摘要:
An autofocus device including: an optical source; an optical unit that allows emitted light from the optical source and object light from a measurement target to pass through the same optical path, the optical unit being arranged between the optical source and the measurement target; and a detection unit that performs focus detection by using the object light passed through the optical unit. The optical unit includes: a tube lens that forms the emitted light into parallel light; an image forming unit that forms a continuous line image on a surface of the measurement target; and a rotation unit that rotates the continuous line.

An autofocus device includes an objective lens, an observation optical system, a driving mechanism that displaces the objective lens in an optical axis direction thereof, an illumination-optical-system optical path used to illuminate a measurement surface of a measurement object through the objective lens with light, and a pattern-projection-optical-system optical path. An electronic control shutter, a pattern projection plate having a predetermined pattern formed thereon, and a projection lens are provided in the pattern-projection-optical-system optical path.

A multilayer inductor having a uniformly improved direct current superposition property and an increased inductance value is disclosed. The multilayer inductor contains a laminate of a plurality of first insulating layers and a plurality of conductive layers, and the conductive layers and through hole conductors are connected to form a helical coil in the laminate. A second insulating layer which has a magnetic permeability lower than those of the first insulating layers is disposed such that it crosses an inner magnetic path of the helical coil, and a margin of the second insulating layer overlaps with the conductive layer in the stacking direction and is in contact with the conductive layer in the overlap portion. The magnetic flux density in the laminate is likely to be highest in the overlap portion, and thus, the highest-density magnetic flux passes through the second insulating layer inevitably, whereby the direct current superposition property can be uniformly improved.

An optical measuring machine includes a screen having a reference line, a movable stage, a detector for detecting a displacement of the stage, the first and second image-forming units for forming optical image(s) of a target object mounted on the stage on the screen, and a storage for storing the optical image(s). The first image-forming unit includes an image pickup for picking up the optical image(s), an output unit for outputting the picked up optical image(s) in digital image data, and a projecting unit for projecting the optical image(s) on the screen in accordance with the image data output by the output unit. The storage stores the image data output by the output unit.

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 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 composite joystick switch has easy and positive operability. The joystick has a shaft and is provided with a plurality of switches operable by a user's fingers. A housing with a through-hole receives the joystick shaft and a plurality of second switches are provided around the through-hole outside or inside the housing. A guide plate is provided on the upper surface of the housing. A shell bearing supported in the housing receives a core bearing supported in the shell. Both are pivotally mounted in perpendicular directions. The joystick shaft extends through the guide slot in the shell bearing and is secured to the core bearing. A switch control is provided at a portion of the joystick shaft extending beyond the fulcrum of the joystick to turn on and off second switches. A seat is provided opposite to the switch control. A spring is provided around the joystick shaft between the seat and switch control to automatically return to its neutral position the joystick once tilted.

Resin having a susceptibility to electrostatic charge which is opposite in polarity to the susceptibility to electrostatic charge of a filter sheet or member forming a filter element is impregnated into the filter member. For example, when the filter member is composed of polyester of 50-70 weight percentage and glass fiber of 5-25 weight percentage as well as pulp of 15-35 weight percentage, resin composed of phenol resin of 5-20 weight percentage and melamine resin of 80-95 weight percentage is impregnated into the filter member so that the susceptibility to electrostatic charge of the filter member can be neutralized. Thus, static electricity generated by friction between the filter element and fuel flowing therethrough can be controlled.
