摘要： A fluid pressure reducing device having a core provided with a peripheral spiral groove and a pipe receiving the core. The portion of the pipe receiving the core is radially contracted so that the ridges of the spiral groove of the core intrude into the inner peripheral surface of the pipe, thereby to form a spiral passage between the pipe and the core. The pressure of a fluid is reduced as the latter flows through the spiral passage. This fluid pressure reducing device is easy to produce and permits an easy fine adjustment of the flow resistance.

摘要： After a metallic cylindrical tube is bulged to form a bellows with a circular cross section, this bellows is ovalized to form a bellows with an oval cross section. For this reason, an inexpensive round tube (cylindrical tube) can be used as the material for a bellows with an oval cross section and it is unnecessary to use an expensive oval tube. Accordingly, a bellows with an oval cross section can be produced at low cost.

摘要： Provided is a calibrating apparatus for an on-board camera of a vehicle, which apparatus allows completion of calibration process with a simple additional calibration, even when rejection has issued on the result of automatic calibration. Based upon a camera parameter obtained at the time of completion of adjustment by an automatic adjusting section, a confirmation marker indicating the position of coordinate of a calibration point is displayed in superposition with a camera-captured image. A manual adjusting section adjusts the camera parameter, based on an amount of displacement of the coordinate of the calibration point corresponding to an amount of movement of the confirmation marker moved in response to input of adjustment instruction. In response to input of a determination instruction, a camera parameter setting section sets an undetermined camera parameter at the time of completion of the most recent adjustment by the automatic adjusting section and the manual adjusting section, as the camera parameter.
