摘要:
There is provided a functional panel that can be joined and disassembled with ease by solving problems with a functional panel including electrical conductors integrally molded therewith, causing occurrence of cracking on the surface thereof, or cracking of a molded unit around the periphery of the electrical conductor, thereby rendering the electrical conductor susceptible to a break when a flexural load, an impact load, and so forth, acts on the functional panel. The functional panel comprises a main body of a panel member, an electrical conductor coated with a semi-cured resin having heat resistance and insulation properties, and a reinforcing fiber having a continuous filament, for fixing the electrical conductor to the main body of the panel member to thereby provide enhancement, and the functional panel is formed by exposing one end, and the other end of the electrical conductor from respective end faces of the panel member formed by integral molding.

The present invention relates to sliding parts, precision parts and timepieces and electronic equipment using those parts. Sliding parts are composed by a resin in which the degree of orientation of a fibrous filler is higher at the portion serving as the sliding surface than inside the sliding part, and the fibrous filler is oriented along the sliding surface on the sliding surface. Alternatively, precision parts are composed by a resin to which has been added carbon fibers for which a carbon compound is thermally decomposed to carbon in the vapor phase and simultaneously grown directly into fibers simultaneous to this thermal decomposition. Moreover, timepieces and electronic equipment are composed by these sliding parts or these precision parts.

A chip transfer apparatus includes a first carrier for feeding chips and a second carrier for carrying works on it. The transfer apparatus also includes a transfer engine including two or more coaxial revolvers, which can revolve coaxially with each other. Each of the coaxial revolvers includes an end-effector for receiving a chip from the first carrier and transferring the received chip onto a work on the second carrier. The end-effectors of the coaxial revolvers are arranged in a circle coaxial with the revolvers. The end-effectors sequentially receive chips from the first carrier at substantially zero speed relative to the first carrier and transfer the received chips onto works on the second carrier at substantially zero speed relative to the second carrier. While the end-effectors are revolving, they undergo periodic speed change control for timing adjustment and speed adjustment for the chip reception and transfer.

A laser machining apparatus capable of accurately projecting mask patterns onto a work piece and superior in machining accuracy. An auto-focusing unit is provided. The auto-focusing unit includes a television camera for observing alignment marks formed on the surface of the work piece so as to be able to measure the focal length of a projection lens. A main-scanning direction expansion/contraction ratio Ex of the work piece to its design value and a sub-scanning direction expansion/contraction ratio Ey of the work piece to its design value are obtained. The imaging magnification M of the projection lens is corrected to compensate the expansion/contraction ratio Ex. The moving speed of a mask and/or the moving speed of the work piece are corrected in consideration of the imaging magnification M of the projection lens so as to compensate the expansion/contraction ratio Ey.
摘要:
A printed circuit board manufacturing method by which the manufacturing time can be shortened and the manufacturing cost can be reduced. A printed circuit board has an insulating layer on its surface. Positions (first positions) of the printed circuit board where lands are disposed are irradiated with a CO2 laser beam (first laser beam) so as to form holes with a depth h from the surface. The printed circuit board is then scanned with an excimer laser beam (second laser beam) through a mask. The beam shape of the excimer laser beam is rectangular. Thus, holes reaching the lands are formed in the positions where the lands are disposed, and grooves for forming lines are formed (second positions). In this case, the holes reaching the lands may be formed by the CO2 laser beam.

Fluid food materials which solidify when cooled are quantitatively supplied successively at a certain thickness in a plate form on cooling and carrying sides; of two cooling and carrying devices, cooled while being carried to form two monolayer platy food materials, and the two platy food materials are bonded and united making use of the surface not yet completely cooled and solidified of the monolayer platy food materials, and thereby producing a layered laminated cheese food and the like consisting of two layers. In order to obtain a three-or-more-layer laminated structure, the fluid food materials which solidify when cooled are quantitatively supplied successively at a certain thickness in a plate form on the cooling and carrying sides of the cooling and carrying devices, cooled while being carried to form monolayer platy food materials, or if necessary, more fluid food materials which solidify when cooled are quantitatively supplied successively at a certain thickness in a plate form over the platy food materials, cooled while being carried, thereby forming multilayer platy food materials, and/or the platy food materials are bonded and united to form multilayer platy food materials, and the fluid food materials are quantitatively supplied successively between the two monolayer and/or multilayer platy food materials in order to unite the two platy food materials and the fluid food materials comprising the layers between the two platy food materials.

A rotor for a rotating electric machine comprises a rotor core, and a plurality of rotor conductors wound on the rotor core. At least one of the rotor conductors is provided with a cooling groove, and edges of at least one of the cooling grooves are rounded by a radius process to reduce peak stresses that may be induced around the edges of the cooling groove.

An apparatus for forming openings in printed circuit boards includes a work table for supporting the printed circuit boards, and at least one drilling unit movable relative to the work table. The apparatus uses drills each having a shank, a collar fitted around the shank at a predetermined position. For holding these drills, at least one first tool holding device is provided on the work table, and at least one second tool holding device of a magazine type for containing the drills parallel to each other is removably mounted above the work table. At least one transferring device is provided to operate to push a desired drill out of the second tool holding device of the magazine type, hold the pushed-out drill and transfer the same to a position where it is aligned with the drilling unit.
