An objective lens used for a microscope includes a lens(es), an iris diaphragm and a tubular body. The lens(es),which is provided in a manner facing an object, transmits light reflected from a measuring surface of the object. The iris diaphragm, which is provided behind the lens(es), changes an aperture diameter of a light-transmissive aperture of a light-transmissive surface that is substantially orthogonal to a main optical axis of the light transmitted through the lens(es). The tubular body, which is detachably mounted on a revolving nosepiece of a trunk that includes a zoom imaging lens(es) for forming an image from the light transmitted through the light-transmissive aperture, holds the lens(es) and the iris diaphragm.

A jet pump is provided for supplying fuel from a fuel tank into a sub-tank, which is accommodated in the fuel tank. The jet pump includes a welded portion adapted to being welded to an outer wall surface of a bottom portion of the sub-tank. A swirl portion defines therein a swirl chamber. A jet nozzle generates negative pressure by jetting swirl-flowing fuel passing through the swirl chamber so as to draw fuel from the fuel tank into the sub-tank. A pressure-receiving portion defines a clearance with respect to the swirl portion. The pressure-receiving portion extends from the welded portion in a direction to distant from the sub-tank. The pressure-receiving portion is applied with force toward the welded portion when the welded portion is welded to the sub-tank.

A molding attaching clip 30 includes a fixed portion 31 to be fixed in a groove 15 of a roof panel 10, a pair of elastically deformable wall portions 32 which are erected from the fixed portion 31, a pair of engaging portions 33 which are provided on the pair of wall portions 32, and an elastically deformable guide portion 36 which is projected from the fixed portion 31. A roof molding 20 includes a head portion 21 for covering the groove 15, and a projected portion 27 which is protruded from a back face of the head portion 21. The projected portion has a pair of locking portions 24 which are provided on both side faces thereof, and a receiving groove 26 which is formed in the projected portion 27. On occasion of engaging the roof molding 20 with the molding attaching clip 30, the roof molding 20 is positioned so that the pair of locking portions 24 can be engaged with the pair of engaging portions 33, by butting the receiving groove 26 against the guide portion 36.

A fuel feed apparatus, which is accommodated in a fuel tank, includes a sub-tank, a jet pump, and a covering member. The sub-tank includes a fuel inlet. The jet pump includes a jet nozzle, through which fuel is jetted to generate negative pressure, so that fuel in the fuel tank is drawn into the sub-tank through the fuel inlet. The covering member covers a gap formed between the jet nozzle and the fuel inlet. The covering member is opened on the bottom side of the gap. The covering member downwardly extends from the upper side to a gap-lower end position. The gap-lower end position is located on the upper side with respect to the center of the jet nozzle by a distance that is equal to or greater than 1 mm, and is equal to or less than 2 mm.

A CCD camera (27) images a work to generate its image data. An imaging optical system (24, 25, 26) focuses an image of the work on the CCD camera (27). A down-projection illumination source (31) includes at least one semiconductor light-emitting device for producing a down-projection illumination light to illuminate the work from above. An illuminating optical system (29) joins the illumination light from the down-projection illumination source (31) to the imaging optical system in order to lead the illumination light to the work via the imaging optical system. These optical components are mounted on a chassis (23) to construct an imaging probe (1), which is employed at any angle as a measuring probe of a three-dimensional tester.

The fixing apparatus for fixing a fuel filter in the present invention comprises a ring portion for fixing fuel filter body securely by utilizing contraction force of resin. The fixing apparatus is made of resin softened by heat. The resin fixing apparatus has ring portion for accommodating and fixing a fuel filter. The inside shape of the ring portion is formed similar and somewhat smaller than the outer cylindrical shape of the fuel filter body. When the ring portion is heated and the resin and resin become flexible, the fuel filter is allowed to be press fitted into the ring portion.

Disclosed is a laminated inductor that has good direct current superimposition characteristics, does not cause a variation in temperature characteristics, suppresses the occurrence of delamination, and can be stably manufactured. Also disclosed are a method for manufacturing the laminated inductor and a laminated choke coil. A laminated inductor (10) for use as a choke coil in a power supply circuit includes a rectangular parallelepiped-shaped laminated chip (1) and at least one pair of external electrodes (8) that are provided at the end of the laminated chip (1) and are conductively connected to the end of a coil. The laminated chip (1) includes a plurality of magnetic material layers (3) formed of an Ni—Zn—Cu ferrite, a plurality of conductive layers (2), which are laminated through the magnetic material layers (3) to constitute a coil, and at least one nonmagnetic layer (4) formed of a Ti—Ni—Cu—Mn—Zr—Ag-base dielectric material and formed in contact with a plurality of the magnetic material layers (3).
