    • The present invention proposes an optical wavelength division multiplexer device which has low through loss and low reflection loss, and also has high isolation. A filter member is made up from a filter base board upon which is formed a wavelength division filter 5, and is disposed so as to intersect an input and output optical waveguide 3 of rectilinear form part-way along it at an intersection angle .alpha.. When light which includes light of two different wavelengths .lambda..sub.1 and .lambda..sub.2 is incident through an incident light side of the input and output optical waveguide 3, the light of wavelength .lambda..sub.2 passes through the wavelength division filter 5 and is emitted through an emitted light side, while the light of wavelength .lambda..sub.1 is reflected by the wavelength division filter 5 in a direction separated from the input and output optical waveguide 3. A reflected light reception waveguide 1 is formed as rectilinear and is arranged in this reflection direction so as to receive the reflected light, with a gap being left between this reflected light reception waveguide 1 and the input and output optical waveguide 3, and the reflected light of wavelength .lambda..sub.1 is received into a reflected light reception end thereof and is emitted from a received light after end portion thereof. By providing this gap between the input and output optical waveguide 3 and the reflected light reception waveguide 1, increase of loss due to mutual action between the incident light and the reflected light is restrained.
    • 本发明提出了具有低通损耗和低反射损耗的光波分复用器装置,并且还具有高隔离度。 滤波器构件由滤波器基板构成,在滤波器基板上形成波长分离滤波器5,并且以与交叉角α成一直线的直线形式的输入和输出光波导3相交。 当包括两个不同波长λ1和λ2的光的光通过入射和输出光波导3的入射光侧入射时,波长λ2的光通过波长分割滤光器5并通过发射光发射 而波长λ1的光在与输入和输出光波导3分离的方向上被波分复用滤光器5反射。反射光接收波导1形成为直线形并沿该反射方向布置,以便 接收反射光,在反射光接收波导1和输入和输出光波导3之间留有间隙,波长λ1的反射光被接收到其反射光接收端并从接收光发射 后端部分。 通过在输入和输出光波导3和反射光接收波导1之间提供这种间隙,可以抑制由入射光和反射光之间的相互作用引起的损耗的增加。

    • A composite optical device has a first and second chips. The first chip has a substrate on which M pieces of optical waveguides for transmitting communication light, N pieces of optical waveguides for transmitting monitoring light and M-input/N-output star couplers are formed in an integrated form, and the second chip has a substrate on which N pieces of optical waveguides for transmitting communication light, N pieces of optical waveguides for transmitting monitoring light and N pieces of 2-input/2-output star couplers are formed in an integrated form. A first and second blocks holding optical fibers are joined respectively to the first and second chips. When the composite optical device in which the first and second blocks and the first and second chips are joined is incorporated into the optical communication system, a passive double star system is constructed. By using an MT connector instead of the first block and the first chip, a single star system can be rapidly constructed.

    • A pulley structure having a first rotating member that is rotatable around a first axis. A second rotating member is rotatable around the first axis and in at least partial axial coincidence with the first rotating member.

    • A working vehicle that uses the output of an internal combustion engine (30) as a working power and a traveling power includes an accelerator pedal (1) that increases a rotation speed of the engine (30) when depressed and a transmission (40) that shifts a rotation of the engine (30) and applies the shifted rotation to the traveling power. A speed ratio control device of the transmission (40) calculates a first target vehicle speed (Wne) according to the rotation speed of the engine (30), calculates a second target vehicle speed (Wu) according to a depression amount of the accelerator pedal (1), and controls the speed ratio of the transmission (40) on the basis of the smaller of these target vehicle speeds. As a result, a vehicle speed according to the depression amount of the traveling accelerator pedal (1) is obtained even when the internal combustion engine (30) rotates at high speed.
