Abstract: A protective tube attaching method, the protective tube protecting an electric wire of a wire harness, includes inserting the electric wire through a small diameter protective tube and a large diameter protective tube which covers and is shorter than the small diameter protective tube so as to be movable relatively thereto; positioning one end portion of the large diameter protective tube at one reference portion of the wire harness; moving the small diameter protective tube relatively to the large diameter protective tube positioned at the one reference portion, to thereby position the other end portion of the small diameter protective tube at the other reference portion of the wire harness; and fixing the other end portion of the large diameter protective tube in a state that the other end portion of the large diameter protective tube overlaps with an outer circumferential surface of the small diameter protective tube.

Abstract: A wiring structure of a door harness is wired so that the door harness is extended over a vehicle body and a door of a vehicle. A part of the door harness is passed through a first through hole in a door inner panel of the door and a second through hole in the door at a vicinity of the hinge. The door harness includes a door harness body and a grommet. The grommet includes a grommet body disposed in an opening/closing space of the door and a contained portion continuously provided to the grommet body and contained in an internal space of the door inner panel. A first engagement portion and a second engagement portion are provided at both ends of the contained portion. Both of a bending allowing portion and a restoring force generating portion are provided between the first and second engagement portions of the contained portion.

Abstract: A protective tube for protecting an electric wire of a wire harness, includes a small diameter protective tube, and a large diameter protective tube configured to cover the small diameter protective tube so as to be movable relatively thereto. A sectional shape perpendicular to its tube axis of at least one of the small diameter protective tube and the large diameter protective tube is formed into a non-circular shape which is obtained by pressing and deforming its circular cross-section by a predetermined amount or more, and the small diameter protective tube and the large diameter protective tube which are configured to be moved along a longitudinal direction thereof relatively to each other are frictionally engaged with each other.

Abstract: The semiconductor integrated circuit includes an inverting amplifier that generates an oscillation signal with an input connected to the first terminal and an output connected to the second terminal, the inverting amplifier fluctuating in gain in response to a gain control signal. The semiconductor integrated circuit includes a waveform shaping circuit that shapes a waveform of the oscillation signal and outputs a clock signal to a clock signal output terminal. The semiconductor integrated circuit includes an edge detecting circuit that detects an edge of the clock signal and outputs the gain control signal at a time of the edge.

Abstract: An improved steering system for a small-sized light-weight wheeled vehicle, such as an all-terrain vehicle being equipped with balloon tires, which comprises independent steering mechanisms adapted respectively to the steering operation of the front and rear wheels of the vehicle.
