    摘要: An imaging optical system smaller than conventional systems yet with well-corrected aberrations, comprises five lenses L1-L5 having refractive powers, in order from the object side: positive, negative, positive, positive, and, with an aperture at an endmost object-side position. In one embodiment, L1 is biconvex, L2's object-side surface is convex, L5's object-side surface is convex, and 1.0

    摘要: A laser beam machining apparatus capable of highly accurate machining at a high speed. A parallel link mechanism including a plurality of links is fixed to a frame and a workpiece holder having moving means is provided thereunder. The links of the parallel link mechanism connect a movable member with a stationary member, and the movable member is moved with respect to the stationary member by the extending/retracting operation of the links. A laser head serving as a machining head is attached to the movable member. A supply line includes a laser transmitting optical fiber, pipes for supplying water, assist gas, etc., and an electrical signal line. A laser beam LB outputted from the laser head performs machining on a workpiece W on the workpiece holder. The supply line passes through a through hole formed inside link joint portions on the stationary member. Hollow motors for driving the links of the parallel link mechanism are mounted on the stationary member.

    摘要: A printed wiring board is made of first and second substrates superimposed on each other. The first and second substrates respectively include a core layer made of resin containing carbon fibers. The second substrate has the outline different from that of the first substrate. A stepped surface is defined on the front surface at least of the first substrate. Electrodes can be formed on the stepped surface as well as on the back surface of the first substrate and the front surface of the second substrate. This structure enables detection of an electric signal from the stepped surface. A further flexibility can thus be achieved in locating electrodes as compared with a conventional printed wiring board having uniform substrates simply superimposed on each other. This results in an expanded use or purpose for a printed wiring board.

    摘要: A gear mechanism in which the backlash between bevel gears can be easily adjusted is provided. The gear mechanism has first and second bevel gears which engage with each other; a supporting member, including first and second threaded portions, for the first and second bevel gears, and first and second bearings for rotatably supporting the first and second bevel gears on the supporting member. The first and second bearing include cylindrical members with threaded portions for engagement with the first and second threaded portions of the supporting member.
