    摘要: The optical device comprises a first substrate 10 having a control circuit formed on; optical waveguide layer 40 formed above the first substrate and having a refractive index changed by electro-optic effect; and second substrates 14a, 14b having prism electrodes 18 for applying voltages to the optical waveguide layer. The control circuit and the prism electrodes are electrically connected to each other via columnar conductors 20. Even in a case where thermal expansion coefficients of the control substrate and of the light deflection substrates are very different from each other, the pins are flexed corresponding to eternal forces, whereby junction is protected from being damaged in the joining processing. Thus, the optical switch can be highly reliable.

    摘要: A tractor with a backhoe is disclosed. The backhoe is mounted to a rear portion of the tractor. The backhoe has a boom, an arm pivotally supported to a leading end of the boom, a bucket pivotally supported to a leading end of the arm, a boom cylinder for operating the boom, an arm cylinder for operating the arm and a bucket cylinder for operating the bucket. The tractor includes a frame attached to a rear portion of the tractor, a swing bracket supported to a rear portion of the frame to be pivotable about a vertical axis, a control valve unit having control valves for controlling the boom cylinder, the arm cylinder and the bucket cylinder and a hose unit for feeding pressure oil from the control valve unit to the boom cylinder, the arm cylinder and the bucket cylinder. The wing bracket includes a first opening open to the front side and a second opening open to the rear side. The control valve unit is disposed, in its plan view, on an extension line of the first opening and the second opening. The hose unit extends substantially linearly from the control valve unit through the first opening to the second opening.
