardly oriented flange-like collar portion. An annular intermediate material is formed by die cutting the metal plate, and after a second intermediate material is formed by forming through holes in the intermediate material intermittently, a portion of the second intermediate material excluding a radially outer end portion is plastically deformed into a tubular shape. The portion plastically deformed tubular shape is formed as the main portion, a portion corresponding to the radially outer end portion of the second intermediate material is formed as the collar portion or a collar portion element for forming the collar portion, and portions corresponding to the through holes are formed as the pockets.
