Upon zooming from the wide-angle end to the telephoto end, at least the first lens group and the aperture stop remain fixed in position, the second and third lens groups move in the optical axis direction, and the separation between each of the lens groups and the aperture stop changes. Upon focusing from a focusing-on-infinity state to a close-range-focusing state, the fourth lens group moves in the optical axis direction, with satisfaction of the following: −0.36

摘要： A zoom lens consists of, in order from its object side, a first lens group of negative refracting power, and a second lens group of positive refractive power wherein zooming from a wide-angle end to a telephoto end is implemented by changing a distance between the respective lens groups. The first lens group consists of, in order from its object side, a front unit of negative refracting power, and a rear unit of negative refracting power. The front unit consists of, in order from its object side, a first lens that has negative refracting power and meniscus shape, and includes an aspheric surface, and a second lens that is smaller than the first lens in terms of an absolute value of refracting power, and includes an aspheric surface. The rear unit consists of, in order from its object side, a third lens of negative refracting power, a fourth lens of negative refracting power, and a fifth lens that has positive refracting power and is convex on its object side, and upon zooming from infinity to point-blank range, the rear unit moves in such a way as to draw nearer to the object side as the space between the front unit and the rear unit becomes narrow.

摘要： A thermal enhanced structure comprising a packaged electronic device and a heat sink that is removably attached thereto. The thermal enhanced structure includes a plastic ball grid array (PGBA) with an electronic chip, a plastic mold cover, and a heat spreader with a plurality of spaced apart securing studs positioned and caulked at a periphery edge thereof. The mold cover, the heat spreader and studs are molded and embedded with one another to form a single unit with improved torque strength and heat dissipation. The single molded unit and the plastic ball grid array are secured together by an adhesive material. Then the heat sink can be easily and removably attached to the molded single unit by fastening elements to the molded studs, thereby allowing more efficient controllable forces or pressures to be applied as the mechanical fastening elements are removably attached to the molded studs to thereby prevent stress and damage to the PBGA package.

摘要： Disclosed is a pattern inspection apparatus which easily and highly accurately detects a profile error (deviation) of at least one pattern having a cross section with projections and recesses. The inspection apparatus for the pattern 32 is for detecting the profile error of the pattern having a cross section with a projection and a recess. This inspection apparatus includes a plate 30 on which a pattern is mounted, light sources 40, 42 and 44 which can change angles of illuminating light emitted onto the pattern, within a range of 15 to 75 degrees with reference to the top surface of the pattern, and photodetectors 52 and 54 which can receive reflected light from the pattern at an angle within a range of 15 to 75 degrees with reference to the top surface of the pattern. The inspection apparatus is characterized by that the profile error of the pattern is detected based on an amount of the reflected light from an edge between the top surface and the side surface of each of the patterns.

The stator may be composed of two magnets fixedly mounted on said casing and located on both ends of said rotary shaft, each magnet including quartered, arched sub-magnets, the sub-magnets having magnetic poles of the same polarities located on an outer circumference of the stator which polarities are different from those of said ferrite magnets. The rotor may be located at the center of said casing and operatively connected to said rotary shaft, the rotor being configured with vane members located at both ends of the rotary shaft through a cylindrical member disposed therebetween and being made rotatable interiorly of said stator segmented sub-magnets.
