Abstract: An optical sensor includes a radiation part that irradiates an object to be measured with laser light, an imaging part that receives laser light reflected by the object to be measured and captures an image of the object to be measured, a first driving part that moves the radiation part in a radiation direction of laser light to the object to be measured, and a second driving part that moves the imaging part in a reflection direction of laser light from the object to be measured and an orthogonal direction to the reflection direction.

Abstract: A pressure sensitive sensor includes: a first conductive member formed into a long shape, the first conductive member having conductivity and elasticity; a second conductive member internally including a long space to arrange the first conductive member, the second conductive member having conductivity and elasticity; and an insulating member having an insulating property and elasticity, the insulating member holding the first conductive member to separate the first conductive member from the second conductive member, the insulating member being movable relative to one or both of the first conductive member and the second conductive member.

Abstract: A weld joint has a weld portion for being welded and bonded to a rim portion around an opening of a resin fuel tank. The weld portion is made of a resin alloy material that is obtained by alloying EVOH or PA with a modified HDPE. A highly-weldable layer is provided in an extremity portion of the weld portion throughout an entire circumference of the weld portion. The highly-weldable layer is made of HDPE and/or a modified HDPE having good weldability to the resin fuel tank. An extremity end surface of the highly-weldable layer serves as a weld surface for welding the weld portion to the resin fuel tank.

Abstract: An annular positioning projection integrally has a body portion extending in a circular arc, one end portion projecting from one circumferential end of the body portion toward one raised portion and connected to a radial outer surface of the one raised portion, and the other end portion projecting from the other circumferential end of the body portion toward the other raised portion and connected to a radial outer surface of the other raised portion. An outer surface of one end portion thereof extends in a tangential direction with respect to one circumferential end of an outer surface of the body portion, and an outer surface of the other end portion extends in a tangential direction with respect to the other circumferential end of an outer surface of the body portion.

Abstract: A fuel hose for a fuel pipeline in an motor vehicle has a multilayer structure including a resin barrier layer having low permeability to fuel, an outer rubber layer laminated on an outer side of the barrier layer and an inner rubber layer laminated on an inner side of the barrier layer and defining an inner surface layer of the fuel hose. The multilayer structure is formed throughout an entire length of the fuel hose. A rubber hardness of the inner rubber layer is higher than a rubber hardness of the outer rubber layer.
