A capacitor includes a dielectric substrate and a large number of filamentous conductors formed to penetrate through the dielectric substrate in a thickness direction thereof. An electrode is connected to only respective one ends of a plurality of filamentous conductors constituting one of groups each composed of a plurality of filamentous conductors. The electrode is disposed in at least one position on each of both surfaces of the dielectric substrate, or in at least two positions on one of the surfaces. Further, an insulating layer is formed on each of both surfaces of the dielectric substrate so as to cover regions between the electrodes, and a conductor layer is formed on the corresponding insulating layer integrally with a desired number of electrodes.

An inductor includes a core substrate including minute column-like electrical conductors extending between a front surface and a back surface of the core substrate. Each column-like electrical conductor is insulated from adjacent column-like electrical conductors by being surrounded by an insulating material. Insulation layers are formed on the front surface and the back surface of the core substrate, respectively. At least two connection electrical conductors extend through each of the insulation layers. Each connection electrical conductor is electrically connected to a plurality of the column-like electrical conductors. Wirings are formed on each of the insulation layers to connect said connection electrical conductors to each other electrically. The wirings, the connection electrical conductors and the column-like electrical conductors are connected to form a coil in a three-dimensional manner.

A superabrasive tool such as a superabrasive grindstone (101; 102), a superabrasive dresser (103; 104; 105) or a superabrasive lap surface plate (106) includes a base (20) of steel and a superabrasive layer (10) formed on the base (20). The superabrasive layer (10) includes superabrasive grains (11) consisting of diamond grains, cubic boron nitride grains or the like and a holding layer consisting of a nickel plating layer (16) and a bond layer (17), or a brazing filler metal layer (18), holding the superabrasive grains (11) and fixing the same onto the base (20). Grooves (12) or holes (14) are formed on flat surfaces (19) of the superabrasive grains (11) exposed from the holding layer (16, 17; 18). The holding layer (16, 17; 18) holding and fixing the superabrasive grains (11) so that the surfaces of the grains are partially exposed is formed on the base (20). The grooves (12) or the holes (14) are formed by irradiating the surfaces of the superabrasive grains (11) exposed from the holding layer (16, 17; 18) with a laser beam (50). Working of high accuracy can be performed by forming the grooves (12) or the holes (14) on the surfaces of the superabrasive grains (11).
摘要:
A package containers rack frame for storing, transferring and displaying relative light-weight packages. The rack frame is constructed of a pair of side frames and a plurality of support bases which are removable from the side frames. The support bases are engaged into sockets on the side frame without disassembling of the side frames. The side frames have folding elements that are for controlling the distance between the side frames, which are folding and/or unfolding. The frame members of side frames has an adjusting member for adjusting the distance between the side frames, which thereby permits use of different width or height dimension for the containers. The support base has upward curved projections at both ends thereof for restricting in lateral movement of the containers.
